memory

[FBplmmr]

apparently i have some bad memory sticks.(constant errors with either stick in)
(reads strange numbers in post and sometimes doesnt finish booting)
runs no errors with different sticks

so my question about "scrounged up/ found in the back of the drawer memory"

which would be better 2 gig of ddr mem running at 333 (1 stick is 333 the other 400)

or 1 gig running at 400?


2 gig 333 vs 1 gig 400 ?

thanks for your advice

so nobody knows?  weird

 my question is  about "scrounged up/ found in the back of the drawer memory"

which would be better.. 2 gig of ddr mem running at 333 (1 stick is 333 the other 400)

or 1 gig running at 400?

Anything I'd say would only be a guess.
If you want to use skins, especially on other planes, I'd think the more memory the better.
I'd also assume anytime it has to get something from the disk opposed to memory you have that slight delay and possibly a stutter.
If you want best performance and not a few more bells and whistles probably the faster memory.

Another thing to think of, can you enable dual-channel memory usage if you use the two sticks? That 'might' help but again I'm a nanothought thinker opposed to the gigathought gurus who would know the specifics.

Your option are either 2 sticks of 1gb each at 333 or 1 stick running at 400?


based on that, I'd go with the 2 1GB sticks at 333 and run them in dual channel mode.  Effectively, you have 2GB of memory at an effective speed of 667MHz.  This is the better choice.  For more information on dual channel mode, pm me your email address and tell me you what more information on dual channel mode.  I can send you a pdf from Intel that explains this very nicely and easily with lots of pictures.  


Or just google, "intel dual channel mode pdf"

cool, thanks .. I will google up the dual channel mode thing;)

it depends on how old your motherboard is and more importantly if it supports dual channel - if you know the motherboard model # this is really important.

Anyways, if it does support dual channel you can see about a 15% increase on memory performance if it runs in dual channel - the 2x512mb at 333mhz over the 1gb at 400mhz.

As for the RAM mhz speed - I would again need more information on what motherboard and processor you are using in your computer.

From what I thought, dual channel wouldn't work unless the timings and speeds were the same on both sticks of ram. Seeing that they're different speeds and different types, I wouldn't be too upset if it only runs in single channel mode.

Regardless, 2 GB is 2 GB! I'd say use it, at least until some point in the future where you might want to get a different stick to replace the slow one. The mobo will run all sticks at the slowest speed as a common denominator.

[Kermit de frog]

If the 2 sticks are different speeds, they will both run at the slower of the two speeds.

^-- he said it better


(* but I said it first *)

I recently added another stick of the same memory type, brand, speed, timings(i think), etc, hoping I could run it in dual channel. There's nothing in my documentation I can find regarding how to set it up.

It's an older Asus board, claims to support up to DDR3200 in dual channel, but it only runs in single channel, and I'm curious to find out if I can infact run in dual channel, or if I would need a matched pair to do so.

[Krusty]

If you can run CPU-Z check your memory tab. I think I used to have a mobo and different ram that would list the exact timings in CPU-Z. My current one doesn't do this.

Not all PC3200 has the same timings, and I think they are what is required for dual channel (not just MHz).

Also, if you have 3 or 4 memory slots, make sure the sticks are in the proper slots for dual channel.

Hmmm, running PC2700 (couldn't get the memory speed set to 400, gave up and went with the 333 we had when the box was put together.). Both Crucial sticks of 512, (http://www.newegg.com/Product/Product.aspx?Item=N82E16820145485), in fact I've hunted for the same particular mem stick for some time now, finally found it on newegg last month.

CPUZ lists all info aside from part number/serial number/date of manufacture as being identical. 2.5-3-3-7 timings.

It's an Asus A7N8X-X rev 2 mobo, and has 3 slots for RAM. 2 are next to each other(which is where I put the 2 sticks), with the third slightly removed. In the manual, there is no mention of any settings for dual channel that I can find, nor do I see any labelling or jumpers on the mobo. What am I missing here?

My manual shows 1 and 3 or 2 and 3 populated for dual channel. 3 being the one slightly removed

[hubsonfire]

Ahah, I'll give this a shot. Thanks for the tip.

[Krusty]

That'd be the fix right there. Move the second stick to the "removed" slot.

EDIT: Put one in the slot closest to the CPU, and one in the slot furthest. I looked up an image of it online.
