Mac Pro 5.1 Memory question

[artoff]

Hello guys.

I found some cheap memory modules on my local store,(Kingston KVR1333D3N9/8G SLIM) but wanted to make sure it is right module for my Mac Pro

Here is the link for specs

Currently on my Mac Pro i use the original (6x2gb) modules https://www.compuram.de/en/memory_module,hmt325u7cfr8c-h9,hynix.htm

I know that is Kingston not ECC. Should it be problem ?


thanks

The RAM looks good to me. Should able to work at 1333 CL9. And non ECC is not a problem for general task. However, without ECC, it may be harder to diagnosis if there is something wrong in your computer.

Thanks for your advice. I just bought 3 of them. tesed, works amazing...they also have one more, what you think is it worth to buy that one too and use 4 slot? or it will decreese the speed? Because the X58 using triple channel....

The speed will decrease, but unless your workflow can actually saturate the memory bandwidth or running benchmarks, the speed difference should be virtually zero.

At the end, it should be decided if you really able to use all the memory. if yes, forget about the speed difference, because once you run out of RAM, the performance penalty is huge. And if you don't need that much, why not stay at the 3 sticks optimum config?
