At least two of the processors we tested required 1.44Vcore for 4.5ghz. The temperature rapidly rises as soon as you hit over 1.4V. At 1.4V, it is still very manageable but you can only clock it at 4.3ghz

4.5GHz @ 1.3V +- 0.05V is possible to pass at least 2 hours or more of Prime95. Don't take it as a 100% guarantee as different chips in different batches will demand different amount of volts to be stable. 4.5Ghz is a good range as the volts needed for 4.6GHz or more is going to be a lot, temps increase a lot as well.

Ive tried 4.5ghz at 1.38v just now.. And after bout 45min running on prime95 the max temp was 91c. Pretty high isit. So scared.

ok. Will try ur setup after dis. Hehe


P/s: me just using h50 push pull

91C is too high, or at least too high by my standards. 1.3V should be a sweet spot, anything less you'll risk some stability. H50 isn't enough. You should get something like a H100 or air coolers like the Noctua NH-D14 or similar.

3770k at original setting @ WC set

Fresh windows just download diabo3 nia... lol

The voltage
What your WC setup? Will be glad if you OC it to 4.5Ghz and share the temp

very stupid wc setup. hahaha

use last time corsair coolwater but modify to new lga 1155 block nia.

i5 3570k @ 4.8ghz, on Air Stressing

Send us a box of it (5 units), don't want EE edition. There's already a line up in our system.

Ok thanks bro... Later ill use the noctua one. Still waiting for it, coz my fren wan to upgrade to wc.. Hehe

hi, i have the i5 3570k, and also M5G mobo, but im using Corsair Vengeance high profile, currently still using stock CPU cooler fan.

the first time I boot into the windows, i got BSOD, after number of attempts and finally found out the problem is Turbo Mode, initially it was set to ON by default and technician didn't do the right BIOS setting for me. It was in vcore 1.33v with stock speed. I just updated my BIOS, now everything is set to Auto, using the Turbo Mode clocked @3.8Ghz. Is it safe to put all in Auto? I do not much about the vcore, so I let it be Auto.
Which shop in lowyat I buy Prolimatech Genesis CPU cooler fan? Is it possible for me to install Noctua NH-D14 or Noctua NH-C14 ?

maybe you got a bad 3570K which loves voltage so much so i suspect the BSOD (please check post #1) is due to insufficient vCore when the turbo clock kicks in your CPU needed more voltage. my stock clocked 3570K on M5G is pretty smooth with the default settings & latest bios.

Turbo frequency for 3570K is up to 3.8GHz & one core only. Turbo can be overridden by setting the multiplier manually.
CPU level up is a feature offered by Asus boards for auto OC sometimes is not as reliable as desired. Manual OC is always the best although more work to do than just let bios OC for you.

Added on April 23, 2012, 11:04 pmvery nice bro, now toast it with LinX & see.
I don't think this 3770K will survive on my RASA kit.

Haha... But the stupid asus p8p67 cant unlock the core la...



Cyntrix:- sure 5 unit? Lol

Peanuts. You don't want to know how many 3570K we have here

Is there any BIG different for 16+8(Asrock fatality z77) and 8+4(Asrock Extreme 4 z77)? Both can OC perfectly right.

More power phases do not guarantee better performance and does not mean better OC. Generally, more phases should make for smoother voltage output, but it is only one of several factors in the design of the CPU voltage regulator. Power phasing is more of an energy management feature than an OC feature. It will really only feed the CPU with as much energy as it needs, and the other power phases get turned off. The Fatality PROFESSIONAL is usually ASRock's flagship mobo and this is the model you should get.

Any good recommendation of CPU air cooler for mobo M5G and high profile vengeance ram ?? I'm thinking of these Prolimatech Genesis, Noctua NH-D14 and Noctua NH-C14 ? For the Noctua, some said can't fit, some said can fit. Which 1 is the best among of the 3 above?

M5G + Noctua NH-D14
