Can't stabilise at 4.2ghz! gah.

post #1 of 7
Thread Starter 
4ghz was a breeze, just threw on 1.290v QPI and 1.28vcore at a bclk of 191 x 21 and it passed prime 12 hours and IBT 100 passes with ease at around 65C.

However, I can't for the life of me get it stable at 4.2ghz (191x22).

All the way up to 1.4vcore and 1.330v QPI it still gives me the same error code '0x0124' again and again. All power saving features are disabled. Could it be my RAM isn't happy with this high an overclock or something?

Could modifying CPU PLL and/or CPU PCH help me out here? These are on auto at the moment because I'm not entirely sure on what role they play in overclocking aside from something about the southbridge. I have played around with these voltages a little, set the PLL to 1.880 and the PCH to 1.14 but still had no luck.

Please help!

try raising your ram' timmings a bit. it should help.
go for 9-9-9, or 9-11-9

I've heard people say to use odd numbered multipliers only with these CPU's.

I have no idea why, but it can't hurt to try I suppose.

Alright, thanks, I'll do this next time I try, probably when I get a couple more suggestions.

use 21x200 you will have much better luck that way with less voltage too. i would guess around 1.32-1.36v give or take

I tried this previously and still had no luck.

I guess I could try it again later on with looser ram timings as suggested, however.

how was the other voltages? if you told us what all your voltages were we could pinpoint what needs to be increased. also any blue screens will also help. ( we only need the BCCode )
