guys, any tips for a nice setup? i just want to edit these AVCHD vids. currently my x2 3800+ is struggling just playing back the files

im looking at the AMD Phenom II X4 955 for the CPU

MSI 770-C45 AM3 AMD 770 for the mb

im not sure if the MSI is good enough. looks like most people are using the ASUS or the Gigabyte MA790XT-UD4P

im hoping to OC it to 4ghz and that should be fast enough right? also, what ram would you recommend?

as for vid cards, im thinking the HIS 4670 is perfect because it is fanless

Heya,

You're not going to get to 4Ghz very easily. Some can get there, but the chip really has to be a good one, and you won't know that until you have it. Also, the motheboard matters big time when it comes to these massive overclocks. Also, the memory you buy matters. Get the idea? Overclocking to 4Ghz is going to be an endeavor. You have to really be selective with it all. It's going to be expensive in the end. And that's kind of counter-intuitive being that you likely went AMD to save a buck.

I would suggest you rethink your goals of the overclock.

Get the MA790FXT-UD5P. Add the 955. Add a Mugen 2 if you want to stay cheap and hit 3.8Ghz on air. Go TRUE, Megahalem or Corsair H50 if you want to get more expensive (and not necessarily hit higher than 3.8Ghz). Get two sticks of DDR3 1666 ram with low timings. In BIOS, down clock the memory to 1333 and set the timings to around 7-7-7-20 (Gskill, Corsair, OCZ, Mushkin). Don't go above 1.55 on the vCore, and don't consider it stable if it can't do a 24/7 burn in with Prime95 and not break 55c on the CPU load temp at that overclock. You should be able to do this and get 3.8Ghz with relative ease; maybe 4.0Ghz if you really work at getting your frequencies, timing and vcore with the multiplier set perfectly (which can take days to slowly test each and every combination of options to find something that works and is stable at 4.0Ghz).

You can hit 4.0Ghz right away, but it doesn't mean it's stable. You've got to test it extensively to make sure it doesn't just crump and shut down the moment it hits too much load and overheats. This is why you need to test it with things like Prime95 that will really hammer the CPU and keep it at full load; burn in test should be in hours and it's popular to do a full 24 hour burn in to test it. If it can complete a full day's worth of work at full load without crashing and without fail, you can call it stable.

Very best,

strange, i couldnt find any DDR3 1666 ram

DDR3 1600 is the closest number i could find

Oh it's not strange; I simply meant 1600, lol.

Note, don't get the 3 stick pack. You won't use it optimally. Only the i7 uses tri-channel DDR3. The other boards, like AMD, use dual-channel DDR3. So you would use sticks in pairs, so 2, 4, 6, 8, etc. i7 Boards would want to use groups of 3, so 3, 6, 9, 12, etc. And when it comes to overclocking on an AMD, you're better with just two sticks of RAM to make it easier. More sticks equals more energy needed and it can affect your ability to get a higher overclock when you start raising voltages.

4Gb of good DDR3 1600 memory with low timing will be fine unless you're going for extreme overclocks (in which case, you'd be using an i7, not an AMD).

Very best,

I would suggest you avoid that MSi mobo if you are gunning for very high over clocks. I have not seen or read any on forums MSI 770-C45 AM3 hitting very high clocks and being stable.

Gigabyte seems to be the best mobo for Am3 right now .. !
