Any success with O/C non-VIVO X800 pro?

[monkelyoy]

As a non-VIVO owner, I wonder how much success people have had trying to O/C? I was able to O/C to 500/500 (core/memory) but only appreciated a minimal performance boost and experienced a single CTD while playing HL2. I am currently running at the default clock. I guess that enabling the extra 4 pipes makes all the difference?

As an aside, I am playing HF2 at 1600X1200, 4X AA with only a rare slow down. With FRAPS, I'm running between 30-110 FPS, mostly 50-70. I find it interesting that, in the SLI article, they don't consider the 6800 Ultra as "playable" at 16X12 with AA, since it "only" averaged 64 fps on their most intensive demo. Isn't expecting too much that a game is only "playable" when the average FPS is over 80? Personally, I think that HL2 looks WAY too good at 16X12 not to try it. Any thoughts?

I play with Vsync on, so I'm not concerned about getting 100 fps. I play 1280x1024 4x FSAA 4x AF. I have not tried overclocking, I'm sure it wouldn't do much so why bother.

The x800pro I used to have (sold to another member of the forums) could clock to 575/575 on stock cooling. W/ an ATI Silencer, it never went above 48C under load in my case. It was non-VIVO, BBA.

kyparrish,

What flavor of X800 pro was that? I have the ATI manufactured card. Did you do any benchmarking before and after the O/C?

built by ATI x800pro...

Off the top of my head, at stock speeds, it barely broke 10k in 3dmark03, with the OC, it was ~ 11,500 I think? There was a DEFINITE performance increase at the high clock speeds.

Thanks, you deleted that in your FS/FT post, saves me the trouble of having to 'find' the points again.

I was up to 550/500

Going from stock to 550/500 for me basically meant for me that Battlefield: Vietnam is now barely playable at high-high-high 1600x1200 0xAA / 8xAF, where before I would've had to bump down to 1280x960 or medium graphics, though I still have to jump down if I want things to be perfectly smooth when zooming. BTW, even at 1024x768 zooming with graphics at 'highest' was not smooth in either case, I don't know how they expect anybody to play with graphics at highest. With FPS barely in the 20s with an x800pro and 1024x768, I can't imagine what kind of hardware it would take to push 1600x1200 at decent framrates.

With FRAPS, I was seeing about 10-15% improvement on average at 550/500 vs. the stock speeds.

Of course unlocking pipes will make things a much larger improvement. It essentially overclocks the core 33% over stock even at default speed. You're never going to get a Pro core up to the 630 MHz you'd need to equal unlocking 4 extra pipes.

To me "playable" means >40FPS in ANY case. This is in terms of online FPS games.

I have done some very extensive FRAPS testing with BFV. Typically I cap the FPS at 80 FPS after I get the data (because who the hell cares about FPS greater than this, my refresh rate is usually 75-85 Hz, not like I'm going to be able to see better than this anyway).

I've had situations where the average is 70+ (keeping in mind that 80 FPS is the max) and zooming with a rifle is still in the LOW 20s. I have other combinations of settings where the average is 70+ and the minimum is in the 50s or even 60s. AVG FPS is a virtually useless number. Without a way of determining min FPS, I don't think you can use someone else's numbers to determine how playable a game is for YOU at a particular resolution, settings, etc...

Other games, like 1 player FPS, RPG, RTS, etc... have a LOT more leeway. I can tolerate significantly lower FPS in a game like Doom3 or Splinter Cell, where the pace of the action is more controllable by me.

I will try to push up the core and memory again to see what's up. I found out that my CTD in HL2 was not due to overclocking my video card, but likely the result of my sound card. This "stuttering" problem has been discussed in the Overclockers forum.
