Inno3d gtx 460 overclocked @ 917 core = gtx470, How high does your gtx 460 overclock?

[Kallogan]

Yeah i can push the core up to 900 on 1,087 V but i don't know if it's really worth it. Temps go high (i hit 89 degrees with Furmark, only 79 degrees with Kombuster though (???? it's based on Furmark, no ???)) and consumption too. My 460 is in a Sugo sg05b case.

I found the paper i was looking for ;-) They compare GTX 460 memory OCing on both 1GB and 768MB models. Short but very interesting :

89c is not bad for furmark. Most cards go into the mid to high 80's and some into the 90's.

With real in game temps, it will allmost never go that high.

Did you try to lower your voltage just a tad and keep the 900 core?
I would say anything over 850 core is as fast as a 5850, so thats good.

900 mhz overclock is a very good on air (or did you already mount the waterblock?). Did you need 1.1V for that though? I thought you could have gotten away with 1.087 for 900.

I mounted the block already...I'm sure it could have done 900MHz on air though as the Gigabyte cooler is very good. Yeah the Heaven benchmark fails at 900MHz if I go lower than 1.1v. I've done it at 930MHz at 1.175v also but I think I'm gonna keep it at 900MHz for 24/7.

That's odd about DX11. Didn't the RC have everything the retail/OEM version did?

I am not sure but in dxdiag.exe, while my DX Version is 11, under Display it shows DDI Version of 10.1 not 11 :thumbsdown: grrrr...

DDI is the Display Driver Interface.
That would indicate that either your drivers did not install correctly (perhaps because retail drivers don't install on RC properly), or that they are installed properly, but the 11 interface of the RC is not compatible with the final.
So DX11 probably works, but you cannot use the DX11 features.

Scali thanks for the update. I will try reinstalling the drivers and see if anything changes.

Well, I just checked with my Radeon 5770, where DX11 works fine.
It also reports DDI 10.1, so apparently there's no separate DDI 11 version.
So I'm not exactly sure what's wrong with your system, but 10.1 should be okay for a DX11 driver, apparently.

Hmm...when I enable DX11 and Tessellation in Unigine Heaven 2.1, the final benchmark does confirm that the demo ran in DX11. However, Tessellation doesn't work if I enable DX11. Strangely, Tessellation does work if I run the demo on OpenGL mode. Any ideas?

OpenGL 4.0
Res: 1920 x 1080 fullscreen 0AA/4AF
Tessellation mode: Extreme
- Score: 760
- FPS = 30.2
- Min FPS = 17.2
- Max FPS = 72.5

In Dirt 2, I can't set Post-processing past Medium (i.e., I believe High is for DX11 code). So I can definitely confirm that DX11 is not working for me at the moment.

Could someone tell me how far I'll have to overclock a 460 768mb to get 5850 level performance? Is it even possible? Also are the 768mb as good of overclockers like the 1gb's? If I could get 5850 performance out of the 460 768mb I'd be extremely happy. Especially only paying $165 for it.

Looks to be about 800-825MHz depending on the game.
The 768s appear to o/c just a scooch better than the 1GB models, but both o/c extremely well even without voltage tweaks.

I OCed my GB 460 1GB at very conservative 800/1600/2000.
However I'm concerned with temps.

My card idle at very nice 30C. But whenever I stress it, it goes very high. I can hit 77-78C.
1hour of Crysis will get me in the mid 70s too. About 75C.
Even at stock speed, the card is behaving the same minus 1-2 degree.

I red multiple reviews of the card and checked the user feedback on the egg. My understanding is that the card should be at 60C on load.
Do you think I should try and re-sit de Heatsink ? What is the safe limit temp for a fermi GPU ?

 

[Keysplayr]

75C? That's actually a nice cool temp. I wouldn't worry about that at all. Now if you were getting 90C or above, then I'd suspect poor HSF to Core contact or messed up TIM. You're good, don't mess with it.

hey there, now that we got the same card off the same deal what kinda oc did you get out of that card? Mine is thermally limited at 775 for the core (hitting 98-100c) with the fan at 70%. The airflow in my case is quite good and ambient temps are really low as well (they always go crazy with AC at school)

Man, coming from a TTPro cooled 5850, this thing is gosh darn loud even at that. Much quieter and bearable at 60%, but then no oc I guess I wonder if there is a way to fit my spare accelero S1 on this 470? Maybe I will try it on when I dismantle the stock heatsink to reapply the TIM..

If you want to reduce temps, use something like MSI afterburner and a custom fan profile, it will make the card louder though.

My 480s would go up to 90C without a custom fan setting :/ So I used a custom fan profile, temps went down, but they got louder. I have two mini hair-driers blasting out the back of my case.

I tried mine at 751 GPU at stock voltages of 1.0V. Temps get to about 82*C at 77 percent fan speed. I am sure with 1.087V and 100 percent fan speed I can crack 800mhz. I'll test that out in a bit (but I agree that fan speed above 70 is not comfortable). It's still quieter than the 4890 was at 70 percent fan speed! hehe

 

[konakona]

well I am using afterburner of course, that's how I get to peg the fan at 70%. would have been even louder without it.

 

[RussianSensation]

Ya I have my non-overclocked fan profile set to 70 percent max (but it never exceeds 66). Did you overclock the memory at all?

 

[konakona]

IIRC I jacked it up to 1820. Aren't fermis supposed to be mem bandwidth strapped at higher rez? Then again, I am only doing 1600x1200 on it so..

 

[RussianSensation]

The biggest problem with GTX470 is texture fill-rate - less than GTX460! This is a large part of the reason they tank at 2560x1600. 1600x1200 is a good res for a 5850/GTX470. The strange thing is that if one bought a 5870 for $379 in September of 2009, they didn't lose much value until today. On the other hand if you bought the GTX470 for $349 in April, that was a bad purchase! I have a feeling by the time Tessellation and DX11 will be in full swing, we will have moved on to better cards anyway But for the price you and I paid for it, it's a pretty good deal.

 

[Scali]

The problem is with Windows 7 RC, I can't get DX11 to work. I installed the latest DirectX runtime and it's just not working. I don't know if I would need to reinstall Windows or have to get a full version.

I can confirm... it's Windows 7 RC.
I stuck my Radeon 5770 in an old Pentium 4 that I still have around the house. It happened to have Windows 7 Ultimate x64 RC installed on it.
And I get only DX10.1 out of the card, not DX11.
Same card with the same drivers does DX11 without a problem in Windows 7 x64 final.

I also noticed that it only reports OpenGL 3.2, while it should be supporting 4.0.

 

[happy medium]

It says it right on the driver page guys! I thought everyone knew this?

"Windows 7 beta and RC versions are not supported".

"Not supported" doesn't tell you what happens if you install the driver anyway.

Fair enough, but in any event, I'm preety sure thats why it dosen't work.
It didn't work for me either. Now I a have a final release of windows 7 and it's fine.

I was just confirming that it is indeed an RC-related issue.
