It has nothing to to with 4GHZ the CPU would only bottle neck if the cards were pushing 1GHZ+ core.

Like I said at 1 GB VRAM they sclale fairly ok.
This is a software issue with 99% probability.

Just make sure you have 11.4 installed.
Make Windows is accepting both cards then make sure the driver is too.
If that does not help check the power connectors and if that does not help either give them to a friend with a different rig to test them.

And if lastly that does not help either return them immediately.

You're right, the CPU isn't bottlenecking the cards the CPU/NB is. 1gb of Vram has nothing to do with how well they scale especially considering monitor resolution is less than 1920x1200 so I don't know what you're talking about there.

Don´t be to quick there

Resolution is one factor that can overwhelm the VRAM you are forgetting that there is also AA, AF ,Vsync and several other graphical settings and enhancement options that exhaust the VRAM and even if the res is only 1680x 1024 if all those settings are stressed 1024 MB VRAM can be the cause of a scaling problem.

But in his case I am pretty sure the issue is software related.
Also NB has nothing to to with the problem that is ridiclulous with stock cards.

OP just do the things I listed above and you should be fine if not you should look into RMA.

No, it's not the NB, it's the CPU/NB or the IMC. Where do you deduct that this is ridiculous? This is something I have tested with various AMD systems spanning various ATi cards in CrossFire. The main bottleneck, escpecially when using two or more GPU's is the IMC. 1024mb ov Vram is perfectly capable of running AA, AF, and Vsync maxed out on most games. I'm not being quick, I'm giving truthful testimony based of of experience with this exact hardware. So your suggestion is to have to OP do something that won't really work and then to return perfectly good hardware. You seem to be basing your assumptions off of an Intel system so don't be so quick.

I am not sure about NB or controller. But I do not think he should get that kind of frames with 3.33 Ghz or 1 GB VRAM. He can definitely do better with an overclock. I think he got something else going on. But being so rude, I guess he deserves what he is getting.
When I was benching my cards with heaven, I was getting about 43 with one card. About 85 with cfx with stock GPU and CPU. And jumped to 90 with CPU at 3.6 and GPU stock. And then to about 100 with GPU overclocked. From 3.6 to 3.8 CPU, jump in frame rate was maybe 1. Some runs they were the same.

Is this with an AMD system or Intel system? Intel systems won't have the issue that an AMD system will as Intel doesn't have a horrendeous memory controller with their current CPU's.

This is on my sig rig. Well, guess I am still an AMD CPU noob.

Apparently you dont know a thing about AMD systems. His CF is getting horribly bottlenecked because of the 1055T, and the horrible IMC it has. IMC = NB on AMD systems.

And 1024MB VRAM is perfectly fine, the scaling problem is because of his CPU.

Sorry but obviously you are quite not there yet
CPU/NB or NB regardless , because it has nothing to do with it.
There are about 10 people every 2 days posting this problem and 80% of the time it is software related.
Not to make absolute assumptions here but it is most likely this case also is software or assembly related.

I told the OP to do this :

beforeRMA´ing the cards.
As these are the problems happening almost 80% of situations of the kind.

Priest.-FTX-.: I'm just saying, your scaling is pretty bad, you barely get 10 frames from the second card...
name removed: **** you, I'm fine. My CPU doesn't need to go any higher, it is fast. Take your 4GHZ and shove it.

*copied directly from steam*

so... show's over, folks. Thanks for the advice.
Looks like you touched a nerve lol.
