Is There Such A Thing As Too Many Computers?: June 2011

Planning

So after reading about the modded Sony Vaio UX, I've been inspired to mod a Sony Vaio TXN27N.

Quote from above link regarding components and cost:

Hum… insane amount… as a 280 has been also made, as a prototype, except wifi-n and it uses a e169 through external usb… I funded some tries to have 2gg ram also (failed…)…
Then, now that it has been made once, it costs the components+work:
100$ for the modem/cellphone

Then comes the crazy amount of work, to have it done, I let you ask Anh on http://www.micropctalk.com for a quote…

Original specifications:

Release Year: 2007
Chipset: Mobile Intel 945GMS Express Chipset
Processor: Intel Core Solo Processor U1500 1.33 GHz, 533 MHz FSB, Socket PBGA479
HDD: 100 GB 1.8" Toshiba MK1011GAH, ZIF interface
Memory: 2 GB DDR2 PC-5300 (see memory specifications on crucial.com)

Planned upgrade specifications:

Processor: Intel Core 2 Duo Processor U7700 Socket P, 1.33 GHz, 533 MHz
HDD: 1.8" SSD HDD, I got the Renice Z2 1.8" ZIF SSD 128 GB from mydigitaldiscount.com
Memory: ~~4 GB DDR2 PC-5300, maybe 8 GB DDR2 PC-5300~~, doesn't work, TXN will not POST after putting in a 4 GB memory module.
WLAN: 802.11n
Additional disk space: Cardbus CompactFlash Adapter with 128 GB CompactFlash Card
Replace internal Sony Vaio TXN WWAN module with a Sony Vaio TT WWAN module that supports mini PCIe WWAN module so that I can replace the card with something else, like more diskspace SSD mini PCIe card, or a different WWAN mini PCIe card. The Sony Vaio TT WWAN module looks like it'll fit better than the Sony Vaio TZ WWAN module.

Actual upgrade specifications:

Processor:
HDD: Crucial M500 240GB mSATA SSD with mSATA to 1.8" PATA ZIF adapter
Memory:
WLAN:
Additional disk space: Samsung 160GB 2.5" PATA HDD with Optical Bay Hard Drive Caddy (OBHD9-PATA-B), Black, 9.5mm from newmodeUS.com
Additional disk space: Aska CF32F CompactFlash adapter with 64GB SanDisk Extreme Pro CompactFlash Card
Additional disk space: Lexar 32GB Memory Stick PRO Duo

The processor I've found on eBay, easy enough. Now the really big problem. The U1500 is soldered onto the motherboard. So the question is, how do you replace it. As it turns out, it's not at all that complicated. All you need is BGA (ball grid array) aka reballing service. A quick google search on the internet for "BGA service" or "reballing service" will yield a lot of results. Now, I've been weeding through all the available services out there and here's my short list. PLEASE NOTE, I have not yet used these services, so make sure you take this with a grain of salt do your part and do your own research before venturing forth and using a particular vendor.

List of BGA/reballing services:

Vaiorefurbs - This vendor is on eBay and doesn't officially have reballing service listed. Contact the vendor for further details. This particular vendor is in the UK.
Avon PC Pitstop

If you're in Spain, I looked up these vendors (yes, I realize this seems very random, but here it is). Additionally, in Spain, they're more commonly known as reballing services:

ON/OFF Computer - Barcelona
Microcomputers - Madrid

I've been doing ALOT of research on 1.8" SSD drives for the Sony Vaio TX and Sony Vaio TXN, but nothing seems definite. I've read so many conflicting articles, I don't really know what to believe. So I'll leave it up to you to decide what to go with, but I'll let you know on my end what I ultimately go with and if it works or not. Check out the Upgrading Vaio Tx forum topic at Notebook Review for more information. For the time being, I've got my eye on the 128 GB PhotoFast 1.8 GMonster- ZIF V4 SSD. RunCore looks like they have a drive that will work in the Sony Vaio TXN: RunCore Pro IV 1.8'' ZIF PATA SSD and RunCore Pro IV 1.8” PATA ZIF PLUS SSD.

