Been trying to follow a guide and the settings in the bios don't match up
to mine in the sabertooth bios.
Tried looking at all the guides on the net and they all seem the same.
Any help would be most welcome.

cheers ant.
 
Hi, would like 4ghz
spec as follows-
i7 950
sabertooth x58
corsair dominator ram 3x2gb
corsair ax750 psu
noctua dh-d14 cooler
600t case.
 
I like to clock through cpu offset but its down to you really

id only alter three main voltages qpi/dram to 1.35v

cpu offset depends on each cpu so maybe +0.0750v

and dram voltage id set according to your memory either 1.5v or 1.65v

then set the cpu multi and bclk to give you 4ghz

so maybe 21x191=4.2ghz

then 8x ram multi to give you 1528mhz ram speed

set uncore freq to 16x

stress cpu and look in cpu-z to see what the load cpu v is,and adjust the cpu offset to raise/lower the load cpu voltage

stay below 1.4v and below 80c if you can

ideally around the 1.35v mark but again depends on the cpu,some like more/less voltage

ohh and disable intel turbo boost so it doesn't boost past 21x cpu multi
 
uncore should be 2x your dram speed. Ie, 2x 1528 = 3056, though it will likely state 3057 iirc on theese boards. This is still fine.
 
Settings used thx wazza,

ai manual
cpu ratio 21
bclk 191
dram freq ddr3-1531Mhz
uclk freq 3063Mhz
cpu voltage 1.3
qpi/dram core voltage 1.325
dram bus voltage 1.65

prime95 large fft's 30 mins all ok.

max temp 81deg c, core 0
 
That guide I was reading, was saying to "Testing for highest stable bclock frequency"

I liked the sounds of doing that way but lost the plot with ram timings etc.

I would like to understand it all, I just must be thick lol
 
looks good to me,does cpu idle/lower volts?

should do if you enable all power saving except c1e as that usually causes whine on x58,cpu will throttle at idle aslong as you use balanced power profile in windows without c1e enabled
 
did you set cpu offset to +0.0750v?

enable eist and c3/c6 power saving in the bios and pick balanced power profile in windows power saving options

should lower cpu v to less than 1v at idle
 
yeah that's it,im only guessing at +0.0750

what cpu voltage does it give you under stressing in windows? just keep your eye on it and adjust offset if need be
 
try touch more offset,maybe two clicks more and try 1.37v dram/qpi voltage

usually memory if it fails blend, qpi is for the integrated memory controller

most chips need around the 1.35v cpu voltage mark for 4ghz,4.2ghz unless you have a golden chip
 
Can get it, stable at 4Ghz but the noctua d-14 does not seem to coping very well with the temps.
80 deg c to 85 at v/core 1.336v. Tried reseating it today with less tim, still no joy.
3.8Ghz is easy, with temps in the low 70's, might stick with that.
 
Got 4Ghz stable now, but as soon as I put LLC on it just cuts out and restarts the pc, strange.
Wonder if its psu related.
