A7N8X2.0 deluxe and upgrading memory

[Devlok]

Hey all. I am having a really hard time upgrading my memory for some reason. First I will show you the type of memory I have.

GeIL DDR RAM 512MB PC-3200 400Hz Ultra- CAS 2, 1T CommandGL5123200U. DDR400, CAS 2, 184 Pin Dimm, 6-3-3 1T Timings,6 Layer Low Noise PCB. Pure Copper Heat Spreader with 3m Patened Thermal Tape.

I have an ASUS A7N8X2.0 Deluxe mobo. Right now I have a 512mb chip in slot 2 and 3 to get dual channel. Running at 200mhz.

Now the problem. I put in the new stick that I purchased, same as the ones above in slot 1 and boot up. Everything seems ok, then wham!! BSoD. PC reboots itself. (Running WINXP PRO) So I take out the new stick of ram and put it in slot 2 leaving the old one out to see if maybe it is a bad stick or something. Everything works fine. So I move the new stick out of slot 2 and put it in slot one thinking maybe the slot is toasted or something and everything still works fine.

Only when I put all 3 sticks in is when I get the problems. Someone told me maybe my voltage needed to be increased some. I went into BIOS and it was set on 2.6. I upped it to 2.8 just to see if it worked. I lft the 3rd stick out and ran the PC to see how it does. Everything worked fine. Shut down, installed 3rd stick and 5min after boot-up BOOM!! ANother BSoD and reboot. I am at my wits end. Not sure if it is a hardware problem or if it is a WIN XP PRO problem.

If anyone could help me I would be greatfully thankful. MY head is hurting, think I will leave it as that. Thanks in advance.

My guess is the mb doesn't like 3 sticks .
I had same issue on a msi board , and a asus board .
It could be that the mb still is confused of running dual ddr or not .
BTW i recommend you to run ths system with 2 * 512 ~ 1024MB ram in dual DDR , insted of 3 * 512 ~ 1536MB single.
You get twice the memory bandwith in dual and that gives better performance than the eksta 512megs memory will give . If you must have a total of more than 1GB mem 2 * 1024 sticks would be better .

Have you tried to losen the memory timings , set loser latency that works , and then tighten it again to i crash. e.g 2,5-3-3-8 or 3-4-4-9
