Unfortunately, I don't have any benchmarks...yet. I just reformated my hard drive for my new mobo and card, so I only have COD4 and Crysis installed.

On that note, how do I run that Crysis timedemo/benchmark thing. is it in the crytek folder or something?

Thanks for far...

Install it.

It's super easy to run, I don't think you'll need help in doing that.

got it, running it in a sec, thanks

I decided to hack it up. What originally was stopping me was the MOSFETs on the back of the card. Since the heatsink is a full cover block, I couldn't install my HR-03 GT without making/finding a heatsink for the back of the card.

So, onto the pictures. Sorry 56k users

The beast, for reference:


The dirty, naked beast:


All cleaned up:


A sexy shot of that 0820!? Still confused as to what that means:


Closeup of the RAM:


The villains keeping me from switching to aftermarket sooner:


And the saw comes out! MUWAHAHAHAHA


Heatsink: "No please, let's just talk this through, I'm sure I can help you, please noooooooo"


Too late:


The underside, solid copper is a plus, super easy to hacksaw through too:


I think it looks better like this actually


The other half:


The other half's underside:


Fan porn:


I decided to mount the fan back on. It could only help, right?


Now with the HR-03GT:


Mounted in my system with a 120mm Tricool from Antec:


Forgive the dust please:


Trying to show how close it came to the chipset heatsink. The fan is actually touching my Wifi onboard:


A shot with long exposure:


And the idle temp, original it would hover between 68-70C. This is with the tricool set to Low. On high it averaged around 35C idling. Not bad considering my ambient room temperature is around 32C:

Time to volt mod moot! I'm glad to see you finally brought out the hacksaw. I was waiting for that lol.

Insanity

Nice work!!!

hmm, my HR-03 GT is supposed to arrive tomorrow.. I thought it is supposed to come with some heatsinks and stuff for the mosfets. hope i dont have to break out the hacksaw too heh

What's the highest clocks so far on the 4850? I haven't done TOO much tweaking but this is what I've ended up with after about 30 minutes of clocking:

I might do a volt mod on it. I'll wait until a version of Rivatuner that works with these cards is released.

It comes with the heatsinks for a 8800GT/GTX. You might have to get the saw out

You could always try running without heatsinks on the MOSFETs, I just wouldn't recommend it.

[Emraith]

well damn, wish i knew that a few days back when i ordered it. it lists the 4850 on their compatibility list now.. oh well, guess i'll see whats up tomorrow when i get it

[Mootsfox]

Oh, the heatsink fits and works wonderfully on the core itself. You might be able to just angle the fan enough to blow across the MOSEFTs to keep them cool.
