Ivy Bridge Overclocking Guide ► Asus Motherboards - Page 202

post #2011 of 7033
Ok, thanks for the help Dubbed. I'll do that. I've been Priming for 20 minutes now on full load and the 1.65V configuration seems nice N stable.

My concern was that somehow my stable CPU would inadvertently become unstable from the DRAM voltage change, which I'm sure is possible but doesn't seem to be happening here.

I'll post a followup soon.

Ivy can handle DRAM voltages up to 1.75v no problem. High memory overclocks will increase the heat produced by your Ivy chip because the IMC is on the die. You're best plan of action is to find a stable OC on the CPU with RAM at rated speeds and THEN try to overclock your RAM further once your CPU is stable. It's a bad idea to do both at the same time because it becomes more difficult to figure out which component is causing the instability.

I don't think his trying to OC his ram.
think he got confused with the 1.55v that's written in the OP vs his rated ram smile.gif!

Oh okay, how bout them Red Devils today? Sloppy in the 2nd half but a win is a win!!! 7 points clear.

True, but definitely an exciting game!

Yea originally I got CPU OC'd at 4.2 GHz with 1.20V and the RAM at 2133 MHz 1.50V but my RAM is rated at 1.65V which also explains why I couldn't POST when I had it set to 2400 MHz in the first place.

So I setup the CPU OC with 2133 MHz memory speed in place. But I was getting stopped Workers in Prime95, so I the DRAM voltage to the rated 1.65V and low behold, I could run at 2400 MHz. And the CPU OC still seems stable.

Running Prime95 12 hour test to be sure.

So i menage to get stable 102.3 x 44 on offset voltage with -0.005.When its in load i got 1,264v,BUT i need to put LLC on Extreme(100%) or it is not stable.So is it danger to have it on Extreme LLC if voltage reach only 1,264?
Just for the record,if i put LLC on to Very High(75%) voltage reach only 1,230 in load and system is not stable.

Sounds good, tell me how it goes.

Fine example why I tell people to use manual when stress-testing and not offset.

First, change LLC to 75%.
Second, change CPU voltage to Manual 1.25000.
Third, attempt to run prime95 for 12 hours.

What Swag said.
Also, are you using something other than 100.0 for your BCLK?
