Naw dude, the displayed memory speed is different from the actual. IIRC, you multiply the speed by the series of RAM (i.e. for DDR2, you multiply it by 2, for GDDR3 you go by 3, GDDR5 by 5, etc.)

Here's a hint, uninstall Catalyst, it's a bad control center, it hogs resources, and I haven't found a use for it. Next time you update, download display driver only.

GPU-Z for specs, and ATiTool and ATiTrayTools for settings/overclocking. Much better IMO.

Actually I don't think you multiply the speeds based on the generation of DDR.  DDR was still just multiply by 2, same as DDR2.  They're just incompatible with other DDR generations is all, it's still Double Data Rate, regardless of DDR1, 2 or 3.  Now _dual channel_ DDR2 vs _triple channel_ DDR3 is another story.  But I don't think graphics cards make use of that tech.

I was reading about some GDDR5 (the 4890, perhaps?) and the clock was 8 or 900 hundred something (3000 effective) I don't know how they factor it. I didn't really do any math when I wrote that, I just estimated.

Re: Graphics Cards Discussion
What the hell are you all talking about?

HD3870... one ****ing ninety dollars? http://www.newegg.ca/Product/Product.aspx?Item=N82E16814161251
The HD4670s are slightly slower than the old 3870--and much cheaper than what you paid. Hell... HD4830 is $108 CAD. http://www.newegg.ca/Product/Product.aspx?Item=N82E16814161260
You got ripped off if you paid that price...

And yet, why anyone would NEED all those useless features is beyond me.

Re: Graphics Cards Discussion
They're both 1GB cards--GDDR3 v. GDDR4 doesn't do much. Similarly, 512MB v. 1GB doesn't do much except at or above 1920x1200. And you can overclock that HD4670 if you really wanted to--lower power draw, easy overclocking, &c. And there's the HD4830 512MB for still a fraction of the price, which is a good bit faster than the HD3870.

Re: Graphics Cards Discussion
While High Max may not be the most knowledgeable person on HLP about video cards, he seems to be happy enough with his purchase. There is no need to rub "bad buy, shame on you" on his face. Let it go, really.
