lol, people gave me a weird look last time I mentioned that and thought I was joking (in some other thread here...)

Kepler cards for instance can be bios modded and they are all the rage, but the gains are really small...I'm glad I sold the 670 ftw I had. Boring card is boring to oc and bench.
I have a no name passive 8400 gs (ref design 99% sure)

..well, I dunno, there are ways to make them (670ies) 'less boring' and tease Titan owners and others biggrin.gif ...you just have to be nice to them thumb.gif

Nice score! biggrin.gif

I know what you mean, I like a challenge once after a while, but Kepler is not 100% there for me....

I think I'm gonna try the vise+hammer delid method soon.
What do you guys think?

256bit bus + locked voltage makes Kepler suck.

Kepler should have came 384bit bus an unlocked voltage.....

I went from 2 4gb 680s to 3 7950s and the 7950s net me 50% more FPS Plus pay for themselves every month wink.gif

What do you guys think?

...on the vise+hammer, I am wondering whether you should use a heat-gun first re. the silicon...other than that, the only thing that worries me is that the IHS hits the die when it flies off

...on the vid cards, I have a unique problem...per earlier posts, I now have two ROG boards (MVE, RampIVE)...I also have a friend who lives a floor below me who has a new software company involved in building software for rendering for 4K monitors...as such, he currently has 28 boxes of Gigabyte 7970ies behind the couch, awaiting deployment in the render farm...two per machine but NOT in CF to mimic 4K

...that gives me an idea to try a few out (bin them biggrin.gif) on the second mobo...fortunately /unfortunately, I'm still waiting for the 3970x to arrive so I have a few more days to ponder this predicament....though I could just pull the 670ies for a bit over Eastern...oh dear headscratch.gif

UM... could I have his address. You know, just to.... ask him a couple tech questions?????? thumb.gif

Too many posts to dig through... (Though I made it through a few hundred!)

Has anyone tried direct water-cooling of the die?

This would have to be a (Negative pressure) design. {Sucking water through, as opposed to trying to push it through.} I say this because the setup would require placing the water-cover directly mounted onto the PCB, minus the contact plate. The negative pressure would also ensure that any possible "boiling bubbles", would be evacuated. As opposed to a positive pressure system, which would never push bubbles out, they would simply collect and twirl. The negative pressure is important, because it would not require massive pressure to hold the cover onto the PCB, as it would have a natural suction-cup effect to assist its grip. Thus, also allowing you to completely silicone the whole PCB/Water-cover assembly too.

I imagine this could be done with a modification to the original cover, if it were to be "hammered" into a slight dome-shape over the die, and connectors being soldered on each side for the water-inlet and water-outlet.

I am not talking about uber-chilling it down to zero... simply room-temp regulated water temps, or a standard setup with a simple radiator and a reservoir.

I know that the components on a GPU (the surface-mount resistors) are all protected by a thin layer of epoxy, as I see everyone smearing the electrically conductive thermal paste all over the components, without harming the function. So I imagine this could also be extended to the GPU as-well. All the GPU's I have seen, have no covers over the die.

Anyone brave enough to try it? (Or oil-cooled, if you prefer. The electronic mineral-oil found in microwave capacitors is perfect for this type of cooling, and is non-conductive, as water potentially is.)

...He won't be home...my GF and I will buy him his favorite steak dinner and his favorite restaurant, along with some nice beers, and then I shall bring up my 'R+D' needs re temporary 7970ies biggrin.gif

If some is going to go the vise method, I would think that rotational torque would put far less stress on the pcb than the shear force created by a hammer blow. If the glue can be “knocked” off, one would surmise that it could be twisted off with less force.

The question is how to turn the pcb. A block wood with a pcb sized cutout would work, but that seems like too much trouble.
