2 ATI HD Radeon 6990's In Crossfire Experienced Experts Only - Page 3

post #21 of 56
The 1100t has a stock clock of 3.3 GHz...
If you overclocked it to 4 GHz or just below you'll definitely see an improvement.

When you overclocked to 4 GHz and saw no improvement is beyond me.

Since you have gotten there successfully please show us some benchmarks comparing stock clocks vs. 4 GHz. That would be helpful.

Why on earth are you running 2 6990's on a 1080p LED TV? It isn't even a true 120HZ as TV's accomplish 120HZ through interlacing.

A 4.0ghz X6 should have no issue running 1080p up to the FPS limit on your TV. In fact, you probably saw no improvement precisely because you're already FPS capped by your TV.

Hardware wise, yes your CPU is a bottleneck, but even if you eliminate that bottleneck you won't see any real world diff thanks to your display limiting you.

With those GPU's you'd need an 3x 1080p eyefinity setup to see a real world bottleneck.

I would recommend getting the 2500K and overclock it to 4.0 GHz that would be able to help you quite alot with he bottleneck.

6990 quad-fire will kill any game at 1080p and you'll hit a bottleneck on any cpu long before your GPUs bottleneck at that resolution. Now 1600P that would be a different story. Like others have said Intel is your immediate solution, BD is your alternate future solution if it has decent single thread performance.

Ok can you explain why i would need to run such high resolutions.

I play everything at 1900x1080

How exactly does this create a bottleneck.
I figured, the lower the resolution, the better the performance and keep in mind i run everything with the highest settings and image quality that the game will allow me to setup.

Let's talk hypothetically here for a second. You successfully overclock your cpu to 10Ghz. The bottleneck that remains is your 1080p 60Hz monitor.
I can max out anything I want with my SLI 570's on my 1080p 60Hz monitor at 60fps which is the highest that my monitor can handle. If you are pushing out higher fps than your screen refreshes (60Hz= 60 refreshes per second) you will experience screen tearing.

Technically he has a 1080i 120hz TV, but ya, still limited to 60fps. Eyefinity with 3 1080p 120hz monitors (not TVs) would make the cards work much harder, remove the monitor bottleneck as much as possible, and help to reduce the bottleneck that exists at the CPU at the same time.

As far as my knowledge stretches with 120hz TVs, they do only accept a 60hz input, but actually interpolate between frames instead of flashing them twice, and the frames are progressively displayed. They certainly don't use interlacing.

120hz mode is always super laggy anyway as far as input is concerned due to all the extra processing being done, so it's a moot point

Well I stand corrected. Either way, one monitor for dual 6990s? That's a huge bottleneck, and if you are getting 60fps (or whatever the max is on the TV), then clocking the cpu higher isn't going to help anything anyway.

EDIT: unless, of course, you just want 300+ fps for bragging rights. But I would still take eyefinity at 60 then a single monitor at 300+ when I cant see it anyway.
