I have a CT6670 and it's 12MB.

Thanls. Hmmm... What CT-Number can the 8mb might have?
Are they rare, because I have not found any numbers other than CT6670.

According to this old topic it could be CT6670 or CT6671 for 8mb models:

Can a Voodoo 2 8MB or 12MB be identified, physically?

The only sure way to know is to look at the card's back. If the top row of memory chips is missing then it's an 8mb Voodoo 2.

EDIT - Here are two links from tdfx.de to help illustrate the difference:

Thanks...
Funny that even not Google have picked up that old Topic here on Vogons.

If the back of the card is fully loaded with chips; then it's a 12MB model for sure and with a few missing it's indeed 8MB. But if the back is totally blank you either have a very special Voodoo 2 6MB (which could be a Creative sample actually) or you have a very late Voodoo 2 like the Evil King 12MB. The latter uses higher density memory chips so it needs just half of the chips to get 12MB 😀.

On the CT-number subject; I have both 12MB and 8MB models with CT6670 model numbers.

STB BlackMagic 3D 12MB also has only frontside memory. I had problems with original drivers presenting it as a "6MB" card though.

Thanks... Hmmm... No 100% way to tell the amount of ram by the "CT6670" number then?
And there are samples in the wild, with 6mb ? 😳 Da**.

And yet I don't see any 6 and any 8 cards out there in the wild. Everything is 12mb (say's every seller).
I guess.. If the 8mb is rare, the sample model with 6mb is even more rare.

I have CT6670 with 8MB and 12MB too, so the number can't tell you the amount of memory.
However my 12MB CT6670s are all fully equipped with memory chips and the 8MB ones are missing a row of chips.

The 8MB model isn't rare. I've seen a lot of them. I'm not sure which version has been manufactured more but something tells me that the 8MB version was actually more popular back when the Voodoo 2 was new (at least in my area).

And yes; Voodoo 2 6MB does exist but only engineering samples, not production.

By the way, is there any easy method to distinguish STB Blackmagic 3d and STB Voodoo2 1000?

Have not much personal knowledge of it, really. And now I understand I made a mistake. My STB card probably is a Voodoo2 1000 (I was recorded it in my spreadsheet as Black Magic but not sure about it anymore). I've seen some references saying that STB Vodoo2 1000 has 12 front side chips only, but BlackMagic has 24 (12 each side, just like most other V2 cards).

Perhaps people are hiding them away, untill all 12mb are sold. Then we will see a flod of 8mb on eBay. 😁
Most V2's on there is 12mb. And the only ones I have seen in Denmark is 12mb.

A Google search for CT6670 gets this result:

Check out these two links from tdfx.de:

As it turns out, you're right 😊

earlier on i have seen a lot of 8mb samples, and since the v2 was extremely expensive i do believe the 8mb models were more popular in the beginning as they were a bit cheaper. Later in stores i only saw the 12mb version but prices had dropped a lot by then.

every now and then i see a used 8mb one for sale but mostly they are 12mb versions now.

I have nine v2's myself but all are 12mb. I don't even look for a 8mb card eventough it should complete the collection a bit more. (will pick one up at a fleamarket when i see one)
