and when i installed rams everything works fine pc turn on rams fits 1 beep sound i now have 2.5gb ram but when i open my computer to check i have 512mb ram. my pc dose not read the 2x1 gb ram i installed why? my pc can hold 2.0V ram (Acer aspire AST180)
Take the old ram out, try the new ramsticks one at a time, see if you boot ok,
if both turn out to be ok to boot with seperately, install them in dual channel config, usually a1+b1, or a2+b2 slotwise will activate that, then post back your progress
p.s. put your 512mb stick in a antistatic bag if you have one, keep it safe from getting fried
I tried putting 1 of them in my pc and start it when i start it it launches the fan and power up but the screen stayed turned off and the pc makes that sound BEEEEEEP (1 sec) BEEEEP (1sec) BEEEEP i think the pc thinks the is no ram installed so pc wont launch. anyway when i put 3 of the ram bar pc launches normally with one beep(means correct) but Crucial Ram test says i only have 512mb so the pc dosent detect the new ram is there any updates i can do for my mobo or anything because my ram bar are supose to work...no?
3 beeps normally indicates a ram issue,
did you try each of the new sticks on their own?
We'll need you to post your exact Mobo model number as well,
Im not sure what you mean by ram bar, but we need to find out if the new ram is defective, one stick obviously is (put that one back in its bag), try the other new stick on its own
ok, I'm running out of ideas lol, cant find your Mobo on the net lol
whats the exact specs of the old ram? and the exact specs of the new please
Its possible there are bios updates out there, but I dont want you getting into that unless absolutely necessary
Thing is there your old ram has different voltage to the new stuff as I read it,
have you altered your ram voltage in bios?
and mixing the two voltages is going to create problems, especially if your bios setting is auto
It wont know which amount to use and I think it will probably default to the lower voltage to be safe, definately dont have the two mixed in your slots man
you remove the 512Mb stick as I originally advised, so you have no ram in there at all then you try one stick of the new ram on its own, then the other stick to ensure both are working ok,
if you are worried about updating the bios yourself, maybe a local pc centre would do it for you cheaply enough.
but if you follow the intstructions from your Mobo's website, you should be fine imo
I think either your Ram is bad, unfortunately it can happen sometimes that both sticks are faulty, or that your Mobo doesn't support it,
Maybe surf through the information about your Mobo on manf's website as to any memory support revisions, that would tell you if its worth updating the bios or not.
no point updating it if theres no difference to the bios (regarding ram in your case)
I'm sorry I havent been able to resolve this man.
