Asus Z490 stuff

Rule of thumb for VTT on auto is HALF of vdimm. You basically undervolted it there with 0.75v (making it equivalent to 1.5vdimm) with your 1.53vdimm. Id recommend something like 0.79vtt

By increasing your tertiary timings a bit more it will help boost read-write copy bandwidths a fair bit.

Attachment 87736

Im aware of that but like I said, no difference on this voltage, when increase o/i on 11 it reduces my latency with 2ms. I also crashed when tried to upload these screens with these timings. I already have tested the 3rds but wanted to give you screenshots. it doesnt giveme any indication of improvement. I can lower tRFC to 260-280 but introduces instability. its fine in gaming though. BTW on 4400mhz Id imagine I would get similar read-writes. Your copys are good.

ps. IDK why this forum has problem with my screenshots?!

Try lowering:
TRDRD_DD/DR to 5
TWRRD_DD/DR to 5

*since you are running 8gb DIMM's they will be sr so really DR won't do anything (i'd put a 0 to it) but DD will.

For stability and there is usually read bandwidth regression when going too low of a value for:

TWRWR_SG/DR/DD should be 7 not 6

Sorry, what are you referring to regarding "when increase o/i on 11 it reduces my latency with 2ms."

I really wish I could reduce my latency abit further and or by running tighter primaries but I can't seem to get stability. I'm not really willing to go to a crazy level of voltages I've seen some people do with vdimm/sa/io perhaps I'm stuck due to my IMC on the 10850k.

TRDRD 5 gives me bluesscreen, TWRWR 7 doesnt give me an improvement. I know what im doing. On that voltage, even though I can lower some of the timings I dont have improvement, at least in Aida. On 4100-4200mhz I can lower them & gain performance but not on 4300

that's correct alder lake is a whole new architecture/processing fabrication. Best to hold out for the end of the year and splash big on a new system and ddr5.

+1 on holding out till end of the year.

I'll be skipping Intel Z590 platform.

Working on new AMD Ryzen 9 5900X, Asus ROG Crosshair VIII Dark Hero build now,.. been a few years since I have messed with AMD BIOS, using CTR 2.0 is proving to be an interesting experience. https://www.igorslab.de/en/clock-tun...d-much-more/2/

I wonder if any folks will be moving over to the Z490/Z590 forum? I just ran across it the other day..

TRDRD 5 gives me bluesscreen

Yupp, by changing

tRDRD_dd 4 -> 5
tRDRD_dg 6 -> 5
tWRRD_dr 0 -> 5
tWRWR_dr 0 -> 7

I got my PC into a state in which it wouldn't even let me enter bios anymore. It already had these tho:

tWRWR_sg (7)
tWRWR_dd (7)
tWRWR_sg (7)
tWRRD_dd (5)

I am about 99% sure that I put in the same RAM settings. The results were consistent before; it could be that it's the BIOS, even though that one doesn't contain system performance as an update. This is from UserBenchmark.

Don't know why I'm here you guys are way out of my league! ie beginner

You missed all the fun last year playing with these mobos and bios, lol

All right i got a weird one, maybe you guys can help me understand whats going on.
10700k, + Strix-E, core ration is set to AI mode and the settings i set it to allow it to boost to 4.8ghz all core 4.9 on 3 cores and 5.1 on 1 core
what i just noticed is that when a single core load happens (ex i've been using prime95 non avx test on 1 thread) that the cpu doesn't boost to 5.1 it sticks at 4.8ghz
now if i close off Discord and Steam then the clock jumps up to 5.1
Is it that somehow those 2 apps are putting a load on the cpu so it detects it as a all core load instead of single core?
Also tested with discord and steam off and with just Google Chrome (since it likes to spawn a bunch or processes) and that seems to boost to 5.1
