I inherited a older Compaq Presario 5070. (Yes I know its an antique, but is free). It has a 300 Mhz AMD K6-2 3DNow CPU installed on the motherboard. I have several faster AMD CPU laying around and was wondering if I can install one of these CPU's in this system without starting a meltdown. The current CPU has 341 pins. Your response and help is appreciated. appreciated.

Hi Watcher,
Before you decide on swapping your CPU, verify the following:

Which processor socket does your motherboard have? To check your processor socket, you may need to open your computer and on the socket you would see the socket name. eg socket A.
Is it compatible with the processors you have at hand?

Thanks for the fast reply and information. I cracked the case and found that its a Socket 7 CPU. So, went to ebay and found the fastest they have availalble (550 mhz). Bought one and awaiting delivery. I think in furture will put new mobo and cpu in case. Thanks again for your assistance. (Now I have 2 AMD 1.3 mhz cpu's.) Any suggestions on a good mobo?

Hi Watcher,

Welcome to PCHF!

Though it's very likely you won't have any problems with the CPU you ordered, you should probably look up some info on the motherboard you have. If you can find the company who made it's name you should also be able to find the model number and you should from there be able to easily find out what the maximum supported CPU clock speed is.

Those AMD Chips sound like early Athlons...not bad CPUs either unless you're bent on running new games. They are probably Socket A. If the above is true on both accounts, you should be fine with an Asus A7N8X-Deluxe (yay it took me a year to remember that model number...it's my curent board lol). It supports down to a 1GHz (I'm presuming that's what you meant by 1.3MHz as Intels earliest chips in 1978 ran at around 4.4 MHz) and you will have plenty of room for expansion (up to the 3200+ Athlon). Also keep in mind that AMDs Chip Naming convention no longer revolves around clock speed but around Terraflops (that's Terra=Trillion Floating Point Operations per Second). However the nomenclature gives a good indication of which Intel chip it's most comparable to.

IE: 3000+ Athlon is equivalent to the 3GHz Pentium 4.
3200+ Athlon " " " " 3.2 GHz "


Hope this was useful info to ya.
