I did tend to use the VTT voltage a fair bit as Quad's thrive on those volts :)
All I could go by was that the board would display a red led on the bottom and blue led right above it. Don't know what that means but no video display on the screen, video card checked out though. Any ideas
Hi guys a have a few question about the board where you able to achieve that oce with 4gb of ram? does the thermalright ultra extreme fit on the board?
and does it support tri sli?
Just got the board in from the egg. You will have to VERY carefully bend that curving top heatpipe about 1 or 2 cm toward the first pci slot to fit, it's not even enough that you notice but it does work with my TRUE with about 1 cm clearance after the bend. I do advise you pull the heatsink/heatpipe array off and replace the dope with some AC Ceramic. My southbridge wasn't making ANY contact :o (seems to be a very common problem on every manufacturers boards now days, not exactly a tough QC problem so go figure). On that note the heatsink seems pretty cheap so I may look at replacing the array with some other sinks. Couple of the Thermalright HR-05 SLI's on the north and south bridges, they're HR-09 type 3 on the mosfets, and a Thermaltake Extreme Spirit II on the 200 chip between the PCI-E's for some color :) But only if I can get it to clock better than my xfx 680i LT (I sure hope it does because right now the best I can get is 3.3g stable with a G0 stepped chip 1.25vid).
will let everyone know my results in a few days when I have time to play with it.
I have tried OCing my E8400, but the best I've managed is 3.6GHz stable using:
400MHz FSB (1600MHz in BIOS)
9x Multiplier
CPU @ 1.24V (+0.0350V in BIOS)
NB @ 1.32V (+ 2 steps in BIOS)
I'm getting CPU temp of 23-25 idle, 33 under load. Cores are between 33-39 under load.
I managed to raise FSB to 1667, giving 3.75GHz, which booted into Windows, but kept locking up fairly regularly. Temps were one degree higher.
Any advice? I have almost no experience overclocking, sorry - but I've heard the processor is capable of 4.4GHz+ :-)
Can't remember the whole BIOS
Thanks for the quick reply (and fantastic review, big factor in me choosing the board)!
i bought this mobo and i wanted to buy an Cooler Master Sphere cooler ...but i do not know if will fit beacause of the zalman cooler onto the chipset ....
should i'll try another cooler like Cooler Master GeminII s?or the Sphere
i like a lot the Sphere but i do not know if will fit...thx
ps:sorry for my bad english:p

By the way nice review, did each core check out at 3.8Ghz in CPU-z, because many ppl haven't been able to pass 1333MHz FSB. If so, how did you get it to work?
Thank You
