    Anyone know what the latency for stock Apple RAM would be in the new Unibody MacBook (or MBP)?

    I am planning to upgrade to 4gb and found some OCZ RAM for a great price at It is listed at 8-8-8-27 for latency.

    I read somewhere that the Apple RAM is 7-7-7-20 but I cannot find that article so I could be wrong...

    If anyone knows, or know how I could find out, I would appreciate it.

    Buy Apple RAM?

    4gb kit from Apple store (Canada) = $240.

    4gb kit OCZ from = $90.

    Need I say more?

    I have heard good things from OWC but they are based in the states, and being from Canada I would just prefer a Canadian retailer.

    So back on topic...

    I just want to know if anyone can tell me the specs of Apple's RAM. I believe it is CAS 5, but as for latency I do not know.

    I know in most cases it is not noticable but it would seem kinda silly upgrading my RAM to something with a higher latency...

    7-7-7-20 is the normal setting for 1066Mhz DDR3. I'd avoid anything else. Higher latencies are slower, and lower ones tend to have all sort of headaches, especially in a machine like the MBP where the RAM voltage isn't user-configurable.

    Thank you J the Ninja!

    This is what I was worried about. OCZ has Mac memory which is rated at 7-7-7-20 but it costs $30 extra per 2gb stick, so the kit will be around $145 for a 4gb kit. Kinda pricey, might look for some Crucial instead.

    So I ordered myself a 4gb kit of Crucial RAM.

    Latency is 7-7-7-20.. bang on ;)

    Cost was about $110 (Canadian).

    Also ordered a WD Scorpio Black 7200rpm 320gb HDD!

    Got a wicked price on the HDD only $85!!! for the win!

    Thanks for the help everyone.
