ASUS P8Z77-V Deluxe

[someone66]

Hello,
i would be greatfull if anybody could help me. I just bought asus p8z77-v deluxe, intel icore 7 3770K and G.SKILL [TridentX] Dual Channel kit 32GB (4x8GB) DDR3-2400 MHz (PC3-19200) 1.65V CL 10-12-12-31-2N Non-ECC Intel XMP. Installed all components, but i get this memory failuere. Mem ok is flashing red and system is not booting. I use Corsair AX850 PSU. What should i do in this case?

Oh the joy of overvolted memory.

You need to get into BIOS somehow and raise the memory voltage from 1.5V to 1.65V. But 1.65V is overvolting the CPU as well and breaks warranty.

The ability to handle large amounts of RAM at high speed varies with ea CPU
Now that the mem controller hub is on the CPU die, running overclocked RAM is unnecessary, unless you are a benchmark numbers fanatic.
Do yourself a favor return the kit for GSkill DDR3 1600 1.5V set @C10

Better than that, the OP might also consider the Samsung 30nm kits, spec'd to run at 1.35V at spec speed:

Now . . . . it's all over the memory and CPU/OC'ing forums in a few threads. The latencies on these are loose at the stock speed, but by bumping up the voltage to the range of 1.45 to 1.50, I'm guessing they'd run at 9-9-9-24. On the other hand, these can clock up to 2133 Mhz at proven latency settings posted in the threads I mentioned, and at about 1.475V.

And -- they are cheap. They're not only cheap, but they're cool -- dispensing with the need for heatspreaders which look "Kool."

Only problem: the kits are 2x4GB and I don't see any 2x8GB kits. In that case, there are G.SKILL 2x8GB kits spec'd to 2133, but at 1.60V or higher. There are also two G.SKILL "Ripjaws" DDR3-1600 kits of 2x8GB, which may run at 1.5V and one of which will run at 9-9-9-something. Lessee . . . . -16GBXL, -16GXM, and also the Sniper -16GSR.

How those will work should depend on the motherboard. In this case, the P8Z77-V Deluxe is a promising bet. I'm running 4x4GB of DDR3-1600 -8GBRL kits @ 1866 10-10-10-28 1T overvolted (unnecessarily) to about 1.52V with VCCIO set to 1.112V. Certainly you could get one of the kits I mentioned to run at stock speed and latencies in a 32GB configuration.

I understand that certain applications give people an unquenchable thirst for more RAM. You need to think about how you'll test it if your settings depart from spec, or even if they don't. It took me 60 hours to complete a thorough test of my double-GBRL kits at the above-spec speed. that doesn't count the two or three less successful tests accumulating another 30 or 40 hours as I tweaked the VCCIO.
