I had exactly the same

I had exactly the same problems as WB8ILI on my computer with an Asus graphic card GTX660 on a motherboard Asus M5A88V with AMD CPU. After plugging this graphic card into a new x79 motherboard no issues arise at all. Now it is doing a really good job in combination with this board. I guess (!) a PCIe 3.0 card plugged into older PCIe 2.0 boards cannot be fed with data quick enough which eventually causes problems.

Thanks Alintope. That makes sense to me. While the motherboard is new (recently purchased) it is a PCIe 2.0 board. There must be something about Einstein workunits (as opposed to Milkyway and SETI workunits) that expose a limitation of my motherboard/GPU combination.

I have seen something about E@H in the forums. Sorry can't link ya at the moment.

If I remember right only E@H has this problem: CPU to GPU and the lanes it has or it is that pcie 3 to pcie2 gets slowed down. This sounds like that could be it but not for sure. Sorry it's been awhile internet was down for the past week and this weekend I will be moving but as soon as I can I will try to find out more for ya.

The one thing I would do is

The one thing I would do is add more Ram to your host since 2GB ram on your quad-core is really not going to help things run smoothly.

You would probably not have this problem if you just added 4GB and that is a quick,easy,and cheap way to see how it does make the difference.

Having that 2GB reminds me of the old days running a PIII 500 here.

As far as the 660.......do you use GPU-Z to check the temp and clocks?

I have used speed fan in the past but for these GPU tasks and upgrading several of my hosts in the last year with the 660Ti superclocked and 550Ti's OC's it does a better job.

And I still use XP Pro on a few of them with no problems.

My GeForce 660Ti runs from 63C to 68C depending on the room temps here and I don't use any fancy cooling (just have the side panel removed and a 20in fan blowing across the 3 that I use for Einstein cuda's) and they also run T4T X2 and a Gamma Ray at the same time with no problems.

Do you know which DDR version your Ram is?

I found out that is was much cheaper and easier it was to upgrade mine that used the DDR3 and my older ones that needed DDR2 and DDR I was lucky to find some in my stash since they cost a bit more and that is just adding the DDR2 2GB version.

Good luck

Ya know ya could be on to something here. I didn't really look at the low amount of ram because of running XP. If WB8ILI was running vista or 7 or even 8 I would have first thought of more ram. In my exp. with XP you can get by with doing alot on less ram but I don't have alot of exp. with Boinc yet.

The amount and speed of the ram could be an issue here. Thanks MAGIC for pointing that out. I remember my first computer had only 4kb ram and if I remember right the processor was like 0.895 MHz "I would have to look it up to be sure" lol we have come along way since then. Tandy TRS-80 Color Computer 1 then a bit later I got the newer Color Computer 2 that was alittle bit faster.

Not sure what world you come from, but here a PIII 500 was released in 1999, and memory amounts (for sale) then were 32, 64 and 128MB PC-100 DIMMs, at prices ranging from $46.- to $300.50

The first time you could probably and reliably put 2GB in there was at the earliest 2002, when 512MB PC-133 DIMMs became available for $99.-

The better PC-3200 and DDR2 memory available from 2005 wasn't going to fit on the motherboard of your PIII 500, as these were 184 pin DIMMs and PC-100/PC-133 only 168 pin DIMMs.

:-D

Thanks Magic for the

Thanks Magic for the suggestions.

Memory: I have a single module of DDR3 PC8500 (1600 MHz). I sort of agree with Nobody316 about the amount of memory. The computer is just used for BOINC and has minimal bloatware. When running 4 non-GPU SETI WU's and one GPU SETI WU, I have 1.3 GB free memory. With 4 non-GPU Milkyway WU's and 2 GPU Milkyway WU's, I have 1.4 GB free memory. I am not sure more memory would help. Unfortunately, I can't determine the Einstein numbers because the computer screen locks up about 10 seconds after the GPU WU Einstein starts.

GPU-Z: Yes I use GPU-Z. The temp is 55C-58C depending on the room temp. GPU Core Clock shows 1058 MHz and the GPU Memory Clock shows 1502 MHz. These are the factory default (I didn't change them).

I used EGA Precision X to increase the fan speed to its max, which for some reason is 74%. This lowered the GPU temp form mid to high 60C to mid to high 50C.

My GPU card is an EVGA GeForce GTX 660 02G-P4-2660-KR Video Card - 2GB GDDR5 which is NOT of the the "superclocked" models.

As I wrote before, there is some "weakness" in my setup (motherboard, chipset, memory, drivers, or ?) that is not an issue with SETI or Milkyway GPU WU's, but is fatal with Einstein GPU WU's.

Well yes I know all of that Jord

I said it "reminded" me of the early days here and I suppose I could have added Seti Classic (but then I stopped running those when I started here over 8 years ago with that PIII 500 with Windows 98SE which I made my own disc with XP Pro and updated it to that)

And slowly moved up the list of processors and Ram versions as I mentioned.

I still have the one in my parts stash along with a few others that I have used here over the years.

I actually had problems with the one I added the EVGA GeForce GTX 660Ti SC'd that was freezing up every time I was just checking it's tasks and after I updated the ram to 12 GB it stopped having that problem.

http://einsteinathome.org/host/4109993

Which is where I found a couple DDR2's for the couple hosts I still use here and one is also updated with the 750watt PSU and the 550Ti OC'd

Most of mine are still on my list except I see the old AMD 1600 is not there for some reason.

But anyway as I said think WB8 would be better off adding another 4GB ram to his with the 660 since 2GB ram is something you don't see much these days and even my oldest one still running here has DDR2 3GB that it came with and I will upgrade that once I find a DDR2 2GB in a parts stash since they cost too much these days.

WB8ILI just to ask as you

WB8ILI just to ask as you don't have listed as far as I can see. What is your power supply. Name and watts. This could also be something to look in too. Do note just because a power supply says 600 watts does not mean it's really 600 watts or 600 watts could be the max. Over all system temp could have an effect as well " not just processor or GPU temps but all temps even the power supply and home temp" I hope you get it fixed soon no matter what it is but none the less I will have to check back some time next week. I am shutting down the desktop to be packed for moving this weekend. See ya next week some time and hopefully ya will have good news.

Magic and Nobody316 - I

Magic and Nobody316 -

I bought a new power supply with the GTX 660. It a Ultra LSP 650 watt.

The quad core CPU is running at a cool 47C as I write this with 4 CPU WU's and one GPU WU running.

I ordered another 4GB of memory. It only cost 1/2 of what it costs to take my wife out for dinner so I figured that was a good deal.

I will report back after I install it and try Einstein again.
