What cpu can I upgrade to using my K7SOM+ motherboard? curently using AMD Athlon 1800.

Unfortunately I think the Athlon XP is a 462 pin package and the MS8147C+ has a SocketA/Socket 462 socket for the CPU. The Athlon 64 3800+ is a 940 pin package and requires a AM2 socket, so this CPU will not physically fit.

Hello here is the homepage:

And the + versions:

I would say no because the cpu does not exist anymore.

The only thing you can upgrade is the harddrive and the ram module.

The mainboard uses SDram and DDR ram in there own seperate block.
Sdram is hard to find and expensive.
DDRram can still be bought.

The specifications:

Hope this was helpfull

Click on the CPU tab.

(Features / Specification / Download / Support / FAQ / CPU / etc)

Will support Up To an AMD Athlon XP 2600+,

http://en.wikipedia.org/wiki/List_of_AMD_Athlon_XP_microprocessors

Maximum Front Side Bus support is 266Megahertz.
(Max FSB = 266MHz)

(Motherboard manual states 133MHz.
Note that AMD processors are 'Double-pumped'.
This = 266MHz )

Supports AMD Athlon, AMD Athlon XP, and AMD Duron, processors.

Note in the CPU Support chart where it states -
Socket 462 > AMD Athlon XP > 2600+ (.13u)
The .13u stands for 130nm core architecture technology.

(nm = NanoMeter.
1 Billionth of a Meter )

NOTE*
For the Socket 462 (Socket A) processors, the AMD Athlon XP models are the top of the line.

'Sempy', or Sempron processors are at the bottom.
Low L2 processor memory cache compared to Athlon XP or Duron models.

There are several versions of the K78S5A. The following answer applies only to v.3.x.
CPU: AMD Duron 200Mhz FSB CPU - 950 AMD Duron 266Mhz FSB CPU - 1800
AMD Morgan 200Mhz FSB CPU - 1.3G
AMD Athlon 200Mhz FSB CPU - 1.4G AMD Athlon 266Mhz FSB CPU - 1.4G
AMD Palomino 266Mhz FSB CPU - 1.2G
AMD Athlon XP (0.18u) 266Mhz FSB CPU - 2100+ AMD Athlon XP (0.13u) 266Mhz FSB CPU - 2600+
I hope that helps! Good luck.

AMD Duron (Highest being the Duron 1800 running at 1.8GHz)
AMD Athlon XP (Highest being the Athlon XP 3200+ running at 2.3GHz)
AMD Athlon MP (Highest being the Athlon MP 2800+ running at 2.1GHz)
AMD Sempron (Highest being the Sempron 3300+ running at 2.2GHz)

i could only fins thease specs for you

AMD Athlon up to 2400+
AMD Athlon XP up to 2600+
AMD Duron up to 1.8GHz

Socket A/462 can take any AMD K7 family processor. The fastest you could get would be the Athlon XP 3200 I believe, but that could also include the Athlon 1400 and the Duron 1800. So it looks like you can make a significant upgrade of yhe processor.

Here is the list of compatible processors for your motherboard:

AMD Athlon 650, 700, 750, 800, 850, 900, 950, 1.0G, 1.1G, 1.2G, 1.3G, 1.33G, 1.4G (Thunderbird)
AMD Athlon MP 1.0G, 1.2G, 1500+, 1600+, 1800+, 1900+, 2000+, 2100+ (Palomino)
AMD Athlon MP 2000+, 2200+, 2400+, 2600+ (Thoroughbred)
AMD Athlon MP 2800+ (Barton)
AMD Athlon XP 1500+, 1600+, 1700+, 1800+, 1900+, 2000+, 2100+ (Palomino)
AMD Athlon XP 1600+, 1700+, 1800+, 1900+, 2000+, 2100+, 2200+, 2400+, 2600+, 2700+, 2800+ (Thoroughbred)

AMD Sempron 2200+, 2400+, 2500+, 2600+, 2800+ (Thorton)
AMD Sempron 3000+ (Barton)
AMD Duron 600, 650, 700, 750, 800, 850, 900, 950 (Spitfire)
AMD Duron 1.0G, 1.1G, 1.2G, 1.3G (Morgan)
AMD Duron 1.4G, 1.6G, 1.8G (Applebred)
You motherboard uses a "Socket A" CPU and therefore has limits to how high you can go.. I would recommend the XP 2200 or 2400+ as a good choice, but you can make your own choice.

Depends on which AMD processor you would use. If Duron you could go to 1.8Ghz. If you use Athlon XP you could go to 3200+. Athlon MP 2.1Ghz and regular Athlon 1.4Ghz.
