PowerMac G4 Quicksilver RAM Issues

Hello,

I'm having troubles with some ram that I bought off ebay...

I have a 933 mghz G4 quicksilver and from what I understood on various ram sellers website the ram that I purchased would work but it doesn't.

Here are the specs of the RAM that I bought:

Size & Bit 64 Bits
Data Rate 133 Mbps
Bus Frequency
Backward Compactible 100/133 MHz
Package Type TSOP-II
PC133
Densities 512MB
Voltage 3.3V
RAM technology SDRAM
Form Factor DIMM 168-pin
Low Density YES

3.3 Volts, unbuffered, Non-ECC
512MB PC133 LOW DENSITY SDRAM MODULE



The actual ram stick has only 8 small black chips on it

So where did I go wrong?

Thanks for all your help!

That is interesting because it's Low Density you need on the older machines like the Quicksilver. If it used High Density chips then it would not work at all.

What happens when you install that new RAM? Does not show at all?

Here are the specs on your Quicksilver and the RAM specs do match up.

Power Mac G4/800, 933, 1 GHz (Quicksilver 2002)

The Quicksilver is a pain in the behind when it comes to RAM.

A lot of 512Mb sticks won't work, even when they should in theory.

Stick 3x 256Mb sticks in it - it's just easier.

When I install the ram, the mac doesn't recognize it with my other 512 stick.

If I install it without my other stick I get one beep and it doesn't boot.

Obviously it is not Mac compatible memory.

Here is what OWC at Find the latest Performance Upgrades, Firewire and USB Hard Drives, SATA, Memory, Laptop Battery, and more at OWC specify so check it out against this:-

512MB PC133 CL3 3-2-2/PC100 CL2 2-2-2 1... (OWC133SD512328) at OWC

Maybe the Cas Latency is not CL3?
