My i7 overclock

post #1 of 11
Thread Starter 
Who would have known that switching to a 200 x 20.0 overclock to a 182 x 22.0 overclock could lower your load temperatures by almost 10C, due to less voltage at least.



I will probably do 20 runs later on tonight just to make sure it's stable...but overall, I am quite happy with my new temperatures

Edit: Forgot to add that before (at 200 x 20.0) my highest core was 72C

Now all I need is some ram that will do 1800Mhz....

Most Intel iX series chips like an uneven multiplier - I would go with 21 x 191, you may find a little more stability with a slightly lower vcore, just my 2 cents though

So, just an update for anyone who may be following this haha...

I took appleg33k85's suggestion and changed to 21 x 191 and lowered the vcore to 1.3V in the bios:



Now to slowly lower the vcore until it fails

thanks, appleg33k85!

thats with i7-900/1366 chips
all my 1156 quads and dualies seem to like the even multi's as much as the odd ones

OP:the reason you need less vcore and is because almost all cpu's require less vcore using their stock(highest)multipliers.like my i7-920 could do 4.5GHz w/1.34v at 21x215 but when i ran at 19x230@4379 it needed 1.39v vcore.

LMAO you were running a i7-920 at 4.5 ghz with what kind of cooling rofl I cant get my I7-950 to go above 4.3ghz with nothing less than 1.4 volts.. seems a little strange and im alamost positive I have a better Cooling setup unless you running a custom w/c loop on that 920 as well.

You have a rasa block and you're still at 72C? What radiator are you using?

Now that I think about it...I don't really feel much hot air, or much air at all for that matter, coming off the radiator. I think some AP-15's are in order.

your loop might be better than mine,but i use my AC with vent hoses going to my rad and my computer
5c air so my temps are always in check and good.with my 920 at 4.5GHz HT ON w/1.32v it never went above
60c under full load(LinX)and with my i7-970 at 4.5GHz HT ON w/1.36 it barely hit 50c under load

right now my x3440 at 4.0GHz stays under 40c under full load.
its amazing what an airconditioner can do to keep temps in check
