Worrying

I was looking at buying Geil memory for my MB at Micro Direct in Manchester

The Apple Hardware Test should be able to detect faulty memory.

Also, I would highly recommend Crucial memory if you're looking for a good 3rd party supplier. Crucial is the retail arm of Micron, which is one of the world's largest memory manufacturers. Their prices are very competitive and they guarantee compatibility if you use their memory configurator.

thank you for that link i will try that as soon as i get back home

and :

what those this mean ? that the test can be only made on an iMAC??

Products Affected
iMac (Early 2006 17-inch), iMac (Early 2006 20-inch), iMac (Mid 2006 17-inch), iMac (24-inch Mid 2007), iMac (20-inch, Mid 2007), iMac (17-inch, Late 2006), iMac (17-inch, Late 2006 CD), iMac (20-inch Late 2006)

THANKS

No, it's for all Intel Macs. That particular article focuses on iMacs, but the test procedure is essentially the same for any Intel Mac.

Each memory slot can hold DDR2 PC2-5300 with a maximum of 1GB per slot.*

# Maximum Memory Capacity: 2048MB
# Currently Installed Memory: 4GB
# Available Memory Slots: 0
# Number of Banks: 2
# Dual Channel Support: Yes
# CPU Manufacturer:
# CPU Family: Intel Core 2 Duo 2.16 GHz
# CPU Speed: 2160 MHz

that's a string from crucial test it tells me that i can only have 1 GB peer bank so why those he detect 4GB, from the hardware test i get a message that there is no problem

you think i should change these 4GB for 2GB?
and is it possible that 4GB slows my mac an i do not understand why on www.apple.com i see that 4 gen mac can accept 4GB of ram.

an i am not sure is my mac book 4th gen or 3rd hmm xD how can i check that on my macbook box it says that only 2GB are supported and my question is its becaue of the mother board cant accept more?

thanks

Assuming by 4th gen you mean late 2007, it will support 4GB fine. Prior ones will support up to 3gb (even so, get a 4GB kit, as you need matched pairs for optimal performance). I have had several instances of Crucial's configurator suggesting incorrect memory (speed, capacity, etc...). You need to get a 4GB (2x2GB) kit for that. It uses PC2-5300 (667MHz) DDR2 SODIMMs.

When you ordered the memory, did you order two individual sticks, or did you order a kit?

I have buyed 2 sticks(the model of tge ram is as you describe it) because the kit was not available.any sugestions and my MACPower´s on slower then with 1gb.
