i5-2500K/2600K batch number and o/c results

[OC Nub]

ok so 56X would be the max multi on this chip?

yeah I actually took a picture of it with my camera, its says 6.4ghz and all my other options stuck as well

Its weird that your chip will boot to bios at 64x. Its hard to say if 56x is the max but Id say yes. Try dropping bclk to say 99 and see if it boots, or raise bclk t
o 102 with 55x multi.

One chip I use has a max multi x56 normally, but it has booted at x57 when I was able to get it cold enough on water. It runs best though with x54 and bclk at 104. The chip has a strong IMC, it passes 32m at 108.7 bclk. The other x56 chip i use runs best using the x56 multi, and runs the same max mhz with HT enabled, just needs a little more vcore to use HT, but passes WPrime and 3DM06 CPU test no problem.

They all act different, its best to try different multipliers and find the sweet spot for your chip IMO. Some will run higher mhz using a lower multi, some wont do high bclk and run best with the max bootable multi, Im guessing this is IMC related but its just a guess.

Another chip I had (but killed) was a x57 that I was able to boot at x58 when dropping bclk to 98-99. I was hoping to get it to run x58 for benching with dryice, but its been hot and humid, and I think condensation killed it doing my first dryice run.

Is there settings that need special attention to get the benefit of cold? I have had three 54x cpu's that all dropped in multiplier when I tried my SS.

From the EVGA Claassy thread somebody went to a 1500W PSU and beat the cold boot problem with a 970. Is that a good route to go (COST is )

(Got two "better" chips now tho....I hope)

Ask Dumo, he runs SS, but I think he had a chip that had a cold bug above +0c. Dont think there is a setting that will help with cold bug.

Raising system agent voltage will help some when maxing out the chip and meory, I hadnt tried it but Dumo suggested it and it did help on P67. On this Z68 though it runs at default just fine.
