Radeon.....No Hyper Z?

[jcwagers]

Hello! I ordered a Radeon 32 meg DDR card on Monday for a friend of mine. He's currently running a 366 celeron with a 4 meg Riva 128 video card. The site that I went to to order the card was newegg.com since they had free shipping. I was just noticing today that it says the Radeon has no Hyper Z? What exactly does this mean? I thought they ALL had Hyper Z.....guess I was badly mistaken! He's planning on upgrading to a 1 gig or higher Athlon in a couple of months but I was wondering about this Hyper Z thing. I know it makes a difference.....I just don't know how much....and WHY some of the cards don't have it. Any ideas? Thanks in advance!

there are supposed to be a few registry changes you can make to enable hyper-z

I've seen that some value editions of the Radeon line does not have HyperZ enabled by default. But since HyperZ is a software/driver thing it can be modified. A seemingly asia-only version of the card called Radeon LE can get HyperZ enabled this way: http://www.geocities.com/tnaw_xtennis/RadeonLE-H.htm

It's likely that the same operation works with any other Radeon cards currently having HyperZ disabled. I guess that the Euro/US version Radeon VE has the same little issue.

HyperZ is enabled with these keys:

Thank you guys very much for your help! We'll try that once my friend's card gets here! If I have any more problems, I'll know where to come to! Thanks again!

That card is a Radeon LE. It also has a lower clock speed. You can use Powerstrip to bring the speed up to that of a normal card. On the C366 I don't think it will matter. Once you upgrade, it will.
