Bunk 5000 BE: ADO5000IAA5DS NAA9G 0746DPOW.....this one was baaaaddddddd! 3.0ghz at 1.35 and nuthin over that new 5000 BE: ADO5000IAA5DS NAA9G 0805FPCW.....this one 16x multi, 1.4vcore boot right into windows no problem Besides the bolded CPU numbers..I noticed another MAJOR difference! In Everest Ultimate Edition ver. 4.20.1294.0 ......................on the bunk 5000 the CPU Core #1 and Core #2, I saw temp differences of 10-15C............on the GOOD 5000 I see a max difference in Core#1 and Core#2 temperatures of no more than 3C !! [I noticed this difference in the Core #1 and Core #2 temps BEFORE any over clocking was attempted.] So for all you overclockers who would LIKE to RMA bunk 5000's......BEFORE you overclock....check the Core #1 and Core #2 differences.....because once you overclock them at all....you VOID the warranty and the RMA process. THAT seems to be the most telling thing I've found so far. This new 5000.....set 16x multi and 1.4vcore and it booted right into windows no problems. On the BUNK 5000...set 16x multi and 1.4 vcore and BSOD so hard, its fortunate I have a crash free BIOS ! If I notice any other differences that would tell us BEFORE we overclock...if we had a good overcloking 5000 BE....I'll post them here.
