Macbook Pro Corsair 4GB Ram

[pcdemon]

Hey All

I just purchased the low latency ram by Corsair. I know there has been some discrepancy's over the added performance as Corsair shows stats from the older and slower mac's. If anyone with a 2.5ghz Penryn Macbook Pro has the crucial ram or the other low latency ram could you please post your benchmark stats please when I get the ram I will run the same test (please post software used) so that everyone can have a legit comparison.

i see larger number but does that mean faster? or slower???

what was the price of the memory kit you bought?

 

[pcdemon]

The memory does show to be a bit faster I ended up paying 148.90 shipped. The Ram was 122.91 + shipping. from ncix.com

Corsair has published a "white" paper showing their new low (CAS 4) latency 4GB memory kit (2x2GB) for MacBook Pro and other Apple laptops running Photoshop 20% faster than a normal (CAS 5) latency 4GB kit.

We ran our own set of benchmarks with the Corsair memory including Photoshop, Compressor, and After Effects "stress" tests. The average advantage with the low latency memory was 1%. (We tested on a "Penryn" MacBook Pro 2.6GHz.)

We ran a 64 bit, multi-core version of STREAM. It was a consistent 6% faster with the low latency memory.

We never saw anything approaching the 20% claim of Corsair for real world apps.

So is a score boost of 11 worth $150? I'm not sure how much "real world" difference 11 points do.

Seems like a crock to me

here's my 4gb of regular crucial ram score:

 

[amoda]

Maybe the difference has to do with you having a 3,1 MBP while he has a 4,1?

I have the low latency g.skill memory.

see attachment for results.

should also say I have a 2.6 GHz Penryn MBP.

 

[jboyd122]

Sounds like a crock to me. I had the Corsair low latency RAM on a desktop PC I built a few years back and I can surely say it is in my opinion that the performance gains claimed are not apparent. I'm running 4GB of Crucial RAM in my 2.5 Penryn MBP. Results are from XBench.

Remember the low latency only helps if the laptop actually runs at those lower latencies. If it still tries to run the memory at standard slower latencies then you won't see any gain.

You should try running CPU-Z in windows to see the actual memory latencies.

I too have G.Skill CL4. i only paid somewhere around 90 for it and have had no problems! Geekbench score is higher than many other 4GB RAM MBPs on their leaderboard.
