Tom, what kind of PPD are you getting with RX560? I believe Einstein takes advantage of higher memory bandwidth, so increasing memory throughput has some impact on PPD improvement, iirc.
The MB has a specific limit to how fast you can get the ram to run. I forget if there is OC available.
On advice from another Seti Orphan I have switched back over to both Pulsar#1 search and GW Search but right now it is running pure Pulsar.

Please keep in mind the TDP rating is not necessarily equivalent to the actual power a GPU will draw. Also, graphcis cards are primarily for, well, displaying graphics. Some of the hardware may not get used when they are used for GPGPU purposes and therefore don't consume as much power as in a graphics output scenario.
It's not about unused hardware. It's about app optimization. Einstein doesn't use full TDP on nvidia cards because the apps aren't as optimized as they can be. But crunch a project with optimized apps (GPUGRID, SETI w/CUDA special app) and you'll see it pegged up to whatever the power limit is set to.
An XFX RX 570 4GB, using the factory set mining bios, limited to a p-state mask of 0,6, when running 3x FGRBPG1 tasks (gpu_usage = 0.33) on a Linux system, pulls 102W from the wall and generates 500,000 RAC. On eBay, pre-owned are currently selling for less than $USD 100.
Ideas are not fixed, nor should they be; we live in model-dependent reality.

Thank you. I believe that addresses the question of "most effecient"!
I found a cheap source of Rx 550 and have ordered 3 more. So I guess I will have to clump along with 9 of them.

Asus RX560 here tied to an R5 3060. Wall power is around 105-115W, which is OK but a bit higher than I'd like. The RX560 is underclocked to draw about 29W. One advantage of this card, apart from its extreme cheapness, is that it runs on PCIe power. I did need an Arctic cooling solution to keep it quiet. That raised the cost to just cheap.
Interestingly, there was a big increase in daily numbers after upgrading to Ryzen 2. I see that the grav wave search is CPU intensive.
I shut down other experiments (Milkyway) to get an informal benchmark. Daily number - not average - is heading towards 100K and still rising.

Thank you for the note on the CPU intensiveness of GW gpu tasks.

I have forgotten what a "PPD" is. However, I have a mixed Amd gpu/Nvidia gpu system running here: https://einsteinathome.org/host/12828668

PPD is Folding@home lingo. most BOIC users say credit per day, or or more generally might refer to RAC.