When it comes to laptop memory, I don't know if manufacturers are lying to us or if it's just that the memory just wasn't available when the laptop was manufactured, but I've been noticing that laptops are capable of handling more memory than the manufacturer listed maximum memory. This isn't to say that it might be futile, 4 GB RAM isn't going to fully accessible on a x86 (32 bit) machine. Windows will only use 3 GB, but what's wrong truely maxing out the memory. DDR2 PC-5200 also comes in 4 GB sticks, so I'm wondering if the TXN will take it. The U7700 is a x64 processor, so if the hardware recognizes it, I'll have full access to the memory in Windows 7 x64, however, I'll lose the Cardbus CompactFlash Adapter. The CF32F doesn't work with Windows 7 x64.

Bet you thought that the Cardbus CompactFlash Adapter didn't exist any more after Delkin and Viking stopped producing it, didn't you? Well, it's actually still available. Where you ask? Japan! See here. Pop a 128 GB CompactFlash card into that bad boy, permanently add it to your pc card slot that you probably never use and you've got a permanent 2nd harddrive bringing you closer to the 256 GB fixed disk range.

2011-06-27 Update

The Sony Vaio TXN27N upgrade project is now officially underway. I received the Cardbus CompactFlash Adapter from Amazon Japan. I ordered the Aska CF32F Cardbus CompactFlash Adapter (ケンコー・トキナーアスカ製 CF/MD用メモリカードアダプタCF32F ノートPC用 086448). It's the only one that I could find with my haphazard searching technique on a foreign language website.

Amazon Japan Cost in USD with shipping cost: = 50.97
tenso.com mail forwarding service in USD: 21.53

I haven't order my CompactFlash card for the adapter yet, so I can't post performance metrics just yet. I was planning on getting a 128 GB compact flash card, but as it turns out, there's ONLY 1, the SanDisk 128 GB CompactFlash Type 2 Flash Memory Card SDCFXP-128G-X46 - Black and it commands a premium at $1500. With that said, I can't seem to get a good answer/review on the Photofast 64 GB CompactFlash card, so I'm going with the SanDisk 64 GB CompactFlash card. It's about $200 more at a total of $500, but for the peace of mind, it's worth it in my opinion. The last thing I want is the card to fail on me as this machine machine is being actively used.

The card is manufactured by Aska Japan. Drivers and manuals can be found here.

The manual doesn't make any mention of Windows 7 x64 support, but the reviews on Amazon Japan state that Windows 7 x64 is not supported, but I'll try it myself just to be sure and post the results.

2011-06-27 Update

Stopped by the post office to pickup my Intel Core 2 Duo U7700. I picked up the BGA (ball grid array) variety, instead of the PGA (pin grid array) variety. My understanding is that if the CPU is soldered onto the mainboard, then the processor has the BGA socket type. Next stop, BGA service for processor replacement. The U7700 came with some thermal compound, but I'm going to be getting some silver thermal compound instead. The processor is going from a single core 1.33 GHz to a dual core 1.33 GHz processor, so I'm a little nervous about heat management.

2011-06-29 Update

I've received the 64GB SanDisk Extreme Pro CompactFlash Card! The CompactFlash card inserts into the Aska CF32F CompactFlash adapter smoothly. As always, DO NOT force the card into the adapter if there is resistance. When inserted into the computer, it sits flush and there's no worry about damaging any components when left in the computer (see photo below).

The CompactFlash card and the adapter install flawlessly on Windows 7 x86, unfortunately, it DOES NOT work on Windows 7 x64. The device shows up as SanDisk SDCFXP-064G SCSI Disk Drive. I can understand why the device doesn't work on Windows 7 x64. For those of you who own the Adaptec APA-1480 cardbus SCSI card, you know that it doesn't work with Windows 7 x64. This is probably something of the same situation.

I've run some CrystalMark benchmarks using the Aska CF32F cardbus CompactFlash adapter and the overall results are promising and acceptable for a 32 bit adapter. The advertised speed of the SanDisk Extreme Pro is "up to 90 MB/s" write speed.

The test system was a Lenovo T60, 4 GB RAM (3 GB usable), Intel Core Duo T5600 1.83 GHz.

