Guide to running multiple GPU work units

[AlienIsGOD]

so any idea how a 6870 would fare with multiple work units? My rig should be together soon and i want to have my old rig set up to crunch 24/7 on the i5 2400/HD 6870 combo.

I don't think those drivers liked my oc of 1100 on the cards. That is the only thing I can think of....

1100 MHz should be a safe OC. I ran my at 1102 until 10 min ago with no other errors then the sync thing. Now it is 1125 (one Asus and one XFX) at auto fan. The Asus is still at 10% and 50 C. I just love that HS.

This talk makes me want to try to get my cards over 1000 core clocks. Before anything above that crashed, but I'm going to try again; perhaps on the new drivers I will have some better stability.

My 6870 Hawk is doing single wu's on a 1045T and the rig gets 12-15k ppd. You should be able to get at least 2 or 3 going at once and get 20-25k ppd. Watch the temps though 6xxx cards run hotter than 7xxx cards....

Also my 6850's are running one each and they get right at 10 to 12k ppd per card.

My 5770 get 8k ppd with 2 WU on it. You should put at least 2WU per card! You would do like 15K+ ppd per card...

6870 Sapphire with Dual X cooling before they named it as such. My 6870 never went hotter than 60C in BF3 so i pretty much expect the same temps from WCG on it.

My 6870 Hawk has the Twin Frozr III on it which is a little beefier than your cooler and it runs in the low 60's, which is 5-10C higher than the 7770/7870's I'm running and they have lower budget coolers.

In either case, yes they run hotter but nothing to really worry about...

I was actually thinking of doing that. Once I have my new main rig done ( ordered more parts today for it) Then this rig will be a dedicated crunching rig.

My gpu buffer is really getting loaded! Check your buffers gentlemen, we have a lot of crunching to do!
Edit: got my eighth star!!!

 

[ThE_MaD_ShOt]

I upped my buffer today on the 7850 rig. It added about 1.5k more units to my buffer.

We are talking about 7700s which are born as 1000 MHz GPUs. My 7970s are running at 1024 MHz. I had to put then next to each other so one is running hot (+65 C)....

I had one of mine doing the same (75C). A single 140mm fan in front of the cards brought it back down to the mid 50's

I already have a 120 mm fan laying on top of them. I decided to swap cards with another rigs cards since two 7700 doesn't produce much heat and hence would have less problem being placed next to each other but gave up since I got driver stops all the time with the 7700s when I swapped. I guess that I will swap the two 7970s around from time to time. The other (identical) one is running at 45 C. 20 degree difference is a lot.

I am actually thinking about selling my 6870 to grab a 7770 instead. The 7xxx series of cards crunch soooooooo much better than anything else.

I was getting the driver stops and crashes with my rig that has the 6850's in it. I disabled crossfire under Amd vision and the stops and crashes went away. I left the bridge connected to the cards so all I have to do is toggle on crossfire in the software when I need it.

Thank you for the advice but as far as I know Crossfire is of. I blame it on the ATI drivers in general. Before WGC opened up for GPU I was 100 % in the other camp and never had a driver problem. Now I have problems everyday. I think that I still have one PC (retired but just waiting for me to put in a NVIDIA GPU into it) that newer say a ATI driver. I might test it tomorrow.

Utility Update

What's new in Version 1.2.0?
Create the .xml file on desktop if BOINC is NOT installed in the default directory

Version 1.1.0

Spoiler

What's new in Version 1.1.0?
Added Windows XP support
Auto-detect if BOINC is running
Verifies if BOINC is installed in the default directory
Verifies if the .xml file was created successfully
Gives a suggestion if the file was not created
Verifies if the .xml file contains error
Tells you what is wrong if the file contains error
Corrected the bug where the utility would exit because of typing letters instead of numbers

The utility now support Windows XP/Vista/Server 2008/Server 2008 R2/7/Server 2012/8
Please note that server versions are reported as desktop (Server 2012 is reported as 8, etc).
Require .NET Framework 4
I may also add Windows 2000 support if someone asks for it!
Please report any bug!

Cool, that's a great utility you've put together!
Win2k support seems useless---I don't think that anyone would be running an OS that is now 14 years old on a GPU that supports WCG

 

[oldDirty]

Try the tool several times, only get one working gpu Wu @ 7950..Win7 boinc client up to date.

How long did you run it? Sometimes it needs to finish up a cpu task or two before it kicks in. You could also try:

- reboot
- expand the work buffer a little more (0.5 days or so)
- reset project (this should be a last resort)

 

[oldDirty]

Now boinc pass a very few CPU Wu last hours ago.
Anybody have the same Problem before?
Do i need change some settings in the manager?

What version of BOINC are you running? IIRC you need the 7.0.40+ version, not 7.0.28...
Can we see a screenshot of your BOINC manager and the text of the event log (Ctrl+Shift+E)?

That is what i see last minutes, i run the Beta before. Now it works, thx. solved.

Awesome!
Let us know if we can help you in any other manner

So are we going to see 100K per day (10 GPU units at the time)? You got an better CPU then me and I can do 95K in average.

I managed to duplicate t_ski yesterday by running the most productive host. I think that all of the 3x7970 rigs had an off day but still my little workshop open box rig did come out on top.

Edit: Bangkok Crunching Team, well it all goes in the same pot.
