1866 vs 1600MHZ DDR3 memory for an APU (3870k) @ 1080p

2013-11-01
welcome back to tokyo city's Barone's coming back to you guys today with a memory speed comparison for AP use testing 1866 speed memory versus 1600 speed memory and motive li testing whether this makes a difference for FPS now I'm testing at 1080p and I'm also testing under 3/8 70 K which isn't as fast as the 5800 of the 6800 k but it's still a decent APU now I'll be giving showing you guys the benchmarks and also be showing you guys a recommended bios tweak at the end and also give you guys my thoughts and opinions on what I think you know but in regards to this APU and memory speeds so anyway let's get on with the benchmarks alright so looking at the first benchmark here we have Batman Arkham Asylum this is at 1080p and medium quality settings and we can see here that there's virtually no difference the only difference was in the average frames per second which was like point to 2 frames per second higher which is pretty much put that down to variance the minimum and the maximum were the same now looking at black ops 2 at medium quality settings at 1080p again we had almost virtually the same results with the maximum banks just one frame higher at 1866 and the average being slightly lower at 1866 but again you can put this down to variance so virtually the same with black ops 2 now skyrim this is 1080p ultra now this is a setting that I know is stressful for CPUs and RAM because when I did these tests on my Intel it did net results between different Ram speeds and again that does net different results at 1080p on Ultra for an APU so at 1866 the maximum is were the same but the minimum was one FPS higher 14 dresses 13 and the average frames per second was 17 point one two verses sixteen point five two now although that's not much of a difference in broad numbers in percentage terms it's I think roughly I don't know maybe you're almost five percent I'd have to do the calculations but again it made it a bit of a difference but ultimately the biggest difference that was was made in terms of AP use performance for AP use was changing the amount of dedicated ram in the BIOS so the auto it's scary to note that the auto setting for this is 200 fifty-six megabytes on the three at 70 K the 5800 K in the 6800 K I think it's 512 but you want to at least max this out so I'll show you those this tweak right now and basically when this was on auto at 256 megabytes of dedicated DDR Ram for the air for the GPU portion of the APU we saw a fourteen point fourteen point four four frames per second in Skyrim with a minimum of seven and this was really horrible screen tearing this was unplayable like completely unplayable the maximum was also low as well when we changed this to 512 which I did on my tests on 512 dedicated megabytes of RAM we had here the average as you saw in the benchmark before sixteen point five two so that was a pretty quite a big difference quite a significant difference so let's move on now I'll show you guys how to do this involves how to change the dedicated memory for the APU in the bus so I want you to guys to start up your computer and enter BIOS bar there hitting the f2 or the Delete key and now once you're in BIOS will notice straight away that it just as it says here 256 megabytes of shared memory that is the auto setting now we're going to want to change this and also one important thing to note is that different motherboard manufacturers will have different looking biases so this is the asrock UEFI bias for the fn1 motherboard so once we've done that I want you guys to go over to the Advanced tab and into North Bridge configuration now once we so hit enter and once you enter here you can go down to share memory and you can see here it's on order I want you guys to change this to either 512 megabytes or higher if you can and basically what this will do would give you it'll give you the best performance increase as opposed to memory speeds per se so after you've done that just hit Save Changes and exit and you're good to go so in conclusion I will say that I do not recommend spending money on faster memory for an APU in order to get an FPS increase I would honestly just save that money and put that money into a dedicated graphics card and I'm gonna be releasing a video pretty soon that shows the difference between APU and a dedicated gaming rig like my own rig so I'll be doing some benchmarks apples to apples however keep in mind that you know my rig is overclocked and you know the APU rig is not overclocked but it just goes to show this the next the next video that I will bring out will go to show that you know apos really aren't as they're nowhere near as good as a dedicated CPU and a dedicated graphics card so you know if you guys want to go with an APU pacifically for gaming then I only suggest doing so if you can't if you can't spend the extra money like if you can only go with like a 300 dollar budget because if you can get like a 400 dollar budget you can get something like a 77070 and that will kick the pants off any APU out there at the moment for gaming so guys I hope you enjoyed this video if you did please give it a thumbs up and if you have any questions about this video please leave a comment the comment section below and I'll get back to you guys as soon as I can anyway I hope you enjoyed this video and peace out for now marine easy bite
