Hi, i'm currently upgrading my system, and i'm changing the mobo and rams, the memory i'm gonna buy is 1600mhz, i heared there's no big difference from 1333 to 1600, but anyway, i'm confused about this 2 motherboards for the memory support and future cpu supports:

this 790x board that supports 1333, 1600, and 1800 oc
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

and this one that supports 1333 and 1866 for oc but it has a new chipset that may have a better supporting for future cpu like the amd bulldozer!

thanks so much!

I looked at both of the AM3 MOBOs and there are more differences than native DDR speeds. In general the budget and use determines everything which should be decided upon first. As a "reality" check unless you're adding a SATA3 SSD/HHD/HDD or have need for USB 3 those add-ons on non-X58 will impact the MOBO's bandwidth. I too assume the you do NOT want to run SLI and instead prefer CF. -> all checking first {Q & A}!

If you plan to OC then you should go the 1600 MHz speed for either of those MOBOs, and anything faster is money wasted. In order for any of the listed DDR to work beyond 1067 MHz Automatically with their native speeds the DDR must come from the MOBO's XMP/QVL Approved list which is very sparse and not required.

Next, working backwards once the MOBO is finnaly selected I then cross-reference the Approved list and/or I use the Mfg (Corsair, G.SKILL, Mushkin, or Kingston) and verify compatibility using their Configuration link to the MOBO.

Hope this Helps!

If you want to get USB3 and SATA 6GB support buy the Gigabyte one, if not get the ASUS. There is not going to be any memory performance difference, both are quality boards.

OC works better with 1600 MHz, performance ~ +1 negligible.

Thanks guys, but will the 890gx support 1600 without oc, coz i think the 790x will support 1600 without oc, isnt that true?!

In order to achieve 1600 MHz you will need to in the {BIOS} manually set at minimum the Memory Multiplier, CAS timings, and perhaps the DRAM Voltage {e.g. Round Down (1600 Memory Multiplier / 133.33 BCLK) = 12 and the CAS timings e.g. 9-9-9-24}.
Support for DDR3 2000(OC)/1333/1066 MHz memory modules -> 1600MHz is not a native DDR speed for this MOBO, but it can run 1600 MHz if set in the BIOS.

As I stated "In order for any of the listed DDR to work beyond 1067 MHz Automatically with their native speeds the DDR must come from the MOBO's XMP/QVL Approved list which is very sparse and not required."

Hope this answers your question clearly enough.

The "Zambezi" CPU isn't released yet, and I haven't seen any final whitepaper on the AM3+ socket. Guesses and rumors have been backwards compatibility with current AMD3 CPUs on the "AMD3+" socket, and mention of support for PC3-12800 (DDR3-1600).

That all is if you want to wait and see, you cannot build on vapor-ware whether it be in the form of H/W or software.

+ @zipzoomflyhigh is correct and I completely overlooked flew by the Bulldozer reference.
