Ok was shopping around for a replacement to a celeron 450, noticed some of the lga775 compatible cpu's had contacts, not pins. However, the celeron 450 has pins...how does that work? Doesn't seem logical to me, I have a lga775...never had the cpu just yet but wondering if its possible to upgrade to maybe a core 2 duo 8500 in a Dell 530s. Says on the website anything compatible with lga775 on a g33m02 motherboard. But then again one site says upgradable to 4 gb of ram and another says 8. Confusing times. Need help?

Are you sure its socket 775? Before 775 Celeron and Pentium 4's used socket Pga socket 478. These sockets used pins on the CPU chip similar to AMD's current CPU's. Then they switched to 775 that used PGA with pins on the socket and pads on the CPU chip. Download CPU-z and under the tab see what it says.


Socket Pga 478


Socket 775


Both take a version of Celeron and Pentium 4 but as you can see they are two compleatly different sockets and are not cross compatible.

If the Dell has the G33 chipset it is a socket 775 based board that will support the Intel® Core™ 2 Duo E8500. You are going to want to check with Dell to make sure that their Bios support these processors but the chipset should support it. http://ark.intel.com/products/chipsets/29000

The 530s came with an core2due E5200 and the stock motherbd only supported these cpu's:

Wolfdale Core 2 Duo, E5200, 2.5GHz, 2MB, 65W, M0
Wolfdale Core 2 Duo, E7400, 2.8GHz, 3MB, 65W, R0
Wolfdale Core 2 Duo, E8400, 3.0GHz, 6MB, 1333FSB, 65W, E0
Wolfdale Core 2 Duo, E8500, 3.16GHz, 6MB, 1333FSB, 65W, C0
Wolfdale Core 2 Duo, E8600, 3.33GHz, 6MB, 1333FSB, 65W, E0
(note you may need to update your bios first)

so it doesnt sound like you Dell has the original motherbd. You may need to examine the motherbd for the make and model # of it to determine what it actually supports.

a g33m02 motherbd will only take core2duo or core2quad cpu's (according to Dell) and, fortunately for you, will work with any of them. But the slimlines did not come with that motherbd and you would probably need to upgrade your power supply before running a quad core. (no easy feat for a slimline case)

I've already converted the board to another case and installed another PSU. I suppose I will have to take the CPU out and examine the socket to be sure of what I have since Dell isn't sure what they put in their cases. It's an original board, even the service tag on Dell site confirms that. The pin and contacts dilemma is what was confusing me though. I'll post back later on my findings.
