Merge same PC with different Boinc versions

(moderation:
Why can't I merge the same computer with 2 different BOINC versions? Nothing else is different because it's the same PC. Can someone at Einstein merge them for me? It's name is Windows-7-PC.

Probably because both hosts still have tasks showing in the online database. Just wait until they are all deleted for the hostID you don't want to keep. At that time you should be able to merge that host with the one you want to keep.

I still can't merge them

I still can't merge them because I replaced one off the GPU's. It doesn't have any Einstein work on it.
Can someone at Einstein merge them for me? It's name is Windows-7-PC.
Edit: I replaced a GTX-570 with a HD6950, but it shows up as having 2 GTX-550TI's, which it hadn't. It had one GTX-550TI and a GTX-570. So much for detecting GPU's correctly.
Same goes for my new PC (Mellowman, Core i7 2600K detecting 2 Nvidia GTX-570's, while in fact one is a GTX-570 and the other one is a GTX-560TI-448. This seems a problem on the other project too, so I'm not sure what/where the root of the problem is.

It does have work associated with it. Here are the tasks still awaiting deletion. You will not be able to merge it until these three have disappeared. That will take at least another 6 days.
Nobody else but you can see the actual host names that you have allotted to your machines. If you want to refer to a particular machine you should provide a link to its hostID. That way anyone trying to answer a question about a particular host doesn't have to jump through hoops and end up guessing. I assume we are discussing hostID 4690953? You are the only person who can attempt the merge. I'm guessing you will be able to do this even though there may be differences in the GPU hardware, but only when the online database shows no tasks. If the merge is still being denied at that time, you should stop being concerned about it since, after 30 days of inactivity, it will drop out of sight unless you use the extra link to see all hosts (including the inactive ones). You already have a couple of extra hosts in that category anyway. There's no real point in worrying about a merge since there is zero credit attached to this hostID that you can recover.
EDIT: I just had a closer look at the hostID I linked to above. The details page shows no credit and a creation date of 14th Feb. At the bottom of the page you can see a link to the 3 tasks still in the database. When you look at those 3 tasks they all predate the creation date of this host and one of them was awarded 500 credits. Looks like this host had a prior life as something else. Maybe you are doing something weird when you make hardware changes and this leads to the creation of new hostIDs?
EDIT2: I've just seen your post in the other thread about BAM. Perhaps that's the problem. I've never used it so have no experience.
Cheers,
Gary.
RE: Nobody else but you can

Yes where talking about hostID 4690953.
Even when the tasks are gone I won't be able to merge them because it's incompatible. I don't think having those 3 tasks assigned to them are the problem.
I want to have as less hosts as I can. If I could remove the host from 5+ years ago I would. And the only thing that changed in the host I want to merge is 1 of the GPU cards. And I know someone from the project could merge or remove my host from the database, including my old hosts.

I know that some years ago I was able to merge hosts that were physically different, as long as all tasks had disappeared from the database. Maybe that has now changed with newer versions of the back-end code. I haven't attempted a merge in quite a while.
Sure, with time and effort by the Devs, a manual intervention (with associated risks) would be possible. But unless you can demonstrate how wasting time for a purely cosmetic effect would somehow benefit the project, it's very unlikely to happen. Particularly at the moment with the transition to a new GW run and the release of the OpenCL app looming on the horizon. And if your request was granted, wouldn't that just unleash a horde of others wanting the same special treatment?
If this is really important in your opinion, you should make a feature request to the BOINC Devs - where this belongs. They would be the ones to add this sort of functionality to BOINC. I suspect they may be unwilling to allow users to remove redundant hosts automatically because of the potential for error or abuse.

Gary.

But you can!
As long as the task list of a host is empty, it can be deleted using the "remove" link on its datails page. And since your credits are linked to your account and not to the individual hosts, nothing would be lost.

RE: But you can! As long

Already deleted 2 hosts. Thank you very much Gundolf.
Gruss,

Well there you go!! Thank you Gundolf.
When the OP said so emphatically that you couldn't delete hosts, I just believed him and didn't even bother to check. More fool me!!
I've never wanted to delete any of my old hosts so I can't remember ever seeing the 'delete' link. I don't think it's been there all along. Perhaps it has and I'm just getting too old :-). I seem to recall in the old days people commenting about not being able to delete old hosts so I just assumed it was still the case.
I've always wanted to keep all my old host details because it's a very good record of my full crunching history. I can see exactly when I added certain groups of hosts and when I retired them from service and how much credit each one accumulated in its lifetime. It's interesting how low the credit rates were for hosts I had when the project first started. This host (92625) joined in March 2005 and was shut down around 6 months later. It only accumulated a small amount of credit in that time (<12K). On the other hand, this host (12594) was my first host to join the project and it's still crunching today. It's interesting to see that there were around 80K hosts added to the project between 10 Feb and 24 Mar 2005, just after the project opened its doors.
That first host (12594) has been running 24/7 for 7 years now. It's significantly overclocked and virtually all of it is original. The graphics card has had its swollen caps replaced and the PSU has had quite a few fan re-oils. It's one of the relatively few machines where I've had to replace the HDD. I have another virtually identical machine (same vintage) that is still on its original HDD. They've been such faithful workhorses that I don't have the heart to shut them down :-). They've run under adverse conditions (overclocked, over-volted, relatively high temperatures) for most of their life and they still soldier on. How could you shut them down :-).
Cheers,
Gary.
