Hey guys, just hit 5 Ghz @ 1.44v with my i5-2500k and Asus Sabertooth P67 B3. It was disturbingly easy to get there compared to OCing my old q6600. All I did was set multi to 50, XMP profile for my ram, and upped vcore to 1.44 because i would crash at desktop with a vcore of 1.36. My load temps after 1 hour of Prime95 blend topped out at 53 C with my custom water loop. Should I keep pushing higher? Should I try to hit the highest speed without upping my vcore? Can I hurt my CPU by going higher multi but not pushing the vcore? My temps rock so I figure as long as I dont go crazy on voltage I should theoretically be able to go past 5 Ghz.

Im cooling my i5-2500k with an XSPC 360 rad + 3 Gentle Typhoons in pull, powered by an MPC655 pump running through an EK Supreme HF nickel plated block.

RAM is Corsair Vengeance 2 x 4 GB @ 1.5v 1600mhz, 9 9 9 24 2T

Happy for you but at this voltage it is no feat. Sorry. Personally I do not want see anything above 1.4V. That is why I am using offset so my vcore changes but it is a bit tricky. I would try to lower vcore in your case.

It has a feature in there, something to do with limiting amps and wattage. Its set to 120 amps (I'm assuming there's a missing decimal point), and 300w. I'm wondering if its that amperage limit that's causing my issue, or maybe the fact that I can't lower PLL voltage below 1.8v.
In CPU Power Management, there's the CPU multi box and underneath is about 5 items set to auto, that all deal with turbo. Primary and secondary timings, max wattage, etc. When you click on the one that deals with amperage, you'll know because it will say 'adjust WATTAGE blah blah blah...' in the description on the right. Thank Asus for a decent description

@Kosta88- And yeah, mine hit a wall at 4.8 that seemed disproportionate to the voltage increase. But maybe it's just me. Just seems that I should have had SOME increase with voltage bump. At a certain point, I got none. 1.48 should get you to 5ghz If you're at 4.8/1.45. But I had the exact same problem. See above, it may be your fix.

BIOS, yes, latest. PLL Overvolt enabled too.

What exactly might be my fix - the thing with adjust wattage?

The batch of my 2500k is L042B633

Is this any good?

Can't really tell by batch anymore with sandy bridge, cpus in the same batch can overclock much differently.

I think I'm gonna give up with trying to find a 5Ghz CPU. Just not having any luck whatsoever. I'm on the 6th 2600K (and one 2500K) and none can go past the 5Ghz plateau. All of them can go up to 5Ghz, but that's with high vcore (1.50v+) and that's only half stable.

Here are the 2600Ks I've tried up to date in order:

1. L042B305 (48x - 4.8Ghz - 4.945Ghz)
2. L042B243 (sucks big time, couldn't even do 4.8Ghz)
3. L042B208 (same as no. 1)
4. L050A853 (same as no. 1)
5. L051B138 #1221 (same as no. 1)
6. L051B138 #2229 (same as no. 1) (Current tester)

2500K:

1. L039B120 (same as no. 1 above)

Giving up now. Maybe I will sell the last 2600K as well and retreat to the realm of 2500K and see if it'll bring me a little better luck.
