RAM not meeting advertised claims

[Brian Stirling]

I built a new PC in late January for 4K video editing and chose components that would be high in performance and provide room for OCing. To that end I got an x99 board (ASUS x99 Pro / USB 3.1) for a 2011v3 socket CPU that could be overclocked and added an Intel i7-5820K CPU. I then spent some extra money on my RAM by getting 32GB (4x8GB) of G.Skill Ripjaws V Series DDR4 with 3200 speed and 14-14-14-34 timing. I ran the box at default for a week before starting to OC and there were no problems.

Then, I upped the CPU multiplier to 42 to get a make clock of 4.2 GHz and I could have gone further but decided to stay with a modest OC. I then tried upping the RAM speed from the default 2400 but when I got to 2950ish, well below the 3200 spec, the system froze and I had to reset BIOS and start over. I then put the CPU at 42X and stopped the RAM at 2850ish and all was well for a time but once again it locked up and I've now had to down-clock the RAM to 2400 -- the default. I could probably increase it a bit but I need stability and can't waste time constantly resetting BIOS and starting over.

Suffice it to say I'm more than a little pissed that the RAM I spent extra money on isn't performing anywhere near the advertised performance. I didn't expect to be able to OC the RAM but certainly didn't expect it to under perform the advertised speed by so much. I'm not sure what my recourse is but I'm not happy!

I am not inclined to give G.Skill one more penny ever!

Drop the OC, enable MCE instead, run the RAM at the highest XMP profile it has. If that works, than the mobo can't take all those dense sticks without more volts. If anything I'd blame Asus.

GSkill has always been one of the highest performing RAM sets I've ever used.

Have always been able to OC any set I've had.

I would doubt it is the sticks, but got me, I guess I'm still using an X58 OCing an X5680 on GSkill 1336's.

2011 memory controller is not very strong extra vtt may help
but higher speeds even if you can get them may not be quicker

you may find 2666 with the timings as tight as you can get them to perform best with that platform
good thing is the samsung chips on that ram tighten up nicely

Just to make sure, did you set RAM voltage to the required 1.35V when going for 3200Mhz?
