AMD Fine Wine, CPU edition, now waiting for ASRock to release one for me too 🙂

Anyone tried flashing and seen improvements? Thinking about trying it out myself.

yeah... tried the latest x570 taichi bios (v3.40) with "AGESA Combo-AM4 V2 1.0.8.0". My RAM xmp profile was unstable again. had to gradually revert back to v2.70 and now it's stable again. hope asrock will fix this.

Im gonna be trying gigabyte today. Its gonna be interesting to see does it improve latency on zen+.

No real improvement for me and I’ve been running it for a week or 2, maybe 1-2ns or so but well within error of margin.

I updated the Bios on my gigabyte 570x Aorus Elite mobo, but to be honest i dont see any improvements with my 3700x CPU. Still dose not reach the 4.4Ghz without PBO. The maximum boost is 4.35Ghz or for a fraction of a second 4.37Ghz.

Hey Alex, welcome to Guru3d. And yeah, I'm on the same boat. 3700x with an x570 board, water cooled. I don't go anywhere near the 4.4 ceiling. The best I can do is a 4.3 boost with PBO turned on, but obviously it cannot be sustained. I think all core is 4.17 under sustained benchmark load.
At this point, I think the biggest wins on our platform that we can manually tune is RAM overclock.

Can i update my B550 (Gigabyte Elite) ? Any benchmarks?.
magiQx
Hi, got the same CPU on an x570 (taichi) and water cooled as well. sometimes while gaming i see the frequency reaching 4.4GHz but only for some seconds and not continuously. Did not yet try to benchmark all cores to see the max frequency.
unfortunately i had no luck with manually tuning my RAM and had to rely on XMP. Manually i could never reach the default ram specs (15-15-15-15 @3600MHz).
AlexM
Thank you for the warm welcome! 😀 Well, i have a G.skill 2x8Gb 3200mhz cl14 kit and i use XMP, it's enough for me 😀

A member of our forum created a RAM Calculator that is extremely useful for tightening your performance of your RAM on an x570 chipset. I've yet to use it myself, I'm overall happy with my RAM on the XMP profile, but you do get an increase on your performance with the application's help. There are loads of YouTube videos out there that show how useful it is, particularly when RAM performance impacts your Infinity Fabric performance.
May be worth a gander if you're looking to squeeze more performance at no cost besides time spent.

Getting XMP instability with 1.0.8.1 on MSI x570 Unify. HWiNFO64 reports WHEA error. Event viewer shows correctable Bus/Interconnect Error, Event ID 19.
I saw an identical report for an ASUS mobo the other day, so it's not limited to a specific manufacturer - which points to AGESA being the issue.

I used the new AGESA update on my B550i Aorus Pro AX (itx) motherboard.
I have AMD Pro 4750G APU. Memory is G.Skill FlareX 2x 3200CL14 running with XMP1 profile.
TSME enabled and before update the latency test in AIDA64 showed 80ns.
TSME enabled and with new AGESA, the latency showed 65ns. Thats an significant difference. Scores in Cinebench improved around 40 points and gained 3fps in OpenCL test from 87-90fps (Cinebench R15).
Turning TSME off improved the ns further to 60ns. TSME is ON only with Pro cpus.

thats cache stage, not memory.

MSI claimed this AGESA improved memory OC headroom, and given reports of lowered inter-core latency, we're looking at Infinity Fabric changes.

Had the same problem on my X570 Phantom Gaming 4. I was so bad that it was barely stable on the desktop.
magiQx
exactly. first it started with artefacts on the screen, then with glitched sound and after that continuously reboots until the bios reverted to default.
geogan
FFS. I was reading this and wanted to know which version of AGESA BIOS I actually have now on my ASUS Hero VIII x570 - haven't upgraded for a long time. So I tried to run the "ASUS Update" app and it fucking well blue-screened the PC completely. Buggy POS.

with the EDC bug in place, my 3700X in PBO mode, can go up to 4425 single core (+25 from the max 4400) and boost all the cores to 4325 (sometimes 4350) which is the stable value I can manually setup but with a lot of heat, here no heat.
if the new bios improve this even more... wow...

I think you're also on overclockers.net.
I solved it somehow by raising VDDG to 1.050v I used to run it at 0.950v long time ago without issues but every bios update changes stuff. ran it on 1.0v for a while without issues on A40 and A50 bios. but now it needs more...
Might be related to this posting saying internal latency dropped. Maybe internally something is more voltage demanding because of that. Who knows...
EDIT: I just checked my MSI webtickets and they had responded with the same suggestion to adjust VDDG. You can try something higher. For me it's 1.050v that does the trick.
