I completely forgot about rivatuner, i havent used it since i got my 6800GT.
Will update all this tonight, is furmark any good for testing? i see alot of folk on XS using and others saying not to, what do you reckon?

See post 19 for updates, will put in more overclocked results later.

Nice! Are you using the original PWM heatspreader as a backplate?
If you didnt i think you can squeeze a few more degrees, as a lot of heat is transferred to the PCB through the solder joints, and the PCB won't bend if you use more pressure.

I am not using any back plate, do you mean the one i cut the fins off?
I looked at this but it will not fit the holes are too far apart. But I can try anything else you might like to see on there.

I was on XS and dejanh pointed out that the type4 base is thinner than the others, the base should be a suitable length too. So that might be worth a read if you fancy a look.

You could simply use the one you took away from the HD4870? I think the holes should have just the right spacing!

About the Type 4: it seems you cannot slide the push pins to center them (they would stay in corners) and i doubt the base is long enough to cover all of the transistors; plus it doesnt have the sliding mounting mechanism so it won't even reach the holes.

I will take a look at the stock cooler when i get home, it looked like it was all in one piece but certainly worth a try.
I got her to run 3DMark @ 835/1130 last night a couple of times with no crashes or artifacting. I think i am getting near what can be done on stock volts though.

aw you know you may be right, i think the stock cooler is a monoblock

but you can always buy another HR09...

Hi there,

Decided to join this discussion here because I am really enticed by the results and because I found affiliate's attempt interesting as it is something I was trying to do about two weeks ago on my 4870 XOC BE but had no ability to level the HR-09

Considering that he seems to have solved that problem I really want to see the final solution

Now in terms of the Type 4 fitting better, the Type 4 does not have movable pins. However, the pins are placed as far back into the corners as possible which is what I found needs to happen to be able to mount the HR-09 using the PCB mounting holes. On the HR-09 I also had to slide the clips all the way to the end onto the heatsink itself, on the 61mm side making the total coverage length 61mm. Considering that the Type 4 is actually 61mm in length as well with pins pushed to corners, I do not see why it would not fit.

I do not have a spare 4870 to try this on now unfortunately but I picked up a Type 4 so that I can try it when I get my hands on a spare one. Affiliate, can you please post detailed pics of your setup? I am most curious at the detailed pics of the HR-09 over the VRMs and how they have been leveled

I know you already have WIP pics, but I am looking for finals.

Thanks!

Welcome to the forums.

I will add a bunch of photos tomorrow night and details of the non-standard/ghetto fixes i had to try.

If the E8600 arrives i will need to strip the whole thing out anyway to finish the HR05 review i started.

Welcome!

I see what you mean, and it could work as a backplate solution; but i fear that some of the transistors would only make partial contact with the base, as the cooler would not sit aligned with the little chips.
I suggested the HR09 Type 2 because it is possible to adjust the distance between the pushpins and sit it aligned.
