Gam55plus-s3g Memory does not recognize correct size.

For some reason my Bios will not recognize the correct amount of RAM. I currently have two 2-gig sticks, 4 gigs total, installed in the 1 and 2 slots of the mother board (yellow slots); i have tried all different orders to no success, the bios still shows each stick as 1 gig rather than 2. I have loaded the fail safe in the bios and disabled video (i have a video card). the memory I am using is model PSD22G667K: Patriot Signature 2GB (2x1GB) DDR2 667MHz (PC2 5300) System Memory Kit PSD22G667K, 240-Pin, CL5, Non-ECC, Unbuffered, RoHS Compliant. I am running a 32 bit OS currently, but I would expect that the OS shouldn't affect the bios. My bios version is F1 for the m55plus-s3g

PSD22G667K is a kit that contains two 1GB modules; therefore there's nothing wrong with your system.

So what is the purpose of a two gig stick, ie; one stick that = 2 gigs, if it won't be recognized as two gigs? I also have a 1 gig stick of the same make. What i mean is, what is the difference between a 1 gig stick and two 1 gig modules on 1 stick? Further, what type of RAM should I be looking for in order for my bios to recognize more than 1 gig of ram per stick?

Thank you for the reply.

Let me add to this a little bit. I am getting ready to install a 64 bit OS and am wanting as much RAM to reflect as possible for best results. I was hoping to utilize the RAM I have and possibly adding 2 more gigs or so then upgrade to a quad core processor or similar. However, I am currently running a 64 bit processor (AMD Athlon 3500+ 2.20 GHz) and may use that for a while.

That said, what type of RAM should I be running for best results? Is the RAM I currently have sufficient? It only shows as one gig per stick because, apparently, the RAM has two 1 gig modules (which I don't understand since it still reads as 1 gig). Is this beneficial, or should I look for true 2 gig sticks for my motherboard? I am not very familiar with dual channel or what it does and this site seems to be full of smart individuals capable of assistance. Thank you for the replies.

Thank you, GhislainG. I know now what I did and frankly am quite embarrassed about it. When I purchased this RAM it even stated cleary "2 gig" on a sticker, but I am sure now that it is 2 gigs total for both. It shouldn't be that unclear I must say. Thank you for the links. I shall begin with those to search for more RAM. I am trying to make this 64 bit OS as smooth as possible.

I do have one other question for the experts. Is it possible to mix different sizes/speeds of RAM so long as they're not in the same group of Dimms? For instance, could I put 2X2 gigs 800mhz of ram in Dimms 1 and 2 totaling 4 gigs, then put 1X2 gigs 600mhz in Dimms 3 and 4 totaling 2 gigs, making my system totaling 6 gigs, or would that inhibit the performance of said RAM?

They'll run at the lower speed (667 MHz) and timings. While they'll probably work fine, I wouldn't recommend mixing and matching memory modules.

Thank you, GhislainG. As a final note/question, I have finally decided to upgrade based on my motherboards capabilities. Please let me know if these two upgrades will be worth my troubles:

Currently I am running an AMD Athlon 64 Processor 3500+ 2.2 GHz, with the RAM described above, 2 gigs of DDR2 667MHz (PC2 5300) System Memory Kit PSD22G667K, 240-Pin, CL5, Non-ECC, Unbuffered, RoHS Compliant.

I want to upgrade to:

AMD Athlon X2 5000+ 2.2GHz 2 x 512KB L2 Cache Socket AM2+ 65W Dual-Core Processor (link: http://www.newegg.com/Product/Product.aspx?Item=N82E168...), with this RAM: 2 packs of G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel (link: http://www.newegg.com/Product/Product.aspx?Item=N82E168...).

Would this upgrade make a considerable difference in my performance? I have checked my motherboard and this all seems to be supported.

Thank you for the assistance. I do believe this will be my last question.

You provided a search page for the G.Skill memory. Please provide a link to the specific memory you plan on getting.

The new CPU should be substantially faster, but you can check http://www.tomshardware.com/charts/cpu-charts-2008-q1-2... as we don't know what applications are most important to you.

My apology:

I am unable to post the link correctly, but it's the first G Skill RAM link you post previously:

Does it read as 1GB total or as 2GB total? A 2GB kit is two 1GB modules; not two 2GB modules. If you want 4GB, then buy a quality kit like:

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Basically you should buy DDR2-800 modules that run at 1.8V-1.9V.

They should be fine, but set the voltage to 1.9V when using 4 modules.

That works. Thank you for the assistance. I am hoping to achieve a nice performance boost. I am not a gamer, but I like to have a quick system especially since I am about to upgrade to a 64 bit OS.
