Point of view 7800GT (for Gamer)
 
3 Attachment(s)
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

OC results

Not tested.

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

Massman 15th November 2009 16:54
Hm; must be 2D voltage then?

Gamer 15th November 2009 19:58
Yep, that's it.

Massman 15th November 2009 21:08
I guess even 1.6V is possible through bios flashing?

Gamer 15th November 2009 21:29
Nope, it was 1.4, max is 1.5.

Massman 15th November 2009 21:57
voltage IC suggests 1.6V through software is possible.

Gamer 7th December 2009 18:51
Are these fixed yet ?:)

Massman 13th December 2009 20:45
1 card at 50% ... now I'm out of 10k VR's LOL

Gamer 13th December 2009 21:04
Huh ?
