Leadtek Winfast GT220
 

As almighty JMKe has almost finished his review of this card, he inquired me if I was interested in testing this card under more extreme cooling.

Yes.













From the looks of it, I'll have to look at those two chips.

Datasheet links attached to post.

Unconfirmed voltage modifications; will test them asap.

Without modifications max clocks are:

CORE: 675MHz
Shader: 1450MHz (1500 if mem <900MHz)
MEMORY: 940MHz

01-Nature: 220-ish, without tweaks.

Vmods are confirmed. Now running 1.2V Vgpu and 1.8V Vmem.

CORE: 750MHz (800MHz instant freeze)
Shader: 1600MHz (makes NO difference whatsoever in performance)
MEMORY: 975MHz (1GHz runs, but artifacts)
TEMP: < 70°C (still stock cooling)
01-N: 232FPS (most important clock = memory)

Gonna try more voltage :)

1.35V is a bit too much for this tiny cooler; 1.20V to 1.25V should be doable.

As for memory: doesn't scale past 1.8V that much. 1GHz seems to be the max on air cooling.

u have the zalman cooler on the 9600GT from galaxy try that one on it, it should fit.
just dont lose any mounting bits!

The Galaxy one is awesome (although it's kind of too big - I'll post pics later).

Same voltage as before:

Core (linked) 750 to 800
Mem 955 to 1000
Temp: 80 to 45

u mean the zalman :p?

Yes :p

I believe you still have that more then average good 8400GS too, correct? maybe you should give that one a go too ;)
