Sandy Bridge OC results

post #1 of 40
Thread Starter 
I just put a noctua D14 in my rig, i am running my sig rig with i5 2500K.

This what i have so far.

x46 Multi @ 1.350 volt = Stable prime 95

x48 Multi @ 1.350 -1.365 = FAIL ( Tryed going up by .5 and stopped and posted this thead at 1.365 before continuing)

How high volts and what other bios settings do i need to change beside these 2 to try get it to 4.8 stable?

Keep in mind i want this to be a 24/7 OC, I know all chips are different so what would you guys recommend not going over on volts for a safe 24/7 clock at 4.8ghz or am i at my limits ??

na u not at u r limit or anythin. it just need little more voltage
usally these boards have droop .
so u need to see how much decrease of voltage is there on load .
mostly above x46 u will need to enable Load line caliber to levl one
and be carful if u r enabling to lvl 2 coz there is big jump in voltage

and is 1.35V , the voltage at load ? for 4.6 ghz . its pretty decent
for 4.8 u might need about 1.38V at load .. try that and decrese the voltage till u r sytem crashes ; then optimze it

keep a note of temp at load too .. 85 is safe but not for regular use 24/7 keep it below 75.

use the latest cpu -z or gigabyte ET6 or somthin usally u hav problem readin the voltage on the new boards .
use PLL to 1.80 not more . later once u get a stable boot then u can decrese to 1.76 or somthin dependin where u can stablize u r system

Lowering PLL voltage to somewhere in the lower 1.7x range will help. My board can't go lower than 1.80v though . But your vcore is technically safe up to 1.52v.

When i run CPU Z, under 100% load from prime 95 it tells me my volts at 1.068 V

But my volts in bios are set to 1.350 to get it going stable ?? @ 4.6ghz

Another update im at 1.45v and its stable so far in prime 95. I jumped from 1.42 to 1.45.

How long should i run prime 95 for to decalre its stable enough to start trying to lower the volts ??

cpu z is showing wrong voltage , probaly B3 boards are not supported yet ..
decrese your voltage and enable load line caliber to levl one
and tell me your setting
1.45v is pretty high for 4.8
u will need only 1.4V

are u using load line caliber ? check your voltage using easy tune 6

Not necessarily, it depends on his luck of the draw. My last 2500k took 1.46v for 4.8GHz.
