anybody know what the maximum my mobo would support, in the GX240? what CPU? i was told 2.4GHZ, 2.8GHZ, and 2.2, and i dont wanna buy a CPU and not have it work, soo hopefully someone could help me, thanksss...

Dell OptiPlex GX240 (1.5GHz - 2.0GHZ)

I would say 2.0ghz.

[pugmug]

P4,2.6 GHz,512 L2 cache,400fsb cpu is the best that GX240 will take as you can read here. http://support.dell.com/support/edoc...cs.htm#1106346 this is the correct cpu. http://www.starmicro.net/detail.aspx?ID=115

Strange they only sell them up to the 2.0 cpu level when the boards can support up to 2.6. I'll never understand computer mfgrs.

[gmcsierra99]

ok, thanks guyss...

It'll take up to 2.8GHz actually, though pugmug has the rest right. Dell's online manuals aren't always accurate or updated. The Dimension 4300 manual lists it's memory maximum as 512MB and it's really 1024MB.

[gmcsierra99]

it would take 2.8? and mine can go up 2 1024 also...

[Raccoon_Guy]

As long as the FSB is 400 and it's got 512k cache (i.e., no Prescotts), yes, it'll work.

[gmcsierra99]

i just think the FSB has 2 be 400MHZ, dont think the cache matters, think my original was like 256K, and my current is 128K, and it works fine...

can i upgrade 2 anything? like 3.2GHZ? or just up 2 2.8?

and the current cpu is a Willamette, has 2 be a Willamette?

[Raccoon_Guy]

About the cache, 512 is the max, but lower will work too. It's just the Prescotts that won't (1024k or 2048k cache).

2.8GHz is the limit, but that's also only becuase you won't find anything higher. There's a rumored 3.0GHz 400FSB, but I've never heard of it, and IF there's one, you won't find it (the 2.8 will be rare enough).

The core can be either Williamette or Northwood, but Williamette stopped at 2GHz and the Northwood is better.

In short, your first statement was correct. Anything you find with a 400MHz FSB will do. Northwood, 2.8GHz, 512k, 400FSB will be the best.

[titanium_soul]

yes there is a 3.0ghz northwood 512 kb with 400 mhz fsb but its rare look on ebay

[gmcsierra99]

ok, thanks, is willamette better than a nothwood?

and i was gonna on ebay anyway lol...

[Raccoon_Guy]

Northwood is better. Williamettes only go up to 2.0GHz (or 1.9GHz, I can't remember offhand), so what you find will likely be Northwood.

[gmcsierra99]

yeahh, i searched 4 3.0, theres 1 in the US, 4 $65...

probrably 2.0, my current is a willamette, 1.8...

[gmcsierra99]

and i dont think i can use a 3.0, cause their FSB's are 800MHZ...
