Hey Bino !

I have the same issue, it's seems to be a wall for me at FSB > 1870
Tried 311 (best bios for me), 404, 601

(445x9) vcore=1,625 loads windows, but not stable, needs more vcore

(450x8) with vcore=1,425 can play games etc but prime95 fails fast, i guess it needs like 1,5 to be stable

(500x7) vcore=1,425 NO CORES, on everest, coretemp, etc (fsb=2000)

(463x7) vcore=1,325 STABLE (fsb=1852)

(500x6) vcore=1,3 NO CORES or BIOS just hungs, tried all and no go...


The best OC's for now comparing memory bandwidth, temps and speed and all was:

(463x7) 3.24Ghz
vcore=1.3250
1111 (5-5-4-9) 2.2v
(NB=FSB=1.4)
(temps shown are whith the cpu lapped and seconds after prime95 finished)


Very fast config, low vcore, low temps and very good bandwith

(425x8) 3.4Ghz
vcore=1.40v
1020 (4-4-4-12) 2.2v
(NB=FSB=1.4)
(temps shown are when it wasn't lapped and seconds after prime95 finished)
