I would like to add some memory to my not so new system and would like help. I think I put myself in a corner with earlier, ill-informed purchases. I have 3GB RAM now, 2 more should suffice for my use (linux, lots of windows/apps/tabs open but no games etc.)
Thank you for any input - I did read up on this but remain confused.
Really short version: Can I mix these in adjacent slots?
DDR2 800 2GB 4-4-4-12 2.1V
DDR2 800 2GB 4-4-4-12 2.0V
The longer version: I have 4 DDR2 800 slots, ABIT says 8GB max, I have a matching pair of 512MB modules and a single 2GB module (full details of system below). Neither latencies nor voltages match between the 2GB and the paired 512MB modules.
I've read that you can mix latencies, they just run at the longest latency, but that mixing voltages is the problem. I also read that you need a pair to run in dual channel mode, otherwise they run in slower single channel mode. However, I can no longer find a single module that matches the 2.1 voltage of the 2GB.
Can I use a 2.0V 2GB in the matching slot with the existing 2GB module if the latencies match, as asked above?
Would I be better off just swapping out the 2x512 for a matching 2 x 2GB modules? I know I'd be better total memory, but I don't need that much more and the cost really matters, plus I'd still have that slow single 2GB module (if I understand correctly)
I'd prefer to buy from NE but am open to suggestions.
Searching only for DDR2 800 (and up) and 2.1V only gives one result, a 4x2GB set for ~$140, more than I have.
When I instead search only for DDR2 800+ and Cas 4 gives more results, for example:
$34 Kingston HyperX 2GB DDR2 800, Cas 4, 2.0V, 4-4-4-12
Or
$64 G.SKILL 4GB (2 x 2GB), Cas 4, 2.0V - 2.1 V, 4-4-4-12
The 2GB PatriotPatriot Extreme Performance 2GB 240-Pin SDRAM DDR2 800 Desktop Memory Model PEP22G6400LL, Cas 4, 4-4-4-12, 2.1V
Details:
MB: ABIT NF-M2 nView AM2 NVIDIA GeForce 6150 Micro ATX AMD
updated bios (current -1)
MB Memory specs:
4×240pin
DDR2 800
Dual Channel
ABIT lists max as 8GB
I first purchased
2 X Wintec AMPO 512MB 240-Pin SDRAM DDR2 800 3AMD2800-1G1K-R (part number is for both sticks as kit)
Cas: 5
Timing: 5-5-5-12 (I thought Cas = first number here?)
Voltage: 1.8V
I later added
1X Patriot Extreme Performance 2GB 240-Pin SDRAM DDR2 800 Desktop Memory Model PEP22G6400LL
Cas: 4
Timing: 4-4-4-12
Voltage: 2.1V (according to what is on module's label and Patriot's website, though newegg says 2.2. I'll go with 2.1V)
In case it matters:
CPU: AMD Athlon 64 X2 3800+ Windsor 2.0GHz Socket AM2 65W
HDs: WD 250GB, Samsung 1TB, Seagate 1TB
No overclocking, plenty of swap space, no raid. Have added compcache and tuned swappiness, was thrashing like crazy past month. Expect to keep this computer for a few more years but any RAM I buy will not be usable on next one, of course.
Again, thank you - even more so if you made it this far!
