DDR4 and XMP

fantoc1 · 29 Sep 2015 at 18:56

Hi guys,

Just looking for an advice since my GFX needs to be RMAed I can spend some time with this. Bought DDR4 3000mhz but noticed in bios it runs as 2144 mhz. I looked for the XMP profiling in bios and enabled it which changed the settings to 3000mgz however the system did not even boot up and I got an error ''no ram installed''. I am not very familiar with this but I am guessing that I need set the ram somehow after the XMP is enabled? Any advice would be great to get the ram going since I invested in it. I am running skylake btw so it should benefit a bit.

Thx,
Tom

Reset CMOS, then using trial and error see what works

I'm the same i bought 3000mhz RAM and the computer doesn't post when i set it to that speed.

Try with 1.35v for your ram, 1.175v SA, 1.15v IO, check that your ram speed is at 3000 before you save and exit.

Do we even know what platform or board

No idea what board but running skylake

mobo asus max 8 hero with skylake. will give that try tonight but its weird

I got mine running at 2995mhz/3000mhz
I'm on a asus gaming pro skylake
i set my ram to 2900mhz in the bios then slowly using the - + keys put up the BCLK frequency.
from 100mhz to 103.25mhz which gave me the 2995mhz RAM.
BUT the POST half works and windows came up with a BSOD on the first boot.
After that its been running fine.
Memtest shows no errors.
odd i know O_o;;

Check and see if you can change the ram voltage as on my x99 board I could set the XMP profile but the ram volts were stuck and never changed even when I'd dry it manually. Rma'd the mobo and ocuk tested it and replaced it and the new board had worked boo issues yet

this was x99 but still with having a look if the ram volts are behaving

Memtest won't show you much on this platform other than if you've a dead stick or not, plus it's not indicative of what is happening when the system is failing training, because when the system is passing training it is likely stable.

Change FCLK (System Agent Clock) to 800Mhz manually. This option is under Tweakers paradise and helped with a lot of training issues for me when pushing memory frequency above 3200. You may need to tune DRAM and System Agent voltages also.
