Memory boards - 16/07/2004 10:11

Hi.

OK. Here's the deal. I have a design for a memory upgrade board for Mk2/2A boards which (although I haven't yet built a prototype) I'm pretty sure will work quite nicely. After much thought, I was unable to come up with a good way of getting it above 64MB, but that should be sufficient for most people. I had hoped for 128MB, but it turns out to be pretty much undoable.

It would be possible to add other things as well, but after talking it over with Hugo we decided there wasn't all that much point. I had considered both 100mbit ethernet and USB host, but dumped them for various reasons:

1) the data rate from the USB host controllers suitable for use in this application are dreadful, according to Hugo, and the controllers consume enormous amount of idle bus cycles, thereby slowing things down.

2) for a number of reasons that have been thoroughly explored in past discussions, 100Mbit ethernet in this application wouldn't really achieve much that 10Mbit doesn't, and complicates things quite a lot.

3) There are supply problems with some of the parts for both USB and ethernet

4) It may well not fit anyway.

So, the current plan is for a PCB which will fit to the underside of the main board, attaching to the test points. It will have 8 64Mbit DRAM chips giving a total of 64MB of ram, and will require one patch wire. On a MK2A you could omit the wire and still get 48MB. On a MK2 you will have to remove the chips currently fitted to get the full amount.

It is a completely surface mount device, and would as such not really be suitable for selling as a kit. I will therefore have to get the things made in batches as completed sub-assemblies, which will then need to be fitted by one or other of the prople floating around who are good at such things.

I am provisionally aiming at a price of about £90-100, and the advantage of doing it this way should be shorter lead times and less supply problems than the tuner kits have. So far, I have contacted a company who can do the assembly, have routed the PCB, and I'm waiting for a quote on quantities of the RAM and on manufacture of the boards.

Anyone interested?

I'll take one!

Note about 100mb/s ethernet: with more memory, the underlying assumptions have changed, and it would now be able to have a more noticeable impact on I/O due to Linux's caching (which now has more memory to play with).

Cheers!

Yep, I'll take one.

Do you still have to remove the original chips for a Mk2a? I assume yes but you only mention that it's necessary for the Mk2 in your post. If not, the original chips are redundant, right?

And there is enough room underneath the PCB right? I don't remember huge amounts of space between the board and metal case but we are talking only one surface mount chip thickness plus PCB (~3mm?)

Re: Memory boards - 16/07/2004 10:46

I am, of course, interested. Four, please. But, a question: what does this do to people with enhanced memory via the stacking method? Does all of the memory need to be removed?

Re: Memory boards - 16/07/2004 10:53

The board adds 4 identical banks of 16MB, and duplicates the bank0 set currently present on a MK2A. Obviously, this isn't going to work all that well. The idea is that each bank can be disabled by means of a switch on the memory board, so in the case of a MK2A you would turn off the first bank. This would still give you 64M, as the original memory would be used.

As for room, there's a whole 2.5-3mm available! 0.8mm for the PCB, 1.2mm for the chips, 0.1mm for the insulator sheet on each side of the PCB, and loads of room left over

Re: Memory boards - 16/07/2004 10:55

Well, if you've already butchered your poor board, you could disable the appropriate banks on the expansion board to compensate. I would recommend removing the added stacked chips, but it shouldn't be absolutely necessary. You would still only have 64MB though.

Re: Memory boards - 16/07/2004 11:01

Ah, my board has been hacked a few times already - digital out, illumination hack. The memory was just the most recent. Still, if it is a matter of only gaining an extra 16MB over the existing 48, it may not be practical. Still, I would like to get the boards anyway, just in case I run into trouble later on.

Re: Memory boards - 16/07/2004 12:31

OK, so it looks like my initial test batch of 25 is gone already! I may have to do a bigger initial set.

I have heard back from the memory supplier, and the chips are in stock and rather cheaper than I feared. So that's all right then.

Just the PCB to go now.

Wow. It amazes me that so many of us are willing to spend close to 200 bucks on a small RAM upgrade. Maybe i'm missing the huge benefit here, but that's a chunk of change. Someone fill me in... why? Surely it can't be to save drive spinups for wear and tear... a new drive costs less.

Oh, and standard disclaimer applies... i'm not dissing the product since well... as we all know Patrick is THE MAN. Just trying to grok it. I want it but i don't know why. heheh.

Agreed, the price seems a little steep compared the the "stack the chips" method, particularly if you don't really feel the need to go beyond 32Megs. What are the advantages of this method? Will these boards be any easier to install? Why are so many people who already have memory upgraded empegs so excited by this?