SanDisk Extreme Pro CompactFlash Card exFAT formatted with Aska CF32F

SanDisk Extreme Pro CompactFlash Card NTFS formatted default block size with Aska CF32F

SanDisk Extreme Pro CompactFlash Card NTFS formatted 1024 size blocks with Aska CF32F

Western Digital Scorpio 12GB WD1200BEVS SATA

Conclusion, the default format of the disk exFAT performs the best. However, to use this device as an extra HDD, I need to be able to write files larger than 2 GB (the upper limit for FAT32). Formatting the disk using NTFS and the default blocks results a significant hit to the write speed. I've read that Linux does a better job with SSD drives and based on what can see here, it probably has something to do with the block size in Linux. The file system in Linux uses a 1 KB block size. I reformatted the CompactFlash card using NTFS and a 1 KB block size and I got the write speed back up closer to the original exFAT specification. I compared the CompactFlash performance with the SATA HDD (Western Digital Scorpio 12GB WD1200BEVS) and it beats it in most cases except the random write test with small files, which is again consistent with the purpose of the CompactFlash, pictures and digital video. The card was designed for sustained write speed. The SanDisk Extreme Pro CompactFlash states "Video Performance Guarantee enabled to ensure Full HD video recording at 20 MB/s minimum sustained write speed".

2012-01-03 Update

Attempted to upgrade the RAM beyond the 2 GB specification. I inserted a DDR2 PC2-5300 2GB memory module into the memory slot and the computer will not post.

2012-01-03 Update

Found out that Toshiba makes a 240 GB PATA ZIF HDD on eBay. Curious to see if it would work on the Sony VAIO TX/TXN.

2012-03-05 Update

Discovered a list of 1.8" ZIF SSDs that lists 1.8" ZIF SSDs in order of preference by performance and battery life. Additionally, I've discovered another brand of 1.8" ZIF SSD that may be a better choice in terms of reliability, Renice K3VLAR. A review of the Renice K3VLAR on forum.notebookreview.com can be found here. There is additional information to bypass the UDMA2 limitation here. mydigitaldiscount.com lists the Renice 240GB K3VLAR E (K2E) as compatible with the Sony VAIO TXN.

Installing Windows 8 RTM

Today Windows 8 RTM became available and reading that Windows 8 was designed with netbooks in mind, I decided to give it a shot and install Windows 8 on the Sony VAIO TXN27N. So far, I've been having a very rough time.

Windows 7 to Windows 8 Upgrade

The first thing I tried was an in place upgrade from Windows 7 to Windows 8. After upgrading to Windows 8, Windows crashed on continuously on shutdown and the system was generally unresponsive. I didn't have the patience to hunt down the problem, so I decided to do a fresh install.

Windows 8 Fresh Install

Warning 8/16/2012 3:38:37 PM Diagnostics-Performance 500 Desktop Window Manager Monitoring

The first problem I ran into was thrown by the Desktop Window Manager: The Desktop Window Manager is experiencing heavy resource contention.

To resolve this issue, simply install the Intel chipset drivers.

Windows 8 crashes on shutdown

The below Sony VAIO TXN system drivers cause the Windows 8 to crash when shutting down:

Sony® Firmware Extension Parser Driver
Sony® Programmable IO Control Device Driver
Sony® Shared Library
Sony® Utilities DLL Update
Sony® Notebook Utilities

I discovered that the Windows 7 drivers for the Sony VAIO TT work very well. Use as many of them as you can. Get the Sony VAIO TT229P drivers here.

MsMpEng.exe

Next the issue was MsMpEng.exe over utilizing the HDD. See my post on MsMpEng.exe Hell. Apparently Windows 8 is preinstalled with Microsoft Defender. Simply disable Microsoft Defender.

Final Thoughts

I'm still playing around with Windows 8, but I'm heavily leaning on going back to Windows 7. Thus far, as long as Windows 8 isn't resource bound, it works really well. But when Windows 8 is busy, it's REALLY slow. The good news is that I've learned that the Sony VAIO TT299P Windows 7 drivers work really well with the Sony VAIO TXN.

2012-09-07 Update

Well, it's official, frustration has won out. I want to use this computer more often, but the performance needs lots of help. In general, everything works well except video, but what's the point of dragging it around if I can't watch something on it?

I've purchased the Renice 240GB K3VLAR E (K3 E) 1.8" PATA 40-Pin Zif SSD Solid State Drive for PC and Mac - RN-K3E-Z1856 here from mydigitaldiscount.com. Still waiting for shipping confirmation, though.

2012-09-13 Update

Along with ordering an SSD for the Sony VAIO TXN, I got a Sparklan WPER-172GN 802.11n/b/g USB Half Mini Card from embeddedworks.net. According to an forum post on forum.notebookreview.com, the mini PCIe slot where the WWAN sits could be USB based. Well, after putting in the USB WIFI mini PCIe card, enabling the slot, it works!

