ASRock X79/Geil Evo Corsa - Won't boot after memory overclock

post #1 of 4
Thread Starter 
(I think this is the correct forum, if not I apologize)


I recently built a machine with an ASRock X79 Extreme6 mobo and 32GB (4x8GB) Geil Evo Corsa memory set up for quad channel. Everything works great except that when I try to up the memory to it's advertised speed of DDR3-2400 it refuses to boot, and the mobo just pauses with code 69 showing ("North Bridge DXE initialization is started" according to the manual). I've tried using XMP and manually changing the speed/timings and the only thing that works is setting it to DD3-1333 or lower. I've fiddled with just about everything I can change in the BIOS and I'm at a complete loss for what isn't working here.

I tried searching the forum but couldn't find anything similar. Any help with this would be greatly appreciated.



Other info-
Intel i7-3930k
ASRock X79 Extreme6
Geil Evo Corsa 4x8GB advertised as DDR3-2400 (11-12-12-30)
GeForce GTX550Ti
2x Corsair ForceGT 120GB SSD

I doubt it's possible to get 2400mhz running in 4 banks with 8GB sticks. The CPU's memory controller just can't handle that kind of stress. You're going to need to increase the CPU's memory controller voltage- on 1155 it's called VCCIO in BIOS and probably the same thing on 2011. Your best bet would be downclock it to 1866mhz or possibly 2133mhz with tighter timings.

I tried removing all but one stick, upping the voltages a little, and settings it to 1600. Same result. I have no idea whats going on, I've never had this much trouble before.. ugh

I have the same problem with the TEAM GROUP memory that I bought. I went to a LANfest recently and I talked to some Intel guys, they said that the "memory controller on the CPU is not able to handle the addition voltage on my particular chip". Just seems like we're SOL with our chips not being able to handle that addition voltage. It was fixed for a lot of people just bumping the VCCIO up. We can either try to get a new chip and hope the new one clocks better or we just have to deal with slower RAM. I have the same CPU as you.
