GTX 780 Owners Club

There's a post a few pages back from someone using Samsung VRAM saying his OC's pretty badly.

I wouldn't generalise too much based on the manufacturer. There is always going to be slight variations in the manufacturing process.
 
Guys I have one dilemma

I have found both PNY GTX780 XLR8 OC and Zotac GTX780 AMP! at the same price (£5 difference)

Both are clocked the same, and I know the PNY is more recent card, with Samsung VRAM and nice overclocking it seems.
(according to bit-tech review last week).

Any thoughts welcome. Probably going to grab one tonight.

How much ? Is it worth paying the extra for the Gigabyte (I assume the others are cheaper?)
 
They are all at below £400 and at £10 spread.
(was away didn't manage to grab that pny at 370 earlier this week)

Btw the gigabyte is 954 core, 1006 boost. The others are 1006 base, 1059 boost.
 
Ordered the PNY. I do have a better feeling that the rest of them, and the price cannot be beaten. Hell if I sell the games, and probably it will cost me less than £350

..but that's what it is. As you jump into a game, it ramps straight up to 11xx as it has headroom, which is your 1024mhz (+ boost)

If you edited the bios to disable boost your card would top out at 1024 when using 3d.

I meant outside of 3d apps it goes to 954 as opposed to 1024
 
I highly doubt it.

If it did work, you'd be cutting it very close to the limit depending on the quality of the psu, the clock speeds of the 2 cards & the cpu speed / overclock.

Personally I wouldn't risk it.
 
Rule of thumb, an overclocked 780 needs around 400W alone. Plus 200W for an overclocked i7.


Use

or
http://www.thermaltake.outervision.com/

And to give you an indication, run a calc right now, and without optical disk, with an GTX780 OC, 4820K OC, plus a GTX650ti for Physx, is almost 700W.
(included 1 HDD, H100 with 4 custom fans, 4 ddr3 dimms, wifi pci card and 3 USB devices).

Which means, more likely going to need a 800W or 1000W soon. :(

How accurate are the Corsair Link PSU's, because my twin 780s never draw anywhere near what people are saying, according to the power log.

EDIT:

Found something online about accuracy

<100 W = undefined,

100 W to 300 W = +/- 10%

>300 W = +/- 5%.


My 780's and 4670 take between 400 - 500 when BF4'ing

According to Techpowerup review that's within 5%, if it is to be believed.




This was the highest after a map of 32player Zavod Domination
Power in 458.9
Power out 442.2
and never goes above 21 degrees
