Just bought this off my friend (he upgraded to a 7800), anyways i've read you can easily unlock this card to 16 pipes plus an extra shader and i'm wondering if the stock cooling is fine or if i would need a aftermarket cooler to run it with the pipes unlocked, i don't plan on o/cing i just want the performance boost of the extra pipelines.

Stock cooling should be fine even with OCing if you don't turn it on too high.

Okay thanks but just to be safe, if it did get to hot i would notice before any real damage occured to it right?

Okay, i have a new problem. I just put in the card everything seems to be okay, however in 3dmark05 i rarely get anything above 12 fps. I checked the options and everything seems to be set right.

Well, you're running 3dmark05. Nothing sounds out of the ordinary there. It's very tough on graphics cards.

edit: actually, check the normal stuff to make sure you're not running with AA or anything cranked up. 12 does seem a bit too low.

This is stock, right? 12FPS should be fine... however if you still get that overclocked and unlocked, then it there's something wrong.

You'll know before it starts melting... when it gets too hot you'll see artifacts in game... if there's like patches turning weird colors, etc, then that means that your card is overclocked too far, and then you should tune it down.

if it overheats, you will notice artifacts (little glitches) on the screen during gaming. you will notice if its overheating. just keep the hsf free of dust, dont let your room temps go up to high.

Alright I have another problem hopefully you guys can help me out. Heres my system amd 3400+, 1gig pc3200, xfx 6800, dfi mobo. I'm running my card at stock right now non-unlocked. When playing cs source at only 800x600 i'll get random drops to 40 fps then the rest of the time i'll be well over 100. I don't really know what the problem is here but it's really annoying to get such a sudden slow down this frequently.

I'm running the lastest 85 drivers, is there anything i should change in bios or my card settings, or should i try a different driver version?

Okay, i'm running unlocked at 16,6, overclocked core and mem 30mhz each to start, 3dmark03 and quake 4 run beautifully but source still hates me i dunno what the problem is but im experiancing like 50 and 40 fps drops during parts of the game.

Hmm i get this stuttering problem in other games too, its just a random slowdown to 20 or 30 fps almost a freeze, then it kicks back to a playable framerate, is there anything in bios or my card options i should change, or should i try new drivers etc?

What's your 3dmark05 score?

I wouldn't reccomend using the new drivers for a 6800...

77.77 / 78.01 / 78.05 are typically best for 6X00 series..., and make sure you don't have all the eye candy cranked to MAX when you're playing online games...such as AA AF and vsync (if you're using 100 hz already).

Okay just installed the 77 drivers, tested source on 800x600 with medium settings, i get drops to 30fps when say a grenade goes off. It wasn't even this bad when i was using my old 4600 card.

Ok now try the 78.05, it's updated for HL2 / Lost Coast...

What do you get in 3DMark05, as long as it's around or over 3.5k or so, it shouldn't be a clock problem, make SURE you have AA / AF / vsync off, just because it says it's off in HL2, doesn't always mean it's off (for me at least), you have to turn it off in the nvidia drivers settings.

I have not even ran the whole 3dmark05 test, i was getting like 15-25 fps on the tests. Yea i disabled the aa af in the card settings. I was just playing fear on fairly high settings and it ran better than source does which seems odd. Let me run 3dmark05 and tell you the score.

That sounds about right...depending on your CPU.

Make sure you have AA and AF off when playing source unless you show no fps lag. Turn your driver settings for AA / AF / vertical sync to application controlled.

all aa and af and vsync is off. both on my settings and in game. does my aperture size in bios matter, its at 128? or fastwrites?

I'd keep fastwrites on unless you want to overclock a bit more than it would with it on, just to be safe.

Try bumping aperture to 256mb.
AGP fastwrites on, and AGP bus at 8x.

Pretty sure it's the ammount of memory allocated specifically for the GPU, just try it.

Set agp aperture to 256, that might help.

I replaced the stock cooler on mine because it was too loud, zalman vf700cu lowered temps by about 10c.

That stuttering you're getting may be caused by your Virtual Memory settings being too low. Try increasing that.

There's a heap file command line that you can use in HL2, might work for CS:S.

Taken from http://www.tweakguides.com/HL2_7.html. There's some other good tweaks there too.

"Similar to the way you can add command variables to the Steam Launch Options, you can also add them to the Half Life 2 startup by editing the desktop icon used to launch the game. If you don't have a desktop icon for Half Life 2, go to Steam>Play Games and right-click on Half Life 2 under 'My Games', then select 'Create desktop shortcut'. Right-click on the desktop icon for Half Life 2 and select Properties. Under the properties, you can enter command variables in the Target box. For example:

"C:\Program Files\Valve\Steam\Steam.exe" -applaunch 220 -heapsize 512000 +map_background none

The above command line will launch Half Life 2 (-applaunch 220) with a memory allocation of around 500MB (-heapsize 512000), and Half Life 2 will start without a 3D background on the main menu (+map_background none). You can add as many variables as will fit in the Target box, simply make sure you put a single space between each command.

Note that unlike entering the commands in the Steam Launch Options box, if you enter them in the desktop icon's Target box they will not apply when you run Half Life 2 from Steam, whereas the Steam Launch Option variables will apply to Half Life 2 even when you launch it from a desktop icon."

Set the pagefile to twice your physical memory...if you've got 1024mb then set pagefile to 2048 min 2048 max. That's a gaming setup though, you can be "leaking" pagefile mem if you're not using it.

Unless D: is a separate physical drive, just use the pagefile on C:. You want your pagefile to be as close to the "beginning" of a physical drive as possible, so if you put it on a separate partition it won't access as quickly.
