Can't Overclock to 4.5ghz i5 3570K

[DarkNimbus123]

Hi everyone,
I have a really weird issue going on.
my system:
i5 3570k
h100i
msi mpower
8gb ripjaws @1600mhz
msi hd 7950
fractal r2 midi

I can't seem to reach even 4.4 ghz @1.3V the system just crashes... i dont know what's wrong. it goes through like 2~3 minutes of prime95 and then crashes. I'm probably making a rookie mistake somewhere. I'm just not sure where...

rookie mistake being, dont just pick a number to oc to. start lower, at 4ghz, most of these cpu;s can get to 4 with no voltage increase. go graduallyup from there till it gets unstable. there are other settings besides core voltage that can change how well your cpu overclocks, there are plenty of ivy bridge overclocking guides, i suggest reading some.

actually, I did start lower, i get a stable clock at 4.2ghz but wanted to push it more. 4.3 is also stable. But I don't know what I'm doing wrong after that. 4.4 I can still boot up. 4.5ghz crashes without even booting up at all. Instead of being vague, can you maybe link me to these guides or at least give me some idea as to what i could be doing wrong..

ok so you are stable at 4.2, not 4.3, so if you can not get 4.3 stable with voltage increase, you will need to look at something else.
http://www.overclock.net/t/1247413/ivy-bridge-overclocking-guide-with-ln2-guide-at-the-end
that guide shows you a few things like load line calibration which will stop voltage drop under load, it may be all you need. Keep an eye on your temps, even water coolers aren't magic with these cpu's due to the crap thermal paste between the heat spreader and cpu die.

plenty of google links.

let the cvid adjust your voltage for you automatically and get your load voltage stable first with line load calibration.

ok i tried this but it bsod'd 🙁 whats wrong with it?

 

[nikoli707]

i suspect that under load your voltage is dropping lower than what is set in the bios(manual or auto) and your chip cannot sustain its high clock without the proper current. LLC and/or a combination of voltage offset can help this. you should use hwmonitor to see your min/max vcore voltage and get an idea of how far up or down the voltage is adjusting compared to the static number than is in the bios. just keep an eye on temps if you start messing around.

update your motherboard bios to the latest available. dont use auto settings, set your cpu voltage to whatever it was when you had it stable at 4.2, and just tweak the llc for now, and see if you can get past 4.2. if not then llc isnt the issue.

i did what you said still bsod. if llc isnt the problem what could it be?

Not all CPU's have great overclocking ability. It's a lottery.

I know that but shouldn't a 3570k be able to hit 4.5 no problem?

have a read of that, they seem to need to put a fair whack of voltage in to get desired results. maybe that is all you need.

 

[Dark Lord of Tech]

No it's not common due to the needed high voltage.

1.30v at 4.5ghz is probably too much voltage drop down to about 1.10v fixed voltage and start booting from there, each failed boot to the desktop, bump the voltage up one increment and reboot, continue this until you successfully boot to the desktop.

From that point run IBT (Intel Burn Test), on standard setting, each crash continue to bump the voltage up one increment, until you can successfully complete IBT.

Then run some type of benchmark program to bring the graphic load into the picture, and as before a crash requires another voltage bump up, until you reach 100% stability.

Creeping up to a stable clock means you won't be running any more voltage than needed.

Note: Manually BIOS set your memory speed, timings, and run a 2T or 2N command rate, and your DDR3 slot voltage to 1.50v.

I managed to get a stable overclock of 4.4 at 1.285V... 1.28 and it bsod'd. that seems too high... i tried everything you guys have suggested. did i just get a really horrible chip or something?

 

[nikoli707]

ivy bridge and haswell are not sandy bridge. while legendary sandy bridge chips almost always go to 4.8ghz, about 90%, ivy and haswell average about .3ghz behind as far as the 90th percentile. in reality all sandy bridge chips will hit 5.0ghz, you just need massive voltage and a good motherboard capable of feeding clean strong amperage and voltage to do it. ivy and haswell probably can all hit 4.8ghz, but factor in high heat output which requires water cooling and then also a great motherboard and lots of voltage with the right combination of settings.

if you read the link i posted before a review site said they had to bump the voltage more than normal. so could be combination of cpu and motherboard.

Yeah that might be why. I'll play with it later on and see. But for now ill stick with this ridiculousness since I'm getting max 85 degrees in the burn test and 77 in prime95. after some new fans ill tweak it around and try again. Thank you all for the help, much appreciated.
