Xeon X5650 OC Help

Hello everybody, i have a question regarding x5650 overclocking..

I searched everywhere (forums,youtube..) for x5650 OC options,but none of them work.. I either cant boot (need to get the CMOS Battery out and put it back in) or i just keep restarting.

Can anybody of you people help me with OCing my Xeon?

These are my specs:

MOBO: ASUS P6T6 WS Revolution

CPU: Intel Xeon X5650

RAM: 10GB DDR3 1333Mhz (dont ask,its 4+2+2+2)

GPU: Gigabyte G1 Gaming GTX 1070 Ti

PSU: 600W Chieftec

I have a LC-CC-120 Heatsink with 2 120mm coolers mounted on it.

(Please do not comment anything like "GET BETTER TRIPLE CHANNEL RAM",i know.)

Are you making sure to drop the memory multiplier when OC'ing? BCLK OC's will bring up the memory speed.

Main: AMD Ryzen 7 5800X3D, Nvidia GTX 1080 Ti, 16 GB 4400 MHz DDR4 Fedora 38 x86_64

Secondary: AMD Ryzen 5 5600G, 16 GB 2667 MHz DDR4, Fedora 38 x86_64

Server: AMD Athlon PRO 3125GE, 32 GB 2667 MHz DDR4 ECC, TrueNAS Core 13.0-U5.1

Yes, I tried 1 option but wasnt exactly sure which one. I wanna hit 3.6-3.8,i forgot to mention that.

Looks like you'll need a 164 MHz BCLK to hit 3.6 GHz.

Set a 22x multiplier, disable c-states and turbo boost.

Memory should be set to the 1066 MHz multiplier, which should give ~ 1300 MHz.

Most Westmere-EP Xeons should be able to do this without voltage bumps.

UPDATE: I finally got my hands on my PC,and i tried the settings above...

I kept BSODing,the only stable OC is 3.4ghz without voltage bumps
