b1te Posted October 8, 2013 Share Posted October 8, 2013 Hi everyone, the GPU in my system seems to have some issues. When I install a driver and do not reboot everything is fine. The GPU clocks at 614 Mhz as it is supposed to do. However, as soon as I reboot the GPU will not clock any higher than 324 Mhz while the Memory still will clock at 1400 Mhz. I also can't use tools like Afterburner to change the clock speed of the GPU. It will always run at 324 Mhz. However, the clock of the memory can still be altered. I think I tried almost everything (e.g. tried different drivers), I already reinstalled Windows (I use Win8) but the issue stayed the same. Do you guys have any suggestion what else I could try? Might the vbios of my graphics card be currupted? Could it help to flash one of svl7's unlocked ones? Any other ideas? Thanks in advance for all your help!

svl7 Posted October 8, 2013 Share Posted October 8, 2013 What's your vbios version? That should not happen if the 670mx is the standard card of your system. Quote Link to comment Share on other sites More sharing options...
b1te Posted October 8, 2013 Author Share Posted October 8, 2013 It's the system's standard card.vbios according to gpu-z: 80.04.5B.00.22 and subvendor is MSI Quote Link to comment Share on other sites More sharing options...
svl7 Posted October 8, 2013 Share Posted October 8, 2013 And you're not on battery? When you run the GPU-Z render test the GPU stays at 324MHz? Does it idle at 135MHz? Quote Link to comment Share on other sites More sharing options...
b1te Posted October 8, 2013 Author Share Posted October 8, 2013 No I'm not on battery. On battery mem clock would be too low as well, right?After like 4 new installs of Windows I found at least kind of a solution:I switched the BIOS from UEFI to legacy an reinstalled Win 8. Now, Afterburner would still always show the GPU at 324MHz in every case (idle, load, etc.), but GPU-Z gives real values (135MHz idle, 614MHz load). Even OC works (up to +135Mhz ;-) ). I verified that by 3D Mark 11 scores and Heaven Benchmark. However, if the notebook is set to hybernate or stand-by and then restarted the GPU will always clock only up to 601MHz in load cases. Overclocking is impossible then, only underclocking works.GPU-Z render test now gives 614MHz and idle clocks are correct as well.So there are some issues left, but its nothing I can't live with. :-) I'd just love to know what the reason for all that trouble might be :-DAnd thanks for the help so far!! :-) Quote Link to comment Share on other sites More sharing options...
svl7 Posted October 8, 2013 Share Posted October 8, 2013 Ok, I'd recommend flashing the modified vbios that you can find in the Kepler mod thread, that might help you a bit.Your card won't work in UEFI mode since the vbios has no uefi part in it. If you don't want to use legacy mode then you would have to try a different vbios version. Quote Link to comment Share on other sites More sharing options...
b1te Posted October 8, 2013 Author Share Posted October 8, 2013 Yeah, I'll definitely try that once I have enough posts to download the mod vbios. And I will give some feedback here. Might help others with similar problems.I will have to download the MSI 670MX vbios as my card has 1.5GB vram, right? I suppose the Clevo one (3GB) would not work?Using legacy mode is fine for me. I don't see any difference to UEFI mode. Is there one? Quote Link to comment Share on other sites More sharing options...
