Dual Channel Memory Question
I took the plunge and bought the following;
Aopen AK79D-400VN NForce2 Ultra 400 MB AMD Barton 2500+ 2x256MB DDR400 PC3200 Everything works excellent. Right now, as I'm typing this, it just got done it's burn in (Sandra) at 11x200 (2.2 GHz or 3200+ speeds) at a maximum temp of 47șC. Average was 44.5șC. This is with the original AMD HSF! Can't wait for water cooling! =D My only question is that I bought 2 sticks on RAM for dual channel support but when I populate DIMM1 and DIMM3 it won't even POST. It just sits there beeping one long beep which I assume means there is a memory problem. Is it that dual channel needs all the slots populated? If so I will go out and get a 512 stick to populate DIMM3. The only way I can get it to POST is with the 256 sticks in D1 & D2. I am not new to computers, just the NForce2 chipset. Thanks for your help. Just in case my systems is: AMD Barton 2500+ at 3200+ (11x200) 2x256MB PC3200 DDR400 in Dimm1 and Dimm2 Aopen AK79D-400VN MSI GeForce4 Ti4200 128MB (300 core/530 memory) Creative Soundblaster Live! 5.1 (Need the line in and mic connectors w/5.1 speakers and onboard sound can't do it) WD 80GB Seagate 15GB LG 40x12x40 CD-RW 8xDVD-ROM |

Using 2 sticks of ram will enable Dual Channel, Dual channel is a feature
of the motherboard not the ram. I guess your mainboard will be similar in that the ram slots have 2 together and one on its own, 1 stick of ram in the single slot and 1 stick in the one of the other 2 will enable dual channel. doughnut "CiRcUiT" wrote in message ...

Yes, my mb has 3 DIMM slots with 2 together and 1 seperated from the others.
Two are blue and the one next to DIMM1 is black. (As in Blue/Black/Space/Blue) I put the RAM in 1 and 2 and everything works great but no dual channel (as I expected). I put the RAM in 1 and 3 and can get the board to post but not boot into XP. It resets before the loading screen appears. Maybe I'm not seating the RAM properly. The store I go to has matched kits of RAM specifically for Dual Channel (also with CL2) but these sets are twice as much. If I can't get it to work by next weekend I'll just bring this RAM back and get the matched set. I still don't see why it won't work. Maybe I'll play with my RAM settings also... I'll keep this thread posted... In the end is all this trouble even worth it? Will dual channel really make a difference? "Doughnut" wrote in message .. .

You don't need to purchase matched kits of RAM. They cost too much and don't offer any "real world" advantage. Just purchase two sticks of the same RAM at the same time. Again, make sure the RAM is approved for your mainboard. There have been many posts stating that the difference between Dual and non Dual is marginal in day to day computing. In gaming and OC'ing the answer may be different. I don't game much other than Diablo II or Myst like games and I don't OC since a AMD 2500 Barton Core is fast enough for everything I do. Nystagmus |

I haven't tried DIMM2 and DIMM3. I never thought to try it. D1 & D3 will
post but won't even load XP even with lower RAM timings. I'll try D2 & D3 and see. It would be better if I could find RAM that has been approved by Aopen for the board but the brand of RAM they sell is "elixer" which hasn't been tested by Aopen. This system got a little flakey today at 200x11 so I put the vcore to 1.65 and it seems stable again. Just ran 3Dmark2k3 and got 1711. 3Dmark2k1 is 12684. "Ben Pope" wrote in message ...

Didn't work... Same as usual. Will POST but no xp. I'm just going to bite
the bullet and buy the matched pair next weekend. They better exchange this cheap ass ram ($75/stick=$150 CND) for the matched pair ($240 CND) though. They are pretty good about that sort of thing. I buy alot from them as I build systems for family and friends and friends of theirs and etc... So much for my adventures is dual channel for now. "CiRcUiT" wrote in message ...
