guys..i overcloked my i7 930 to 4Gz on asus rampage 3 extreme..
by default,the option for c1e will automatically disable when i go to cpu configuration tab in da bios..
wat happen if i turn on c1e manually?
nothing bad happen?

i noticed that in HWmonitor,my cpu only takes 40.52W if i turn on da c1e option.and it will keep changing between 40.52W to 115.02W if i do some works.

while da CPUz maintainly show 4Ghz at da core speed tab..

@jerrywan

nothing bad will happend if you disable or enable the feature bro..c1e function is quite similar with EIST..it actually protects your cpu from overvoltage..

if you disable the c1e function, it means that the voltage that was supplied to your proc will be maintain...disable c1e function usually does help in oc..that why most people who oc, they disable that function in order to get their desired voltage..

i see..
wat feature do i hv to enable in order when my cpu is idle,then da core speed decrease..
when i play games,da core speed increase..
i dono la wat its name..
wat u said is i can just turn all da functions?

The feature is Intel SpeedStep Technology (EIST), a power saving feature for lntel processors
it lowers the clockspeed of your CPU when ur system is idle

unbelivable. is this 920 the same 920 that u have been using before 980x? and where's your 980x?

Yes the same 920, but stil couldnt exceed BCLK 220 with this new mobo. I think ive hit its max BCLK at this x21 multi. Can boot 225 but not stable = useless. Might try lower multi. For me, Classified3 = Classified E760 + USB3 + SATA3. My 980X has been sold to someone long2 time ago due to urgent demand.
Waiting for Sandbridge by X-mas as it looked promising...

is sandy bridge available for 1366 socket?

Sandy Bridge is LGA1155. it's a totally different platform

Can I bring my i7 920 over to your house and let you clock to things like 4.6GHz? Lol.. Even with CM212+, anything above 4GHz is too hot to handle.

Maybe you can get a better HSF from Thermalright or Prolimatech? That should work a bit better but it'll still be around the 80C I believe

4.6ghz is imposible for aircooling. The best coud go is 4.3Ghz HT off @ 1.31v touching 88c, with table fab blowing towards pwm

yes indeed get a better air cooler ie Vernomous-X, Megashadow etc... Or H7O. Above 4.4ghz pls get a custom wc hehe.

Perhaps we can also explore the good old phase change cooling If I can get something working, I'd like to have it for my PC That would squeeze another few hundred Mhz more I think?

Old E760 board I have to play more with vIOH, but not necessary for this new E770 - pretty much lesser tweaking

@owikh

can u show me wat is da bes stting for r3e to get 4Ghz stable with i7 930?

i7 920 4.2Ghz(21x200) HT off

Max temp 78c and idle 55c
The RT is the new temp as the temp when linx test was finish TERclose
Thanks bro owikh for guiding me.

i7 920 4ghz(20x200) HT off

U might try to ask BigSaver below


Well done mate, finally. woot Golden batch spotted 3849B056
The temps still allow u to clock higher.

wahh..he actualy can do 1.20v for vcore??

for that batch, it's a piece of cake for 4ghz. but still not sure if the IMC is good. Coz I owned one before

@Bigsaver
what ram ur using? if it's capable of doing 2000mhz, please try to run it with 4ghz uncore and see if u can pass prime95 5.4gb
