Title: Z170X-GAMING-3 Memory problem
Post by: sharpnel on December 28, 2015, 06:16:49 am

i've no idea what's going on. my memory read/write/copy dramatically reduces when i use XMP profile or just set the XMP profile manually.

my rig
Z170X-GAMING-3 - BIOS Version :: F3
6700K Stock @1.080v with 212x
G.Skill Ripjaws V 2666Mhz CL15 8GB*2 and Kingston Fury HyperX 2666Mhz CL15 8GB*2 (i tried both and got the same result. *please note that i didn't use both modules at the same time.)
Samsung 850 evo 120gb + 500 2.5'' hard drive + 1TB*2 external hard drives via USB3.0
Sapphire NITRO r9 390 8gb

here are screenshots @2666Mhz XMP Profile (*Both Ripjaws V and Kingston Fury have similar results.)

@2600MHz Manual Settings (too, Ripjaws V and Kingston Fury have similar results.)

Memory Latency : http://puu.sh/mb1k1/f321ea4482.jpg

i tried to overclock my ram to 3000Mhz and the results are similar to 2666Mhz. it seems like the board can't handle anyMHZ beyond XMP profile or i don't know there was something wrong.

at first i think it's the memory module(Kingston) itself that causes the problem so i bought Ripjaws V to test and got the same results.

any ideas?

thanks in advance and sorry for my bad English.

Once they get it fix I would run the memory at stock settings. Look at this thread:
