New 3570k build Vengeance 2133 issues

post #1 of 3
Thread Starter 
Just finished my new Ivy Bridge build w/ an Asus Z77 V-Pro and 4x 4GB Corsair Vengeance 2133MHz and I'm having some problems.

The install came off without a hitch, I chose the X.M.P. profile on the Asus Bios and it instantly recognized the ram and set it to correct speed and timings. However I immediately began having crashes with error codes indicating faulty memory. I ran MemTest86+ and ended up with thousands of errors within a few minutes. Thinking maybe I'd received some faulty RAM, I started pulling sticks and trying them individually. To my surprise, all four sticks passed at 2133 and 1.5v without error. So I mixed it up a bit, trying them in pairs, and in different slots, and was unable to reproduce the issue. So after reinstalling all four sticks I've found that they will run without error together only up to 1866MHz and not beyond. Any faster and I start receiving nonstop errors within a minute or two of starting the test. I've updated the bios to the most recent version, and I tried upping the voltage in increments just to see, but no dice.

Does anyone know why this RAM would operate perfectly individually and in pairs, but not together? I'll admit, I'm new to this, please let me know if there are some settings I should change in order to have better result.

Either way, any help would be greatly appreciated.

This sounds more like configuration issues in the uefi or motherboard not being able to handle all 4 sticks at those speeds in that case could be faulty mobo.

I'm personally hoping it might be solved by changing some UEFI settings. Unfortunately I have no idea what to try. Do you have any suggestions on what I could switch up to perhaps get to the root of this problem? I've tried manually setting the speed, voltage, timings, even loosening the timings a bit, just in case. None of these were successful... Fortunately (or unfortunately for me) there are about 100 other settings that I don't know enough about to change, which could be the culprit.

Maybe someone with greater understanding than I (almost everyone) could lend some advice?
