Overclocking 9300 - post your results! - Page 3

the nv41 has a better chance of getting a higher core over clock, the some nv42 can still get up (i can get 403) but i think the highest overclock is still on the nv41 with 420-425.

The first is right, thermal shutdown, but do not believe you have a warranty of 1 minute if you overclock your CPU, GPU,..

The NV42 is smaller and then cheaper to produce. And in theory NV42 should be a little bit cooler... but NV41 is more perfected than a brand new NV42, all in theory. And the 6800 Go Ultra is the same only special selected nVidia chips and higher clocked.

Has anbody seen or know which DDR brand with which speed are on our notebooks? I mean the ns from Samsung and Hynix chips, that can be one point in the difference overclocking the DDR.

Right, but doesn't it make more sense for the cooler running 42 to be able to clock higher?? After all, the 42 is the Ultra which I believe is base clocked at 450 MHz. I realize the Ultra is selected from the best yield, but don't see how an older one can clock better.. More perfected would make one think there was a revision or three or four, but I couldn't find anything like that. Oh well though, I have a 42 and it's slightly overclocked and runs perfect and plays games like a dream, so I'm very happy..

just curious if it's possible to unlock the extra pipes in the 6800 go? Seeing the nv42 is based on the same core as the 6800 ultra which has 16 pipes... just wondering if it is theoretically possible, if not now then perhaps in a later revision of riva tuner?

What are you going to unlock? There is nothing locked on the card.

What is the core voltage on the 6800go, my ultra is 1.37.

Also slow memory could hold the core back.

desktop 6800NU cards (nv40) have 12 pixel shaders and 5 vertex shaders enabled. With riva tuner you can unlock 4 extra pixel shaders and 1 vertex shader to take it up to 16 pixel shaders and 6 vertex shaders, putting it on par with a 6800gt & ultra (pipe-wise). The extra pipes increase fill-rate which translates into a decent performance boost (couple hundred extra points in 3dmark03, etc).
Wonder if it's possible with 6800go... heard it can't be done, but maybe with nv42 it's possible seeing as it's based on same core as 6800ultra.

Do not compare desktop 6800 with notebook 6800 go. They are not the same chips and completely different.

The mobile 6800 go (ultra too) has "only" 12 pixel shader.

Anyone with an NV42 take the heatpad off and use Arctic Silver or something similar? Were you able to OC it any higher once you replaced the heatpad? Right now I'm at 370/800 and am hopeing for 380-390 if I replace the heatpad.

I immediately applied AS5, might try to mount it again with even less to see if I can get it any higher. I'm maxing out at 380/790 right now. The memory is getting to hot so I might try keeping it at stock and seeing how far I can push the core.

The reason I was told that the NV41 clocks higher than the NV42 was because it wasn't binned. At the time, there was no 6800Go Ultra, so all NV41s were 6800Go's. If you happened to get a middle of the wafer beauty, you could overclock the hell out of it even though you were sold the same 6800Go as some guy that got a sucky chip. However, with the rise of the NV42s, the chips were binned. The ones that could clock high were labeled sold as 6800GoUltras, the ones that couldn't were downclocked and sold as 6800Gos. That's why the 6800GoUltras run so damn hot, they're the exact same core only clocked much, much higher.

The highest I've ever gotten w/o artifacts is 399/820. I guess I may call myself lucky. I've done no mods what-so-ever to my comp. It's "just" a 9300 + 80.40 drivers + RivaTuner v2.0 RC15.6. This gives me a 3dMark2005 score of 4789. One user on these forums reported a 5k score!!! I wonder how that would be possible!!

Sounds like you just got a really good card. Remember that binning is a non-specific process. If that card couldn't do 450, but lets say could do 400 fine, it was still binned as a 6800Go. Nice grab my man
