2400Mhz Memory with Xeon E5 2697v3?

Hardware Overclocking
#1

Hello everyone!
I recently upgraded from an old i7 5820k and 16 gigs corsair RAM to my new old Xeon E5 2697v3 and 64 gigs of SK Hynix ECC glory.

Officially the 2697v3 only supports RAM speeds up to 2133Mhz. My Modules (4x HMA42GR7AFR4N-UH) are 2400MHz ones.
Unfortunately I can’t get them to post on 2400, but I got them running at 2133 with some tighter timings (CL14-14-14-34).

Anyone got some tips or tricks to get them to 2400?

I am on an ASUS X99-E WS on the newest UEFI with a slight -90mV undervolt on the CPU → 2.9Ghz on all-core workload, HT on.

Cinebench score and HWInfo attached.

Thanks for reading :slight_smile: !

My expectation is that running that memory at full speed is not going to work, as the CPU just isn’t capable of handling it. You will have to upgrade to a v4 series to get that.

But I am glad that you got it to work at all - in the past couple of weeks the price difference for 2133 MHz and 2400 MHz RAM has become negligible, and the 2400 MHz sticks are easier to find. Maybe I’ll pick up some for my 2697 v3 rig.

I don’t think you can overclock memory past rated speeds on modern Xeons
