I'm sporting a 3 year old Intel Desktop Board D975XBX2 Extreme Series mainboard (2 or 3 years not exactly sure)
Anyway, according to the manual my mainboard can support a LGA775 with a 1066/800 MHz FSB. I currently have a Intel Core 2 Duo 4300 1.8ghz processor. I'm looking to upgrade to a Intel Core 2 Quad Q8300 Yorkfield 2.5GHz Quad-Core Processor seen here:
According to the specs on the processor it uses a 1333 MHz FSB. My mainboard only supports 1066 MHz. My question is will this processor work at all on my mainboard? If it does what's the drawback? Can is damage my mainboard or other hardware?
My second question:
On the other side, I could get this Intel Pentium E6600 Wolfdale 3.06GHz Dual Core processor for $50 less.
The Q8300 yorkfield will not work the only quads that will work is the Q6xxx which you will only find used but they do go for around $100 and are fairly good processors and will be a giant leap in performance compared to the 4300.
The E6600 wolfdale will not work the older E6600 conroes will. The wolfdales are 45nm and your board will not support it.
The L2 cache means nothing in the compatibility aspect.
No 1333mhz processor will work in that board nor will 45 nm processors work.
If you notice on there support page the E6600 listed is the 2.4ghz model which is the old core 2 duo conroe.
