We would classify the AD70-SR’s stability as reasonable. We were able to crash the board under extreme circumstances, but in general, no more than is typical of most motherboards on the market. Remember that these are extreme testing conditions. The board is quite capable of sustaining long periods of normal usage without any problems, as are most boards on the market.

	STREAM Memory Bandwidth	Quake 3 Arena (640x480x16)
DFI AD70-SR (KT266A), 266MHz / 266MHz (FSB/Mem)	1024 MB/s	244.6
ECS K7S5A (SiS735), 266MHz / 266MHz (FSB/Mem)	732 MB/s	214.9
ECS K7S5A (SiS735), 266MHz / 133MHz (FSB/Mem)	586 MB/s	199.9
Gigabyte GA-7DX (AMD 760), 266MHz / 266MHz (FSB/Mem)	702 MB/s	206.4
Iwill KA266-R (ALi MAGiK), 266MHz / 266MHz (FSB/Mem)	761 MB/s	208.9

The AD70-SR’s performance is right where we’d expect for a KT266A-based board. As we mentioned about a week ago in our review of Iwill’s XP333-R, stay tuned over the next week or so, as we’ll have a much more detailed look at the performance of modern Athlon chipsets. Suffice it to say the AD70-SR is well within the acceptable performance range for boards of this type.
