Does placement of memory in DIMM slots really matter anymore?

[Jaylllo]

I have a Asus A7M266-D. I just stuck another stick of registered DDR in there and now its unstable. (2 sticks total). (slots 3&4)

Would moving the memory around do anything?

Or is my "new" memory stick broken or what?

 

[nick1985]

you should always fill the slots closest to your cpu first and its a general rule of thumb to never fill your last RAM slot. what is your psu?

 

[Jaylllo]

An enermax 431 watt.


Could it be that the MPX chipset doesn't like CAS 2 modules?

I have 2 sticks of Samsung PC333 Registered 512mb.

run memtest

 

[Jaylllo]

It kinda crashes very randomly and within 8 minutes. I'm gonna go dl memtest right now.

Do you have all three power plugs plugged in (main 20-pin, auxiliary 4-pin and auxiliary 6-pin flat)?

 

[Jaylllo]

Yes, all 3 plugs are plugged in and I don;t have a freaking floppy drive anymore so I can;t run memtest. Are there any other good alternatives?

 

[mechBgon]

You can burn a bootable Memtest86 CD if you have a CD burner.

 

[Jaylllo]

Yep, I am going to do that right now.

It seems stable with only 1 stick (by stable I mean it hasn't died in the past 10 minutes so far).

 

[Jaylllo]

Bah, both sticks work fine independently?


Do they really hate each other or something?

Ack any ideas? Im at the end of my resources.

(both passt memtest but not together)

 

[mechBgon]

Hmm... out of curiosity, try reducing electrical load on the system as much as possible (unplug all unnecessary drives from their data and power cables, take out all unnecessary cards) and try it again with both sticks in there. It could be that the PSU is straining to supply enough power on one or more voltage rails.
