## Description

MEMORY 512MB VALUESELECT VS512MB266, 86SD03

Review: Works great - This memory is priced low and the quality is great. It was a little difficult to install. I had to put the PC on its side and then firmly push in the memory and then make sure the tabs on both sides clicked into place properly. It did seem a little shorter than the original memory, but the specs matched, and the chips looked identical to the original. After boot up the memory showed up and all has been well for months.My apps operate much better with the increased memory.
Review: Works great in my iMac G3 500 - Most resources stated the iMac G3 500Mhz used PC100 ram. I figured PC133 would just train down to 100. Surprisingly MacOS 9.1 (and 10.0) show it running at 133 and it works great. No stability issues. just works. Nice upgrade from 64mb to 1gb.

## Questions & Answers

**Q: Is this high or low density? thanks.**
A: Low Density.

**Q: Does it work on a Powerbook G3?**
A: This memory is not compatible with the Powerbook.  This is desktop memory.  To determine what is needed for your model, we need more information.  Along with the Powerbook G3, we will need to know the processor speed.  For example Powerbook G3 333 or 233 or 500.Thanks,TrishCustomer CareArch Memory

**Q: Does this work with the ibm netvista a22p 2292?**
A: No idea.  You would have to look up the specs for that machine.  You can find them online.  Typically a specific type of RAM and a range of speeds and capacity will work with a given machine.

### ⭐⭐⭐⭐⭐ Worked Great!
*by H***W on February 23, 2012*

I had originally ordered a 256 MB RAM stick from another vendor so I had a total of 512 MB of RAM to install a new OS, but it didn't work so I sent it back. I got this one and it worked perfectly. I was able to reinstall Windows XP Pro SP3 and install the drivers for my wifi PCI card and my 5 input 2.0 USB PCI card. Only issue now is to figure out why the original 256 MB RAM stick is not initialized. That old desktop computer only recognizes the new 512 card, but it is online and fully functional now. I may order another so I have 1 GB of RAM.