Of course, I'm probably in for one board myself since I would like some additional memory and it looks like this is going to quickly become the standard way to do it.

What are the advantages of this method?

Primarily, reliability. In an automotive application, vibration will remove patch wires eventually, unless you use a LOT of glue. Plus it will be quicker to assemble and if necessary debug.

Getting to 48MB the other way is difficult, and getting to 64MB incredibly so. 64MB also requires some creativity to deal with the limited clearance between the memory and IDE cable. I raised my drive tray, and peakmop separated his IDE cable so he could move it out of the way. Neither of those measures could be described as routine. Whilst I'm not too concerned with reliability issues for the players that I've done (lots of glue, heh!), the new method should be a much better way to do it.

I'd point out that the 'old' way is still going to be a cost effective 32MB upgrade (~$80 installed) for those who can't justify the (estimated) $240 installed cost of the new 64MB upgrade. Paul still has chips available for those who chose that route. (And it shouldn't preclude an eventual 64 upgrade either).

For anyone questioning the cost of this new method, a 64MB upgrade done the old way would end up costing about the same anyway, ( 3 * $30 chips) + ( 3 * $50 installs) = $240.

Re: Memory boards - 16/07/2004 19:34

My own plan is to get one of these upgrade boards from Patrick, and then find some willing bloke to send me their player so I can install it and test Hijack on it -- making any Hijack changes as required to get it all nicely supported. And then to return the upgraded player to whomever loaned it. They pay for the parts, but not for the actual installation.

For my own players, I'm sticking with one set (16MB) of stacked add-on memory. I'm not wealthy enough to actually install the 64MB kits onto all of my own players!

Re: Memory boards - 16/07/2004 20:05

I understand the reliability side... but no one (save for Mark and his webserver) has really justified why you'd need more RAM in the first place. Help me out folks, i'm trying to justify the cost to myself here!

Re: Memory boards - 16/07/2004 20:09

I'm up for one kit.

And Loren, more memory also allows use of larger music databases. Think of it this way, in theory, a 100 gig player filled with typical music would have a database 5 times larger then a 20 gig player. Thus, less cache. Bu upgrading to 32, or 64, you return the player to a state where it has plenty of cache room, and also has enough memory to do the database rebuilds. It was discussed at the meet that database rebuilds don't currently enable swap, leading to some of the crash issues in 3.0 alpha on database rebuilds, due to the memory overhead of the player app running.

Re: Memory boards - 16/07/2004 20:13

Well, once units with 32MB or more become common, I fully intend on adding some major new functionality to the hijack kernels. The kinds of stuff I've held off in the past due to memory consumption.

You know.. like vertical playlist menus.. NFS server (just a kernel config option), etc..

It has Ver 2 software but if you want to use it feel free to install any version you want. Just let me know what you want to do. (This means I'm in for one board )

Re: Memory boards - 16/07/2004 23:08

If I play my root playlist on my Rio, it won't remember it between reboots. My empeg (mk2) won't even play the root playlist in the first place. I'm hoping that more RAM will help this. Either way, database rebuilds are painful. Mark has mentioned the web server stuff will be faster, and I've been getting more use out of that as well.

Hard drives are cheaper, but data is priceless.
Posted by: tman

Re: Memory boards - 16/07/2004 23:23

Isn't the can't remember the playlist problem to do with lack of space in the dynamic data partition? The space reserved for the current playlist has a hard limit. Extra RAM won't help in this case. You'll need to get the empeg guys to see about modifying the format of the dynamic data partition.

Have you ever considered how much time it will take to listen to all of the stuff we are trying to cram onto our empegs' hard drives?

Quick math:
1 min. worth of MP3 song at a descent cbr of 192 Kbps - roughly 1.4 MB. Given the largest currently available empeg space - 160 GB, say 155 GB (158720 MB) of which is usable, there are approximately 113371 min. That's 78.7 days or 2.6 months!

Re: Memory boards (more data - more time) - 17/07/2004 01:17

I actually joke about that all the time to my friends. I've never done the math and assumed it was more than that. I remember when I got my first 12GB player, I used to joke that I could drive to and from California a few times without hearing the same song twice - now I could do more than that!

The point isn't having "hours" of music but rather having the means to hear "what you want, when you want." This is very true when DJing, so I can meet requests, but it's also great when driving around town. I say to my passangers, "What do you want to hear?" Someone who hasn't ridden with me might reply, "What do you have?" To which I'll repeat, "No. What do you want to hear?" Of course, even with my 140gb, I still get stumped all the time!

