Got a BSOD with those settings but wasn't quick enough to get the error code, then it wouldn't boot so I reset setting >.<

Yeah and the 50D has a pretty good AF system but maybe I am just wanting to do the impossible here Maybe it's just me but MF is very hard when shooting tiny bugs 3 ft away with a non-macro lens
Another thing I want to complain about the 50D is it produces huge amount of noise even at ISO 200 if the background is underexposed. I don't think I have ever used that camera at ISO 1600 not to mention the highest ones because I know the images would be totally useless.



Well I have been shooting with a 50D and EF 135mm f2L most of the time lately.
I am not really sure what lines of contrast means
but I can give you an example here.
I had a major problem focusing on the tiny body of this spider. This one was actually the only shot that turned out to be reasonably sharp and when I tried to shoot it from a slightly different angle the AF just haunts.


Speaking of the 5Dmk2. I have been wanting to get one for awhile but chose to save money on a vacation instead
but I do hope to get one around Xmas. I assume you have used it quite a bit so I am wondering how do you like it's AF?
I have heard people complaining about it and from the specs I have seen it seems to be inferior to the one in 40D/50D. Is it good enough for shooting wildlife and bugs?

The only drawback to the 5d mk II is the auto focus. It has the best AF I've seen on the middle square - even better than the 1d's (just woke up, nn technicalities), while the outer focus squares lack somewhat. Nevertheless, it takes some getting used to. I'm sure people complained about this in very low light or in non-contrasted settings, because it's not bad at all.

When do you Bsod? During startup? In windows? The settings i gave you, what frequency did the ram end up to be?



Noise are most apparent in dark areas (underexposing does that too.) Try shooting to the right a little when you're using a high ISO, bring it back in post.

I've taken tons of shot with my 50D at 1600.. it's perfectly usable. I sometimes do ISO2000 too, with a little noise reduction it's not that bad. But i have to admit ISO3200 is pretty worthless.



You know how Canon's AF algorithm works right? It's AF detects difference in contrast to lock onto a subject. For example, even on a bright day.. It's almost impossible to AF onto a completely solid color subject with no texture. As for AF performance on the 5DII, i'm sure it's good enough for wildlife and bugs since i've seen numerous shot of them from that camera, high speed action things such as sports is when it doesn't cut it. The AI Servo isn't as robust as the 7D or even the 50D.



Are all 9 AF points cross-type?

I found out about the AF points.

Lines of contrast are places where there is a clear definition between a dark tone and light tone. If you point you camera at a white wall and try to auto focus it will hunt like mad, but if you drew a black line across the wall and AF'd on that it would be pretty spot on.

You might be hunting because you could be on the verge or past the minimum focusing distance for that lens. My lenses hunt when I'm too close. What's it like when you are shooting something at more of a distance?

The AF is fine on the 5dII. There are many many many pros out there that shoot with them. The people who poke and prod the 5d II's AF are either making a fuss about it just have too much money to burn on a D3s or a 1dIV LOL If I can shoot in dark places with my 5d I and nail it 90% + of the time then the 5d II will be fine. How much low light shooting do you actually do?



When running LinX. Only got one try in then it BDOD. Temp was okay, 58 celcius. Ram freq was 1480 at the setting of 8 you gave me. Will the error be in event viewer?

It could be, check event viewer and see if you can get the bsod code.

For the time being.. set the ram to 9/9/9, i want to concentrate on the proc before tightening the ram timing.

Also can you download Prime95? And run the blend torture test, if it is unstable.. it will usually crash or bsod pretty soon. Try and see what BSOD code it gives you.

So set the ram to just 9/9/9 without adjusting the voltage, tras or trfc ? Then change everything like before?

I have Prime95. I'll run the torture test when I adjust the settings now.

Cheers

Yes. It was suppose to be 9/9/9

Yeah, not sure why it went to 7/7/7.. pretty dumb :/

Here's the error code from the first time:



Going to change it all now. brb
