Of course.
The question is does it matter if they are similar memory chips.
And like Vapor says, that's a pretty low OC for such a high rated memory module (but maybe it's just the method). My R9600Pro does 530/360 stable without issue. The main thing is that ATI decided not to give people the same overclocking potential that those of us with the R9600P had. You can get faster memory still from other vendors. Personallly I'm not too impressed, it's not the Fireblade edition or something that would lend to that heritage. Even the BRAVO and Extreme editions out there have much faster memory (2.5ns) which would go much further.
Often it's a SMALL margin, but the BBA model is not a good one to compare to, compare it to the Hercules, ASUS, HIS (<A HREF="http://www.gamersdepot.com/hardware/video_cards/his/9600xt/001.htm" target="_new">reviewed here</A> and <A HREF="http://www.hardavenue.com/reviews/his9600xt1.shtml" target="_new">here</A>). The Sapphire NON-Fireblade edition does not come with Thermal Diodes unlike the ASUS and Hercules boards (along with the ATIs). Not sure how Overdrive works on these non-Fireblade cards without the thermal sensors.
BTW, if you read the article you would be able to decide for yourself if the performance difference mattered to you or not.
