ASUS M5A99FX PRO R2 RAM Overall Rating

Archean_0-1354672 · Oct 1, 2013

I've heard/read that the board only recognizes 1333 Mhz Ram despite that the board is advertised as 1866 Mhz with 2133 Mhz (OC).
Is this true? How is this board, in general--it would be used with an FX-8350.

Are there any similar motherboards with the same/better specs?

Tradesman1 · Oct 1, 2013

It's a very good mobo, and not sure where you heard that on the DRAM, it defaults to 1333 when sticks are first installed you can simply set them to 1600 or 1866 depending on what you get and it can run it fine, and should be no problem with an 8350 (up to 2 sticks anyway, that's what the 8350 is rated to, 2 sticks of 1866), 2133 might be tough

(going for 16GB in the long run) would 2x 8GB work better or worse than 4x 4GB? I don't know very much about RAM--like CAS, voltage ratings, etc.

Tradesman1 · Oct 1, 2013

2x8GB would be better, less stress on the MC (memory Controller), might look at GSkill 2x8GB Snipers, in 1600/9

or 1866/9

My current [virtual] build has

Memory: Kingston Blu 8GB (2 x 4GB) DDR3-1600 Memory ($69.75 @ Outlet PC)
SPECS: http://www.newegg.com/Product/Produ...-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=

is it decent RAM? how great would the level of performance be between the 3? (the sticks I choose vs the ones you have)

Thanks : )

Your's are 1600/9 same as the 16GB set I suggested so basic performance is near equal, w/ 16GB overall performance may increase with the additional memory depending on what you do, one note on your current sticks, those are rated at 1.65, which I don't normally recommend for basic 1600/9 sticks, can be indicative of weak ICs, (why does it need 1.65 to run entry level DRAM? only about 12% of 1600 sticks need 1.65, just don't understand why they do that, it also cut's in to OC ability if thinking of OCing the DRAM

Archean_0-1354672 · Oct 1, 2013

I don't know much about OCing [RAM] (the last pc i built was in the late 90's), but if there are any similarly priced RAM sets that would offer same/better perfomance--I'm all ears

is 1.5V the standard for 'lower class' RAM?
---
does lower voltage mean it would [should?] have more overhead to work with when OCing?

Tradesman1 · Oct 2, 2013

1.5 is by far the most common for 1600/9 sticks, even for 1600/8 (better performance with the CAS of 8) are you looking for 2x4 or did you want 2x8GB?

Archean_0-1354672 · Oct 2, 2013

besides system stress, whats the difference between getting 2 sticks vs 4? just price?

Tradesman1 · Oct 2, 2013

Two sticks may run a hair faster (not that you'd notice), some will tell you it allows for upgrading in the other two slots, though I recommend against doing so, mixing DRAM can be problematic

Archean_0-1354672 · Oct 2, 2013

would i be better off getting a 2 stick kit and then buying the same kit 5 or 6 months later or should I just save up look for a [cheapish] 16GB kit?

Tradesman1 · Oct 2, 2013

Best to always get all your DRAM in a single set/package, that way it's tested for all sticks to play together and if 1600 or better, the XMP is programmed for that set of sticks

Archean_0-1354672 · Oct 2, 2013

any good 16GB recommendations? I know Toms just did an article about choosing a 16GB kit, but i figured i'd ask you while i also look around
---
the 2 RAM kits I came across

Patriot Viper 3 | 4x 4GB http://pcpartpicker.com/part/patriot-memory-pv316g160c9qk @$89.68 <NCIX.com>
^just checked NCIX.com, its back ordered, so current price is $144.99 <Amazon.com>

Mushkin Blackline | 2x 8GB http://pcpartpicker.com/part/mushkin-memory-997069 @ $120.00 <Newegg.com>

Tradesman1 · Oct 2, 2013

Either should work, I've had best luck on AMD with the Snipers, but as said, the sets you show should be fine

Archean_0-1354672 · Oct 2, 2013

awesome

Thanks for the help : )

Tradesman1 · Oct 2, 2013

No problem, let me know how the build goes

Archean_0-1354672 · Oct 2, 2013

Will do : )

I should* have everything put together by mid to late november...maybe sooner : D

*$ [tuition and rent come first]

Tradesman1 · Oct 2, 2013

Know how that goes, I'll be around (I hope
