Hi,
I want to upgrade the for my MacBook Pro "Core 2 Duo" 2.53 13". I've tried some old DDR3L rams, but no one is working, it's only beeping at boot, than I've to force shutdown. The DDR3L should be no problem it should also work with an DDR3 system.
Is there any QVL to check if which RAM is supported?
IIn the following link is a picture with the tried RAMs: https://www.dropbox.com/s/rm60wy4gpq3fajb/img.jpg
Thanks.
Your computer needs RAM as shown below.
2 - 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM.
1600 is too fast for the MacBook Pro. The simplified RAM interface is built into the processor, and only the EXACT correct spec works.
Users report 'one-click- faster' DIMMS appear to work, then crash three times a week or more.
You’d think, but for some reason Macs are fussy about RAM that’s higher speed rated than the nominal rating. I’ve experimented around and found they work with slower RAM, but obviously with lower performance.
It theoretically shouldn’t be the case with Intel chipsets, but there could be some differences in how Apple sets them up via firmware.
Thank you for your answers.
I think the speed should not be the problem, the tested RAM is only faster and DDR3L should also support the voltage of DDR3.
Maybe the tested RAM has not the quality like Crucial.
A list of working RAMs (QVL) does not exist, so I could look for old RAMs which should work?
Just to correct myself, Intel chipsets no longer contain the memory interface since they shifted to the Platform Controller Hub architecture. Before that they contained a “northbridge” with a DRAM controller.
It might be possible to reprogram the SPD EEPROM on the modules, but that would require specialized equipment and a lot of understanding of what one is doing.
Okay, thanks to all :)
