HD5770 vaporx crossfire usage

[zookeeper525]

I'm having a lot of problem's with usage for my two cards. I'm lucky to get 60% usage on both cards at a time. On crysis 2 i only get around 50-60% usage on both and on the bf3 beta i only see around 50% usage as well. The most i've seen is on bc2 where i get around 70% usage but it dips all over the place from like 40-90% but 90 is very rare doesnt stay on it for long and it usally dips back down. Am i using the wrong drivers or something? Does the vapor x 5770's need different driver then normal ones? Right now i'm using drivers for the 5700 series and it's up to date with amds site.

So what are some things i can do to boost the usage of both these cards? are there some settings in ccc that i'm missing or something?

@malmental I'll try that later on when the new rage drivers come out.

I know this sounds odd but take a look at your link bridges. Each end should be labeled something like "J1A" and "J2A." Make sure that "J1A" is connected to the top card and "J2A" is connected to the bottom card. Cleared up my crossfire issues. YMMV.

I don't see anything like j2a or j2a on my bridges.

Will be on the under side, near the connectors them selves. Might be labeled differently but should denote 1 and 2. It may not make any difference these days, but it seems to have solved my issues. Once I started looking into it I found that it often mattered on older crossfire systems.

I don't see any thing like one or two on the top or under the bridge, maybe it doesn't matter anymore like you said?
