Need some mobo help

Alright im fairly experienced with computers but this has me stumped, i put together a computer i had laying around to put in the family room of my house so they will stay off mine, i have a Gigabyte GA-7VTXE and i had a amd 2500 cpu, amd 2000 cpu, and a amd 1700 cpu, ive tried all three they work in the motherboard it runs but it doesnt recognize them for what they are, i put the 1700 in and it runs at 1 ghz, which is suppose to be around 1.5, the 2000 ran at 1.2 ghz which is suppose to be like 1.7 ghz, and the 2500 ran at 1.25 ghz, which i believe is suppose to be 1.9ghz, here is the cpu compatibility list for that mobo

ive went through updated the bios and still no change, id just buy a new mobo but i really dont wanna spend money, if ne 1 could help me out it would be appreciated thx..
 
First you have a need for a Welcome to the Computer Forum! http://www.computerforum.com/70672-official-welcome-thread.html Please remember to review the http://www.computerforum.com/52038-forum-rules.html

The fastest memory supported on that model board is also the front side bus explaining why the 2500+ is seen at a lower speed. That model runs on boards with a 333mhz fsb! When you run a cpu on a lower fsb it will appear as a lower model. The PC1700 memory you are using is your problem there! You will need the 266mhz PC2100 memory to see the correct speed for the Atholon 1700+ and 2000+ models. The 2500+ will still remaiin seen as one of the older slower speed model cpus.
 
oops thx for the welcome srry if i didnt clearly state that im runnin 768MB of pc2100 memory it shows in the bios the memory runnin at 266, the cpus im trying are AmD 1700, 2000, and 2500 from my above post neither of the cpus are runnin what they should be if that clears ne thing up, if need more info i have lavalys everest home edition i can get specs.. thx again
 
yea it does it with all 3 processors and the ram im usin and the cpu came out of another computer that was runnin at the speed its suppose to.. so it has to be a mobo issue
 
The thing to go by now is what is seen on the post screen. When you start it up you can even press the pause key if you have to see what it shows for the cpu you have in at the time. While the 2500+ may run on the board it was meant for a board with at least a 333mhz fsb. If you are seeing the 1700+ as a lower model there and not going by Everest then you would have the problem pinned down. The last thing to do is go into the bios itself to see where the memory/fsb setting is at. If it shows less then 133mhz bring it upto that and try the 2000+.
 
k, i rebooted ram was set to 200, i bumped up to 266, still no change so i manually oc'ed it.. i guess il just oc the cpus..
 
I don't think that would be the best idea there if the board is seeing a problem. Once you start ocing an older cpu you have add that extra cooling as well. If you push that too far you won't have a board too work with. It could be the bios itself that's foobar?
 
One thing that might give you some idea of why this is being seen is to simply clear the cmos. That will restore the factory defaults or should unless the bios has lost programming. You could try reflashing it with the latest and most likely last version to see if that corrects this. It's still a long shot if something on the board is now going.
 
Basically, what is happening is the processor needs a higher FSB than the motherboard is giving it. You pay for the multiplier on the CPU, and if the FSB is lower than it should be, the CPU speed will be lower.

You've tried overclocking it. If the motherboard can handle it, keep raising the FSB until it isn't stable, then back it down a bit. You might be able to get it somewhat close to the speed you need (around 266Mhz).
 
The specifications put that board at the 266mhz max for the fsb. It runs DDR266 PC2100 memory where the 1700+ and 2000+ are supported. The Barton cored 2500+ on the other is common for the 333mhz fsb and PC2700 memory. On a faster board those could oc right out to the XP3400+ speed of 2.3ghz. The condition of the board seeing the 1700+ at 1ghz with 266mhz memory? That bugs me there. If anything that one should able to be seen and run higher if it can be oced. The board's condition for this?

It sounds like your FSB might be set to manual instead of auto in the bios, the 1700 and 2000 should run fine on that board with the right FSB settings.

Nothing can be overlooked there. I doubt all three cpus there overheated and saw what was seen on the old build where the XP3200+ simply won't run at 400mhz(200x2) but runs fine at the 333mhz(166x2) setting in the bios. The cpu there simply cooked and refused to run at the normal stock speed.

If the bios programming lost some information and somehow reverted to manual or you were trying to oc at one point and simply forgot to set that back to auto a few things could be explained fast. A bios on the way out or weak CR2032 Lithium battery on the board? When you go back into the bios look around through the different sections like the advanced chipset to see if there menus showing manual options rather then seeing "auto" or yes on them. The yes setting would be for things like plug'n'play enabled, OS2 support, etc..
 
One or two things are still left to try there. 1) clearing the cmos by removing the battery and moving the jumper back and forth about 30 seconds later. 2) Downloading a fresh copy of the last bios version available for a reflash of that in case the current was some how corrupted and seeing information lost. I doubt all three cpus saw what was seen here from overheating. These would be the last chance before assuming the board's bios eprom was...?
