CPU compatibility

[william0]

I'm looking to upgrade my cpu from an i7 920 to a X5675. Though they both have the same socket, I'm worried that my board a gigabyte EX58-UD5 won't be compatible with the X5675 as it isn't listed as a supported cpu: https://www.gigabyte.com/Motherboard/GA-EX58-UD5-rev-10/support#support-cpu

Even though it isn't listed does anyone know if it will still work?

X58 motherboards should support all 1366 xeons

It would come down to that CPU being supported in BIOS. You might be able to get a BIOS modder to add it over at bios-mods.com?

Though the consensus here seems to say "yes, if you make sure you are on the latest BIOS": https://forums.overclockers.co.uk/threads/xeon-x5675-and-ga-x58-ud5.18297386/

Well, I personally am not too experienced with first gen core series, but the difference you are gonna get between a 920 and a X5675 really aren't going to be all that great. I would recommend buying an Optiplex on eBay with a 4th gen i5 or something and swapping your graphics card, PSU, and storage over.

It's lower wattage and more cores... https://ark.intel.com/content/www/us/en/ark/compare.html?productIds=37147,52577

It would make a noticeable difference - especially since the X5675 is crazy cheap (I just got 2 for a dual socket board).

I say go for it - you can always sell the X5675 on in the unlikely event it doesn't work. They're pretty popular atm.

edit: The X5675 is in a sort of sweet spot (for LGA 1366). It's a 3GHz+ base clock, but still 95W. The next one up, the X5680 jumps to 130W for little gain. It also has a higher Tcase of 81C vs only 68C for the i7-920.
Here is a side by side of the i7-920, X5675 and X5680 specs:
https://ark.intel.com/content/www/us/en/ark/compare.html?productIds=37147,52577,47916

To summarise: Going from the i7-920 drops power from 130W to 95W, raises the maximum allowable Tcase (making thermals less of a concern) and gains 2 cores and 4 threads, along with an 800MHz increase to base clock, and a 530MHz higher turbo clock. You can also make use of faster 1333MHz RAM vs 1066MHz on the i7. Oh and AES-NI and VT-d, which the i7 lacks.

$60?! Where are you looking? It's between £20-£30 on ebay. Check AliExpress too, if you have patience.

Yeah I saw a few for $40 on AliExpress but the few times I ordered something off AliExpress it took over 4 months, so I'm just going to get one off Amazon

If you don't mind a longer shipping time, here's one from HK: https://www.ebay.com/itm/Intel-Xeon-X5650-X5660-X5670-X5675-X5680-X5690-L5630-LGA1366-CPU-Processor/142761996599
