    latency is the key of ssd improvements over hdd's

    throughput would only matter if you're entirely loading a universe into memory and keeping it there.

    I'm still annoyed I bought a 970 pro, honestly. people wen ton and on about how much better MLC is, so I mostly did it for that reason instead of speed claims. But most people would never touch the write limits on any ssd, anyway...

    And, in general, the better ssds are double the price per GB compared to the ones that are still very good.

    Just read where AMD themselves confirmed the new cpus will perform the same on x570, x470, and b450 if you don't need pcie 4.

    Like I said, the ONLY reason I was considering an x570 was where the extra bandwidth would allow me to use multiple ssds at 3.0x4 AND a gpu at x16.

    But since 1 ssd at 3.0x2 or a gpu at x8 will make little to no difference I may just save myself well over $100 by not getting an x570.

    I've just got to decide whether to keep the one I have now, which means I'd have to get a "loaner kit" from amd, or return it and buy a mobo again when these cpus release.... which likely won't be as good mobo prices at that time.

    wayyyyyy off topic, but if you have a file from a dual layer BR, which I believe those hold 40 or 50 GB, why don't you need that much RAM if opening the file on the pc?

    Someone told me at one point that when you open it, it doesn't put the whole file in memory as it plays the file, but I just read somewhere else that seems to be saying opening a video does put it all in memory. Obviously, if it does, more people would be needing 64GB RAM.

    Gaming wise about equal, total system performance ~30% higher on 3700X. With your GPU practically equal for gaming even if you had weaker CPU.
    If you are going to upgrade to shown Navi which competes with RTX-2070, then you have still about equal performance in games as GPU will be limiting factor in most cases.
    Do you have 144Hz screen? If you sit on 60Hz, then you do not really need CPU upgrade just yet for gaming. Within a year 4C/8T may show deficit more often, but now on 60Hz it is OK.

    As for economy part. Yes, AMD is still more economy oriented side.

    I don't see how Ryzen 3000 is going to make memory prices go crazy. I think 3866-4000 will be a bit high but I guess it depends on the timings we are talking. I doubt it will be the sweet spot. 3600 CAS 14 will probably be pretty ideal. It will be interesting to see how these new neo GSkill kits turn out.

    You'd be paying big time prices for it, compared with what most RAM costs now. That's if it even exists... On newegg they don't even have any 14 latency 3600 and filtering to 15 latency only gives 1 kit showing up. And that 15 latency 16gb kit costs more than a 32gb kit of the same speed and 2 or 3 times as much as another kit they have on sale with 18 latency.

    It's hard to get half way decent prices on 14 latency 3000 speed, let alone 3600 speed.

    Too bad all of their good deals are on 16gb kits, too, or I'd be tempted to buy a kit of 3600.

    I have 4x 8GB 3600MHz CL16. I bought it at time when memory prices were high. Its price is now mere 10% lower than back then.
    But cheap low-end memories now cost half of what they did at peak of prices. Sometimes even less and one can get for half price better low-end memory than before.
    2x 8GB 3600MHz CL16 costs 2.2 times as much as 2x 8GB 3200MHz CL16.

    If you want faster, memories have CL19 or worse. 2x 8GB 4266MHz CL19 costs 30% more than that 2x 8GB 3600MHz CL16. (And it is same model which I have and they have exactly same frequency/CL potential.)
    Then there is 2x 8GB 4600MHz CL19 (19-23-23-43) which is another 30% more expensive than 2x 8GB 4266MHz CL19.
    And those last 2 mentioned are quite more expensive than my 8GB 3600MHz CL16 sticks were at peak.

    So, if someone wants 2x 8GB 4600MHz CL19 (19-23-23-43 which is not great) over 2x 8GB 3200MHz CL16, it does cost 3.67 times more. At high end segment priced did not really go down in any significant way.
    + those kits with clock above 3600MHz require 1.4V or 1.5V. People who want good memory should stick either to 3200MHz CL14 or 3600MHz CL16. But later can run in former configuration if desired.
    = = = =
    Would I want to spend $150 more on very fast memory and get 8C/16T or would I want to spend $150 more on 12C/24T CPU while using just good enough memory?
    I would likely go for more cores and slower memory as I know that most of my heavy workloads can utilize all those cores even with much slower memories.

