301.34 is older than 301.25?
doh I thought I saw .24 on the official website.
Max power limit is 125% ... what does that do?

GPU boost tries to keep the GPU within the power limit, increasing the power limit means boost will be active for longer.
Yeh I noted that in the heaven benchmark thread. Any idea why we can't do more?
So far my max OC on my windforce is +120 gpu clock, +400 mem clock
So the KFA2 is better?
I havnt found the max OCs yet, at stock settings the GPU runs at 1200 Mhz, +100 gives 1316 Mhz and is isnt stable, +85 gives 1300 Mhz and isnt stable, +50 gives 1255 Mhz which is stable.
So my max frequency will probably be around 1270 Mhz too, so much for the extra power power connectors and PCB.
Not tried overclocking the Vram yet.
Actually I'm having very poor luck with the GPU, even +50 isnt bench stable. But my ram is working problem free at +700 / 7400 Mhz

I wonder why is the difference so big 125 v 111
Also does the boost in nvidia cards stop during gaming or its constant when load?

this is backing up what a lot of reviews are seeing, mid 1200's for the EX OC and windforce, even with all the apparent advantages they have

it fluctuates a little but is pretty constant when running a game/benchmark, unless you're in menus etc.
+30 / +650 was almost stable - 1250 / 7300, but the Vram started artifacting a little.
I'm certain that 1250 / 7200 will be stable, testing it now. I was testing clocks in Kombuster first and there wasnt any 'snow' at 7400 Mhz ram, but I needed to reduce it for benchmarks.
The KFA2 EX OC stock speed is already 1200 Mhz, I think thats the highest stock speed out of all of them? And just +30 gives 1250 Mhz.

Well my reference KFA2 seems to be running nicely, it's inaudible on most games, crysis , metro 2033 etc ramps the fan up a bit but still not lot really any louder than my 570 used to be, just a low hum, my P180 case is pretty quiet anyway, all the 120mm fans are set to minimum.
Binary domain maxed out at around 59c, with the core clocked jumping to 1086Mhz but averaging around 915MHz
Metro 2033 maxed out around 77c, core clock seems to stay around 1086Mhz.
Do these cards not have a minimum core clock in games? in lesser intensive games the core clock seems to go right down to 640MHz at times, I find this confusing.

Me also, I don't quite get it how it works out the clock, I've noticed in less intensive game it goes quite low but surely it shouldn't do that because then I'm losing fps?
Is there anyway to keep the clock at a minimum? atm I don't feel my card even has a set clock, only a max clock which is strange.

I think the minimun clock is the base clock and the boost frequency is added to the base clock when added when under load

So you mean even if in the product description it states core boost is xxxx it could infact be more or slightly less?
