Latest drivers (NVidia and ATI)

[Urs Echternacht]

We need to locate place of failure. I've seen the same with windows Cat preview.
still unknown where exactly data start to differ between driver versions.
Please, post your findings in corresponding thread on AMD forum too.

Added my findings over there.

[Fredericx51]

I tried CAT 11.10, immediatly produced errors and driver crasht, so I strait went back with CAT 11.4.1332 ,
 last ATI 5870S GPUs WU ;

But this is older version and the problem is amount of CPU use when using GPUs and the latest driver, atleast above CAT 11.4?

[perryjay]

Well, I went back to driver 267.59. I have been getting some downclocks with the newest driver 285.62. I'm also getting some invalids with high pulse counts both in the AP and MB work. I can't swear it's the driver as I also started using the rescheduler again to move things around so that might have been causing the problems. I've also been watching some videos.  I'll see what happens with the older driver as it was working fine for me before updating the driver.

As always, I have my Intel E5400 dual with my GTS 450 slightly overclocked to 883/1766/1804 running one AP and one MB or two MBs at a time. (count set at .51/.49)

Oh, and I'm running 6.10.58 64bit  and x39e Lunatics along with Raistmer's open CL for NVIDIA R521.

[Mike]

I wouldn´t wonder perryjay.
I imagine nvidia is going thru the same issues AMD did month ago and still has.

[Frizz]

I just wonder why both companies have similar issues (well, at least they *look* similar) at the same time. Maybe it's because they already add support for the next architectures (Kepler and GCN) in their drivers - and break their old code.

[perryjay]

I don't know, I just went through a bunch of my pending APs on NVIDIA and it looks like I'm going to loose a lot of them. A few have completed okay but a whole bunch of them are showing 30 repetitive pulses. Sorry guys, I hope going back to the 267.59 driver will cure it.

[arkayn]

I keep my GTX460 on 266.58 for that reason.

[PatrickV2]

New NVidia 285.79 BETA drivers are out. Haven't tried 'em yet, since I see no real improvements for the games I'm playing.

Anyone here found any improvements for CUDA?

Regards, Patrick.

[Jason G]

Anyone here found any improvements for CUDA?

Those drivers are likely supporting Cuda 4.1 rc1 .  There are quite a lot of additions over Cuda 4.0 & 3.2, one supposedly being a rewritten compiler that generates better performing code, but it isn't released yet & there's a lot to wade through before I know if it'll help us.

[Raistmer]

BTW, what computation interfaces NV Tegra2-based devices are support?
There are tabletPCs running Android OS equipped with Tegra2. AFAIK no CUDA or OpenCL support, right?

Not sure yet.  Current specs list OpenGL-ES, and I believe there is a spec in the works for OpenCL-ES, but haven't looked into it much further than that.

    My GTX460 likes the  285.38 Beta better than anything before or since.

Are you running OpenCL AP work on yours?

[Mike]

Cat 11.11 is released.

      i haven't tried that yet. Would you suggest it and if so
what do i need to do ?
