FireWire 800 isn't much faster than USB 2.0, so I wouldn't even consider it. USB 3.0 will be a huge improvement, but the question boils down to whether or not the CF cards themselves are going to take advantage of all that extra bandwidth. Flash chips used for camera cards are not usually that fast, so it depends.

To know whether or not a CF card exceeds the bandwidth of the USB reader, you can just take its rated speed (eg: 150x) and multiply it by 150KB/s. So for a 150x card, the maximum throughput is 22.5MB/s, while USB 2.0 can handle about 35MB/s. I am not sure how fast CF cards are nowadays, though.

As for that overclock... very, very sweet. I get so excited when I see value like that... $100 for a chip that comes close to 4.0GHz. You gotta love it!

Nice results Mischa, too bad the L3 cache didn't unlock. Watch the vcore though, 1.5v already seems like a lot. One suggestion though: maybe you could try lowering the HT Link speed, because it's running very high now.

I can get my 620 stable with L3 cache enabled at 3.65 and with max vcore at 1.38v. Haven't tried higher voltages.

Maybe I should try disabling the L3 again and seeing if it would overclock some higher. But somehow that would be useless because I want to run it with L3 enabled

Thanks, too bad for L3 cache, cause i wanted to use this PC for some 3D rendering too. But OK, i can use it few months more until i chose my next CPU/MoBo combo. I need another "standard" 4-core PC anyway, so this cpu/mobo/mem will get a new home easily.

I know voltage is little above, but i lower bus speed to 270 with default voltage, so now I'm safe

Any way, nice OC for that money, that's for sure!
