question about memory for my HP Pavillion 7920?

Question

I have an hp pavillion 7920. It is a 900 megahertz Intel Celeron processor but it runs really slow. It currently has 2 strips of sdram 128megs memory. I decided to try to upgrade the memory. The motherboard is a Trigem Computer, Inc. Cognac board with two memory slots. The manual specs say that it has a max memory upgrade of 512, pc100 strips, divided between the two slots. I went out and bought two strips of pc100, 256 meg sdram strips, put them in the computer and it didnt work. So, I examined the strips that I took out of the computer and they are pc133. The manual says the motherboard needs pc100. I dont understand why the pc100 strips I bought dont work, but the system is running on pc133. I am running windows xp pro operating system, and I just want to get my system to run faster. the current 256 megs of ram just dont get the job done. any advice? thanks everyone

Answer 1

Well the reason in a nutshell is this.
PC-100 Ram was changed to upgrade to PC-133. During that transition period many computers made changes in there motherboards to accept the 133 Ram but rather then to change there tech spec's and re-write there Phamplets they just sold there computers. So they upgraded there computers and didn't change there paperwork to show these changes.
So you need to take back the Ram you bought and exchange the 100 for 133 and you'll be set.
One last note You will also find that using Crucial Ram rather then cheaper Ram you will not only have better performance but they stand behind there Ram.
Good Luck
