What is the difference between E0 or G0 stepping?




My motherboard is GA-965P-S3 (rev. 3.3)

Does it support 45nm ?

Question:

Overclockers
Intel Core 2 Quad Q9550 LGA775 'Yorkfield' 2.83GHz 12MB-cache (1333FSB) Processor - Retail


Is this the E0 stepping CPU?

I cannot afford to upgrade the motherboard, memory and cpu for i7 setup. I am looking at a long term solution on my current setup.

I brought the q9550 from overclockers.
I am very pleased to say that it is a E0 stepping

I have no overclocking knowledge and managed to reach 3.6 ghz stable with ease. I hope to reach 3.8/4 hopefully.
