Man, this thread wavers hard between Titan is awesome, or Titan is rubbish.

Make up your mind people, you are making me doubting buying one! lol

I don't find too much wrong with 70% ASIC quality. That was a pretty common number before GTX 600s came out. Of course GTX 670s and 680s are like ~90%, so either Kepler GK104 was just damn good in that regard, or we're just getting the reject GK110s.

But even with these "low" ASICs, after flashing a custom bios, pretty much every single Titan out there can do at least 1.1ghz. I'd guess that 75% of them are capable of 1.15ghz, and 40-50% are capable of doing 1.2ghz. And then there a few lucky ones are pushing 1.25ghz.

^ 18.7K graphics score for a single card in the post above, water cooled. How much more awesome can it get? My liquid nitrogen cooled 7970k at 1600/1800 + got 17.8k graphics score

Can someone tell me what's so special about ASIC scores? Sounds to me like it's just an outdated way to measure something. If the Titan can wipe the floor with older cards that score 80 or above, what's the point of caring what your asic score is?

If using one of naennons, where your 3dmark11 barely throttled on first, he has default power to 260W, mine is at 280W because my leaky card was throttling a little at 260W.

+1, no one is complaining about cards, just the immature bios. nvidia is working on fix...in meantime there are plenty of fixes floating around.

Most fun I have had with a single card.

Psychological mainly. A good ASIC versus a bad ASIC can end up as a 10% difference in performance. It's not large, but it's not completely negligible either. But those are the extremes. I'd say that within two standard deviations (whatever that's called) everyone will end up +/- 3% of each other (assuming the rest of the system is exactly the same)

But then of course a bad ASIC card could have memory that clocks to the heavens to make up for it a little bit, and good ASIC card can have pretty crappy memory in the same regard.

Also, is anyone getting significant heat coming from their water cooling rads now? Before I had just the CPU under water, and my radiator barely got warm. Now with Titan dumping an extra 260-300W into the loop, it feels like my computer doubles as an electric heater. It's not bad, just something I found interesting. It's not causing my room to heat up any more than it already did, but it really showed me just how much more effective water cooling is in getting the heat away from the chips and into the ambient. tongue.gif

To bad the fix is really more of a gimp. They need to release new BIOS with a higher power target and voltage.

Anyone volt mod their card yet?

I would assume some of this would carry over.

Looks like whatever bug it is it comes with all the default bios. It made me excited for a second when I saw 13xx on my screen then I was like come on, no way....doh.gif

didnt fix the bug, just my need for max 1.21 volts obviates it.

In all bioses based on naennons, core boost is 1202. Valley assumes that as base speed, because so does bios. If I run precision X...BUT do not have it load with windows and do not hit voltage reset or mess with volts or hit default. The core speed is 1202, I get max volts of 1.21, and valley assumes correct base speed. I then up 33mhz in core, and get 1230 core speed. do same for mem. And valley gets mhz correct, and i get max volts 1.21.

Now run precision X and hit reset, now your bios says 1202, precision X tells the card to run at ~1000-1050 base, and you are at 1000-1050 base. So now move slider 33mhz, and you will be at say 1088 if at 1050 per presision X, but Valley will incorrectly say 1235. (Also your max volts is now only 1.2 via overvoltage). And here is funny part...so now you need to go +200 to get to 1250 core, because precision set card down to 1050...then run a benchmark and crash drivers...well now precision X is no longer holding core down it is back at 1202, and if dont reset precision and core slider still at +200, now your at 1402 boost...now run benchmark without hitting reset and black screen.
