Dave Baker - 18 Aug 2009 15:27 GMT Bought a couple of 256mb sticks of PC133 sdram on Ebay last week to upgrade my antique 733mhz pentium to its maximum 512mb and sod's law it turned out to be ECC parity stuff for servers not desktop pcs. Strangely it does actually work but each stick is only recognised as 128mb so I'm still stuck at the 256mb total I was previously. If anyone has a very old, circa late 1990s to 2002ish pc, with any 256mb sticks of PC133 168pin unbuffered non-ECC sdram in it they might be chucking out I'd be interested.

Just looked through my store of 'bits that are too good to bin and might go on eBay' and found half-a-dozen 128Mb and 2 256Mb
Send me your snail mail address to jg@rescentcomputing.co.uk and I'll post them on.
I have no reason to believe that they are anything but good but I don't have a system I can test them in.
If you find they suit your needs then you can send whatever beer tokens you consider they are worth to you :)

Dave Baker - 19 Aug 2009 15:02 GMT Thanks for the offers JG and Peter. I'm more than happy to release a couple of beer tokens for anything that gets my feeble machine up to 512mb but don't want anyone to be out of pocket. I only bought the ram off ebay because no one else bid (no one else is daft enough to be using a pc that old I guess) so I got it for the minimum 99p plus the same again in postage. I can't imagine that ten year old ram types are in great demand but who knows. They want £25 a stick in the shops but I doubt if they sell any.
I'm still a bit puzzled why it actually works at all but only at half its nominal size. I downloaded the pdf file for the motherboard off the Intel site (D815EEA) and it says it can take either ECC or non ECC ram but it will will only run ECC in non ECC mode. In other pcs when I've tried ECC ram it doesn't work at all. Then there's the single sided, double sided ram issue but it says it should be able to cope with two sticks of double sided so I'm still puzzled. The ram that's in it now is all single sided - one stick of 128mb and two of 64mb. The ram I bought was double sided. Maybe it's a buffering issue and it really wants unbuffered ram like the manual says but I'm buggered if I actually know what that's all about.
The Crucial scan tool says I want 2 of these.
http://www.crucial.com/uk/store/mpartspecs.aspx?mtbpoid=40655AB0A5CA7304
Note that they have only 8 chips on each side rather than 9. The ones I bought have 9. Dividing by 3 seems to be a parity issue so clearly I want something that isn't divisible by 3. If you have anything that seems to fit the bill let me know.

You already have three rows and so it can only use one side of the double sided ram you bought. What happens if you remove one of the 64meg ones?

Reading it properly it only supports 4 rows at 133mhz so with your 5 rows it should see it but only run at 100mhz.
At least I got the parity bit right and that's something for me these days :-)

Nothing to do with being divisible by 3. I removed all of the existing chips before fitting the new ones. It has 3 ram slots which support a maximum of 4 rows of memory so you can populate all 3 with single sided, 1 with double sided and the other 2 with single or 2 rows with double sided and nothing in the third. That much is absolutely clear and simple to follow. The 2 new double sided chips didn't exceed the stated rules. I tried them in every slot and also one at a time but they always only registered as 128mb not 256mb. Clearly the machine is only recognising one side of each chip but why I'm not too sure. The parity, buffering or ECC status must be the reason.

I think the single sided one might be too high a component density but it's bloody hard to work out what this damn board will take. Crucial says it can use a maximum of 256mb per component and also a maximum of 4 rows (out of the 6 rows on the board) but it isn't clear if there's also a limit of 128mb per row i.e a 256mb stick must be double sided.

Some M/B memory configurations can be can be confusing. My brother bought a 1Gb module to upgrade his PC to the maximum of 2GB. It didn't work. After close inspection of the manual it turns out that the only configuration that works is a single 2G module.

I found a module recently in a server that supports ECC RAM where one module only tested to half its stated size. It looks like Peter's RAM is not suitable for your M/B. I have a couple of double sided DIMMs you can have. Send me your Address and I will test and send them to you.
If the 256M DIMMS don't work maybe you could bring it up to 384M by adding two 128M DIMMs. I have more of these.

I then tried a couple of 128M modules and they only registered 64M each. I brought them home to try them and the 128M modules registered 128M but the 256M modules still only registered 128M???? Much head scratching. I wonder if there is any link to the issues you are having.
Anyway, I have found a couple of 256M modules that register 256M in the BIOS so I will put them in the post tomorrow. They are not a matched pair but they should be OK.

