How much memory? - Page 3

mephisto · 2004-07-21, 14:17

Depends on the other processes running on the system.
Nothing will be paged until the total memory requirements exceed the physical memory. After that, paging is based on some variant of an LRU (least recently used) -scheme.
To my knowledge, there is no way of specifying that a particular process should never be paged.

you could disable virtual memory to ensure nothing gets paged, except if you run imagining software or memhungry games.

Turns out my problem was bad memory despite the clean memtest86 result. Switched them with new ones and totally stable. I think w/ 1.0 gig of mem, I don't need a page file. Windows is stupid about paging anyway, eventhough there is 80% free memory, it will still try to page stuff to the disk. Stupid.

I ran Prime95 and I looked at my task manager, and it was running with more ram than is actually available. (I have 768 MB ram, and it was running at up to 832 MB ram.) However, there was absolutely no slowdown in Prime95 NOR computer speed. Now that my ram is clear (I'm on a LL test at priority 1) websites fail to load or load extremely slowly, non-web programs open extremely slowly, and everything in general is running slowly, sometimes very slowly.

HELP!!.

It won't cause any damage it will just make your computer page to disk and thrash horribly.

remember virtual mem is also counted as ram or at least used at it but no u really cant damage ram buy useing to much of it unless u overclock it to a point were it hjust burns up of couse that would be a bad thing

ram

Exit Prime95, it will free any memory allocated,
then just restart it.

Might even work just using the Stop menu item, but haven't tried it.

Doing LL will require very much less memory so Prime95
wont reserve much.

When Prime95 uses this much memory, the memory of the other programs get paged to disk. So the other programs that were running would be slower the first time you use a window etc. (Each Netscape tab is slower for me when I have run some P-1.) Quitting and restarting the other programs would also help.

If you don't want these problems, then lower the memory setting of Prime95, under Options->CPU.
