Sugestions for VooDoo based projects

[amp_man]

lecram, you truly are a f00l, its his first post[|)] he's just trying to catch you before you get on his back, just like you do everyone else. i think thats an error in his profile, notice that he also does off-road driving, i'm not sure if 13 year-olds can drive in austratia, but...anyways, we're getting off-topic. to bring up a topic from faconfly.de, would it be possible to create software anti-ailsing for the V4 to give it 4 sample AA, much like my Geforce 2 uses? and hank, I know you don't do software, this isn't addressed to you necessarily

to bring up a topic from faconfly.de, would it be possible to create software anti-ailsing for the V4 to give it 4 sample AA, much like my Geforce 2 uses?

This would be futile...EXTREMELY!
4xAA on the Voodoo 5 is slow as it is...then why would you go do that to the Voodoo4, which only has 1 VSA 100...but yes, it would be possible...

[amp_man]

I said software antiailsing, doesn't that mean that it's done be the CPU (I'm not positive, but fairly sure)? Also, the geforce 2 only has 1 GPU, although its core clock is a little faster (200mhz,@215), and the RAM is slower (333, @350).

[lecram25]

Yes, software...remember, "effects" done in software are slower than those done in hardware...so if 4xAA is dirt slow on a Voodoo5, I can assure you it's gonna be as slow, if not incredibly slower on a Voodoo4...you do the math...

[amp_man]

but wouldn't it also, theoretically (not taking into consideration the difference in GPUs and drivers, which probably makes all the difference) be slow on my GF2? but it isn't...

[lecram25]

Remember, the GF2 has HW TnL, DDR Ram, and, I think, more bandwidth than the Voodoo4/5...

[amp_man]

Geforce 2 GTS specs:
Memory Interface:     32mb 128-bit DDR
Pixels per Second:    800 Million
Memory Bandwidth:     5.3GB/s
Triangles per Second: >25 Million
GPU:200mhz   RAM:333mhz

what are the specs on a V4, just for comparison?
here's what I know:
Memory Interface:    32mb 128-bit SDRAM
Pixels per second:   333-367 Million
GPU:166mhz   RAM:350mhz

Hey Lecram i all it was was a stuff up when i logged on and it reset my dob and pic (i wondered why it never showed..

Just for the record where are you student and what's your age...
And how far through your studies are you..

Now back to the real serious stuff..
Is it actually possible to piggyback the ram or do you need to modd the card evn more???

And Lecram if you feel a need to reply please could you attempt to be civil about it PLEASE...

Thanx in advance to any and all for thier input..

Since modifying the v5500 to 128meg is possible,i was wondering if moding it will be a major feat anot,as if ulook carefully at the pins sticking out of the ram,is too fine will that be very difficut to unsolder?Next is i think all sort of sd-ram should be able to use as since the design should be the same.

@Phozy
modifying the V5 to 128 would be possible, but it would be a very delicate and time consuming process. lets see, about 45 pins per side of an sd-ram chip, less than 1mm apart and really hard to even count, let alone sodier, times 2 sides, times 8 chips, that's (45*2*= about 720 pins to sodier, none of which can touch another. I do sodiering quite a bit, and I really doubt Hiero's story.

EDIT: @Cyberpunk: 2 things, first off, you initiated it, you came out directly challenging lecram. he's cool at the moment, lets hope he stays that way. second, at 32, you would have been 8 years old when that PC came out, you must be rediculous to expect us to believe that, PCs weren't PCs they were Geek-Cs, not for 8 year olds. and a third thing, good luck on getting that 6000, last one on ebay went for like $1500 USD.

Piggy backing the ram IS possible, just need to bend one pin up and attach the last address line to it (and not both rams).  There are a few hardware mods that Hank was working on last I read on x3dfx ezboard site, that I don't think Hank has perfected yet.  I believe that one of the mods was near impossible to pull off because the attachment was under the VSA100's.  The real problem for me is finding the larger ram for sale.  I found some ram with the same exact pinout, with the one added address line which is a no connect on the original rams, but no one has a small quantity to buy......  Also a bit faster than the original rams.  I have access to a surface mount person here in the lab, and he says it would be much easier to remove the original rams and solder the larger new ones on directly to the board......

[amp_man]

can you give a link to hanks thread on x3dfx?

[lecram25]

Nope, it's gone...too long ago...

i dont doubt it. i think it is entirely possible. if i remember correctly, it has already been done by someone on the x3dfx boards a few years back (when i still visited.. )

another example of great soldering skills: some japanese guy took of the l2 chache chips of his p2 450 and soldered some new, faster chips on it. he then could clock considerably faster.

That the guy from x3dfxgamers modded the Voodoo5 is not confirmed yet as he never posted a pic. As he says his father owns a company which does electrical engineering. If that's true modding the card ( soldering the 720 pins ) should be possible. I think you need machines and you can't do that with your hands as the soldering points are simply too small.
