Is 3000mhz pointless?

somsakjame · Nov 4, 2017

Hello everyone, thank you for answery question. I already order all parts for my new rig except ram.

Is 3000mhz pointless for ryzen 5 1600 OC to 4ghz? or should I get 2400mhz for $80 cheaper.

G.Skill trident rgb 16gb 3000mhz $309 Australian dollar

2400mhz is on sale for $230

Thanks guy

You will not see all THAT much difference in performance between 2400mhz and 3000mhz.

As you can see here there is only a 5fps performance increase between 2400mhz and 3333mhz in Ashes.

4fps in Rise of the tomb raider.

6fps in Thief. Etc., etc. Not enough to warrant paying an extra 80 bucks if gaming is where you are looking to see the performance at.

Personally, from the reviews I've actually looked at, I don't see where all these suggestions of great gains using faster RAM with Ryzen are coming from because the gains I see seem to be fairly meager as far as I'm concerned.

Put the extra 80 bucks somewhere else if you need to. It won't hurt to go with faster RAM that's for sure, but you're not going to see a giant return on your investment.

For editing and rendering will 3000mhz going to benefit me or should I stick with 2400 for $80buck cheaper

Even in the productivity benchmarks shown in the Anandtech review, I didn't see enough to convince me. I'd save the money or simply put it towards something else so long as the slower memory you are looking at is still Trident-Z memory.

And actually, from what I'm looking at there is only a 14 dollar difference between 16GB of Trident-Z 2400mhz and Trident-Z 3000mhz, so you might just as well go with the faster memory if that's all the price difference there is.

The reason many people suggest getting the fastest RAM you can afford and the motherboard supports is because the speed of the Infinity Fabric inside Ryzen scales with RAM speed. The Infinity Fabric connects the cores in the processor so it alleviates some of the latency between them.

Darkbreeze · Nov 4, 2017

Yes, but the Anandtech review of the gains based on infinity fabric using different memory speeds did not show me any significant differences. Until it does, my stance on memory speed will be the same as it has always been. Buy the memory that offers the best combination of speed vs price, OR, buy the highest quality modules you can afford and overclock them, or don't overclock them. Probably doesn't make that much difference either way so long as you're not running bottom of the barrel chips and entry level speeds.

Martell1977 · Nov 4, 2017

I do agree that $80 to go from 2400 to 3000 is excessively steep for the performance difference. Now if that difference was for considerably faster RAM, like 3600 or more, it might be tempting.

I've said this from the very beginning , past 2666mhz there's is virtually no difference to 3200 , maybe 2-3% fps at max in a few scattered scenarios.

Seems to be a mass snobbery thing when it comes to ram speed & people just keep repeating what they've heard elsewhere.

At $80 difference stick with the 2400 honestly, I'd that trident 3000 is cas16 then it'll probably only run at 2666 anyway.

I was lucky , bought crucial ballistix lp 2400 for an Intel build initially & it runs overclocked to 2933 with ryzen no-issue at all , I since settled on 2633 because performance is the same but without the voltage hike

I don't know Matt. I've had pretty good luck with G.Skill Trident modules on virtually every platform from the last few generations of both Intel and AMD, except for the Intel E and X platforms (Which I haven't tried because I haven't owned or worked on any of them.) , and the Trident modules have always been able to run at or above their labeled speed by either running the XMP or AMP profile, or configuring it manually.

The IC's on those modules are simply terrific and are well worth the premium over the Ripjaws or other memory products.
