AMD A10-6800K Richland Ram Speed Test - ADATA RAM - 2400 MHz vs 1600 MHz

We decided to test out the AMD A10-6800K at the stock speed with some fast ADATA ram. Here is what we used to test:

Here are the results shown in the video. We did some further testing at 2400 MHz. 

The system isn't the most balanced system ever. We just threw it together to specifically test the memory.

Nice test.

please do one with the system overclocked, ram 2400 or better, igpu 1100 or better and cpu 4500 or better. k thnx bye.

I think that's in store, this is just proof of concept with stock clocks on the APU.

Ahhh, logan got his hands on the 6800k, very interesting.

Interesting, I can't wait to see the video about CPU bottlenecking.

lol... i know what your results will show, on intel the difference between ram thats faster than native mmu supported will be small. on amd you will get consistently more bandwith and on amd apu's you will get a perfomance bump for using faster ram...

as for testing against the old i7 920 is that a dig? lol.(my  sys is i7920 based).. 

all you will see is more bandwidth on the ram but pertty much zero perfomance gains in real world aplication.

yes you will see a slight variance in that lower latency ram benefits games a bit more, while higher latencies but faster ram gives a little bump in productivity. but the difference is marginal at best your looking at 1-2% even with a 25% increase in actual ram bandwidth...

because the apu is a completley different design in that its much more intergrated the ram can have a much more dramatic effect on perfomance. the cpu mmu will still probably max out its ram usage at 1866 while the gpu part of the chip will take full advantage of the faster ram...

so while your conducting your test. please make sure you include cpu memory intensive tests not just gpu memory intensive tests.

 the 1 thing im unsure about is the amd apu mmu, when the cpu is oc'd does the native speed at which the mmu works also increase. if this is the case then overlocking that cpu could potentially bring a lot of perfomance gains i would like to see this tested.

 

beleive it or not im actually looking forward to the results. they will likely back up what ive already said and if they dont il learn something new... ;)

Added some more tests.

My friend is ordering this same APU and a few other different components today. I told him about the RAM speeds. He wasn't quiet sure it made that much of a difference.

Glad this came out now.

Sometimes, things amaze me, like the mega website actually uses the native open source standard strong encryption to push a javascript, that then uses it's own weaker nondescript 128-bit javascript based decryption... why? what's the reason? I hate stuff like that, because it's so contrary to logic that there has to be something wrong with it. Since there was no way to get around that javascript, and because Firefox didn't even want to play ball with anywhere near acceptable permissions, I had to install chromium and step run it in a container to get to the file. Totally space!

Aida also mentions a Samsung SSD, probably a false readout?

By the way, Gigabyte AMD boards also read out XMP profiles, and can overclock the RAM automatically to those profiles, and I'm convinced they actually implemented it before Asus. I'm not sure about MSI boards, but it's certainly not only Asus that offers that functionality.

Big thanks for the benchmarking, I didn't expect such good results from that hardware, it really opens up some economically interesting perspectives for allround systems, did you by any chance also test it in some manner with GNU/Linux with the latest open source v. catalyst drivers?

well heres an info i found out from the major brands of FM2 motherboards

correct me if i am wrong but so far I seen Asus is the only board which support up to 2GB to be used for Video RAM. And Asus BIOS combined with AMD Overdrive should allow the RAM and GPU to be overclocked at the same time. Reports the onboard GPU is able to clock at around 1GHz while retaining the stock CPU clocks and the faster GPU clocks does affect the games framerate.

Metro Last Night does make the APU system work really hard,

will you guys do more test using Crysis 3, BattleField 3, Far Cry 3 and Dirt 3? Since these games are the mainstream titles most are playing at the momentThanks

If you need a test bed for the i7 920 I can provide results also.

It will really be awesome when when we switch to DDR 4 and pair it with a 8-core APU

How about a video on overclocking RAM on AM3+ motherboards? Especially overclocking 4 sticks.

