well it only took me several months to finally overclock it! still working on lowering the voltage, but can't seem to figure out why my voltage doesn't drop at idle, instead it drops under load. wth.gif

post #1453 of 6380
Are you setting manual voltage? If yes voltage will not lower when idle. Anyway, I found out when using STRAP & even with offset voltage, the VCORE doesn't lower much when idle. I believe this is to be expected because idle speed is no longer 1200MHz (100 x 12) but higher (e.g. CPU STRAP 125 = 125 x 12 = 1500MHz).

This is my 4.625GHz OC: http://www.overclock.net/t/1221208/i7-3820-overclock/1100#post_17815713

The VCORE drop under load is because a safety feature built in the CPU by Intel which is called Vdroop. It's normal. If it causing instability, you will need to set CPU Load Line Calibration higher.

So i rebuilt my loop Alphacool nexXxus 240 rad (270 long just fits but i had to put the 660ti in the 2nd 16x slot ) ek 1/2 in compression fittings 6 in total replaced the 1/2 in barbs on the 760i with the forementioned fittings . Make sure you use thread tape on the fittings as the thread is nowhere as long as the thermaltake barbs it will leak if u dont doh.gif Hose to suit , fans are Ultima fans 1900rpm x 4 ....... indigo xtreme.....









Still more to be done had to improvise (pegs to get rid of the slight kink tongue.gif ) camera shows how dusty my case is! rolleyes.gif

Here are my bench results............

...and some P95..






I rekon a good 5-10 degrees temp difference.....much cooler i rekon thumb.gif

I'm using offset and strap, but i'll try the settings in the link you provided. thanks for the help! definitely sending some +rep your way! thumb.gif

Dont worry ive got spares! this ones def LN2 worthy , as long as it pulls 5Ghz stable its all good but you are correct , 1.7v starts to kill SB-E chips not recomended i think this one is a freak tongue.gif
