I was seeing 80ns in Ryzen DRAM calc as well. I then dropped the clock to 3600 C14 from 3733 C16 and now latency sits around 68. Havent benched transfer speeds though.


How did you bench your read/copy/write speeds?

parallelparadox Hmm, not sure if it is isolated, updated to F42b, managed to login to windows and all fine. Then restarted PC and looks like the BIOS is gone and Mobo wouldnt boot.


Backup was only F8 and wouldnt boot my 3700X. Biggest hassle to take apart two PC's to get my Mobo living again. Anyone else experience issues when updating? I got a message saying update was successful and all was good until restart.


Though I have updated my backup to F42a, my tower is mounted and it would be a pain to take of mount to restore again if it should go bad again.

Any ideas guys?

EDIT: With Fast or Safe presets. I will post some screen shots later

tsamolotoff SuperIO isn't accurate in its monitoring, so I'd just discard those measurements. Just compare SVI cpu voltage measurments, direct-from-VRM data (IR35204) and SuperIO voltages, first two are close to the ground truth, second one... is displaying something like plus or minus 100mV

arkantos91 Guys I've noticed that even if I've set my ram voltage to 1.35V the BIOS reads 1.368... which is more than recommended for my ram. Kingston Hyperx Predator B-die 4000 MHz.

Am I ok or should I do something about it? I thought setting it to 1.35 means they won't go over that value...

Hequaqua F42b is pretty decent imo.

I just play some COD:MW(2019) Beta....some cores hit the 4.4.....

My timings are 16-16-16-34 1T and at stock voltage
The kit is - F4-3200C14D-16GTZ Currently 3400 C14.

leoxtxt 3900X:

F42A (AGESA 1.0.0.3 AB):



F42B (AGESA 1.0.0.3 ABBA):



It looks like a small improvement over the previous BIOS (F42A), at least i can see now some cores boosting to 4.5Ghz.

sob0 Soo, is there anyway to keep settings on Ryzen Master after boot?
Cause I think it's my only way to modify those values
