I'm in, after all, that's why I mine on my cards (excluding PrimeGrid races that can use GPUs) all year, to pay for my upgrade(s) for F@H in Dec.
I have:
(main rig)
Ryzen R5 3600
RX 5700 (reference blower model by XFX)
GTX 1660ti 'Gaming X'
(secondary rig 1)
Ryzen R5 3600
RX 5600XT (refurb)
GTX 1650 D5
(secondary rig 2)
Ryzen R5 1600
RX 5600XT (refurb)
GTX 1650 D5
(temp test rig)
Athlon 3000G @ 3.90Ghz (OCed) DDR4-3200
EVGA GTX 1660ti triple-slot
(mining server)
2x MSI GTX 1660ti 'Ventus OC'
3x Gigabyte GTX 1660ti 'ITX single-fan'
Note that I've previously tested the mining server, and the ENTIRE mining server, due to the slow dual-core Celeron CPU and the use of 1x PCI-E mining risers, basically limits the PPD of all five GTX 1660ti cards, to around the output of the SINGLE GTX 1660ti 'Gaming X' card on my main rig. So the 'mining server' will NOT be participating in the F@H race, sorry. (Plus, I still need some residual income during the month, it makes $3-5 / day.)
The main rig, I have no problem throwing on F@H on both GPUs, although I might continue to mine on the CPU.
The secondary rig 1 and 2, are mostly similar, I could put them on F@H, possibly, but I worry a little bit about the power draw and them shutting down, I've had some minor issues in the past. (I have them "power turned" for ETH, and they take less than stock power.)
The temp test rig, only has a 470 Apevia (Gah, yeah, I know, I know) PSU, with the 8-pin GTX 1660ti, connected to a SATA-to-6-pin, connected to a 6-pin to 8-pin. "Power tuned" to mining ETH, power draw is not too bad, and hasn't even crashed or been flaky at all. Seems OK, in current situation. Unsure what F@H would do to that rig, I would probably at a minimum swap in a better-brand PSU with a factory-spec 8-pin PCI-E cable, before turning that one onto F@H.
Edit: Forgot one rig, I pulled out a "mining shell" with a Raidmax Cobra case, a G4560 Kaby Lake 2C/4T CPU, 16GB DDR4, and a pair of then-brand-new Asus dual RX 5700XT cards. The PSU is a Rosewill, I think possibly Valens, 600W, but it only has 2x 6+2-pin PCI-E on one cable. I've got it jerry-rigged, with a PSU adapter cable from the EPS12V 8-pin CPU cable, which has a pass-through and a brand-off for a 6-pin PCI-E, and I've got another SATA-to-6-pin PCI-E too. (Both RX 5700XT cards take an 8-pin and a 6-pin.)
Was looking, Newegg (Novashop) has an RGB PSU (Raidmax) 735W Bronze, I believe, that has 4x 6+2-pin PCI-E. Was thinking of maybe picking up one of those for that rig, for $59.99 + tax this BF. Currently, if I don't "power tune" those RX 5700XT cards, the rig reboots when I start to mine with it. (Not such a good situation, and not good for F@H on that rig either.)
Would prefer an 80Plus Gold from a major mfg in that rig, maybe I can make enough mining between now and Dec. 1st to order one. ($120?)
Edit: Installed F@H on my "secondary 1" rig, running 12 threads of PrimeGrid on the 3600 CPU, and F@H on both GPUs. PPD was 556K, last time that I checked. I do have my RX 5600XT set to 1350Mhz / 860mV, and probably -20% Power Limit. Kind of disappointing. Then again, Polaris RX 570 was only around 330K, and that was last year, I'm sure that the WUs have gotten a little harder since then.
