Hi all!
First I want to congratulate you: this is the more complete and detailed thread on the X48T-DQ6 on the net.
I would like to submit you my problem, I hope you could help me.
I am not an extreme overclocker, I just wanted to find a stable and optimal setting for my
mobo/memory/processor and use the full potentiality of my hardware.
I just have a basic cooling, so I am not trying to reach extreme frequencies (specs are on my profile).
My first idea was to increase the
FSB to 400 in order to reach 1600MHz at my
RAM with a multiplier of 4.
Then, if possible, I would have further increased step by step the
FSB until the last stable frequency.
I changed my memory settings as suggested by the OCZ specs/forums and lower the
CPU clock ratio of 0.5.
All the settings are reported below at the end of the
post.
I ran prime95 for a whole night without any error.
Memtest also passes some hours without errors.
Although stability tests seem to indicate that my system is stable i get the following two issues:
1 - Sometimes, without any apparent reason, the pc doesn't
post, it cycle for three times, and boot with a fallback
FSB value.
2 - I get some instability while playing SOME games (not all), a
BSOD or it just blocks and I have to switch it off manually.
I tried 3
bios version (F4, F5, F6a), without solving the issue.
The
mobo supports 400MHz
FSB, so I thought that overvoltage is not required.
I am seeing that you pushed the
FSB to 440MHz without liquid cooling, and 500 with liquid cooling.
So I am struggling to find the right settings in the
BIOS.
Can you suggest me something by looking at my specifications?
I would love to reach at least 420MHz.
Actually I never touched the section "Advanced timing control", this could be my problem.
Thank you very much,
Danilo
