2000 are for golden samples only as far as I can tell.

Based on what I read from other forums, Ryzen 3000 max realistic RAM target is 3733, whereas 5000 is 3800. Not sure if my CPU's SOC is a lemon or if it's a mobo BIOS issue, since I can get IF clock to 1900 or RAM to 3800 stable without issue individually, whereas it's extremely unstable when booting at 3800 in coupled mode.

Which AGESA version is he referring to, though?

Final stable speeds on my Crucial Ballistix 3200C16 dual rank kit. VDIMM is 1.36V. No other timing adjustments seem to scale with RAM and SOC/VDDP/VDDG voltage at this point to be worth it (tried everything at 1.4V VDIMM, 1.1V VSOC, 1.05V VDDG, 0.9 VDDP).

tRAS was stable as low as 23, although 1usmus guides on the Internet tell me I should use tCL+tRCDRD, AIDA benchmarks for both tRAS 23/30/35 seem to be within margin of error. tRCDWR seems unusually low but even at 8 it passed TM5 anta777 config + 300% HCI.

Since 5000 series CPUs are supposed to hit 3800 RAM 1:1 with FCLK, gonna take one last crack at it.

If anyone has any ideas how to improve timings even further or run without geardown mode without dropping 1T, I'm all ears.

Is there any correlation between core CPPC values and Clock Optimizer max stable negative offsets, other than the highest valued cores being favoured for 1T operations?

Also, what is the most reliable way of testing core instability? Cinebench seems to knock them out faster than Prime95 can, but only seems to be reliable at testing global values in Clock Optimizer as Cinebench keeps resetting manual core affinity in Windows even when running 1T.

Hmm, ZenTimings is reading incorrect values for voltages.
VSOC =1.05V
VDDG = 0.95V
VDDP=0.9V

I did see a crash during 1/3 TM5 runs at 1.04V, whereas 1.05V seems to be solid.

Depends whether the current 5800X is gold or a lemon. Did any overclocking on it previously?

There's a closed beta right now, a handful of sites are currently testing it. I know Igor's Lab has access to it.

I'm already trying out curve optimizer as I speak haha

Would be nice to see what CTR gets for my CPU though!

I might be able to source an extra 5800X without retailer scalping but it'll be with a mobo combo.

Depends, I've seen a small store offering a few with Strix B550-E earlier this month. Only 5800X though. Guess 5600X/5900X sells out way faster due to better price per core ratio.

There is some correlation between CPPC values and voltage, but it's not consistent.

CPPC values, core priority from HWInfo and Curve Optimizer negative offsets below that survived 24hour Prime95 blend test:
127 7/8 13
146 2/3 10
143 3/4 16
150 1/1 10
135 5/6 13
139 4/5 16
150 1/2 8
131 6/7 15

Started with -20 and slowly bumped up the offset for any crashing cores in Prime95.

Now to figure out if it's stable during low power usage... what tools would be best to simulate that?

No WHEA errors so far... then again I didn't test this extensively by adjusting other values like LLC or voltage offset yet.

Haven't figured out what's a good tool to use to test that though. In the meantime, gonna give CTR 2.0 a spin - but I probably won't use it for daily until it supports curve optimizer.

CTR tells me my CPU is a "silver sample".

Only advantage to using it is that it emulates a hybrid mode similar to the Asus Dark Hero, so it swaps all-core overclocks for max single core mode when low CPU usage is detected.

Curve Optimizer is planned for 2.1 so I'll wait for that. This tool as it stands right now seems best to fish out the quality of your CPU. Mine is a "silver sample", wonder how well "golden samples" work with Curve Optimizer.

I have not tested manual clocks in BIOS. Curve Optimizer tuning is more in line with what I want to achieve, since all manual results in lower clockspeeds than the maximum possible single core turbo speed achievable. CTR of course aims to remedy this by switching off the all core overclock when low CPU utilization is detected (similar to Hybrid OC on the Asus Dark Hero, but with different detection methods), but another aim of Curve Optimizer is that it can potentially reduce power consumption even after hitting max turbo clocks. CTR will only support Curve Optimizer in version 2.1.

Mine passed 30 mins of Cinebench R23 on top of the 24 hour prime95 loop. Try reducing your negative offset until it passes.

While Cinebench was faster at generating errors, Prime was so much easier overall to thread schedule, especially when I'm setting curve optimizer at a per-core level.

Asrock can be pretty decent too if you aren't buying Z490.

Strix-E pricing is kinda ruined in Malaysia though.

Z490-E is priced to go against Aorus Ultra in US, but in Malaysia it's just a bit short of Aorus Master pricing.
B550-E is priced to go against B550 Aorus Master in US, but here's it's price closely matches the X570 Aorus Master instead.

As for B550-I, it doesn't look anything special compared to the X570-I variant - I would have bought it without thinking if it just copied the X570-I's feature set and added a USB-C front port header.

Can't see them having any "major" releases this year other than new APUs and Threadripper though.

Zen arch releases are on a 5 quarter schedule so far so I doubt we'd see any this year too. Not to mention Apple has already gobbled up all of TSMC's 5nm allocation this year IIRC.

Isn't Qualcomm also on Samsung 5nm this year?

And their power efficiency is pretty weak vs last years flagships, shows why TSMC is in high demand in spite of supply issues.

Does the Strix X570 ITX also have problems that the B550 one doesn't?

More likely due to binning for 8 cores.

But since there's a shortage everywhere, 5800X ends up being the easiest to go for, since there's barely any 5950X anywhere on this planet, and everyone is chasing for 5900X and 5600X.
