V-mod Gf2 Mx 400 "ennyah digicolor"

[Dieter@be]

I want to V-mod my gf2mx 400 (ennyah/digicolor).
It has 64MB DDR, 1xVGA, 1xTV-out.

I found these two sites:
http://www.obroa-skai.de/gore/inhalt/howtos/vmod2mx.php
http://www.xbitlabs.com/video/geforce2-overclocking.html
But the problem is, that in both of them, they have a Unisem US1150 voltage regulator on the card, while I have a:

AMS
1503CMA
0036
(That's what is on the chip)

I assume that two totally diffirent voltage regulators work also differently, so the explications aren't valid for my card.

Need help...

Ok, i registered and posted a message...

Btw my AMS chip has 5 pins, the UNISEM has 5 pins, and the AME (the one in the AoA Topic) has only 3!

Hm, that aint gonna work out :(

But at least I found the website of the brand of my chip:
www.allegromicro.com

But the really weird thing is, I cannot find a datasheet of my chip!!

AMS
1503CMA
0036
(That's what is on the chip)

Can you submit a picture of that chip on your card?
I might be able to help you out

I asume a drawing will do the trick...
