hang on a minute , has electrolyte turned into scott here , the signature is the same :disturbd: :disturbd: :disturbd:

Re: GeForce 4 MX440 showing as an MX 420?
 

Yes I have, Richard kindly changed it for me (got sick and tired of that nickname :) )

Re: GeForce 4 MX440 showing as an MX 420?
 

There is not alot of difference between the mx420 and the 440, the latter has a slightly faster core speed, and 128bit memory bus whilst the former has a 64bit bus (going back a fair bit in technolgy there) the 420 has 2.7GB/s of mem b/w compared to the 440 which has either 6.4 or 8 GB/s (depending on if its agp4x or 8x) High end cards these days are in the region of 30+GB/s
http://www.nvidia.com/page/geforce4mx.html has all the specs on the 4mx, note no pixel or vertex shaders, as quite rightly said its a modern (aka cheap) geforce 2 gts. Solid performer really on older games, nothing fancy but will be 'eck of alot faster than the sis card.

Technology comparison with the rest of the '4 series

nfiniteFX (II) is there name for pixel and vertex shaders, ie dx8+ compatibility

Re: GeForce 4 MX440 showing as an MX 420?
 

OK I am really confused now, and I mean VERY confused (I hope bifta can help with this :( )

Just looking at the specs of the MX420, and accordingly the GPU runs at 250mhz, which mine does, but the memory of a MX420 is 166mhz, when mine is 333mhz?

Is this a OEM card since it was from my mates Dell Dimension 8200 or is it mixed with a 440 and 420? Or would looking at the GPU find what it is? :erm:

Re: GeForce 4 MX440 showing as an MX 420?
 

166 = 333DDR, i.e. that's correct, and if I were you, I would forget about overclocking a card that has passive cooling or you might end up testing your smoke alarms, and as Richard said, it's a 420, either his machine has reported it incorrectly (unlikely), he's sent you the wrong card, he's mistaken, or he's lying.

Re: GeForce 4 MX440 showing as an MX 420?
 

But I thought MX's had SDR memory, not DDR :erm:

Re: GeForce 4 MX440 showing as an MX 420?
 

DDR is SDRAM, Double Data Rate-Synchronous DRAM, main difference being that it supports double the transfers per clock cycle, and the 420's that I've seen do have DDR memory chips.

Re: GeForce 4 MX440 showing as an MX 420?
 

Ahh right, do you know any good cooling products that would fit it so I could overclock it? :)

Thanks :D

The phrase "you can't polish a turd" springs to mind, but if you're really set on shortening it's life then

will cool the GPU, but the memory will probably also need cooling if you're going to overclock it

Hardly worth it, you may as well put the money towards eventually buying a decent video card.

Re: GeForce 4 MX440 showing as an MX 420?
 

I probably will :)

Re: GeForce 4 MX440 showing as an MX 420?
 

Most 420s do have SDRAM but a few might have DDR.

Re: GeForce 4 MX440 showing as an MX 420?
 

From a couple of overclocker sites & forums.

280/366 (or 183, if it reports actual, rather than DDR clock)
275/365

So the overclock achievable is a little less than 10% on the RAM - not surprsing, since it's 6nS RAM which is right on it's 166 (333) clock rating - and no ramsinks, and about 10% on the core, passive heatsinked.

Maybe there might be a little more in the tank, if heroically cooled, but I wouldn't expect much.

Unless you're aiming for records for this particular card, I'd say take an easy overclock, and come inside of those figures, maybe 265 / 350, or don't bother - there isn't enough overclocking reserve to make much difference - unplayable frame rates would still be unplayable, and some of the tests show 0-2% gain from a 10% overclock, others show pretty well the full 10%.

Re: GeForce 4 MX440 showing as an MX 420?
 

When doing a test a few days ago, I got it to 300/393.

Re: GeForce 4 MX440 showing as an MX 420?
 

Indeed - but some people will try to get even a 1 or 2 fps increase - just for show ;):D
