Next on your list is to upgrade to Windows 8.1 I think that I will try that tonight and see if anything improves.

I don't know if your particular problem will improve but your overall "user experience" will. Win 8.1, with a few easy adjustments is a desktop OS.

Sounds about right :)

As I remember it, you had an AMD 7750 & NV8800 previously. If you still have the 7750, have you tried replacing the problem 650 with it? I think you've already swapped slots with the 650s, but have you tried matching a different card with one 650? If one 650 works fine with the other card but the other 650 doesn't, I'd consider returning the 650 that doesn't work with the other non-650. If both 650s work fine with the other card, you've entered the twilight zone.

I have decided to try your suggestion and replace 1 650 with my 7700. The 7700 is acting quite different than I remember it. I recall it taking 1 hour to complete 2 WUs. It has been running all evening, and hasn't finished a task yet.

AMD Radeon HD 7700 series (Capeverde) (1024MB) driver: 1.4.1848 OpenCL: 1.2

I installed the latest drivers, but can anyone think of what I might have forgotten to do to set the card up properly? I have it set up to run 2 WUs at a time, and after 90 minutes it was barely finished half of each. I read through my old posts, but I think I've done everything the way I had before, minus newer drivers.

Did you install the HD5 version of ATI MB7? That and having one free CPU core should be about all that's needed.
If you can install the version manually there's a slightly faster version here, Seti V7 for HD5/6/7

I believe I did, but I will try it again. Have 4 cores free (Gave up CPU crunching for now), so that shouldn't be it.

I am just not having any luck lately! But I do appreciate your response. Off I go to reinstall lunatics...

Since you mentioned new drivers, you might as well delete all the old binary .bin files from setiathome.berkeley.edu so new ones can be compiled. Delete every file ending in .bin, .bin_V6, .bin_V7, and .wisdom.

There was not many, but I think I got them all...

Now just to wait for a WU of the correct type.

Thanks again for your responses!

It seems that the same outcome from last night is happening tonight.

Extremely slow ATI WUs.

I'm wondering if I should reinstall the stock apps and see if they do any better.

Never thought I'd say it, but getting two newer Nvidia cards was the biggest mistake I've made yet for this poor dedicated cruncher!

What is the make and model of that motherboard?

Cheers.

Good question :) I'll have to try and see. However, the ATI card I am trying on it used to run 2WUs an hour, so it "used to" run pretty good on the motherboard.

Here is a completed ATI WU that took a very long time to complete.

This thread has gotten quite off topic from its original intent, and I apologize for that. It is now more of a series of musing by a confused cruncher, but thanks to anyone who is still commenting.

Does anyone see anything special about that task that would explain it taking so long?

Wiggo, I looked around at the motherboard but I am really unsure of the model of it. Any way to tell besides taking the computer apart to search for a model #? The documentation I had regarding this computer is long gone, unfortunately.

Does anyone see anything special about that task that would explain it taking so long?

Yes, it say:
Max clock frequency: 300Mhz

This page gives for Cape Verde GPUs 800-1100 Mhz
http://en.wikipedia.org/wiki/Radeon_HD_7000_Series#Radeon_HD_7700

See what SIV shows (about Mhz, temperature, V, ... ):

SIV will also show your motherboard model in the middle of the top line on main window.

Thanks very much Bill! I'll check out that software tonight when I get home.

From your knowledge, is the 300mhz a setting that can be tweaked?

Yes it can, e.g. with MSI Afterburner (works on all cards, not only MSI):

But first see if SIV show 300 MHz, at what GPU load % and other parameters

I'm not familiar with ATI cards, but if a similar speed was displayed for a task run on the NVidia card in the same machine, I'd assume that the card had entered a protective downclock state following an error - NV cards can recover to a low-power, low-speed state (only cleared by a power cycle), so that you can still use them as a display driver and see what you're doing while you troubleshoot.

I do note that you do have a very high rate of inconclusive validations from the NVidia card, plus a handful of invalid results and two errors.

That suggests that all is not happy with the computer is general: I would suggest that you treat the 300 MHz as an error report rather than a setting to be fine-tuned.

Power down, check for dust bunnies and clean as necessary, and keep an eye on temperatures and clock speeds as you power it back up.

Thanks Richard for the information. The high amount of inconclusives right now is from my experimentation with running two NVidia cards side by side. No matter what I do, with 2 NVIDIA cards, I get 25% inconclusives. The only way that I have found my machine to run 95%+ valid WU is with a single NVIDIA card.

I used to run this ATI card successfully before I decided to buy the NVIDIA 650's. Since I can't run the two 650s, I am running one while trying to get the ATI going again. Maybe too much info.

You very well may be right about some sort of error going on. Unfortunately though right now I don't have any clues pointing to what the errors could be. I will give it a good dustbunny cleaning though, that is never a bad idea :)

mherr...How much Ram does your computer have? Just curious, might not have anything to do with what is occurring with your computer at all. I've often wondered how much Ram is needed on the MB to make sure the GPUs run appropriately. Tried looking it up but no one seems to give a straight answer to that question. Anyone here have an idea if RAM on MB affects GPU performance?

This machine in question has 4GB. The times I have monitored the memory usage, it was never above 50%. But, there was also plenty of times where I was not monitoring it :)

Is it possible to upgrade the RAM? I seem to remember reading that with multiple GPUs (at least in game playing) that not enough ram caused the games to stall. Maybe there is something similar occurring when crunching? Maybe when 2 are running, it stalls out and give an error but 1 runs fine. Just a thought

Not with the 32-bit OS he's using as it only reads just over 3GB of the 4GB he has now.

Cheers.
