Title: Pre-Buy Question for Sapphire Radeon Vapor-X HD 7970 GHz OC 3GB
Post by: emunebtk on June 30, 2013, 08:36:36 AM
Was hoping anyone could help with a little advice on if I should buy this card for $300 used :

Radeon Vapor-X HD 7970 GHz OC 3GB 

http://www.amazon.com/Sapphire-DL-DVI-I-SL-DVI-D-PCI-Express-11197-12-40G/dp/B008PQAE98/ref=sr_1_2?ie=UTF8&qid=1372285900&sr=8-2&keywords=sapphire+radeon+7970 (http://www.amazon.com/Sapphire-DL-DVI-I-SL-DVI-D-PCI-Express-11197-12-40G/dp/B008PQAE98/ref=sr_1_2?ie=UTF8&qid=1372285900&sr=8-2&keywords=sapphire+radeon+7970)

I have read the GHZ editions seems to cause a lot of problems and am curious if anyone has any recent experience with using them for Bitcoin as well as scrypt mining and what type of PSU power you will need for one of these? two?

Also am I going to need to BIOS flash this to get 700+ speeds since it is a GHZ edition? I have a 650w PSU running 1 x GIGABYTE 7970 and am curious if I will need to upgrade to a 850plus to get both working in same pc rig? Thanks for any help or advice in amping up my hashpower :)

I was able to run two ghz 7970 Gigabytes for a couple of weeks with a 660W 80gold power supply.  I didn't have any problems with them out of the box, but I upgraded to a 1250w unit before I started overclocking.

I used to use the model mentioned. The first push was bad as the power module is horrible until the second push. Additionally, You better to find a way to copy yourself for more as GPU only provides basic start.

In Terms of Power Supplies-Try to stay away from discount brand PSU's  

I've Built a 2 card 7970 rig with a 850w PSU
               3 card 7970 rig with a 1000w PSU
               6 card 7970 rig with a 1600w PSU

thats with no overclock?

i wouldnt put my PSU close to full load like that - lowers down the efficiency
