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

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.

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.

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

Is this intended behaviour? I guess it doesn't like having the 5V pins for the PCI card put into the 64 bit data slots for the PCI-X. Probably should have realised that before trying it but I just assumed all PCI are compatible. Good thing I had another T7500 1100W PSU around.

Can I just cut the 5V pin section off from the PCI card and use it? I don't have any more PSU's so I can't risk another one exploding.

Was the issue with SATA only for the motherboard's SAS controller, the additional SATA ports (SATA-0, SATA-1, and SATA-2) or everything?

Is there an equivalent to SetFSB that will work on Linux for these processors/PLL? I've not been able to find anything myself, so that will mean using SetFSB on windows until a suitable overclock is reached then saving the hex values and applying them on Linux using a less user friendly program with no GUI.

Retrorockit Unclewebb the developer of Throttlestop has posted a few comments about Linux overclocking in this thread.
https://www.techpowerup.com/forums/t...op-pcs.235975/
TS overclocking requires an unlocked CPU, and none of theose except for QX9775 LGA771 support 2xCPU. The LGA 1366 ones don't support RDIMM memory so there's a big fork in the road there also. But there is some 2xCPU interest in the TS OC thread. Maybe if you ask there he can point you in the right direction.
