Encase you can't access the link - ASUS M4A89TD PRO/USB3 AM3 AMD 890FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard

I just need some help figuring out what ram would be the best/fastest and that would work of course. I want DDR3 2000mhz or 1600 so if anyone has knowledge on this M/B please feel free to comment. I plan to order this M/B to upgrade my biostar which is older and only supports DDR2. (If you know of a better M/B for $200 or less feel free to post). I have always had great luck from Asus products so I prefer their stuff and Asus customer support is great.

I have a ATI 5870 1gb XFX GPU - 3.4ghz quad, II 965 black edition CPU - I run Windows 7 64bit.

Other thoughts; my hard drive is a western digital caviar black 700GB 7600RPMG 32mb. I was told my a friend my hard drive is bottle necking my machine! Does anyone have any thoughts on this as well? Thanks in advance!

Your hardrive is a standard sata II; most have 7200 rpms, so you're fine. The ssd's and western digital raptors are faster, but more expensive. Check the qVL ram listing on asus website for your board. It will list some tested ram you can choose from. I recommend 1.5v 1600 for value and performance. I use gskill, and it's priced right at newegg.

Unless you have a 6-core AMD CPU then don't get 2000 MHz RAM, and instead a low-tight CAS 1600 MHz -> http://www2.corsair.com/configurator/product_results.as... CORSAIR DOMINATOR 4GB (2 x 2GB) DDR3 1600 CMP4GX3M2A1600C9 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

ANY mechanical HDD is slow, Raptor or not, in comparison to current SSD. Once the data is loaded, it really isn't considered a 'bottleneck' in that the FPS are not effected, the maps are loaded which takes longer with HDD, some games continue to load some map data which do cause a 'pause'.

I suggest you go by the QVL list for your board. You can use 2GB listing for bigger size DIMM's and should be fine with that. Going with 2000 MHz RAM is a total waste of money IMO. As has been said, 1600Mhz is about right and you won't leave much behind going with 1333Mhz. Young people today are all about speed speed and more speed. Do they not realize the difference between 1333 and 1600 is about 3 frames per second? That cannot be seen by a human being so why spend the extra money and risk a BSOD or freeze up running with speed demon stuff? Intel wants people to use 1066 or 1333!!!!!! So, use your money for a second GPU or an SSD and go conservative on the RAM. You'll thank me later. :hello:

Only the 6-cores will support the 2000MHz, so it's not an option; Yes, you can run '2000 MHz RAM' BUT at speeds under Rated speed e.g. running 1800 MHz vs 2000 MHz -- but what's the sense in that?!

I get into the Frequency debate with people all of the time, and certain CPUs + MOBOs will limit the benefits; I really don't want to agonize over a debate.

Example, X58 - the IMC craps-out at ~2200 MHz RAM and the i7 9XX IMC is rated at 1066 MHz. To achieve 2000 MHz you need to raise the BCLK >= 160 in most cases to alleviate the IMC :: RAM disparity.

Example, AM3 6-Core 1333 MHz can handle the 2000~2133 MHz RAM frequency, but the 4-Cores cannot. Most MOBO Mfg's will disable the DRAM Frequency > 1866 MHz based upon the CPUID info. e.g. ASUS "The motherboard supports DDR3-2000MHZ DIMMs only when you install a 6-core CPU to the motherboard."

In contrast, the new SB {Sandy Bridge} 1333 MHz IMC CPUs see to hit a wall from benefiting from the RAM Frequency > 1333 even though they can run 2200 MHz RAM. This is like a Wall for those CPUs. Therefore, I either recommend 1333 CAS 8-8-8 or 1600 CAS 8-8-8.

Therefore, if there is no benefit then why spend the money. In this instance, ideally the Phenom II X4 'do' benefit from 1600 MHz, low/tight CAS RAM; in contrast {CAS to CAS; same IC} the gain can be 2~8 FPS gaming from 1333 CAS 8-8-8 / 1600 CAS 9-9-9 from the frequency gains alone. The better would be 1600 MHz CAS 8-8-8, but they're expensive for a quality IC.

Thanks for all the replies it was very VERY helpful. I am all about speed only because I want to be able to run the high demanding games I play such as Crysis and soon Shogun total war 2, and I like to buy whats best for the time that way I don't need to update sooner.

I will check my M/B list to see what my M/B can use but 1600mhz is probably the sure pick. Thanks again.
