Upgrade to 6Gb if you can. El capitan likes a lot of ram and 6 is max in a 5,2.

guys hello everybody

I own a macbook white 5.2 2.0 c2d which is runnig fine with 10.7.2 and 2x2 gb ddr2 800

just got 2 stick Hynix ddr2 667 4gb each, popped in and the machine won't boot, just a chime but black screen.

I tryed every combination of the two in the slots, funni is it wuold not boot even with 6gb (4+2).

firmware and smc should be latest avaible and the correct one!

any thoughs?

Not too sure sorry.

My MacBook which I've installed 2*4Gig in is a 5.1 with 1067 DDR3s, so I'd but it down the the OS not liking the DDR2s. With your 2 and a 4 Gig stick have you tried them in both slots?

Has anyone else installed 8Gig with 667 DDR2 chips in an MacBook?

Hey mo679,

I agree with David, I think it's your OS. The hardware looks fine. Has anyone got it to work with Lion? I'm still using Snow Leopard and the one's that got it to work were also using Snow at the time. I was about to upgrade too! Now I'll definitely wait and see if anyone has got it working with Lion before upgrading. Good luck!

Hello everyone!

I know its been a while for the thread now, my brother asked me to upgrade his 5,2 early 2009 macbook 2.0 GHz from 160GB hard drive and 2 GB RAM, i found this thread and he is very interested in 8gigs of RAM, so i am planning to update his software to the latest mountain lion and some nice ssd plus 8GB of ram.

Any advice for the upgrade? Those 8GB kits are epensive dont you agree??

Hello everybody

This is an old post I know.

I have a macbook 5.2 which originally came with 2GB 800Mhz DDR2.

Its now running 4GB 800Mhz DDR2 with OSX 10.8 Mountain Lion

I have been planning to upgrade to 8GB 800Mhz DDR2 still with OSX 10.8

Has anybody tried this configuration?

Khaledw were you successful?

I'm concerned as I can find no confirmed reports of anybody running more than 4GB in Lion or Mountain Lion!

Thanks in advance Rory

Hello, good to hear that, i was unfortunate in running 8gb 667 as i stated it did not even boot, but maybe was just the brand of ram i used, could you tell the type and brand, latency cas etc, you used?

I would like to try again with mountain lion

Thanks

Sorry for reviving an old topic, but my question is related.

Anybody using the Crucial CT2KIT51264AC800 in a MacBook early-2009 ? It is a 8GB kit (4GBx2) at 800MHz. My current RAM is 800MHz (as stated in About this Mac). But I found nothing about Mac compatibility.

Hi jesse,

You seem very knowlegable in this type of field of questions. I am looking for some answers. I just got a 2009 mac 5,2 with only 2GB. I am trying to upgrade to more GB and want to know if I can go from 2GM to 8GB. I know you made an upgrade but was it going from 2GB to 8GB? I am looking for your opinion. If you say yes, i can go from 2 to 8 then I will go ahead and go with that route. Please get abck to me asap!

thanks for the report.

Are you running Mavericks or any particular firmware?

Since mavericks manages memory differently from previous OS filling the ram completly to use it as cache, did you notice slow down or any issue related to filling up the ram as reported from other users?

could you post the firmware number of your macbook?

Have you upgraded to Yosemite? I prematurely and foolishly upgraded and am dealing with the black screen issue that many other have experienced, and am wondering if another reason for the black screen and slowdowns is because I am only running with 4gb of RAM. But now I'm scared to throw another factor in the mix, specially if there's risk of my logic board not being happy with 8gb of RAM.

MacBook (13-inch, Early 2009), 5,2

2 GHz Intel Core 2 Duo

4 GB 667 MHz DDR2 SDRAM

Wonder what the performance is like if you install El Capitan with this much RAM, because I just purchased this machine and running El Capitan with 2GB of RAM(a bit laggy) and will be upgrading to 4GB this weekend.

Has your battery been much worse since you installed this 8gb of ram, though? It must have been eating up your battery like crazy.