Install the Sony SmartWi Connection Utility.
Browse to the SmartWi Connection Utility installation path: C:\Program Files\Sony\SmartWi Connection Utility
Execute TurnOnWWAN.bat as Administrator
Windows will enable the slot and recognize the USB mini PCIe card.
Get the drivers SparkLan WPER-172GN here at sparklan.com.

2013-01-08 Update

I attempted to replace the 100 GB 1.8" HDD with a StarTech Compact Flash (CF) to ZIF/LIF Adapter. The ZIF/LIF connector doesn't tightly fit against the ribbon cable inside the Sony VAIO TXN. I tried taping the ribbon cable in place as well, but it still didn't work.

Next up, I tried to replace the CD/DVD ROM drive with a HDD caddy. I originally tried the this SATA to PATA HDD caddy from amazon.com. The BIOS picked up the 250 GB HDD that I put in it, but Windows didn't see the drive. I ended up using the this Optical Bay Hard Drive Caddy (OBHD9-PATA-B), Black, 9.5mm from newmodeUS.com. The largest PATA HDD I could find was a 160 GB. I thought that PATA drives were available up to 320 GB, but I couldn't find one.

2013-07-09 Update

So I finally got around to getting a 1.8" ZIF SSD! I have the Renice K3VLAR 1.8" PATA Zif SSD 128 GB, see my post Experience with Renice SSD for more information. After a rough few months, I've got the compatibility issues worked out and it's WORKING!

I was also futilely attempting to upgrade the CPU from the stock Intel Core 2 Solo U1500 1.33 GHz to a Intel Core 2 Duo U7700. I sent the computer off to MixCat Computers in Kissimmee, Florida. The bad news is that they tried to replace the processor and they couldn't get the U7700 to work and then they tried to put the original U1500 back on and the computer STILL didn't work. Yikes. On top of that, I was missing some screws. Oh well. Good news is that I had a spare motherboard and they didn't STEAL it from me like Anh Nyugen from micropctalk.com who stole my Sony VAIO N505VX, see my previous post.

Overall, I will recommend MixCat Computers, but not for BGA service to replace laptop BGA CPUs.

To sum up, the Sony VAIO TXN27N is working with the Renice Z2 SSD and replacement motherboard with the original Intel Core Solo U1500.

2014-02-11 Update

I've been having problems with the PC card slot. I originally thought the PC card slot was damage when the technician at MixCat computers put it back together, but I purchased a replacement, but the problem is persisting. I'm thinking something with the replacement motherboard is damaged. I've purchased another Sony VAIO TXN27N motherboard and it has fixed the problem.

Additionally, as of 2014-02-11, the Viking Components 32bit CompactFlash cardbus adapter has popped back up on amazon.com.

2014-05-04 Update

I've continued to have problems with the Renice K3VLAR 1.8" PATA Zif SSD 128 GB.

I found a mSATA to 1.8" PATA ZIF adapter here on amazon.com. I paired it with a Crucial M500 240GB mSATA SSD and it works, NO DATA CORRUPTION! Please note, it goes in upside down.

2014-06-15 Update

So the fun never stops with the Sony VAIO TXN27N. I'm still trying to replace the stock Intel Core Solo Processor U1500 1.33 GHz, 533 MHz FSB, Socket PBGA479 processor with the Intel Core 2 Duo Processor U7700 Socket P, 1.33 GHz, 533 MHz. This time, I'm going with a local BGA rework shop, Xmoddz.com, in Springfield, Viriginia (VA). I gave them the original Sony VAIO TXN board with the Intel U7700 processor BGA reworked by MixCat Computers AND a NEW Sony VAIO TXN board that I bought to replace the motherboard that MixCat Computers worked on with a Intel U7700 processor on a Sony VAIO TZ motherboard.

As of 2014-06-23, they've swapped the Intel U1500 with the Intel U7700 and they're telling me that the BGA rework was successful, but the BIOS is preventing the system from booting. They're calling in a BIOS expert to mod the BIOS to get the system to allow the Intel U7700. No word if the BIOS mod is successful yet, but I did find a Sony VAIO TXN board with an Intel U7600 here on ebay.com. I discovered this motherboard from a post on forum.notebookreview.com. Since I've already got Xmoddz.com working on it, based on what they tell me, I'll go get an Intel U7600 for them to BGA rework on to my Sony VAIO TXN27N motherboard.