Mark, would you plan to release "low mem" and "high mem" versions of HiJack for us poor 16meg folks in the future?

::shudders:: But, what if Mark doesn't offer low mem version? And what if Patrick's memory board goes out of production? I'll be stranded at 16 meg, software will be incompatible, my database size will be too big, and ALL that. Oh man, the threat of empeg add-ons going out of production is SO strong....

I noticed my 12mb empeg can not even play the root playlist whereas my 16mb RioCar can (but will not remember it through reboots). So I guess the dynamic data partition is used to store info between reboots and must be smaller than the 16mb used by the RioCar to load the playlist during operation?

Repartitioning disks without hosing content is reasonably hard. But the use made of the dynamic data partition isn't very efficient, so we could rearrange it to give more of its space to saved running-order. In fact, we've been threatening to do this for the whole of the v3 era, and it wouldn't surprise me if I'd threatened to do it for v2 final. But I just haven't got round to it.

Without a lot of work (which isn't going to happen) to v2, such a rearrangement would completely bork anyone who switched back from v3 to v2.

Edit: Well, I say "completely" bork; it'd bork their bookmarks and play counts. Whether that counts as complete borkage depends on one's individual bork threshold.

Not at present, no. And the stored running-order comes at the beginning, not the end; changing the code to stat the partition to find the endstop would solve the 28K limit on total fids but not the limit on stored running-order sizes.

Surely changing the code to use only the bytes it needs, rather than all 512 would be a good idea as well. Doesn't each entry only use 32 or 64 bytes (can't remember which).

It's certainly not very much, but the point of using 512 is that it's one sector and can be written atomically; that is, screwing up a write (due to powerfail) can only affect one track's information, not all its neighbours too. But yes, this consideration is probably not worth it, compared to the problems people are having with >256K running-orders. Reducing the FID-dynamic data space and handing the free space over to running-order storage is exactly the plan for, er, sometime in v3.

Actually, that has not been true for most of the past decade or so.. Internally, most IDE drives will rewrite the entire physical track, or a large portion of it, when "rewriting just one sector".

Here's a thought - since we are on the memory redesign, how about CPU - is it conceivable to upgrade to, say PXA255 XScale 400MHz? Then something crazy like video-4-empeg would be within reach

Re: Memory boards - 21/07/2004 05:24

400Mhz ?

Even my Pocket PC has a faster XScale than that

My 624Mhz Pocket PC is the second fastest processor I own...

Re: Memory boards - 21/07/2004 11:28

PXA255 isn't pin compatible with the StrongARM SA1100 inside the empeg so that'd be one ugly expansion board

Hmm, then you'd need to upgrade the display as well. Which to be honest is the wrong shape unless you watch your films in cinemascope. The empeg hardware is great but it's the software that is absolutely killer.

What would be cool for a empeg redesign is a pullout screen the a little larger than the size of the Rio Central screen.

I was about to buy a Mk2a, just so I could upgrade the memory.

Hopefully, this will save me the hassle.

I'll take two.

One please. I'll hopefully be able to get this installed the same time I get lighted buttons.

MLord if you still need a volunteer for a RioCar model, I've got a spare.

Re: Memory boards - 18/08/2004 03:26

That's exactly my point - buy empegs for the memory boards.
This gave me an excuse to get a little brother for my primary machine.

Satisfying an itch up my b**t I went and made another heat sink [see attachment]. This one came from an old Pentium 200 MMX.

You know, I'm getting better at those. Maybe I should ask Tom to reserve me a "Heatsinks" spot beside Tuners, Sleds, Buttons.

Time to update that signature of mine

Re: Memory boards - 18/08/2004 09:53

Why have you got a heatsink on your CPU? Is there a point?
Posted by: peakmop

Re: Memory boards - 18/08/2004 15:31

Yes, somehow I think it will prolong the life of my CPU on the hot days, but that's not the main point.

I have <sensored> cooking up, I will let you know how it goes.

Re: Memory boards - 19/08/2004 02:30

Not only that, he has a system fan!.. Hmmmmm have you overclocked your empeg ? :P

Let me know when you have liquid cooling in place
Posted by: canuckInOR

Re: Memory boards - 20/08/2004 03:47

Not sure I'd want to see that, especially with an Empeg. Seems most liquid cooling around this BBS is a result of funny comments.

Re: Memory boards - 24/12/2004 11:47

How is the progress in this dept?

I would like to have two boards when/if they become available

Could this be something for a new builder? Some of us are prepared to hose our disks to gain partition sizes. I want more binaries on my / but with a fixed 16mb it's kinda rough.

we need bigger partitions on a newer builder image, methinks
