4 memory chips = 64bit wide
8 memory chips = 128bit wide

there is also another issue
some of mx440 were sdram based. (SDR labeled)

make sure chips are ddr and 8 pcs.

While this is a way to guess its not 100% reliable, it depends on the memory ICs being used and Vram size on the card, Later model MX440 8x cards could get away with 4 ICs on a 128bit bus. The easiest way is to look up the datasheets for the ICs being used on the card which will quickly tell you the bus width if you add up the number of ICs and memory size on the card.

I have a 128bit MX440 card with 4 ICs and another with 8 ICs.

For certain though if it has 2 on the front to the right of the GPU die itll be 64bit, if it has 4 with empty pads for another 4 itll also be 64bit, if its a 32MB card it'll also be 64bit but there were 32bit cheap n nasty models too.

Original GeForce 4 MX 440 design was 4 SGRAM chips, 2 on each side, which is still 128-bit.

Usual suspects of 64-bit bus are low-profile PCB or missing memory chips.

Thanks a lot for the info. That's good to know that there are ways to find it out. While browsing around I found that sometimes the mx460 can be purchased at a similar price of the 440.

Is the method for identifying a mx 440 also working for the 460?

As far as I kow, MX460 is always 128-bit. I have never seen a cut-down MX 460.

MX460 is a 128bit card, no need to identify it !

The MX460 is the better card as its clocked higher, but it never really sold that well back in the day so they are a bit harder to source, but if you find one at a good price grab that instead of the 440.

That's good to know. In that case, the mx460 would be a better choice in general. It is more powerful and no need to worry about getting a gimped version.

There indeed rarer on eBay compared to the mx440 but I found 2 Medion branded ones at a local trading platform for 25 Euro.

25 each ? or for both ? . .grab both and keep the other as a spare or ... throw it on eBay for 50 Euro and cover your costs.

I wanted GF4MX cards to fill gaps last year and took a look at the mess and went "screw that" and bought a couple of Quadro NVS cards for $10 each. Basically 128bit 440s.

25 each. I have contacted the seller already to say that I am interested,.

I see. It is not the first time that I have heard that some people used the quadro cards as cheap substitutes. Did it work well for you?

Well they seemed okay on the quick roadtest while I got them, the gaps they were intended for are still about 7 builds down the chain though so might be a while. I was getting nervous about anything AGP price exploding, like anything PCI had.

Yeah PCi cards got price hiked by a lot, not 100% sure why.

The price hike in the retro scene can be really scary. Because the hike is such unpredictable. Things that were very cheap a fear years ago are very expensive now.

And thanks for the info about the Qudro quard. My interest in that card is academical. Pulled the trigger for the medion branded mx 460 card I have mentioned above yesterday.

I think the 25 euro are well invested. Despite the bad reputation the card had during it's heyday, the specs are quite good and it should serve me well for my gaming needs.

Medion cards have usually lower specs. So I'm wondering what is the GPU/MEM speed of this card.
