peace Posted November 1, 2009 Share Posted November 1, 2009 Hey. I'm going to buy 2xE5520 in Supermicro box, and wonder what RAM to choose ECC registered, ECC unbuffered or non-ECC. Does any of you have experience with such RAM and what advantages and disadvantages? Thank you. Link to comment Share on other sites More sharing options...
proclan Posted November 1, 2009 Share Posted November 1, 2009 You need to check the mobo specs some boards only run with certain memory. Link to comment Share on other sites More sharing options...
Steven Crothers Posted November 2, 2009 Share Posted November 2, 2009 The 5520 dual setup is going to require a bunch of power, don't forget about that. 2x 5520's 2x HD's Add a CD-Rom drive, your going to easily push 1.5-2 amps, also don't forget about when you push that power button your going to get a slightly higher spike than your average running amps. You don't want to trip your circuit Link to comment Share on other sites More sharing options...
Santino Cid Posted November 2, 2009 Share Posted November 2, 2009 A good amount of the boards that support dual 5520s will want ECC. Now you need to decide if you want registered or unbuffered. This also is pretty simple. If you are going for a large amount of RAM, go with registered. If you are going for a small amount of RAM, you can go with unbuffered. (notice those are worded differently) I recommend going with registered either way. If provides better communication between the DIMMS and allows greater RAM capacities, per DIMM and across the motherboard. Link to comment Share on other sites More sharing options...
peace Posted November 2, 2009 Author Share Posted November 2, 2009 Thank you for helpful reply. And what about performance in both unbuffered and registered memory for GSP? At this moment i stoped with 6x DDR-III DIMM 2Gb <PC3-8500> ECC Registered with Parity CL7. Is it nice choice or there is something better around DDR-III?

Santino Cid Posted November 2, 2009 Share Posted November 2, 2009 Unbuffered is slightly faster than registered. Registered will give you some more stability. Unbuffered will give you some more speed. These performance increases are not black and white, as like they are with HDDs. They will be rather slight. Exactly, what SM motherboard are you looking at getting for this setup? Link to comment Share on other sites More sharing options...
Derek Posted November 2, 2009 Share Posted November 2, 2009 Just go with ECC registered if you can as it's alot cheaper and you don't want to go with FB-DIMM. This is perfect: http://www.newegg.com/Product/Product.aspx?Item=N82E16820134652 Link to comment Share on other sites More sharing options...

In which case, two of either of the following will suit him best: DDR3 1066 (PC3 8500) http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2010170541%201052345114%201052429231&name=DDR3%201066%20%28PC3%208500%29 OR DDR3 1333 (PC3 10600): http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2010170541%201052345114%201052429248&name=DDR3%201333%20%28PC3%2010600%29&ActiveSearchResult=True Link to comment Share on other sites More sharing options...

In regards to op I would go with this of course if your mobo supports it. http://www.newegg.com/Product/Product.aspx?Item=N82E16820139055 Link to comment Share on other sites More sharing options...
