canyon test ist nothing

my card is 1202 stable in all situations and this canyon test i can run 100 times at 1241 coreclock - no problems

Since Titan is very powerful card, its quite posible that it downclocks.
Of course you cant posibly test the OC stability when it downclocks.
Did you try increasing resolution and AA so it doesnt downlclock ?
Maybe even custom res is required, but properly tested, belive me Canyon is best way to test OC

I was going to say that canyon is not that great of a stability test based on gpu usage... but the canyon test did just nail my 1254 core +200 mem at 10 seconds into canyon test, both times I ran it. I can bench heaven and tomb raider all day with 1254 core +200 mem, and I get through fire strike about 3 out of 4 times at 1254 core/+200 mem. Dont know if canyon test is better than looping fire strike, but seems pretty efficient at catching my unstable 1254 core/+200 mem.

I am not even getting 99% through entire Canyon on my gtx 660 yet it doesnt metter, it still crashes on unstable OC.
It really is great way to test, I would suggest people with Titans atleast jack up AA and resolution, so your card doesnt downclocks.

As for green arttifacts, I am only getting it when I push my memory to far.. ( also only on Canyon )

Never ran mine on air, have EK wb with backplate. my gpu temps typically 35c at load.

Naenons (or edits with it) is the only bios that has some setting that you cant see/change in kepler bios tweaker, that has the potential to completely prevent throttling. My card is leakier more power hungry than his, so I just had to increase kepler visible power limits a little further. Other changes I made were to satisfy my OCD.

The bios isnt going to change any stability or instability you have....just increase power limits before throttling, which should eliminate it in any normal power draw benchmarking.

sk3tch has made a page with all bioses, and info you need: http://1pcent.com/?p=277

best thing to do is go there, download kepler editor, and read some of the bioses, wont take long.

naenons is 121gb115. (changes I made are circled in red.)

Only change I made that mattered for me, I had to increase the default power limits from his 260,000 to my 285,000 to eliminate rest of my throttling..

Other changes I made for my OCD.
1) increase boost clock to 928, I bought SC series, with higher boost clock so I increased it back to my stock value. Does it matter....no. all that matters is boost limit, but it bothered my OCD
2) used slider to decrease boost limit back to 1202....does that matter, again no, already limited to 1202 by boost table on another tab...but again, the OCD
3) increased max mw to 310,000. If I understood naenons post correctly, cant go past 300,000, so that was a meaningless change, just my OCD isnt bad enough to go change that back.

btw...if you do use his bios, when you flash, nvflash will whine about image difference, and your card will beep at you, then you will have to reload your drivers after you turn off computer, and then turn it back on.

Other than that your on your own at your own risk biggrin.gif

What's the highest voltage BIOS at the moment? What's the highest volt/power one that doesn't usually throttle?

A bit of a late reply but yes, you can get that. Unfortunately I just have way too much studies to do at the moment but I promise that I'll try and do it next week. :/

With naennons bios, it does not downclock. btw, b/c of thottling issue on titans not using a version of his bios, my guess is everyone is using precision x or an equivalent, and soon as bench test is over immediately looks to see if core stayed rock stable or not. It is like part of benching a titan now...bench isnt over until viewing core speed log:p

My Titan goes through Canyon like a hot knife through butter overclocked at any res.. but at 1024x768 and 1280x1024 it shows green artifacts...even when severely downclocked from stock. Any other res and there are no artifacts at all.

Very strange.

I always just ran the stock benchmark... after trying other resolutions, the artifacts are gone completely. 2560x1600 doesn't even show any artifacts.

It's weird. As I said, I severely downclocked the card just to be sure and there are still artifacts(the same amount) at those resolutions.

Any insight?

I'm gonna do a bit more testing.

Might be worth noting that I'm on the latest 314.21 betas.

Ah, i see - i have check it also with 3DMark11 and it is the same - when i set +350 and start Test 1 with 1920x1200 (16:10) resolution in fullscreen mode it doesn't show green artifacts, when i set the resoluton to 1600x900 (16:9) also in fullscreen it shows green artifacts! Very strange!

Maybe its your memory. I can oc the memory in heaven like to 7200 but only 6400 (+200) in any 3dmark.
post #4790 of 28139
I flashed to a 1.2v bios to help overclocking but was wondering how I find out the original brand the bios was from. My cards are Gigabyte and I would feel happier knowing that the 1.2v bios I was running originated from a gigabyte titan. That way i'm covered under warranty right?
Where as if I have a EVGA bios installed and my card stopped working I would have no warranty?
