If the Macbook Pro's are updated to the Penryn processors, do you think they will use the same RAM as the current MBP's or will they go to PC6400?

The reason I'm asking, is because Crucial have JUST dropped their RAM prices again and you can now get 4GB DDR PC5300 for £52.63 :eek: and I want to buy some while it's cheap :D

What are your thoughts? Will Apple use the same memory or opt for something slightly faster?

According to AppleInsider, the Penryn mobile chips use 800MHz FSB

I think Penryn processors use the same memory.

The processors have nothing to do with it, it is the chipset that counts.
 
I'm pretty sure you can go ahead and buy the PC5300.

Unless something drastic happens the new MBP's will probably recognize it.

Also, I was just reading an article how the 4gigs of PC 5300 vs PC 6400 wouldn't be that a big of difference unless you're running benchmarks. Besides that, day to day situations both would probably have no noticeable difference.

I believe it will be PC2-5300 and PC2-6400 RAM.

A way to tell would be to look at the most advanced and up to date laptops in the world.

I just checked Dell's website and it seems like they are still using PC2-5300. Only sleazy brands like "OCZ" ships PC2-6400 SODIMMs at this time, and we all know Apple uses OCZ memory and puts fins around their products because it "looks" faster.

Am I wrong in thinking then that the 667MHz Ram would slow down an 800MHz FSB CPU? Thanks (i'm just really confused).
 
Also might be worth noting, I have just checked my PC and it has a Core 2 Duo 2.4GHz E6600 CPU which is 1066MHz FSB and my Ram is DDR6400 which runs at 800MHz, and my processor is running at its full 2.4GHz.

That's a desktop chip, then. The laptop ones run up to 800mhz front side bus, but as been mentioned the memory controller on the chipset apple uses is limited to 667mhz. Won't see a bump to 800 in their laptops til Montevina. That said, there's no reason not to buy pc6400 if you can find a deal on it.. got mine for $5 less than comparable quality pc5300.. $85 from newegg

Thanks for your input. I just checked the crucial prices and the PC6400 is nearly twice the price of the 667MHz.

So I think I'm gonna buy the 667MHz while it's cheap. (If it doesn't work in the new MBP's I can always resell it :p)
 
The only difference between the Merom C2D and Penryn C2D chips is the 45nm die cut which translates to lower power consumption and slightly longer battery life, as well as bump I think from 4MB to 6MB of L2 Cache. I think the FSB also went up slightly, but remember that is on the CPU, whereas the FSB on the RAM is not the same thing and it is tied as previously stated to the chipset, aka motherboard, which is Santa Rosa, and nothing is changing there. The Penryn is simply a drop in replacement on the SR platform.
