Well I know that different revisions will use cards differently. For example, when I had two video cards with mis-matched shader counts I had much better performance with the 178.24 driver than any of the 18x.xx drivers, albeit at the expense of CPU load. 185.20 is actually a much older driver, dating back to early january as opposed to 182.08 which came out in early march or something. It's possible that 185.20 managed the cards resources differently, and for WU's with the on/off behavior it could be causing certain cards to spend less time switched off.

Hazzard> I get a connection timeout ... could you summarize ?

AZBradon> that's not logical ... 185.20 should be newer than 182.02 ... which is also newer than 178.24.

RU_Hil reported this in the P5902 thread. No mention of where he got the drivers.

I don't believe it, seems too good to be true. Are the scientific results accurate? The 185.20 is a couple months old, unless they keep putting newer versions of the same version.

I might give it a try ... they're available on http://www.laptopvideo2go.com/drivers for all windows version (I only have XP 32 bits).

Does this boost affect only p590x WU (core 14) or does it apply to other WUs too ?

I'm going to try the driver on Linux x86_64. I found a Link to it on the Nvidia forums :mrgreen:

toTOW, that is ONLY true for WHQL drivers. Those 185.20 drivers were never released to the public, they were internal use only drivers that got leaked to the public.

See for yourself:

http://www.techpowerup.com/downloads/Drivers/NVIDIA/

The 185.20 drivers were made available Jan 2nd, 2009. They are 2 months older than the current WHQL drivers.

Look, even Nvidia's driver naming scheme doesn't make sense!

Now that I look back at things... were these the drivers where people thought they saw references to GT216?

The only beta I can find for Linux is 185.13.

Do you have a link for 185.20?

Some fast results for people:

Running Vista 64, single GTX280: 13k PPD from single GPU, project 5903

Step Time Pre-185 Driver: About 3 minutes per step (around 7.5k PPD)
[22:45:52] Completed 12%
[22:49:04] Completed 13%
[22:52:08] Completed 14%

Step Time post-185 install: Under 2 minutes per step (13k PP)
[23:10:50] Completed 17%
[23:12:43] Completed 18%
[23:14:36] Completed 19%

So before I waste time installing it on my XP-32 system, has anyone seen this jump in points on any operating system other than Vista/7 64-bit?

I confirm an increase from ~6400 to 10150 PPD on a Geforce 8800 GTS 512 MB with a 5903 work unit.

2D drawing lag in vista x64 is slightly worse with these drivers.

Also, the squealing sound produced by the card has changed; it sounds more flanged, and the durations between have decreased.
