They made changes to updating/refills for 7.X.X, and has resulted in different behaviour than (generally) in 6.X.X.

Basicly, with 7.X.X perceptions need to shift a little. Refills are more strictly controlled by the software, and less scope for manual downloads accumulating large caches. MW has its own limiter of course - 40 per GPU - but that still is caught under the whole overarching refill mechanism in 7.X.X

It will tend to run down cache (not always, just beaware it can leave it somewhat late!) until the last minute, and then refill. So, at the least sit back and let it do it thing, dont apply expectations of 6.X.X behaviour, it will not happen. The other change behaviourily, is - by in large - it now tends to download one or two WU at a time, not a big wack of them at once (MWs are short so you get lots of those in one go). Again, dont try to fight it (you'll lose rofl), let it do its thing. For example a dry machine on startup left overnight is rewarded with a full cache when you get up :)

There are still problems with aspects of the work fetch, but take on board the two behavioural changes above, as they are the most misunderstood, and nothing is wrong as such, the software is working "as designed" - just that its designed differently in V7.X.X

Hello,

I see now MW is using 0.98 CPU + 1 ATI, last week it was only 0.45 CPU.
Has something changed?

I run both a GTX470 and AMD6970 in the same machine. I use the nvidia for SETI(or others when not working) and the AMD for MW. However with the new opencl WU's they are getting assigned to the nvidia card and the 6970 sits idle. Is there a way to not download the opencl wu's or is there another way to solve this issue?

I delayed switching one of my machines over after reading about this but today took the plunge, upgraded the ATI drivers to 12.1 (Win7-64) and switched MW to use the automatic open_cl app. I'm using BOINC 6.12.43 and it works fine, running MW on the HD5870 and HD4770 cards while crunching PG on the GTX460. So far no hitches at all.

In some cases the stderr from BOINC is truncated or missing completely. I think I mostly fixed the problem for future updates

There is a new Version of the ASUS GPU Tweak Utility out - ASUS GPU Tweak V2.0.3, it is very good, and well worth a download. The link below is for the utility on 7970 cards. It may work on other cards despite the title on the main screen, I have no idea.

They have also folded into it GPU-Z. The result is a neat collection of tools, combining some of the Afterburner and GPU-Z functionality. The tool set is not as extensive as Afterburner, but its close .... real nice. Not had a chance to test thoroughly yet, but so far so good.

Thanks for that. I didn't know my system was hidden. How do I unhide it? I'm off-line a lot as I have to use a dongle at the moment due to no phone line.
Cheers. Paul

Can anyone tell me why over half of my large Milkyway@home v0.88 uploads have validate errors? They are 21, 28 and 42 thousand runtimes each so its rather disappointing to see them fail like that. Thanks.

In the users pc's over there it now says: "CAL Tahiti (3072MB) driver: 1.4.1658" for his gpu!

Sure is good to have someone (else) on the bleeding edge :)

I dont mind the bleeding bit ...... its hemorrhaging that gets tedious .... I leave the latter to extreme overclock lunatics, and those insane freaks who play with LN2.
I have never understood the attraction of the latter .... its so freakin dangerous its unreal, they are mental, its the only conclusion I can come up with :) Regards Zy

It blue screened after my last post

Whether they will release for XP is anybodys guess

What I'm doing:
I've got the DVI input of my monitor hooked up to the Sandy Bridge GPU and running all normal stuff, videos, light games etc. The ATI is connected to the VGA port (don't have a display port cable..), so windows keeps it active, and is crunching. I'm only disturbing it for demanding games.. occasionally.

The problem:
If I want to play a game on the ATI all I'd have to do is stop BOINC GPU and start it, Virtu will push the output to the IGP. However, I also have to adjust the clocks: core down, memory up. And this is what's not working: in my standard config (IGP @ DVI as main display) I can't set the clocks on the ATI. ATI Tray Tools doesn't find the card (says no ATI present), the MSI Tool crashes, Trixx seems to work but doesn't actually change anything.

What I do now is switching the primary desktop, switching to the VGA input on my screen, changing the clocks, replacing the primary desktop and switching back to DVI. Rather cumbersome.. Any further ideas? Best regards, MrS

Other projects are utilizing my 6870 just fine just so ya know. Thanks for the option to be able to help in this project! :) Also let me know if I just need to wait for a new Milkyway update too.

I'm also using ATI Tray Tool because it's about the only tool which lets me downclock as far as I want. And I'm usually driving my display from the Intel GPU integrated into the CPU (no screen lag), unfortunately ATI Tray Tools doesn't detect my AMD at all this way. Are there any other tool which can do both, downclock (~50%) and detect / set all GPUs? MrS

They are 28nm cards and therefore far far more power efficient than previous series by an order of magnitude in comparison to what has been normal in cards so far.

That would be a factor of 10. A bit generous ;)
Might be that high if GCN is a huge improvement over VLIW for some app (probably GPUGrid), but not for something which runs well on VLIW (e.g. MW, Collatz, Moo).

But in Afterburner you can't downclock the RAM by much.. as it would be efficient for MW. I even asked them some time ago to somehow let people adjust the lower clock limit, to make their tool more useful. They said, it wouldn't be in the spirit of Afterburner.. MrS
