GeForce 4 MX440 showing as an MX 420?
 

Topic says it all really. My mate sent me his old GeForce 4 MX 440 (which supports pixel shading, and vertex shading) but my PC reports it's an MX 420. But I looked at the image he sent me of it, and it looks more like a 440 than a 420. I have emailed NVidia about this, but have had no reply yet. Also since it is using the 420 drivers, it isn't using the cards "full" memory bandwidth. I have put an image to show you.

Any one know why it is showing as a 420?

Re: GeForce 4 MX440 showing as an MX 420?
 

i assume it showed as a 440 on his pc then ???????????? :)

Re: GeForce 4 MX440 showing as an MX 420?
 

Yep, with Pixel and Vertex shading.

Re: GeForce 4 MX440 showing as an MX 420?
 

how about the driver then ??????????? :)

Re: GeForce 4 MX440 showing as an MX 420?
 

The driver is the same for all GeForces, he said it said GeForce 4 MX 440. Mine says MX 420.

Re: GeForce 4 MX440 showing as an MX 420?
 

of course , silly me :rolleyes: , how about trying it in a different pc and see what happens :)

Re: GeForce 4 MX440 showing as an MX 420?
 

1. This is the only desktop I have, and my mate lives in the USA :(

Re: GeForce 4 MX440 showing as an MX 420?
 

Me and dilligaf have tried to search for it using the FCC number, but we can't find one on the card. Looks like NVidia never put one on it.

Re: GeForce 4 MX440 showing as an MX 420?
 

1 last roll of the dice for me then , have you tried removing it from device manager and rebooting , i aint saying it will work but you never know :erm: :D :D :D :D

Re: GeForce 4 MX440 showing as an MX 420?
 

What card was you using before this one?

Re: GeForce 4 MX440 showing as an MX 420?
 

I was using a Pine 3D Phantom XP SiS 315 64MB 4X AGP (which ran in 2x AGP)

Re: GeForce 4 MX440 showing as an MX 420?
 

have you removed all the drivers for that card?

Re: GeForce 4 MX440 showing as an MX 420?
 

Err no I didn't actually. I thought 2000 would remove them automatically.

Re: GeForce 4 MX440 showing as an MX 420?
 

I don't think they actually get removed....maybe there is some kind of conflict

Re: GeForce 4 MX440 showing as an MX 420?
 

Removed the SiS drivers, still says MX 420.

Re: GeForce 4 MX440 showing as an MX 420?
 

It probably is a 420 then, with 64MB of SDRAM.
It supports DirectX 7, with no pixelshaders.

Re: GeForce 4 MX440 showing as an MX 420?
 

My mate said it's a MX 440, it shown MX 440 on his machine and support Vertex shading and Pixel shading.

Re: GeForce 4 MX440 showing as an MX 420?
 

It does not have Pixel Shaders.

Re: GeForce 4 MX440 showing as an MX 420?
 

so it looks as though it was total confusion for nothing :disturbd: :disturbd: :disturbd:

Re: GeForce 4 MX440 showing as an MX 420?
 

Have you run AIDA32 or similar to see what it shows up as?

Re: GeForce 4 MX440 showing as an MX 420?
 

Yes, everything reports it as an MX 420.

Re: GeForce 4 MX440 showing as an MX 420?
 

Go to Start > Run then type "dxdiag" and press Enter.
Click on "Save Info" then copy this bit into a post:

Re: GeForce 4 MX440 showing as an MX 420?
 

i wonder if it might be a mx420 then , sorry but i reckon this has been a wild goose chase :( :erm: :( :erm: :(

Re: GeForce 4 MX440 showing as an MX 420?
 

It's definitely an MX420, the hardware wouldn't lie about it.

Re: GeForce 4 MX440 showing as an MX 420?
 

