I posted earlier about trying to decide whether to upgrade the memory on
the server, or the cpu
I had a 3.06 GHz hyperthreading cpu and 2 GB of ram
when 30 students would all try and load say, OOwriter, cpu use pegged
and memory usage showed 1.9 out of 2 used. It would be real slow, until
all where in, then settled down slightly. But web pages and something
as silly as tux type would bog the whole system down. I know something
had to be done but could not choose.
We settled on memory, upgrading to 4 GB. Then I got nervous and ordered
a dual cpu board and two Xeon 3.06 cpu's as well.
Then I was frustrated yesterday when the server atx case I planned to
use had the wrong power supply. the ASUS PC-DL Deluxe motherboard I
bought needed a SSI type 24 pin connector, mine was 20 pin.
After some frustrating research I learned what the difference was
between an SSI 24 pin connector and the power supply I had was, then I
bit the bullet and went out and paid 185.00 plus tax for the right power
supply.
Then today I was frustrated again. After plugging in the power supply
and connecting everything, I got nothing but a single loooong beep on
power up. No video at all. after two hours of frustration, I called a
friend for a fresh perspective. He brought over another duelly system.
We tried video card first, known working from his system. Zip. Then we
tried his memory. Voila! My 4 GB Kingston memory was defective!
Sh&&%t! All that wasted time.
Trouble was, my friend only had 2.5 GB of ram for me to try. Everything
is functioning great though, and I didn't have trouble with the new
hardware. Nics had to be configured, thats all
So now, instead of changing two things, cpus and memory, I basically
have a dual cpu machine, and 2.5 GB. I plan to try out the system under
load with the students on Monday, seeing as how I have no choice.
Replacement ram will take at least a week to arrive. By the end of the
day on Monday I will know whether doubling the cpu's solved the entire
issue. If it does, I will get my money back for the ram and leave it at
that. If it helps, but not enough, I will go for the ram to
If anyone is interested I will post results Monday night.
