7850 black editiion overclocking help

[geeman74]

im currenty at 3.11ghz, 222 htt 14x multi stock voltage,

my problem is if i up the multi it doesnt change in cpuz/amd overdrive stays at 14x in both

if i take my htt above 223 the system wont boot,

ive upped the voltage to 1.4v and its still the same,
could my ram be causing it? i tried upping the ram voltage to 2v from 1.9v but that wouldnt even get to the windows load screen,
got a message saying image corrupt.

would slacker timmings help?

im watercooled and temps are not a problem

im using windows 7

system specs are in sig

i do now booted up with a 225 htt not sure if its stable yet got my core voltage at 1.4v ill run a few tests,
then try upping the htt abit more if its stable

ive just rebooted with a 15x multi and 210 htt 1.376v @ 3.15ghz

cpuz says 15x multi now

just gotta work on overclock whats the max voltage to put through this cpu?
dont wanna fry it

It's most like Cool n Quiet like said, if you up the multi and nothing happens, keep CPU-Z open and hit it with some stress and then that multi will show. Either way I suggest more voltage, the stock HSF setup doesn't seem to have the capability to cool more than 1.4v, so if you can sit a hair under that I would give it a shot. I set my gf's 7750 to 1.4v and the multi up and fired up at 3.3ghz, first shot, stressed it and it worked great, stays on 24/7 too.
