Check the Samsung 30nm thread in Intel Memory, people are doing some amazing overclocks with them.

Thanks to everyone that recommended the Samsung 30nm thumb.gif I may have solved my relatively low 3dMark11 Physics score problem. With my crappy G-Skill RAM and 3930k @ 4.6Ghz, Physics was 12,930. With the Samsung 30nm, running dual-channel, 2133mhz 9-10-10-24 1T, score was 14,600.

I can't recommend the Samsung enough thumb.gif What's the max voltage everyone has been using for them? Recommended is 1.5v I believe, but many people go higher for quick bench runs?

The latencies don't matter as much as the speed. You can run those sammies at 2400 11/11/11/28/1t at 1.53v. When I run them at 2133, I use 1.45v.

Been messing around with it and I can't get it stable at 2400mhz for the life of me. It will boot and then crash when opening a program. I've had both of the DRAM voltages up to 1.58v and still couldn't open more than a program or 2 before getting the blue screen. Any other voltages/settings I can look to? I been using the guide on here, and have voltages like VCCSA, CPU PLL, and a few others turned up a bit, but that didn't seem to help either, even with loose timings.

I've been testing the RAM in 3dMark11 to measure point-differences, since I'm hoping the RAM is why my scores are so far below average. I would assume 3dMark11 doesn't benefit much from lower latencies?

Also, not seeing any throttling @ 4.6Ghz. Testing with Prime for a little while, max core temp was 80C, CPUpackage got up to 67C. Does the CPUpackage temp matter more? Does it throttle at 91C, or a lower temp than that? Also, I think the board's VRMs are in better shape now. I installed an 80mm fan hanging off the back of the HDD bays blowing in their direction, and also the lower fans on the H100 rad are sitting less than an inch from the VRM heatsink, so their taking much of the hot air away I would assume.

I couldn't get my set stable at 2400 either, and the sets didn't respond at all to voltage increases. Perfectly happy with 2133 @ 1.405V. I think it may be luck of the draw.

Yeah it's not responding to voltage increases at all. But yeah I guess 2133mhz 9-10-10-24 1T is something I should be satisfied with. I still have to start lowering voltages one at a time to get everything as efficient as possible.

PS- That little guy scares me too biggrin.gif

Glad to hear your VRMs are getting some more airflow. From what I have seen, latencies don't effect 3Dmark all that much, nothing outside the variance of normal point differences between runs.

Thanks again for all the help, +rep. So assuming the VRMs are ok, is CPUpackage temp what causes a throttle at 91C? Or do the cores have anything to do with it? My core temps will get up into the high 70Cs but CPU temp will be a solid 67C.
