Just emailed customer support but I figure I may get a faster response here.
I have just bought a new old stock E756 and would like to use a Xeon L5640 on it. I have read numerous articles and even got this processor working on rev 1.0 E760 and rev 1.0 E762 as per Shamino's instruction to short 2 areas.
Also, the current board is rev 1.0 E756 with totally a different layout than the 2 models I mentioned previously. I have tried updating the BIOS to the latest 82 using a Nehalem based processor but still the problem persists (FF straight away upon powering up). The board is definitely not faulty as I managed to run Nehalem based processor on this board + updated the BIOS.
I believe this may have to do with dual QPI links of the Westmere EP and the way to solve it; is via similar ways (shorting pins, etc.).
Anyway willing to assist me? I don't mind to do the soldering and voiding the warranty is also fine by me.
Thanks very much in advance for your help.
