Few questions, GeForce2 MX 400

[deleet]

OK! Here it goes. I have a somwhat old Chaintech GeForce 2 MX 400 (64MB version). Currently I can raise the Core clock to about 240 MHz and Memory clock to 390 MHz. I have quite a few fans on my system and the card doesn't go pass 35º C but I start getting image errors whenever I raise the speeds more than the ones shown above. My questions are:

Is there a way to raise the speeds even more?

I heard something about enabeling extra pipelines so that a MX version of the card becomes an Ultra / GT / GTS version. Is this true and how can I do it?

Thanks for your time!

Its hard to get those mx's to really perform because the memory bandwidth is a real bottle neck. you could prolly push the core higher, but unless you can get the memory clock any higher, your not gonna see much of a performance increase.
I had a creative labs gf2 mx 32meg.
I would push the core until it started artifacting and then drop it back down 5 mhz,
then i would push the mem up in 5-8 mhz increments until it started artifacting and then back off about 5 mhz, thats about all you can do without adding additional cooling.

Already did exactly that. I can't get anything else. I already have a huge PSU fan as addicional cooling. I read somewhere that these MX cards could be "unlocked" to GTS / Ultra cards.

I had an ASUS mx400 64mb and only got 240 355 with no fans tho. and thats was fun. I loved that card.basicaly no. You have reached the limit of what that card could do. unless... volt mod?

 

[Elwood1984]

i think that involves flashing the card's bios, which i have never done. You may want to do a search on the forums about that. also, does the card have a decent heatsink? thermaltake has a pretty good video card cooling kit that fits the old school geforce 2's

I have never heard of a mod that will make a geforce2 mx to anything else. Better cooling might get you alittle more but not much.

You could volt mod it. That way if you fry it you have a good excuse to upgrade.

 

[deleet]

Volt mod. No idea what it is and how to do it. Help?

try this

try it out and post your results

I have 2 gf2 mx400's. One uses ddr ram and the other uses sdram. The one with sdr has no heatsink and overlocks like a beast. It got to 280 core and 180 mem. This sounds low, but is twice the bit pathway of the ddr models, so sdr and ddr performance is equal. I actually burnt my finger on it though, and it still works flawlessly. The gf2 mx with ddr memory I have never overclocked.

 

[denz_1]

hmmm Yea mine was weird. Mine said it was sdram but ran at 334ram stock. It was basicaly a gts but cheaper.

 

[Quailane]

Because some had sdram and some had ddr, applications don't know what to say the ram speed is. You are looking at the false ddr speed.

was.... sold it. Bought a 6600gt... JUST NEED TO GET IT!! grrr oh well

i have a gainward gf2 mx400 and i found a site that shows how to mod it to a quadro 2 leme check the url

check this out ^^^ all you geforce 2 users!!

I heard somewhere that that ddr ram on the mx's was only 64 bit, whereas the sdram was 128 bit, therefore there was not much of a perfomance gain with ddr, it was pretty much a marketing scheme. i'll see if i can find that info.

Still ran beautifully at 1024 x 768 med- high settings. I miss it

 

[denz_1]

on UT2004 that is
lol.. SOrry bout that

 

[cullam3n]

Hehe... reminds me of the days I had a PCI Geforce 2 MX200... man those were the days.

Pushed a mind-boggling 1610 on 3dmark01 with a Duron 800 and 256mb PC-133.

 

[denz_1]

What happend to the durons? The beat the hell out of the Celerons last time I cheacked But they have gone...

 

[Quailane]

Replaced by semprons, and they still do their but kicking.

 

[denz_1]

*smacks head on table* thats why there so cheap.... How could I miss that :s
