What is the rev number for these memory? if the REV number is different from my existing (2*2GB)can that affect the performance?

Rev number should just be the revision number. Essentially like a batch number... if all the other specs match it should be fine. If im not mistaken

It should be fine, even if you mix and match ram from different vendors it will work fine if the settings are all the same.

I installed these two memory sticks next to two other DDR3 2X2 4GB sticks from another manufacturer and they've worked fine for the past year. There was a big improvement in performance playing the video game CIV 5 on the highest resolution after the RAM was increased from 4GB to 8GB with the addition of these sticks.

Both boarsd I ordered were rev 2.1, which claims to support DDR3-1333 memory. The box should say which memory types it supports though. I should mention though that I couldn't even get this board to POST, with either one I recieved. It seems to be VERY picky about your hardware configuration and would not boot no matter what I did. Your mileage may very, but just a heads up.

Please go to Crucial.com and install their tool. They will tell you what ram to use. It is a free utility, and does a wonderful and correct job. It has never given me the incorrect information. This is where everyone should start to select the correct ram. All I did, was gave a critical review of the ram I installed, at the recommendation of this utility. You can't go wrong.

Melder you might want to prepare as there is now a review on cnet.com where the reviewer states his unit comes with 1GB welded on and no way to update it to 2gb. Please post your findings when you get your unit and I hope the RAM is upgradeable!

Should work. This is ecc memory. If it doesn't work you can return it for a refund.

Ah! Cache, great, thank you for sharing this. I wonder if there's any noticeable read or write speed difference between 16 and 32 -- I was under the impression that 16 was quite a bit. Thanks again!

Jake,if you can check the Gigabyte website for a listing of memory types,if the you have is supported,then I would remove all but one, restart, repeat, until bad mods are found

It is best to pair matching memory. So you'll want to buy another 4gb stick if that's what you currently have. Make sure the frequency is the same too, the majority will be 1600MHz. If you want to be sure you'll need to look up manufacturers specs online for look on your existing memory or it might be on the memory itself. Hope that helps.

I checked the specs of your computer, you have a max load of 4gb. With 2 cards in there now it should be 1gb. So if you have 2 slots left, you could get bigger cards of 1gb for all slots depending in how much you need. Your serial shows its unbuffered ram. Look for PC2-4200 ram or DDR2 240pin SDRAM.Should be 533Mhz for speed. This is critical.

you would need to get the mother board spec sheet to see if you can upgrade your memory first, and also what kind of memory slots you have available. Or, take out a memory sim and record the make, speed, and slot type to replace with the same speed and type just make sure it's more.

thanks for the link, also about to purchase Ul20a with the memory you recommended, just wondering if its the same timings and specs than the one that comes inside.

I'm an end user so I have no idea. I think the vendor's website has the correct correspondence of machine to memory. It not, try Googling the memory for that machine.

Your computer uses PC2-4200 DDR2 memory. This memory will work on your computer. Please make sure you have enough available memory slots (2) for the new 1GB (X2) modules. If not, you could remove two smaller RAM modules and replace them with your new memory pair.

I have replaced my one gb stick of ram with a 2gb stick of ram. Hope that helps.

I am not sure about this with out doing a research. can check this out by doing a Google search about what memory will work.

See what type of RAM stick your computer has and match it to that. That is what I did when I upgraded to 2GB, also find out what is the maximum ram your computer can handle and upgrade it to that. Hope this helps you.

I found the information on the wrong memory I ordered. It is the same description as the one you are looking at with one exception; it is sold by a different company. Point out the error in the description to Amazon and they should give you a full refund including shipping. They did me. That is, if your computer is listed in the description.
