OC a i7 920 with 1066 RAM

Why shouldn't I leave it on auto? As I'm playing around the same ballpark for volts arnt my temps going to be too high anyway?
 
Yh you could,I thought you wanted to bring it down from 1.36v sorry,you can try and improve on auto though maybe 1.31v ect its Upto you really

Anything below 80c,odd spikes to 80-85c is ok but not constant
 
I would like to bring it down if it improves temps, just wondering if it's going to.

Thanks for your help btw, much appreciated!
 
Yh to take off voltage from what normal sets you use minus dvid so try -0.0100v which would be 1.31250v at load,makesure its not crashing due to not enough qpi/vtt voltage aswell,CPU v might be fine?

Hence the bsod codes above followed by a series of zeros
 
It crashed with +0.0100v in the dvid. I'm running +0.0500v right now. Where can I read the BSOD codes if the screen disappears fast? I'm looking in Event Viewer but not 100% sure what I'm looking at.

I'm about to run prime with +0.0500v, I'm expecting crash.
 
+0.0500v makes 1.3625v ? If your stable with 1.3250 then that's too much,try leaving dvid on auto

Edit,you might need more voltage then if prime95 failed,Idk if its worth pushing as temps might be too high?

I think I've messed up my few attempts at changing the dvid. Do those changes only apply when you enable 'Load Line Calibration'.

I caught a glimps of a 124 error on my last BSOD.
 
Well its personal choice whether you wanna use llc or just add a touch extra in dvid,both work the same way in raising load voltage to compensate for vdroop

124 is not enough qpi/vtt,try with 1.32v qpi/vtt and just set CPU v to normal,leave dvid on 0.0000,try that
 
I've just tried

qpi/vtt 1.32v
CPU v normal
dvid AUTO

It BSOD with the following:
BCCode: be
BCP1: FFFFF880004FAE60
BCP2: 0000000192E80121
BCP3: FFFFF880009A9A30
BCP4: 000000000000000B
 
I don't know what those are sorry,it still could be CPU voltage now,try to test with increments of dvid +0.0100,+0.0200v and so on,I'm sorry its such a pain to get right but you will get it right,some chips use little some need more voltage
 
When I try the next dvid of +0.0185 I get errors in Prime. I'm not sure what to do next, it seems the only way I had it stable was to leave the CPU V to auto but then the temps were a little high. Having said that nothing in everyday use is going to stress it the same as Prime so it should be ok really.
 
I'm in a similar boat: Intel 920 never overclocked.

And have decided I might as well give it a go now I'll be upgrading soon...

Idiot guide for:

Intel i7 920
Gigabyte GA-EX58-UD5
12 GB DDR3 Ram 1333
OCZ 850W PSU

What could i get out of that spec?

Each chip is different it's trial and error. What CPU cooler do you have?
 
It depends on the CPU,12gb would need more qpi/vtt than 6gb

I've had 3 920 cpu's,one needed 1.23v for 4.2ghz and the other two needed 1.35v and 1.36v,I only tested with 12gb of memory once @1600mhz and stock CPU clocks n I needed 1.3750v qpi/vtt

I'd start with 1.35v for CPU and qpi/vtt and work from there
 
Just BSOD on me (after about 15 minutes Prime) with CPUv to AUTO (dvid and qpi/vtt also reset).

Not sure what to do from here. I thought 3.5Ghz was a mild overclock for a 920.
