x48T-DQ6 Overclocking help

Re: x48T-DQ6 Overclocking help

Great.

Its currently on 12 in bios and shows as 1 in memset. Everything below advanced timing settings is set to auto, including Static tRead.

Re: x48T-DQ6 Overclocking help

I don't trust what BIOS show for default, can you set it 12 manually in BIOS and see what you get in MemSet?

Re: x48T-DQ6 Overclocking help

you are correct, I set it to 12 in BIOS and memset shows 12.

Re: x48T-DQ6 Overclocking help

Hmmm so maybe it was set to 1? I have no Idea how it should be with DDR3 on x48, but maybe it is part of the problem.
See if you can get the system stable with Static tRead set manually.

Re: x48T-DQ6 Overclocking help

static tRead seems to be a bit dodgey, sometimes when I boot its at 7 and other times its at 12, 8 or 14.
Setting to to a static 7 or 12 and giving it a tiny bit of overclocking and I wont even get to POST.

Re: x48T-DQ6 Overclocking help

This is odd.
Just set it lowest possible and stable.
Maybe try the 4.00A multiplier as well?

Re: x48T-DQ6 Overclocking help

I set Tread to 7. multiplier to 4.00A and fsb to 370 and it seems to work, running a stress test now to see it it's stable.

Re: x48T-DQ6 Overclocking help

It didn't pass Orthos witht hose settings, "1:FATAL ERROR: Rounding was 0.5, expected less than 0.4". Sometimes the test ran for 30min + and sometimes for less than 1 minute.

Re: x48T-DQ6 Overclocking help

Try Static tRead 8, also post full settings.
Falling back to DDR-1333 with lower timings would not be much of a lose. The difference between memory performance is small and memory performance dows not make a big difference in overall performance.

Re: x48T-DQ6 Overclocking help

Orthos crashed with tRead 8 aswell

Re: x48T-DQ6 Overclocking help

Memory is overclocked 148(74)MHz above it's specs, try 3.33 multiplier.
Run small FFT for 2-3 hours to make sure this is not Vcore related problem.
If it's not the Vcore try +0.125 to +0.2 MCH OverVoltage, and +0.15 FSB OverVoltage

[badpop]

Re: x48T-DQ6 Overclocking help

I tried the same settings with 400 fsb and memory multiplier 3.00A, bluescreened after 5min of Orthos.

Running the same settings with standard 333 FSB now.

EDIT: it ran very nicely for 30min now and cpu core temp peaked at 43C. Unfortunatly I can't try it any longer because I have to run off for new year celebrations. Happy new year to you :)

Re: x48T-DQ6 Overclocking help

I upped the voltage a bit on MCH, fsb and vcore and tried 400x9, 3.00A spd and set it on Orthos, when I got back after 1,5h it had rebooted.

Re: x48T-DQ6 Overclocking help

Please post full settings.
Also fill your forum signature with your system specs, including board rev., BIOS vers., and a link to ram specs.
What BIOS version do you have? I see there's an F6D beta on GB site but even a later one F6e in the BIOS sticky at the top of the forum (page 2).
I am not beta BIOS fan myself, but it may be something worth looking at.

Re: x48T-DQ6 Overclocking help

Why are you tightening your timings before you max out the over clock on the CPU? may be i miss read as I did not read the whole thread.
