Info PrimeGrid Challenges 2025

Errors from the client would not make the score go down as the server would never see them as possible valid work. The 35k would need to be something completed as OK (Potential points during the competition) by the client but checked as No Good (Score reduced) by the server or comparing between main/check tasks. An Invalid so those CPU tasks.

That's what I said.

That pic doesn't show the whole picture.

That box has:
14 CPU errors
19 GPU errors
20 CPU invalids

This leads me to believe it's most likely RAM related or possibly the SSD/disk is going bad. The latter part I'm guessing because some of the errors are related to this error
"Error: gproof_102.ckpt: bad file (crc32)"

Could this be the result of a drive failing and not writing the data correctly? It's a stretch.

Which is why with both CPU and GPU tasks being effected I'm leaning towards something wrong with the system memory causing errors.

However, I do agree with Tony that even an under volt or power limit can cause errors just as much as an overclock.

Bottom line is. Something is up with that system and it's effecting more than one thing.

edit
Upon further investigation it seems the only valid CPU tasks were returned late on the 16th and on the 17th. No CPU tasks before that were valid results. This leads me back to a possible heat problem. If the temps got lower on those days, but was higher on the days before. Then that could be the problem.

Edit2
Also seems the CPU tasks that got marked invalid took more time than those CPU tasks that did validate. Which could have been the result of heavy CPU throttling. Again pointing towards heat.

I'm on my phone trying to look this up. Someone, like Mark, should put all that data in a spreadsheet to sort through the data better by separating the errors, invalids and valids for CPU then do it again for the GPU in that box.

Well, the first thing is to check BIOS for that and the 9950x (also a problem, 7 of 40) The 9950x temp was at 95c (stock) and I set it to 80c. The SOC in bios was red at 1.35 and I set it down to 1.2. Now on the 7950x3d, it had already rebooted, so I know there is issue there. I wanted to check SOC and max temp in bios, but its the damn ASUS ROG bios and I can't find those 2 to change. There are screens that have SOC in the name, but is it memory or CPU ? and what name might they go by. Somebody that knows the ASUS ROG bios could be of a lot of help here. !

OK, thought I found it and it was 1.39, changed it to 1.2 and it would not boot, so I set it to 1.3 on the 7950x3d

That's what I said.

Your 2nd edit to the post immediately prior mentions errors which have no influence to the issue at hand. Going thru any error would be a complete waste of time.

What are you talking about dude? This post? https://forums.anandtech.com/threads/primegrid-challenges-2025.2624853/page-8#post-41464461

Speaking generally without having looked at the results tables, there can be calculation errors which either the application or the client detect themselves, and calculation errors which only the validator ( = server with help of another host) detects. The latter type of errors is the one which cause point deductions in PrimeGrid challenges. Yet *if* there is interest in improving the host to compute correctly, it is obviously worthwhile to look at *all* of the types of errors to get a better picture of what went on. :-)

I know this is about the August PG race, but before I forget, I will be out of down for it.

Big Disney trip? Hope you have a blast!

The upcoming AP27 challenge should be fun, in my experience CPU is terrible.

@TennesseeTony and @cellarnoise, that's a beautiful display of Synchronized AP27 Search. :-)
