Default In my photo - which number is Phase Regulators?

Hi guys,

EK never released a waterblock for the 1080 Classified.

But decided I'd take a big risk and buy a EK 780ti/980ti Classified block and see if I can force it to fit :-)

If I can get it cooling everything properly this could be fantastic news for many classified owners (I intend to document my experience)

Anyway I have a few questions regarding the VRM. (Hope you don't mind me asking)? :-)

In the EK instructions it says:
"EKWB recommends using small drops of thermal grease on each phase regulator (that is being covered with thermal pad) in order to even further improve the thermal performance of the water block."

1.Which number in my photo corresponds to the phase regulators?

2. Which numbers in my photo heat up the most (need to be cooled)? I am trying to coordinate best possible thermal pad placement :-)




Thank you so much :-)

Nick Peyton

I think the EK 980 classy block may be a better choice than 780ti/980ti classy block.
Also, it's much cheaper now on ekwb.com/shop than 780ti block.

Thank you,

I received my 780ti/980ti block yesterday.

But unfortunately I just received an email from EK with the following picture showing the memory modules on the left not fully covered as well as possible problem with the circled resistor (although I don't believe its much higher than the memory chips.

Here's the picture: (showing limited coverage)


I have wrote back to EK now; asking them to check measurements with 980 Classified as you suggested :-)

Thanks :-)

Part No.4 and No.5 need cooled well, very hot, sometimes higher than 100℃.

Just checked with EK.

EK 980 classy block won't fit due to the cold plate.




Thanks for suggestion though much appreciated :-) so its back to the 780ti / 980ti classy block which still looks like the best option

I am working with EK_Grega to find a workaround for the memory issue.

And to check if the "step" for memory on the block is in the way of the circled resistor. (It looks from picture above that it *just* misses it by a ball hair) lol.

Won't find out until I try it physically - will keep you all posted :-)

I've noticed that my memory temperatures (on the GDDR5X chips nearest to the VRM) run about 20c hotter than the all other memory chips on my card) under water.

In the pic above I'm making good contact with the block on items numbered: 4, 5 & 6.

But no contact at all on 1, 2 & 3. Would getting some extra pads to those parts help temps? If so which ones should I concentrate on the most?

I also watched a short PCB breakdown video on the 1080 Classified at "Actually Hardcore Overclocking" on youtube and he 'circled' everything between 2 & 6 as being part of the VRM.

What is number 1 and do they heat up too? (They are closest thing to my hottest memory chips).

P.S. I'm not looking for something for nothing.

If you read my post here you'll see why (might actually be quite impressed lol for a newbie ). :-)
