Is running dual channel ddr400 better/faster then running single channel 1.5gb ddr400? I'm contemplating on which is better but i have no idea. any help?

No His earlier thread explains he has 3x512mb sticks and is trying to decide whether to run with 1gb in dual channel or 1.5gb in single channel mode.
I used to have a signature but it disappeared and I just couldn't be bothered writing another so please feel free to ingore this.

Unless you run apps that truly need the added bandwidth, dual channeling your RAM offers little or no performance increase. It certainly doesn't hurt to take adavanatge of it if your board supports it. Increasing your RAM amount to 1.5GB in single mode probably wouldn't show a significant increase over 1GB in dual either, unless you run apps that require the added memory. You'd probably gain more performance by tightening up on your memory timings, even then, we're only talking about a few percentage points.
Here's a recent "dual vs single" article...the link is to the conclusion, but there's 12 other pages if you care to read it all:

Here's a decent article about timings:

ASUS A7N8X-X
Athlon XP 1800+
8.5 x 200MHz
1024MB PC3200 2.5-3-3-7
Asus A9550GE/TD 128MB
WinME/WinXP Pro SP2

My timings on both are 2.5-3-3-8. And should i set in my bios to be running at 400mhz 2:1 ratio instead of 200mhz 1:1 ratio?

Alright now since last night my comp is randomly restarting. You can hear one short beep then it restarts. And just a second ago it showed the blue screen with all those 00x000320430 or whatever (not the exact numbers at all, just an example). But it was to fast that i didn't even get to see a word on it. I havn't touched anything so i don't know what it could be. I looked on the motherboard to see if it was a blown cap.. but i don't see anything leeking and my mobo is about 1 week old. Any help at all? Or anyway to fix it? would reinstalling windows and all that you think?

no, do NOT reinstall windows...do NOT format. This is a hardware issue, not a software issue. It certainly would help if you posted the specs to your system...what board, RAM, CPU, power supply, etc.

K well my comp did it again and i tried to reformat without reading what you said cause it awsn't posted at the time. :S now it does the blue screen right in the middle of windows Setup.
0x0000008e (0xC000001d, 0xBF8777AA, 0xF7A0E17A, 0x00000000)
win32k.sys - address BF8777AA Base at BF800000, Date stamp 3d6de5e5
That's what it says with other s--- saying to turn of cacheing and shadowing. I've completely whiped the partition with windows XP on it and it is still giving me the error.Specs of my comp are as follow
Windows XP home SP2 updates to date.
Asus A8V Motherboard
Amd Athlon64 3500+ venice
2x512 drr400 Dual channel
80gb maxtor HDD
Can't remember the brand of my cdrom but that doesn't really matter.
450watt PS - might be 400 can't remember.
Geforce 6600 GT OC (everytime i joined Counter-strike just before i reformatted it would crash.)Thats basically it. Avg temp of CPU was 35C, avg temp of graphics card was 51C and mobo avg temp was 25c. I don't know what is causing this. Maybe it was the windows update that i just remembered was installed yesterday.

well i figured out what it is. One of my ram sticks somehow became faulty and wasn't letting windows startup i guess. I took one of them out and it worked. Now i just don't know if i should put the bad on in by itself and see if it works or not. If i do this will it screw up my s--- again? I'm thinking on just taking it back and asking for a gig stick of pc3200 and not telling them the stick is bad. What shall i do?

Almost all RAM has a lifetime warranty...hopefully you have the receipt & all the packaging. It won't hurt if you try that stick again, but before you do, download memtest86 so you can test it. Go to the following site & click on "Download - Pre-Compiled Memtest86 v3.2 installable from Windows and DOS"...once you've got it, unzip it, then click on install.bat. Make sure you have a formatted floppy ready to go. Once the files are copied to the floppy, boot off it & let it run for at least one complete series of tests. If you get any error messages, consider the RAM to be defective. Try testing just the "bad" stick, then test the other(s). Personally, the 1st thing I do when installing new RAM is to run memtest...if it passes, I put it into service...if it fails, I immediately return it.

k i'll have to do this on the other computer, i don't have a floppy on this one yet. Havn't needed it :P but thanks for the help i'll post back later how it went.

How exactly do i run this anyways. Do i just put the ram in the slots and restart the comp with the disk in the floppy and it will run tests on it's own or what do i have to do to test for errors? :P

Well i ran one "pass" and no errors were found and i now have the ram in my computer and it's running fine. I don't know what causeed it maybe just some small screw up. Anyways thanks for the help everyone.

Since you have been trying different combinations of ram it is entirely possible that one stick was not fully seated or was making a poor connection. Good to hear you got it sorted.
