This result is not very good, because there is some driver issues or incompability with Gigabyte DS4.

More results later.

System:
Gigabyte DS4
E6400 @ 3.4GHz
Teamgroup ram @ 5-6-6-15 (425Mhz)
Driver 91.45

Push it further man! .

I got an MSI 7900GS in my PC (got it off woot), buying a waterblock for it today. Does 500/800 on stock air STABLE no mods, havn't pushed it any further yet. Good luck with yours .

[SF3D]

I will!!

But first, I want to know limits of this card air cooled and without mods/tweaks.

Easy 10K

[NickS]

Very nice. I'm not going to expect 10k because I only have a single cored venice @ 2.5GHz, and I'm too lazy to up it to 2.8GHz for some benching.. but I cant wait to get my card under water.

Great results!

Does the card support HDCP?

[yotomeczek]

What is difference to 7900GT ??

[Starscream]

7900Gt has 24 pipes.
7900GS has 20 pipes.

they got about the same clocks but the GS seems to be some 40 euro cheaper in europe (dunno price diffrence in US).
and last week woot.com had a sale were the GS was like 130/140 dollars orso.

[SF3D]

Great results!

Does the card support HDCP?

It should. Box says so

[Skyline GT-R]

Where to find these cards? They are NOT on any vendors site and I also didn't managed to find a shop that has them for sale... This baby is really what I am looking for for my conroe upgrade!

600/1800:
Mem on this card is very good.

[NickS]

Yep but the memory isn't what is limiting the performance. The core is . Maybe there is a pencil vmod for the core of this card?

I will do 1.3V or 1.4V mod tonight.

Default Vcore is 1.2V

I'm confused by those vmod pix, can someone enlighten me?

[SF3D]

Lower picture : Post 640

red 1.25
yellow 1.30
red + yellow 1.35
Purple 1.40
purple + red 1.45
purple + yellow 1.50
purple + red + yellow 1.55

So all points connected = 1.55V

I just connected D511 (purple) to ground and it give 1.4V
It's easy, trust me

[NickS]

So i just pencil all the red & yellow spots for 1.35?

[SF3D]

You have to connect them totally, so use conductive paint or something similar.

[NickS]

Where can I get a conductive pen?

[SF3D]

This card is unbelievable. Price ~190 € (or lower)

I could test this card in "low end" pc if someone is interested. (DFI ultra-d, AMD 64 3200+ 1GB BH-5)

[su27upgrade]

Great results!

Does the card support HDCP?

generally no

[Fatal1ty]

Any chance of unlocking?

[NickS]

Sadly, no. It's just a 7800GT with a shrunken die.. hence its overclockability and good performance. The 7800GT was and always will be a champ imo, but the 7900GS really tops it for the money.

[Skyline GT-R]

Just ordered an Asus 7900GS for 200€ Can't complain. I'll post my findings when I have my new rig.

Nice! Let us know your experiences when you get that.

I'm still using default cooler with 1.4V. Idle temperature is 55 -->load ~70.

OC: 670 / 1850

Next move: Watercooling and more voltage
