2500k @ 5GHz?

I doubt it. I have it on an H60 and my load temps are very high under only 0.005 offset voltage @ 4.4GHz on my i5 2500k.

Since you have an H60, your temps are going to rely heavily on your ambient temps.

I would not consider gaming temps good measurements of OC stability or potential. You need to run a benchmark which fully stresses all your cores. If you're getting less than 50*C across all cores @ 4.4GHz I'd say you have a golden CPU there and you should have no problems getting to 5GHz. But that's a pretty big if.

No way... unless its a golden chip.

I ran 4.4 all day on an H50 that I had to replace with an H60 recently. 5.0 is up there.

I personally got my friends 2600k to 5GHz on air. That's why I was so confused with my lack of OC. Is 4.7-4.8GHz doable?

Silicon lottery, some chips are better than others. I have a friend whose 2500K wouldn't go past 4.3GHz without really crazy voltage, while I'm able to take my Ivy up to 4.8.

I dunno what's more odd... The SB stuck @ 4.3 or your Ivy being capable of 4.8 D:

I don't doubt that, it's not an UNREASONABLE OC, it just isn't that common either.

Results are representative of 100 D2 CPUs that were binned and tested for stability under load; these results will most likely represent retail CPUs.
1. Approximately 50% of CPUs can go up to 4.4~4.5 GHz
2. Approximately 40% of CPUs can go up to 4.6~4.7 GHz
3. Approximately 10% of CPUs can go up to 4.8~5 GHz (50+ multipliers are about 2% of this group)

So I guess I should be asking about getting up to 4.7GHz?

You should be trying, not asking. There is a chance that it will work and there is a chance that it will not work. Only way to find out is to try it since every chip is different in terms of voltage/multiplier settings and potential. You seem to be on a good path, continue with small increments, monitor your temps and stability and see where it takes you.

You should be happy at 4.4GHz. That's a 1.1GHz overclock. Why risk frying your i5 2500K just for a 2-3% performance boost at 5GHz in games. I'm at 4.5GHz using 1.35v and I'm more than happy with this. You should be, too. Your GPU(s) are the thing that really matters.

No one can tell you what you can get. There is literally no point in asking. The only way to find out is to see how well your chip overclocks with the cooling you have and the motherboard you have. We can't account for those variables

Welcome to YMMV life... lol. It is all luck of the draw. Just go for it and see where you end up.

Asking was trying to suggest some settings you guys recommend as I've already tried getting stable at 4.6GHz and had no luck.

Socket 1155 is a bit simpler to overclock than 1150. Vcore is pretty much the only value with a huge impact on maximum overclock, though some are able to get a higher stable overclock by enabling "internal PLL overvoltage" or iPLL. Others have luck loosening memory settings up a bit, e.g. not enabling XMP, setting 2T command rate and maybe bumping up timings a hair. In my case, the only setting that makes any difference is vcore though.

You're dreaming of hitting 5.0 on that thing especially that little cooler, IMHO.

Been fighting with the newly bought X5650 to get it stable at 4.4 myself on air, and it's looking pretty good.

You might get a little more I imagine but .............

well you said you got your "friend's" 2600k to 5.0 so it sounds like you would not need any help. :p
