GTX 1080 HTPC - Project Fat Guy in a Little Case (Build sanity check) - Page 2

post #11 of 16
Build looks pretty solid, but you do realize by running only 2400MHz memory you are restricting the maximum amount of performance you can get out of the build in games. Has been proven that faster memory helps out in various gaming scenarios.

You can get 16GB of 3000MHz DDR4 G.Skill Ripjaws for $61.99:

Good find on the ram, same model just bumped up stats with the same CL for cheaper. thumb.gif

Interestingly, I came to a different conclusion after looking at bechmarks. (limited research)

Here are the links I looked at:
http://www.anandtech.com/show/8959/ddr4-haswell-e-scaling-review-2133-to-3200-with-gskill-corsair-adata-and-crucial/6
http://techbuyersguru.com/gaming-ddr4-memory-2133-vs-26663200mhz-8gb-vs-16gb?page=1

To me, it seemed that on a single card the frame rates vary by maybe a percent or two which is less than a frame in real world scenarios.
On an SLI or CFx solution, the performance seemed to have more variance and only in some games. This makes sense for memory intensive games that heavily utilize parallel computing, but the gains beyond 1% seemed inconsistent.

The difference between half a frame when comparing 2133 to 3000 seems nearly inconclusive. DDR4 speeds didn't seem any different than DDR2, or DDR3 as far as impacting games.

Then again this was just a quick conclusion, were there other tests run that showed more significant results? This seems more like max/min ing, when price is probably the more relevant factor. (Given you game me 3000 cheaper biggrin.gif)

Yeah there are a few other tests showing much better findings, there are many others but this test seems to be the most concise:

Seems though the sweet spot for DDR4 and gaming is 3000MHz and the best results are when you overclock your CPU alongside using faster memory.

Good info man, thanks! Bought all the parts. Went with an EVGA 1080 FTW. Wanted the Zotac AMP but wasn't fast enough. I'll start a new thread once I have all the parts. Thanks!

No problem, glad I could help. Don't worry about going with the 1080 FTW you will be happy you went with EVGA anyway because they have the best support.

that was my thinking. I've dealt with them enough, the small perf difference is justified by their support.
