RAM problems
Dear bsd people, I have this amd64 system running freebsd 6.1 with 1 GB of RAM and everything worked very well. Then I've added some more ram, 2 gb extra, to be precise and aft first it seemd everything worked fine. I could load larger files and my java apps didn't give me out-of -memory problems anymore. But everytime I want to upgrade my ports or compile a new kernel, the machine would freeze and the only way to go was to use the reset button. I don't like the look of that. Has anyone had similar experiences? I've had two 512MB corsair memory banks, and added two 1GB banks (oem). I find it really strange that I can use the bigger RAM but compiling gives problems. Could it also be that the banks could be attached better in my motherboard? What should I do now? Continue using it, without portupgrading or compiling a new kernel or ask a new pair of banks at the store? Thanks __ Do You Yahoo!? Tired of spam? Yahoo!

Does your system ever use more than 1GB memory during normal operation? Based on the information you gave it seems to be an obvious problem, bad or incompatible memory. To be certain, take out the memory upgrade and try to buildworld again. No crash = bad memory. It's probably a timing problem, if your new memory uses a slightly different timing than the original memory it will appear to work correctly untill you start to use it, then you will get crashes and other weird behavior. Or it could be the memory slot, dust in it or something. Or it could be the chipset, single-sided vs double-sided memory. Or nearly a dozen other things. But it is probably not your OS. -- -- Perfection is just a word I use occasionally with mustard. --Atom Powers-- ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

As previous suggested , do MEMTEST86 on the new RAM by itself to spot any issues. But it could also be a conflict if using two different versions of RAM.

I actually had a strikingly similar problem. I would freeze on portsnap updates. A -j8 buildworld would always get random segmentation faults. The handbook states the latter is a memory problem. The vendor insisted it was a FreeBSD problem but suggested I read the mobo manual (something I try to avoid). It turned out that when adding the additional memory, they had used consecutive slots rather than skip DIMM banks as the manual suggested (e.g., in my case using only 2 sticks required going to DIMM0 and DIMM2 leaving DIMM1 empty on each of the CPU bank slots, though your details will vary). If your problem was as mine was, it isn't a FreeBSD problem but a mobo set up, bad stick or possibly memory incompatibility issue. I'd think continuing as is will just cause the problem to appear in other ways and if incompatibility or failed stick, you are losing your money. BTW, on AMD64, I used the port memtest to find a bad stick.
