Motherboard p35-ds3r, q6600 G0, 2x2gb G.skill 8500 1066 ram, ati 4870, and OCZ 700w power supply. I'm new to overclocking.
I recently overclocked my q6600 G0 to 3.0ghz @ 1.267v. Yesterday I decided I wanted to overclock a little more, so I knocked the fsb to 370 (3.3ghz) changed the vcore to 1.29 and tried running prime95.
Prime95 (large fft) wouldn't last for more than a minute before it would just dissapear. So I started increasing the the cpu voltage, finally got around to 1.34v and programs seemed a little bit more stable, not perfect by any means.
Prime95 would last for about 10 minutes to 1 hour before it would just dissapear. I increased the ram voltage and fsb voltage by +.2v
@1.37vcore (55c cores load) my computer seemed alot more stable.
I could run prime95 for about 1-2 hours before crashing/dissapearing at 384k, after messing with settings all morning I decided to play some tf2, about 10 minutes in I crashed.
I went back to my bios knocked the fsb down to 360 and underclocked my ram down to 760Mhz (was 880), started tf2 up again crashed about 3 minutes in.
Got some error messages "cannot read memory" "cannot access memory" (not sure what they said) about 10 of them. They looked like ones I would get when I activated multi-core support and crashed in tf2 so I didnt really pay attention to them.
Tired of messing with all these settings and not getting a stable overclock I decided to go back to 3.0ghz.
I hit my reset button and now I dont get any video at all. At first I thought I fried my ram, even though I had the volts set correctly, but after trying out different things I realized my computer seemed to post properly.
So, I waited 2 minutes after powering on, hit the arrow keys down 2x and hit enter. I could hear windows logging in. So I know my ram, cpu, and hard drive are all working ok. Im just not getting a video signal, I tried resetting the bios, taking out the battery for 2 hours, trying my old 3870, nothing has worked.
Bios settings:
Cpu clock ratio---9x
cpu host frequency---360
pci-e----100mhz
C.i.a. 2----disabled
Performance Enhance-----Standard
Memory multiplier-----2:00 or 2:40 can't remember, it was underclocked
System voltage control
DDR2 Overvoltage-----1.8v(base) +.2v Ram 8500 1066 2.0v-2.1v
Pci-e overvoltage control----Normal
Fsb overvoltage control ----- +.2v
(G) MCH overvoltage control--- Normal
Cpu voltage control---- 1.37v
Normal Cpu Vcore 1.25v
Did I fry my motherboard or my graphics card? If so, how? I thought I was within the safe zone as long as I didnt bring my cpu vcore up too much and my temps were fine. Anyway to fix this? Any help is greatly appreciated!
