E4500 OC hit a wall

[Ashcom]

First time posting here, just after a bit of help. Currently i cant get this chip past 2750 MHz without getting a BSOD. Currently running stable at the following

FSB 1000
CPU volts 1.28
FSB Volts 1.3

Memory I'm using is OCZ 5400 DDR2 unlinked running at 667MHz not messed with the memory or timmings at all, all this is running on a EVGA 650i Ultra. Any ideas guys?

Well you'll need a high cpu voltage. Whats vdrop + vdroop like on that motherboard?

I always forget exactly with that board, but IIRC you need to run the ram linked and synced. FSB voltage at 1.5v with a fan. CPU might need 1.4v for 3Ghz.

And Welcome to the OCUK forums.

Thanks will try this tomorrow after work. weekend project is to lap my Zalman CNPS7500-CU or try to. The size and weight of it may cause a few issues but can't hurt to try... well i hope not >.<

Im running one as well, and cant get it Orthos stable (fails after 5 seconds) above 2.8ghz on a P35C-DS3R. Interesting...

My 650i had an FSB hole around there, between 300-350mhz FSB. Just dropped the multi to 8x360 and it booted fine at 1.325v Orthos stable.

FSB now maxed at 1.4v
CPU core at 1.3v
FSB spd 1060
CPU speed 2915Mhz and 6 hours stable on Orthos

getting there slowly, soon as i max the CPU gonna start on the RAM
