Buyer Beware

I just purchased a new mobo from Newegg (Asus A7N8X) for my new system and I come to find out it doesn't support dual-channel technology, after the fact. I bought this boad because it uses the Nforce2 chipset which I know has dual channel memory support so why in the hell did the manufacturer leave that feature off this board? I wasted $80 on this thing and it doesn't even support dual channel 🙁 There's no point in having all this memory in my system if I'm running it in single channel mode at a low FSB (only 175, rated for PC3500).
Sorry, I had to rant.
 
On a side note, does anyone know why my Barton 2800+ will only hit 175MHz fsb (2.19GHz)? Single-channel memory and a pathetic o/c like that do not make me happy with my purchase...
 
Huh? How the hell do you just have single channel on an obviously dual channel board? What sort of ram are you running, and which dimm slots do you have it plugged into?

2.19GHz is already over the designated speed for the 2800. The 2800 is specc'd at 2.08GHz I believe.

Bah! I've been overclocking for years and I've never come across a chip that wouldn't o/c more than 5%!!! That's just pathetic. Not only that, but I just ran 3DMark2k1 (yeah, I know) and got the following results. Anyone notice anything out of place there? Why is my CPU being reported as a Duron??? I hope that's a bug... WCPUID says I have 512KB L2 cache so I'm assuming I have a Barton... I dunno, I'm confuzzled. I just wish my system would o/c higher 🙁 On the other hand, my Radeon 9600 has turned out to be quite the overclocker with horrible stock cooling (no ram cooling, tiny gpu cooler) and is running stably at 470/702 without any visual anomalies or lockups. I had the core higher for awhile but it was giving me trouble so I had to back it off a notch. Surprisingly the memory still seems to have room to go as I don't have any visual anomalies whatsoever. Not a bad card, all-in-all.

1st and 3rd slots, Geil PC 3500 matched pair (2x512). The board supposedly does not support dual-channel technology. I was as shocked as you are when I first found this out. I know because I've tried all possible memory configurations and no matter what config I use it's still in single channel mode (it even says single channel mode on startup which leads me to believe that it does indeed support dual-channel but the bastards at Asus cut it out somehow to make a cheaper board). Argh!!!
 
What version of the A7N8X do you have? Don't some have dual ddr and some don't? (according to newegg, this is so).
 
From what I've heard dual channel memory is overrated and gives a rather minimal speed increase.
 
It's the -x version, which does not support dual-channel. I just wish I had known that before I bought it, hence why I made this thread.
 
Some people have to up the voltage to 1.7 to make the fsb 200(400). That's from the reviews on the A7N8X-E Deluxe however.

You're processor may be locked in which case FSB is the only way to get higher speed. Are you upping the voltage at all?

I think you're confusing the 200MHz FSB with dual-channel memory... BTW, I have the CPU Vcore @ 1.75V right now, and that's all I can get. If I give it more juice it seems to want to die. I wonder if perhaps I picked up a TT Volcano 11+ to replace my 7+ that might help things a bit? I'm going to add a couple exhaust fans to my system and get some decent cooling for my video card while I'm at it so why not? Hopefully I can get this whole thing straightened out...

Thanks, but I don't really want to sell it after all the time and money I've invested in this thing getting my new media center setup... It would be kind of a waste to go back to my old setup, even if I did have a few hundred bones in my pocket.
 
Update: I just bumped the CPU Vcore and DDR Vdimm up to 1.85V and 2.8V respectively. I'm going to get some better cooling tomorrow (today now, I guess) so hopefully I won't have to run the voltages that high for too long to keep this thing stable. Right now I've got it running at 180MHz FSB and it seems to be chugging along just fine. Was doing some stress testing and haven't encountered any errors yet so at least I've got a little something else out of it. Now tomorrow should bring much more promising results with improved cooling for my entire system.
Anyone run their Barton @ 1.85V (showing 1.82V) @ over 50 degrees C 24/7 for any extended amount of time yet? Good idea, bad idea? This is my first Barton core CPU and I know my previous Tbreds have treated me pretty well when it comes to o/cing, just wondering if the Barton will do the same (eventually).
Edit: not successful 🙁 Had to bring it back down to 177MHz and 1.775V to be safe, system was unstable at 180/1.85 or anything above 177MHz. Hopefully new cooling will solve that. I check my temps in the BIOS after one of the reboots when running at 1.85V and the CPU temp was at like 67 degrees C :Q Hopefully that won't be happening anymore...
