3.6gig already touched 70C on priming then again I have high ambient temps due to global warming and no a/c. Gonna try reduce some voltages and see how it goes.

haha.. that's too bad... while you wait for your ram you can get other cheaper ram... I didn't know the lousy Kingston can go up to 500fsb... interesting
but to wait for that long for rma is not that good to risk it.. unless I have some extra money..

tested with my dominator 1066 rev 4.1 2gb kit X 2 at 1.9v

is the vcore high? is the temp high? please advice..only manage to oc to this after pump mch v to 1.22v

Last nite i was bored and start OC my QX6800 and push it to 3.6Ghz with 400x9. After prime it, the temp go to 73c max, dono will spoiled it or not hahhaha.... any comment everyone? i am using deep cool killer whale already with cooler master fan....

the temp is ok and i dont think u need to worry bout it.

i push my QX6800 to 3.6ghz oso but with 450x8. while prime, temp go to 82C-84C! no prob at all.
using CM V8.

er whats ur vcore in bios setting?

May i know the reason your use 450fsb for higher fsb? is it better bandwidth? what about the voltage setting in your bios? i think i put 1.375 in bios but appear at cpuz only 1.312....... is this normal?

i think thts normal,im using 1.365v in bios but cpu-z shows max only 1.328v sumtimes lower

Yeah noticed board BIOS and CPU-Z timings have a pretty big difference.

1.34XXX

dropped by mch core to 1.2v only..passed orthos 6 hours yday...in 32bit and priority 1...

Does anyone know what's the max 24/7 safe VTT for 45nm CPUs? Can't seem to find it, unlike vcore 1.3625V and cpu termination ~1.38-1.4V.

Also, given an ambient temperature of 34C, should I get a better cooler or get an a/c set up? Current cooler is a CM Hyper212, idle/load at 48/60 assuming tjmax=95 at 400 FSB.

my e8400 520 x 8 @ 1.356v also almost same temp with u.but the thg with mine is tht it require more than 1.4v on the mch otherwise it wont boot up

yup, higher bandwidth. better, use 500fsb but needed 1.4v on mch core. (now use 1.22v)
can u use strap 400 with 400fsb?
1.375? for vcore? i only use 1.337 for 450x8. yup, it's normal. mine oso like that.

perhaps i wouldnt noe until i pass 500fsb? will spend more time on it...

but ur vcore, 1.356v, is it on cpuz or windows?

ur ram performance level? standard or turbo? if ur ram kenot tahan set to standard lo..lol...

the problem i hav now is time..hopefully 2molo can clock more...drop multiplier...

wat do u mean by 1.22v? cpu? then how come u say 1.337 for 450? very confusing... hahhaa....

wat is strap 400 with 400fsb? 1:1 ratio? if tats wat u mean then yes, my current setting is running 1:1 which is 400:400 n cpu is 400x8 with 1.375 at bios there else the system will not prime stable....

u should keep the vtt below 1.35v for 24/7 usage. it been said that more than that will kill the 45nm processor.
and the tjmax for 45nm was 100.

How about my qx6800? wat is the safe voltage range for it?

1.22v is my MCH Core @NB voltage. need to pump a little if u're pushing it further (OC), if not, pc wont boot or "on n off repeatedly".

1.337 is my Vcore for proc. 1.22v for MCH Core (voltage for mobo).
u'll get 1:1 ratio if ur fsb is the same with ram speed. not strap.
strap oso called MCH latch. u can pick any n it'll show u different speed depend on strap that u pick.

the best bout qx6800 is, it's 65nm proc hence can put higher vcore than 45nm. but as always, heat is the prob.

i leave tht as default which is turbo
