Would a W3570 LGA 1366 CPU work on a P6T Deluxe motherboard?

First I would like to say, I know it's an old motherboard and an old CPU. I had this board since ~January 2008 and still have a i7 920 CPU in my P6T Deluxe(v1). I recently stepped on a W3570 for 75$ so I bought it after reading a bunch of forum threads about Xeon processor compatibility with normal motherboard. On some forum it says they done it and there's no problems and on others it says you cannot run a Xeon core on a normal board.

Now what I would like to know is, did anyone ran a Xeon cpu (lga1366) on a P6T Deluxe motherboard without any problems? If you had any problems what were they?

I saw one guy who said he had some voltage problems (but he wasn't on a P6T deluxe) which caused his CPU to heat up to 80c. I don't worry to much in my case, I have a Hyper 212 EVO cooler on my CPU.

Hope someone can help me :)

Your CPU is okay with that motherboard and it's socket. You should be able to get it to work.

Many LGA 1366 motherboards are specified for Core i7 processors in the 9xx family, but do accept one Xeon, a Xeon W3520, but not other Xeons, hence not a W3570.

ASRock's X58 Extreme model may be the exception, in that it supports W35xx processors of all variations, and a number of others as well (see complete list, below).

Acceptance has to do mainly with the CPU support code which the motherboard manufacturers have incorporated into the BIOS. And, in some cases, in it possible to add to that support database, which involves modifying the BIOS image itself and then re-FASHing the BIOS.

The Shuttle X58, for example, will not accept a W35xx processor, but it will accept any Core i7-9xx processor.

The Gateway FX6800 motherboard, which is really an ASUS X58 motherboard made for Gateway, for example, even accepts extra-low-power Xeon processors in the L55xx series.

Here is the support list for the ASRock X58 Extreme motherboard:

Core i7-9x0
Core i7-9x5
Xeon E550x
Xeon W35x0
Xeon W6x0
Xeon X55x0

And, I could infer, by extension, the Xeon E55x0 and Xeon L55x0 as well.

Thank you Peter. I would guess the P6T Deluxe(v1) is also an exception like the ASRock X58 Extreme because my W3570 as been running for a month and is absolutely fine. I performed some benchmarks and stressed test the CPU and it ran perfectly and was correctly recognized by my PC. For 75$ it was worth it in my humble opinion.
