Discussion Zen 5 Builders thread

The Maxxmem2 score is good. But in Rapydmark, it seems the test "Hash SHA1/256/512 MD4/5 CRC32 RIPEMD160 (512 bytes)" is giving your 9950X quite a bit of trouble. Are you sure you are on the latest AGESA?

Yes, lates 1.2.0.2.
Bear in mind I'm running my original Windows 10 Pro since at least 5950X, very not fresh at all
I have quite a bit of programs I use, so reinstall is the last thing I want to do this week.

Another thing is, 2vs4 DIMMS and SR DR memory, it can have quite an impact on some tests.

Anyway, one more test for today:


As seen from OpenGL test, tweaked timings and 103MHz FCLK gives desired results. This is best for gaming I can get from my memory kit keeping it stable. CL28 is a no-go, 6400 is also a no go even at 1.5V, simply I need new 2x24GB kit, something similar to what @Det0x is using ...

Good improvement!

However, something is still a bit off with the Hash test in Rapydmark. For reference, a stock 7950X with DDR5-6400 is able to finish it in about 30 secs while my Zen 2 128 thread Epyc takes about the same time as your 9950X. I think your 9950X should be able to complete this test in 28 secs or less if some mysterious setting is set right.

Never thought of doing that. You are a genius!

For some reason, I feel 8 threads would be fastest on my PC, I just can't find a way to change that in this program. I will try disabling HT tomorrow, see what that does to this subtest.
