Question About XMP

post #1 of 5
Thread Starter 
I am going to be getting the ASRock Z170 Gaming ITX/AC. On the ASRock website they show the below ram is compatible with my motherboard

http://www.newegg.com/Product/Product.aspx?Item=N82E16820231918&cm_re=F4-3466C16D-8GTZ-_-20-231-918-_-Product


Since its overclock ram and not the base model will i have to manually set it or will XMP work when setting the ram for that motherboard?


Will i have any problems? Or will XMP be fine ?

Overclock ram? Not the base model? What do you mean?

 

Yeah, you will have to make sure to set the clock speed and timings (and probably the voltage) manually somehow. Whether you do it manually or using XMP is up to you, depending on what works best. If you don't, then I believe it will just be set to 1600 MHz.

I heard XMP sets the timings and all that is stored on the RAM and you won't have to change anything.

Yeah, but sometimes that doesn't give you the results that you want. It seems that it's not exactly a perfect system sometimes.

XMP will set your first, second and third timings, and also the voltage and frequency. (and maybe fsb also?)

I have a 2400mhz quad channel kit, that i sometimes run at 2133mhz with tighter timings (not a huge difference either way besides load on the IMC).

I've found that manually setting my first timings to that of the XMP profile, and leaving the second and third timings up to my asus rampage IV BE motherboard results in a far more stable system.
Also, using the xmp profile for 2400mhz with 10-12-12-31-2T timings, and 2133 with 9-11-11-28-2T timings results in virtually the same benchmark results, but with my cpu (4930K), if i try to run 4.3ghz or higher with 2400mhz frequency (regardless of XMP or not), my vtt voltage goes up to about 1.3V (auto set by motherboard - which is above recommendations for this cpu).

TL;DR
Basically I can get similar performance from the RAM and higher o/c on my cpu by avoiding XMP, due to the quality of my IMC, ie. my system performs better/more stable when i ignore XMP.
