Hi,

I've been struggling with this issue for a few days. I initially thought it was the ram, but I purchased a second set and have the same issue.

I bought my PC recently and purchased 8 sticks of ram for a total of 32gb (G.Skill 3000mhz DDR4). After a week, I realized I needed more memory, so I ordered and received 64gb (G.Skill 30000mhz DDR4). When I went to install the ram (8 sticks of 8gb), my pc wouldnt boot up at all. I had to clear the cmos, and check out the settings. The 64GB or ram only seems to work at stock 2133mhz speeds, even though the ram is is rated for 3000mhz. Even if I set the ram to 2200-2500mhz I will get past the boot up, but will get a blue screen crash in windows. Beyond 2500mhz I dont get even a boot.

When I remove 4 of the sticks of ram, I can run them at 3000mhz no problem. The issue is when I add the additional 4 sticks.

Additional points:

1) with 4 sticks of ram (32gb total) I run at 3000mhz ram speed, and 4.5ghz CPU speed (36x125mhz)

2) I emailed G.Skill and they recommended I increase the System Agent Voltage, which I tried and it made no difference. I tried 0.300, 0.500, and 0.600 (which it states is the max).

How can I get my 64 gb of G.Skill ram running at 3000mhz?

System Specs:

i7 5960x

ASRock X99 Extreme6 3.1USB

G.Skill RipJaws 4 F4-3000C15Q-32GRBB (2 sets for a total of 64GB)

GTX 970

Corsair AX 860 PSU

Please help!
