ACP-EP Memory 512MB PC133 168-PIN SDRAM DIMM (MAC and PC)

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.

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.

I have a mac G4 450MHz. I was reading and downloading some patches to bring it up to 10.5. the only minimum system requirement I couldn't bypass was 512Mb of RAM. I had 445Mb (I was a little under). I was reading some reviews on some other people's experience with this ram on there mac's. To be clear, PC 133MHz is fully backward compatible with PC 100MHz. I read many form's from Apple.com and many others form lowendmac.com. I couldn't see the harm in ordering $30 worth of ram just to return it if not working. Well it works. Currently I am installing an upgrade for mac 10.4.11 to 10.5.X. Working very well. Couldn't be happier with the end result. Just to be clear this does work with a Blue/Silver G4 (Apple Power Macintosh G4 450 (AGP)

I was skeptical because they blank out the labels on the memory IC's, but it passed all tests so far.

I was helping a friend with their Gateway computer. I already had several of these memory PC-133 memory cards but they were not working in the Gateway computer. The Gateway support was worthless since the computer was 10 years old but when I inquired about the clocking specs on the device sold by this Amazon vendor and gave them my Gateway model number, they were able to match me up with the correct memory card. The price was very decent. The price on this new card was less than what I was seeing advertised for a used memory card on Craigslist.

Ok the product states that this memory is compatiable with mac, not! I tried to install on my G4 quicksilver and it simply did not work. I emailed the store and was accused of frying the memory. No way because the memory stick worked in my other pc. The store refused to take the memory back. In addition the memory was sent wrapped in my paper invoice. What's up with that. No static packaging. I will never buy for this store again.

The two sims that were sent do not work or are seen as readable on a G4 PowerPC mac

I mentioned to our tech guy at work that I couldn't watch Youtube videos on my old Imac Indigo 500 MHz G3. He said to add more RAM. I thought it came with plenty until I checked and I only had 256 Mb. I replaced the 2 128 Mb DIMM with 2 ACP-EP 512 Mb PC133 168-PIN SDRAM DIMMs. It took a few minutes to snap them in and now it's like I have a new computer for twenty bucks. Now I can watch online videos (I have DSL) and my computer is 4 times faster.