I don't know, but that would make more sense than buying >$300 RAM that was listed for this build. If I'm buying an APU based system, I wouldn't be spending that kind of $ on the RAM. I would be more apt to buy $60-80 1866-2400 based RAM sets (8 gb's) to go with the APU setup and thus make it a bit more affordable. It might just be me, but that is how I see it.

I do appreciate all of the hard work in testing this kind of system out, so we can see the benefits of the faster RAM, but for the $ it doesn't make sense to me.

16GB is quite excessive even for games which only use up to 4GB max

they were only testing to confirm that faster RAM means better performance on an APU system

should really try testing using AMD's new 13.8 beta drivers

you could choose cheaper RAM which are rated at 2400MHz and still get similar framerate

posted 8 months 2 weeks ago

They said this build was just to test the ram not an example to build a console replacer. Made such a long post for nothing.

These APU's make some awesome little 720p gaming rigs. Just grab some quick RAM and a 720p native monitor, maybe even a 1600x900 native monitor and the image will look fine. My brothers want a PC to play Minecraft, COD, and shit like that on so this is gonna work out great. I already have an A8-3870k that AMD sent me but I may just go ahead and get an A10.

XMP profiles always worked on my Gigabyte 990fxa-ud3. I don't see the point anyway, takes just as long to chose the profile as it does to chose the ram multiplier. Plus a couple seconds to set the latency. I guess if you don't know your timings the profiles could come in handy...

posted 8 months 2 weeks ago

So, does this seem to work the same way with the Intel chips? I vaguely recall it being said that it doesn't on a recent tech, but I may have heard wrong.

posted 8 months 2 weeks ago

Even if you go with a true budget build (not 1k like lunyone pointed out), with as cheap as gfx cards are getting, there's really no reason to get an APU system.  You can pick up a 7770 for $100, some even less with MIR's.  The slow ram vs fast ram argument is kinda invalid.  After checking prices on Newegg the cheapest (happens to be 1600) 8GB is $57, cheapest 2400 is $70.  Or you can buy 4GB of ram for $35 and put the left over for the 7770.  Cheapest on Newegg right now is $80 after MIR, only $45 more than the APU setup.  And some of that difference could prolly be made up with a different cpu/mobo choice.

 

You guys (Logan or whoever does the testing) should throw a 7770 on this system and put the cheapest 4GB of ram you can find and compare performance...

I have a misunderstanding or a question about memory RAM Logan is using. I'm not that new in computers but this is something is not clear for me. What is the difference between using a Corsair Vengeance that says 2x4 1600Mhz http://mae.cr/oYbP and a 2x41866Mhz http://mae.cr/j7iB ? I can overclock the 1600Mhz memory up to 1866 with my motherboard BIOS so, what is the difference?

posted 8 months 2 weeks ago

1866 memory is will run at 1866.  1600 may or may not be able to OC to 1866.  RAM is a bit different than cpu's and gpu's, they generally don't have much OC headroom than what they're rated at.  Just look this video, the ram is rated at 2600 but they weren't even able to get it to run that stable.... so maybe my first comment about 1866 running at 1866 isn't exactly true either, although it typically is at lower speeds

Could I get as much ajustability on the ram using this mobo: http://www.newegg.com/Product/Product.aspx?Item=N82E16813157339?

posted 8 months 2 weeks ago

and can you do a test of a 6800k crossfired with a 7750?

posted 8 months 6 days ago

I guess this is good to know if you want to know how to push your laptop to the max if it contains an APU. Other than that, if I would go for a stationary computer then I would go for a real graphics card and processor over an APU setup. But this gives me a sight of what a rig like that might be capable of doing. Thanks!

Looked all over before asking this.. What application do you use to test the speed at which the RAM moves data??

posted 4 months 3 weeks ago

Ok I got it.. AIDA64.

posted 4 months 3 weeks ago

What did you do to run the 2400 MHz memory on the mobo?

posted 4 months 2 weeks ago

Given the release of 2800mhz ram kits I would love to see a test with that, i realize its a tad on the crazy expensive side but it would be nice to see if it still scales well with the extra mhz or if it plateaus at some point
