Explanations? Im really confused and if it would make a diffrence if those were checked tell me please!

The PCI-E bus can switch from 1.1 or 2.0. I believe this a power saving feature that can be changed by modifying your power plan settings. The same can also be said with the missing checks for CUDA and Direct Compute as our NVIDIA cards can power down and switch to the Intel graphics resulting in a mixed GUI result. It might also just be a bug from the software itself. Try relocating your GPU-Z program if its placed in a different partition.

Registered to NBR to post in this very good thread.

Was looking for a way to overvolt the GT550M to improve stability and maybe push the clocks a little more.
Installed your modded BIOS for GF106 GT 550m BIOS Version 70.06.32.00.05 : so far so good, allowed me to OC to 800/1600/1000 from 750/1500/1000 (last stable clocks at 0.86V).
OCCT test + Skyrim test PASSED.

Thanks for the good work OP.

what about some undervolted versions? I noticed most happy users of my modded XPS 15 Bioses are using undervolted versions, for some reason, low voltages seems increase stability at L502X laptop , or at least is what the users reported there, I am also experiencing extra stability on OC the 525M card with 0.83v instead the stock 0.95v, lowering voltage also improved a lot the temperature.

after undervolt, repasting and removing the dust filter I never experienced any other crashes, or temperature Issues.

Hello Sharadoes,

I have tried to look at my settings in the gpuz and it turns out that I have similar concerns as the MKIVator. I can also see that the two options (CUDA and DirectCompute) are not checked in my GPUZ window. You are absolutely right in stating that the PCI-E Bus can switch 1.1 to 2.0 and I have check it personally. Please take a look at the two screen shots to have a closer look. However, I would point out that am using a different version of Nvidia drivers. The GPUZ program is running from my "C:". I have currently overclocked my GPU but I wish to overclock my voltage so that I can get a higher clock speeds. But, I will only proceed after any suggestions from you experts. Thank you.

Sumi

Hello,

I have used the appropriate file that is available on the first page of this thread for flashing my GPU BIOS. I can notice that my "maximum voltage" has gone up to 0.9120 V. However, if I look at the "current reading" if my system is not under load, then the voltage is still 0.8120 V. I think this is good. Now, I will go ahead and overclock my system to see how much I can get out of it. Please have a look at the screens for the voltage confirmation. Thank you.

Regards
Sumi

Hello, I registered on this website because of this post... awesome job! . i want to over-volt my 550m gpu, but i see that you have not made one for my gpu bios version "70.06.32.00.04"

Is there a way for you to make one for my version? or can i install one of the GF106 bios mod and it would still work?. my gpu is not stable on high overclock settings "760mhz", and i would love to make it stable at 760 core-clock or even higher.




Thanks in advance

Thanks Sharadeos I gave it a go and am now running at 800 1600 1000 temp 68c after 30 mins on Skyrim. Ambient room temp 21c and using latest nvidia certified drivers.

I do however think that I have been very lucky with my GPU though as it has always seemed to run much cooler than everyone else's on here.

An undervolted version of the A16 Bios would be great ... I don't need a higher voltage, because I don't need the overclocking capability at the moment. A lower voltage would help me to reduce the battery drain and the use of the fan.

Hello Matt,

Can you please tell me which version of Bios Mod you have used. Also, if you can give me a list of programs you have used for the overclocking, It would be really helpful... Thank you.
