#Dell gx620 drivers windows 7 64 bit 64 Bit
Technically it can support 64 bit, but in reality, its a 32 bit CPU that emulates 64 bit (EMT64 Instructions) its like people who call old pentium 4 HT a dual core CPU, but another problem he might face is finding 64 bit drivers for a system that old (yes the pentium D is an old CPU) and unless he wants to run more than 3.25GB if RAM, 32 bit is the way to go, its supported, and will be supported for a long time (atleast in the PC market, Apple killed it with Lion)īut in all reality, if you want to run a 64 bit system, I recommend hitting up eBay for a cheap Core 2 Duo CPU, then a 64 bit O/S might be a little more viable
