just join the club..
i5-3570K,Asrock Z77 Professional M,Vengeance 1333MHz 8GB,H70
now using stock only,just set up my rig....
so far temp idle initial cores varies 37~38c only but CPU temp is 52c

i've gone thru 26 pages of this topic..normal isn't it?
wonder if OC 4.6GHz how high will it be?

*ram i revert from 1600 to 1333MHz coz CEX no stock for Vengeance LP 1600MHz
coz my clearance in TJ-08E only 54mm....will it hold me back to OC cpu to 4.6GHz?

try OC my i5-3570K with 4.5GHz offset +0.010V (Vcore=1.208-1.216v)
be4 got BSOD with x1A error which is not sufficient dram voltage...
after lurking around find out my ram running 1.585v in default/auto in BIOS/UEFI

then i set up dram voltage=1.585v
everything goes fine untill 1 hour++ prime95 got fatal error in prime...but none BSOD occurs..just 1 core stop working....anybody?

i think so... acting like i own a golden chip la plak...
i'll bump +0.015v now....
1 thing is it ok 1.5 ram running 1.585v?
stated here scroll down by lingloong this 1333MHz ram easily run 1600MHz,but may b possible with 1.585v
later i'll test after cpu stable...

glad to hear that..
u foresee my next question..hahaha
wats the point having it stated 1.5V while it works over tat btw....hehe

ok after ~1hour+ blend test of prime95
here's the screenshot of CPU-Z,prime95,real temps,AiDA64 temp readings

btw all temps readings varies..so which one the most accurate?
my references webpage for OC obtained here: (coz here mostly Asus users,me budget user only )
Ivy Bridge complete OC guide ASRock Edition
ASrock Z77 discussion club

btw owikh last nite whenever i set my dram voltage to 1.5v with default timing 9-9-9 24 1N BSOD occurs
in my board it considers undervolt (with sufficient voltage) coz by default it runs 1.585v
i run memtest86 last nite for 2hours45minutes++ and confirm none of the stick have errors.... (waiting memtest finish i can sleep for a while hhahaha)

Added on July 14, 2012, 3:07 pmmeans if dare enuf can try OC ram rite..but on own risk...
i'll try 1600MHz later,1866 afraid fry my ram
btw owikh count me in....here my cpu-z screen

erm from here bro;
http://www.overclock.net/t/1198504/sandy-i...-asrock-edition
click on HELP ME then BSOD LIST
1st upper column quote from overclocker23578
bottom column is urs...
dunno can rely on this BSOD list or not
aiyak my bad this code under sandy bridge...erm how a?

This post has been edited by huzzLEE_82: Jul 14 2012, 03:30 PM

here my BSOD screenshot, 0x0000001A error when dram=1.5V

never occur when dram=1.585v (guess my ram need 1.585v instead of 1.5v)

btw OC terms in Asus and ASRock i think not similar (dunno,just random guess)
i try bumping ICH voltage & VTT
VCCIO=VTT=QPI=IMC
but for ICH voltage not sure which one? mr google not helping much

yup +1 my ram the culprit one...most probably
btw i make an adjustment,LLC to level 2 (b4 level 3) cos i think the 50% compensation not doing much encounter with vdroop on Vcore
so ur LLC on which level bro?
from my readings,level 1 will spike Vcore really high during load...

sigh 7 hours plus prime95 ends up with 1 worker stop working....(offset +0.055v)
now bump +0.06v but after 40 minutes plus worker no 1 stop working....
anybody knows what indicates this? either than Vcore not suffice....

now i bump offset +0.065v (up to +0.07v now)

orait owikh....in prime not using blend test as it test on ram a lot....
i put large FFT....
now running prime 95 with task manager tab....i'll do linX...but need study 1st...
never use b4..tq owikh

hmm now revert back to stock speed...stock default BIOS setting...
running LinX (select all tab next to memory column)
after 3 minutes here wat i got:

crap with default value still fail....must b my ram stick..but few nite ago i run memtest86 almost 3 hours error is none....

bereh boh...

now here's the latest story.....or is it something to do with SSD tweak optimization?
i remember several setting changed up b4...

hehehe no offence here...i'm not tat kind of fanboy of any brand...b4 i use Asus...this time budget nipis..so shift to ASRock..
btw seems like i got a stick faulty...might b...
i tested a stick at a time..on the same slot....
that particular bad stick (hopefully "bad") seems kenot stand LinX more than 1 minutes++
also kenot pass memtest 0.2% test...
then i do memtest 86 again ....bad stick got lots of errors....
hopefully i trully capture the culprit....

last time memtest86 done with both sticks attached to respective slots....
tq owikh..kenot imagine if u not here in LYN...tqvm again...

Google has a lot of reference website...surf around and do read a lot about OC..then oldtimers here will gladly help u giving tips and advise

btw RMAed my ram before..and i've done with memtest86 and memtest....
later on i do LinX for 100 runs (4 hours 12 minutes 38 seconds) with none errors

now doing prime95 blend test.... anyway which 1 is more reliable? prime or linX?

ok i think i'm done with stress test
running LinX for 4 hours++..i think suffice enough
btw here's the screenshot (same as before)


then i do prime95 for 12 hours....so far well maintained Vcore=1.216v which is very gud i think
here's the screenshot..i think can push higher but i'll keep stagnant at 4.5GHz for now coz no time testing..also very lazy and buzy...

thanx to owikh84 for sharing his knowledge....

tenkiu owikh...but mine is nothing compared with urs

Added on July 27, 2012, 8:23 ami never use i5-2500k before.....
mine 4.5GHz on H70 max is 92c with LinX / 80+c with prime 95
which is for my personel preferences is acceptable since TJmax for Ivybridge is 105c (100c for SandyBridge)
*i replaced my stock 120mm Corsair H70 fans with Artic Cooling 120mm PWM fans

Added on July 31, 2012, 8:44 am2/8 gb RAM stressed..
he means u just stressed out 2GB out of 8GB ram capacity
ram if possible try 90% or above stress test because we need to test IMC inside CPU.. (this is wat owikh84 told me b4...i just repeat..hehehe)

see post #620 (page 31) by owikh (regarding IMC)
try LinX bro...it really put ur cPU under heavy load which is the temp is around +10c compare to optimus prime95 hehehe...gud luck

before i run prime95 7 hours plus untill got error (1 worker stopped working)
with LinX i just need to run it for 3 minutes then got error....

it depends imo...
hmm in my case LinX proven 2b better..after i finished 100 run (4 hours++) of LinX..then i proceed with prime95...
for starting i put offset +0.005v all tested with LinX then up to offset +0.020v
i can see the pattern of failure (longer time taken before LinX got error) 30mins,42mins,1 hour++,.....untill 4 hours plus done for 100 run
then i did prime95 and it can last for 12 hours....till i end it with none error occurs

in before during i had a faulty stick of ram...i've gone thru 7 hours plus with prime..but LinX detects that error within 3 minutes (as told b4)
i'm not judging linX is better coz i'm no pro..hehehehe

a little update...felt bored during public holiday...
running my 1333MHz ram with 1600MHz...dram voltage 1.5v
test up with LinX for 100 runs...completed with none error...

(during test screenshot i missed to save coz slept waiting it finished)

try 4.6GHz but 101 error occurs..needs more juice...
later if go better cooling solution i proceed...
