Title: How many Mhash/sec can I get out of this Graphics card?
Post by: Dorkslayz on August 26, 2011, 09:44:21 AM
Im looking to get a Sapphire AMD Radeon HD 6870 Vapor-X and I was wondering if any other members have one and how many Mhash/sec I get get out of it.

The specs are,
900 Mhz Core,
1024MB 4200MHz GDDR5 Memory,
1120 Stream Processors.

Im probably going to be using GUIMiner (Phoenix) with it.

Ah, ok. So I can expect around 270Mhash/sec. Should I know anything else about this card before I buy?

If your willing to mess with the core clock and mem clock you could probably push it to at least 300. Depending on how good your card is it might even be able to be pushed up to 330. I would recommend against changing the voltages.

Can you reach 330m/h easily, try Sapphire Trixx and follow the settings of the overclocked comparison page.

Will that auto-overclock it on startup or will it flash the card's bios with the settings?

Will my 500w Modular PSU (http://www.novatech.co.uk/novatech/prods/components/powersupplies/NOV-PSG500.html) be ok for this card too?

Trixx doesn't do any flashing. But it will clock on startup
