Uhm is it that difficult?Not just a 5 sec Bios change ?

What QPI/VTT voltage should I use with 1866 MHz RAM? and what is the maximum "safe" voltage?
Thanks in advance
I'd say anything under 1.35v (shown in for example Everest @ full load) is completely safe if your CPU stays at 75ish degrees.
There's no correct answer for how many volt you should be needing, since every chip is different. Just; turn up the speed, test, if unstable then more volts, test again and keep on going until you hit the sweet spot.

sadly it's not stable even at 1.38 QPI voltage, should I go for 1.39 or 1.40?

I changed the CPU water block yesterday I had been using the Swiftech GT but I was having a hard time cooling the i7. I installed the Swiftech GTZ and that lowered the idle temps by about 5C compared to the GT. I cool the water using a small camping cooler with one Swiftech radiator plus a heater core from a Chevy van connected into the loop then placed at the bottom of the cooler. I add just enough water to cover the rads. then add 20# of ice. I fashioned a foam rubber seal to close the area around the cooling hoses when the lid is closed as far as possible. If I bench test the i7 with high voltage setting the ice lasts about 5-6 hours.
I tested 3DMark06 a little more today mostly with HT enabled to see if the lower CPU temp would help, which it did. I also gained a little in Super Pi.

I thought you wanted a detailed walkthrough not only the bios feature
I'm no raid expert, so I thought it would be nice to make a new thread with some of the PROs in raid helping us out, sry if you thought otherwise
My information is that for speeds over 1600MHz, QPI=1.5v should be used.
It is changed automatically with XMP profile. I run mine @ 1.5 no problem.![]()

Thanks for trying it out Blaxtr3m3. I guess the strain is on the IMC itself whether it be 6 Gig(3 sticks) or 12 Gig(6 sticks). Anyway still looking for a good water cooling setup. Anyone have any suggestions? Thanks in advance.

Hi Guys
Great thread, I just got my Corsair Dominator GT 2000 Mhz, 8,8,8,24.
Can somebody please tell me what QPI/DRAM and DRAM BUS voltage they run for 2000Mhz+ on RAM with these?
I Wondered when I use the X.M.P profile the QPI/DRAM voltage is set to 1.6000v + DRAM BUS voltage is set to 1.650v (is that not very high?)
What would you guys suggest: Run high CPU clock like 4,5 Ghz at 1765 mhz RAM (7,7,7,20) or 4,0 Ghz at 2005Mhz RAM (8,8,8,24)?

Hi All,
Neewbie Here, & newbie to all this kinda stuff
Got the rig up & running around 2 weeks ago now & after reading all the pages here on the forum...got it to 4.2ghz....had some issues with screen freeze & BSOD but since found a bad stick of RAM
so now running on 4gb...Vista 64...everything flying....
The one problem I seem to have and can't find anyone else with this anomalie....when the rig is off ( shutdown state )....the ROG Light on the Mobo keeps flashing on & off ( fading in & out ) very slowly every 4 - 5 secs or so..
Anyone else having this problem......or just me....exactly the same with 3 diff Bios versions...now running 1502
