Latest C7H BIOS

[EZ_PC_TECH]

2801 has the SAME SMU Firmware as The Stilt's 0002E. ver 46.49.00

It does not appear to be propagating on regional asus sites yet, so may not be official yet. Boost seems ok but I have had a few things happen which didn't happen on 0002E, but not enough testing done yet to be sure of anything.

Can you tell what exactly new you have noticed? And if you don't mind, can you provide a link for 2801?
Thank you in advance!

2801 seems to be running well for my C7H+3700x compare to the previous 2703 BIOS
here is my result from cinebench r15
all stock except ram oc, Flare-X 3200Mhz CL14 * 4
going to leave it as is for daily use for now till I find sometime to play with the oc

The BIOS with new AGESA 1003 ABBA that must improve boost for Ryzen 3000 available for download through the BIOS EZ-Flash utility for C7H. Not published on the website yet. Share your results!

Geekbench 4 comparison between 2801 and 0002M-FIE, same bios settings



It do reach 4.6GHz briefly, my current max boost for all 12 cores is

4550
4600
4600
4450
4425
4525
4325
4325
4300
4375
4300
4375

Cinebench R15/20 is roughly on par with 0002M-FIE, but R20 is about 100p lower in multi than 0002+(or 2501). But could as well be because of ambient temps. Memory bandwith is the same.
Bioses 2501 and 0002+ still has the best benchmark scores and the highest boost, but this bios probably has less bugs.

Still annoying with the latest bioses is power consumption is hard locked at 144W/95A for 3900X when using Auto OC/PBO, PPT/TDC/EDC settings makes no difference, which limits benchmark scores. Only way to overcome this is manual OC as far as I can see.

But why do 2501 boost better? Probably mostly because it has higher temperature tresholds.

Still kinda nice with a high performing 12-core that can't consume more than 144W no matter what, when Intel is releasing 9900KS an 8-core which will happily consume over 200W at stock(the 127W TDP is base frequency only, noone will lock it at 4.0GHz).

With the new bios "ABBA" for the CH7, the problem of fans stop is solved?

[bigtop1967]

Not sure about the fans problem.

I had some problems earlier when I changed a couple of timings - nothing that should have caused a problem.

What happened was that I'd get mem training fail with code F9 3 times, then instead of getting Safe Mode it was just loading up defaults and resetting, which took 3 loops (very slow). Advanced Tweaker settings were still there but anything on Advance tab was gone, even if you set it not to delete them.

It looks like these problems are fixed by loading defaults and rebooting before reloading OC profile. Perf seem slightly down for me, but more testing is needed.

Ran CB20 right before updating and right after updating I lost 79 points. I’m running the same bios settings with memory overclocked to 3600mhz. Lost about 19 points on single core as well. Currently running karhu ram test to test ram stability.

Edit: Ram is still stable for me.

Finally.

Also anyone using this Bios should Disable DRAM ECC mode in the bios unless the feature is supported in the spec sheet of your ram and you intend to use it.

Best single in CB20 for Auto/PBO so far, multi is 80p lower. Temps are 1-2C lower.

I did a Clear Cmos on the old bios and then installed using Bios Flashback, my old profile worked right away and booted at once. 3800MHz mem 1:1:1



R15 is ok too
