flanker Posted December 11, 2020 Posted December 11, 2020 and new Record by AMD again 4:42 !!! https://hwbot.org/submission/4625069_safedisk_superpi___32m_ryzen_9_5900x_4min_42sec_781ms Quote
Dancop Posted December 13, 2020 Posted December 13, 2020 Next step is 4k mem with 2k fclock... But there seems to be no way to run it like that actually 4 Quote
flanker Posted December 13, 2020 Posted December 13, 2020 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 https://hwbot.org/submission/4627290_safedisk_superpi___32m_ryzen_9_5900x_4min_41sec_361ms Quote

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.

OClockDoc Posted December 15, 2020 Posted December 15, 2020 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? Quote
OClockDoc Posted December 21, 2020 Posted December 21, 2020 (edited) 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 Edited December 21, 2020 by OClockDoc 2 Quote

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. 2 Quote
SparkysAdventure Posted December 21, 2020 Posted December 21, 2020 @OClockDoccan you do tCWL 9, tWRRD 1, lower tWTR L/S? Also does higher ProcODT have any affect on time? Quote

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.

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......

Bullant Posted December 24, 2020 Posted December 24, 2020 So is new AMD platform with new cpus allow full unlocked memory sub timings in bios? Quote

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 Edited December 24, 2020 by Bullant Quote
SparkysAdventure Posted January 19, 2021 Posted January 19, 2021 @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. Quote

Broken APEX49 Posted February 25, 2021 Posted February 25, 2021 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? Quote
