My friend purchased his memory from another manufacturer and he was having
intermittent problems with his new Mac with application crashing.
He followed my advice and purchased the Corsair memory and his Macbook is now working with no problems.
I bought this for a 1 day old White Macbook (late Jan '09 model) to go from 2GB to 4 GB and I immediately had problems on start-up. Also, it caused weird video artifacts and I could only guess that this is due to the fact that the nVidia video card uses motherboard ram for video ram so the corsair ram problems also showed up in video?? I double checked for proper chip insertion and it was fine.
I reinstalled the OEM ram and all problems went away. Reading other Mac boards, others have had issues with this set. However, this product has been out a while and I see here that previously 11 of 12 had good success - so who knows. Regardless, I will try another brand.
By the way, Corsair's product web site claims that "Testing has demonstrated that as much as a 28% overall system performance improvement is achieved with the new Corsair low latency memory modules versus standard Mac upgrade memory". I found that BareFeats (a popular Mac testing site) ran multiple benchmarks that showed that Corsair's CAS 4 "optimized" ram resulted in less than a 1% real world performance improvement over "standard" CAS 5 ram. If you buy this stuff, do so because of its price, but dont expect that you will notice better performance over "standard" PC2-5300 memory. (Obviously, if you are going from 1GB or 2 GB to 4GB you will see nice improvements).
Update 2/28/09: I bought 4 GB of a different brand (OWC) with the same specs and the MacBook works great.
