thanks, I'll try that

I have a fairly similar rig, although I'm running 8GB of the OCZ Fatal1ty branded DDR2-800Mhz ram. I can get the 3.4Ghz stable as rock with a 1:1 ratio set at 378Mhz (ram being slightly underclocked) but I can't seem to tweak her up to a 400Mhz OC by any means... well at least not by my stability standards / requirements.

But then again, 4x2048MB seems to be hard to get stable at any frequency and I'm afraid that trying to upgrade to a higher speed DRAM @ 8GB I'll just be pissing in the wind and end up with something less stable than what I already have.

I tried asking a rep from G.Skill if they had any product recommendations for something along the DDR2-1100 or DDR2-1066 range that I could run 4x2048MB and they gave me a line of crap about how this board is too unstable for 8GB for speeds higher than 800Mhz. On one hand it's nice that they were candid enough to tell me "no, we don't" but I'm not yet willing to believe their assessment of this board's capability to run 4x2048MB modules at higher frequencies... :sigh:

Well I am going to be shooting for 4ghz on my Q6600. I am trying to get 445 fsb stable for now but I am having problems. I am able to boot into windows but it fails with OCCT and prime95 right away

Here are my bios specs

graphics booster: auto
multi: 6x
fsb: 445
C.I.A. disabled
dram enhancer: standard
mch latch: 400mhz
multi: 2.00D

ram timings: 5-5-5-18

loadline: enabled
cpu vcore: 1.34375
cpu term: 1.34
cpu pll: 1.57
cpu ref: .903

mch core: 1.34
mch ref: .928
mch/dram ref: auto
ich I/O: auto
ich core: auto

dram voltage: 1.8 (defualt)
dram term: .900
channel a&b refs: auto

does anyone have any suggestions to try and make this stable?

edit: I had a few settings actually different in the bios so I changed them and I'm testing stable right now.

I fixed the settings and ran these exact settings in the bios and it will run for 12.5 minutes with no problems with OCCT then fails. Anyone know what settings I should try?

I am troubleshooting my new system. Can anyone confirm whether or not the leds on the board stay litten when computer is running or they just stay on during start up?

Bump up mch, that high of fsb requires a lot more then 1.34, try 1.4V and see how long that holds.

From my experience LEDs just lite up during start up, then go off and stay off regardless of cpu load (idle vs prime95/IBT).

thanks a bunch, is 1.4 safe for this board? If so, what is the max safe for this board?

LLC is also enabled and my vid is 1.2!

Max recommended on air cooling is 1.6V, but the heatsinks that Gigabyte chose to use dissipate the power generated rather well. I'm not sure whether someone commented about this here or over at xs but even at 1.6V northbridge stays rather cool (30-40C).

43C at 500 FSB link.

Hardwarecanucks didn't specify the MCH core voltage but it should be fairly high considering the 500 fsb.

Wow, thats a great q6600 you got there. I wouldn't be surprised if you managed to pull of 4.0 Ghz 24/7 with the right settings with such a nice chip.
