***GTX 780 Ti Owners Thread***

I get my reference 780ti to 1241/2001 on stock volts (stable). Wonder what I could get with some overvolting? Soon as I've got a block on it, I might consider flashing it. But with the cooler vregs it shouldn't hit the power cap anymore

Ditto! I convinced myself that £500 after cash back and game sales was a fair deal. There is a certain satisfaction to finally getting your hands on a full-fat GK110 after first reading about them 18 months ago.

Sold the games for a bit more than I expected, meaning the Ti "only" cost me £490 in the end. :)

Only had chance to slap it in so far. Overclocking will have to wait until the weekend.
 
Tempted to try and WC to see if cooling the VRM's down unleash some more power - cooler VRM's have to be more efficent so we can stay within the power target.
 
VRM temps on GK110 cards are normally pretty good anyway on air, I doubt you'd see much gain. Also these cards run exceptionally cool considering the extra power draw. It's awesome :) At least compared to my old Titans.
 
There's a couple of modded BIOSes about that remove the power limit for all intents and purpose and boost max vcore to 1.25V or something.

I think the limit will be around 1200-1250 boosted.

Unless you can get an unlocked power target bios like the skynet.

How so?

People are already hitting 1300Mhz on the stock air cooler, read this thread, we also managed an easy 1284MHz core 24/7 stable.
 
Think it varies from card to card, there are probably a few that are hitting or close to 1300mhz on stock volts. But mine will barely do 1220 without running into the power limit...

although the memory scaling is amazing at stock volts. Very close to 4000mhz on mine :).

On the whole from what I've read, a lot of the high clocking cards are Gigabyte reference ones.

I agree with Frosty on this tends to be coming from Gigabyte reference cards.

I have to say that unless EVGA precision X is miss reporting my values the power target flag is kicking in 90% of the time long before the voltage cap or overvolt cap.

Heck we can't even get the overvoltage to stick even when using K boost to cap the voltage and remove boosting.

I'd rather keep the boost so that my card can idle at a nice level.

To me the most overclocking for my card came from using a modified fan curve and keeping things cooler.

Memory caps out at +350mhz for me and I just can't push 400 or more without getting lovely flashy green blocks.

Now granted I may well have lost the silicon lottery as it were and that's fair enough but a few others in this thread are hitting a wall around 1200-1250mhz.
 
350 on memory isn't bad, but same as above on the core it's impossible for me to get more than 80mhz offset (circa 1200) stable because the voltage is fluctuating heavily.

The performance is great don't get me wrong, but if the issue is with the power target it's crippling some easy overclocking potential. I don't think we will get anywhere with EVGA on this one though and will have to just jump to a custom BIOS unfortunately.

I think you are right frosty nothing from EVGA. Honestly I feel my card is being artificially held back by this power limit. The card does boost higher bins on stock without extra volts when under the power limit. I think the power limit was set low to give board partners something to move in to with custom pcbs. This will all be proven when a modified power target bios appears.
