i believe it's d other way round. d higher d imc freq, d more stress it'll get, hence, mem freq will be hindered. i could be wrong thou. d thing is, one must balance d two, there's no point having high freq in one while low in d other.

CPU-NB voltage set to auto...currently it shows 1.49-1.50V
Yeah i mean higher cpu-nb will improve performance (oc result not oc process )

thx for ur input

what dato' kunta means was this
on aida64, click tools>cache and memory benchmark

click start benchmark. then look at memory score (read write etc)
compare with other setting

vdimm at 1.75v is much more safer then cpu nb volt at 1.5v. even 1.35v is consider high for some.

so better pump up vdimm and tune down vIMC.

@lengchai

yes2.that one. long time havent use aida so fogot already.
thanks

btw when you set 8-8-8-24-1T @ 1540GHz, what is your ram voltage. 1.65V?
i think cpu/nb volt at 1.49V-1.50V is a bit high

thx lengchai86 for your super fast reply ..will do it now

EDIT: ram voltage=1.5V

Added on February 3, 2012, 5:29 pmWill do it...trying to lower cpu-nb and raise vdimm thx

Added on February 4, 2012, 4:34 pmI have instability issue (BSOD) when i change cpu nb volt from auto to 0.5(1.17v)

So i started oc from scratch:
1. CPU-NB + RAM oc (STABLE)

CPU 3400Mhz auto
fsb 255
RAM 1700Mhz 1.6V 9-9-9-24-1T
CPU-NB 2550Mhz 0.15(1.277V)
NB 1.275V
HTL 2040Mhz auto

2. CPU + CPU-NB + RAM oc (STABLE)

CPU 4032Mhz 1.46V
fsb 252
RAM 1680Mhz 1.6V 9-9-9-24-1T
CPU-NB 2550Mhz 0.15(1.277V)
NB 1.275V
HTL 2016Mhz auto

Will try to play with timings when i have time soon...

when you set the cpu/nb at 1.17 what is the speed of npu/nb then..

quote from here

Ooh my bad...the cpu/nb was 2758.7MHz
actually at same cpu/nb was set to auto (1.49-1.5V) but bro kuntawakaw said it was too high so
i tried manually set the voltage by adding 0.05V cpu/nb offset (1.17V)

1.17V for 27XXMHz is very low. 2700Mhz i think can set around 1.27-1.28V according to the link that i attach there.
indeed 1.35V for cpu/nb is consider very high oredy.

last time mine at 2500Mhz need at least 1.26V iinm

Agreed...my 0.15 is border to red indicator in bios which a warning for overvoltage imo

did you manage to oc part by part?
1.finding max fsb
2.finding max cpu
3.finding max ram clock speed
4.finding max cpu-nb speed/imc

1,2,3 yes i only find for this 3. then i find optimum for this 3 part because number4,
higher is better (2700MHz is consider high oredy) mine only 2500Mhz

ok then did you know about Dolk's guide?

have read once last time. but i lazy to study in detail, i just read to have a basic step. then i ask in the forum to get direct answer
