Hi,
I've been given a 512MB DIMM to use with my cache card.
How exactly do I know that this memory is working as it was 3rd hand. I've looked in the Tivo Web Plus info page but I can't see anything that says that the cache card has some memory.
Cheers,
Chris
When the TiVo boot the cachecard has a splash screen that takes a couple of minutes to get though while it caches.
It will tell you how much memory it sees.

Hi,
I'm getting a silicon dust cachecard splash screen that says:
ERROR: Driver failed to load
ERROR: No information in kernel log
It's not loading any cache into memory then.
The cachecard is a little picky when it comes to which ram it works with. check the compatibilities with the Silicon Dust sites.
also look in the kernel log in /var/log. Look for messages with cachectl or cachecard in them and post back here.
Peter.
Hi,
I've tried both lots of memory that I was given. Neither of them worked and the splash screen was showing longer, numeric errors.
I was also watching the lights on the cache card and the cache light doesn't come on.
With or without the extra RAM, I have always had the errror:
"ERROR: Driver failed to load"
Please can you advise how I can view the Kernel log? I've connected to the Tivo and can view one page of the log but not sure how to see the rest.
I think from memory this happened to me as well. I ended up taking off the cachecard and just giving the contacts a bit of a clean on the TiVo motherboard. I also had to do the chop of the rubber foot as well as it was buckling the board where the cachecard sits in. (chop off the lug on the rubber foot and silicon the foot to the bottom of the case so the lug does not poke through)
[Edited by Petestrash] Also, just reload the drivers again from the Install CD. I finally remembered I had to do it in order because I buggered it up first time.. [do not do this if you are using OzTiVo 1.6 or higher, it may not boot again!!]
[Edited by pjpete]I actually meant to re-image the whole thing and reload the drivers, as per the instructions below, kind of wrote it a bit wrong. But yes you are right, don't do this on the new version :)
Add the appropriate amount of Hard Disks
Re-Image the drives
Then add the network card drivers last
Not sure of any further help until you post the kernel log.
you will get the "ERROR: Driver failed to load" message whenever no ram is detected, this is normal and usually only applies to the cache driver. The network driver should still load fine.
Have you checked with silicon dust that your ram is compatible?
The easist way to view the log is to use the log function of TWP. Other then that, just scroll up in telnet. or use 'cat /var/log/kernel | more' to step through it.
Peter
Doh, completely forgot to use TWP.

It still looks to me that it doesn't like your Ram.
Your driver is the latest version.

I still think you are using either incompatible or faulty ram.
For the third time I will suggest "Have you checked with silicon dust that your ram is compatible?"
Peter
Sorry, for not answering. Yes, I have checked against the specification. I will check again.Quote:

Also what version Cachecard are you using? Before V2.2 cards are even less compatible.
You might also want to try logging a fault ticket with silicon dust. Include your kernel log messages.
Peter
It says:Quote:

All 32Mx8 based DIMMs will work.
All 64Mx4 based DIMMs the follow the JEDEC standard for DQM wiring will work (99% of 64Mx4 based DIMMs).
The two sets of RAM I was given appear to comply with this so I can only assume that they are faulty. I'm taking them back today.
I have v2.2Quote:

It's unlikely you have 2 faulty sticks, try opening a ticket first.
Peter.
I could only find some very generic info in the FAQ and what I posted before was from their forum. They referred to JEDEC information that they had but I can't access that site to get the info.Quote:

A lot of the Support info that used to be there is not on the new site. They have even purged selected posts.
The FAQ on 9th tee is basically the same as years ago, with promises of more answer to come, but they never did.
The cachecard is still sold by 9th tee and your are still supposed to contact silicon dust for support. But I think Jaffa is more interested in HDhomerun these days.
I know when I got my first V1.2 Cachecard I had to try a few different sticks before I found one that worked. Most of these issues should have been resolved by v2.2.
Unforurtunately I don't really have much else to offer. As pjpete said, make sure that the card is fully seated. It can seem it is fully seated, but can actually go further.
As well as cutting the pin for the foot, I also untwist the board supports so it can be lifted when inserting the card.
Peter
Hi,
I did get a response from support. This is what they said:
"The log indicates that the DIMM does not support CL2 operation.
Usually CL2 vs CL3 does not matter as DIMMs that say CL3 still support CL2, just not at 133MHz. The Tivo FSB is slower so running a CL3 rated DIMM in CL2 mode is not an issue.
It is rare but some CL3 DIMMs do not support CL2 operation at all. This is the problem you are seeing here."
I'll talk to the person who supplied the RAM and try and get some CL3 from him.
Cheers,
Chris
I'm glad you received a sensible response.
Hopefully you can sort it out with your supplier.
To clarify Jaffa's response, you currently have CL3 (slower) which does not support CL2 (Faster) even at TiVo's slow 27mhz.
You need either:
1. Any PC66/100/133 CL2 which supports a 27mhz Front Side Bus
2. Any PC133 CL3 that supports CL2 at a Front Side Bus Speed of 27mhz
Peter.
