-- Free Memory? (http://discussion.visorcentral.com/vcforum/showthread.php?threadid=534)

My 2MB visor seems to display (in the Info screen) having 1792k total memory, while Palm Info shows having the full 2MB installed. Currently the Info screen shows having 72k of free memory, while PalmInfo shows ~300k available. Rather disturbing to be missing 200k of usable space.

Fragmentation? Nope. I've run Recycle, which shows 57760 Free blocks.

Now while I'm aware some memory goes to the Sytstem, I didn't think it would be that much. Can anybody explain this, or comment on info from their Visor??

Its been my experience even with palms that NOT A LOT of them have perfectly round numbers in RAM either a little under or a little below, my friend's 8meg visor has 7923 or so... i've seen it before... REAL RAM in computers is never perfect either...

There is a simple reason for this. All data on a computer (which this is) is stored in binary, thus all memory chips are made with 2^x bits of memory. ALL of them are made that way, no matyter what the go in. This means that if you got a "perfect" chip, you would have 2,097,152 bits of storage. BUT, being that I design chips for a living (for cars), I can tell you that htere is always some flaws on the chip. This does not mean that they don't work or are defective, just that they pass QC. This is the EE geeks explanation of what is happening

Thanks for the feedback every one. I'm just a little disapointed that a full one eigth of my memory is "missing" (Yes _exactly_ one eigth is missing.) As near as I can tell some where around 5% of the memory should be unreported as this is used as system/application RAM. A 2MB Palm generally shows 1920k available on a 2MB unit.

I'm still interested in getting some numbers from someone else who has a 2MB Visor. the numbers from the earlier poster are interesting because they show almost exactly the same amount of memory missing from a Visor Deluxe. (my math gives me 7936k if they're both missing the same amount of memory.)

I'd imagine that if other people's numbers support mine, then maybe the extra RAM thats unavailable is being used to store some sort of Springboard Code, or is reserved for use by Springboards. I'd be interested to hear from someone who might know.

Actually Palms do not show the full 2048K of memory either. My Palm III shows a total of 1952K.
