I recently gave my mom the cool (but old) DG965RY with a standard 3 GHZ Pentium D processor and 4 Gigs of RAM that is capable of running on a 1066 System Bus. It seems a shame for this RAM to be slaved to the 800 MHZ FSB of the Pentium D, but since the DG965RY is so old, I'm having a hard time finding Core 2 processors (on the market) that are officially compatible with it.
One Core 2 Duo processor that I found that looked REALLY good was the Intel Core 2 Duo E7600 Processor BX80571E7600 - 3.06GHz, 3MB Cache, 1066MHz FSB, Wolfdale-3M, Dual-Core, Retail, Socket 775 which is available for sale here: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4629529&CatId=2396
Unfortunately, when I goto http://processormatch.intel.com/CompDB/SearchResult.aspx?Boardname=dg965ry that fastest supported Core 2 I see that is supported for the DG965RY is the E6700 @ 2.66 GHZ.
Should I go ahead and buy the E7600 from TigerDirect and try it on my mom's DG965RY and hope it works anyway or do I need to get on eBay and look for a used E6700?
Note: I know that I can get an i3 and Intel Motherboard for about $200, but then I would have to upgrade my mom's RAM from DDR2 to DDR3 and her DVD-RW from EIDE to SATA thus adding to the i3 upgrade costs. It does seem that 4 Gigs of DDR3 is really cheap right now though...
