P67A-UD4 Memory Questions. How high is your RAM on SB?

post #1 of 5
Thread Starter 
Hello,

So I've been messing with the SB platform now for a couple weeks. I have pretty much been playing with CPU speeds and not messing with the ram. I tried going above 1600mhz, and then had to reflash the bios. It wouldn't boot up until clearing the cmos.

I have Corsair Dominator Gt 2000mhz C8 8-8-8-20 @ 1.65v

I did boot once into windows with the ram @ 1866mhz and 2133mhz. Tried superPi and it would crash. After that, seems like going above 1600mhz wasn't going to work. I'm not sure how strong the IMC is on the P67 setup's yet.

Anyone else here know the trick to getting the ram up higher? I'm on the UD4, so if your using that or something similar, even better.

I should have no problem running my ram @ 1866mhz with 7-7-7-20. It's ran 1940mhz 7-7-7-20 on my i7 950 setup for a few months with no problems. I should be able to get 2133mhz too if I relax the timings to say 9-9-9-24.

What voltage you running the sticks at? You could try adding a little bit more voltage to reach the higher clocks.

It could be that the IMC on your processor might just not be able to handle those speeds while your 950 could.

You could also try upping the QPI voltage, thats where the IMC is.

Im running 1.5v ram on my UD4, maybe the extra voltage is putting a strain on the chip?

What mem speed are you guys hitting?

Anyone stable at 2133?
