[Help] i5 3570k won't go above 4.5MHz?

post #1 of 48
Thread Starter 
Hey guys,

I'm pretty new at overclocking but I've read some tutorials and forums threads and I decided to try overclocking my cpu. But firstly, here are my specs:

i5 3570K (CoolerMaster 412S)
ASUS Z77-V
G.Skill RipJawX 1600 CL9
Sapphire 7970 OC 3GB
Seasonic X 850Watts
NZXT Phantom 410

So I've played around with the AI Suite II and also the BIOS a little and somehow I just can't manage to get it over 4.5MHz. I'm currently running prime95 on 4.5MHz (43 x 104.7) with 1.275v BIOS (1.312v+/- CPU-Z) for about 8 hours in with no problems. Before this I tried 4.5MHz at 42 x 107.1 with 1.250v BIOS and it crashed after about 1.5hour+ of prime95. I tried running 4.6MHz at different levels and it always crashed. Sometimes it wouldn't even boot up to the log-in screen and crashing at load up. Also, although I'm running stable at 4.5MHz right now, I've noticed that the ASUS software is sensing my motherboard's temperature at 0.0degrees. Could it be a bug? Maybe I'll restart after 10 hours of prime95 and check again.

Oh yeah, I've also realized that increasing BCLK frequency also increases DRAM. Does this mean that I'm overclocking my RAM together with the CPU?

Anyway, do you guys know what I'm doing wrong? I just can't get it any higher. And temperature isn't an issue. My cpu is at 59-61C after 8 hours of prime. Even further before this, I tested 4.5MHz at 42 x 107.1 with my voltage on offset auto, temps would hit 63-69C but mostly around 66ish while the voltage runs around 1.350+/-. I'm kinda at a loss of what to do now. Any suggestions?


Cheers cheers.gif

Right,

Your first mistake is you didn't read any guides on how to overclock your processor. Your even bigger mistake is trying to overclock your BCLK which shouldn't be touched since it's linked with your PCI-E lanes and other parts of your machine

Put that back to 100, don't touch it, set your multiplier to 45 and increase your Vcore to around 1.3v

Don't change your BCLK again

Hey thanks for the response. Hmm so that means I won't be able to OC my rams? What else does BCLK affect? And why is it so bad to overclock BCLK? Sorry if it's a stupid question :/

Also, isn't 1.3v a little high for 4.5MHz? I mean, I read that the ideal for 4.5MHz would be 1.250v that's why I'm trying to keep it lower. tiredsmiley.gif

Mine takes 1.310 for 4.5 and 1.496 for 4.7.......
Atm im at 4.6 with 1.4v 24-7 temps dont go over 70c ever think highest i seen was 68

And you oc your ram with the divider ie 1600/1866 ect and the timings and ram voltage

For starters, its Ghz, id be a little concerned if your Ivy Bridge CPU was running at 4.5Mhz wink.gif

BCLK affects CPU speed, RAM speed, PCI-E lane speed, and SATA Bus speed, so when you up it you are effectively Overclocking your PCI-E bus and SATA bus too. This may seem good, but they need to be almost always left at their default speeds.

As for voltage, every chip is different, you've got to play around. As you seem quite new to Overclocking etc, id advise you to read a few guides on here to get you started smile.gif

I can't seem to find the ram slider on my asus bios :/ Also, which mode mode of prime95 should I be using? Small FFTs, In-place large FFTs or Blend? I've been using mainly the large FFTs to test so far with some time on small FFTs.

OOPS. Hahaha crap. I was looking at 4500MHz on CPU-Z when I wrote that and forgot to convert! tonguesmiley.gif

Okay I'll be playing around some more then smile.gif Do you have any good guides to recommend? rolleyessmileyanim.gif
