I would like to overclock the "Asus HD7850-DC2-2GD5 Radeon HD7850 Direct CU II 2GB GDDR5 pci-e3.0" arriving tomorrow hopefully.
I have done a lot of research but most of the documentation is old and I've been finding so many conflicting views and ideas that I'm still just lost - only in a different way of being lost!
Can someone give me a run down of a simple / safe way to OC my card without increasing the voltage?
This is what I intend to do plus my questions in certain areas, and please correct me:
1. Burn in the card - what software should I use; MSI kombustor? If so, what settings? 2. OC in 25mhz increments for core speed and memory speed, as far as I can without increasing the voltage or until artifacts appear - in which case I'd set back 50mhz and leave it - Still not sure what software I should use for (a) stress testing and (b) overclocking, but is MSI afterburner adequate or should I use some ATI software, if so, which? 2.1 What fan speed should I set it to? 2.2 What other settings do I need to change?
I will share my system specs where relevant:
i7 sandy-bridge 2600k CPU @ 3.4ghz (no OC) Gigabyte Z68MA-D2H-B3 mobo 8GB (2x4GB) Corsair Vengeance ram @ 1600mhz (no OC) Corsair 600T Mid Tower
3. Should I increase voltage and go for a higher OC on this card? It seems more than capable but I'm worried because I can not afford to replace it.
I appreciate any help, please keep in mind I did research this but just got confused along the way, would like something set in stone particularly for my specific graphics card.

More aboutasus hd7850 software
Use the asus gpu tweak and enable the enhance overclocking or whatever. they give you a safe voltage range, but the stock voltage is around 1.15 or so and theyre good to 1.3v so idk what youre worried about. I bought the same card from amazon and Im able to hit 1250/1600(think its 6200 in the gpu tweak) at 1.2v but I keep it at 1200/1500 1.18 just to be safe
Thanks for that - I suppose I can up the voltage a little then.
What software should I use for burn in + stress test? And what about the fan speed?
