Oh.. I thought he talking about bonchi CPU.

i boot before at 3800 cl20 with an auto 1.3v on the vsoc. I didnt bother to stress test it because it is too high... and i set that as a mistake due to MSI’s stupid “memory try it”

im running everyday 3600 cl18 .. it is good enough... i rather not have memory related headaches when the ryzen is already giving me headaches as it is.

I check back, for Zen 3 also AMD didn't guarantee or safe bet can achieve 4000mhz 1:1. 3600mhz still the best bet.

Well to be fair, officially 3200mhz has always been the promised speed. Anything higher is OCing.

The problem is their marketing, specifically that Robert Hallock clown. He went and indirectly promised 2000mhz 1:1 IF, eventhough it's almost impossible.

He said:



If he didn't said that last sentence, they wouldn't have gotten as much flack as they have had.

Which AGESA version is he referring to, though?

He never specified. Just vaguely said "upcoming AGESAs". Notice the plural form there, lmao that could be anything from launch Zen 3 BIOS until the last Zen 3 BIOS before moving to Zen 4. So he covered his own ass there.

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.

I feel that tRCDWR is too low at 8, I think it shouldn't go below 14 to be frank. You can also lax that tCWL to 16.

May also want to increase CCD and IOD voltage to 1.0. I think VSOC is ok at 1.025, but IME 1.05 is needed to achieve max stability without causing that once in a blue moon WHEA error.

so an update from my supposed testing

can't get a footage yet due to time constraint, nfs heat test done by my son

only tried NFS Heat night race for 3hours+ for 3 days. no blue screen nor crash found on Ryzen 3600 system

might be testing ghostrunner and cod warzone when I have the time

will try find time to setup camera footage as well

I wanted to built a 5900x system, but couldn't find any in stock at reasonable price for the past 2 months
so I got a 5800x instead few weeks back, currently all the parts are at my friend's place in process of building waterloop

today I got wind of 5900x back in stock and selling without bundle
my question is should I get the 5900x and sell off the 5800x?

originally gave up on 5900x and planned to use 5800x until when AMD releases 5900XT later then swap (if they make it)

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?

Anyone knows when clock tuner ryzen 2.0 will be released?

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

Saw some tweet mention it will be released on Feb 3rd ; likely 4th for us...

Will see whether the under volt will work on my chip

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

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

WTB

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

just tested boot to windows and run some benchmark tests

I think most retailer that I've found also sell like this, but their mobo cibai shit mobo

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.
