I got the same batch i7 from buy.com(ebay store), same memory, almost same mobo UD5 running at 3.8Ghz HT ON with CPU : 1.3V and QPI : 1.3V, Mem: 1.64V (7-8-8-20), temperatures are way high since I am on Stock Cooler. Scythe Mugen 2 is on its way.
I thought 3841A431 would have made into 4Ghz under 1.4, but I guess I am wrong.
