Dimension4700

I have an older single core in the unit and I am running 32 bit software, because that is what the older processor works with. Putting in 4 1 meg strips I come out with 3 Gigs during memtest. Does anyone know of a BIOS fix to get around this, or should I find a compatible Core 2 Duo to make this 64 bit compliant? I appreciate so much having somewhere to discuss and I will share quite a bit whenever possible.

RE: Dimension4700

32 Bit systems are limited to 4gb RAM. However, all computers required some of the 4gb address space to handle things like RAM that needs to have all it's own RAM mapped into the address space of the main memory. This can easily take 0.5-1.0 gb, which is then lost to the system RAM total. Most 64 bit systems have more address space than physical RAM, so operational RAM is not lost. Some older hardware, had only enough address lines on the system board to handle 4gb, so no real advantage.

Dual Core, Core 2 Duo, or Core 2 Quad processors are not supported by the Dimension 4700.

Any Socket LGA775, P-4 processor 520, 530, 540, 550, 560, 570 with HT Technology, will work.

Also the Prescott P4 64-bit 571, 3.80GHz, 800FSB, 1MB, Socket LGA 775, will work.

Prior to installing the processor, you need to upgrade the BIOS to the latest version A10, when support for newer processors was added.
