picea Posted May 9, 2009 Share Posted May 9, 2009 hi i recently bought the P256 CMFSSD-256GBG2D and the performance on mac os x is really poor. i hope it is a driver or controller issue in the late 2008 macbook pro´s. exact model is a macbookpro5,1 example: i tried to install xcode 3.1.2, at the same time i tried to open safari, the complete computer stuck for 30 seconds. it happens everytime if i do 2 things where one thing is a heavy file operation. hope it will be better in future mac os releases. the good thing: on windows and linux this device is really fast so ramguy, any advice :) thanks in advance picea Link to comment Share on other sites More sharing options...
amro Posted May 10, 2009 Share Posted May 10, 2009 I have one in my MBP, same model as you. I don't have the problem you've described so I would lean toward thinking it's defective, frankly. Link to comment Share on other sites More sharing options...
picea Posted May 10, 2009 Author Share Posted May 10, 2009 hmm thats strange, i dont think it is defect, it runs well under linux and windows. Link to comment Share on other sites More sharing options...
rbmclaughlin Posted May 10, 2009 Share Posted May 10, 2009 Did you do a clean install of Mac OS X, or did you clone your original drive using super duper or carbon clone? I've read that using cloning software often doesn't work well with SSDs. I have the exact same macbook as you, and did a clean install of OS X on the P256. I haven't had any performance problems, but did have a small number of crc errors that haven't increased since the install. Link to comment Share on other sites More sharing options...
picea Posted May 10, 2009 Author Share Posted May 10, 2009 i did of course a clean install. now i put the ssd into a dell latitude notebook with intel sata controller installed a hackintosh version and everything runs fine so it has definately something to do with the nvidia sata controller in the mbp 5,1 Link to comment Share on other sites More sharing options...
picea Posted May 10, 2009 Author Share Posted May 10, 2009 ok seems to be a funny thing, i removed 2 gb of ram out of my mbp and now ssd works. but why it is ****ed up with 4 gb ram? Link to comment Share on other sites More sharing options...
rbmclaughlin Posted May 11, 2009 Share Posted May 11, 2009 Maybe a bad ram module? Link to comment Share on other sites More sharing options...
picea Posted May 11, 2009 Author Share Posted May 11, 2009 it is not a bad ram module. it has something to do how the kernel handles memory stuff when you put more than 3gb into the mbp 5,1. and the nvidia driver for the mcp79 seems to be buggy when it runs with more than 3gb ram. its really sad that apple switched from a stable intel platform to a buggy nvidia platform, i also tested the ssd in a 4,1 mbp with 4 GB ram, and again no problems. the 4,1 mbp has an intel sata controller. really sad :( Link to comment Share on other sites More sharing options...
Legend Posted May 11, 2009 Share Posted May 11, 2009 Make sure you have the latest OS 10.5.6 update for Leopard. I'm aware of previous versions of Leopard having some memory issues on the latest Nvidia based MBK and MBK Pro. Link to comment Share on other sites More sharing options...
picea Posted May 11, 2009 Author Share Posted May 11, 2009 did you read the whole thread? i wrote that i installed a fresh mac os x 10.5.6 from the retail 10.5.6 dvd. and i also wrote that this problem did not occur if i run my mbp 5,1 with 2 gb ram. so please answer only if you have some fundamental information regarding this problem.

Corsair Employee RAM GUY Posted May 11, 2009 Corsair Employee Share Posted May 11, 2009 He did read the whole thread and his answer was correct, from what you have posted and as long as that is a retail version of the Disk I would contact apple and see if they can send you an up-dated Disk if available and or if they have any driver updates that may solve that issue.

Legend Posted May 11, 2009 Share Posted May 11, 2009 I'm sorry if my answer did not provide any value. I am the Applications Guy that goes to test all of our hardware at Apple Labs Infinite Loop Cupertino. The main statement I wanted to make was with the latest OS you should not have any memory issues. Link to comment Share on other sites More sharing options...

picea Posted May 11, 2009 Author Share Posted May 11, 2009 ok thank you guys for your answers. it must be definately an issue with the nvidia chipset. i tested the ssd with the same memory in a dell latitude and again no problems. i already openend a bugreport at apple. but thanks so far for your help.

picea Posted May 18, 2009 Author Share Posted May 18, 2009 hello again, i talked to a support guy at apple today after not getting any answer at bugreport.apple.com. the support guy said i will take care of the problem. after waiting 40 mins on the telephone with nice music i got no answer so i hung up the phone, the call cost me 5 euros. 5 euros for nothing. conclusion for me is that nvidia really sucks hard. i wish back my old 4,1 mbp with intelchipset. what ive tested in the meantime, the 4gb ram of my mbp in another notebook, works. in several workstations, works. i love this ssd and start to hate the crappy mbp 5,1 angry and frustrated about apple picea Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted May 18, 2009 Corsair Employee Share Posted May 18, 2009 I think you stated the drive worked on another system with out any problems, but if not or if you want we can try and replace the drive to rule that out. Let's get it replaced, please use the On Line RMA Request Form and we will be happy to replace it. Link to comment Share on other sites More sharing options...
picea Posted May 18, 2009 Author Share Posted May 18, 2009 it must be the mbp, in every other system with intel chipsets this ssd works great. even in the mbp when i run the mbp with 2gb ram but thats not an option Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted May 19, 2009 Corsair Employee Share Posted May 19, 2009 I am not sure if we have tested that specific system I will try to find out but I know we have tested several systems at Apple and had no issues as long as we used the latest version of Leopard Link to comment Share on other sites More sharing options...
