My pc is custom built. OS is windows 7 ultimate.Asrock mother board A770DE+. Chipset-AMD rd770.Processor-Amd sempron [emailprotected] is 2048 mb.Bios-american megatrends inc. Version P1.70 I recently added 1 more stick of ram.My problem is-The computer will only boot up if the dip switch is set at position 2-3 (clear cmos). I TRIED to clear the settings by removing the battery,repositioning the dip switch to NormalPosition (1-2). When I do this the system will not boot. I have read all of the Info. that I can find on this site but haven't seen my problem. The PC seems to run fine, even though I believe the dip switch setting is incorrect. Can someone help me out? Thank You PS. The bios screen seems to be set OK. Loaded defaultsWrong RAM...or mis-matched...
Check the online scanner at Crucial.comThank you for responding to my problem. One stick is DDR PC2-5300 the other is DDR PC2-6400. I didn't know if it mattered. Both sticks are compatable with this PC. I will remove one stick, and reboot. Thanks again!I removed i stick of memory,and tried to boot. could not boot in normal position. I tried the other stick of memory , tried to boot- will not with switch in normsl position(1-2). I removed the battery each time for a while but the computer refuses to boot with the dip switch set to normal. The computer will boot with either stick of memory or both sticks of memory when the dip switch is set at position (2-3) clear cmos. I am having no issues during use or at boot.No error messages. Does any one have an idea ? Are you certain that is the clear CMOS setting? CLRCMOS1 ALLOWS you to clear the data in CMOS. The data in CMOS includes
system setup information such as system password, DATE, time, and system
setup parameters. To clear and reset the system parameters to default setup,
please turn off the computer and unplug the power cord from the power
supply. After waiting for 15 seconds, use a jumper cap to short pin2 and pin3
on CLRCMOS1 for 5 seconds. However, please do not clear the CMOS right
after you update the BIOS. If you need to clear the CMOS when you just finish
updating the BIOS, you must boot up the system FIRST, and then shut it down
before you do the clear-CMOS action.
ftp://174.142.97.10/manual/A770DE+.pdfThanks.-I went to ASrocks support site and got the manual. It is the cmos reset switch.Setting at normal,(covering pins 1 and2) the computer will not boot.Thanks all! Today I revisited the instructions about resetting cmos. where it SAYS (clrcmos1), I mistakenly thought that the (1) after clrcmos1 refered to pin 1. It is not. That would be pin 3. I refered back to the picture in the manual. My mistake!! I was worried about nothing. Thanks Raptor! I went back and looked at the diagram. Where it says CLRCMOS1, I thought the 1 was refering to pin #1. It is not,that would be pin#3 My stupid mistake.Thankfully I didn't damage anything. I will pay a little more attention to diagrams from now on.No problem, come back any time.Diagram on p.10 is pretty good, all pin1's are noted.
