SPL Tech is an unknown quantity at this point
Only 3% OC'ed and already I cant boot?

The equipment I have is:
CPU: Core Two Duo 2.13 GHz. E6400
RAM: 2 GB. Corsair 800 MHz. XMS2 DDR2 (dual channel configuration)
GPU: X1900XT 512MB Connect3D
Mobo: Gigabyte GA-965P-DS3
PSU: 535 watt Enermax Whisper II
HD: 250 GB. Seagate Barracuda 16 MB.
OD: 52X DVD±RW
Monitor: Hanns-G 19" DVI LCD widescreen


I started overclocking the CPU in the BIOS tonight. I got to only 2.232 GHz. and I couldn’t boot. However I know that if I leave the computer unplugged for a few seconds the mobo woill disable the overclocking and let me reboot. So I did that and entered the BIOS as soon as booted up and reenabled the overclocking and Windows started fine overclocked at 2.232 GHz. Then after I ran all my benchmarking tests and such I restarted again to overclock more. This time I choose 2.264 Ghz. I saved it in the BIOS and once again I could not boot. So I unplugged the computer again to revert to OEM settings and rebooted into the BIOS. And once again I reenabled the overclocking but this time I increased the vcore from 1.325 volts (stock voltage) to 1.33125 volts (one click up) and saved and exit. The computer restarted and once again I could not boot. So I unplugged the computer again and reverted to OEM settings and I just left the overclock off and that is where I am now.
So what’s going on? I talked to people with this same processor that said they did not even have to touch the vcore until 2.8GHz. I am but barely 5% OC’ed.
Maybe I am doing something wrong. This is how I went about things:
I started out at 2.175 Ghz. I ran PC Wizard 2006 and benchmarked the CPU. I wrote down the Whetstone (FPU) Wheitstone (SSE2) and Dhrystone results. I then keept the program open to monitor CPU temp, voltage and loading.
Then I ran two instances of Prime 95 (one for each CPU) and ran the torture test on each and choose the in-place large FFT’s for max heat consumption. I ran the program for about 4 minuets with both CPU’s loaded 100% and recorded the average CPU temperature.
Then I close Prime 95 and open CPU Stability Test 6.0 and test the computer for stability for about 4 minuets.
It was stable every time.
As far as the steps I took in overclocking and the temperature recorded I got:
1: 2.175 Ghz., 47-48 C
2: 2.207 Ghz., 48-50 C
3: 2.232 GHz., 49-50 C
4: 2.264 GHz., 50-51 C
So whats wrong?
