Default Sony VAIO VGN-X505VP CPU / HD Power / Temps
Hi there everyone

This is for all owners of a VAIO X505 device....

I got a used one yesterday and ... it is not so easy to get that thing working nicely.
Thatīs why Iīd like to ask you for your support with informations about your own units.

I saw the speed with XP Pro is extremely low, unbelievably low....
Then I found out the CPU was throtteled down to 600Mhz and even lower !!!!

It took time to find CrystalCPUID as the perfect tool to manipulate Intel Speedstep, since the BIOS is giving absolutely no control and VAIO Power-Management fails its purpose - 600Mhz on "Adaptive" and "Performance" no matter what I do. The "Max Performance" is missing....

Now Iīm testing with Prime95 on 10x0.876V = ~ 990Mhz - CPU Temp is 93/94C (Notebook Hardware Control is the only tool showing that temp, nothing else worked, even CoreTemp, which doesnīt even start). HD is somewhere around 55C and extremely slow with average 15MB/S reading.... Crystalmark is not even reaching 8000 points and the RAM speed is similar to my Desktop SSD ...

Best of all, it is not possible to use the full CPU speed of 1,1Ghz since it gets so hot, it shuts down, no matter what Voltage I use, it canīt even run through a single CrystalMark.....

Very strange: Without using any CPU-Clock tools I get 1500 - 1700 D3D points in CrystalMark, but asa I start some of that tool type, even on higher CPU clocks, the result is significantly lower (1100-1200 points). I really canīt see or assume any reason for it. Anyone any idea ?

I also had serious problems with installing XP since the device shut down as soon as the first configuration part was reached. Now I think, that might have been a overheat shutdown since it is the same when the CPU overheats in Windows XP.

Whatever: Even on 1Ghz XP is incredibly slow !!! A UX1XN has a 1,3Ghz CPU and 1GB Ram, but it performs a lot lot lot better than the Dothan 1,1Ghz with 1GB Ram. It can not be compared by far ! Guess I also will have to install a trimmed down XP version.... The load is very high all the time mainly caused by "Services.exe" and "SVCHost.exe". Whatever is working behind those processes, probably useless services...

Okay, now questions for you:
- What are your temps at what clocks / voltages ?
- What are the clocks delivered just by XP and VAIO Power Management ?
- Do you also get 600Mhz on the adaptive performance settings or not ?
- For all those with a CPU upgrade to Banias 1,3Ghz the same questions.
- What are your CrystalMark benches and what about your D3D results ?

Thanks for your attention and please feel free to comment my experiences.
I really ask myself if my unit might be defective or if this is just normal.

Eingang, you mayhave an overheat issue with CPU.
Since X505 doesn't fan and whole area above keyboard is a heatsink, so the best suggest for you is to open your X505 and check the contact between CPU and upper case. You will need a tri-wing screw driver.
I also have X505ZP and max temp is about 60~62 degree celcius.
I haven't up grade mine to 1.3 yet.

hey maybe u need a better thermal compound Anh. Use minimum Artic silver. It really works superb! moves heat away from the cpu real efficient.

scary that the cpu heats to such high temps!!! Not sure if the dothan upgrade will reduce the temps by that much.

Like I said in another post and you have found out, the dothan CPU is so old and its very inferior to even the stock core solo that came with oldest UX, not to mention comparing to the amazing u7700.

Well, you are right for sure, something has to be done, but for now I do not have the right screw driver and I am not at home, so the thing has to wait.

I found out, there is some internal throttling at 69C, performance is significantly coming down at that temp. Crystalmark shows ca. 19000 points if the unit is cool, which is not even the case after a new boot in a room. I got that value outisde at 0C, inside even the first bench does not reach 18000 points. The second bench shows ca. 13000 and finally the fourth or fifth bench results in less than 10000 points at 80C+. Even fixed at 600Mhz and lowest possible voltage the CPU gets really hot after some time in lowest usage.

Fixing the CPU speed at 1,1Ghz results in stable performance but it is lower than 10000 and the CPU is melting down after some time....... That overheat issue is also the cause for the shut downs on Windows installation....

I am still searching for a service manual.....

got to love the ux. the unit externally does not get hot! clever insulated design puts all heat out through the exhaust port. only issue is it needs a fan to move the heat through the exhaust port

30 sec on Google [sony x505 service manual] turned up at least 2 pdf downloads for X-505 disassembly guides Here & here. (your google-foo is weak young grasshopper )

The exploded parts diagram with Sony part numbers is a bit more elusive.
