How far can i push sandy bridge?

[Perbox]

I've got an i7-2700k that I pushed to a solid 5.2ghz overclock with 2 dual 140mm rads and solid hardline cooling. my question is, how far do you guys think I could push this before it completely destroys my water cooling setup.

I would be more worried about the voltage destroying your chip... rather than your loop.

4.2 I meant 4.2 GHz

[GDRRiley]

what voltage. you can push it pretty far 

[Perbox]

its running at 1.35v

It's been a while but I think my 2700k hit 4.8GHz @ 1.425v and I probably wouldn't recommend going higher than that voltage as a max. Watch your temps. Take it slow.

depends how much life you want to get out of it.

 

if you only want to keep it for another year before upgrading, then push voltage to 1.4V or more and go for it.

if you want it to last a long time, and don't plan on upgrading anytime soon, then maybe up voltage a bit more, but nothing crazy.

Well, there's actually a good, if time consuming, way to know how far you can push a CPU or any piece of silicon. I found it in a pretty old but still relevant overclocking and overvolting guide over at overclockers.com

oh that looks sweet, I'll be sure to read it!

Try 5 or 5.1 @ 1.5v. Sandy can handle more voltage than newer chips.

I have my 2700K running at 4.9Ghz at 1.45v. I have a H105 AIO cooler though with delta fans strapped to it. CPU doesn't get past 64C, but my hearing sure takes a hit. In normal use though, it never gets that hot / the fans never ramp up beyond 30-40%. I was running Intel Burn Test (20 runs) to get the overclock stable.

 

I do want to get 5.0Ghz some day though...but I'm afraid of crossing over 1.45v.

 

But yeah, I originally had a 2500K (4.6GHz) but I wanted a bit more punch for my usual day to day workload, so I picked up a used 2700K for $130. I was too cheap to upgrade to kaby lake (Need new ram, etc). There was a pretty notable performance gain for me going to the 2700K.

for sure! the 2700k i just overclocked to the same settings that you posted about. seems to be working great. going to run more stress tests though.

4.2 at 1.325 is kinda high (4.5 was that voltage norm). with 1.45 being the top voltage before the temperatures blast off. either the CPU has degraded already or the chip is not a lottery winner. new purchases the 2600k/2700k could roll 4.7/4.8 at 1.45 volts under 85° (25° ambient) 100% loaded.

you can push it all the way to the wall, once you hit the wall you cant get over it.

yeah, for me, I usually just run 20 passes of Intel Burn Test at maximum and call it a day. I have yet to see a PC that's unstable after surviving this. I think mine took 4 hours if I remember right to survive.

 

Happy you managed to find a good overclock. Was your overclock similar to mine? or did you have to add more voltage?
