hey what is up all you techno fans and by techno I do mean technology take up use that joke before that's okay because there's nothing redundant on YouTube everything is absolutely original in the past I've done a couple videos about how to overclock your graphics card or how to overclock your cpu both Intel and AMD and all that good stuff but recently people have been asking me well what effect does vram have on your overclock does increasing your VRAM actually give you better performance does it give you better frames per second does it cook you breakfast in the morning well that actually depends what's an AMD or an nvidia card but I digress so we're going to talk about today is the correlation of VRAM and how it affects your performance and obviously we're going to be using my envy surround set up behind me with my 780 s in sli 2-way SLI now the configuration behind me is running in 57 60 by 1080p so what that's going to allow us to do is not only check how vram effects you know the overall performance and frames per second of those monitors but it's also going to allow us to see how close we're getting to the vram cap because the two things that you constantly hear about with vram is one you have to have a whole bunch of it if you're gonna run a high resolution and two that you need to have super fast vram when you're doing ultimate gaming or a high resolution gaming now I'm really going to only be using two benchmarks for this particular test and that's going to be both valley benchmark because it's going to give us a hard number that we can see both minimum maximum and average frames per second over a synthetic benchmark and then we're going to hop in some battlefield 4 and we're going to look at average frame rates in there with different settings on the vram speed and with you guys i'm going to find out what the actual results are believe it or not I've done lots of overclocked benchmarking when it comes to court but I've never actually done any standalone Ram tests to see exactly what the hard differences are so we're going to learn together and together it's just the way I like to do this weird anyways I bet okay guys we're back now and I have spent the last couple of hours going over these benchmarks again and again and again trying out different things making sure I get my baselines and trying to bring you guys the most accurate results that I could not bear in mind this is my setup specific to my graphics cards how they perform my surround setup and you know your results may vary I mean this is all based on my GPU my CPU my motherboard my cooling so your results may vary so keep in mind these are my results they're not the definitive you know all-inclusive for every situation in the world type of results now for the first test as I mentioned I did Valley benchmark which I find to be the most consistent way of measuring even small changes when it comes to your system games like behind me there's a lot of things that are always happening explosions at different times different things being rendered different parts of the map different player interactions explosions and jets and choppers and boats lots of different variables which can really make the outcome different every single time so it makes it very difficult to baseline so that's why we use valley benchmark to kind of do our side-by-side comparisons now for valley benchmark results this is for one monitor not surround just one monitor and I found that to be pretty much the most consistent way to measure the differences because again with surround there's going to be a lot of different changes there now when it comes to the valley benchmark results there's a lot of numbers here just kind of look at the chart and let that be a little bit more of a visual aid to the numbers I'm going to give you here now that no overclock whatsoever on the GPU or the RAM that's one thousand six megahertz on the GPU clock and the six thousand effective megahertz on the RAM three gigabytes of RAM we are getting a score of forty five sixty nine an average of 100 9.2 frames per second with a min max of forty one point seven in the maximum of one hundred ninety three now utilized RAM on that was one thousand three hundred sixteen megahertz or forty three point eight seven percent utilized Ram at one monitor now that's expected results because we are talking about one screen with three or one 1080p panel with the you know 3 gigabytes of RAM that's more than enough now when you overclock just the memory and you leave the core where it's at our score jumps up to a 47 11 that's a jump of about 140 points and minimum are an average of one hundred twelve point six frames per second that's a three frames per second average jump right there so that's just by overclocking the RAM 500 megahertz or one gigahertz effective so going from six gigs to seven gigs netted us only a couple of percent of an overclock or increase in performance there and that's about three frames per second 3.4 frames per second average increase by moving the slider on the RAM one extra gigahertz and that's utilized percentage of forty four point five six percent utilize of the three