V7.10 broke my links to startup multiple clients with GPUs and I've never gotten around to updating BOINC versions. The thing throttles like a mofo so I should really start there. It just runs [email protected] for a few tasks until the 10min window passes and it downloads 300 more tasks.

I'm under water so no throttling, but I've been testing the VII at 1745core-1000mem-1v and power capped at 200W. At those settings, running 6 concurrent tasks, I am averaging about 60ish seconds per task, or 6 tasks per minute depending on how you want to look at it. If I ran it 24/7 that would be approaching 2M ppd on the VII. Not bad for a gpu that can be had new for $550.

absolutely The VII is the card for DP work. I have not been able to get 2M ppd out of mine yet, but close at 1.8M.

I now have three VII's in my workstation. I haven't been running MilkyWay 24/7 on them, but they are going to get a workout over the next few days.

I have been dialing in the clocks, and doing a fair bit of testing, but now they are ready to go. The only issue I have is one of the cards is running about 10°C hotter than the other two. I thought there was something going on with the bridge (EK triple parallel bridge), but after mounting and un-mounting the block 3 times, it appears to just be a contact issue on the one hot GPU. Increased mounting pressure did help, but the GPU/HBM package is slightly convex, so I'm worried that I'll crack the die if I go any higher on the mounting pressure. Temps are still pretty good at 55°C edge and 80-90°C junction.
I pulled my 7970's and 7990, but I may get them added to a spare motherboard I have, for a bit more winter time heating in my office.

I run this VII using the AMD automatic "Undervolt" which yields a 1770-ish clock @ 1.06V core, 0.89V SOC and really tames the hotspot.
Yeah, a convex contact package can be very frustrating. One of my TXps has that and never really could get it as cool as its partner. Went thru all sorts of TIM and mounting(s). Pressure-sensitive contact paper showed the problem... that I learned to live with. Without a doubt tho, the VII is the best compute card available today for the buck. I had 2 RTX Titans and they were just terrible at MW and most other jobs compared to teh price of the 2080Ti, which has 95% of the capability.
I'm currently running 3 TVs on one rig. They still use the less power for slightly better productivity than the VII (130W vs ~230W each) but still cost too much. Considering how old they are, can't knock the Volta.

I was running the VIIs at 2025core/1175mem/1.2v, but the gains were pretty small in MilkyWay (maybe 5 seconds per task) over running at 1750core/1000mem/1.0v and capped at 200 watts. I might do a bit more testing to see how low I can cap the power before performance really starts to tank.

After all the mounts and re-mounts I'll just live with the hotter card, and keep it under-volted a bit further than it's neighbors. I was very tempted to lap the package, but the last mount resulted in acceptable temps so I just left it.

The Titan V is an awesome GPU. I only got to play with one for a few weeks around release, and the performance was truly great even with the high cost. I am always looking to pick one up, but the price hasn't really changed even though it is 3+ years old. With no actual work for the V to do, I haven't been able to justify the cost... yet.
