6990 + 6970 Questions - Page 2

post #11 of 19
Thread Starter 
My intention isn't to use these GPUs with waterblocks but it looks like the power supply/motherboard can handle the 450W in OC mode, right?

Have you tried trifire with the 6970 without flipping the switch? Does it work?

The 6990+6970 are bandwitdh beasts. The more the better.
No, trust me, you're right, that 1100T is a bottleneck there, even at 4.2Ghz.

I've had an X6 1055T @ 4.2Ghz with an HD5970, then x2 HD6970, trust me, I had bottleneck due to my CPU, even at 4.2Ghz..

Changed to my i7 2600k, and bottleneck dissapeared...

So yeah, you were right

As mentioned above, he probably won't notice much unless he benchmarks all day long, but it is a fact, and very true fact, that an X6 of AMD is a bottleneck for x2 HD6970 even at 4.2Ghz, so can't imagine a tri-fire...

No. But it will work.

AMD Crossfire/Trifire just lower the clock of the fastest card to the level of the slowest card. Always worked like that.

There was a big ''scarecrow'' campaign about the 6990 by a lot of reviewers. It was really exagerated and blowned out of proportion. You will be fine flipping the switch. Noise, temp and power will be ok. A single 580 running Furmark was more ''risky'' then running the a 6990 on ''the switch'', thats why there was a limiter on the card.

Just ask other real 6990 end-users in the 6990 owners thread. Talk with real people with the card in hands. Not those copy and pasting what they have read somewhere.

Excellent, thanks a lot!

If you don't flip the switch for OC mode and you trifire with a 6970, will it still beat 580 SLI?
post #15 of 19
Yes. 3 chips against 2, more VRAM. Same price.
