It's in the OP in the stress testing section, I believe.

Check my link above if you haven't already. Def the best deal out there IMO. If not, you can pick up Bumblebee's eyebrows for a little more:

Yes! I simply do not understand the thought process behind this. The Samsung UDIMMS went for $80 @ 16 GB, 1.35V, clock like crazy, and actually sit UNDER the RAM clips of a board!
One of the egg reviews:

"Easily overclocked to 2133mhz CL11 at 1.65v."

I would be very interested to know the IC in these.

The samsung low voltage sticks use samsung HYKO ICs. Although they were great price/performance at $40 for a 2 x 4gb kit, they weren't really high end, the same HYKO ICs on a full height PCB can clock considerably higher, they were used for quite a few 2400 & 2600Mhz kits.

Do you have some suggestions of 2x8GB kits that use those ICs? I'm not really having any luck finding a kit worth having.

When i want to run RAM speed over 2133 i need to raise what ? Io?!
post #4375 of 19539
Can you do a step by step for setting up the x264? like what apps to use to open the files and how to work the test headscratch.gif

You should validate RAM stability at stock cpu first

Stock CPU + 2400 MHz RAM = no boot

The IO settings can help out with RAM OC stability, but mainly its going to be coming down to the RAM timings and voltage. Depending on how much of an OC you're trying to get to, you might end up having to increase your VCore or VRIN voltages to accommodate the higher frequency.

And is x264 a better stress test than prime ?

Not all RAM can run fine @2400cas10 1.65v or whatever

It might catch a few things that prime doesn't, but it's certainly true the other way around and probably moreso. Prime is way harder on RAM if you test properly (high priority 6000-7000MB RAM custom blend with rounding and error checking) and probably on other stuff too, maybe uncore. For checking RAM stability, i'd prime at 4ghz core 3.4 uncore (can do at like 1.7vrin, 1.1 vcore 1.1 ring personally np for any stress) and then verify it still works at your max core clock after stability is sorted out there

x264 was more of an actual program that was tricky to stabilize on Haswell compared to some other stuff (that frustrated me when i started to OC) rather than an all inclusive stress test. I don't think there's a good way to do that on Haswell, maybe avx1 prime w/ 7000mb RAM custom blend rounding error checking etcetc for a pass of each fft lengh @ 15 mins each (like 10+ hours) and x264 among other stuff if you want to be hard on the OC
