WHEA 19 at 1966 FCLK and higher

[Vishera]

The Infinity Fabric on Ryzen 5000 has ECC, and every time it corrects an error Windows logs this as WHEA Event 19 - "A corrected hardware error has occurred." 

 

First time playing with Ryzen 5000 and i have no idea how to fix this issue,

Here is a Zen Timings screenshot:

You can mess with the VDDG voltages a bit to see if that helps get it stable, but it's unlikely to help much. Odds are you need to lower the memory speed to 3800MT/s to get it actually stable. Ryzen chips that can do 2000MHz FCLK without WHEA errors are still pretty darn rare (slightly less so on single CCD chips like the 5700X, but still far from common), it's pretty much just reserved for some benchmarking to be able to use it.

I am not sure how to change the VDDG voltages...

I heard that decreasing them increases stability but hurts performance and that increasing them do the opposite.

Should i decrease them?

VDDG, VDDP voltages affect FCLK stability. 

 

They both have to be lower than your SOC voltage though.

They sweet spot very hard. Tweak them up or down about 10-25mV, see if it gets more stable, if not check the other way. 

 

In my experience, I've not gotten them to help in anything but benchmarking, so I wouldn't really bother, but if you want to see if you can get it to do better good luck.

VSOC is 1.2V, the rest are at 1V

Will it help with the error correction performance penalty?

As long as the performance issue is fixed i am fine with it.

I'm going to put the crazy idea out there that you probably don't need to chase after memory performance THAT much. What use case do you have the NEEDS an extra 1-3% performance? Pretty much anything involving memory tweaking cuts into stability a ton. It's not 2003 anymore where you can go from DDR1-333 to DDR1-550 without huge stability hits (RIP Winbond BH5 and Samsung TCCD).

I wouldn't increase VSOC even more then but you can go to 1.1V on VDDG and see if that helps.

I like overclocking so thank you, but no way i am giving up on it.

Some benchmarks it did, but not all. Y cruncher, for instance, no matter what they were my chip (early 2021 5900X, compared to other chips the only thing remotely decent on it is the memory controller) would slow to a crawl when set above 1900MHz FCLK. 3DMark CPU score would scale to 1966MHz FCLK, especially if I kept cranking the 1.8V rail to unsafe levels, but not further. 

 

I wouldn't bother with this outside of competitive benchmarking. It's just not worth the hassle and odds are it won't help at all.

Same here.  
Just know with this, it can be a chance to learn and improve your own FCLK/RAM tweaking skills.
You'll fail far more than you'll succeed in achieving stable settings along the way (Of course) BUT once you get it all figured it, it's a snap vs how it was before.
I can vouch for that and TBH I've got alot to learn yet myself about it.

I can get my DDR cranking at 600+ sometimes since TCCD is capable of way more than DDR450 speeds..... Like I did earlier this year with a Super PI run.
 

The limitation spelled out was most likely with BH5 ran with a Socket A but even those would normally hit at least DDR460 without issue in the right boards.
Now - With a VIA/SiS chipset I can see how that wasn't going to happen. 
I guess I'm glad I always ran NF2 boards, those rarely gave me problems getting there as long as the CPU was capable itself.

Ahh, Me and my luck, VDDG is broken and is stuck at 1V on the AGESA version i am running, it is the only stable BIOS that supports my CPU on GIGABYTE boards.

Newer BIOS versions are beta versions and reportedly have the same issue.

So i will have to wait for AMD to fix this.

I see you are a man of culture

 

what board and what ram ics?

If you can hit 5000+ i think you can mitigate desync fclk performance hit

That just SUX man but I guess how it is too - Always a PITA dealing with stuff like this.

At least i can run FCLK at 1966MHz without performance degradation, in fact i still get a performance increase.

I barely get 3 WHEAs per minute with that one

[Beerzerker]

Yeah - Most of the time at DDR600 I get a BSOD everytime I click the mouse to start a run.... But I get lucky every once in awhile.

Gigabyte B450 Gaming X, Micron Rev .E

I tried 2:1 to see how high the RAM can go on this board and the highest was 4400MHz,

I will need a better motherboard in order to get 5000+.

Tried loosening primaries, trfc, setting vttddr ~700mv, and 1.6v+ (w fan)?

The voltage slider on this board only goes up to 1.5V

Try running really loose cl

Thank you for the help!, I will try that.

My 5600X is the only one of my three Zen 3 parts that is stable at 2000 1:1 I need 1.156v SOC. VDDG IOD is at 1.065v, ccd is .999 and cldo .999. To get to 2100 1:1 I need 1.175 SOC and IOD 1.075.

With all the testing that i have done, I think that 2000 FCLK could be possible without WHEAs on my 5700X,

Once AMD fixes the VDDG bug from the newer AGESA versions i will try it.

Pretend I live under a rock, what bug is this and what does it do?
