So, the folks at Optimus were kind enough to send me, unsolicited, a demo Signature V2 to try out, and for comparison to the Foundation block I purchased a week ago (it's a demo unit, not a new block/plate). It arrived today and whoa... this is one finely machined chunk of metal. I mean, it weighs... seriously. Gives new feel to the term: water block
! I used the copper cold plate vs the Nickel cold plate. Changing plates is quick and easy. No jet plate & insert to putz with (uh hem, EK).
Anyway, I got it mounted with this 10980XE/Omega/64gb rig and viola! Temp spread between cores is well within my normal "inter-mount" spread and is low (< 10C vs 12+C with the foundation mounts). I know Trash really likes blender
but I'm finding that HWBOT x265 4K run with 12x overkill (uses close to 30GB of ram) really hammers the CPU (and ram, and cache). So I did my "comparo" with x265 and have blender results too. Overall the temp spread is significantly smaller with the V2 and the peak temps are slightly lower too (2-ish degrees).
The demo kit came with mounting studs that are a bit different than the Foundation kit and appear to be steel vs aluminium... with springs, which the Foundation does not. Mounting on the Omega x299 was not gonna work with the springs as I could not get all four of the thumb nuts to bite (3 - yes, 4 no) and went with a solid mount (Rigid mount for any of you V-twin guys out there
). Simply tightened down finger tight then backed off 1/8 turn. Easy, and works great!
Rig pics below along with SS of x265 4K comparing the Foundation and V2 running the same exact clocks and voltage: 4.7GHz all core @ 1.185V manual override... and that's another story. Multipliers above 44 just will not work with adaptive on this CPU sample since the VID is well above the actual needed vcore. I had this rig at 1.2V for 4.7 but have found that 1.175V is fine. VCCIN is 1.7V which droops to 1.584V under x265, 1.596V under Blender.
