Hi guys,

I'm trying to OC my 3570k to around 4.5 Ghz since this seems to widely be seen as what all chips can do. I've tried both with fixed voltage and with variable but cannot get it to launch windows at 4.5 Ghz. The highest I've got it working at is 4.3 Ghz using variable cpu voltage but this is currently using a voltage of around 1.38V at full load. Using fixed voltage I previously couldn't get it stable below 1.35V. At these settings the temperature hits 90°C in 20 or so minutes of prime95. I've listed my setup and what I believe to be the relevant BIOS settings below.

If someone could tell me if i've made any mistakes in the bios that would be great. Also what are the odds that this is the limit of this chip?

Processor: i5-3570K
MB - Asus P8Z77-V pro
Ram - 2x4gb corsair vengeance
cpu cooler : Antec H20 620
SSD - Kingston HyperX 120GB
PSU - Corsair Builder CSM 600W Modular
HD - 2x 3tb 7200 Sata
GPU - Sapphire 2GB HD 7850
3x case fan

BCLK Frequency - 100
Turbo Ratio (all cores) - 43
CPU Voltage - OffsetMode
CPU Offset Voltage - (-ve) 0.010
CPU PLL Voltage - 1.8

Cheers for the help guys.

Cheers, I've reposted in 8pack. I did stop it when I saw it was over 80c but will be paying more attention to temps in the future.
 
Hi Stuie,

Cheers for the help

Using stable voltage I previously got to 4.3Ghz at 1.35V and didn't want to go any higher due to heat.

Using the settings stuie suggested and only the multiplier I got the following results

@4.4Ghz - BSOD pre windows
@4.3Ghz - Running Prime temps reached 85°C in 2 minutes so I stopped the test
@4.2Ghz - Prime temps were 81,88,83,83 after 1 hour Vcore 1.376V,
 
Ok, I reset the MB to stock. Prime has been running for 10 mins. Vcore is mostly around 1.264V but has got as high as 1.28V. Max temp is 64°C. I'll keep it running but nothing looks like it's going to change.

Edit: after 1 hour of prime 1 core at 70, other three at 66 Vcore still 1.264

Cheers for the help Stuie, good to know where I stand.

I've continued playing and think I may be able to get it stable at 4.5GHz with about 1.5v supplied. Is it the volts that are going to kill it or the heat generated by them?

If the latter I think I'll run it at 4.3Ghz for a while until I've got enough cash to buy a i7-3770k if required then lid the i5 and see how well I can do with improved cooling/buy a 3770k if I break it.

As an added thought is there a chance I'm overloading the PSU forcing it to supply poor quality power which is causing the issue?
