I would be interested in any info you come up with on the processors. I always like to max out my setup before I move on to the next build, and I've been wating to upgrade my 1700+.


I can't really say if a better power supply will help. I alway use a big and don't have problems. You would need to run a few tests. One test is to limit the load on the power supply at startup by unplugging the hard drive. I'd unplug the hard drive and then boot up with the memtest86 disk. See if it starts like that. If it does it's probably the power supply.

The heat sinks that come with the AMD processors are fine if you are not going to overclock. I bough my processor as an OEM with no heatsink. I got a Coolermaster AERO 7+ fan with all copper heatsink. It's the birdcage type fan and has a fan speed control knob that mounts in a case slot in the back. It works ok but I'm not really impressed. Anything over about 2400 RPM and the thing starts making a whining noise. at 4600 it's rediculusly loud. I run it at 2400 RPM. Temp runs about 43C max. I used to use the tape and always found it to work with no problems. On this setup I switched to the Artic 3 Ceramique. it knocked off 2 or 3 degrees. One thing I like about the tape is it keeps the heatsink in place. With the gel, you can push the heatsink all around. I've got everything crammed into an Enlight En-7350 Micro Case and the whole thing gets pretty warm. No extra case fan though...only the power supply ones.

Okay, I am up and running reliably with the Barton 2500+, now at 13.0x 181.36 = 2357.
Are there any particular tests that you would like me to run to compare with your results?

I'm running a dual-boot Win98/WinXP setup, using ALL of the on-board stuff... no add-in cards.

Lemme know, and I'll run whatever you want for comparisons, so that you can gauge for yourself whether the upgrade to a Barton is worth it.

Hi I have an A7N266-VM, bios 1005.
I bought a Radeon 9600 Pro, popped it in. Everything seemed fine, until I ran 3dMark03.
I noticed that it said the board supports 1, 2 and 4x AGP. (Which I knew). But that I was currently in 1x!!!! Since the card supports up to 8x, I don't know why Im in 1x.

So I started checking up on this, someone told me to try AIDA32 to make sure, and it told me the same thing.

I'm now trying to find a way to switch it to 4x. But to no avail. I checked the manual, checked the BIOS several times...nothing in there.

I was gonna update the BIOS to 1007, but it seems the only thing it adds is more CPU support.
Any help would be greatly appreciated.

I've got the same problem with my A7N266-VM. I have an ATI Radeon 9000 Pro VIVO card and it is only running at 1X according to Sisoft Sandra benchmark. I'm using the 1007 bios, so that doesn't seem to be the fix. I don't see any place in the setup to choose a setting. It does say that some non Intel chipsets and Video cards will only run at 1X in the tips section.

Figured out how to do it. Seems when I installed my catalyst drivers, I didnt install the control panel. So I went re-downloaded it, and there is a setting in there to switch. Simple as that.

Overall didn't gain much, my score jumped just over 100 in 3DMark03. I'm now just over 3600.

Do you still own XP1700+ DLT3C?
Do you want to sell?

Now I have XP1800+ pally but I only can up my FSB to 140. It won't post @150 and @143-148 crash in 10-30 minutes. I try both Ram PC2100 Spectek and PC2700 AZENRAM. Do you think 'cuz of Ram or I have to increase Vcore?

BTW, how can you increase Vcore on XP1700+ Tbred and how much you can push at stock Vcore?

Hi there!
Where-abouts are you in Canada???

Yes, I still own three, out of the four that I originally purchased here in Ottawa, Canada.
All three will do 2350 MHz, or better, on my Asus A7N266-VM.
One of them, the one in my sig below, will do 2472 MHz, but it's not 100% stable at that speed.

I originally paid $109 CAD for each of the Retail versions, ('Retail' includes a decent Aluminum HeatSink, which I have 'lapped' and a very quiet fan), although the last one that I bought I think the price had dropped to $89.99.
I bought them here in Ottawa at

All have been 'modded' to between 1.7 and 1.85 volts vCore and also had the L3 bridges cut, mostly for a 13.5 multi which seems to work really well in the A7N266-VM.
I've had my fun with them, and am ready to move on, to Bartons, or Thortons, or Applebreds.
So make me an offer that I CAN'T refuse!

Regarding your 1800+ Paly crapping out after 20 min ~ 1/2 hr... that sounds to me like it's getting to hot in there.
Pull the side off of your case and set up a small desk fan blowing cool air directly into the box. See if that helps.

More vCore (from 1.75 ->1.85), would definitely help to get higher FSBs, but the extra 0.10 volts also adds extra heat, so it turns into a vicious cycle.
You would only need to ADD ONE wire to your socket... See...

I have one 256 meg stick of Azen DDR PC2700 here but all it will do in the Asus is 166 MHz (which is what it's rated for, but that's ALL it will do!)
My 256 meg of Crucial PC2700 will run as high as 194 MHz in a different nForce2 mobo, but I'm using Muskin Black, Level II, PC3200 in the Asus now.
At 181 MHz it's running at 6-2-2-2!

I'm in Ottawa (Bank/Altavista). How does $50 for XP1700+ sound?

Hey, I said "make me an offer that I CAN'T refuse"

For $50 I can't buy anything even remotely close to what these things are already PROVEN to be capable of, so I think I'll just keep 'em.
Thanks for the offer though.

I'm at Bank & Heron, (Anoka St.), so we should get together sometime.

For what it's worth, I do have an AXDA1700DLT3C AIUGA0240SPHW that you can have for $50

OK, I started to read just long enough to become confused. I have this motherboard, and a pc with the following specs:

AMD Athlon(TM) XP 2100
512MB (2 chips)
Microsoft Windows XP Home Edition
SB Live! series
Intel(R) PRO/100 S Desktop Adapter
430 w PSU

I thought a luddite like myself should easily be able to add in 512 more meg of ram. After getting conflicting answers on the wisdom of mixing 2100 with 2700, I bought 1 512 pc2700 chip. After first installing it, I got the repeat-a-beep described elsewhere. After switching it around to a different slot, I got a boot-up but Windows crashes every time I opened a program (the pc automatically shut down). One time the BIOS automatically ran and said it recognized a different speed memory and could I tell it what to do. I set the BIOS to default (stupid) and it did not help and for my trouble the PC spends 5 minutes counting RAM at startup and asks me whether to boot from the HD or the CDROM drive. HELP?!

Also, perhaps you can help me avoid future probs, I wanted to buy the Radeon 9600xt, any reason not to?

The PC is an older Alienware and ran great, but I am starting to do digital video and wanted power power power.

1) Is Warcraft3 the only thing that crashes your computer or is there something else?

2)How long do you usually play Warcraft3 before it crashes? What kind of crash is it? (does it freeze the screen, does it reboot the system or does it just kick you out to the desktop?

Depending on those questions above...we can go on as to whether you have updated Warcraft3 with the most updated patch?? And which driver version do you currently have installed for your geforce4 mx440?

If your "PC is an older Alienware" then you are in the wrong forum, and that may be why no one is answering you.

Do exactly the same thing that you did the first time that you 'fixed it'... remove and replace the CPU.

I have no idea of why it works on this mobo, but it does.

Thanks for the advice. This is one tricky mobo, I removed and replaced the CPU for like 10+ times... it was working once and after I reattached everything... it gave me that %$^& beeping again. Thanks to Asus, I'm now a patient man. Anyway, I decided to RMA it for a new replacement, hopefully I'll have better luck this time