gates now when we overclock the GPU and we leave the memory at stock speeds we were getting a 51 51 score that's a couple hundred about 400 point jump 140 point jump and our average FPS jumped from 112 to 123 inside of valley benchmark so you can see obviously we got the most result by overclocking our GPU even by leaving the RAM stock now if we go ahead and overclock our VRAM our score jumped from a 51 51 to a fifty-four forty nine and an average FPS of 130 point two so that's adding another 7.1 frames per second by adding an additional RAM overclock to the GPU now what's happening there is your GPU is getting faster the RAM has to get faster to keep up with it so that's why we're seeing kind of these linear increases in performance by moving those sliders now let's go and utilize RAM again 1315 megabytes at forty three point eight two percent utilize that's pretty much baseline because the synthetic benchmarks not really changing and we're only using one panel okay now let's go ahead and take these exact same scores and bring them over to battlefield 4 now the first thing I want to go ahead and address is at 57 60 by 1080p at ultra preset which is you know MSAA and everything on the max we were utilizing all three gigabytes of our VRAM now I want to point something out here before we move forward now this is the part that I don't really find surprising I guess I'm a little bit surprised that we did utilize all three gigahertz or three MiG's of RAM I didn't think it would cap out but I think what's happening here is the utilization of RAM in these graphics cards has progressed to the point to where they're very dynamic and the game will use as much RAM as available to it if it feels that it needs it but you're not going to start experiencing crashing or blue screens or anything like that by capping out your rim because the entire time I played I was capped out at three thousand four megabytes utilized Ram in battlefield 4 on both GPUs just straight across the board completely capped but I wasn't getting stutters I wasn't getting slowdowns I was getting very smooth frame rates now if I brought that down to one screen I was getting about nineteen hundred and fifty megabytes used of RAM now here's the part where I think it's a little bit surprising is utilizing battlefields for with my old 680 which was a two gigabyte card I was easily utilizing about 1400 megabytes of that ramp so by going to a faster and more robust GPU like the 780 the game recognized hey we've got more potential here so we're going to utilize more of the hardware so that's the part that I found kind of surprising the programming in these games is a lot more dynamic where it recognizes what you have and then goes ahead and increases the utilized hardware to give you better performance overall so that's the part I didn't expect but I can tell you right now running three screens with three gigabyte cards they did cap out the RAM but I did not have any adverse effects those rumors of cattle if you utilize all the RAM you're gonna you're going to add blue screen and you're going to get kicked out of the game you're going to get huge spikes and stutters didn't get any of that guys so it just means that the memory controllers of these GPUs are a lot more intelligent that a lot of people give them credit for okay enough about that let's go ahead and talk about the frames per second increase when it comes to battlefield 4 at base settings with the sli enabled we were getting an average of 80 frames per second in ultra preset when we went ahead and bump that up to stocke GPU speed and 1 gigahertz overclock on the RAM we did gain 3 frames per second average for an 83 bumping up the overclock on the GPU to 13 hundred and 50 megahertz and leaving the RAM stock at 6 gigahertz we got a 92 frames per second average in SLI and 3 screens and then going ahead and overclocking both to the max 1350 megahertz 7 gigahertz on the RAM we got 95 frames per second average when it came to both graphics cards and three screens so there you go guys these are my results basically the more vram the better but if you don't have quite enough as you can see the game will go ahead and the graphics cards rather will self manage the memory and they'll just make best use of what they have available to them without kicking out of the game or crashing or anything like that so there you go you can see very modest increases by overclocking your V RAM but obviously the grunt of all of your performance gains is going to come from the overclock ability or the luck of the GPU lottery that you get when it comes to overclocking your graphics cards so what do you got your guys's results what kind of performance have you seen by moving those sliders on your graphics card AMD Nvidia sound off down then just in the comments down there and let people know what kind of performance gains you're getting by tweaking and having some fun with those graphics cards guys I'm going on out of here maybe enjoy some games and as always follow me on Twitter if you guys want to talk about today's video take it over to the website Jay's two cents calm and I will see you in my next video
