8800GTS G92 overclocking: Your speed and gains

I OC'd mine to something around 780/1200 and it was stable, but gave almost no increase in performance (1-2 fps in Crysis, 5-7 other games, ~150 3d06 marks). So I just put it back to EVGA's stock clocks. Wasn't worth it to me.

This is what I am noticing. I have the XFX vanilla card at 650/792. Does this mean the XFX XXX card that cost $50 and run 678/792 really isn't performing much better than the stock clocked cards?

My x1900xtx really showed some performance when OCed and really noticed the differences. With this one I am not. That is why I asked.

I also got the card to run at 800/972 and got through 3dMark05. the results went from 19,110 stock to 19,550 so a little over 400 points for a clock that isnt even stable without mad cooling. I ran the ATI Tools artifact test and got tons of dots. It wasn't stable in any games either.

So 440 points in 3dMark05 takes a 150MHz overclock to achive? I'm not sold on it. I thought there was something wrong with what I was doing but guess not.

Use 3DMark06.

30fps is better than 29fps.....

so there is a benefit.

Yeah, I only improve slightly, too, in 3dMark. I have noticed a difference in games though.

I wonder if I have a PCI-E 2.0 Mobo if the overclock would give me more... I will run stock for a little with the OSD and then overclock later on and see if I notice improvement. I don't care if 3Dmark gains just experience in games.

Dude, don't be mocking the e6400. I blast the pants off all the other dudes I know with there stock e6600, e6800's and what not at the lan party I go to. haha. If I remember correctly ALL stock with my old video card I ran low 11,xxx something on 3dmark05. Then when I Oced the e6400 I was hitting high 12,xxx to 13,000. Then with the video I was hovering just below or right on 14,000. However in games i deffinitly noticed a difference in FPS. I tried it at stock because of the power savings at idle but when I cranked a game on it just didn't do what it could OCed.

I also know my chipset is memory limited, the P35 chipset would do be better than the x975. And I have the Allendale core with 2MB Cache instead of 4MB.

And oddly enough where on most G80s increasing Shader Power was more effective I've found that overclocking the ROP Area of the G92 to be more effective.

Unfortunately, you are right though. The G92 is a beast of a card being kept in a cage by a lack of ROPs...

All I wanted was a G92 based card with a 512Mbit Memory Interface, 1 GB GDDR3, and 24 ROPs. It might be too much to ask...

RV770 anyone?

What are the signs that the GPU is overclocked too much? same for memory? My guess from your comment: to generalize, excessive GPU overclocking pretty much locks up right away, but excessive gfx memory overclocking will display artifacts for multiple seconds or more before it locks up?

With Riva unlink Shaders to Core. Core is the ROP area.

Can you go into more detail on what ROP actually is? I hate not having a full understanding, far beyond what I actually need.

I searched for articles on google and couldnt find anything.

If I at least know what it stands for I can dig deeper.

This link really clears things up. Another way of looking at it for the simple folk is imagine a turbocharged V8 with lots of intake volume with a tiny rear pipe to point where the motor can not get air out of the tail pipe fast enough, G92 has a smaller pipe while the G80 GTX has a bigger pipe making more power with bigger gains.

Who in their right mind Turbocharges a V8 that isn't crazy? Haha, ok besides Deisel's. Or Lengenfelter Corvettes. I get the point though. It does make sense. I just wish nvidia wouldn't have engineered it this way. It doesn't leave much room for OCing and is soft of frustrating. So basically all of those XXX and Extreme OCed GTS's aren't worth beans.

Regardless it is still a wicked card. I was glad I got it and didn't need to get a new power supply to accommodate. That was a real selling point to me. I really am learning alot from this thread from everyone and the directions you are pointing me. I like to know everything about my PC and it's abilities... I feel bad for my buddy he bought 3 GTS's for 3-way SLI and just learned he needs Vista to do this. He was grumbling saying he should have just gotten 2 GTS's

I said except for deisels.... YES you have to have vista for Tri-SLI and unless you run it at super high resolution it actually performs worse. It's so powerful that it actually runs bad unless you use the power. That and you need a 1200W PSU

I saw a benchmark somewhere that the ATI cards, the 38XX series see an increase when using PCI-E 2.0 so I wonder if Nvida has a similar effect

If I remember correctly the 2900pro acutally used the same chip as a higher card and would OC well. The 3850 is a great card for the money. I'm not a fan of the single slot coolers so be leary of cooling. I didnt go with ATI even thought i have a crossfire board because it would only be (2) 8X PCI-e slots when in CF. I'll probably go for an SLI mobo next time.

wow, your all having better luck with the 8800gts 512 than I am. I got a pathetic 8k in 3dmark06 with a 8800gts 512, q6700, 8gigs of pc6400 ram, evga 780i mobo, 825watt pc power&cooling psu. I should be able to get 13k with nothing overclocked, dunno what the problem is

That does seem low. Mind if I ask a few questions?

Have you done any troubleshooting?
What version of Windows?
Which driver version?
Did you do a clean install after removing the previous card?
Can you confirm memory clocks, FSB and CPU speed? Maybe something is set wrong in BIOS?

Kinda goin OT by askin, but Id be happy to help.

I'm on this post as single card champ with Vista and my evga 8800GTS 512@ 820/2008/2206 and 4Ghz for my Q6600 I watched my score jump up when I touched my memory speed, it seems to be the limiter. I just got a new cooler on it today. I just bought a 780i too . I go for the extreme though. I stuck it out side in the cold for that score lol . I'm half tempted to stick it back outside again and jack it up.

i think you must not to OC your SP(StreamProcessor), it's the most important factor of the performance. and GPU's OC not make so great improve. The SP'S frequency about 2.x times(GPU's frequency about )
if your make your SP's frequency increase,the performance will make it's linear increase. and there were some tool could unlock the SP ,so......
