Mobility Radeon 64 bit

[cristipurdel]

I have a 4650 card on my laptop, and i cannot run folding on it. It says the drivers are not supported in Vista 64 bit. The drivers from the laptop manufacturer are no good also. The DNA drivers also don't work. I've cleaned the drivers with driver cleaner, but after I've installed the official drivers, gpu-z still sees the DNA drivers. The modtool from DH still doesn't support the 4000 series, and the latest stable from DNA still not good. Anybody has a workaround for this, or should I keep waiting?

I'm not a good one to ask about which drivers to use on laptop graphics subsystems, but you must have drivers that have CAL support, and the newer the better.

If your current drivers DO support CAL, then you probably need to add the command line parameter string: -forcegpu

It must be followed by one of the following: nvidia_g80, ati_r600, or ati_r700 since only those three architectures are supported -- in spite of the much larger variety of model numbers that we commonly use to describe our GPUs.

What do you know. It works.
Also this helped http://folding.stanford.edu/English/FAQ-ATI2#ntoc26
I also lowered the cpu usage with FLUSH_INTERVAL=64 at ~15% for one core on a T6400 @ 2.0 GHz.

Apparently the environmental variables don't work so well for vista 64, since I get a lot of EUEs.
Anybody managed to get a stable run on a mobility laptop vista/7 64 bit with low CPU utilization?

Apparently I managed to get back to folding in the last week or so on my laptop.

First of all, for the installation of the more recent drivers (the hp site had 8.12 I guess ) I used this http://www.driverheaven.net/driverheave ... ost1284030
Despite the fact that the catalyst uninstaller was a little bit old, and gave me some weird graphics (I just pushed yes), I presume you can skip this installation.
Also when I tried to manually install the drivers with the "have disk method" for me it didn't work, so I also install the drivers from the setup with CCC ("but MAKE SURE you DON'T install the drivers. only CCC"... on my laptop it worked )

Secondly, for the cal files in System32, this http://www.overclockingwiki.org/forums/ ... hp?p=65774 provides sufficient information. Now that I think about it, my laptop gave some errors while folding previously form two scenarios: 8.12 laptop drivers didn't had the cal files, or I used a too big number for FLUSH_INTERVAL 64..128

Third thing, regarding the environment variables, this viewtopic.php?f=51&t=10853#p106153 helped a lot. I just stick with FLUSH_INTERVAL=16, despite the fact that my gpu usage is at 85..90%, I just want to be stable enough (and a little bit cooler).
Also I use PStart launcher, and I can easily modify the environment variables in the properties menu.

Until now, I finished 10 projects with the above settings and had only 2 minor errors I think.

ATI MOBILITY 4650 @ 550/667
Vista 64 SP2
T6400 @ 2000
Catalyst 9.7 .0678

Did somebody tested the ati mobility drivers in win 7, because on ati's site, they say they are beta and official, but only for win 7?

P.S. Drivers Sweeper, CCleaner and Mobility Modder can be made portable with Universal Extractor

nope, AMD Catalyst 9.8 for Win7 is a no go also...

installed it on my laptop with Vista Ultimate x64 SP2 and HD4650, the client says not supported...

astrial> Did you use the -forcegpu flag described by bruce ?

[astrial]

juz added, it's now attempting to download the core...

however after reading cristiprudel's long post, i noticed that there's no CAL files in the System32 folder...

[toTOW]

I think they're in a different folder on 64 bits Windows

[astrial]

juz did a searh and nope, can't find any CAL files in the Windows folder...

downloading the Vista Catalyst for desktop Radeon now, going to use Mobility Modder and see how it goes...

[astrial]

still a no go...

CAL files found and copied into the GPU working folder after renaming...

forcegpu does not work also...

Right now I'm trying Win 7, and apparently everything is running smoothly.
In GPU-Z, atiumdag vers. is 8.14.10.0662 which is probably Catalyst 9.5 (didn't had to install any drivers, win 7 just found the drivers and installed it).
When I saw that I didn't had to install any drivers, I jumped on the console version. I deleted the atical**.dll and replaced them with atical**64.dll from System32 (vers. 6.14.10.283). In SysWOW64 there were the same version, but for the 32 bit version (only atical**.dll)

Same settings: FLUSH_INTERVAL = 16
Until now, only 2 projects finished, although I may see a time increase for 1% (right now is 10:22, in vista was afew seconds faster)

[cristipurdel]

I've installed the latest 'ati video upgrade' in Win 7, and GPU-Z shows that I have Catalyst 9.7
After deleting all the atical*.dll in the console client, everything is running smoothly.
For my 4650, FLUSH_INTERVAL = 32 uses the gpu around 98% for 511p projects, and I could probably go a little higher for the 384p projects, but I'm sticking with this value.

After a couple months of testing and optimizing the gpu client, my advice for Win 7 users, use the console client, delete any of the amdcal*.dll files inside, update your 'video drivers' and for setting the environmental variables, I use PStart (portable, can also set flags, no restart required)
