Hello,
A client of mine has recently purchased 75 C6100s. Roughly 100 nodes are clocking down to 1.6GHz. They should be running at 2.8GHz as they are Xeon X5660s. Pre-production testing revealed the issue, they can run ThrottleStop 6.0 and un-check BD PROCHOT, this lets the system run at 2.8GHz. However it cannot be run in production. I am wondering if different HW revisions could cause this behavior, I know for a fact that they have 2 different chassis, and a number of different node revisions. I cannot find anything about the BD PROCHOT feature on any Dell servers. I get nothing but forum posts about home PCs.
The systems behave the same with 1400W power supplies installed, and BIOS at optimal defaults. Changing proc settings has no effect.
-Has anybody experienced this issue?