Well, word came in that the BIOS mod is a no go, so I've purchased a Dell Latitude XT motherboard with the Intel U7600 1.2GHz processor on it. I'm having the Dell Latitude XT motherboard sent to xmoddz.com to remove the Intel U7600 and install the Intel U7600 on the Sony VAIO TXN motherboard.

2014-08-13 Update

Xmoddz.com got back to me and it looks like the Intel U7600 isn't working either. I've now taken the route of ordering the Sony VAIO TXN motherboard here on ebay.com where the Intel U7600 is already soldered on. I'll check back in when I get my equipment back from Xmoddz.com and when I get the new motherboard from ebay.com.

2014-08-23 Update

I got the motherboard from ebay that is described as being a Sony VAIO TX/TXN motherboard with the Intel U7600 processor on it. However, when I received it, it was a Sony VAIO TX board with an Intel U1300 1.06 GHz on it. Not cool. I'm currently in talks with the vendor to get the right part per the description, but I'm starting to think it doesn't exist.

As of TODAY, 2014-08-23, I'm calling BS on the Sony VAIO TXN being able to be upgraded from a U1500 to a U7700 or U7600. If there's anyone out there who says otherwise, I want to see a screenshot of the TXN BIOS showing the U7700 or U7600 installed and I want a copy of the BIOS. Xmoddz.com is telling me that it's not possible, and I've tried BOTH the U7700 and the U7600 (just read through this blog entry, it's starts in 2011 and that's not including the years before where I didn't keep track of the information and research I did trying to get the U7700 on the Sony VAIO TXN27N).

So based on the information on the Intel ARK advanced search regarding the Sony VAIO TXN27N chipset, the Mobile Intel 945GMS Express Chipset, the chipset is compatible with the Intel Core Duo Processor U2500 1.20 GHz. It's not the Core 2 Duo, but it should still perform better than the Intel Core Solo U1500 1.33 GHz given the extra core. Based on the Intel U1500 vs U2500 CPU comparison on cpu-world.com, there's not a whole lot of difference. They have the same microarchitecture, the only difference is the number cores and thus the resulting power consumption is higher.

I have currently purchased a Dell Latitude D420 motherboard with the Intel U2500 here from ebay.com on it to be transferred to the TXN27N. I've hand delivered it to Xmoddz.com and I'm waiting to find out if the upgrade works.

This is going to be my last attempt to upgrade the processor on the Sony VAIO TXN27N. If it doesn't take the Intel U2500, I will no longer make any attempts to upgrade the CPU.

2015-03-31 Update

It seems that I didn't update this blog post after receiving the correct part from the ebay seller. I did get the proper motherboard with U7600 attached to it. It's a Sony VAIO TXN15P board with 512MB memory. After receiving the new board, I've been having excessive heat problems. Enough that the heat caused the processor ramped down to 200MHz. Yikes.

In my 1st attempt at a cooling mod, I placed a thermal pad over the heatpipe over the processor and two 20x20x0.5mm copper shims and a additional 20x20x0.5mm copper shim between the heatsink and the video processor.

2015-08-06 Update

The 1st cooling mod, worked, but it didn't achieve the level of cooling that the system needed to stay cool to prevent the processor ramping down to an unusable speed.

In the 2nd attempt, I added an additional copper shim over the video processor.

2016-06-12 Update

In my 3rd attempt, I tried attaching 15x15x1.5mm copper shims to the heatsink over the processor.

In the 4th attempt, I decided to try using Arctic Silver thermal epoxy and attaching copper shims to the heatpipe to increase surface area. I used a combination of 20x20x0.5mm and 15x15x0.5mm copper shims.

Using a speed saw (I have a Ryobi ZRP530 speed saw), I cut away parts of the top case to give space to the attached copper shims. I filed down the areas that I cut away to straighten and smooth it out.

Here's the final result. Since performing this cooling mod, the processor stays under 80C and the processor doesn't ramp down to 200MHz anymore. This is probably one of my more successful cooling mods. The next best thing I would have to say would be to weld on the copper shims for better heat conduction.

Sony Vaio TXN27N Upgrade
