7800 GS OC lock-ups

[Eagler]

thanks - I changed that setting at lunch and did not have an issue on the couple of sorties I was able to squeeze in ..

so you don't have anything loaded in video memory?

thanks again

No - nothing loaded in video memory, with 2Gbs I can load all into system memory.

Skuzzy must have forgot about the PCI latency timer setting, I mentioned it to him when talking to him after I solved my problem.

Glad it worked for you.

Yes!!!

I spent four hours today trying to get my 7800GS to work with Aces High. I called HiTech and EVGA the manufacturer of my video card and spent lots of time on the web looking for a solution.  

I was told to 'roll back' to the 80.xx series drivers to effect a stable situation.  Didn't work.  I was told to get a bigger power supply.  Didn't work.  I was told to uninstall any other trace of other drivers.  Didn't work.  I was still getting hard lockups.  I mean I had to hit the reset button to loose the strong hold on my machine.  Then, I came across this post.  

I downloaded and installed the 3Dguru Driver for the card, and I was able to play the game without a single lockup.  But I encountered a new problem, and that was the screen would go black and I couldn't recover the system without again rebooting.  So, I recalled that during the installation of the 3dguru driver, that there was an option for people who were had 'compatibility issues'. I reinstalled the 3dguru drivers and selected the option for 'compatibility issues' and smooth operations.

It's ashame that NVidia can't make a driver that is compatible with the games that we buy the graphics cards for.

I hope this helps you!

Uhmm,..not the 80.xx drivers, but the 8x.xx drivers.  I think the last ones were the 85.xx series.  I have not had any reports of those drivers failing to work with the 78xx series cards.

The 9x.xx series of drivers are absolutely horrible.

And you did need a new power supply.  Whether it would correct the problem or not, your supply was being overloaded and would have failed badly soon.

Thank you Skuzzy for the clarification.  I should have said 8x.xx vice 80.xx for clairty, and I'm sure that I needed a new power supply.  My printer became intermittent after installing the video card, so that definitely was something that I missed.  (Side note: 575watt power supply only cost $40)

My case may be special or it may be common.  I did try two different 8x.xx drivers that did not work for me.  The ironic thing is that my video card and 9x.xx drivers did work in MSFlight Sim X.  I don't know why it would work there and not in Aces High.

Again, I hope this will be helpful to someone else and save the time and aggrevation that I encountered.

Flyhard!

well this thread is real interesting for me.  

I've had my fair share of problems and what eagler describes is exactly what happens to my system running a 8800gts

whether it be AH or BF2  the black screen is exactly what happens in BF2,

I will try these recommendations from kev and skuzzy and report back.  My only problem is i have to use the 9xxx drivers as the card is new.

to update my own thread see my other thread here:
http://forums.hitechcreations.com/forums/showthread.php?s=&threadid=176566

it turned out I had a very dirty heatsink/fan on the cpu and my ps was borderline. Changing out the ps and switching the cpu heatsink/fan to a bigger and clean one stablized my system.

Ok I've made progress too  

Kev You beauty!!!!

seems like the 64 change to 128 in the mobo settings has done the trick.

Played BF2 with and without AA  for 30 minutes a piece  (was crashing every 5 mins before.

Kev do you know what that setting actually does??

Going to try AH now.

I didn't really forget about it.  It is one of those things I cannot generally recommend changing as I have no way of knowing how it will effect other motherboards and how they implement the various chipset options.

As I recall, there are three controlling PCI latency variables, which are used to shape the final latency value.  Not all motherboards/BIOS's expose all three.  Some only expose one, others expose two of them.

Ok after BF2 running sweet I tried AH everything seemed ok feast your eyes on these screenshots.  The second pic on the boxes in the hangar have fat pigs with wings on them.

This is with hi res pack 1024, no pre loaded skins/textures, unlimited frames, 1024 resolution.

'If' I remember correctly -

It sets how long each device can hold the bus, or something like that.
Modern video cards are fairly bus hungry.

Bit more on it here -

Oh just FYI - Another fix is to disable the hardware vertex processing in the video options, but the PCI latency setting is a much better option.

There is even a GUI utility around that will let you modify the default PCI latency value of your video card and you can then set the bus back to 64.
Just can't find it at the moment.

[edit] Found it - Just read carefully if you decide to use it.
