GTX 480 hardware vmods
 

:) Do anybody need?

No, i dont have these, but it's not much hard to discover.
It's easy if you have card. I dont :D

So if enough people want that, we make it remotely :D (I mean smoking out brandnew card :D)

All I need is voulonteers, with good digital camera for macro shots, GTX480 card and good DMM, able to do basic measurements.

Let me know what info you need, full macro shots incoming in a few minutes :thumbsup:

If these two don't get the job done, there appears to be another one on the front, would need to pull the heatsink to confirm though.

NapalmV5 from XS already done some :D

TiN,

What are your feelings on these caps for LN2 on the 480?

16v electrolytics are big

use 6.3v rated caps...

IDK man... usually when 16v caps are used they are on a 12v circuit.... 6.3v caps shouldn't work for that...

Not bad caps, but Sanyo OSCONs better :P (Violet can / marking)

Use 6.3V or 4V rated caps for Vout lines (core/memory both).
16V rated for +12V input caps

Remember : better to use two smaller caps together soldered , than one big. ESR,current with two capacitors (or more) will be better. Do not forget to put lots of ceramic capacitors. I sometimes use tantalum too, but must be careful with them, if you use them wrong polarity/overvoltage (Tantalum caps have PLUS marked, in contra from MINUS marked on regular can caps) they will burn your PCB to HOLES.

UPD: Evil :-P smile is here :D

most high end power supplies have already very good ripple suppression...on the 12v rail

cap mods on videocards are for v_core and v_ram

I have a few OS-Con's but no 16v ones. :thumbdown:
Attachment 2326

those look like 4v...

it should work for vcore and vmem....
