Hequaqua Well think I'm done until I upgrade....lol

Here are my current timings(Patriot Viper only) with TM5 results(1usmus 20 cycles and I changed the Extreme1 anta777 from 3 cycles to 4)



HCI 800%



Ryzen Master



Here is where I've been logging my results.....32gb testing with the Trident Z and Viper Kits. Some 16gb as well. The Trident numbers were from a while back, I may retest those. After several timing changes I then tested the current timings across 4 tests three times then averaged and rounded.

Here is the link for those interested:
Trident Z/Patriot Viper Mem Testing

I could maybe squeeze a bit more out, but I don't want to touch voltages on the ram....I'm odd that way.....lol I'm not sure what I'll do with the Trident Z Kit atm. I have a back-up rig that I could put them in....but it runs fine with the cheap set that's in there.

Anyway, thanks to those who've helped, especially 1usmus and Veii.

OmarAj I tried @Veii try settings and got best latency so far for me thanks for all the help and explanation.

20 cycle TM5 no error
Im getting latency 62.6 when per ccx overclock
Do you think I can tighten it a bit more?

Also tried this in both of my x570 mobo Gigabyte Elite crackling windows sound if Vddg less than 1050, Msi Unify Vddg 975 works great.
The x570 Elite cant do Gdm off with no Error for me, need to use ClkDrvStren 60 but getting stutter when gaming(not 100% sure if its widows or the board)
Just wanted to share my experience

i found the problem

after a restart, when the game is run for the first time, game stutters randomly (both in game, and in the benchmark)

after completing a run, the second run does not stutter

i remembered messing up the video recording in the first run for non tweaked timings, actually two times... after running the benchmark for two times, it seems game created shader caches so it didnt stutter in following benchs

but for tweaked timings, i managed to do it on the first try, hence the stutters (silly me )

i replicated the phenomenon and restarted my pc to re-run the benchmark and weirdly, it really did stutter like in the video (i couldnt see it weirdly)

after running it again, it ran smoothly, just like the non tweaked one;

i better update the video i guess...


and extra; 1st run with non tweaked timings, visible stutters just like the original video is present, due to shader caches are being compiled again, probably (having some problems on that end with nvidia for last drivers )


i hope this clears the confusion

however i will make an updated video where both of them is clear and fully shader-compiled

I present this performance subtiming comparison video for the sake of them.

Thanks to their insight and tightened timings, performance uplift can be openly observed on this benchmark.

Have a good day!

special remark: volumetric clouds are left on low because it's a hugely gpu bound setting and i have gtx 1080 in my hands so

GoforceReloaded I'm currently "stable" with this :

I did 2 TM5 with 20 cycles, i bumped CAD_BUS ClkDrv to 40 ohm and lowered the voltage to 1.48V.



I tried GDM off 1T, with CAD_BUS ClkDrv 24, gave me lots of errors on memtest86, then bumped to 30, 40 and even 60. (i had less errors with each steps but still had errors with it at 60, did not try 120)

I did not run kahru ramtest for 10h+ yet. (passed 1h with 28800mb)

I don't think my ram can do CL14 at 3800mhz, even at 1.500V, tested few times with a lot of errors.

opethdisciple The last good version of this tool was 1.7.0. 1.7.3 gives me noticeable worse timings and membench score.

Gokhan Karaman Greetings to all. First of all I want to thank you. Thanks to the shared successful results, Rams 2933 Mhz is working now. My system information:

ASUS ROG STRIX F-Gaming X370 motherboard (5406 BIOS)
HyperX Predator DDR4 3000MHz CL15 1.35V XMP RAM (HX430C15PB2K4/16) 4x4 kit
AMD Ryzen 5 2600 cpu

Nicely done. +rep.

extra note: both of them had some random stutters even though i tried lots of times. it seems like my 5400 RPM harddisk cant cope with this game... it stutters randomly. so, don't take stutters for granted

Oh lol, did I put 0.2ns? I meant from 66.1 to 68 ish, so 2ns. Not sure why I put 0.2ns, sorry. I know that's margin of error.

Both AIDA64 and DRAM Calc tests were run multiple times to check.

I'm done now I think, it's stable, it's far faster than stock. I'm happy.

Thanks for all your help tho
