can i fit an intel xeon into my gigabyte g31m-es2l with a lga 771 to 775 adapter

The motherboard can't support a 150W CPU. http://www.overclock.net/t/1431723/mod-lga775-support-for-lga771-xeon-cpus/960 The E5450 seems to be supported with a modded BIOS.

sashankrm,

Yes, as GhislainG mentions, the X5482 is 150W. Also, I did not see any Passmark results for a X5482 on the Gigabyte G31M-ES2L motherboard (435 tested).

However, there is a very good Xeon of similar specifications that is LGA775, the Xeon X5460 (4-core at 3.16GHz,and this 120W :

> and these are not expensive today (10.15):

http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&LH_Complete=1&_nkw=Xeon+X5460&_sop=15

> selling for as little as $20. Not bad, considering it cost over $1,200 new.

The disadvantage as compared to the X5482 is that the X5460 uses DDR2-667 instead of DDR-800.

Checking Passmark, there is one system using the X5460 on the Gigabyte G31M-ES2L motherboard:

Passmark system Rating = 1446
CPU = 4859
2D= 516 / GTX 460
3D=2371
Mem= 880 (4GB),
Disk= 395 (Seagate ST53259629AS)

To put his into perspective, the highest scores for Gigabyte G31M-ES2L systems:

Passmark system Rating = 1933 (Xeon L5420 2.5GGHz, 4GB RAM, GTX 750ti, WD 500GB HD )
CPU = 5335 (Xeon X5450 3.0GHz O/C to 3.5GHz)
2D= 516 / GTX 680
3D=5622 / GTX 680
Mem= 1030 (4GB, on Core2 Duo E8600 system),
Disk= 1999 (Samsung 840 EVO 120GB)

I have a 2008 Dell Precision T5400 using a pair of X5460's :

Dell Precision T5400 (2008) > 2X Xeon X5460 quad core @3.16GHz > 16GB DDR2 667 ECC> Quadro FX 4800 (1.5GB) > WD RE4 500GB / Seagate Barracuda 500GB > M-Audio 2496 Sound Card / Linksys WMP600N WiFi > HP 2711X, 27" 1920 X 1080 and Dell 19" LCD > Windows 7 Ultimate 64-bit >
[ Passmark system Rating = 1859, CPU = 8528 / 2D= 512 / 3D=1097 Mem= 730, Disk= 929]

> This is not a screamer by today's standards, but it runs the programs I use today well enough and has been completely reliable for more than 5 years. The he CPU's then had fewer transistors that were further apart (65nm) and so these do not tend to run hot on heatsinks only. What is very hot running in that system is the DDR2-667 RAM- ouch!- often 80C+.

Your motherboard supports the 135W Core2 Extreme QX9770, but the required microcode is in the BIOS. The 140W Xeon may work, but you need to mod the BIOS and it looks like you'd be the first one to try it. Presuming the system POSTS with the OEM BIOS, it probably won'r run at full speed since it doesn't know what CPU it is.

The following Xeon processors have been tested on your motherboard: X5460 (E0), E5462, E5450 (C0), E5405 (E0) Are you willing to be the first one testing a different CPU?

You can't be 100% sure a modded BIOS will work and not brick the motherboard.

You may need a modded BIOS to fully recognize that CPU. Google "g31m-es2l xeon modded BIOS". The current BIOS may already support all compatible 135W or less Xeon processors (check http://www.delidded.com/lga-771-to-775-adapter/3/), but you won't know for sure until you try it. If it doesn't work at its rated speed, then a modded BIOS that includes the Xeon microdode will be required. http://genius239239.myweb.hinet.net/771/ You really need to do your own research, but it's a nice project and it won't break the bank if it doesn't work. Worst that can happen is a bricked motherboard and a Xeon that you'll try to sell on eBay. If you still need that old PC, then spending a bit more on a supported Core2 Quad obviously is less risky.

The e5450 is also an 80W processor.It's the 1 I purchased for my modding journey. overclock.net is a nice enough site,but 1 moderator having a bad day can ban you for life. There is no due process,appeal,or even a need to have any kind of ck or balance on the bans. I made a TOTAL of 10 post in my time as a member,(2-16-2014 to current) between 5 different threads.My final post was 1 asking for help modding an intel bios.(my FIRST request 4 help) I was banned on the grounds of SPAMMING! So beware if hoping for help there.Most seem nice,but just 1 can ruin your experience. UPDATE! After posting a comment on the overclock Facebook page,my issue was looked @ and privilages re-instated.
