Dear God do I want to see NCspecV81's results.

I can see why it would have been annoying to write in every post which brand you got and your results. I just figured a poll would be an easy and quick way to see which is most popular on this board, then I could go look up that card and find out why its so popular and then likely get it with confidence.

Well my Asus does 935MHz on stock voltage and 1GHz on 1.375V

reference cards get to about 950 core, 1100 memory.

factory overcloced cards are all relative, but the best out are sapphire vapor-x, zalman vf1000 and the MSI coolers.

sapphire & msi aren't released, the zalman is an aftermarket cooler.

Have any of you guys with the reference cooled 4890's tried taking off the stock coolers and putting on some of your own quality thermal paste, then reseating? Did it help temps?

[gurusan]

The reference thermal paste is usually pretty good. It's just that sometimes the application of it is sloppy. When I removed my Asus cooler to fit the waterblock I noticed that the paste was applied pretty nicely. Not too much and enough to cover the die.

I would say that unless your temps seem unusually high there's not much point in reseating the heatsink.

They zalman VF1000 is adequate for the 4850 but insufficient for the 4870.

As such how can it handle the 4890?

That's not true. The VF1000 can keep a 4870 at 60-65 under load, so I'd imagine it would be fine for a 4890.

However the VRMs need to be adequately cooled, and this can be done with a Zalman RHS70. I am running one along with my maze4 waterblock and it keeps VRM temps mid 50s under the highest loads.

those temps are higher then what i get on my 4890 with 45% fan >.> stock cooler

Yeah it's not ideal but the Zalman is much quieter. The 4870/90 reference cooler is not bad but it gets really loud at anything above about 35-40%.

That's why I love water Dead silent and 40C max load @ 1GHz
