Default Gigabyte Radeon HD 4850 1GB Comment Thread

It seems like we have been giving passively cooled cards a good going over these days and I know a lot of you have been looking for reviews of 1GB HD 4850. We go one better with one of the only (if not THE only) passively cooled HD 4850 available in North America. Meet the Gigabyte GV-R485MC-1GI.

Some of the results are interesting to say the least.

You can find the review here: Gigabyte Radeon HD 4850 1GB Passive Review

Please use this thread to post your questions and comments.

Interesting. Factory Overclocked (mind you only 23mhz) Passivly cooled.

Also, the fact that it comes in with cooler temps with NO active fan blows my mind.

Seriously. That HSF must be rockin!

That will probably be the best HTPC card for a while. If I build a silent HTPC, that would be what I would buy. The passive temperatures fully justify the price.

SKYMTL, your AVIVO page on the reviews still mentions the 4670 vs. the 9500GT. You should change that up to compare the 4850 to the 9800GTX. Just a little copy/paste error, that's all. I know you don't have all the time in the world to write the same thing over again in this world.

Also, what I'd like to ask is why they put VGA integrated onto the card, instead of having two DVI-D with a DVI to VGA adapter. It was kind of confusing when you said "you'll see why on the next page", but the answer was kind of a detriment to the actual card itself. Doesn't VGA have less bandwidth than DVI?

EDIT: Let me add to this. The card produces digital signals, then converts to analog for VGA, then back to digital for DVI? Doesn't make sense to me.

Wow very impressive card, and a nice review as well.

The extra 40$ can somewhat be justified. Since converting a reference 4850 into a passive one with HR-03 would cost just as much, even more.

What I found interesting, is that fins from the heatsink towards the backplate actually protrude out. Innovative.

EDIT:The inclusion of VGA by default is good, since this is aimed at compatibility and function over duallink DVI x2 outputs. It's something that you can..stick it in the HTPC, and hook it up to whatever display you want. Plus it saves them money not including an adapter

I don't know about the HR-03 now. After reading the BFG 9800 GT 512MB ThermoIntelligence Passive review I'm surprised at how poorly that cooler performed.

I've seen that cooler before a couple years ago on a Geforce 86xx model. It was released kinda late and no one seemed to give it any notice.

I also want to thank SKYMTL for doing the EXTREME environment tests. I'm pretty sure he's the only one doing that kind of test on the interweb. It really shows us who's cooling solutions are top-notch. I reeeeeeeeeeeeally wish I could buy one of those multi-core coolers now.

Yeah I'm just trying to make a point, on how much it would take to convert a normal card into a half decent passive one.

SKYMTL thanks again for your review.
Just one thing puzzles me: temperature. I have a very good friend who works in service for our big Gigabyte reseller and I just speak with him, in low airflow this card reach 110C after 5 minutes of FUR and is throttling.
He told me that he has back in warranty more than 50 cards with temperature over 100C.
