MVTK z390 Aoru Master with i9900KS 5ghz with 48 ring


XMP:

G Skill TridentZ RGB F4-3733C17-8GTZR

@ 1869 MHz 17-17-17-37 (CL-RCD-RP-RAS) / 54-655-486-300-10-7-45 (RC-RFC1-RFC2-RFC4-RRDL-RRDS-FAW)
auto 1.35v
auto 1.29v IO (seems high)

auto 1.30v SA (also seems high)





I am not a memory expert.
I would like to run this memory at 3800-3900 with a low latency, no extremes.


May anyone provide me with some timings and voltages I can start with?

Gregix RTL/IOL offset little lower? That should boost latency I think. May be wrong though....

After much tweaking I finally have it HCI stable at 4133cl17 and tightened up some of the secondary and tertiary timings to improve bandwidth and latency. Any advice for further tweaks to potentially push this further?

What happens if you raise tcke to 8 or raise trtp to 8? Does latency improve?

Imprezzion 1,5v DRAM isn't high at all lol. I'm many months into running a Vengeance RGB 3466 CL16 B-Die kit at 4200 16-17-17-34-320-2T at 1.556v DRAM and they do just fine. With a 140mm pointed at them they run about 38-42c but don't get unstable at those temps. I turned off the fan once during a HCI run to see how hot they could get before they got unstable. It ran for several hours but around 49c is where they start to fall off and error out so, got a bit of room temp wise.

Even with 30c+ ambients with the A/C running the most they ever saw was 45c and no instability at all.

These sticks passed many months of gaming and a full 12000% HCI run over night.

I do have a second profile saved which is 4133 17-17-17-28-280 @ 1.44v and that gets way less hot and is just a bit more "safe" in general if I ever do run into summer heat issues or instability.

Yeah, I know what you mean. I ran a similar overclock with my G.Skills first to check the temp and get a general idea then swapped them out. They only see mid 30s with the water cooling.

Mems Patriot steel viper 4400C19 working at 4000-15-15-15-32cr2.
They can do 3700 14-14-14-32 cr1 or cr2 too(ramtest done till 2000%), and 3900 14-14-14-32 cr2(ramtest 1000%) but don't know which setting in bios causes stutter in random moments while benchmarking WOTe so had to give up on this.
I guess I had something wrong with my daily runner prior this, ie corsair venegance lpx [email protected] as aida64 latency was 41-42ns area and WOTe scored lower. But they were weird anyway, max boot was 4266 stock/auto while patriots did 4300. No success on changing primaries st that speeds on both though...bad mobo.
Now I need to find lower Vdram, 1,5v for daily use seems bit too high.
Nice
