GTX 780 Owners Club

Is this good or bad? (the Samsung memory)

Because it is perceived on other forums, that the Samsung will overclock better compared to Hynix & Elpida ones.

Clocks like a monster on mine.
Memory will hit 7800 before I start getting noticable artifacting.

Samsung > Hynix > Elpida

I have left the power and temps settings at 100/79. Just adjusted the core clock and mem clock and set a custom fan profile. Most of the time I just leave the card at stock as I see no difference in game and prefer it to be nice and quite.

Thanks for that. Cant seem to keep mine stable above 90+ Clock unless I apply overvolt. But Im happy with the 90+ clock and 500+ mem offsets.
 
Went in for a curiosity shot at +650, it blackscreened and needed a reboot after a lap of Heaven.

450 seems to be going strong so far :p
 
+600 should be possible with the hynix ram on the msi card. (been running mine at that for a few weeks) Pushing for +650 blackscreened mine in heaven too. :D

Nice to know. I'll ease it up every few days until I hit the wall that causes issues.
 
My EVGA 780 SC arrived yesterday so I had a play around with it last night.

Until I get it underwater I will keep the voltage at stock.

The memory clocks like a beast. I used Nvidia inspector to check the manufacturer, it's SK Hynix. So far I have only tested this using loops of Heaven 4.0.

1180Mhz GPU core (+115)
1865Mhz Mem (+725)

I'm thinking this is pretty good for stock voltage. I'm going to have another round this evening and see if I can get any more out of it.

GPU-Z is reporting the cards ASIC quality is 81.1%
 
is it worth sorting out an online spread sheet to log which cards are doing what core and memory wise?
 
Presume others see outside of 3d apps, whilst browsing the net for example, the core clock rising to that of the default speed (in my case 954mhz) as opposed to the overclocked speed set in precision x (not boost speed)? Mines set at +70 for 1024mhz in precision x, but it's usually either 324mhz - idle, 954mhz - web browsing (or another lower figure upon change) or gaming - 1176mhz (boost). It never goes to 1024mhz even though it's set for that and states it in GPU-Z. Not that it makes a difference, just seems slightly odd?
