One thing I have noticed on a new install of Boinc Manager when you switch to a local profile the default is 100% CPU cores but 60% CPU time.
This produces a distinct (and AFAIK) "normal" sawtooth CPU load reporting on my task manager.
My real question is the 100%/60% a better load balance than the 87.5%/100% I normally use?
I can speculate that it would reduce screen lag on a heavily loaded system. But would it slow processing speeds more than the 87.5%/100% I normally use?

Please be aware (for privacy reasons) that you can't show your preferences using a link like that. If you could, it would give the world access to your account :-).
(You have to be inside your account to see your preferences and you don't really want others in your account.)
If anyone, including Tom and you (and me) clicks that, they will just see their own preferences, not yours, so that's perfectly safe but not what you wanted. You could copy and paste what you see on your page but you don't need to.
The info you gave after the link is fine - 100% of time, 92% of the processors.
If you are content with the first generation memory speeds, you can bump up to 16 cores with the 7351 cpu running around $600. Or to 24 cores with the 7401 around $600-800
If you want faster memory, then you need to jump to Rome cpus like the 16 core 7282 running around $1300-1400 and can run the memory at 3200.
Supply of used EPYC Rome (7002-series) chips on eBay have dried up. Supply and Demand, prices have gone up across the board. Prices really aren’t great for anything right now. You’ll just have to wait it out in my opinion. I would just keep an eye on eBay for a 7402P (P= Single socket only, generally cheaper than non-P, 7402)
I would say that in the current market, EPYC Milan (7003-series) 7443P is probably the best bang for the buck at about $1400 for a 24/48t. But it’s not compatible with your specific motherboard. It’s unfortunate that motherboard manufacturers have decided to gatekeep EPYC Milan from their lower cost boards even when there’s no technical reason for it. Asrock and Supermicro are both guilty of this and will only support Milan/7003 on their ROME and H12 series boards respectively. I’m affected by this too, I have several AsRock EPYCD8 boards and a SM H11DSi that I hoped to upgrade to Milan at some point, but now I can’t do that without upgrading to a more expensive board :(.
one thing to look out for with these used EPYC CPUs. Be aware of the situation with Dell specific EPYC CPUs. They are cheaper on the used market and you might be tempted to buy one. DO NOT BUY IF YOU DONT HAVE A DELL. What Dell is doing with their EPYC platforms, whenever an EPYC CPU is installed, it blows some kind of one-time fuse, and from that point on, it can no longer be used in any other system besides Dell. It becomes vendor locked.

Tom,
Here is my E@H work preferences:
https://einsteinathome.org/account/prefs
They should be very similar to the discussion we had a while ago about memory usage.
Take note, I use 100% of the CPU time and 92% of the processors. Not the other way around.
I have absolutely no screen lag on my 3950X, and my 3950X is BOTH my heavy worker and my daily driver.

Best Bang for the buck Amd

Best Bang for the buck Amd EPYC cpu?
The price on the Epyc 7402 (24c/48t) has jumped significantly. I don't think it is the "sweet spot" now.
Given the prevailing prices (eBay etc) what is the best "bang for the buck" right now?
I have a 1st gen 8/c/16t that should drive all my GPUs but I would like to be able to run a "raft" of CPU tasks too :)

The good news is all the eBay vendors seem to be describing the cpu's that are locked as "Dell Locked" so I haven't been tempted.
