Dual Channel problems with VS1GBKIT400C3


Longbow

Recommended Posts

I recently built a new PC using this memory. I have an AMD Barton 3200+ 400fsb proc and an Asus A7N8X-UAY 400fsb mobo. Since I built this about a week and a half ago, I have had issues using dual channel mode. Frequent reboots and memory access errors from desktop, during gaming, as well as just surfing the net.

 

For dual channel mode, slots 1/3 or slots 2/3 must be used. I tested both configurations with memtest, and got 4-6 errors every pass on test 5. The failed addresses were different every time. The test showed good 'fffffff' and bad 'effffff'. Single channel mode seems to work fine, no errors when running the sticks individually, nor when together in single channel mode.

 

Any ideas? I would prefer to use dual channel mode obviously.

All of our DDR1 modules are rated up to 2.9 Volts and I would suggest 2.7X Volts with most MB's with about all of our modules. And it will depend on the MB you use, some under volt the CPU sometimes.

I upped the voltage for the RAM to 2.7. The voltage for the proc was set at 1.65, which is nominal for it, so I left it at that. Running memtest again (all in dual channel mode) resulted in errors in test 3 twice, but then a few tests passed as well. Hoping this had solved the problem I reimaged the system. None of the random reboots, however when playing a game (World of Warcraft MMO), the game crashed 6 times with memory access errors, and once to a random violation (error 132 I believe).

 

Some video is jarbled in game as well (MSI 6600GT), causing me more confusion. At this point it appears to be a one or a combination of mobo, RAM, and/or video card. Any suggestions of a good way to test them all seperately? All hardware is brand new and should be compatible.

What you have posted may suggest a power issue since adding more voltage seemed to help the issue. I would try and set the AGP voltage to 1.6 Volts and set the Dim Voltage to 2.8 Volts and see if that helps. Also what make and model of power supply do you have?

I made the voltage changes as requested, memtest passed twice so I figured the problem might be resolved. However, the video issues and crashes continued. I changed out the video card with an FX5600, same crashing issue. Put the 6600GT back in and switched the memory to single channel...no issues for three hours straight. This immediately after three memory access failure crashes.

 

Power supply is a Powerup; Model#LC-B400ATX.
