Wow dude im sorry to hear that your psu went out. Hopefully you can sort it out buddy? LMK how your overclocking goes

I wonder if that's what's going on with other computers that lock up at low FSB increases? My G41 Optiplex 380 X5470 only goes from 333 to 340fsb. I may have to try this. i wanted to OC the 65W Q9550s. But went with the Xeon swap when it crapped out @ 2,880Mhz.
I picked up a MB for the X5687. An Alienware Aurora R1 Micro ATX with unlocked BIOS.
There's a Dell Workstation owners club at TPU.

Memory

Those of you who successfully overclocked your dual xeon machines. Are you running a higher speed DDR3?

I have (2) X5680's and 24Gb of DDR3-1333 ECC. And the second I start bumping up the FSB my multiplier starts jumping around and any measurable performance gain is lost. Wonder if I should go DDR3-1600 or higher? At that point I think you loose ECC and so I'm curious if there are much if any benefits to be had here?

Specs:
T5500 (same PLL)
(2) X5680
24Gb DDR3-1333 ECC (3x4gb) (3x4gb)
GTX 1060-6GB
Windows 10 Pro
Marvell Hyperduo running 4 EVO860s in RAID 10.

Here is a Notebook Overclocking thread with all kinds of methods to unlock settings. They were rewriting their RAM timings on the modules themselves.
