As you noticed, the card does seem to be hitting its full stride now. It took me a little bit (including a new power supply) to get it folding smoothly. And to be perfectly transparent, my 20M+ PPD includes the output of my 2070 Ti as well, so I would say the 4090 is generating around 15-17M PPD depending on the WU. I have seen as high as 26M and as low as 11M estimated PPD in the advanced control, so it is definitely WU dependent.

I did take your advice and am running just the GPU (i.e, no CPU folding) this week to make sure things are stable, and this weekend I may play with tweaking the clocks and power limit. The card has been averaging about 265W (peak 333W) and the temps are consistently around 55C (air cooled, ambient about 20C) so I feel like I can probably increase the power limit and push the core and memory clocks just to see what it is capable of. I am not too worried about power consumption, so it will be interesting to see how far I can go and remain stable for folding.

Thanks for your thoughts on the checkpointing, it does appear that the WUs have hardcoded intervals set that I cannot override so I will just live with checkpointing once a minute... I guess I don't have to worry about losing much work should something go wrong.

Really 15-17Mppd seems like a nice average and not some perfect storm ideal max number calculated off 2 frames such as I see people report.. This a really impressively powerful card and am surprised at the low temps on just aircooling. I would want to try a small overclock on this if I was you, but don't worry about the memory clocks for folding it has little impact beyond reducing stability. I would power limit to a reasonable max temp and then OC up to 18 on afterburner as a test.

We have another folder I don't know under the name of begemotb who may also have a RTX 4000 series card by their output whose current average is 16 Mppd but without the large number of WUs that would suggest this from numerous different systems.

Hi again Kiore,

Based on your suggestion to try a "small overclock" I managed to lose an entire weekend experimenting! Unfortunately, I have also found that there are certain WUs that cause my computer to crash and reboot whether the RTX 4090 is running stock settings or overclocked. I have never experienced anything like it, the system is literally working one second and then a click, a black screen and the system reboots... no beeps, no warning, no error messages anywhere, just a hard reset. This has been extremely frustrating since it occasionally did this before I started experimenting with overclocking so I replaced the power supply thinking it was a power issue, but that didn't help. Then I thought I was doing something wrong with the overclocking but it appears that is not the case, something with F@H and certain WUs cause my system to literally have a stroke.

I did get a lot of benchmarking done and it was fun despite being time consuming. The best 100% stable overclock I came up with was 2,880GHz on the core and +1,400MHz offset on the memory clock. I could actually push the core up to just over 3GHz if I dropped the memory OC a bit and all of the 3DMark benchmarks would run fine, but the stress testing would indicate it wasn't 100% stable at over 3GHz. And even when drawing almost 600W when pushed hard, the card never got above 75C, the cooling is hugely more effective than my 2070 Ti that ran 70C anytime I folded even with no overclock. The 4090 was also amazingly stable and only crashed if I increased the voltage and pushed it hard, so I left that stock at 1.05V. I did experiment a lot with increasing the Power Limit all the way up to 133% of base TDP, and while I did get to over 590W stress testing I am not interested in using that much power.

So thank you for the suggestion of trying for a "small overclock"... it was a lot of fun and I feel like I am getting a little extra out of my card. I am running the core clock at 2880MHz and the memory at +1200MHz and it purrs along at 60C while consuming just under 300W. In fact, it just blew through a WU in 43 minutes with an EPPD of over 25M. Now if I can just avoid the WUs that cause a reboot!

Sorry re "small overclock" advice..
So I am not in the position to jump into the 4000 series hybrid that I would have liked, after being on the waitlist for the 3000 series for nearly two years until it scrapped, I have finally got a RTX 3000 card, a second hand RTX 3070 for a bargain price.
Seems the crazy market were 4 year old cards were selling for more than their launch price is ending finally.
Nice enough card replacing the old GTX 1080 hybrid that was in a teenagers 'homework' gaming rig. Not spectatucular output but runs cool and apparantly the ray tracing helps with homework...
So far it seems to run just a little less ppd (3-4.5 Mppd depending on project) than my RTX 2080ti, was hoping to get a 3070ti but the price difference made all I saw not bargains.

So my RTX 3070 working well and much more productive than the GTX 1080 + GTX 1660ti comination now retired that used to be in this system. PPD ranging from 3M-5Mppd depending on the work unit and much simpler than running two cards in the case.
