Installed new memory and comp won't boot

post #1 of 6
Thread Starter 
Ok, I just bought 2 refurbished 512MB 3200 memory sitcks (samsung) to go from 1 gig (2 mushkin 3200 512MB sticks) to 2.

My computer was oced at 220 (FSB), and when I installed the 2 sticks my computer wouldnt boot. At first it did but it only wrote a couple of line on the usual black starting screen and stopped. Then I tried again and all I could get is a long beeeeeeeeeeeeeeeeeeep, beeeeeeeeeeeeeeeeeeeeep, beeeeeeeeeeeeeeeeeeeeeeep sound (longer than the usual beep). I even tried to remove the new sticks I installed, same problem!!!! What is going on? Is my computer dead? Because of ram sticks? That I just bought? and that are supposed to be 100% compatible with my mobo?????

Well now I flashed my bios, so I can restart with 200 FSB instead. It worked but I haven't tried to install my new memory again... going now. BUT PLZ TELL ME WHATS GOIN ON!!! IM SCARED!!!!!!!!!!!!!!!!!!!!

I just found that list on my mobo website...
Look at the samsung compatibility.

It says I have to set the CL at 3... with my mushkin sticks it's currently at 2.5... and my samsung are 2.5 native too...

Well, before you panic:
  • Have you tried resetting the CMOS?
  • Using one memory stick only
  • Are you trying to use all 4 sticks at the same time?

i just bought a stick of 512MB for my G3 iMAC and I got the same results...long beep and wouldnt boot...but it worked just fine when I took it off...BUT I bought the stick used and with a "might not work" warning on it from ebay...so I guess what im saying...your "refurbished" ram could be damaged.

I know what the problem is.

I tested every configurations (clearing cmos with the jumper between each).
My new memory works just fine... but as soon as I mix the to kinds (mushkin and samsung), I can't boot.

Even though the new sticks I bought are suppose to be Cl 2.5, they only works at 3...
And my mushkin only works at 2.5.

So when I mix them my bios don't know what timing to put so it just don't boot. Well that's my interpretation... maybe it's something else, you guys tell me.

Y can't my mushkin tolerate 3???? It's higher damnit!! Any idea on what I can do? Can adding voltage helps?

I have no idea why your 2.5 won't run at 3.......but I do know mixing and matching brands is not usually recomended though.......have you put in just the mushkin stick and set it to 3 and it won't boot?

May just want to sell those off and get 2 sticks of some matching sticks......


sorry
