So I got my 3570k today

[Lauralarry]

I can't run 4.7 stable with the H100 but 4.6 works really well hmm.

this is my first overclock idk what I'm doing but this is soooo much faster than my Pentium D 3.4ghz lmao..

 

[Josh Weston]

That's a fair bit of volts for a 24/7 clock, even with the H100. What are your temps using Prime/Intel Burn Test?

It's hot but doesn't go above 90c on prime 95, what voltage should i use for 4.6 ghz? it's only been on for 10 hrs maybe.. i think I'll check the temps since the paste is burned in

 

[VengeanceUK]

maybe you struck out on the silicon lottery like i did, i settled for 4.4 in the end

 

[Josh Weston]

For Prime, 80 degrees is usually the cut off point. Just try getting your volts down until you get instability - i'm running 4.5GHz at 1.21 volts, and JamesRiley94 is using even less. Just work it down.
Use Intel Burn Test and try and last 10 runs on Maximum. Monitor the temps - you don't want them going above 86*C or so (IBT is tougher than Prime).

is this better? or do i need to go lower? and how long do i run prime 95 and under what setting?

 

[Josh Weston]

Just keep taking down the voltages step by step at, say, 0.01v at a time.
Every time you bring the voltages down, either let Intel Burn Test (preferred) go through 10 runs, or run Prime for half an hour to check if it's stable. If it is, take down the voltages another step. If not, bump it up by 0.005v until it becomes stable once more. Then, you'll find the limit to your overclock.

Can I go higher?

 

[computergeek]

Yeah you should be able to and try giving the FSB or VTT FSB some volts as well as your ram and maybe SB if needed?
But really just up the vcore a bit more and if you're not satisfied with the vcore being so high tweak the above voltage like I mentioned believe me it helps although, I don't have my ivy bridge system just yet.
That is quite some months off but a rule of thumb I follow for the VTT or VTT FSB voltage as it depends on your motherboard and bios it is running?
In terms of what this will be under, just bump the voltage up one on the VTT or VTT FSB voltage and no more then a maximum of 1.3.

 

[Josh Weston]

^Yeah, that doesn't really come into play on Z77, dude. Just vcore and the multiplier, that's all you need to worry about.

Only you can say for sure, dude.
You know the temperature limits, and you'll know if it's stable or not.
It's up to you now

 

[computergeek]

Also have you bothered to alter the DRAM timings?
Just wonder as auto isn't always best when going for or achieving higher CPU overclocks.

 

[Lauralarry]

i think I'm satisfied with 1.24 @ 4.5

No I've been trying to get 4.7ghz with 1866mhz ram with timings of 9-10-9-27 1.5v

The memory controller on Z77 is VERY solid. You really don't need to worry about messing with timings unless you're going for some stupid overclock.

Check my sig - I reached 5GHz and my RAM was running at 2133MHz no issue. It wasn't stable, but with a big ol'water loop it could have been.

If I were you, I'd continue to try and get the volts down if you can. It's not like the CPU will perform slower with less volts, it just means that it will use less energy and won't create as much heat - win win.

 

[computergeek]

My mistake didn't realize that with the Z77 motherboards that it wasn't necessary, hmm well someone may have to correct me on this as I do not own a newer CPU but go for 1.4 or 1.45 on the vcore but just watch your temps.
Oh lmao you have a h100 water cooling kit so temps shouldn't really be an issue.
And yeah lol I like to go for nuts overclocks lol.><

My man, I fear you've been out of the loop for too long.
Ivy runs hot as soon as you pass anything more than 1.2 volts through it. 1.4 would DESTROY his CPU as the H100 just wouldn't be able to cope.
4.5GHz at the low end of 1.2v is just fine - anything more and it shall create unnecessary heat.
The new, and relatively unrefined 22nm manufacturing process of the Ivy Bridge CPUs just can't cope with that many volts. Hopefully Haswell shall give us better results, temp wise.

 

[computergeek]

Lol CPU's get smaller nm wise and now we cant throw lots of volts through them.
And yeah I have lol, I took a year off and only came back to the scene recently.
Hmm well I did a google search and some have managed just below 1.4v but they probably have a better water cooling setup.
Well I might go with sandy bridge instead as I like my voltage when overclocking then when, I finally finish my PC upgrade later this year.
Plus cheaper parts lol.

 

[Lauralarry]

just gonna stop overclocking I'm fine with crappy 4.5ghz, I haven't played one game since i got this cpu, I been on a pentium D 3.4ghz for 5 years.. Really just don't care lol. and I hope to upgrade to skywalker or w/e is after haswell lol I plan on having ivy a bit longer

Well, as long as it's all stable and your temps are fine, it's a success story, no?
The performance gain from 4.7GHz is incredibly marginal, anyway.

You really would need a custom water cooling loop to run these chips over 1.3v 24/7 (basing this on my experience, at least).
And yeah, to be honest, a 2500k at 5GHz performs at around the same level as a 3570k at 4.5GHz, so there really is little difference. If overclocking is your thing, then SB is the way for you

 

[computergeek]

I hear you mate it does suck being behind with the times only to upgrade and find you have to relearn overclocking all over again.
But happy gaming and on that note I will reinstall Need For Speed Underground 2 and get some serious graphical modding on it again.
Also please may I have a link to your wallpaper, thanks.
Also CBP is right only someone like me with OCD would be that obsessed with getting every single mhz out of a CPU.><
And yeah CBP you're right again sandy bridge for me but I will probably get a motherboard that supports both sandy and ivy bridge even if having a sandy bridge CPU in a motherboard that supports both may not be ideal.
