Pulled down the Fedora rig last night and yeeted the MSI Ventus 2060. It is now replaced with an MSI Ventus 4070 Super, Zotac Twin Edge 4070 Super, with the EVGA 3080 Ti FTW3 moved to the last slot. Now it all looks like this:
As any experienced PC person might guess, there is a bit of thermal overload happening here
Also, I didn't realize each 4070S needs a pair of PCIe power cables even though theyre rated for 220W (75 from the connector and 150 from a single cable should suffice...) My Kingwin 1000W PSU is one PCIe power cable short, although it has the capacity for more. I've ordered the extra cable and it will be here tomorrow. In the meantime I'm running just the pair of 4070 cards at their minimum voltage (925mV) and 2640MHz. The card nearest the CPU has a hard time staying consistently below 93°C so the clocks on that one wobble around between about 1900 and 2640.
Regardless, the folding performance doubled, from about 11MPPD to now about 23MPPD, despite the 3080Ti being temporarily offline. And all the better, the doubling of folding perf came with a 10% power drop:
The extra PSU cable arrives tomorrow and I'll have the 3080 back in the running. Then the whole rig should generate over 30MPPD reliably...
Edit: I bought both of the 4070 Super cards on Amazon as "used - like new condition" which is why I have two seemingly random models. I wanted dual-slot cards so I could pack three cards onto the three PCIe slots of this x79 board. Getting them used meant I saved about fifteen percent on the purchase price, and both cards arrived in their original boxes, with their original accessories and paperwork, and with no discernable flaws.
