Merry christmas!

Yes, I know it's still a bit until it's really xmas, but this week I have my personal xmas.
I went to the computer-center and got myself a few nice things, first I got a cool LinkSys wireless-router, so that I can enjoy more freedom when my wife or I use the notebook to access the net. And then I bought something nice for my PC, another GB of RAM. Now my PC is running with two gigs in dual-channel-mode.
In some way, now nearly everything is dual. ;-) My CPU is dual-core, my RAM is dual-channel, I have a dual-boot and my DVD-writer can handle dual-layer. :-)

So I have increased the shared memory of the GPU to 256MB, and now I can always give KVM/QEmu 512MB (or if I like even 768MB) to play with.
Yesterday I installed Fedora 7 inside KVM, and it runs great! Really! It's like native, with "only" having one core and half a gig of RAM to work with.
I've been roaming around on a few FTPs and it seems they're spreading Fedora 8 already over the mirrors (as expected), but they all seem to have their configuration done right so that I cannot access the directories yet.
Well, when it's finally there, which shouldn't take much longer than a day now (it still says 2 days, but it should switch to one day tonight), I will download and test the upgrade in the virtual machine.
And since we've been talking about taking videos I think I'll capture the process with GTK-recordmydesktop.


Awesome! Happy xmas then!

I'm wondering.. can dual channel for memory be done on the recent Core 2 Duo supporting motherboards? I suppose it just requires both memory modules to be of same size, right?

I have one 1GB and another 512MB DDR2 800Mhz memory.

Thank you. Well, you should


Thank you.

Well, you should see at boot-time if it's running on dual-channel.
If you have more than two slots then you should have two of the same color, probably two pairs which each are in a color. On my board that's two yellow and two black slots. The two yellow slots now are filled with each 1GB Kingston DDR2-667 RAMs, so they're the same size, the same speed and even the same brand (I like to stick with one vendor when I choose one; before I had Infinion-RAMs, but since they don't do RAM anymore I switched to Kingston).
If they actually need to be the same speed and size I don't know, I guess they need to have the same size, and the faster one will anyway be slowed down to the speed of the slower one, so that shouldn't be a problem.

I have four slots and yep I

I have four slots and yep I have two pairs of same color. I should check on startup and in BIOS if it can do dual channel. My guess is yes. However while both of my RAM is 800Mhz, one is Trascend and another Kingmax and they're not the same size so that could be an obstacle, but that's something to check yet.


Yes! It seems to work! As

As I was trying again to get the old computer to work (this thread) I also went and moved my memory chip to the second yellow one to enable dual channel. When I booted it up I saw it quickly saying something about memory running in flex mode. Then later when I read on wikipedia it says this: "Certain Intel chipsets support different capacity chips in what they call Flex Mode, the capacity that can be matched is run in dual channel the remainder runs single channel."

So despite that my one module is 512MB and another is 1GB I get to have dual channel for 512MB of each chip. Basically now I have 1GB 800Mhz in dual channel and 512 MB in single channel. Intel knows their stuff! Eye

Not sure if this means any noticeable performance improvements though, I didn't notice much so far.


I have read that it doesn't


I have read that it doesn't give you very much, but I could actually imagine that it might have an advantage in a dual-core-environment, though I'm not sure about that.
Anyway, I'm sure it won't be worse than single-channel, so it's still good to use it.
