NEED REPAIRS. Posted February 23, 2007 Posted February 23, 2007 Hey guys, I just recently replaced my old MSI RS480M2 motherboard with this one for obvious reasons... and I can't get it STABLE!! It keeps rebooting on me randomly. On Windows install it reboots, after about 3-4 tries, I finally get it installed, and it just reboots on desktop. Or it just freezes! I've flashed to latest BIOS and loaded optimized defaults, have ran memtest86, and am not overclocking anything..yet. Any help would be greatly appreciated. oh yea and all the hardware has been used and works flawlessly on the RS480M2(except my USB 2.0???)

izark Posted February 24, 2007 Posted February 24, 2007 I'm new here but I would first suspect the PSU as your output of your PSU is 26a on the 12 v rail. I was reading another post and it said that 33a on the 12 v rail was cutting it close. Here is a link to a thread on good PSU's for DFI boards http://www.diy-street.com/forum/showthread.php?t=73137 Quote Share this post Link to post Share on other sites More sharing options...
NEED REPAIRS. Posted February 24, 2007 Posted February 24, 2007 33A??? are you kidding? Quote Share this post Link to post Share on other sites More sharing options...
CPDMF Posted February 24, 2007 Posted February 24, 2007 First thing out of everybody's mouth is Power Supply. The modstream you have is plenty for the equipment you're running. The CFX3200 has some crap default memory timings. They are memtest stable but that is about it. It's not a board for the faint of heart and will take some time and tuning just to get it to run at stock speeds. Change Tref to 3120, Max Async to 7.0 and Read Preamble to 5.0. I'm not familiar with your RAM but I am very familiar with the CFX3200. Might want to play with Drive strengths between 5 and 8 as well.

Guest Lavell Posted February 24, 2007 Posted February 24, 2007 No, he's not kidding. These boards require some serious power. If you was running Crossfire, you would be looking at least 30A. With the configuration you have now, that PSU is barely getting you by. If there's 1 piece of computer equipment that every builder should go overkill on, it's the PSU. I recommend shopping for a 600W PSU. And don't get power supplies that have too many rails. In my opinion, three 12V rails is enough. Any more than that and you're asking for trouble. 33A??? are you kidding? Quote Share this post Link to post Share on other sites More sharing options...
CPDMF Posted February 24, 2007 Posted February 24, 2007 If the CFX3200 requires 33 amps with a Venice and an X850 I'll give you one of my rigs! That enermax you have only has a combined rating of 36 amps.. Quote Share this post Link to post Share on other sites More sharing options...
NEED REPAIRS. Posted February 24, 2007 Posted February 24, 2007 im with this guy. no way in hell it requires more than 26A with an x850 Quote Share this post Link to post Share on other sites More sharing options...
Guest Lavell Posted February 24, 2007 Posted February 24, 2007 I've edited my post to reflect some changes. Quote Share this post Link to post Share on other sites More sharing options...
CPDMF Posted February 24, 2007 Posted February 24, 2007 While I agree with you on a quality power supply being critical to a good build I disagreed with what you first stated as a requirement for his particular situation. I run good power supplies, I have owned 2 CFX3200's and have had 4 in my possession over the last 90 days for different reasons. A DFI board will not consume any more power by itself than any other motherboard, if it did that would be a very poor design that would not be efficient and probably wouldn't clock very well. They place power where it needs to be to give the components the cleanest source of power available. As far as the 450 watt Modstream goes, it is very high on my list of quality built PSU's, better built than my 700watt OCZ as far as quality is concerned.

NEED REPAIRS. Posted February 24, 2007 Posted February 24, 2007 So here's the news.. I took out my psu and put my friends mushkin 550200 550w and installed windows without it rebooting on me. I then took it out and reinstalled my OCZ 450 modstream and ran prime95 for about 8 hours and no reboots! Its been up ever since without any issues. I even went ahead and installed all my windows updates and what-not. So i'm thinking maybe it was just a faulty connection between my PSU and motherboard somewhere, even though i tried reconnecting everything prior to this, but who knows??

izark Posted February 24, 2007 Posted February 24, 2007 NEED REPAIRS, Good to hear all is well. As you may see this was my first post, (and very likely my last for a while). I was just trying to be helpful, and i certainly was not trying to start a brawl. I will do more research before helping again. Glad to see everything worked out for the good.

NEED REPAIRS. Posted February 25, 2007 Posted February 25, 2007 no harm done man, if i came off like an butt, then i'm sorry it wasn't my intention haha back to the motherboard.. it did freeze on me ONCE so far but it didn't restart gonna maybe set memory timings manually Quote Share this post Link to post Share on other sites More sharing options...
