Hey there,

I'm noticing more and more, that when it comes to RAM speeds, people are still spending HUNDREDS and HUNDREDS of dollars per build for a board that supports the latest frequency of ram, sometimes an extra 100 for a DDR x board if the new ram stepping is out..
Can i ask... why? Why do people still seem to class RAM in their System build as JUST as important to have the newest and fastest and most overclockable like it's just as big of a benchmark as the CPU's ability to boost, keep cool and overclock? Or the graphics card? I mean, they've gone as fat as COVERING the little things with massive heatsinks and even fans on them, sometimes spending like 500 dollars on the laest 128gb set of DDR4 10k overclocked to it's maximum stable of 10240MHz etc...

Again, why? I've been following the speeds, ram timings, ram types on and off for years, and i think everyone has been had!

Again to reiterate, people seem to be upgrading their ram, and overclocking it and treating it like it's just as important to keep this stuff up to date and overclocked just as much as the CPU and GPU, which is absolute nonsense.

The biggest difference to usage and gaming, was the dump from SDR to DDR. Double data rate. That's it.
Like DDR literally doubled the throughput of data between itself and the CPU.
And because of this, alot of people naturally think that DDR2 triples the rate, and DDR3 Quadruples it etc, when this simply isn't the case.

I was doing alot of testing back when the switch went from DDR2 to DDR3. I tested a couple of games on my 4gb DDR2 @800Mhz vs my new DDR3 @ 1600 MHz, so naturally you'd think "Well this is gonna give me double the data rate". But it didn't. It barely made any difference at all. Like in some cases i was getting a couple of more frames per second from the DDR3, but then in the same benchmark in the same game, i was getting more FPS on the DDR2!

And the same is happening again today. There's LITERALLY no difference to the end user in speeds or noticible FPS between DDR3 at 1600Mhz, and DDR4 at 4800Mhz overclocked within an inch of it's life.
you MIGHT see a 2-3% difference in SOME small parts of benchmarks, but to the player, himself, playing the game, rendering the model or scene etc, it's ABSOLUTELY 100% and categorically identical.

There's no difference in real world applications between DDR3 1600Mhz and DDR4 4800MHz overclocked, and there CERTAINLY isn't any difference whatsoever between Ram running on the same stepping with just different timings. (like 2 lots of the same DDR 4 and 1 is running at an overclocked rate). All you're doing is putting stress on your components, costing yourself more money in electricity etc, and wasting hundreds of dollars per year, and thousands over your whole career as a system builder.

I know it sounds like i'm shouting lol, i'm not, i love overclocking and stuff, i started off back in the early 2000's when i had an AMD Athlon Thunderbird AXIA 1.3Ghz which i had overclocked on air at 1.71GHz (that was massive back then) and 256MB of SDRam, and a Geforce 2 GTS overclocked on the memory and core up to Grforce Ultra type speeds.

We're being ripped off with the ram.
The fact that everyone has switched to a new motherboard, new CPU's etc in alot of cases to accomodate this magical DDR4 4800MHz that can be overclocked like this is gonna give them some extra magic boost in their gaming etc, is just nonsense.

Has anyone else been following any of this? Like there's barely any tests ANYWHERE of someone testing the real world speeds od DDR vs DDR 2 vs DDR 3 vs DDR 4 and CERTAINLY none doing all types at all common and overclocked speeds and putting all the data out. All we're seeing is like Sisoft or whatever telling us what should happen theoretically, when in reality, there's is hardly any difference between the generations and I'd say NO difference between ram timings in ns or frequency,

if anyone would like to add onto this, or to correct me I'd be delighted to chat.
Thanks!

I read a website talking about RAM speed and it showed that there was no real difference between faster and slower RAM. That's why I chose 1666 MHZ I believe it is. Bad enough each 4GB stick cost me about $50 bucks. I only have 8GB right now. But I suppose as time goes on I'll upgrade to 16 GB eventually.

sigh... your methodology is all outdated.
Back when we overclocked, the era's you talk about, ram speed mattered because cpu clock speed was linked with ram speed. This was because we had a locked ram divider, and we also had locked multipliers unless you went (Extreme Edition / Black Edition / I ram Rich beyond *Beep* edition) which had unlocked multi's.

So until intel gloriously released the ram ratio divider, the higher clock speed you went, the faster the ram you needed, and the higher core clock you could net achieve....

However now with unlocked multipliers, we dont need to fiddle with fsb/qpi/xxx gen tech, and just mess with the multiplier.

But now cpu's are way more sensitive with ram they used to be.
Which is why im saying again, your metholody is grossly outdated.

These 2 videos on modern processors clearly show the impact of ram speed.

This video clearly shows advantages in ram speed for gaming on Ryzen even.

This is KrabyLake, and you see a difference.

CoffeeLake is suposed to be more sensitive to ram then KrabyLake + Ryzen, so no.

Both cases show almost a 10FPS difference from the slowest -> highest tier.
10FPS is almost on par with a VideoCard upgrade to next tier... like going 1070->1080

Ram speed plays a lot of difference, it always has, but even more so on the newer gen processors.
Ram timings also play a big role, but only when the offset of ram speed is small, otherwise ram speed will be better prefered over ram timings unless your worried about ram compatability.

Ram timings > ram speed when your looking at compatibility, because there are more boards willing to take 2400mhz ram then there are 3600mhz ram.

Ram Speed:
It used to matter. (Pentium 4 / Athlon - PC @66-133MHz)
Then it stopped mattering so much. (Core 2 / Phenom - DDR2/3 @400-1333MHz)
Then it started mattering again. (Ryzen CPU interconnects running at RAM speed.)

