Red Five Posted September 1, 2012 Share Posted September 1, 2012 Definitely 8GB max RAM. I upgraded from 4G to 8G as soon as I realized I could. I sometimes have to test things in various operating systems, and need lots of RAM for virtual machines. Oh yeah, that's definitely 64-bit only. I haven't run a 32-bit OS ever on my D630; I'm basically switching from Ubuntu to Mountain Lion this weekend. Link to comment Share on other sites More sharing options...

seb43654 Posted October 3, 2012 Share Posted October 3, 2012 Hi, I've already installed Lion succesfully in my D630, but I have only 4GB RAM (2x2GB). What it the maximum RAM supported for the D630? 8GB (2x 4GB)? I have A17 BIOS version. Also, I want to upgrade the hard drive and I'm thinking in a SSD hard drive. Did any particular model that works perfect in our D630? I do not need much capacity, but performance. Thank you very much! It is definetly 8GB for version A17 bios, and in my D630 I have a OCZ Vertex 2 in my primary sata bay, and I swapped out the DVD drive for a 250GB 5400RPM HDD which has my home folder on. Hope this helps, Seb Link to comment Share on other sites More sharing options...
Red Five Posted October 3, 2012 Share Posted October 3, 2012 ve got 8g to be honest I believe anything past 4g is a waste ,simply because front bus speed ,and limited hyperthreading , I also havent notice any significant improvement worth the expense If anything I recommend getting more quality ram , and as fae as a SSD goes , huge difference, in speed , I use a kingston 128g , Ive already ruined 2 harddrives with the laptop falling of the bed ,. with the kingston you could play hockey with it ,and boots every time , you wont regret the investment. More RAM is always a good idea; more RAM means less need for and time spent on swapping to disk. And for systems with an SSD, less use of swap is a Very Good Thing. Excessive swapping can kill an SSD very quickly. If memory serves, HyperThreading was never part of the Core2 CPU feature set (Core and Core2 are basically multi-core 64-bit extensions of the P3/P3-mobile architecture, while the Core i series adds HyperThreading from the P4); it was only available on the Xeon CPUs around that time.

Administrators Bronxteck Posted October 4, 2012 Administrators Share Posted October 4, 2012 another good thing is to set pmversion from 3 to 0 with an ssd so that it wont dump your ram to the ssd on every sleep and shutdown so if you have 4 gigs of ram or more lets say it writes it to disk unnecessarily. fine though for regular hdd. you can set it in terminal with sudo pmset hibernatemode=0 info from man pmset hibernatemode = 0 (binary 0000) by default on supported desktops. The system will not back memory up to persistent storage. The system must wake from the contents of memory; the system will lose context on power loss. This is, historically, plain old sleep. hibernatemode = 3 (binary 0011) by default on supported portables. The system will store a copy of memory to persistent storage (the disk), and will power memory during sleep. The system will wake from memory, unless a power loss forces it to restore from disk image. Link to comment Share on other sites More sharing options...
peterW Posted October 4, 2012 Share Posted October 4, 2012 thanx for the advice, i bought 2x Kingston kth-zd8000b 2GB SODIMM PC2-5300 667MHz and a multibay PATA (IDE) HDDCaddy 12.7mm Universal(pata => sata) for 500gb hdd. can i use SSD Sata2 of Sata3 in my primary bay. greetings peter Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted October 4, 2012 Administrators Share Posted October 4, 2012 the d630 can handle ddr2-6400 800 mhz so-dim ram. bumping the bus up if your cpu also has 800mhz bus really helps; osx likes faster bus speeds more then anything else.
