ill use this thread to collect some new test bioses for the boards, maybe also to explain some less understood options

to disable cores ccd go here and choose ccd xx bit map down core.
each ones stand for an enabled core
best to disable from the back, ie:
110000
instead of 0011000
after selection press downcore apply changes or discard if made mistake

ocpak/octools

FAQ:
7950x not boosting pass 5.5G -> check that CStates is not disabled
Detailed Explanation on CState Boot Limiter

Test BIOSes:

new:
X3D OC Preset for those MB with asynch BCLK Support: (for simple slight perf boost for X3D)

DOCP/EXPO Tweaked: (for simple timings tightening)

strixe-e 1515

strixe-f 1515

strix e a 1515

crosshair hero 1515

crosshair gene 1515

crosshair extreme 1515

for crosshair and strix e-e:

explanation of segment2 Loadline:

customize a heterogenous loadline for a dual segment workload range.

example above shows loadline=L6 when current is in range of 0~40A, and Level4 when current is above 40A.

Adds for x3d

dynamic ccd priority switch with core flex, os / driver agnostic so win10 win11 ok

Algo as follows:
If condition reached and ccd0 specified, then check current mem/cache activity > threshold and hysteresis reached, if fulfilled then switch
If condition reached and ccd1 specified, then check current mem/cache activity <=threshold and hysteresis reached,, if fulfilled then switch
Default hysteresis =4

Can combine multiple algos for ccd priority so combinations are wide

works on non x3d too but of course senseless on it. detailed explanation here.

As with most things of this ilk, latency will improve marginally in synthetics/benchmarks. Nothing to write home about, though.

EXPO I and even EXPO Tweaked now work for me too (didn't work without manual voltages before).
"Power Down Enable" also works now (it didn't before, no matter what I tried)
Same latency as I had on 2506
I could even make a 6200MT 1:1 / 2067 FCLK with tight timings config.
6400MT 1:1 / 2133 FCLK also booted but was a bit unstable and I probably need more voltage. As I'm a low voltage/idle power/temp fan, I'll stick with 6000 and 1.165 VSOC, lol.

High latency bug after memory training (only on 1st boot) is still present in 2702 but that would be the last problem I would cry about. At least the rest seem to work fine.

About the unknown device you all got (me too) - we are on a beta bios so we probably need beta chipset drivers 🙂 just my 2 cents.

What timings are you using for your 6200 1:1 setup? I'd be interested in seeing some 64 DR timings.

hey guys agesa 1203 bios solve unknown device problem
just need install new chipset driver

AMD chipset driver 7.01.08.129

@SAFEDISK where do this one comes from? Support page with AMD is still stuck on 6.10.17.152 while these provided by you are 7.1.8.129.

9800X3D — X870E Hero — Corsair Dominator Titanium 64GB (2x32G 6200MT/s @ 6600) — MBA 7900XTX — 32" 4K PG32UCDP W-OLED — 2x2T 990 Pro NVMe — Corsair RX Link (AIO+Fans) — APNX V1 Case — Asus ROG Loki 1200W PSU

We will update ASUS official website this week 😁

herozero · ‎01-13-2025

Even the driver page on AMD's site hasn't updated yet. You guys are ahead of the eight ball, you got winning lotto numbers for me, please?
