You should just enable all 4 cores and start slowly taking it up and find the chips limits that way.

Also be cautious w/ your voltage unless you got deep pockets or a good warranty.

hi guys.
just wanted to start off by saying this is one of the best oc guides ive seen around. really clear and detailed. but ive got a couple of questions.
ive been following the guide really closely and started overclocking.
but even at 3.7ghz i seem to be getting bout 70c-73c on realtemp and 1.208v-1.216v on cpuz during the p95 test.
like the guide said i set +0.005v offset and +0.004v turbo. and slowly increased the multiplier. i didnt meddle with the other settings.
idle temps are 29c-32c.

ive some seen posts n screenshots from some of u guys getting 4.5ghz @ 1.208v and 75c.
i know cooling plays a huge part but i think my results are kinda high for just 3.7ghz.
whats wrong? what should i do?

specs are:
asrock z77 extreme4
i5 3570k
hyper 212 evo
8gb ram

please help!

thanks.

what overclock are you trying to achieve? A +0.005 offset / +0.004 turbo is basically a starting point for a 45 multi.

Hi guys.

right now I have my 2500k @ 4.5ghz stable.

My VID is 1.4061~1.3961 and the Core voltage 1.352~1.344 , (using prime95)

I almost left all auto and I only change this settings:

Offset Voltage: -0.20
Turbo Boost Voltage: +0.08

Enhanced Halt State (C1E): Enabled
CPU C3 State Support: Disabled
CPU C6 State Support: Disabled
Package C State Support: Disabled

I don't have too much knowledge in overclocking. I want to know if my voltages are Ok , Another thing is when I try to past 4.5ghz my pc turn off. mad.gif

Thanks A lot!

yes i hope to achieve a 4.5ghz stable system.
okay i got kinda adventurous and i did a -0.005v offset w/ +0.005v turbo.
it brought my temps down a little.
running 4.0ghz i got max temps around 77c and vcore 1.232-1.240.
is it going okay? can i push it somemore?
and what is the downsides (if any) to a negative offset value?

The voltages I run aren't even suicide.. 1.6 on a 24 hour prime probably is safe. 1.65 will just throttle as soon as you hit 93. I definitely wouldn't try a 24 hour on 1.7 though.

Well you might be a little on the high side. My cpu has the same VID but i got 4.5ghz stable w/ 1.32 in bios and 1.296-1.304 in CPU-z. All CPU's are different but i would try a lower offset.

Whats your CPU-z idle vcore?

Just set your multi at 45 w/ a +0.005 offset and a +0.004 turbo then boot into windows. Get your CPU-z idle vcore and then run P95 for a couple minutes and get your CPU-z full load vcore. Post those numbers and we will be able to tell you whether to increase or decrease your voltage

running 4.0ghz i got max temps around 77c and vcore 1.232-1.240.
is it going okay? can i push it somemore?
and what is the downsides (if any) to a negative offset value?

I too have a extreme4 | i5-3570k, CPU cooled with a contac 30 which should be similar or a bit worse than your cooler. Yesterday I got down to do some OC-ing and my numbers were roughly:

4.5 ghz with 1.32 vcore (damn U whea!), 93 max temp on hottest core on prime (85-93-86-87 max temperatures), 22C ambient. Having creep-ed up to near 95 C I took it down a notch to:
4.4 ghz with 1.24 Vcore, 85 max temp on hottest core on prime (79-85-80-79 max temperatures), 22C ambient.
I'm still watching for whea errors on the 4.4 OC, but so far seems fine (slightly disappointed on my CPU oc's, looks like a below average on the silicon lottery)

Your numbers look like the CPU cooling isn't done quite well, and the OC looks similar to the default OC profiles
Cooling: personally I got the cpu cooler blowing air twords the back of the case, from where another 12 cm fan blows it out of the rear. Also I squeazed a 8 cm fan in the front of the case @ cpu level to blow some air twords the cpu
OC: make sure you are not loading the AXTU oc tool with some pre-entered values that override the bios OC.
