could quite understand that question so i will answer the one in the title, i also could be more specific without more in.
right i assume its designed for an intel CPU, this assentialing means that it should in thoery take the brillint core 2 duo chip. find out if it is a p965 or 975 chipset, if it is one of these than you should be ok to upgrade, and trust me its worth it.
Hi Sorry I was a bit vague in the previous post. This is my MOBO;http://www.asrock.com/product/P4%20Combo.htm
has a Socket478 which I am using @ present and LGA775
Supports FSB1066/800/533MHz Prescott/Northwood processor, Intel EM64T-enabled processors and H-T Technology
is Intel 04B/04A processors compatible
Supports DDR400 high performance memory
I have a Celeron 2.4 Ghz with a mixed bag of 256Mb PC2100 & 512Mb PC3200 memory but I will be getting 1Gb of PC3200 when I can afford it
The link above does give supported CPUs but I think for that MOBO it might be out of date.
I suppose the real question is why can I not see any supported CPUs which use 1066FSB or is this just for the Memory, in which case which memory uses it. :?
Sorry it is so longwinded but I don't understand why they have included this in the spec.
Thanks in advance for your help