It's always mattered a lot for IGP applications, as well.

RAM speed definitely does make a difference. Maybe not as much as a better CPU, GPU, or SSD, but to say it doesn't matter at all is incorrect.

I don't have the time to find the links, but in things other than games, at least for Ryzen, the performance difference can be far greater than that video. For some applications, its almost linear, the speed increase with the memory speed increase.

Do you think it's worth upgrading your ram and board for hundres of dollars per stepping change for those frames just on Ryzen? the same isn't so for Intel. you're barely notcing any difference at all on core i CPU's. literally maybe 1 or 2 between 2 generations of Ram

You don't have to upgrade your board for Ryzen for faster memory. Every board I have seen will do 3200 speed., and again, gaming gets you a small increase but other apps get much more speed increase. If you can't bother to READ some of the threads and research it yourself, continuing with this rant is trolling.

wait why you bringing in motherboard and cpu to this discussion?
Now your telling me a platform swap?
Is it worth someone to upgrade to ryzen... possibly depending on what the system is used for and what they are currently on.

If your still using that old athlon xp processor on socket 462... then hells yeah, its worth the upgrade.
My Samsung Note 8 Phablet is faster then that old antique you call a PC.

where are you getting 100's of dollars being the price difference?

DDR4 2400mhz Corsair LXP ~ $179.99
https://www.amazon.com/Corsair-Veng...AIR+VENGEANCE+LPX+BLACK+DDR4+2400MHz+16GB+KIT

DDR4 3200mhz Corsair LXP ~ $219.99
https://www.amazon.com/Corsair-Veng...AIR+VENGEANCE+LPX+BLACK+DDR4+3200MHz+16GB+KIT

Price difference... $40.00

40 dollars is a lot less then hundreds of dollars, unless my math fails me.

Maybe but as you yourself showed before you get maybe 10FPS tops difference in canned benchmarks,in one or two of them only, wich means there will be no difference in actual gameplay since canned benches are overly sensitive to crap that doesn't make any difference in real life or they completely miss to measure things that have a huge impact on gameplay like in the videos you posted where you only see flybys with scripted and predetermined everything,so even if it's only $40 it's $40 too much.

The strategy of many gamers has been to build a platform that will last for years, and require nothing beyond a vid card upgrade later. A good number of members here are still rocking gen 2-4 Intel or AMD FX based systems. Budgeting for high performance or excellent overclocking memory makes sense, as it will be anchoring the system for years to come.

I suggested back when ram was cheap, that everyone asking how much to put in their new build, move to 16GB as the standard, and there were some arguing against it. "You don't need it. 8GB is fine for your new build." Some of us that have been around long enough even intimated that cheap ram was not a norm, and there was no reason not to buy more. The gamers that took the advice to just buy 8GB done goofed.

And before someone chimes in with how 8 is still good; it is mostly still servicable, but 16 is better. Some games already make use of the extra memory, and various tasks can benefit from the high performance kits.

If you are on a tight budget, it is definitely one of the places you can trim the cost down. But otherwise, pony up for better stuff, and thank yourself later.

RAM:

Capacity > Speed > Timings, importance in that order.

As several have already pointed out in the thread, memory performance does matter. Especially when using an IGP, and on Ryzen platforms. Does it matter enough to be worth the additional cost? That an individual concern.

Canned benchmarks are more likely to have well behaved cache-friendly sequences, so memory will have less impact. Real gameplay is more unpredictable, meaning it is more likely that you will access a chunk of memory that has not been cached in L3- at which point your memory bandwidth and latency matter, a lot.

U no have so lot cache...
It's all about how many bytes you can push around ,which is only realistic in scenes like this one where pretty much nothing is going on.

1). RAM is expensive due to low supply and high demand. You will pay out the nose even for basic DDR4-2133
2). All modern platforms want fast RAM - especially the dual-channel setups. Testing backs that up. This applies for Skylake on up on the Intel side, and Ryzen on the AMD side.

If you don't want your system to be at its best, fine, go buy DDR4-2133. Plus there is no DDR4-4800 so stop pulling numbers out of thin air.

Otherwise your rant makes very little sense. Neither you nor anyone else has benchmarked a platform running DDR3-1600 and DDR4-4800 on the same board/CPU, for reasons which should be fairly obvious. So again, go get whatever's cheap and be happy with it if that floats your boat. I paid $160 for DDR4-3733 in Nov. 2016, and today the same kit costs over $200. Now you get DDR4-2133 for the same amount of money. What a bargain!

To me it makes sense to put some thought and money into buying decent RAM because it is one of the few components where it may make sense to move it with you from build to build across several generations of hardware. That said I think, like with most things in the PC world, there is a very clear price/performance tipping point where it no longer makes sense to pay ridiculous premiums just for numbers.

Also, not to be that guy, but G.Skill has technically shown off DDR4-4800, but it's not for sale yet as far as I'm aware.

May have made sense at some point but seriously, now you get a CPU and you can stick with it for 4-5 years easily wich means that the new type of DDR will already be released.
Does it make sense today to build a DDR 3 system because you have the ram left over?

Given the high costs of DDR4, it may indeed. I just built myself an FX 8-core rig with a Gigabyte 760G R2 board, and 16GB of DDR3. Just for fun.

I personally prefer to stay within official specs when running expensive hardware or even not so expensive hardware. As I may not be able to replace it if it dies early.
My 1950x and x399 Taichi officially supports DDR4 3600, and thats what I run.

So what is your point ?