The MS-8878 (MSI) is either a MX420, or an MX440SE (slow edition)
http://www.msicomputer.com/product/p...0D-T&class=vga
http://www.msicomputer.com/product/p...SE-T&class=vga

The Geforce 4 MX does not support pixel shaders at all (NV17 chip) - and The NV18B (8x AGP, second version) has, so I read, a limited degree of vertex shader support.

They are basically a glorified version of a Geforce2, and have little to do with a "real" Geforce 4 - a lovely bit of misleading numbering by Nvidia!

Lovely PCI ID that, tells you a lot
VEN_10DE&DEV_0172&SUBSYS_015A10DE&REV_A3
Breaking it down:
VEN_10DE - That means NVIDIA
DEV_0172 - That means a GF4 MX420 (the 440 is 0171 and the 440SE is 0173)
SUBSYS_015A10DE - Most likely unique to MSI card (015A) + Nvidia chipset (10DE)
REV_A3 - Chip or card revision is A3

Re: GeForce 4 MX440 showing as an MX 420?
 

I may aswell overclock it with the Omega drivers. I heard some people got very stable and good performance from it. I'm gonna do it in 5-10mhz, starting with the GPU then the memory :)

Re: GeForce 4 MX440 showing as an MX 420?
 

go for it , it aint gonna cost a lot to replace if you fry it :disturbd: :disturbd:

Re: GeForce 4 MX440 showing as an MX 420?
 

Well every one else who has done this has done it in 5-10mhz's, starting with the GPU first until it actually crashes, then role back to the last stable one, then the memory the same thing. I don't know any one who has fried it doing it this way, at least I have my musketeer to help me with the temperature. Gonna stick it's sensor on the heat sink, last person I know it stayed around 35C (and that was a 440).

Re: GeForce 4 MX440 showing as an MX 420?
 

are you really 16 ????????? , or 16 going on 60 :disturbd: :disturbd: :disturbd:


if you are 16 then lighten up and try and see the humour in ppl's posts or you are gonna have a tough time ahead of you ;)

Re: GeForce 4 MX440 showing as an MX 420?
 

:erm:

Re: GeForce 4 MX440 showing as an MX 420?
 

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
http://www.nvidia.com/page/geforce4.html
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

Re: GeForce 4 MX440 showing as an MX 420?
 

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

http://www.overclock.co.uk/customer/...=16752&cat=413

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

http://www.overclock.co.uk/customer/...=17622&cat=413

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

Re: GeForce 4 MX440 showing as an MX 420?
 

did it start to smell funny :D :D :D :D


tbh i wouldnt waste your time , you aint going to gain a great deal apart from a fire :disturbd: :disturbd: :disturbd:

Re: GeForce 4 MX440 showing as an MX 420?
 

If this happens can you take a picture please ;):D

Re: GeForce 4 MX440 showing as an MX 420?
 

Nah, I only did it to see what the performance increase would be. Which wasn't much, about 5-10 3DMark03 points, so I just leave it at it's default (250/333)

Re: GeForce 4 MX440 showing as an MX 420?
 

But I wanted another picture for my collection :)

Re: GeForce 4 MX440 showing as an MX 420?
 

of flames sprouting from a pc's vents :D :D :D :D :D

Re: GeForce 4 MX440 showing as an MX 420?
 

More like PCI slot fan vents :disturbd:

Re: GeForce 4 MX440 showing as an MX 420?
 

3Dmark 2001 would be more relevant - anything less than DX8 hardware only does the first test of 3Dmark 03, and does poorly at that - with my old 2MX, I got about 100.

Re: GeForce 4 MX440 showing as an MX 420?
 

Give up :disturbd:

ATi 4.9 Cats are out

Re: GeForce 4 MX440 showing as an MX 420?
 

This isn't an ATI card.

Re: GeForce 4 MX440 showing as an MX 420?
 

Errr i know :erm:, i was just stating, its not like it deserved a new thread.

Re: GeForce 4 MX440 showing as an MX 420?
 

Just as well, as it's already been posted in a different one.
