I recently got some DDR RAM as a gift for my gaming unit.  Thing is that when I put it in the Dimm it beeps like there isn't any when it has 1 GB.  I tried the memory in another unit an works fine.  Its the same as the other with the exception of size.  Ultra DDR PC 3200 512 MB, Intel SE7210TP1-E Sever Board.  Not sure if it has too be in pairs or not.  I also tried it in the other slots as well as TAKING out the 1 GB an just Turing the 512 MB.From your description i am NOT certain if you have tried the following so i shall ask the question. Have you tried the single ram (the 1gb) stick in any of the available ram slots by itself? If so what was the result ? Yes there are instances when the ram sticks will not function if they are not installed in pairs. So the fact that you have the old  512 and the new 1 gb in together COULD be the basis of your issue. Also some instances of installing RAM of different brands can also create your issue. As i reread your post i am now not sure whether it is the 1 gb that is new or is it the 512? truenorthIf it works with 1 512 then the machine does not require it to be installed in pairs ...so that's not the issue.

Most LIKELY a case of mis-matched RAM...I have tried the 1 GB an that is what I have been useing.  Some games require a lot of extra files that I added an seemed like it needed
too take the strain off the CPU.  I never said the 512 was old I just got it.    There the same brand an EVERYTHING except for the capity.
Considering the board I dont know or not since I have four Dimms.
OK...you lost me....Me Too ,truenorthi am simply adding the 512 so that the cpu doesnt have too be strained when loading things such as my sims 2 stuff.OK i think i have the picture now. The 1 gb was what was originally in the computer. You believe that you needed to increase your RAM capacity so you installed a 512 MB additional stick. Correct? Now the question is when you "tried" the 512 by itself--did it work? If not then assuming you are correct when you say it is the same in all regards other than it's "capacity" you have a defective 512 RAM stick. truenorth
P.S. Although if it has not been verified i suppose it is also possible that the slot you are trying to use for the 512 could be defective however that is easily verifiable by moving the 1 gb stick to it and seeing whether it works or not.Yes, too allow this unit to process faster.  No, which I don't get really why.  That's partially what I was thinking then as I had previously
stated it works in another unit seemly just fine.  Probably should run the mem test?  I tried two different dimm slots though.  Your replies are vague and making assistance very difficult. As an example what is it your answering with this " No, which I don't get really why." ? Is that in reference to yes you did try the 512 by itself and it did NOT work and you "don't know why". But apparently when you move it to another computer it DOES work fine. Which points to a mismatch with the ram sticks if you have eliminated the possibility that the RAM slots are defective.truenorth Quote from: truenorth on January 01, 2011, 08:16:10 AM

Only if you value your sanity.
