Titan V on order... pics to come

Awesome!

Woah..now that's a workstation..can't wait to see pics!

These builds here make my 7900x Workstation look amateur..gonna have to step up my game I think.

Having said that, it's all about use case.....

Sorry for the delay in updates...this project has expanded to 3 separate 6154 builds.

I do have 2 questions for the forum:

I’m using the Supermicro 4u active heatsinks as I can’t find anything better, resulting in mid 80’s temps when under full load. This seems high but the Intel stability tool says max of 104. How hot is too hot for SP? I found that coolit has an AIO liquid cooler but since they don’t sell retail the minimum order is 1000 units. Noctua showed a prototype heat sink but claims no plans to produce.

Other question relates to 2 vs 3 UPI. Many Supermicro boards only have 2. Big performance difference?

Isn't more than one UPI link only useful when you have more than two (more precisely: four) CPUs on a shared memory system? So that each CPU has a direct communication path to every other CPU on the board? Is it even possible to bundle these UPI links to get a higher bandwidth between two CPUs only?

Exactly, in a 4 cpu config you get a cross bridge type setup rather than just a ring. In a 2 cpu setup I can’t iamgine it helps having the 3rd but maybe I read it wrong (and I have not touched a greater than2 cpu intel box for years... always scale out and not up after dual socket or got to IBM for power systems

I don’t know but then why would they bother making 2 socket boards with 3 UPI? About half of them do.

oh boy.

Maybe 3 UPI is used on the ‘M’ versions with the extra memory or maybe all the 3 UPI cpu’s can use extra bandwidth but I hadn’t seen it described (google’ing just now I didn’t see anything other than the relevance to 4 cpu config)
Must be referenced somewhere why it is so...

Ok so turns out (according to Intel) that max temp on the 6154 is actually 102 C which seems nuts. They are telling me that mid-high 80s under load is no big deal.

Did you end up building this workstation? Did that power supply power up that board for you?
