8800GTS 640MB Fan Stopping BFBC2 Crashes Artifacts

post #1 of 4
Thread Starter 
Hey guys,

I need a little help diagnosing a problem with my computer because I can't tell if my video card is checking out or if just the fan on the card is dieing or if it's something else in the system such as RAM.

The problem is this:

I have been playing Battlefield Bad Company 2 a lot lately and the game pushes my system to its very limit (the processor mainly). While most of the time I get a playable frame rate of 30fps on average I do experience lag spikes that cause my FPS to drop to the single digits (seemingly at random).

The game crashes on me in different ways and does different things depending on how I configure my hardware... (Which set of 2x1GB of RAM is in use).

The worst crashes I have had have been these:

On one occasion the GPU's fan on the primary GPU (the older of the two) stopped and I did not notice until the game slowed down dramatically in FPS and then crashed. Upon getting back to the desktop I quickly checked MSI afterburner (which I use to monitor FPS and adjust fan speeds) the card was over 100 degrees Celsius!

At the time I thought it might be because I had JUST updated my GFX drivers, but didn't bother to use driver sweeper that time - instead opting to allow Nvidia to do a normal uninstall and "clean" install routine. After performing a clean install of the driver using driver sweeper however my problems persisted.

One of the worst crashes I had with the game happened when I tried to isolate a single 1GB stick of the RAM I had bought from eBay for testing. I then played BFBC2 for about 20 minutes or so and then yellow triangular artifacts / blotches started to appear on the screen, getting quickly worse and worse until the game crashed. My system blue screened and refused to post for about 2-3 attempts and then rebooted into Windows fine. - After this happened I thought surely that stick of RAM was the culprit so I ran Memtest 86+ 4.20 on it for 25 hours and got no errors... Even though Memtest didn't find anything I decided to try my original (5 year old) 2x1GB kit for a while and it worked for the most part pretty well - no more artifacting.

So tonight I decided to see if I could play test the eBay RAM again and see if anything unusual happens. I put in both 1GB sticks from eBay this time (none of my.. "Good" 5 year old RAM) - So after a long session of about 2 hours of play on BFBC2 the fan stopped running on the primary GPU again - as evidenced by the game slowing to a constant 15FPS. When I got out to the desktop MSI afterburner showed the Fan speed at 0% and the temp at over 100 C again on the primary GPU.

Could bad RAM or a flakey CPU cause the GPU fan to stop? (my theory is that MSI afterburner is controlling the fan speed and is loaded into memory so if the memory got corrupted then the fan might stop).

I want to track down what's causing all these crashes with the game and causing my computer to not boot sometimes before my upgrade parts get here... I ordered a new Phenom II 830 CPU and a Geforce 560ti and will be upgrading to Windows 7 64-Bit as well.. I also want to be able to run all 4 GB of RAM with Windows 7 but I am still not sure if the RAM could be the cause of my problems...

FYI My system specs should be there in detail in my SIG and here's some other info on the age of my system:

My computer is now 5 years old as of January 1012 but not ALL the components are that old - for example:

My Corsair 750TX PSU was bought in the last year after a Thermaltake Toughpower 700W died on me.
2x1GB Corsair XMS2 LED RAM was purchased from eBay this past summer and is highly suspect as the faulty part.
My second 8800GTS 640MB was purchased from eBay at the same time as the RAM. According to the seller it didn't have much use and the fan was appropriately clean and totally devoid of dust.
2 WD Black 640GB in Raid 0 were purchased in the last 1-2 years.

The parts in the PC that are actually 5 years old however are:

The M2N SLI Deluxe motherboard
The AMD Athlon X2 5200+ Processor (OCed to 3.0Ghz from 2.6 stock this summer) Highly suspect this could be part of the problem because of its age but has shown no signs that it is not working properly. I have even managed to run Prime 95 on blend for over an hour and 10 mins with the overclock applied.
2x1GB Corsair RAM that was purchased when the PC was built (Separate from the kit bought on eBay much later)

Okay I've been doing some more testing and as one member suggested in a PM I should try to turn off any overclock on my system and try to play again.

So after resetting my system to defaults - much to my surprise I was able to play BFBC2 for 2 games of squad deathmatch with only 1GB of the ebay RAM installed with no issues. Now of course 2 games is hardly enough to make any judgements, but upon exiting the game, I opened MSI afterburner which reported a max temperature of 53C reached on BOTH 8800GTS cards. I am running the same fan profile I always do which runs the fan speed at 80% when the cards reach 50C and 100% when they hit 55C.

The thing that was odd is that while my system was overclocked both cards would reach a max temp of about 65-67C !

Why would there be such a large difference of heat in my GPUs when only the CPU was overclocked? Please note that my OC kept the motherboard HT at 1000MHz (stock) and RAM slightly underclocked to DDR2 750 instead of DDR2 800. I OCed by lowering the CPU multi to x12 and raising the system clock to 250 and setting 1.45v for CPU core in BIOS. (CPU-Z always read the CPU core voltage as about 1.35V however).

Assuming that my system regains all stability after turning off my CPU overclock would this indicate the CPU is worn - or could it be the motherboard? Does the motherboard itself NEED any special tweaking - like Northbridge / chipset voltage etc. ? I was under the impression that chipset voltage only needed to be played with if you encountered instability during motherboard OC isolation testing. When I tested my mobo it would go to about 280 system clock (FSB) and a HT speed of around 1300 or so - neither of which did my 24/7 OC come anywhere NEAR - so I assumed no tweak was needed to any other voltages on the mobo.

It sort of seems like some power / distribution issues are going on here. My system seemed to have the most issues with having all 4GB of ram installed in it and running the OC with my processor at 3.0GHz.

My PSU however is on the new side (under a year old) and it's a corsair 750W TX non-modular PSU. Unless it's defective I don't see how this could be the problem but I guess anything is possible... According to extreme PSU calculator my system should use just under 500W at max load and with my own testing using a "Kill-a-Watt" meter from Think Geek the system does in fact hover in the 475W range while gaming AND overclocked. What gives?

It could be a compatibility issue with Afterburner to your drivers. Have you tried turning off your custom fan profile and just letting the cards run their factory fan profile?

I had always suspected Afterburner might have some role in this. And to answer your question - no I have not tried uninstalling or disabling it. I sort of grew fond of having a constant FPS meter from the on screen display in all my games (especially BFBC2 where performance is critical).

I run version 2.1.0 of MSI afterburner and Nvidia driver 285.58 which is the latest release with support for the 8800GTS.

If I come across any other problems with the fan stopping on my primary card I might try uninstalling MSI afterburner or giving EVGA's precision a try. Have you heard of anyone having an issue using afterburner just for the fan profile and On-Screen-Display using Windows XP and or GFX cards similar to mine?

Thanks for the suggestion.
