DDR2 Bottleneck

[kuraiskrap]

So i remember hearing/being told Ram wasnt really a bottleneck

however i saw this Video the other day

right now im running a Q9400, overclocked to 3.6ghz (450FSB). my rams running at 900mhz with 8gb, i was considering upgrading to 1066mhz ram so i could overclock higher safely (ifi could get it on the cheap). i was wondering if my ram would be a big bottleneck. im running it with a gtx 970 (i know my GPU is bottlenecked to hell, my FX pc crapped out so i scrapped together a beautiful 775 rig from various sources while i wait for Zen)

im basicly hopping to max out the performance out of this,as a hobby, and for performance

Ahh salazar studio, cool guy. Anyways memory has changed now. Kind of depends I guess idk I just know have t least 1333mhz memory and good memory. Thats the guide I refer too.

Your runnign a slow cpu, ddr2 won't slow you down.

RAM most of the time isn't a bottleneck because most of the time the RAM you put into your system is specced for the CPU in question. In other words, the performance of the CPU is such that going any faster with RAM doesn't matter. For example, if your CPU is crunching at a video and it can only spit out say 100MB/sec of data, then theoretically even DDR-400 should cover this and going faster won't help anything.

 

That video showcased what happens when you deliberately downclock RAM well below what the CPU is specced for. Though it could just be because the RAM was downclocked so low, the rest of the CPU stalled because it was waiting for the memory controller.

 

In other words, absolute RAM performance has nothing to do with it. As a some measure of proof, Anandtech tested the i7-6700K with DDR4-2133 and DDR3-1866, and aside from a few benchmarks, there was tiny performance change in both directions.

DDR4 at 2133 MHz bottlenecks compared to at 3000 MHz, ever mind DDR2. Whenever Linus opens his mouth these days it's pretty safe to assume he's talking BS.

Well, my CPU on CPU benchmark is 4873
it scores a 366 in cinebench (testing with a bunch of stuff already installed).
its old tech but the overclock pushes it performance wise into where DDR3 would be alot more commonplace.

In fact my Board has a DDR3 version. on CPU benchmark my CPU is basicly on par with   i7-6650U (which supports DDR4) or  Intel Xeon E5620 which also arent exactly "high end" but its when DDR3 would be expected. im also running Modern titles. which considering the ps3/xbox360 had very little ram, and the ps4/xb1 has plenty. i figure modern titles might rely on ram alot more then previously
