different "geometries" of RAM

I take it you found the layout of ram `banks` like 2Rx4 and 4R4 on ram sticks shure do funky stuff if the board can`t take it

The board will take any of them, but if they're not all the same, it can't dual channel them etc.

Do you know what those things mean? For example, I have 16GB 2Rx4, also 16GB 4Rx8. Surely 4Rx8 is 4 times bigger than 2Rx4? It's twice as big in both dimensions. I would have expected a 2Rx8 and a 4Rx4 to be equal in size. Perhaps there are more chips on each. I can't be bothered looking.

I did look it up a while ago and each stick is internaly divided up into banks of chips for some purpose I don't remember
Had another look.
type this int search - "what does 4rx8 ram meaning"
this brings up a lot of stuff to do with how the memory controler addresses the memory chips and how they are phisicaly connected on each stick
A16GB stick is a 16GB stick however it is internaly wired,
older motherboards and domestic boards cant take the multi bank type`s for servers
Now I have a headache, time for some parotcetamol . . .

I assume this is the same thing as "high density memory" which was being sold very cheaply on Ebay about 10 years ago. I bought a metric tonne of it for 500 computers at work. Only half of them acknowledged its existence. The sellers often said things like "only suitable for high end gaming machines" as though it was some special kind of memory. In fact it was just much cheaper to make, or was found incompatible with so many MBs that it got sold off cheap. We had Dell machines at work, and Dell is notorious for being incompatible with everything. I used as much as I could then resold the rest.

Damnit Greg! You deleted your post while I was replying to it, and now mine has vanished!

The main points:

Doesn't make sense, you would think a drive access problem would return a file not found error, not a GPU error. I've like you only used C or C/E, so I don't know about D, but I'm sure someone must have done it and would have reported this bug.
Try making your new drive be F.
Or don't split install, just put it on the new drive only.

Problem solved and so freaking simple!
apparently data has to be stored in a folder on the drive rather than out on the drive itself

So maybe this also solves the M.2 problem?
I am on SATA now...so no idea

Ah! Good to know (although not so good for you, you've lost out on an M2). I'll report this as a bug to the programmers.

So if out in the open on the drive you lose the GPU, if in a folder on the drive then everything is fine.
Took me 2 weeks and a lot of hassle to figure that out, it was only after the error that I got a light bulb idea.
God, how annoying.

So if you get a M.2 then try this first if you get GPU errors.
I reported it in my thread on BOINC Forum.
Maybe someone there will notice as well.
The only guy helping me is a Dutch guy who has some RL issues taking priority.
Several other piped in at the start with all the usual stuff.
Anyway....bed time here..monday comes fast.

Programmer is asking if you have Boinc installed as a service?

On mine it`s
computer/F/ProgramData/BOINC/notices+projects+slots folders and all the other files, and F/Program Files/BOINC/locals+skins folders and the other files
is that what you ment by in a folder
I first created the `Program data` and `Program files` folders on the disk
Then installed boinc to the drive by changing the `advanced` settings , it did not like that because it created another folder named `ProgramData` different spelling.
I did not chose `F` that was the next available drive letter.
It does now seem an appropriate letter of the alphabet for it to use considering all the funky stuff it has done.

Tell programmer guy, BOINC was installed on its default settings, only change was where the data was stored.

So it was C: program files/BOINC

Then data was attempted to be installed as just D: (no folder) and after the errors D: Data (folder name) because bit was C: BOINC Data folder and E: BOINC Data folder.

But if it wants a folder, then why not say so during installation or in the startup log into?

It's weird that CPU will run with no folder but GPU requires a folder.

Have the person explain that!

I have mine in E:Program DataBoinc, which I created. I only noticed it was different when trying to copy configs between computers and kept getting path not found. The ones that had put it on C: themselves as the default had no space between program and data. A Microsoft bug. FFS, all the backslashes go away in this forum. I even tried the code tag but it still removed them!

Oops , I forgot about that , I was thinking in Linux // Vs
And so it duz I put two backslashes after the Vs to try it
I suppose it is seen as a part of the BB forum tags and so is hidden
Arrr :-) , but if you put fore in you get one \
so lets try ten \\ Hmm got two
Ok twenty backslashes \\\\\ I know I am being silly . . . .
Ok so I got five
Game over :-}

I have 49 gigs of memory and Python x 13 used up close to 65% of that memory and nothing else could run.
Then BOINC got a brain and sidelined a bunch and put SiDock x 5 into play. and I am down to 56% usage.

Such pigs of memory these Pythons.

Good grief..do I need 4 massive sticks of memory now? I just dropped a 150 on two big sticks. Plus 65 on a new 550GB drive (78% free) I think I might put a project limit of 12 tasks into play unless someone has a way of isolating Python with a code? I've put to much money into this computer now.

This may help - if it gets accepted someday:
https://github.com/BOINC/boinc/issues/4602
https://github.com/BOINC/boinc/pull/4603

Over the weekend I was running a permanent load of 29 VMs concurrently on a 32 core box with 128 GB RAM.
Disk I/O load - close to zero since /slots/ was mounted as tmpfs (similar to a ramdisk).
But the project admins would have to create a new app version with reduced limits and the modified vboxwrapper.

I hope differencing hard drive images support is coming soon.

Lightweight, I have 64GB in my main machine. 3 of my machines will take 128GB if necessary.

Weird, tags have square brackets, why is it trying to interpret backslashes? Boinc forums are the most screwed up I've ever seen.

Sounds like a brilliant suggestion. I hope they make it work.
