I just uprgraded from 1 GIG to 2 GIG of memory and tried a 240 frame render.  the first time it crashed Poser 7 at 41 frames in.  I increased the render detail when I realized the first time it was close to DRAFT.  The second time the system hung at frame 161.

I have Poser 7 on a pentium 4 3.0 ghz with 2 gig of RAM running SR 2.

Would the memory upgrade have anything to do with this?   I just did a fresh reinstall. After the reinstall I moved the backed up RUNTIME folder into the Poser folder to recover everything.

Are their any settings that I  might need redone that would allow this to render?  Prior to the upgrade of memory and the reinstall of Poser it has been very stable. Although on this scene this is the 1st time I tried to render it so am unsure if it is just this pz3 file or if something else is going on with Poser.

Any ideas would be appreciated...I'm afraid something has happened with the reinstall.  tks

You should maybe post it better in the Poser forum.

But however, have you checked the new memory? Not all memory chips fit together - and sometimes there are even bad ones. Just a thought.

Attached Link: Memtest

Another thought Is the memeory you installed.  Is it the same brand of memory you already hadhave installed?  As wabe states if the memory you installed is not the same brand as that already installed in the machine then there may be a mismatch between various setting and timing, case latency, etc., between the two sticks, or was it one?

Also something to consider is the BIOS and have you set the motherboard to accept the new stick of RAM using automatic settings.   Some motherboards will not take ECC and others will not, there is a difference between buffered and non-buffered, and other factors you may have to check into.  Other motherboards have two slots but only take 512 megs per slot and so on. 

Normally you can  check with the manufacturer of your system to find out what brands of RAM are supported.

Thanks for the reply!  I thought I had switched to Poser forum - sorry.....anyway I will try the memtest and run a few more renders of different pz3 files. All the suggestions you made so far have already been checked/tested.  I was more worried that something went wrong on my reinstall...ph

This sounds bad. Check if your memory got correct timing settings in the bios and use the test program. I have had memory that went bed like 3 weeks after i bought it and it took me a week to figure out it was the memory, i just had very random crashes. Especially with large (much mem consuming) scenes.

Try to run the PC with each memory stick alone - and run the following little program for maybe an hour:

If it reads/writes constantly errors (a bad but still somehow working memory stick could count 200/300 errors and more in an hour), to let you at least know, that the hardware is okay, before you look for software problems ... If the stick shows those errors, it's definitely damaged and needs to be replaced ...
