Well, I have to say that I really, really like this rig so far. I think I shot for the sky thinking 4 Ghz was possible on air cooling, but I am still trying to see what more I can get out of this thing. So far, 3.6 Ghz looks solid, and I didn't have to adjust any voltage. I'm confused about the CPU-Z readings vs. the BIOS. I don't know which is correct. Let me first give you some examples of my tests:
Overclock Settings and results:
Worked: 9 x 360 Mhz = 3240 MHz, vCore set to Auto, CPU-Z reports 1.405 vCore, Mem @ 576 Mhz
Failed (Locked Windows): 9 x 400 Mhz = 3600 MHz, vCore set to Auto, Mem @ 640 Mhz
Worked: 9 x 400 Mhz = 3600 Mhz, vCore at Manual..."Normal" setting, CPU-Z reports 1.296 vCore, Mem @ 540 Mhz
Worked: 9 x 400 Mhz = 3600 Mhz, vCore at Manual-Normal again, CPU-Z reports 1.296 vCore, Mem @ 640 Mhz
Failed (No Post): 9 x 425 Mhz = 3825 Mhz, vCore at 1.325, Mem @ 510 Mhz
Failed (No Post): 9 x 415 Mhz = 3735 Mhz, vCore at 1.310, Mem @ 510 Mhz
Failed (Windows Locked): 9 x 415 Mhz = 3735 Mhz, vCore at 1.325, Mem @ 510 Mhz
....skip ahead in tests a bit...
Failed (Orthos Failed): 8 x 475 Mhz = 3800 Mhz, vCore at 1.3562, CPU-Z reports 1.328 vCore, Mem @ 570 Mhz
Failed (Blue Screen): 8 x 475 Mhz = 3800 Mhz, vCore at 1.3625, CPU-Z reports 1.344 vCore, Mem @ 570 Mhz
Failed (Windows Locked): 9 x 425 Mhz = 3825 Mhz, vCore at 1.375, CPU-Z reports 1.344 vCore, Mem @ 510 Mhz
Sorry for all that, but it leads to some questions if any other Gigabyte P35 owners can contribute.
- Why is CPU-Z reporting a different voltage? If it's correct, why did the motherboard set at Auto ramp the vCore up so high (see first test)?
- Does my memory speed sound right? Supposedly, I had it as high as 640 Mhz (in CPU-Z) and it was working under that setting (without Auto voltage on).
- I know I jumped around a bit, but I think I've hit a deadend on 3.6 GHz. Unless I can trust CPU-Z that the voltage isn't as high as the BIOS says and keep going up.
Thanks for any thoughts.
