Please guys... Would be great to sub only with timings visible.

It's all about playing with the os

zen timings ? or what do you mean german panzer

Yes sir

Compo is up: https://hwbot.org/competition/superpi32LLCAMDzen/stage/5160_superpi_-_32m_with_benchmate

Great to see that this is taking off, be with you soon ?

and new Record by AMD again 4:42 !!!

Next step is 4k mem with 2k fclock... But there seems to be no way to run it like that actually

Very good Daniel, I hope, u joined with this to the competition page (I must check it)

 

Safedisk did also a little betetr score and he is focusing at 4m 3xs time

Jack up your PLL voltage to about 2.1v. Benching only........do not take this advice anyone running 24/7.........

High pll buys you about 200 mhz more mem clocks linked. without it the chVIII non dark is capped at 3800/1900. If you experience slowdown crank it till you don't....... Board choice seems to matter alot as to how high the fclk can go linked to mem, as long as the vendors aren't already playing games with pll you should be able to gain 200 mem/100 fabric.

Hi, I also have issues with 3933 Mem clock with CVIII Impact Bios 3003. The board goes in something like slow mode. With 4000 run fine. Did anyone have idea is it a Bios related? Also which Bios is best for Pi 32M on Impact? 

Still can't understand why board goes in slow mode with certain mem multiplayers:

 

 

Otherwise very happy with the board. Pi 32M 2x8GB DDR4@3800MHz 11-11-9-9-21-29-1T

My guess would be aggressive error correction. 2000 is not really any more stable than 3933 or 3966 all produce whea errors when not cutting OS memory down via maxmem. 3800 and lower is perfectly fine if there is no post hole which apparently even on DARK my 5900 has at 3800 with 07 post code. 3800+ boots fine but wheas.

@OClockDoccan you do tCWL 9, tWRRD 1, lower tWTR L/S?

Also does higher ProcODT have any affect on time?

Shure, I know the mem is unstable, but same settings works fine for 4000 and even 4066. That is why supposed it is BIOS issue.

tCWL 9 is no go,  tWRRD 1 is fine, but don`t think it`s faster,   tWTR L/S=3/8 lowest possible for me. I don`t think  ProcODT has direct affect on time, may be stability issue affecting time.

@OClockDocgotcha. Please submit score to the HWBot competition, very nice result!

5min 41sec 775ms That is also mine.

3/8 used to work better for me on R1 as well. Not sure if your sticks can do it but 10-9-9 showed a lot of promise in the past, don't bother with cas 9 though it was slower than c10. dropping twcl -2 of CL is an intel thing. AMD likes them =.

Honestly I ran some aggressive settings the other night vs my daily mem timings. I'm not seeing anything spectacular.

100 mhz is worth 15 secs on avg. im doing 6:00 at 4850mhz on prime stable settings and 6:15 and 4750mhz. Honestly the times im seeing are where they are supposed to be for the cpu speed and the memory tuning gains are like pulling teeth for any gains.

I see what you meant about certain dividers. fwiw at least yours can boot. 5900x boots 3733, 07 hang @ 3800, boot 3866 all the way to 4066 so lol..... That's on the dark but my 5800x is fine......

 

So is new AMD platform with new cpus allow full unlocked memory sub timings in bios?

Yeah I’ve not ran no ddr4 AMD so didn’t know if it was still the same as early release....good to know it’s all unlocked now 

 

thanks mate

@OClockDocCan you do some 4.5g runs with your 4133c12 settings? I'd like to get a feel for how far behind I am, but my CPU can't do 5g single core on ambient.

Some improvement with tFAW=6. Strange, because it shouldn't  be possible.

Cool, I need it try it finally, 5950X is inside

Everyone, hello.
I'd like to challenge SuperPI 32M in Ryzen, too.
A problem wonders about whether possessed 3600XT can reach 5G.
When whether it's invalid does multi-threading, shall the one I can reach go out?
