Yeah, seen that.
That's more like it wink.gif grats!

The only place I have found 2000-3000 grit sandpaper is eBay, I still have some from years ago. The best surface for lapping is tempered glass is as flat as it gets! At this high grit sandpaper it lasts a long time, there's a specialty hardware store near me that sells everything and non of the stuff is available anywhere on the planet! They even have allen head bolts that are as wide as a pie and weigh over 100 pounds, probably use for something larger that a street light post.

Consider that most don't have the balls to lap a processor you are adding to the value and greatly decrease the amount of TIM needed, this give the user a better chance at a great successful mount!

Hey folks! About to take the plunge...got a couple questions though:

1) Liquid Ultra should not be used on aluminum surfaces, right? What's the IHS made out of? Nickel plated copper or something?
2) Can I use Liquid Ultra on both the die-IHS interface and the IHS-waterblock interface? My only other TIM is a 5 year old tube of AS5. Liquid Ultra on both would be better than that, right? Any reason I really should order a tube of Pro?
3) What kind of voltages are people running? My 3770K is currently at 48x100MHz, 1.465 vcore, and it's hitting 95C and failing Prime95 after about 15-20 min. I'm kinda scared to go too much higher on the voltage...but I don't plan on using the CPU for more than a year, so degradation isn't really a concern. But I want to avoid sudden failure. I've seen CPUz screenshots of people pushing 1.7+V...are those just quick validations, or are those Prime stable?

Nice! The new kit is doing better, glad it isn't the IMC.
I thought I might have degraded the IMC on the chip I delidded, but it just got really picky with the mount. 3 different heatsinks & 5 mounts later it boots 2600 & 2800Mhz memory again, thought it was done when I tried it cold & still didn't boot over 2400Mhz.

1) correct, & IHS is nickel plated copper.
2) should be OK for both surfaces, not really sure about ultra or pro, haven't tried either yet, waiting on a tube of ultra to arrive myself.
3) it varies, the chip I delidded wasn't great, running 4600Mhz at 1.32 now, it did 4.5Ghz at 1.22, going over 4.5Ghz it starts needing big voltage bumps. People pushing 1.7V on air & water are for quick validations, temps would likely go through the roof under load unless more extreme cooling is used.

Thanks. What about FSB OCing? I know you can't do much on IB, but +4MHz would get me to 5GHz. smile.gif Possible? Does it need a PLL voltage boost or something? You don't need more vcore when you bump up the FSB, right?

104 bclk shouldn't be an issue, & shouldn't need much if any extra voltage (it does increase the speed a bit, so might). Every once in a while you come across pci-e devices (HDD, graphics card, etc.) that don't work well with increased pci-e but those are pretty rare, haven't had anything myself that had issues under 110 bclk.

If it were me I wouldn't delid that 3770k. I would sell it and get another. Why? It just doesn't seem like a good over clocker and if you are going to go through the trouble of delidding a IB cpu to improve perofromance I think its wiser to do it on a stronger IB cpu.


If you can run Prime95 stable for 24 hours with no more than 1.2v on Vcore with 3770k at 4.5GHZ then I think the CPU is worth delidding for maximum performance.


Delidding and fixing IHS should cool it down but it wont guarantee over clocking stability.

A high Vcore with high temps isn't good in my book, you either need to clock it down and reduce Vcore or delid your chip to get lower temps and see what your chip is made of!

They even have allen head bolts that are as wide as a pie and weigh over 100 pounds, probably use for something larger that a street light post.

Try an auto parts store for good sandpaper selection. That's what I found here anyway.

hey, bro it seems my new 3770K chip is very similar to yours. 1.22v for 4.5GHz and around 1.30v for 4.6GHz ... what is your batch? mine is 3228B
have you clocked it higher after deliding to see how fat it can go? I plan to delid this one on tomorrow and use CL Ultra (had great results with it on former chip).
