Things needed:
Flat surface - e.g. a mirror or a piece of glass
Some type of tape to hold the sandpaper in place
Sandpaper - people say not to use anything grittier than 400 grain.. i started out with 200 which is contrary.. And actually I ended with 200.


Tape down the ends of the sandpaper to the flat surface. Grab the thermal conductor. Try to hold it as flat as possible while swiping it on the paper to avoid making uneven edges. Make straight line swipes back n forth on the paper. Rotate the conductor 90* or 1/4. Proceed to run the conductor across the paper. Keep doing this until you've done all sides.

BEFORE you do this take a look at the bottom of the heat-sink and see if it looks to have a bow or is con-caved. I was surprised to find one on mine but it was a relief because it explained my 45*c core reading while my 970 was idle.

Lapping the CPU, and HS will void their warranty.

Ah, this sounds a fair bit risky. I'm going to try applying a better quality paste first, in a smaller quantity, and see what happens first.

Yes, it absolutely is. Try Arctic MX4 or even Indigo Xtreme before you resort to lapping your cpu.

On the other hand, you could try lapping your heatsink - a lot of people have luck with that and it doesn't stand to do the damage that lapping your cpu can.

Unless you're maxing out your current system and actually need the extra performance that the 4930k will give you, I would say don't do it.

Although the 4930k performs 250% better (according to CPU Bench), it will cost you alot and it might not be worth it. Especially since you'll just be doing gaming, you probably won't see a big improvement, or any at all.

That 930 should easily clock to 4.2+Ghz so i'd wait

Your other option is the Xeon L5639 1366 socket chip. I bought one for my Asrock X58 Xtreme main system. The Xeon is a 32nm 6c 12t 60w chip designed for dual CPU workstations. The best part is they are going for ~ 85$ on eBay. The only caveat is that you have to make sure your motherboard will support it first, and it's low multiplier. My EVGA 760 A1 Rev 1.0 board will NOT accept it without a simple mod. You have to short out 2 points.. I've seen pics floating around of how to do it but I opted for a higher multi (24x for the 970) The Xeon runs @ 2.13Ghz stock. 3.2Ghz is obtainable with high BCLK I've seen some guys over on Anandtech pushing 3.56Ghz on all 6 cores. It will Turbo. But not on all 6 cores. IIRC I think I've seen some turbo up to 4.4Ghz. And that's an 85$ Chip!!!

Thats what i did as well and seemed to work ok in my mobo. Hexacore for $85 was a no brainer for me and love the boost in speed!

Problem is that with such a low multi you'll max your board out before even hitting 4ghz.

Yeah, looks like the only boards able to get to 4gjz+ are the sabertooth boards.

Seeing about a 30% increase on my 4960X over my 980X so far, haven't OC'd it yet. Most of our guys are hitting 4.5-5.2 on their chips thus far and w/ the latest bios update looks like they're pushing a bit more w/ better settings. Going to test with 4.5 Tonight and see how that goes then attempt 5.

Just because the clock speeds are similiar doesn't mean they operate the same efficiency, it seems that IB-E is more efficient at the same vs the 980, so there's a definite improvement. Though should you upgrade is up to whatever you're doing. I like multiples of 2 and 4 vs 3 hence jumping off x58. x58 was a great series though.

Thats real interesting Luna!

I was curious myself since I got the "itch" still, but it's hard to justify a whole new upgrade when most things run fine. Right now I am debating opening that third titan and installing it. I look at my benchmarks and say HMMMMMM
