UnOfficial Asus Rampage II Extreme Thread

I got a weird issue, I set my corsair dominator 1600s manually to 8-8-8-20 1n settings in bios and 1.38 qpi and 1.576 for dram. If I go any higher than 1.6v on dram I lose 2 gigs out of the 6. But anything under 1.6v dram its all 6 gigs and runs everything all day long. What is up with that? I left everything else at stock speeds. Only things changed are, qpi voltage, dram voltage, I set the uclk to 3200 and qpi to 6400.

Seen this before, don't quite know why that happens. I'd suspect something funky with the IMC.

Either way, you are not the only one with this issue. Luckily, there is really no need to set the DRAM voltage past 1.65V ever so you should be good.

Thats good to know, I kinda figured I'm not the only one, so far so good this system is more stable than some of the others I have used.

I've got a situation that has me stumped so I need some help or input from everyone here. I've been playing with the adjustments on the board for about a week and if I run the BLCK past 195 I can get it to post all the way up to 219 but when I place it under load at 206,208,216, or 219 the system shuts down within 10-20 minutes as if it is overheating. I am montioring the temps and haven't seen cpu temps over 68 and nb,sb temps that go over 50.

I have adjusted all the various voltages in trying to get stability but it is alusive. I've run cpu to 1.45 and it will read up to 1.48, QPI to 1.425 but I've seen AUTO readings to 1.47, DRAM is at 1.65, I've even tried adjusting IOH, ICH and pushed those to 1.12 looking for the stability that I'm not getting. After the shutdowns the board will reboot itself after around 5 minutes and post fine at the settings used going all the way to windows and then I start over, if I load it same thing happens and if I make some adjustment reboot and then load it I end up with a shutdown anyway. I can't figure out what would be causing a thermal shutdown because readings from Real Temp or Asus Probe are all in an acceptable range that shouldn't cause a thermal shutdown---help...........
