Hello everyone,

I have a computer with Celeron 1GHz processor, 128 MB SD-RAM, Mercury 810 series motherboard. Recently I have installed an additional 128 RAM with same specification of my previous RAM (133 MHz, Hyundai, SD-RAM), but after that my system became very slow while booting, particularly Fedora core 5 while starting UDEV. It(UDEV) just always failed to start and gives a message that it will continue in the backgroud. When I run my system on single 128 MB RAM (any one of them on any empty slot), it works fine. But when I install both my RAMs, it just slow down my PC. Can anyone suggest what is the real problem and also possible solutions.

Thanks in advance...and sorry for my poor English...

As i am new to Linux, please try to post a detailed answer for me. Thanks once again...

Did you check for anything in the BIOS of your computer? There may be something in there related RAM.

Thanks for your quick response Samoth,

I have checked my BIOS and there is nothing which can be a cause for this slow down...

I have fixed the problem with a little GRUB tweak...Here is how...
I just added mem=224 to the kernel line of my grub.conf file...

root (hd1,4)
kernel /vmlinuz-2.6.15-1.2054_FC5 ro root=LABEL=/ rhgb quiet mem=224M
initrd /initrd-2.6.15-1.2054_FC5.img

and that's solved my problem. Now my system is as fast as before.

That's interesting Subrata, thanks for posting your fix.
2 questions thou.

I'm wondering if your bios is seeing the extra 128, Does "post" test the correct amount of memory?

Shouldn't it be 256 not 224?

Hi decrepit,
Sorry to be so late. I am away for some days. The answer to your question is "YES". POST is showing correct amount of memory installed(i.e. 256MB). And now I changed 224 to 244, and it is working fine.
