I am fallowing this guide. I am still no sure if having vcore above VVT/IMC Voltage or vise versa. Who knows looks like this guy chose Vcore over IMC. I am running prime95 now. will see what happens. In past I have had 1.35 VCORE/1.35 VVT run good for 18 hours than failed. This is were I get lost what to add??? Bump IMC or vcore. None really gave me a clear answer.
anyone knows what in blazing going on here?? Why cant I run windows7 index rating. http://img257.imageshack.us/f/29287584.png/ I tryed manually doing it through control pannel, but no go! Nothing happens. Antivirus is disabled.
Wait a sec, I think there's been a bit of confusion as to what is going on here. As said before, you will more than likely need to have 1.4V on the core. The IMC, you're looking at 1.3V or so. My advice now though, bring the clock of the processor back to stock, run P95 again with the IMC at 200MHz, and start the IMC voltage at 1.2V or so. Once you get that stable, bring the multiplier up to 20x, then keep upping the voltages there until stable. Also, set CPU PLL at 1.8V.
ignore windows index rating as its rubbish anyway but yeah you wont find an exact guide as overclocking isnt exact. what works for 1 may not work for another. its a guide not an instruction set. its all about the trail and error. try upping the Vcore a bit more and re-test. if it works job done if not revert it back maybe try the IMC with a little bump. still not working try more Vcore etc etc
Is 82C full load little on the high side? Because it seems to be stable @ 1.366 Vcore/1.35IMC http://img814.imageshack.us/f/98951685.png/
and you wont hit as high of temps under normal usage as you will under prime. 82 is kind of toasty, but should be OK as long as you arent hitting it regularly.
I ended up using 1.38 vcore hope it's not high and 1.237 on IMC. Thank you all people for your help! Glad to know 80C is ok
It won't do it any good if it spend a long time up there. Just because it can theoretically run higher doesn't mean it should. I'd keep temps below 70 if I were you.
they probably will be below 70 for normal usage. your temps will never hit as high during normal usage as they do during prime95. when i messed around at 4.0ghz, mine would hit 88 degrees under prime...but hovered around 65 while gaming.
yes. anything can/will become unstable when under volted...but why would you? RAM doesnt produce much heat.
the memory controller is made for "low voltage RAM", which is 1.65v and lower. dont go sticking your 1.9v stuff from your old socket 775 board in there. if your RAM is rated for 1.65v, its best to run it at that, even a little higher if you plan to squeeze more out of it. the G.skill RAM im running is a 1.5v kit that ive been pushing 1.6v to. i managed to get the not-so-hot rated timings of 9-9-9-24 2n down to a slightly more respectable 8-9-8-22 1n, still at 1600mhz.
Awesome! That makes me confident knowing that. Just been little worry. You know seeing how Asus manual clearly says 1.5v and all. Defiantly will give it a shot now though. And who knows maybe, just maybe it will even let me get away with 1.35 Vcore and 1.25 VVT @4.0GHZ 24/7 stable! Thank you! + rep dude and everyone that helped.
funny that asus says anything about the memory voltage since the memory controller is no longer on the motherboard, its in the processor die. good luck and have fun tweaking it. just remember to be patient and youll get it figured out eventually. let us know if you run into any more problems.
