Unlocking a Dell

So a few days ago my friend decided he was going to get rid of his dell and i offered him 50$ for everything besides the speakers, mouse, and keyboard beacuse i already had them all. Now i was wondering if it is even possible to oc a dell. It is a Dell Dimension 2400, so i was wondering how do you unlock a dell.
 
Can't with that motherboard. ;)

The Dell motherboard has to be switched to a s478 motherboard that allows overclocking, otherwise, you cant do much other than change the boot order. :p
 
Yeah i didn't think anything could be done to it :D Oh well im lucky it has an AGP slot, i think ill shove an old 5200 in their and happy new year 8yr old brother. I will have to introduce him to the [H] once he pulls his head out of his ass and stops playing HL2 :p
 
What chip is in that Dell? You might want to do a lil switch with the chip from one of your other rigs, as Dell got the creme of the wafer crop when it came to cpu's . :)
 
yeah, check the cpu

I ordered one of the old 600sc servers with a 2.4 533fsb chip and it turned out to be an SL6RZ that easily hit 3.2ghz in an abit board

The Dimension 2400 doesn't have an AGP slot, just 3 PCI slots (i845GV chipset = Intel Extreme Graphics 1).

The clock generator chip on the 2400 doesn't support 1MHz steps. If you already have a 533MHz FSB processor in that system, forget about overclocking (the clock generator only supports fixed FSB speeds, maximum is 133MHz QDR). There's also no voltage adjustment.

You're not going to have much luck unless you have a really overclockable CPU installed in that system (i.e. NW core P4/Celeron 2GHz) since your only choice is to bump a 400MHz FSB CPU to 533MHz FSB at stock voltage. You can play with VID pins (isolate/short) to bump the voltage, but that's not exactly simple if you have to isolate a pin.

That's actually a good suggestion. The 2400 case has standard micro-ATX mounting points and despite what others continue to say, all Dell Dimensions for several years have used standard ATX 12v PSUs. Plus a new motherboard will have an AGP slot.

I have replaced motherboards in that same case. Here is an Asus Athlon motherboard that I installed in a 2350 case (1 generation older than the 2400, but the exact same case). And yes, the Dell ATX PSU is 100% standard and installed with that motherboard:

I have the case front panel harness pinout (audio, power, led, etc) if you're interested. I figured it out myself. ;)

Actually, you can do a lot with the stock Dell motherboard using WPCREDIT. I have adjusted memory timings, memory refresh, etc using that program and the standard 845 register file. For some things you have to reference the chipset datasheet since the older 845 file doesn't have all the register settings mapped.
