LGA1366 upgrage to X5670 or 980X

What are you trying to do ?

I'm trying to assemble old hardware into a suitable workstation for rendering by minimal cost.

Just making sure you were not intending to re-use that i7 or try to fit single-socket Xeons into dual-socket motherboard, it's actually pretty common mistake.

What are you trying to do ?

None of those (dual-socket server boards) feature overclocking capability.

You can only overclock 5xxx family on x58 mobo board (single-socket).

Shame that this EVGA SR-2 mobo is not being sold anymore :) ...second hand ones are insanely hard to find as well. It had crazy OC capabilities for dual s.1366 Xeons. 2x 4.5Ghz X5650 mmmmm, sexy!

How much points in cinebench R15?

How much points in cinebench R15?

Dual X5650 @ stock, score around 1300 score in Cinebench R15 - it's quite big, this is the score that new 600$ i7-5930K is getting @ stock!

Clocked at 4Ghz, they should be like 1600-1700! About the performance you get out of new 1000$ i7-5960X with 8/16 cores!

For comparison sake, i7-4770K in my modelling rig scores something around 900 @ stock clocks what one x5650 in a decent X58 motherboard can easily reach with minor OC :)

Conclusion - These old bastards are still very powerful.

Crazy perfomance

Installed my x5650, and overclocked it, now it runs @ 3,95Ghz,

The CPU Cores get too hot I think. Is 81-82*C a normal max temp?

I'd try to keep the temps under 75.

[tomislavn]

Hey! Congrats on your new cpu :)

Hmm not sure about those temperatures, they don't seem very normal for that OC to be honest. Mine work at around 50-55c under load in a dual CPU workstation setup (running stock clocks since I cannot OC though).

You should check if the cooler is sitting okay once again. How did you OC? Auto voltage?

[klyde]

Yes, everything is auto besides BCLK Freq.

Thank you guys for guidelines, I've achieved max core temp 76*C by lowering CPU voltage in manual mode.
