Point of view 7800GT (for Gamer)
 

Voltage of the GPU

• Standard voltage = 1.206v
• IC: (ISL)6563CRZ
• Link to datasheet
• FB = pin6 = 245 ohm => 5k VR between pin6 and GND (pin7)
• Both OVP and OCP present (will look into that, if necessary)

Voltage of the MEMORY

• Standard voltage = 2.06v
• IC: (ISL)6549CBZ
• Link to datasheet
• FB = pin4 = 621 ohm => 5k or 10k VR between pin4 and GND (pin7)
• No OVP, no OCP
• Memory type: Infineon HYB18T256324F-20
• Maximum voltage determined by manufacturer: 2.5V

Voltage measurements



OC results

Not tested.

Isn't standard voltage for the GPU 1.4v ?
I already flashed it to 1.5v.

Hm; must be 2D voltage then?

Yep, that's it.

I guess even 1.6V is possible through bios flashing?

Nope, it was 1.4, max is 1.5.

voltage IC suggests 1.6V through software is possible.

Are these fixed yet ?:)

1 card at 50% ... now I'm out of 10k VR's LOL

Huh ?

Van de eerste kaart heb ik mem gemod, maar ik heb geen 3 10k resistorkes meer. Daar morgen om gaan.

pak er voor mijn kaartjes ook wat gerief mee aub en één a twee temp sensors alst kan, betaal je donderdag of wanneer we de vga's gaan doen voor nations cup...

Prett pleased with the result. I used tape so if you want to sell these cards, you can just remove the VR :)

How good does that hold when actually using the pots?

I strongly recommend holding the pots as well when you turn. I always do it like this and it works perfectly.

To make it harder to detect you might aswell put them VR's on a small Velleman PCB and use long wires. Easier to handle but looks more experimental.

harder to detect?

'easier to adjust', dunno how 'harder to detect' came up there, has nothing to do with it :-/

Are you engaging yourself in criminal activities? :p

I was still being in Fallout 3 sneak mode I guess :)

*Googling Fallout 3*

54K done with 3d01 with CPU at 4.5Ghz on a dirty old sodding winXP with bad drivers and old fart behind the keyboard

With my cards ?
coolio :)

Thanks PJ, can you mail them to me ?
And maybe the 7600Gt's too ?

Expense in on me.
