Yes latest (11.6), might try old drivers that came with the card!

Wise ... it's not always that new drivers are best,

Two quotes for inspiration...

- the problem is coming from CMP and your video card corrupting the textures while they are being compressed and mipped. Turn off hardware accelerated compression in your CMP settings

- open your "Option" settings and turn your Texture Passes to maximum

Two brilliant ideas! Everything above 6 GB really makes Win 7 take off

Yes Win 7 is a future job, will cost more money and even more patience!!
Don't understand CMP, is this another Win 7 thing? If you mean CCC I removed it then rebooted and the problem is gone! Not sure where to go from here!
Edit:
Now this is is also strange, I downloaded the latest Trixx and ran GPU-Z, before the voltage in GPU-Z showed only .94 now it reflects the voltage shown in Trixx (1.150) surely this proves that the voltage can at least be set to this!

I just found out from Gigabyte that the core voltage is set at 1.150 and cannot be changed.

Myeah... is it really nescesary? Didn't know you were such an overclocker.

Running a few things overclocked myself, but voltages are all default.


I guess the voltage GPU-Z gave you previously was in 2D/power-saving.


btw upgrading RAM beyond 4GB won't make a lick of difference for gaming, not unless the OS is using over 2GB (in which case I'd say there's something wrong with your OS). Better to focus on the CPU if you feel like upgrading.

You MIGHT be able to change the core voltage by flashing a modified bios (RBE). Is potentially risky though and catastophic failure will void warrantee...

I've had a lot of luck overclocking at stock voltage - 950MHz on the core at stock; although I think 900MHz is more the norm. Definately gives a decent performance boost.

Thought about that too, but aparently the voltage regulator on it doesn't support it at all. Flashing a BIOS from a card with a different controller would likely brick it altogether.

Yes I've decided that I'm happy enough as it is, I was more upset with Gigabyte blocking it after they approved the review that influenced my decision to buy - it's the principal of the matter!!
Just doing some tweaking now, the only problem is I can't use the CCC as this causes DirectX problems in Trainz, so I'm using third party apps to do the job!

I've red that people tried that in BIOS with that Gigabyte 6850 card and didn't work and only managed to do harm then good...so it's not worth a risk.

that card has the core voltage locked, but if you ask me the last thing I want to temper with is the voltage of a GPU especially while still in warranty.

Reece,
could you post a screenshot of the CCC 3D panel with all the settings?
and have the sliders/settings put the way you've tried it with Trainz.

I don't have it installed anymore, I could disable the third party apps and reinstall CCC if you think it is worth it! I did set them all to application controlled or default settings. If it helps in the evaluation when I uninstalled it I checked and the devices CCC.exe and MOM.exe were removed from memory, I tried Trainz but fault was still there, I then rebooted and trainz worked!

No, it's Content Manager Plus for Trainz and is accessible via the Trainz start-up launch screen.


Note re. RAM... I've been through every combo from 256 MB up to 8 GB and can assure you, that each and every step up will make everything snappier!
So don't listen to Arclight!

I thought you must have been referring to something entirely different, I couldn't see anything relevant to Trainz Content Manager, I assume you have Trainz? The train showing the fault is actually the "Blue Comet".

In windows, multitasking. You know as well as I do that a game that will never use more than 2GB could never in a million years benefit from more than 4GB of RAM.

@ HunterICX, well it kept nagging at me so I decided to remove all third party apps and reinstall the CCC, without touching anything I ran the game and was still stuffed! So I went through the 3D settings changing and testing then I found it, or more so you found it! It was "Anti-Aliasing Mode" was set to "Multi-sample AA", I checked this by pressing Defaults and it slid back to "Performance" setting. I never deliberately set this so it was either from a third part app, accident, or register setting from previous install but I doubt that since I always remove old ATI references before installing, so there you go, at least it all works again.
Thanks Wim, and thanks to All for the superb help!
