X1900XT stock voltages

[Emacs2]

Hi all,

I'm a new ATI user and spent some time experimenting with my new Sapphire X1900XT (256MB) with Revoltec Graphic Freezer Pro attached.
ATT seems to be a very good option to start experimenting ;-)


Currently I have set my card the following way:

2d GPU: 425Mhz @ 1.1V
2d Mem: 531Mhz @ 1.8425V
(this results in about 45 degrees centigrade GPU temp)

3d GPU: 709Mhz @ 1.475V
3d Mem: 792Mhz @ 1.8245V
(this results in a max of 83 degrees centigrade after two hours of Gothic3)

I feel comfortable with the power settings for the GPU but I'm a bit unsure about the memory.
What is the default voltage for the memory on an X1900XT in 3d mode?
I read about 2.0833V but could not confirm this on my card.

Is it true that the original default power settings were:

2d GPU: 1.2 V
2d Ram: 1.8425V

3d GPU: 1.45V
3d Ram: 2.0833V

?

If so, what is a reasonable voltage range for the memory - considering an aircooled (Revoltec GFP) X1900XT ?

Cheers,

Update:

Setting the memory voltage for 3d to 2.0833V I can set the memory to 810Mhz without any problems (no artefacts in the tester, nor in the game).

A very short try to set something to 2.2 V to the memory just resulted in instant freeze of the whole PC.

Cheers,

According to ATI Tray Tools, this is how my voltage situation is:

Stock 2D GPU Voltage - 1.2 V (500 Mhz)
Stock 2D Mem Voltage - 2.0861 V (600 Mhz)

Stock 3D GPU Voltage - 1.450 V (621 Mhz)
Stock 3D Mem Voltage - 2.0861 V (724 Mhz)

I've only personally tried OCing to 700/800 on stock voltages, never going higher, and I haven't come across any artifacting or freezing yet.

EDIT: Sorry, I just noticed you had a 256 MB x1900xt, not 512 mb. So it's likely that my voltages will differ from yours.

[Ray Adams]

There are no 3D voltage for Memory yet. Its always stick at same value in 2d and 3d.

[Emacs2]

Okay, my card (Sapphire X1900XT with 256MB) seems to be different then.

The BIOS voltage for the memory is 1.8425V. Setting the voltage to anything around 2V (using ATT) results in a complete freeze of my system sooner or later (roughly after one or two hours of gaming).

I guess, I'll better stick with the default 1.8425V then...

Your card probably has Samsung's K4J55323QG-BC12 mem modules - they are capable to work at max @800 MHz with 1.8V +/-0.1. X1900XT 512MB cards have different, 1.1ns modules, working with 2.0V +/-0.1

[Laykun]

I can't set the voltages at all with ATT, any idea why?

[Ray Adams]

Explain me more, how you can not set voltage?
