950 oc

just thought i'd post some results in relation to my rig gallery thread HERE

- Idle Temps

- Just under 30 mins of prime

the fans on the thermaltake frio were both set on the lowest (sounds like a wind turbine on high)

1.26 volts, 190x21, 4ghz

for some reason this chip prefers 190x21, rather than 200x20, takes 1.29 to get a stable 4ghz on 200x20 rather than the 1.26 on 190x21.

200x20 is better for ram dividers though dude 200 means 1600 or 2000 ram bang on.

200 is the sweet spot dude BCLK clocks are where its at

 

[hmmblah]

The 920s had issues with even multipliers. Mine was always more stable with an odd multi. Do all i7s suffer from this?

And I agree that 200 bclk is where it's at!

[jamR]

do you reckon its better to have 200x20 and use the extra voltage then?

 

[TMaksimov]

I don't know. Turns out my one likes x21 and x23 more than x20 as well. IMO stick to x21 with lower volts

naaa get it at 200 with the mem tied in correctly. (what ram are you running and what speed is it set too?)

just tried setting it at 200x20 and its still blue screening at 1.28125 v and 1.3v on the qpi, whereas 1.26 is fine at 190x21, will do some more testing later but its not seeming to like 200x20 at all

also its corsair dominator ram set at something like 1607MHz? 8-8-8-24

What is the VTT voltage used ?

What is the VTT voltage used ?

where do i find this?

i have core i7-950 and gigabyte ga-x58a-ud3r mobo and need help with over clocking to just 4 ghz
