Zotac 780 Ti OC - overclocking to AMP spec?
I bought this : http://www.scan.co.uk/products/3gb-zotac-gtx-780-ti-ove...

ZOTAC GTX780Ti OC

Now there's an AMP version which i believe is the same PCB / HSF ... can i oc this card to its AMP version ? - are the cards identical ? - was thinking maybe its a bios update?

if so what s/w shall i use for the 780 TI?

i used MSI afterburner for my 3 x 280x's which i've just sold to buy this.

That jump in GPU clock speed is probably due to Nvidia's GPU Boost, which occurs at the hardware level. Now, your card is rated to boost to 1006Mhz at a minimum due to the gpu chip bin those cards were selected from. The AMP version is probably higher clocked and stable gpu chip bins that will boost to a minimum of 1071Mhz. Now depending on your chip lottery it may boost well higher due to Nvidia Boost....but at a minimum it's guaranteed 1006 Mhz.

Just got my Zotac 780ti OC today, and I have it at 1185Mhz stable in BF4 Ultra 1920x1080.

What is confusing me patrick is the core is supposed to be 941mhz and boost to 1006 , but it actually boosts to 1071 (+65 boost on STOC)



during benchmark:



This points to the OC edition is identical to the AMP version 1006 MHz (base) 1072 MHz (boost) - with the only difference being 200mhz on the memory on the OC version than the AMP version?
