what is the fastest ram for the asus f2a55-m lk

[Russ6162]

I am currently using the AMD A10-5800K APU.
I am considering upgrading the APU to the AMD FX 8320.

Going to a 8320 with what mobo - these use different mobo sockets and DRAM capabilities are different - your mobo is rated up to 1866, the 990X mobos (latest for AM3+ can run 2400)

Hey Tradesman1,
Thanks for responding.
I currently have the ASUS F2A55-M LK mobo. (I threw out the box and have the manual * stored * somewhere...)
It appears that my mobo has the FM2 socket which only supports up-to a quad-core APU.
I just went to the ASUS site, looked up my mobo again and saw I had previously missed the "specs" link.
The site offered this information on RAM: "2 x DIMM, Max. 32GB, DDR3 2400(O.C.)/2250(O.C.)/2200(O.C.)/2133(O.C.)/2000(O.C.)/1866/1600/1333/1066 MHz Non-ECC, Un-buffered Memory ".
Does the "2400(O.C.)" indicate that the DDR3 RAM is running @ 2400 MHz (and what does the "(O.C.)" mean)?
Thanks again for the help, M8!

If they say on the site it supports 2400 then should be good there, could look at 2x8GB in the Snipers or Ripjaws X would be my pick

The values with OC means that it can only run ram at that speed overclocked I believe. The values without OC are the ones that are supported by the Mobo

 

[Tradesman1]

The ones with the OC means it may take an OC of the CPU to run at full spec

I am currently using the AMD A10-5800K APU.
I am considering upgrading the APU to the AMD FX 8320.

its proven that the Highest speed and latency DDR3 compared to some of the lowest speed and cruddy latency still only yield less than a 2 FPS difference in games. Dont spend too much money on ram for stats that look good on paper.

You obviously haven't used an APU with the onboard iGPU they love fast DRAM and will show a ton more than 2 FPS, also even with most non DRAM utilized games you'll still see more than that going form 1600 to 2400

I was using proven benchmarks from an i7 4770k OC and a GTX 980 oc

And here we are talking an APU, and possibly an AMD CPU which are not an Intel 4770K and a 980. But as far as a 4770K (I have two rigs running them, and a 980 (in one 2 of them) and a 290X in the other) jumping from 1600 to 2400 in most games yields more than a 2 FPS games, old games and those not optimized for DRAM at all will show little gain others can show 10 % or more and jumping even higher 'can' provide even greater gains depending on the games

I highly doubt jumping from 8GB 1333 to 8gb of 2100 Mhz ddr3 only can provide 10% or more fps. With a dedicated GPU at least holy hell.

Tradesman1 and aquaprofile,
Thanks for all your helpful information.
I am using a single Nvidia GTX 650 TI as my graphics card.
I started building computers when I first upgraded our old computer from a 286 to a 386. It amazes me (on a daily basis) how much I still do not know...
I remember the days of trying to figure-out how to juggle the interrupt cycles on the sound and modem cards so that the computer wouldn't freeze-up after it began the boot-up procedure. ("Why, when I was a kid we didn't have Windows - we had DOS! You couldn't just plug something into the motherboard and expect it to work, there was no plug and play, you actually had to know something... Ah, those were the days.") ha ha ha 😀

Remember it well, my kids started building with 486 rigs (they were little guys then 7 and 5), I started in systems back in 1980 w/ mainframes and went to minis and then PCs. Back in the mainframes at times we had to write our own drivers for some components, so it's much easier now

If you're running a dedicated GPU then honestly 1866 cl9 is going to get you the best price/performance ratio with the least effort.

Anything above is going to require you to manually enter all latencies & voltage manually in bios & will barely make a difference on the CPU compute side of things.
