hi i run a z370 tuf plus gaming board, 8700k, and 16gb gskill tridentz 4000mhz rated speed ram, i just cant get sorted with it, i have used xmp which for the most part is unstable, so i don't bother with xmp, so i set ram to 3200mhz stable, noticed today the voltage on the ram is 1.5v which i believe is considered to high because the boards auto voltage is to generous, i cannot find anywhere to adjust the voltage myself as there is a whole book on timings and voltages in bios, so i found oc tuner 1 and tried that, bios now says xmp 4000mhz enabled but with ram @3200 @1.35v (much better voltage) and also cpu slight enhancement, sorry but i am a bit lost with what is actually happening, is it on xmp but at best speed or something, if anybody can tell me in simple terms i would be very grateful thanks...
memory speed confused

It might be rated at 4000mhz but chances are you wont actually be able to achieve it,depends on the cpu's imc,dram voltage and the ram itself
Theres usually a few xmp profiles in the bios you can select the one nearest to 4000mhz,maybe 3800mhz,dram voltage you can use anything upto 1.45v,you should be able to manually set the dram voltage in the bios
Be sure your on latest motherboard bios aswell as it might have improved memory support

Thanks I only have one xmp profile, I have had it stable before @4000mhz but it was with previous bioses, latest one seems unstable again, and why when I overclock CPU the higher it goes the less ram speed I get, I wish I new what was happening, some people get 5.2ghz on 8700k with 4ghz+ ram? Is that the silicone lottery people go on about...I did hear that overclocking the CPU and the imc at the same time isn't a good thing....
The ram works @3200 great and can work at 4000mhz but nothing in between oddly could that be to do with voltage, if I add voltage to the ram is there a chance it would work at say 3600mhz, but then why doesn't the board add volts itself when I select a speed, and I don't suppose you could tell me where to find the ram voltage at all...
hi i set xmp which is 4000mhz and then just reduced the memory frequency and voilla, i tried 3900 first but then settled on 3800, and i assume its at 1.35 volts as that's what the xmp setting is, having said that though it is still oc the cpu and the ram is also oc....
