I understand this really is boring and you are therefore skipping to a higher comment, however merely wanted to throw that you big thanks – you fixed several things personally!

Hi,
It appears that the Apple senior leadership has made a policy decision to disallow processor upgrades for the Mac Pro (4 core to 8 core). Will the OWC staff consider filling this need?

Thanks much!

From our memory benchmarking, we did not see any substantial performance gains (or losses) between 6 and 8GB of RAM in the ‘Nehalem’ models. While it is designed to use triple channel memory and theoretically 3 sticks of memory in the 4-core ‘early 2009′ Mac Pro and 6 sticks in the 8-core system should exhibit maximum memory performance, most of today’s programs are not written to truly saturate the memory bandwidth.

Until the time comes where Snow Leopard is released from Apple and software manufacturers update or create programs to take full advantage of the 64-bit programming capability that OS 10.6 will offer, the chances of hitting a performance ceiling where 6GB of memory will outperform having 8GB in the machine is going to be slim.

I’m looking quite forward to that time when “real-world” applications will allow us to quantify whether 6GB or 8GB (or 12GB and 16GB using 4GB modules) will pan out to be faster in which operations. In the meantime, we’ve found with most programs available today that more memory allows you to run more programs at once without suffering any performance hits – so your decision to go with all four modules in your ‘Nehalem’ is a sound one.

I just purchased a Quad Nehalem 2.66 and already ordered your 2gbx4 kit to fill all four slots.

Like me there have to be many folks sitting on the sidelines and making do with 3, 6 or 8GB of RAM in the base Nehalem model until 4GB sticks hopefully become more affordable. Can you tell us the pro and cons of 6 vs 8 GB of RAM for the base model?

The nehalems like RAM is sets of three, but would 6GB actually make things run faster if we are not hitting a RAM ceiling with 6GB in these macs?

Thanks for any information!
