SLI GPU Core Clocks

Hello,

I have two 9800GTs in my system in SLI.

The first graphics card I have is the;

eVGA 9800GT
Core clock 555 MHz
Shader Clock 1350 MHz
Memory Clock 900 MHz

As for the second one;
Gigabyte 9800GT
Core Clock 738 MHz
Shader Clock 1836
Memory Clock 900 MHz

Okay so my question is, is the difference in core clock speeds going to affect me in any way? Also should I run the faster or slower one as the first card(if it even matters that is)?

Thanks in advance.

Why is the clock different? Is the card idling?

When I was running two different 7900GT's I always had better results with the faster one in the primary slot.

Sorry for the late reply guys...

@shadow187 - The clocks are different because they are different brands, and one comes oc'd out-of-the-box.

@mousemonkey - Thanks for the reply. I will try flipping them and see if I see any improvement.

Is the EVGA an 'eco' version? I thought the minimum core clock on all 8800GT/9800GTs was 600mhz. Perhaps your one is downclocking?
Download EVGA Precision and you should be able to set them both so they run at the same clocks, you may have to choose some middle ground if the lower clocked one can't keep up with the Gigabyte clocks, but you will end up with better performance as they usually both end up running at whatever the slowest card's clocks are. I run my 8800GTs at 675/950 for everyday.
