OK, I am a little confused. I have searched this site on GDDR3, and have found articles, but not answers. Maybe I am just slow. But, here it is. I bought an Acer Veriton X275 desktop PC. Actually, I bought it for my boss. We wanted a little upgrade, so I went to Crucial.com and did their scan. Their scan told me I could purchase a 4GB kit, DDR3 PC3-12800 unbuffered, Non-ecc 1.5v.

I took that info and purchased G.Skill DDR3-1600, 1.5v, PC3-12800. After installation, I get one long beep, nothing on the monitor. I have tried re-seating, installed both modules, swapping spots, one new stick and the old stick, etc... Always one long beep. When I go back to the original stick, everything works fine.

Looking at the old stick, it says GDDR3-1333, 128mX8. GU512303EP0202. Did crucial steer me wrong, or do I not understand something when I transferred the information to newegg?

Also, it may be worth noting that when I first opened the case, it was only that one stick, and it was in the DIMM2 slot. If you only use one stick, isn't that supposed to go into the DIMM1 slot?

Any help avoiding looking like a dumbass to my boss would be appreciated.

Crucial didn't steer you wrong, you did.

Not all memory is compatible with every motherboard, it is very specific.

Crucial recommendation was only for Crucial memory, any other memory is a crap shoot.

If you wanted a choice of brands, you should have gone to the motherboards web sigh, for their compatible memory list.

GDDR3 is graphics ram thats what the G means its usually inside a graphics card. Your saying you have a stick of ram that says GDDR3 on it?

Yeah, it literally says GDDR3 and was installed by the factory. I can post a photo in about an hour or so. The camera on my phone won't take a clear enough photo to post here at work. That's what threw me off. I always though GDDR was installed for graphics and was soldered to the board. The PC is over 3 years old, and is out of warranty. Acer doesn't want to help me at all. So, is crucial usually correct? Can I trust their scan for this even though the G is throwing me off? Could the G possibly be related to the maker of the MB?

It was more than wanting a choice of brands, it was trying to find a better price.

Since getting burned several times,20 years ago, I always check for compatibility.

I have never heard of a board maker, or a memory maker, giving bad info.
They actually test each stick they recommend.

I did get burned a few years ago because I trusted a review on New Egg.

If I had just read the next 5 reviews, I would have found out all 5 were burned by the same idiots review. all 5 also had the correct memory posted.

As others said, the RAM specification definitely isn't wrong, it just depends whether your motherboard supports the RAM you bought or not, but generally the RAM will be downclocked to DDR3-1333 if the board doesn't support 1600MHz.

"Also, it may be worth noting that when I first opened the case, it was only that one stick, and it was in the DIMM2 slot. If you only use one stick, isn't that supposed to go into the DIMM1 slot?"

-Not always true, especially when it comes to dual-channel pack memories. There were two or three times when I had to try a single stick in every slot until the machine turns on and post before being able to install the second stick. So I would recommend keep trying all slots with either stick until it posts, should only take 8 tries. If you already did that and no result, put your old RAMs back, update BIOS, then shut down and try the step before again.
