Well, I've had my AMD phenom 2 for over a year, and have recorded an antire album plus many other things with it

the specs

AMD phenom 2 x3 720 (2.8)
8gb ram (gskill ddr3 1333)
windows 7 ultimate 64bit
gigabyte mobo
1tb HD (2 500gb disks)
Juli@ recording interface
ATI XFXforce 4890 1gb video card

OK, so the thing is that I've been recently having the horrid blue screens and the system crashes with no previous warning: you're doing anything (from typing in Word to recording in sonar) and everything goes to hell, blue screen and restart. most of the times the message I got was MEMORY_MANAGEMENT

this started some months ago, sporadically, but now it's just unbearable, Windows starts and I get problems with explorer, the Catalyst program (from the XFX radeon 4890 video card) and so on so forth, now it's at the point in which I can scarcely do anything except in safe mode

I've looked into this, browsed forums, many said that it could be a problem with drivers (I've recently updated the video one to the latest, checked hard drive issues, but nothing). I still have to try moving the memory sticks from one slot to a different one (I've even read someone solve the problem this way) and have also tried removing them, disconnecting the pc and pushed the on/off button. this seemed to work a couple of days ago, and I was able to use it for hours, but then again yesterday I started the system and there we went again...

the only hardware change I've had recently was upgrading from 4gb ram to 8 (I had 2 2gb sticks, now 4), but I got the same type, same make, different model though. and some weeks ago I thought THIS was the problem, probably faulty ram (the new one), but after removing them, hell broke loose nevertheless...

any opinions/suggestions? has this happened to anyone? I'm desperate!

Some RAM, even with the exact same specs, even the manufacturers, simply doesnt play well with others. Both of my macs had the same problem. When I went to a single manufacturer, exact same speed, it all stopped and no problem since.Another thing to look at is the RAM speed. If you have added ram that has a different throughput than other ram already installed you are creating a bottleneck. Sometimes the rearranging of the sticks will solve this.

All of the above is correct. If this started when the OP swapped/added ram modules then that is the place to start. To assume because a DDR chip is new that it is not the problem is poor trouble shooting. That is the FIRST place to start. Also, if the ram chips mismatched substantially and Win7 attempted to do some funky things to counteract the mismatched chips, a fresh install of the OS may be in order.

That is very curious. On modern recent motherboards it is highly unusual to have slot order issues at all. IRQ numbers can be assigned from BIOS whereas before it was difficult or impossible to truly change the IRQ assignment. My best guess is two of your cards were sharing the same IRQ and attempting to operate simultaneous control. By switching to a slot that coincidentally had a different IRQ then you may have alleviated the issue.

do you really think it could be simply a matter of dust or sth the like? I haven't looked at the modules up close (didn't even bother) but will if that's what you suggest...
still, I my best guess is it's a compatibility issue. I've recently removed the NEW ram modules and the system seems to work better: so far no crashes, but a few minor issues every now and again, noth serious.

the new modules are gskill ddr3 1333 (4gb), but a different model from the original ones...

should I return them? change them?

This sounds to me like the timing on the new modules is not recognized by the motherboard. Not all ram modules have automatic timing adjustment. This would definitely cause problems. Check the timing on the old modules and what is recommended by the manufacturer. If the new modules match those specifications and provided you haven't hot rodded the bios, then they are simply bad modules.

As Jack says, that is an indication that either (1) the new modules are faulty or (2) your motherboard does not support the specification of those modules.

Either way, there is no point in persuing the investigation, with the possible exception of seeing whether there is a later motherboard BIOS available with revisions to support more recent memories.
