Title: voodoo5 vmod
Post by m14radu on 04.08.07 at 10:08:32
found this link:

http://overclocking.myslenka.net/v5mod/

can somebody translate this ? ( it's slovakisch )

Until now i found more Vmod schematics..witch one is the best ?
Did somebody did such a vmod ?
I still miss a "do it your self " guide for this mod !

There are other online translators too.
If you type 'online translator slovakisch' in Google, you're bound to get results.

its czech.I can translate it (I'm from slovakia).I would do it sooner,but  I have somehow missed this thread..here goes:

on this picture I have marked the SMD resistor right next to switch voltage regulator on the card (LTC2909 if I'm not mistaken, its the one with many pins).

this resistor needs to be unsoldered and on those two contact fields that are left after the removal, you need to solder a cable with 2k resistor and potentiometer with value of 5k in serial connection.a precise xxx would be even better (here is where I fail miserably because I have no idea what part he means.xxx=viceotackovy trimr,I think it should be an electronic part of some sort that allows for voltage regulation,probably by turnig some small wheel,viceotackovy=something that can turn around,trimr=trimmer? guys skilled in electronics will probably know).

thats all. you set the voltage with the trimmer, the smaller the value, the higher the voltage.this config changes the voltage from default (3V) to approx. 4,2V.

After reading about this mod, there seems that the voodoo5 modded cards are more stable and can be overclocked better even with 6ns memories.
200 Mhz speeds are no fantasy anymore.

By reading an article about an geforce card, also with 6ns, i was amazed to hear that the card goes 210-215Mhz with the same memory as our voodoos.
The core voltage seems to be to low on voodoo5.

So that the Key to the quicker voodoo ever is a quick memory together with a volt mod.

User ALT-F13 already swap the slow memory with a quicker memory on his voodoo5 card.
Unfortunately there is no feedback about the card behaviour....

on a geforce you can run asyncon core/ memory clocks
on a voodoo not

there's a bois that seperates ram and vsa's isnt there? i'm pretty sure there is :-/

there is afaik no bios witch separates the VSA and Memory clock.
The idea of desyncronising both components is not bad at all but i think imposible because of the card layout.
It's not related to the software/bios but to the card itself.
Does somebody know more detail about the clock generator that is buid on the card ?
How it's working and so on ?

:o

@exxe: i don't see a problem; in order to overclock the card to 210 Mhz, like the geforce example, there is no importance if the mem and VSA are sync or desync...... please explain. Maybe i'm wrong. ::)

i'm sry then i thought i read someone made a bios that did that but ram was too slow to make a diff, guess ur right cause i cant find anything on it, getting old and feeble :'(
