nobody know what is the function of that capacitor? my voodoo4 seems to work fine without it..
only seems because direct rendering under linux is impossible to switch on, and under windows smetimes gl games freeze the system when entering 3d mode..

ome more thing to say. if anybody of this forum has 4Mx32 memory chips with the same number of connections in his/her hands, how can he/she put into the card?

Not sure about this one, might be wat we're looking for.

Very interesting German site: (I think)

Don't think this is of any value to us:

Stumbled across this one:

The correct Hyundai (Hynix now) memory chips Grin

@DenisF - just wondering if it's possible to 'mix' brands of RAM if you do this MOD, as long as... Roll Eyes

1. RAM is same size (4x8MB chips mixed with 4x8MB chips) Wink

2. RAM is same speed (6ns mixed with 6ns) Wink

The reason I ask is that I have a faulty V5500 that has some 6ns RAM on it - but it's NOT Hyundai like the V4500 needs... Undecided

...I'm thinking of doing the same MOD and the RAM chips match speed and size, just not brand name Tongue

You could remove all the RAM from the V4 and use all the RAM from the V5. Just a thought Grin

@paulpsomiadis
Yes, you can do ANYTHING to memory chips - different brands, different speed... When our Radeon 9500 with 2.5 Hynix RAM (re-soldered from FX 5600 Ultra) received Vmem=4V and half of chips burned, we just placed some 2.8 Samsung from Ti4600 on it.

Actually if anybody have questions regarding memory/gpu resoldering - feel free to ask me Smiley We'd done this plenty of times Smiley

@DenisF
Good work! BTW i'm not sure if V5 5500 will allow you to place 128 Mbit chips on it and will recognize them correctly... Though maybe its a question of bois hacking, i'm not a pro in software issues here - only hardware:)

@NitroX infinity
Funny. Checked that ENSIL site... It is possible to re-solder any BGA chips with open-type electric oven and hairdryer (well, average one won't allow you to give enough temps, so need to be modded or just to a bit broken:)) of heatgun.

Ah0y folks!

For those of you who have been wondering "where the heck is that israeli spammer kid :s", i'm here, just the drive in my desktop pc died two weeks ago and i can't really do much of anything from my linux box [the specs are really poor].

So anyway you must be wondering what's up with the V5 mod.
Well, i'm starting to see why the other modders have failed in doing this one.

I already have the card, a V5 5500 AGP 3700, modded to a total of 128mb, but i'm hitting a deadlock when it comes to SLI [the v5's most obvious feature].

See, the bios i now have, recognizes this card as a 128meg, [64mb in dxdiag, as opposed to 32mb on a normal v5] and everything *seems* to work properly.
emphesis on *seems*

When I do any kind of 3d in it, for some bloody reason it 'forgets' about the additional ram.
it jumps back to 64mb [32x2] as if the extra ram just isn't there.
BUT, if the second VSA chip is disabled, i get the full 64mb for the first.

This is an oddity that goes beyond my understanding.

Once i get my desktop box back up, i'll continue to do my bios hacks to try and fix this show-stopper. but i think that it's the driver's fault here. not sure.

@paul
yeh it is possible, but you always get the best performance by using identical chips.
cause for example, you can use four samsungs and four hynix, but the samsungs will be 2mhz behind, or won't be able to coop with the timings that the hynix chips can. etc'
just the same as it is with your pc's ram. mixing different sticks from different vendors isn't always a pleasant expirience.

He stated somewhere in the beginning of the post that he got the memory from a Geforce2 Mx.

That was with his Voodoo 4 4500. Those were just 8MB chips he soldered on the free spaces that his card had.

The memory is from two GF4mx 420 cards.
got lucky enough to find two oem cards that had 4 chips on each.

originally, the 5500 had hyundai chips, and now it sports eight samsungs =]
