I found a bigger increase in performance going from 2x16gb to 4x8gb than I did from any jump in ram/IF speed.

It was only some quick back to backs in Timespy CPU, as my motivation to change wasn't really performance but I was curious nonetheless.

I've since settled on 3800/1900 CL18 as there were lots of WHEA errors at 4000/2000 and I was getting occasional memtest errors at CL16

Which 2x16GB sticks did you have? Single or dual rank?

Single.

If the 5000 series uses the same IMC which they say it does I think 4000/2000 is going to be unicorn territory.

Not many chips will achieve it.

Probably what they have done with the 5000 series is make it more common for 3800/1900 speeds to be achieved compared to the 3000 series.

I could definitely achieve 3800/1900 with the old AGESA, so I think it's reasonable to hope for more if 1.2 does eventually get released.

BTW nice quote on your sig

Ex navy or a fan of history?

Ha! Nah nothing as sexy as that. It's from John Wick.

Hey, John Wick is a damn masterpiece IMHO.

I managed to get mine running at 3866 all coupled. Timings are 18-22-22-41 which matched the DCOP profile provided with the sticks. Running for 2 days now without issue. Passed Ryzen Master stress test and CPU-Z, R23 and Timespy benches. Performance gain equated to around 200-300 points on those benches. Previously I was running at MCLK 4000, 1800 FCLK which defaulted the UCLK to 1000 Mhz. I'm on the latest 1.2.0 AGESA on my Asus mobo.

MSI just dropped 1.2 for the Tomahawk:

Seems Gigabyte have too, its in Beta tho.

Has anyone else seen a decrease in performance when going to 1.2?

It’s only small, around 1-2% but quite consistent across all benchmarks.

Annoyingly, while it’s made 4000/2000 more stable, I still get some WHEA errors.

Dunno, i don't update the BIOS unless its actually necessary, i'm still on 1.1.0.0, i see no reason to update, not until i get a new GPU.

I needed to update to 1.1.9 to get my RAM stable at XMP settings.

My main reason to try 1.2 was for a combination of Resizable BAR and to see if it would get me to the magic 4000/2000 milestone.

I started on 1.2 so can't compare however aside from CPU-Z, my benches have been a bit below average. Are you getting the expected performance from 4000/2000 all be it with the errors you're getting? My performance tanked at when I set mine to that...

Steedie · 4 Feb 2021 at 15:46

Not seen any performance loss, but I am seeing higher temps on an ASUS Crosshair Hero VIII X570. Not under load but idle temps, my idle would sit around 35 pre-1.2, now I'm pretty much always at 45-50. Under load is still 70, so something weird has changed with voltages at idle

pc-guy · 4 Feb 2021 at 15:49

got 1.2.0.0 on X570 unify as stable release rather than Beta now.

the date was stamped 25th Jan but I am pretty sure it was released within the last 24hr or 48hrs max. cheeky little sods.

philo-sofa · 5 Feb 2021 at 09:28

Okay, guess it’s time for me to put my money where my mouth is and perform another BIOS flash

pc-guy · 7 Feb 2021 at 22:55

Just applied 1.2.0.0. Has not affected my OC or improved it.

I was not able to boot from 3800Mhz on my ram previously, now I can get into windows. But it is not stable. Not sure if it is ram or controller. Able to run Aida bench on the ram but as soon as doing the cache the system reboots.

anyway either bench on loose timing is really the same as 3600Mhz with C14. So nothing much to gain. But good to know it seems to offer better compatibility with ram.

Cyber-Mav · 7 Feb 2021 at 23:55

Damn will 1.2 allow me old ryzen 1700 to do 3200 with 4 sticks?

That is what I'm on too, and I'm incredibly reluctant to change a system that is working perfectly for me already. I suspect I'll stick with what I have for a while.
