Thanks everybody I thought I had done all my homework but it's not working so... I understood it to be 64-bit and expandable to 16 GB RAM. I even looked at my ram and googled the numbers on it and chose what I thought would work. Specifically to Drew1903 and your checklist I contend that originally I did all of your list correctly so I immediately thought something else was wrong. I could just try again but as you said #1 is the important part. I didn't know about the Kingston ram check and will do that this evening. Poking around last night trying to get a better grasp of what was happening I confirmed specs in my properties, checked expand-ability via Crucial, and found an interesting review on amazon.The information is below:
(I have written it out but also have an album of screen shots and pics)
Current working RAM (2 @ 2GB):
2GB 2Rx8 PC3 10600U-9- 10-B0
(Sorry for potato quality in pic)
Also in response to the 64 v 32 when looking at the properties of my computer, they are:
Processor: Intel® Core i5 CPU 650 @ 3.20GHz 3.33GHz
Installed memory (RAM): 4.00 GB (3.87 GB usable)
System type: 64-bit Operating System
Looking to see what I should buy I ran a Crucial scan, they said:
Your HP - Compaq 8100 Elite Buisness PC (CMT)
Maximum memory : 16384MB
Slots:4 (2 banks of 2)
(I realize I left out buisness PC in the name of my pc earlier [though I didn't actually know that]. Is this why you found conflicting 64 v 32-bit info?)
4GB DDR3 PC3-12800 Unbuffered NON ECC 1.5V 512Meg x 64
(How close is that to what I bought? I'm fine buying this if it works)
Also looking back at Amazon I noticed a response to a review. It was from a Kingston rep stating:
"Some DDR3 systems that are three or more years old cannot communicate with high density 4GB memory modules properly."
(The pic of this is small, sorry, but could this be a factor?)
Thanks again for your assistance. I will be looking at this post a little bit this evening but will be out of town over the weekend. Meaning I might not get back to you until after the weekend.
