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.

If it just about stable at 1.38v and 4.3ghz then you have a seriously poor clocking cpu, hard to believe its that bad though as with my 2500k I can do 4.7 with 1.38v

90c under testing is appaling! The ivy runs hot because of the thermal paste use under the cpu ihs. try to keep under 80!

I would ask 8pack in his section tbh.
 
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.
 
I would check your advanced power settings m8, ya prolly need to turn up your LLC it will help keep thing stable at lower volts. Im guessing thats why your needing so much voltage to keep it stable, maybe ya just have a dog of a cpu.
 
negative offset is fine for up to 4.3 ish however you will need to add voltage for anything above that. When you tried with fixed voltage what did you try up to?

For 4.5gz id start with just adjusting

CPU Offset + .050
PLL voltage 1.65
LLC High

Give that a go and report back to us regarding loaded coretemp reading and cpu-z vcore readings
 
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,
 
Going back a step then can you reset back to stock settings and post your vcore, I know the 35XX arnt that good clocking compared to 37XX but im just really surprised its this bad my 3770k does 4.5 at 1.23v which under most load like folding and priming is actually 1.208 vcore

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

wow, unfortunately I think youve got a bad clocker I keep seeing more and more of this among the 3570s needing higher volts just for stock keep plugging away at it but i think your going to struggle to break 4.3
 
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?
 
1.5v on ivy imo is not 24/7 safe, and I wouldn't want to be putting those sort of volts through one for too long.

I dont think its your PSU I suspect its just down to having a bad clocking cpu there seems to be more and more 35's that arnt great clockers and require lots of volts just for stock if your starting off in a bad place your never going to finish well. Run it at what you feel comfortable doing and maybe eventually swap it out

+1

please don't go above 1.4v for 24/7 use
 
mine is doing ok, i have this system:

i5 3570k
giga Z77x UD5H
16 gig of hyper x 1600 ram
antec 620

i increased my x to 45 only, no other settings and it's running stable 24/7 at 4.5 ghz. avg temps are 30C

not sure if i could ramp mine up more but scared too :)
 
Sounds like you got a better chip than Standex, ide run CPUz under load though just to check what voltage its giving ya. It automatically adjusts the voltage, i remember reading a thread where a guy had done the same and was getting over 1.4v going to the CPU.