The message I get from the BIOS when I boot up with these ECC chips in the pc is something along the lines of "Serial Presence Detect error - press enter to continue or F2 to enter setup". The SPD feature is apparently something on the memory chips that tells the BIOS what type and amount of RAM it is and it seems my two chips don't have it. They do however work happily at 128mb each. It is all very weird I agree. I don't recall having this much trouble matching RAM to any other pc.
I have however solved another problem which was after my last fresh install of XP I noticed Winrar taking forever to extract anything plus some stuttering and instability when I was playing avi files with VLC player. After much Googling it turned out my hard drive had defaulted to PIO mode rather than Ultra DMA mode. In PIO mode it seems the processor has to write everything to the hard drive one byte at a time and this slows things down by a factor or 4 or so. To check go to Control Panel, System, Hardware, Device Manager and check that the primary and/or secondary IDE controllers are in UDMA mode. If not then uninstall the controller and reboot and hopefully it will get re-installed properly.
Also during that Googling session I now find out that IDE cables have moved on from the old 40 core ones I've been transferring from machine to machine for years and that for modern hard drives I really need 80 core stuff to get the faster UDMA modes. Currently I'm in mode 2 but the drive could probably go faster. It never bloody ends.

For modern hard drives you'll need a SATA cable, which is a single shielded cable, not a parallel cable.
I used to know much about memory compatibility, but I've forgotten it all - it's so last millennium.

Essentially correct but new IDE drives are still available and 80 wire cables are still included with new motherboards from all the major manufacturers.
SATA has still not gained full status with case manufacturers who are still supplyig PSUs with only Molex connections, requiring a conversion cable where SATA drives are specified.

Possibly because you need some sort of ide/PATA for optical drives anyway...
Guessing, they probably don't make slow IDE chips any more, and need to use ide133 chips, so supplying an 80 wire cable, as opposed to a 40-wire cable, to a single IDE header, which allows a single PATA drive functionality plus temporary connection of an old PATA dive, is a cheap investment in backwards connectivity - besides, don't some optical drives need 80-wire cables anyway?
However I sort-of agree, eg you can still buy mobos which don't have SATA - though I wouldn't recommend it.
> SATA has still not gained full status with case manufacturers who are > still supplyig PSUs with only Molex connections, requiring a conversion > cable where SATA drives are specified. Yeah, that's strange, but adapters are about 50p, and sometimes SATA drives come with them. Early SATA drives had Molexes iirc.

This lowers crosstalk between the wires, so faster speeds can be used.
The blue connector also connects pin 34 to earth so as to let the devices know an 80-wire cable is in use, and it doesn't connect pin 34 to wire 34; and the grey connector doesn't connect pin 28 to wire 28, for master/slave cable select.

It's crashing for England now. Firefox going down and refusing to restart, Utorrent doing the same.

For now I'm trying to download something before AOL stop all p2p activity which they do every day between about 5pm and 11pm. After 5pm I'll have a really good play and see if I can at least get one 256mb stick running reliably alongside the existing 128mb and one of the two 64mb ones I had in there. That at least will give me 448mb which would be a big improvement.
I've already lost half the day dicking around with AOL yet again trying to find out why my supposed line upgrade to "up to 8mbps" is still capped at exactly the same 2mbps it always has been for the last 8 years. They keep telling me they've put the upgrade through 2 weeks ago but I think I'm being told porkies because even if I can't get the full 8mb it would surely have altered somewhat from the exact same 2272kbps it's showing me in the router diagnostics. It's like a slow and painful death making repeated phone calls to them and going through the same crap time after time with different people though.
"Have you fitted a filter in the phone socket?" No it's working by magic like it has done since I joined AOL.
"Have you plugged in the yellow router cable to your ethernet card?" Do you think the f.cking thing would work at all if I hadn't???

Right, well one of the 256mb sticks was definitely not working. I fairly quickly got a spontaneous reboot with just that one in and then later an actual BSOD with dire warnings to remove any recently fitted hardware. Never had one of those before. I didn't realise they actually were blue. The second stick seems to be ok and I couldn't get it to crash with just that in on its own. I did get one crash when I added the old 128mb stick to it but I moved that to the third slot instead of the second and added one of my 64mb sticks in the second and it's been working ok all night. Maybe something hadn't been seated perfectly. So I'm up to 448mb out of the possible 512mb which is not too bad.
So my choices seeing as it's a max of 512mb and I can only populate 4 rows out of the 6 on the MB (3 double sided slots) are to find another good double sided 256mb pc133 stick or another single sided 128mb pc133 stick to add to the existing 128mb single sided one in there and remove the single sided 64mb pc100 one in there which will be slowing the whole lot to 100 anyway - or just to leave it well alone now.

