Issues with XMP profiles with Kingston Savage DDR4

post #1 of 5
Thread Starter 
Hi all, i have assembled my new-ish PC today and i have some issues with RAM.

I have Kingston Savage DDR4 2800Mhz 2x8gb. HX428C14SB2K2/16

At stock speed of 2133Mhz i get this transfer rates in Aida64


but when i load XMP profile 2666 or 2800Mhz, i get this


which is quite a bit lower then 2133Mhz. Its actually slower then my previous 1866Mhz DDR3 Patriot Viper3

Is it an issue with RAM or motherboard ( Gigabyte z170-gaming k3 , supports up to 3466Mhz ) or something else ? I tested the RAM when CPU was at stock, same results.

From what i could find about DDR4, read/write speeds at 2800Mhz should be around 40k MB/s

look at the SPD section in AIDA64 under mother board.

Find the right profile, and set all the timings manually.

Sometimes boards set thing very conservative (loose)

Tnx for the quick reply, i figured out what was the problem.

Timings were ok, same as advertised on Kingston site. Issue was with " Memory Enhancement Settings" which i noticed only after entering bios 10th time. By default it was set at enhanced stability, but after setting it to enhanced performance numbers jumped to 40k MB/s

Nice.. dropped your latency quite a bit too.

Glad to see you worked it out