    But someone can really go for best priced 2x 8GB 3200MHz CL16 + 3700X and be happy as it will not hinder system performance in most of cases by more than 3~5%. And that's wort it. If better memory increased total system price by mere 5% and enabled CPU to deliver same performance bump, it would be good investment. But that's not the case. In cases like Cinebench (small kernel which is not memory intensive) one can get 2% higher performance by moving from 2833MHz CL16 to 3200MHz CL14 or 3466MHz CL16.

    Optical media uses an block/address file system with an index in the initial track so you don't have to read the entire content of a file to get to the part you want.

    Canada Computers briefly had the R9 3900X listed on the site yesterday, and now the listing is gone. It was 709.99 before tax. After tax in Canada, this CPU will cost 800 bucks. A few days ago I said this chip would end up costing Canadians 800 bucks after tax, and people claimed I was way off. Very disappointing for Canadians. This chip won't sell well at this price at all. Most people will just not pay it.

    But he said CL14 3600. I haven't even seen that any exists. If it does newegg's filtering doesn't even have it listed. CL16 3600 would be equal to about 3200 CL14 as far as latency, so would be understandable. CL14 3600 would be like CL12 34200, which doesn't exist in DDR4, at least.

    So any other opinions on what I should do about RAM? To recap, I have g.skill 32gb 3200 CL15. That's not a common combination of specs there, so I am unsure what I could even sell it for.

    Some think I should sell and buy something from QVL. Some think I should open and try it, but problem there is it would lose value by being opened.

    Mine is Samsung b die. So that's a plus. But g.skill only lists pretty ancient chipsets as compatible officially.

    I would "like" to probably get 3600 CL16 or CL17 or maybe even CL18 would be good enough? But they typically only have good prices on 16gb kits and then I'd probably lose a lot in selling my current one.

    Samsung B-Die DDR4 3200 will almost always work at DDR4 3333 speed with 15-15-15-15-35-2T or even 1T timings at 1.35V. You should also be able to run 3466 speed at 16-16-16-16-36-2T or 16-17-17-16-36-2T at 1.35 to 1.38V. Since you have 32 gigs of B-Die already, you should just keep your RAM. You have quality RAM, so not worth wasting the money to get a bit faster speed kit. If you had a lower speed kit, which was something like 2666, then sure, selling to dive into some 3600 would be a great option. I have DDR4 3466, which is also Samsung B-Die. I currently run the RAM at 3333 with 15-15-15-15-15-35-1T timings. A friend of mine owns a Samsung B-Die kit of 3200 on an X470 board. He also runs 3333 with 15-15-15-15-35-1T at 1.35V.

    Thanks. As far as those speeds, I am just nervous OCing above the listed speed, just as I don't plan to OC the cpu, either, because I feel like for my particular use the gains aren't enough to be worth risking lowering component lifetime.

    The actual listed specs on mine are indeed 15-15-15-35 and 1.35v, but what's weird is even though I have read that timings being the same like that on the actual specs is what means it will be Samsung b die, some kits have been shown as Samsung b die where the timings weren't the same... such as 16-18-18.

    I know you're talking about manual settings, but it just reminded me of that situation with listed specs.

    Nothing to be nervous about here. You won't hurt anything with those timings and speed on that RAM. You are almost guaranteed to achieve 3333 at 15-15-15-15-35-2T or even 1T timings at 1.35V with 100 percent stability. Really though, with already having 32 gigs of good quality B-Die, you are wasting your money with selling it to upgrade to 3600.

    Reason I was considering it was more that I was already worried the kit won't be stable because not all kits are the same even if Samsung b die, so just has me nervous.

    The RAM issues that Ryzen had are long gone now. When X370 came out, compatibility was a huge problem, along with RAM getting to at least reasonable speeds. When X470 came out, most of these issues were already fixed. With all of the BIOS and AGESA unicode updates that have happened for first and second series motherboards, all of these issues have been corrected. There is no reason for you to be concerned.

    So would you be 100% confident dropping 4000+ mhz ram into your X470 build?

    We are not talking about 4000 speed RAM. Where did I say anything about using DDR 4000 in an X470 board ? Nowhere, that's where.
