    Buffalo PC3700 with ASUS A7N8X Dlx & Barton 2500

    I have the Asus A7N8X Dlx with a Barton 2500 and Buffalo PC3700 Ram 2x256 with the part no ending in "MC" rather than "WB". The ram identifies in CPUZ as "Melco DDR-SDRAM PC3200 - 256 MB". I'm trying to run it in dual channel.

    Problem is I cannot get this thing to post over 190mhz fsb. Well I did get it to post once at 195 @ 9,2,3,2.5 but it wasn't stable. The manufacturer site doesn't have the mem timings listed as far as I can tell so I am kinda running blind here. I now have 2 full legal pad pages full of single spaced notes of various voltage/timing combos I have tried but I simply cannot get where I need to go with it. I've tried high Vcore, high VDimm, high Vchip, and various combos including high all three.

    I am new to OC'ing but I read a ton about it before going with this and was confident I knew what to do but it hasn't worked out. I dunno if I am doing something wrong or if I have defective product, and since the multiplier is locked on my 2500 I don't even have a good idea how to approach troubleshooting it.

    BTW, I pass memtest every time no problem. Its when I am in WindowsXP and start trying to slam it with prime95 that I get unstable. My temps are fine btw, I have a well lapped TT Volcano 11+ and I never get over 47C.

    I'm hoping someone else out there has used this combo and can tell me specifically how they set their mem timings so I can give that a try. Any help is appreciated.

    Try this, remove one stick of memory, run it at 11-3-3 at cas 2.5 with 2.8 volts on the memory, try 11 x 190, then 11 x 195, then 11 x 200, if all that is successful, shut down and try the other stick of memory, same way, you may have one bad stick of memory?

    Yeah I've tried it with just one chip, and with both chips in single channel. It just won't go there. It ran 37 passes of memtest overnight in dual channel at 190 at 8,3,3,2 with zero failures.

    I'm actually 90% convinced I have a bad MoBo because of some other stuff its doing as I describe here.

    That's why I was hoping someone had some actual experience with the setup I am using, to help me become more confident that the board is bad.
