Just got done setting the final 24/7 clocks for my new Core i7 Rig. Went caseless on this one Sadly, I hit a pretty hard wall at 214 BCLK and clouldn't even think of getting stable until 211. I was testing at 215-218 BCLK, but needed suicide voltage to do it

I'm driving the pump and radiator fans with a old AT power supply, so as not to draw off my main system PSU.

I added a homemade shroud to the radiator after this pic:


Adding PSU and boot HDD


Final Clocks & voltages for 24/7: With my DMM, vDIMM measures 1.66 with these settings, and vCORE 1.48. Most volts are set to stock. Messing with the PLL voltages only seemed to cause more instablitiy for me.

try messing with 21 or 19x multipliers. I find that 20x multi is harder to get stable than those

Hi again! I just sort of got back into the swing of things with my 6 month system based on core i7 and want to get some refferances on some basic OC profiles to start with.

System is ASUS RAMPAGE II GENE with i7920 DO stepping batch 397B85 Date not Known but replaced it only last month. OCZ Platinums 7-7-7-24 2x 2g 1600 and a new pair of Curucial Ballistics again same type but 8-8-8-24 on the way for looks but can use either. hoping to get DDR 1800 out of one of these kits . I will try my best with my bad eyes to back trak the hundreds of post in the last year but if anybdy is cool enough to link me to your post or others where I can read more that would be cool. I am open to sample profiles for refferance starting points.

Thankx in advance!
