Memory question

[PhilG]

I am trying to debug some problems with my Tivo that might just be memory related

I look at the Tivoweb Info screen and I see I have

"MemTotal: 13820 kB" (ie about 14Meg)
"MemFree: 672 kB" (ie about 700K)

This is right after a reboot (unplanned)

Is it usual to have so little free memory (compared with the total)? I'll be taking a look tomorrow after some of my daily hacks have run to see if it's gone down any but I'd appreciate some thoughts on other peoples memory usage

Thanks

Doesn't linux use all spare memory for cache anyway?

Why are the Uptimes being posted in this thread so short ???

Dont know what mine is because my Tivo is still in original condition although I think the drive is now getting some errors so time to upgrade it.

We had several momentary power blips a couple of days ago when EDF Energy which crashed the main PC everytime, knocked out 2 of three Digiboxes and reset one of three Freeview boxes. My Tivo, miniITX machine and alarm clocks all survived the interuptions without problems.

[Prof. Yaffle]

Mines short because we had a 45 minute power cut on bank holiday Monday.

Mine just got a little confused about ten days ago. He's getting old now, you know ;) That said, the longest uptime I've had is about 50 days I think.

Not bad for a system with a dodgy hard drive. (Of course it will now decide to fall over. I know I'm tempting fate.)

More to the point, after running Vista MCE on an AMD XP+ 2600 processor with 1Gb of memory, I have decided that I need to upgrade to a faster dual core processor with at least 2GB. You can't help but be impressed with what TiVo achieved with a 50MHz processor and 16Mb of memory!

I was messing about with some utilities that, ahem, can't be mentioned here the day before and as part of that I'd needed to reboot; prior to that it had been up for a couple months.

A quick Excel calc reveals the reboot time to be 15/12/2006 12:05pm. I suspect this was me finding out yet again that touching neutral and earth on an isolated circuit whilst rearranging the kitchen mains sockets can cause the RCD trip thus taking out power to all the house sockets.

170days and still haven't completed the kitchen.....

I upgraded my system board memory from 16m to 32m.

Results Below, make of them what you want???

Did you notice any difference when going frmo 16m to 32m?

[6022tivo]

In a word, NO.

But it was a very interesting butt clenching moment.

a very interesting butt clenching moment.Eeeeeew! Get that image out of my head!

If you hook into your prom to set system memory from 16 to 32, and it is not soldered (surface mount) and working correctly, the system dies and you can not get back into the prom menu to set it back. Bye Bye system board. You have to do a few memory tests in the prom menu to make sure all is ok, before you commit to save the config as 32mb. Quite a achievment when I did it, but no noticable performance increase.

Glad I did it, I bet there are not many 32MB Series 1 UK Tivo's around, great ebay selling point maybe?.

[cwaring]

... great ebay selling point maybe?.
Not if they read this first...

Resurecting an old thread...

Got to Uptime 207d 3h 33m 54s :p

but might have to reboot shortly as I have two items in Now Playing that show as they are still recording and are undeletable.

Using TiVo on screen to delete offers to delete, but still there and TiVoWeb fails with a DeleteError. Nothing in the logs, though I know a reboot usually cures this type of issue.

[BrianHughes]

Never mind that. Is the kitchen finished yet? :p :D

Yes, it only took about 18 months start to finish :D

Sorted out the only remaining snag the other weekend a 50W downlighter that went off after 5 mins, annoying as above the table. Was an original one fitted 7 years ago when house was built. Removed transformer (eventually) through downlighter hole, crimped in new transformer, worked fine, until after an hour went off again !!!!! :eek: :confused:

Finally moved transformer away from downlighter and clear of all the insulation and now works fine, obviously overheating !!! :up:

Well after such a long time, issues this weekend... failed to record Jekyll, not in to-do list or recording history though definately was set to record and end-pad log said it added padding to. Whilst looking through the logs on screen TiVo just rebooted (signal -2).

Last daily mail said 210 days, 17 hours, 59 minutes and 11 seconds (at 5 in the morning).
