I have two identical gig sticks, but I might have positioned them incorrectly for dual channel to work, any idea how I can quickly check it?

Thanks, Steve.

First of all could you tell us your system specs. Especially the motherboard. Dual channel runs automatically when you have two identical sticks in the two slots with the same colour I believe. Theres no option in my bios which says enable or disable dual channel.

could you post your system specs?

I have a Gigabyte Motherboard. I run my memory in dual channel. I can get that from bios readings
at startup.

I also believe that dual channel slots have similar colors. For example, the two slots with be red.

bye...for now.

On the post screen it will say 'Dual Channel' or '2048mb RAM 128bit'

Or something similar.

Dual channel = 128bit
Single Channel = 64bit

Hope this helps.

I'm pretty sure CPU-Z will also tell you.

When your PC boots... the first bunch of stuff displayed should have info about cpu speed, Hdd's and so on. Within all that crap you'll see how much RAM you have installed on your machine and directly after it... whether it's running in single or dual channel mode.

As far as i know... there is no specific setting in the bios for this. If the mobo supports it and the RAM is compatible it will automatically switch to dual channel mode.

I can't quite remember now, but when I added the ram my motherboard manual contradicted itself in regards to the dual channel position. I have an MSI K8n Ne04f mobo and an athlon 64 3500 venice core and 2x1 gig sticks of corsair value slect ram. I can't see any of the info when windows boots, it does it too quickly.

My commit charge in task manager is 3939M if that helps.
I'll go check inside my case now..

When you go boot next, go into your BIOS. Under advanced settings or something, you should have an option for 'power on self test (POST)' make sure its enabled.

You should see all that info when it boots

Okay it says its dual channel :)
I have the sticks in a green and purple slot though... I think my manual told me to put them in the same colour slots somewhere, but then it said they had to be in a certain No. slot for dual channel and it contradicted itself. Oh well it said dual channel in the POST, so it's all good. Cheers.

Some mother boards are different, some ram you have to have in the same colour and others in different colours like I had a MSI mobo and had to have 1 stick of ram in the green slot and 1 stick in the purple slot but now I have a Epox mobo and there’s 2 black slots and 2 purple slots and I have to have both sticks of ram in the purple slots for duel channel to work so there all different, as for not seeing your post at start up on some systems you will get the mother board’s Logo load over the top of your post, make sure In you Bios that full screen Logo is disabled

Depending on how its worded it can be confusing.

It might be that it said each 'channel' is a different colour. i.e purple = channel 1, black =channel 2

And you must have 1 stick per channel for dual channel to work. i.e 1 in black, 1 in purple.

Other boards will have it colour coded so you put the sticks in the same colour slots, ie. each channel will have 1 purple & 1 black slot.

I think thats pretty much what was said above.

Be nice if the motherboard manuals were a little clearer. Both my last ASUS and my current MSI give the worst possible explanation on how to get dual channel running.

The application CPU-Z will also tell you if your running in dual channel mode. Your motherboard's manual should mention which slots to put your memory in to take advantage of dual channel. Like other's said, many of the manuals are written in bad english and are hard to understand especially those coming from MSI, as I have noticed in my expierence.

From your users manual:

MSI Reminds You...
- Dual-channel DDR works ONLY in the 3 combinations listed in
the table as below.
- Please select the identical memory modules to install on the dual
channel, and DO NOT install three memory modules on three
DIMMs, or it may cause some failure.
- Always insert the memory modules into the GREEN slots first, and
it is strongly recommended not to insert the memory modules into
the PURPLE slots while the GREEN slots are left empty.
- This mainboard DO NOT support the memory module installed
with more than 18 pieces of IC (integrated circuit).

Get Hippied out!
