SOYO SY-P4I875P DRAGON 2 V1.0 User Manual page 126

During Boot-up, my computer says CMOS memory Checksum error.
What is the problem? This error occurs if you:
1. Clear CMOS memory.
2. Redo your CMOS setup settings. If your battery is empty the error
will occur more frequently. You will need to replace the battery in
this case. If the problem persists, re-flash the BIOS. If all fails your
BIOS chip is failing and needs to be replaced.
3. Change the CMOS battery.
4. Re-flash BIOS.
5. The BIOS chip might be failing.
Stability Issues
My system intermittently locks up, very unstable.
1. Check the CPU Temp, it might be overheating. Change the CPU
FAN. (Check in the health monitor setup menu what your CPU
temperature is)
2. Do not overclock your CPU
3. Check the specification of the memory module; maybe the M/B
does not support it.
4. Go to BIOS setup and load fail-safe settings. Please check if the
system performance in the BIOS setup is set to Turbo/Maximum.
Set it to normal if so.
5. Check the website for latest BIOS update.
6. Check the website for FAQ's regarding instability issues.
7. Change the memory module or CPU, they might be defective.
8. The power supply might not have enough wattage to support all the
peripherals. If your system has other peripherals connected, like
CD-RW, extra HDD, etc. disconnect them. And see if the problem is
gone then.
9. Install Intel Inf driver.
10. Check if your mainboard is shorting out against the case.
11. Check if your memory module timings set in CMOS setup are
supported by your memory module.
