MindBlank Posted April 3, 2006 Posted April 3, 2006 Hi! This is my first DFI board. I had a pretty rough time making the board run in the first place... I forgot to connect all 4 power suplies and the board didn't start (i got 3 LEDs as an error). Anyway, i got it running but so far i haven't been able to make it run with all my 3 memory modules. I have 1x512 MB Canyon (piece of [email protected]) and 2x256MB Spectek (double piece of [email protected]). It seems to start with either two, but not with 3. I've also tried putting them in different DIMMs and haven't had any luck. I then set the DRAM frequency at 133 from the BIOS and it still doesn't boot up (i get 3 LEDs). I will now try to set some very loose timings, but i imagine i'll have no luck. I have to mention that i haven't had any problems with these modules in an MSI K7N2 Delta-L (nF2), a Gigabyte K8NS Ultra-939 (nf3). Does anyone have any suggestions for me? Am i doing something wrong? Share this post Link to post Share on other sites More sharing options...
CPDMF Posted April 3, 2006 Posted April 3, 2006 3 dimms won't work no matter what you do. This is a limitation of the CPU's onboard memory controller, not the board. Share this post Link to post Share on other sites More sharing options...
lawrywild Posted April 3, 2006 Posted April 3, 2006 3 dimms won't work no matter what you do. This is a limitation of the CPU's onboard memory controller, not the board. I think it can @ Single Channel and 2T Share this post Link to post Share on other sites More sharing options...
cmay119 Posted April 3, 2006 Posted April 3, 2006 So you're trying to get 3xDimms working at the same time (which is already hard on the Mem, controller as it is). Then on top of that you're using unmatched sticks. And then on top of that, your using high density value ram. Perhaps if the Mother Mary comes down from the heavens and gives them the holy touch, then "maybe" your computer will boot up. Anything short of that, and I think you're in for some headaches. Count your losses and run the 2x256 until you can get some better memory... Share this post Link to post Share on other sites More sharing options...
Sharp Posted April 3, 2006 Posted April 3, 2006 Hello, I suppose you have tried these combinations? Top Orange slot = 512MB Top Yellow slot = empty Bottom Orange slot = 256MB Bottom Yellow slot = 256MB and this, Top Orange slot = 256MB Top Yellow slot = 256MB Bottom Orange slot = 512MB Bottom Yellow slot = empty If it doesn't work there is not much that can be done. Just because it worked in the MSI/Gigabyte board doesn't mean it should work in this board. Share this post Link to post Share on other sites More sharing options...
DrNick Posted April 3, 2006 Posted April 3, 2006 I think it can @ Single Channel and 2T How can you run in single channel with 3 sticks? Share this post Link to post Share on other sites More sharing options...
madu Posted April 3, 2006 Posted April 3, 2006 3 sticks will not work probably.Well it wont to best of my understanding. If you are using either slot #3 or #4, you need to have sticks in slots #1 or #2, respectively. Bottom slots are used for dual channel. If you have ram sticks in the same colored slots, it will run dual channel. ram in slots #1 and #2 will run single channel. But if you have ram in same colored slot + in either slot #3 or #4, which mode should the cpu operate in?? Single or dual channel? Also if need to same same ram in the same colored sticks to run dual channel, or you 'll get problems. So if you still wanna try, try the 256 sticks in orange slots, and put the 512 in slot #1. I dont think it will work, in case it does, please post back! Share this post Link to post Share on other sites More sharing options...
syar2003 Posted April 4, 2006 Posted April 4, 2006 Rev E athlon 64 and later supports mismatched memory . Eg 2*512 in each channel (A+B) + 1G in the other channel (A) Result is that the CPU sets all in 64bits mode (single chl mode). Ref: Bios and deveoper guide Athlon64 New: mod64bitmux register , "Mismatched DIMM Support Enable" Don't know if DFI has coded this in their bios though , but it works on other boards Share this post Link to post Share on other sites More sharing options...
CopyNinjaKakash Posted April 4, 2006 Posted April 4, 2006 yeah i was wondering about something similar to this the other day too.. if i got 2 more sticks of 512 OCZ could i run them in dual channel along with the ram i have now.. or would that just not work?

madu Posted April 4, 2006 Posted April 4, 2006 so if you have two mismatched rams in the same colored slots, will it run single-channel? I dont think the DFi works with that.. atleast my ultra-D doesnt. Share this post Link to post Share on other sites More sharing options...
cmay119 Posted April 4, 2006 Posted April 4, 2006 Even if you do get it to work. It sounds like it's just the combination for trouble. Mismatched sticks + different sized sticks + 3 slots + AMD Memory controller. Looks like migraine central coming up... I've never tried it personally because I didn't want to deal with the issues that would more than like come about from it. Share this post Link to post Share on other sites More sharing options...
MindBlank Posted April 4, 2006 Posted April 4, 2006 OK, i'll try some of your solutions and post back with the results. I have one more question though : if i get another 512 stick and use the two 256MB sticks in Orange/Yellow and the two 512 sticks in Yellow/Orange will it work an will i have any problems?