Well it's been rock steady for 30 plus hours now without a reboot with 1 x 256mb + 1 x128mb + 1 x 64mb (448mb) chips in it. To be honest trying to get the last 64mb in there to bring it up to the full 512mb would be gilding the lily - or maybe trying to make a silk purse out of a sow's ear given how old and crappy this pc is. I'm well happy as it stands. I'm also more than happy to donate a couple of beer tokens to try a final 128mb PC133 single sided chip alongside the existing one just to prove a point.
The basic Intel motherboard and ancilliaries are so stable on this old thing I think it might last for ever and it surely does everything I really need to such an acceptable standard and speed that I could probably live with it forever. Only if I were to want to do highly intensive cpu tasks like video editing or gaming would I really need a modern machine. For web surfing and general downloading it's fast enough.
I suppose the car equivalent would be bangernomics. Running a 10 year old clunker so that someone else has paid for the depreciation without radically reducing the utility of the machine. I did used to be a fan of that too until got my Focus and decided that spending your time underneath old cars fixing them was not an ideal way to spend my time. At least fixing pc's can be done indoors, in the warm and dry, and without ruining your back lifting things. Swapping RAM chips is not so onerous.

Your comment on cars bring back a memories of changing the clutch on my Cortina Estate. This was done in the street with wife inside the car helping with a rope a bit of wood to support the gearbox. A short time later I was in the Ford garage for something else and saw a sign up offering a replacement clutch job for about the same price as I had paid for the parts. Still limping with the kick I gave myself.

Cheers Archie :) It's been fine for over 2 days now on the chips currently in it btw so at least my baseline is now a minimum of 448mb. Just to remind you the 128 sticks need to be single sided i.e. only having chips on one side of the board or I'll exceed my 4 rows limit if they have to go in along with a double sided 256mb stick.

Still limping with the kick I gave myself. I remember doing both the engine and gearbox on my Marina when I was about 20, outside on a gravel track, no engine hoist and no help and no real fears about managing it. I seem to recall lowering the engine to the ground once I'd got the mounts off then jacking the car as high as I could get it and dragging it out from underneath. Then there was some faffing about with me on my back lowering the box onto my chest and sliding it off me sideways. I have no memory at all of how I got them back in though but clearly I must have done. Just doing a set of brake pads 30 years later is enough to ruin my day. I'm too old for all this crap now.

Although neither the manual or the Crucial website were very clear about it the new single sided 256mb chip works fine alongside the first double sided 256mb chip you sent so apparently there wasn't a limit of 128mb per row. So that's me up to 512mb and it's been running happily for a day now. I did cheekily try adding another 128mb chip in the 3rd slot but it only counted up to 512mb as the manual said it would. I'd upgraded to the latest BIOS I could find on the Intel website and was rather hoping that might have got round the original memory limit but fraid not. Anyway 512mb is plenty for XP and the stuff I use it for. If one of the 256mb chips goes down I also have the backup of two 128mb ones to swap in instead which is nice.
It's weird thinking back to my first pc, an Amstrad 1512 which I bought in 1987 and which still works perfectly btw, which also has 512 of ram - except it's 512kb not mb. I vaguely recall paying a small fortune to upgrade it to 640kb from 512kb and I paid another £300 for a 20mb (yes mb not gb) hard disk which back then was a serious amount of money. From memory it ran at 8mHz and this one runs at 733mHz (which is still pathetic by today's standards) so with 100 times faster processor and 1000 times more memory where have we actually got to? I still use the same old Dos spreadsheet I did back then because I never got round to really learning Excel. Most applications back then came on a single floppy diskette and did everything you really needed. I've never really understood why modern applications need 100mb of disk space but do bugger all extra compared to things that were written into a few hundred kb 20 years ago. Oh and beer only cost a few pence a pint and the bread tasted better and my back didn't ache and my eyes could focus at 6 inches instead of 12. Grumble moan.
By sheer coincidence someone was helping me clear out the spare room on Friday and came across a bunch of IDE cables of which one was an 80 strand item which I now realise actually was the one I'd had installed in my previous pc. It's grey not white like all the other cables and I now clearly remember using it. Not knowing the difference it made I must have swapped the disk into this current pc using an older 40 strand cable that would probably already have been inside it. So anyway I slapped that in instead and my hard disk says it's now running in UDMA mode 6 instead of mode 2 although to be honest I can't actually tell it's going any faster during file transfers. It must be doing summat though.
I think that's everything I can do to make this old beast run as fast as possible so hopefully after so much buggering about the motherboard or cpu or power supply won't now suddenly decide to call it a day and put me back to square one. If it keeps working I reckon it'll do me for a goodly while.
I now owe someone a favour in return to balance my karma and keep the world turning smoothly on its axis.
