I have a G12 coming this week to try on my S9100 with an Arctic Liquid Freezer 120 that I had on my 2600k CPU before I upgraded to a 3900X and new cooler. Curious as to how it's going to work. Wish I knew if 7950 or 280X coolers fit this card.

I'll have to try that 20q1 Pro driver as well as you seem to have it working well. Getting full speeds with it as well I hope.

non turbo coolers from "parts only" 7950 work fine with S9000 but NOT the 9100 which has a different chip: Hawaii.

The s9100 has a larger rectangular chip, not a diamond shaped chip (the layout on the board). I suspect you will need a copper shim. I do not want to take mine apart but I remember trying to use an Nzxt with a cpu cooler and had to get a copper shim as the chip was recessed. Not positive, maybe it was the s9000 that needed the shim. PM me your address and I can mail you two different shims if location is USA.

I recommend the following, a Dell part that I got from North America for S9050

you can google for BG0903-B047-VTL and I think Newegg also carries it. The shroud fits the fins of the cooler perfectly and is easily held on with aluminum tape. Only works on an open air mining rig due to the length. Try to get one that is not from china as not economically returnable if defective. One of two I bought from Newegg was DOA, obviously used. Both were 3rd party from china.

Thanks, I should be good on the shim material as I have copper here at work. You know the thicknesses possibly needed? Also, what did you do for the memory chips and VRM? I'd rather not have to cement small heatsinks to them.

Finally got my S9100 with a cooling solution to be able to run and installed in a Windows 10 system :)

Reading through this thread...did you guys ever figure out the "Invalids" issue? Is it the driver/GPUs or is it BOINC/MilkyWay that is the issue?

I'm on Radeon Pro 19.Q2 package with ECC enabled running 5 WUs. I've had issues the passed day trying to get the right drivers and the system/BOINC recognizing the S9100 so I'll need to wait a few days for my "Validation inconclusive" tasks to clear the old ones out and see how it's going.

I'm also using Sapphire Trix v5.2.1 and it sees the S9100 and I can change the Power Limit to 20% to get it at 824MHz. Can also change the GPU and Mem clocks, but haven't yet. Voltage setting is a no go and locked at 1.106 VDDC according to GPU-Z. Settles in at 73-75C for temps with VRMs at 59C and 70C according to HWiNFO64.

Well these Invalids everyone was having is not a driver or GPU issue. It's a BOINC and/or MilkyWay app issue. If I run 5 concurrent WUs on my S9100 then I get Invalids. But if I fire up five instances of BOINC each only running 1 WU per instance for 5 total WUs on the S9100, then I get no Invalids.
