UnOfficial Asus Rampage II Extreme Thread

[Nuckin_Futs]

Ok, I've dropped ram down to whatever the lowest speed is for that particular bclk and also the uclk so it's double my dram frequency.

I'm now going to raise the bclk and see how far I can push the stock voltage, 1.208, currently sat at 3.9.

I'll test it using small ftts in prime and maybe IBT normal ram use perhaps? Hopefully I'll manage to get to 4.2 then when the cpu is stable I'll push ram upto 1600 and test it all.

I'm not taking ram over 1600 so I always thought I wasn't overclocking before.

Does this sound ok?

You're on the right track so far. As far as the mobo and ram is concerned, we are overclocking even to use DDR1600 since the Jdec standard is like 1066 or 1333 for most modules. So keep in mind as we up the BCLK we need to up a little at a time to other key items like NB/SB, QPI, VTT, and at times even PCI-E freq. I do believe we need to focus on QPI when also trying to run DDR1600. Hopefully others can help add more fact to this part and how much at a time. I am using 1.35 to 1.40 QPI qith DDR1650 1800. Below is a basic settings for a 920 DO @ 200*20 DDR1600. [as set iin BIOS] = active

Voltages
Vcore [1.25625] 1.244 (some may need closer to 1.3v) I have 1 that needs 1.28750 in BIOS

QPI [1.26875] 1.230
IOH core [1.17966] 1.177
