Performance and overclocking

Now on to the testing. I had ATI Tool and Catalyst Control Center open at the same to make sure the temperatures aren’t different. My test system:


AMD64 3200+ Winchester @ 2.4GHz
DFI Lanparty nF4 Ultra-D
1GB Geil PC4000
Seagate 160GB EIDE
Enermax EG425P-VE SFMA

This smokin’ X1900XTX

X1900 XTX Temp Results
	Idle (degrees Celsius)	Load (degrees Celsius)	Delta T (degrees Celsius)
Stock ATI Fan, dynamic speed	48	69 (67 in CCC)	21
Stock ATI Fan, 100% speed	46	65 (63 in CCC)	19
Zalman VF900-Cu 100%	46	60 (58 in CCC)	14

Overclocking

The card reached 711MHz with the Zalman, and had a 2C increase over previous load. With the stock ATI cooler, it reached 708MHz, and had a 2C increase over the stock load temps. So the Zalman VF900 didn't drastically affect the overclocking headroom of the card.
