**WANT 8GB 2400MHz FOR AS LITTLE AS £59.99 Inc. VAT? - THEN CHECK THIS THREAD OUT!!** (MV-3V4G3D/US)

I don't trust Prime95 for memory testing. I only test ram with memtest, Prime95 won't always find the memory errors in my experience.

2133Mhz should easily boot at 1.6V 9-11-11-24 1T 128 TRFC try 1.1V VTT shouldn't need more. Tune down the settings and volts from there, but I really recommend using a new version of memtest P95 isn't reliable enough. I had my system stress for 10 hours or so, but in games I would get memory errors, after using memtest and relaxing my mid timings the memory was stable.

9-11-11-21 was easily achievable for me at 1.5V I doubt your ram is that much different.

P8P67 PRO BIOS 3207
1.Improve system stability.
2.Improve memory compatibility.
3.Support new CPUs. Please refer to our website at: http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us
* Enable support for Intel Next Gen 22nm Processor E1 stepping MP version CPU.

*Please update Bios twice when update from previous Bios version, then need CLRTC.

Make sure you are on this BIOS. I had to update the BIOS on my Gigabyte board to run well with this ram, it let me lower the voltage from 1.65V to 1.5V.

On latest BIOS.

Thanks for the thoughts but in my experience the opposite of what you are saying is true. IBT, memtest etc was all fully stable, but I got a couple of BSOD's out of the blue. Tried P95 and sure enough, errors...
 
That's strange, thought I would mention BIOS as haven't really read through all the old posts thoroughly enough.

Perhaps the problem with memtest/IBT stability could be that the voltages are dropping while in Prime95 load? I set my DDR Load Line Calibration to maximum so that it doesn't drop, I also keep an eye on the VTT during load to make sure it's not dropping, I let mine increase at load from 1.06 to 1.07V.

IBT tends to make my system draw more voltage out of everything, Prime95 tends to not use as much so I never seem to have IBT stability problems.

Good luck with your ram, I noticed no difference going from 9-10's to 9-11's apart from a few numbers on the benchmarks.

You're not wrong there!!

I just use IBT as a "how hot can this get" and "what're my voltages under load" tool now.
In terms of stability, it's vague because it really could be anything/everything. Nothing will ever, EVER, stress it to that much, with that heat.
Prime95, regardless of it's age, i find better suited.
 
try a little steeper incline in timings - I got better results- for example 9-11-11-11

I used to try 9-10-10, 10-11-11 etc to not such good result

currently running 2200, 9-11-11-24, 1T @1.575V, and thats with 16gig
