Hello, I have an old ASROCK 775 dualvsta and I am looking to replace the CPU. A new PC is not in the budget but want to speed it up. Currently only have a P4. I flashed it with the pctreiber Bios 3.19a. The site says it "Add support for E-0/R-0 Wolfdale CPU (Pentium DualCore E6300/E7600 supported!)" Does this mean any e series wolfdale core or just 6300/7600. I found a good deal on a 5700 and 6600.
