I just ordered a Q9550, to replace an E6850. I can't afford to switch platforms. I was just wondering if there was that much difference in overclock ability between the C1 and E0 stepping. It's going to be a while before I can afford i7/X58/DDR3. I plan on a moderate overclock for 24/7 use.

You will undoubtedly receive an E0. A lot depends on the VID of the chip. But , on the average, the E0 should be a better overclocker.

When I bought my Q9550, I received a C1 chip. VID was average, but I was still able to get it to run at 3.6 GHz.

Thanks for the reply. This is the system that the community helped me OC about a month and a half ago. Computronix introduced me to the VID with that one. While I'm waiting for the CPU to show up, I'll research it and learn more about it. The only thing I got out of the intro was lower is better. I wasn't sure if that was the high or low range, but I assume that it was the low range, enabling the processor to run at lower voltage and therefore less heat generation. I was torn between a GPU or CPU with my upgrade money. Do you think I made the right decision?

Depends on what you do the most. Gaming? You should've bought a new GPU. Anything else? You made the right choice :p

I spend more time photo editing and modeling, but wanted to see what a quad would do in GTA IV. I found an article on voltage ID and I grasp the basic concept. Where do I find the "average VID" for the Q9550?

I got the Q9550 in and my VID is 1.1000 - 1.3000. Here is a screen shot. Thanks again to all for the assistance and patience.



No stuck sensors, temps moderate. I'm Happy.
