I'd like to know what motherboard and BIOS revision being run there. I'm on a T5810 with a K240Y board with A33 BIOS, same processor, but Throttlestop says "Turbo Overclocking - Locked" and I can't change anything.I'd like to report a successful overclock of a Dell T5810 workstation using an unlocked Xeon E5-1650z3 to 4.5GHz.
The Xeon is known to be unlocked, but we weren't sure if the workstation chipset would allow overclocking in these systems.
Intel XTU, and Throttlestop software can do this on the locked BIOS system. Throttlestop is preferred by this user. His posts start at #1018 on this page.
WARNING Dell went to a proprietary plug and play PSU format on their workstations newer than T3500. Do your research on this if you want run a bigger PSU in one of these.Throttlestop overclocking Desktop PCs
Now a 4GHz QX6800 without SSE4 has some real limitations!www.techpowerup.com
Edit to add: Looks like I had to do a sleep/wake cycle to get the system unlocked. Default max multiplier is 38, seems I can only push to 40 without bluescreening.... so 3.990GHz CPU.
