Hi OC sifus,
I just bought a new costa rica chip 3570k..dunno whether this is good but that's what I think so far. this chip so far stable at:
4.5GHz @ 1.165v
4.6GHz @ 1.225v
and now I'm running at 4.8GHz and still testing. Vcore at 1.335v set in BIOS so far no stability issue(super pi/crysis 3/3dmark11) but later tonight will run LinX and P95.
any 3570k owner care to share their OC and vcore please? sorry I'm not going to read previous pages cause its too much 100++ pages

.
anyhow this 3570k is definitely better than my previous 3770k which needs ~ 1.41v at 4.8GHz. here's a screenshot after finishing Super Pi check:
update: 5.0GHz for this cpu needs 1.45v to be able to bootup to windows..gonna try crysis3 later see if it can hold up or not,
wongtheboy proc is even better than this but nonetheless this 3570k is still better than prev 3770k in terms of oc

Nice chip bro. You should be able to run 5.0 for 24/7 if you decided to delid it.

Greetings to all the experts on this thread.
I've been stress testing my 3770K @ 4.4Ghz using the custom prime95 test for 6+ hours, and it appears to be stable thus far.
I'm concerned that I've got a 'bad' chip though. Is my chip is running unusually hot for a modest 500Mhz overclock?
Screenshot:
BIOS settings, misc details:
» Click to show Spoiler - click again to hide... «
Internal PLL overvolt - Disabled
Vdroop - 100%
Digital Compensation - High
Core OCP Expander - Enhanced
Overspeed Protection - Disabled
1,2,3,4 core Turbo limits set to 45x
XMP profile enabled (default: 1866Mhz, 10-11-11-30)
CPU Vcore left at AUTO, EIST unchanged (enabled)
High performance mode enabled in Windows 8
No air-conditioning (thus far), ambient temps estimated ~27-28C
CPU cooler: Hyper 212 Evo with one custom sickleflow LED fan
TIM: Arctic MX4
Assuming Prime95 runs fine for at least another 6 hours, would the above settings be reasonably safe for long term use?
Your temps looks normal for an overclocked Ivy, even though it is just a moderate OC.
Once the stability test passed for long hours, the OC should be fine for 24/7.
Instead of auto vCore, I'd set manually @ ~ 1.184v. Auto means you let mobo BIOS decides for you. Try lower vCore, if possible.
