Xeon x5650 on Dell T3500 overclocking

Hey guys, I tried to overclock my Xeon via SetFSB and WR-Everything. I know the Pll and which byte I have to change and it works, but only if I increase the value very slightly. (about 5 points) When I change it harder, the PC is going to freeze.
Can anyone tell me what am I doing wrong? I know serverboards are not made for overclocking, but I want to get that running. Im happy about every answer.

    With some modding you can do a very slight oc with the t3500 but the chance of killing your board is extremely high for a 5% non guaranteed working oc.

  3. The W3690/3680 is what you want. I PM'd you some tips on overclocking Dells. I'll let the link in my sig. show what I mean.

  4. Here are some T3500 builds. no OC as far as I know. You will notice no recent Radeon GPUs. they won't display the Dell BIOS screen.

  5. Are you set a six core CPU? If not I would suggest a 4-core X5687, which can usually be had for $40-$50. Works great in these T3500. As do the RX 480.

    Hey Jaslion,

    thanks for your answer! What type of modding youre talking about?

    Hey Susquehannock,

    thanks for your answer too. I have a six core CPU, and I was impressed of the overclocking results with this processor (with about 4ghz and more!).

    Maybe I will buy a W3690, as William said...
