can you run a single stick of ddr3 ram in a computer??? or do you need 3?
if you have an i7 I think you should have 3. I think you can run one but it will run like shit.
if you have an core 2 with ddr3 you should run 2.
yes, you can use a single stick
only memory intensive apps would be affected from dual/triple vs single channel
otherwise,... no diff
If you are looking to save money, don't go with just one though. The Triple Channel is incredibly fast!
Just get smaller sticks of RAM to offset the cost; however, Muskin RAM is only $50 on newegg for 6GB... just a thought.
there's really not much diff specially on specific modules
channeling basically increases throughput bandwidth
a single DDR2-800 stick has a theoretical max bandwidth of 6400 MB/s
double that for dual channel, 6400 x 2 = 12800 MB/s
a single DDR3-1600 has a theoretical max of 12800 MB/s (same shit amirite?)
dual channel 12800 x 2 = 25600 MB/s
triple channel 12800 x 3 = 38400 MB/s (only servers will use this amount)
btw,.. RAM capacity would probably have a greater effect
biggest DDR3 single stick is 2GB
enough for vista and some apps,... but your system would probably be happier with 3GB or more.
of course,... this depends on your usage
ddr3 will "work" in any arrangement you put it in. it will not work with other types of ram, like ddr2 and ddr1. your motherboard must support ddr3
everything except i7 uses dual channel.
i7 has 3 channels of ram. you can use 1 stick of ddr3, to 6 sticks in any configuration.
generally you want the same density, and same or greater speed between sticks.
2 sticks with i7/x58 will run in dual channel mode
1 stick will run in single channel mode
3 or 6,.. in triple channel mode
4 or 5,.. mix of triple channel and single/dual mode
How come the Intel training never told us that? I assumed you wanted 1, 3 or 6 sticks only. Nice post.
not really that much different than before
to have dual channel,... you must have 2 sticks of RAM with the same specs.
a single stick, or 2 sticks w/ diff specs,... it will drop down to single-channel mode.
with i7,... 3 sticks/same specs for triple channel. if not,... it drops down.
RAM configuration pretty much involves the motherboard and memory controller.
you can buy X58 mobos with 3, 4, or 6 RAM slots.
the on-die memory controller in i7 will handle whatever RAM config is installed.
Through Intel's purchase program I'll be getting the Core i7 and Intel x58 Smashmouth sometime this month when the deal opens up. It also comes with Win Vista 64 and Win 7! Woot!
They have triple channel now?
Yeah, TomsHardware made it look pretty badass as well.
Why violate the power-of-2 rule? Why go with 3 channels instead of 4 channels?
That rule only applies to AV's & flashlights...
Probably because 4 channels was too much of a stretch for their memory controller. The addition of the third channel really only benefits those who need that extra memory bandwidth or capacity.
thanks for the info
I'd imagine it's hard enough fitting six memory slots on a desktop board, let alone eight.
They could do it with 4 slots. Dual-channel only requires a pair of slots, but they usually give you 2 pairs of slots. They could turn those four slots into a single quad-channel array. But whatever, I'm still rocking the Athlon XP.
The Intel X58 mobo (and most x58 chipsets) have 6 open slots, for two triple-channel setups.
That's true, but it wouldn't really leave any room for expansion without replacing what you already have.
there's really not much to gain on triple channel,... let alone four.
atm,... quad channel ram in i7 is nothing but added stress to the memory controller.
maybe if we have 6-8 core cpus, it will be utilized.
actually the intel DX58SO only has 4 memory slots.
Correct, I was thinking of the Asus P6-T
