The Maximus Formula Thread - Help/OCing/Guide/Rampage conversion

Well, yesterday I received my RMA'd kit of the G.Skill F2-8500CL5D-4GBPK (not bad, I must say, within a week ) so I obviously had to have a go at getting these to run at the same speed as my Ballistix Tracers, namely 1117Mhz..

Started off at 1.94v in the bios with the previously suggested settings (skew, etc.), resulting in a stable rig in memtest at 1066Mhz. Happy as I was that these now finally do run at their rated speed, my initial excitement quickly faded as I noticed that I could not run the sticks any higher than this, despite people's great experience with them here in the forum. I've tried different skew settings, changed Trfc to 55 and even tried with the CPU running at stock. Also upping the voltage to 2.12v real did not allow me to reach any higher speeds, although the errors in memtest did seem to decrease upon increasing the Dram voltage. But I'm a bit weary with upping the voltage on these puppies, how high have people gone before without destroying the sticks?

Also, is there any other setting I could try to get these sticks to run faster, even 1080/1090Mhz I'd be happy with as my Everest benchmark is non too exciting right now, even though I'm on the 0308 Formula bios:



Thanks again for any ideas!

They should do 1080 very easy with settings
Dram static enabled
Clock twister strong
PL 7

advance clock skew 300ps both channels.
TRFC to 55
and set 2.12 in bios if it passes then start lowering dram volts.
your NB volts will play a part 1.47 to start and adjust up from there.
I need 1.51 NB volts for stability.

Mine do 1103MHZ currently and will boot and bench at 1130MHz, trying to get them stable now with some tweaking.
