very helpful guide thank you!

show me a picture of the back and I will show you

Could you show me now mate ?

....big snip....

Below is a chart that shows the optimal voltage settings which you should aim to better:

You should try to fall under these voltage ranges or slightly above to stabilize your OC, these are the recommended voltages per frequency, however the CPU I used is very good it seems, so you might need more voltage than I did.

....big snip....

If you have any questions please feel free to ask.

Thanks so much for your thread.

What are you suggesting one use for cooling to achieve the above recommendations?

I'm at 4.7 on air (D14) with 1.26vcore....but the hottest core is about 70*C under linX load.

I set now a relaxing 4.3 Ghz @ 1.12 vcore ( 3770k 3226B987 ) and i see much difference with temps in full load...absolutly i will made the IHS TIM mod soon

[my87csx481]

I did it. Over this past weekend. Liquid Metal Ultra between chip and IHS. The separation, for me, was easier than I thought it would be. I used one of these:

Don't laugh.... I tried some MX-2 I had laying around first....virtually no change in temps from stock TIM at the same clocks and voltages vs. MX-2 between chip and IHS and between the IHS and heatsink. Now, the hottest core dropped about 9*C using LinX load (using the ultra), and PK-1 between IHS and heatsink.

[hersounds]

That's great... I need 9-10 *C less soon !...the spring & summer it coming!

[my87csx481]

It seemed to scale too....pretty much right at 9* less at idle, and at load....with the same voltages. (I can supply screenshots if people are that interested.)

Just take your time, and work the corners first. After all 4 corners, the sides come pretty easy....for me anyway.

Please report back. I'm curious to see what you end up with.

yeap bro ! first I have to find if I catch Liquid Metal Ultra Here on Buenos Aires

[my87csx481]

I think frozencpu.com will do it but, probably by wire transfer only....maybe you can contact them. Seems that cool laboratories does not distribute to South America.

Sorry man.

Weird mate i had like 11 chips and did many times the IHS removal ALWAYS changing stock tim to MX2 and dropped always 10C...no need of fancy paste but sure to remove the crap one that comes with the chip

[andressergio]

yeap bro ! first I have to find if I catch Liquid Metal Ultra Here on Buenos Aires

amigo no need at all that liquid ultra use MX2 or MX4 any paste will make better results as isnt the tim exactly is that the stock tim on intel its A LOT and doesnt make real contact with die, so...

u can see it clear here with my chip what i mean

[hersounds]

yes bro i understand thanks for reply

[andressergio]

yes bro i understand thanks for reply

[my87csx481]

I did leave out something that may be important.

When I pulled it apart the second time to remove the MX-2, I did not like what I saw for contact. It was much like andressergio's picture, and what I had for contact from intel. So, I did lap the IHS surface that contacts the wafer, the one with all the black stuff on it. I cleaned it well the first time, but just before installing with liquid metal, I lapped it just until copper showed through the nickel plating. Maybe this is where my gains were achieved.

If I ever pull it apart again, I will test with MX-2 (or something similar) again.

Very nice guide.

Im unsure about a thing tho:

The voltages you should change for high memory overclocking on Z77 on air is the DDR Voltage, and if you like you can try increasing the VCCIO(VTT) and VCCSA(IMC) the VCCIO (VTT) can help with memory OC, however you will also need to increase VCCSA along with it on these GIGABYTE Z77 boards (except on the Sniper M3). If you want to increase VTT you need to increase IMC voltage to within 0.005v below it, so 1.1v VTT would be 1.095v IMC on these GIGABYTE boards. However I didn't really need to change it much at all

Im trying to see if i can get my ram stable at 2400mhz, and i thought about trying to change VCCIO. But VCCIO(VTT) is at 1.05v stock and VCCSA(IMC) is at 0.925v stock. Does that mean i have to bump the IMC all the way up to 1.055 if im going to try 1.06 VTT?
Im using a 3570k on a Z77X-UD4H board btw, and hynix BFR ram.
