So it has take a few days to perfect. You know..cable management, alignment, SLI profile building, driver selection, and general tweaking. So the build is: 2x 3090 rtx Founders Edition & SLI bridge 2x 8180M (56/112 cores 1.5 TB ram Asus c621 Sage Dual socket motherboard 4x Raid Samsung 860 pro (4TB each, 16TB total) data and backups 1x Samsung 860 pro (4TB) data and backups 1x Sabrent 8TB nvme for Apps and Games 1x Sabrent 4TB nvme (OS) 1600W digital power supply asus PA32UCX-P monitor Thermaltake P1 micro ATX case (modified..heavily) MS Windows Data Center 2020 for OS 1x pound of flesh and blood Used for research ...and a little gaming I already had a lot of custom profiles for my quad SLI rig, so a few edits and I've been able to get SLI to work quite well. I've moved my 1x 32GB Titan CEO ed and the othre 3x Titans to my wife's pc. Which is also a case mod clone of this machine, because it was my prior build. So far, ...now that its all buttoned up, it seems quite a decent PC, It very quiet, almost inaudible at idle, and creepily quite quiet under load..I like that. Provides no audible presence in room. Temps are nice and cool, under load the cards have yet to get above 67C. CPU run at about 41C under load, and RAM hovers at 55C under load. NVME drives run 28C idle and 52C at the end of a full drive copy. I'm trying to post images but this forum is problematic, hence some are sideways.
