will try to lap that CPU even more when I get my hands on some 2000 grit paper again..

And and Crosshair V formula, that's pretty dandy lol
If you could try to monitor your temps that would be nice, so if I see you get a nice bump it will motivate me to do mine like a mirror even more lol (and flatten it.. i guess it need to do for that anyway..)

Nice Strong. I'm running IBT now with new MB and old settings at 4.7GHz and bumping voltage down each time it passes and so far it's passing. Have you tried bumping vcore down a notch at 4.6?

Here's how I did my lapping (Click to show)
biggrin.gif

Set-Up

Acrylic Panel for a smooth surface
Masking Tape for locking in the papers
CPU Blister foil to protect your pins from being bent
Sand Paper Grits:
100 - to flatten the IHS
150 - to smooth up the 100 Grit marks
400 - Starting to make finer marks
600 - Almost there
1000 - By this point, the marks should be visible but not deep to the touch.
Polishing Cream (not shown) - to seal the deal
Angular Brackets - to guide your strokes for a linear finish. optional



My method, (optional)
The bracket is used as a guide for my strokes to be consistently linear.
Pressing the protective blister foil to the bracket while scrubbing the CPU to the sandpaper



Start off by leveling:



That huge lump in the center needs to be leveled to the raised edges:



Continue till you get rid of the lumps:



Once you get to a point where things look evened, give it a few checks and a few more shoves while twisting the CPU after a few strokes.



Then proceed to the next grit after clearing the marks of the previous grits.

After 100, I proceed to 150 to get this finish.



A few strokes of 400 to check:


A note: Stop and proceed to the next grit if all you can see are the marks of the current paper.! (Click to show)
A note: Stop and proceed to the next grit if all you can see are the marks of the current paper.





After 600 Grit: reflection starts to grow:





1000:




You can go for higher grits after 1000. I didn't. It only leaves marks that never end.

So I took out a Polishing Cream: anything will do.

Put some to the paper. and some 30 minutes or trying to figure out the pressure and amount of strokes needed to produce a good finish, I felt satisfied with this:



Looks off? biggrin.gif low light:


Only on close up. And can no longer removed the those lines.

But, I'm done. This is already awesome.

Ok Mus for the final you need this. http://www.woodturningz.com/Plastic-Finishing-Kit These are foam sanding pads and will polish anything you can put in front of them. Don't let the "plastic throw you off". I've used these on brass bullets before.

Thanks for the tip.

I don't think I would for the CPU though. The finish will not make difference in temps. And I won't see it once installed.

I could've done it better with a few strokes on leather actually.

But I might. For other things. I still need to polish my pump top. So again, thanks. smile.gif

So what are you doing to your chip? Is it just that you have very low spots on it? It looks that way. Someone here shined his chip up like a mirror so I figured more of you all were into this.

I have a couple of chips. An 8320 and an 8320E.

My 8320 is a pig. Requires a Vcore of 1.600 Volts to stabilize 4.8 GHz! Temps lie in the high 60s C.

The 8320E on the other hand, requires 1.5 for 4.9 GHz. But here's the catch. It heats up past 70C at that voltage.
Warning: Spoiler! (Click to show)



It doesn't make sense. So I thought, what the heck!

After lapping the chip, I was able to get past 1.55. With a much balanced heat production.

I see the temperature issue but the voltage for 8320 at 4.9GHz is 1.50. Seems like a pretty good 8320 to me. Of course I have no idea what you are using for cooling. I'm fairly new at overclocking but not computer building.

Better than my previous one. For sure.

But nothing so special.

I have a 480 and a 360 for the rads. But ambient temp right here goes as high as 35C. Hopefully rainy season gets here soon. biggrin.gif

Hows the ambients been treating you so far Mus?

Left mine running Prime Small FFT's for about 5 hours last night and got a max temp of 48c with 1.5v

Dang Mus are you on the equator? Do you run an air conditioner? It gets hot here in the summer too but I keep it cool in the house. I'm running a 240 rad and 8 fans. How about a fan behind your MB? Have you got that one too?
