I put in a new mb Gigabyte GA-M56S-S3. I used the ram i took from the old board which worked perfectly. G-SKILL PC2-6400 4 sticks of 1 gig ddr2.
I put 1 slab in slot 1 another in slot 3 and the bios boots ok.
I put another slab in slot 2 and the last in slot 4 and the bios does not boot no beeps nothing.
I take out 2 and 4 and it boots again. I notice on the screen it says single channel not dual .
Either the mb is bad out of the box or it is a bios setting i cant find to enable dual channell.
I am out of ideas

Normal operating temperature for electronics is 400 deg. Use of silver solder is common. However, MB fixes are rare these days..but given the nature of your board I understand your desire to fix it. Dual boards are not cheap - especially when Tyan had the mrkt tied up. There is a good source for older high end equipment I have used....www.compuvest.com. good luck!
Using the manual for the Gigabyte GA-945P-S3 MB.
Go to page 71 & you'll see bios beep codes for your board:
AWARD BIOS Beep Codes
1 short: System boots successfully
2 short: CMOS setting error
1 long 1 short: DRAM or M/B error
1 long 2 short: Monitor or display card error
1 long 3 short: Keyboard error
1 long 9 short: BIOS ROM error
Continuous long beeps: DRAM error
Continuous short beeps: Power error
As you can see there isn't a code for three short beeps.
When you boot your system try to pause your boot up screen. See if the bios is reporting the correct total of memory in your system.
Bios codes from the link below.
3 beeps for the AMI bios code reports Base 64K RAM failure. You can test your memory. Go to memtest.org Scroll down the site to just under the three screen shots. Download Memtest86+ V2.11
You have a choice in making a bootable floppy disk or a bootable CD-ROM disk. Once completed you boot your system to the testing program. Memtest will check your system memory.
This should help.
