An Independent Study: Does The Speed Of RAM Directly Affect FPS During High CPU Overhead Scenarios? - Page 22

post #211 of 277
I worked on an article for TheOverclocker where we looked at the effects of memory speed on a Core i3-6300, some of the biggest gains came from upping the RAM speed to DDR4-3600 and not from increasing the CPU speed. You can read it here https://www.joomag.com/magazine/mag/0458172001466490420/p14

I am actually working towards stabilizing my 32gb (2x16) 3200 CL14 kit at 3600mhz as we speak wink.gif. Proves not to be as straight forward as I would hope for. I remember now why I am not a fan of ocing RAM

what mb?
many of the cheaper z170 mb use a thinner pcb so they dont support over 8g sticks at 3000mhz and only 4g sticks at 3200-3400
while the likes of asus hero support 16g sticks up to ~3400
it may still be possible to get it stable with higher levels of vtt

yes i believe they used average fps
arma min fps can be very random they would have to run the test many times to get a clear picture

i can understand why you want to see min fps though as when i tested dragonage ht helped max fps the most while ram was a bigger help to min fps

Pretty interesting results. Thanks for keeping it updated with newest games!

I've 4 sticks of 4 GB 1600 MHz RAM with CAS 11, coupled with a FX-8320 @ 4.5 GHz, running on an ASUS M5A97 R2.0, which supports up to 1866 MHz RAM. Do you think I'll get a meaningful boost to my framerate (particularly in GTA V, which sometimes drops to higher 30s, for some reason) if I upgrade the RAM to higher speeds? I really want to improve the min fps and frame time as it can be quite distracting.

Also, do you think OC the RAM will give me decent results? I tried to once, but the PC failed to boot. My main concern is the mobo, it's just a midranger, and I fear I'm taking all out of it by running the CPU on 4.5 GHz. FYI, my PSU is of no concern, it's decently overpowered at 850 W and it's a Tier 2 one so it's high quality.

VIII Hero Alpha. I think it must support 32gb in 2x16 config as it has built in OC profile for 2x16gb Samsung modules 3600mhz actually. Not that it is a good profile but it is there.

How far would you push DDR4 voltage for a daily use?

First, try overclocking the memory controller. Then, do some testing.

Next, underclock the ram and/or increase ram timings. Then, do more testing.
If performance decreases significantly (after underclocking ram), it means there could be a benefit to using faster ram and/or overclocking ram.
If performance does not change (after underclocking ram), then it means you don't need faster ram.
Tell us your test results, please.

What do you guys think of this video?
I find it very confusing that he's comparing 2 different things against each other in one go : more and faster RAM, against less and slower RAM.
Luckily in the same box, only the RAM is different.

Also I can't help but think that the video was deliberately recorded to promote the larger (capacity) and faster RAM sticks.

Yes he should've just did it "live" that will eliminate all of the other stuff causing more ram usage. I still stand by that 16GB should be the bare minimum in this day and age.

I do know one thing is that I tested Battlefield Hardline after overclocking my memory from 1333 mhz to 1866 mhz and it jumped around 10 fps overall. I was shocked. I have overclocked another batch to 2400 or a bit less with slower timing and it still pulled a good chunk ahead of faster timing slower mhz setting.
