Default EVGA x58 SLI LE rev 2.0 Westmere modification

Does anyone have a picture of know the numbers of the plugs to cross on the EVGA x58 SLI LE rev 2.0 (E757) to disable the second qpi so Westmere-EP CPUs work?

I can only find info on the E758. Any info at all would be appreciated. Thanks.

You Sir, are a gentleman and a scholar. Thank you very much.

Turns out though the rev 2.0 supports them without the mod. Long as you have the latest BIOS (currently 83)

I replaced my i7 920 @ 4.1ghz with a Xeon X5650. Just got it today so have not had a chance to really test it but currently clocked at 4.2 with a max temp of 51c under full load. Very impressed with it.

Got it off ebay for 70 bucks....

You have to do that with the E767 (X58 SLI3) rev 1.0 (rev 1.1 and 1.2 work fine) for sure, confirmed with the EVGA tech support two hours ago. Can't say that for sure about the SLI LE, though.

But there are no such elements near U20 on my board, nor can I find a dot labeled "36"? It's an E767 rev 1.0. Is there only one U20 element on the board?

Well I seem to have found the spot next to the IOH, now the one above the CPU socket matches with one exception: the 8-pin chip is labeled U23, not U20. Is that the correct location?

Also, can you please post some schematics that would explain how this disablles the second QPI, as well as why it is required to disable the second QPI?

No schematics, sorry.
It's just a strap signal. Why it is required, I don't remember details, but probably because primary port is second on CPU or something like this.
