Thanks for sharing your issue and solution.

Solved my DDR5 4800 vs 6000 ram mystery. With low profile cooler, my system was getting to tjmax limit (85C) quickly and power was throttled to not go any higher. At 6000 mt, ram requires 1.35V instead of 1.1V, which I think translated to extra heat, and made it throttle sooner. I replaced the cooler with stock Wraith Prism, nice bump in hashrate, and then switching to 6000 mt showed real benefit. These measurements were taken 10 minutes after mining started.

Low Profile cooler 4800 AGESA, room temp 69F
Tccd1      85C:     12,085 hashrate / 90 watts = 134.3

Wraith Prism 4800 AGESA, room temp 72F
Tccd1      64C:     14,802 hashrate / 125 watts = 118.4

Wraith Prism 6000 Aggressive, room temp 72F
Tccd1      64C:     15,660 hashrate / 131 watts = 119.5

Hi there...

It does seem pretty much specific to xmrig, maybe adjusting your config in xmrig would help, sorry I cant be of more help....]]> Sat, 02 Mar 2024 19:18:19 +0000 https://forum.asrock.com/forum_posts.asp?TID=30999&PID=113178&title=a620-w-7900-need-5200-dram-profile-setting#113178 https://forum.asrock.com/forum_posts.asp?TID=30999&PID=113148&title=a620-w-7900-need-5200-dram-profile-setting#113148 Author: FiatDemise

I got a suggestion to run a memory bandwidth test. I'm running Ubuntu, found this program called mbw.
https://unix.stackexchange.com/questions/32517/how-can-i-observe-memory-bandwidth

Running that showed much better results for 6000 vs 4800, values like 21k vs 17k. So, maybe I don't have a ram/mobo issue, but something more specific to xmrig.]]> Sat, 02 Mar 2024 10:03:14 +0000 https://forum.asrock.com/forum_posts.asp?TID=30999&PID=113148&title=a620-w-7900-need-5200-dram-profile-setting#113148 https://forum.asrock.com/forum_posts.asp?TID=30999&PID=113084&title=a620-w-7900-need-5200-dram-profile-setting#113084 Author: Katana1074

Don't think you can upload pictures to the forum, If you change infinity fabric speeds, you will need to adjust your voltages, I would keep testing, but it can be very long winded, I run ddr5 6400mt, with 2133 fclk (it gives me the most consistent results)...]]> Fri, 01 Mar 2024 16:41:33 +0000 https://forum.asrock.com/forum_posts.asp?TID=30999&PID=113084&title=a620-w-7900-need-5200-dram-profile-setting#113084 https://forum.asrock.com/forum_posts.asp?TID=30999&PID=113082&title=a620-w-7900-need-5200-dram-profile-setting#113082 Author: FiatDemise

Tried the Infinity Fabric Frequency at 2033, with Expo 6000 Aggressive, got 6k-12k. That's an improvement, but still not as good as 4800 performance.]]> Fri, 01 Mar 2024 12:16:29 +0000 https://forum.asrock.com/forum_posts.asp?TID=30999&PID=113082&title=a620-w-7900-need-5200-dram-profile-setting#113082 https://forum.asrock.com/forum_posts.asp?TID=30999&PID=113081&title=a620-w-7900-need-5200-dram-profile-setting#113081 Author: FiatDemise

Is there a way to upload an image in this forum? Would be much faster if I could share pictures of my bios settings.

Anyway, for UCLK DIV1 MODE I have UCLK = MEMCLK
and for Infinity Fabric Frequency I have 2000 MHz.

Is FCLK = Infinity Fabric Frequency? And I should try setting that to 2033?

Hi there...

There's something else going on then you get less performance at 6000mt, have you set your infinity fabric speed ? start at UCLK:MEMCLK 1:1 and FCLK 2033....]]> Fri, 01 Mar 2024 03:48:38 +0000 https://forum.asrock.com/forum_posts.asp?TID=30999&PID=113077&title=a620-w-7900-need-5200-dram-profile-setting#113077 https://forum.asrock.com/forum_posts.asp?TID=30999&PID=113054&title=a620-w-7900-need-5200-dram-profile-setting#113054 Author: FiatDemise

I tried that, but got worse performance. I suspect the 6000mt performance being worse than 4800mt performance was due to the 6000mt speed not being officially supported.

I use XMRig to mine Monero. With ram at 4800 and AGESA default settings, I get a hashrate of 10k-13k. At Expo 6000 AGESA default I get like 6k-11k. At Expo 6000 Aggressive I get like 5k-10k.

Hi There..

Amd state the maximum official speed supported is ddr5 5200mt, However the sweet spot for amd is ddr5 6000mt, just load the Amd expo profile for ddr5 6000mt...]]> Thu, 29 Feb 2024 16:35:58 +0000 https://forum.asrock.com/forum_posts.asp?TID=30999&PID=113041&title=a620-w-7900-need-5200-dram-profile-setting#113041
