If the computer boots with both CPUs in but only runs off one you need to set up the OS to use both Winnt has a couple disks to install. Also you have to have one bank of RAM for each CPU.

Microstar....
TWO Slot 1 for Intel Pentium II/III/Celeron Processor. Supports up to 550MHz or faster.
Hope this fits FIRST...
Otherwise.. some words say..
Checking the web site...there shouldn't be any difficulties. You MUST check the state ofBOTH CPU's if they both work one at a time the second thing to keep in mind is that one of your CPU slots may be defective. The second thing to look into is to check if the FLIP CHIP is your problem. Contact Tech support and ask them if they are compatible in a dual CPU system. If all that goes well and you are getting answers that meet your criteria check to see that the REST of the hardware is cool. Start buy removing ALL cards except video card. And also means swap out the video card for a test if it still fails. I hope that your CASE power supply is within standards for the board too. Hope these help.... but, I think it's something to do with your CPU's if everything else is cool. Latez-

I have tested all of your suggestions before posting this problem. but let me focus on my suspect.
PS:I found the bridge to be the problem.

ccbz, Check and make sure that the Voltage Regulator Module (VRM) for the second processor is firmly seated in it's socket. If the mother board does not see the second VRM it will boot up as though there is only one CPU on the motherboard

What operating system are you running? Only Windows NT and Windows 2000 support more than one processor. If you have Windows 95/98 then it will only ever use one processor.

Ahhhh a familiar problem... Same thing as you trying to set up dual flips on a Slot 1 board. Well my slot 1 was a gigabyte GA-6BXd the problems i ran into with this board was the fact that the manufacturer said it would run a 650 when after contacting the shop from which i bought it from said they had had no luck with running more than a 550 on it. After going through every thing i possible setting jumpers switching dip switches I decided to try a pair of 550 p3 flips well guess what the 550's worked "BUT" I had excessive load on CPU2 while CPU1 sat fairly idle. The processors were numbered in sequence so I discounted a matching problem as far as CPUs go so a laid suspect to the Slockets for this problem... Now why I went into this last part is to impart a word of advice: You will want to buy a dual Socket 370 I feel that the slockets are not made to the exacting tollerance needed for dual processing. I suggest going with MicroStars 694D Pro awesome board with lots of features including 4 IDE Channels 2 ultra 33/66 DMA and 2 Ultra 100 DMA with a 133MHz FSB and support for up to a 933 P3 Flip Chip. btw priced nice at 200 dollars or less. I just pluged in the 650 p3 100mhz processors and off I went.

That would be a step to go if i cannot fine the sugested bridge my chips.
