Hi, I'm a bit of an overclocking noob (as in a lot) so I'm looking for some help overclocking my E8400 on a Gigabyte EP43-DS3L.
I've tried to follow some of the beginners guides, increasing FSB by a little bit and setting the RAM speed back but its not working... After exiting the BIOS it won't POST the first time, then it'll restart with the CPU settings restored to default and boot fine. Its been annoying me a lot, if you guys could post BIOS settings that would be great. Thanks.
I did, I'm having a lot of trouble though. I can't get the computer to POST changing any settings. Even moving the FSB up a little bit and adjusting other settings. I'm only trying to get to 3.6 GHZ right now and I moved from 3.00 to 3.16 (FSB 350) and it doesn't POST. Then it'll restart a few times and the old settings will be restored.
I was wondering if there are settings I'm missing or something?
Heres my MB Intelligent Tweaker:
Robust Graphics Booster->Auto
CPU Clock Ratio->9X
*****Clock Chip Control*****
>>>Standard Clock Control
CPU Host Clock Control->Enabled
CPU Host Frequency (Mhz)->333
PCI Express Frequency (Mhz)->100
>>>Advanced Clock Control
CPU Clock Drive->800mV
PCI Express Clock Drive->800mV
CPU Clock Skew->0ps
MCH Clock Skew->0ps
*****DRAM Performance Control*****
Extreme Memory Profile (X.M.P.)->Auto
(G)MCH Frequency Latch->333 Mhz
System Memory Multiplier (SPD)->2.40B
DRAM Timing Selectable (SPD)->Manual
>>>Standard Timing Control
CAS Latency Time->5
What's your CPU's Vid? What is the spec voltage of your RAM? What is the speed and latency rating of your RAM? Have you tested your system (without OC) to make sure it's stable (i.e. run memtest86+ O/N without errors and run a prime95-based stress testing program for at least many hours without errors)?
A lost of OC problems are due to incorrect memory freq. When increase FSB, memory freq goes up as well. Try to keep memory freq low like ratio: 1:1 with FSB freq so you can at least eliminate memory as a culprit of your problem.
