post #1631 of 28144
Sorry to be posting so much, but I figured since we are all learning about this card and how it works, it is better to have more information out and about.

For the last 30 minutes or so I have been running with the following settings on my Titan:

Power Target : 106
Temp Target: 85c (Not Linked)
Core Offset: +150 (standard non-sc version of Titan)
Memory : Standard
Fan Profile: 1:1, when it is 60c, fan is at 60% etc.
Voltage is at standard

So far I have had NO downthrottling and smooth sailing. It has stayed at rock solid 1124mhz, 1.162v, GPU Power is showing between 87-92%, GPU Usage at 97-99%, Temp has not exceeded 70c in the last 30 min or so of Unigine Runs (still running as of now).

Interesting enough, earlier in the day when I started testing, I did get throttling on my card, at the same offset and other settings with the exception of the fan curve. When I did get throttling, the card did hit around 80c at some poing, but I also had the fan running around a +5 over temp. So when the card was hitting 70c, I had the fan at 75% etc. I am really starting to see that the throttling is between the temp and the fan speed, but I know not everyone is experiencing throttling. I can create the throttling by allowing a little bit of heat, but a much more agressive fan profile which does not make a lot of sense to me.

Hope this is useful to someone. Will report back with more results.

Edit: Just crashed at +150 with same setting and no voltage increase. Going to test +150 and a little voltage to see if crashes again.

It seems a brave soul has hex edited the titan bios and seems to have good news.

Can you clock the card higher than before?

^ Awesome good to know, and glad you guys are sorting this out while I wait for the Hydrocoppers to release.

A guy on XS.

Earlier today from him: "So I changed the 04 0B 28 at 8DCF-8DD1 to 04 32 38
which corresponds to changing 265000 to 275000. I also fixed the checksum at 0000F9FF. In theory I should be ready to flash, right? I figured I'd start with a minimal 10watt boost. I'm kind of chicken with the $1000 board though."

Then just awhile ago the quote about it working, I wasn't sure about the rules for linking to other forums so I just quoted.

The official rule is that you should link to OCN if the info is available on OCN. Since it isn't in this case...

Ok Thanks, a few people around here have seemed to be angered by my silly jokes so I'm trying not to ruffle anymore feathers. biggrin.gif

Ok...some more findings...

Changed Voltage to +25 on the voltage meter. Seems like you can go +13, +25, +37. At default with no voltage I was getting a reported 1.162v on the monitoring software. At +37 voltage I was getting 1.187 voltage, so decided to go to +25 and it is also showing voltage running at +1.187, which is the same if you have it set to +37. What is odd is that I just noticed my clock speed is at 1150mhz, but I did not change my offset, it still is at +150 like before. GPU Power has gone up a bit, averging 95% now, which I assume why it is boosting to 1150mhz vs. the 1124mhz without any voltage.

Next test is to see what the voltage reads at when using only +13, but want to have Unigine run to see if it crashes at +25 voltage and +150 on the core.

Will keep you all postedted. Oh temps have hit a high of 71, but still no down-throttling happening as of yet. smile.gif
