Stress testing a server with 8X E7-2860's

Long story short... got new servers at work with eight E7-2860's... that's 80 cores (hyperthreading disabled).

I'm trying to find a way to stress test them without actually putting a production load on them. Prime95 x64 isn't cutting it. It only wants to run 20 threads at a time and I'm having trouble getting it to use all 80 cores even if I do run multiple instances and set the affinity.

Any other simple stress testing apps that would be able to push all 80 cores to 100% and use a large portion of the 384 GB of memory in the servers?
 
Why do you have to stress test them? Only an overclocker would consider that. 😛
 
Don't really want to install any agents or any BOINC stuff. I'd prefer a standalone executable like Prime95.

I'm stress testing because these are the first of these model servers that we bought, and one arrived damaged. Yes, they should be able to handle a big load (hahaha) but I'd prefer to do a little "burn in" to see how they handle it to see if I need to add another vented floor tile in front of the rack or possibly not put all 4 in the same rack.

Finding out one of these is in a hot spot or something after they're put into production simply isn't an option.
 
You can start four instances of Prime95 using the switch -A0 to -A3 on the executable. Once you have all 4 going with 20 threads, go into Windows task manager and set the affinity for the cores you want each instance to run on.

Edit: Sorry, I read your whole post and see that you've already tried this.
