Important Announcement for All PC Builders 🚨

[@Antantaru_]

Basically 3200MHz being advertised is actually 3200 MT/s which is equal to 1600 MHz so it’s clearer what you’re getting, since DDR means double data rate

[@alison90827]

This. They way they measure speed currently is actually twice as fast. A 3200mhz ram is actually 1600mhz ×2. But mt/s is the same old mhz we used to see

[@leechanyeong409]

Ok these 2 nerds above me were quicker than me to the comment but yeah (and why people place rams in a2 and b2 is a type of topology which is known as the daisy chain basically the 2 slots are faster but if all 4 rams are added they are a bit slower while t topology is all the same speed unless ram is different)

[@NickDoesCMPE]

Although this is right the actual read speed is half the "DDR" speed, this is because reading the data actually destroys it. The second (negative) clock edge is used to re-write the data just read (and destroyed by reading). This is because ram uses capacitors to store bits, reading causes the bit charge to be lost. Quick note, Double data rate does apply for writes, but not reads

[@Trooplee]

A RAM module with 1600MHz clock cycle and 3,200MT/s data rate may be advertised as 3,200MHz, which is technically incorrect. The practice has continued to this day. Some manufacturers fear the switch will make their RAM modules look half as fast without any change in specification. This is the easiest explanation I found from Google. Hope this helps.

[@ermac81]

so 1600MHz ram is sometimes advertised as 3200MHz and businesses don't like that they may not be able to do that anymore?

[@Trooplee]

​@@ermac81 Yes 1600MHz Ram with 3200MT/s data rate is advertised as 3200MHz which is incorrect. If they fear about there RAM modules looking half as fast if they told the truth, they should just change MHz to MT/s. Like rather than saying that tthe RAM is 3200MHz(irl it is 1600MHz), They should say the ram is 3200MT/s

[@HollowIchigoBankai29]

I am here for this change. I was actually looking into the difference last night.

[@l1ghtningcs]

It was always mts but people and brands started calling it mhz

[@MrStaplez]

Started over 20 years ago.

[@chrismannifield3222]

Yeah, MT on ddr5 is limited by processor speed. So it doesnt matter if its 6000mhz, its still only going to have the same transfer rate at the processor clock. In a round about way. I just went through this and proved it to a freind of mine with ddr5 4800 and ddr5 6000 with a I5 13500, the mhz rose, but mts stayed the same....

[@luciferhzd]

This has been happening since DDR 5 came out, they fixed the error, the correct name is MT/s, what happened is that MHz was used when those are half the amount of MT that the ram has, it was used years ago for pure publicity.

[@alexburlacu7931]

I don't want to be the bad guy, but I believe the problem dates back to even before ddr2. Edit: I'm not an expert too, feel free to correct me, but I'm saying this because I have friends that have lots of different gens of DDR and because at school we do this kind of stuff

[@drakendude5123]

It confused the f”k out of me when i was picking my parts and checking compatibilites with the ram, mobo and cpu.

[@TheDude50447]

When DDR was invented the main feature was that it could transmit data twice per clock cycle. So the actual Mhz were effectively doubled. Since there was basically no difference for the longest time manufacturers used the effective transfer rate as Mhz on the box while the actual clock speed was half. With Ryzen it became important again since cpu functions are now based on the actual clock of the ram.

[@SeeJayPlayGames]

no, I think it can be summed up by one Chinese phrase: 能骗就骗

[@Hunterkiller667]

Also it's not just about the base speed but the speed / latency combo.

[@SeeJayPlayGames]

latency literally hasn't gone anywhere for decades. When the frequencies go up, so do the latency cycles. Still in the range of about 8-12ns or so regardless of data transfer speeds. Has been that way since first generation DDR (or maybe even "single data rate" SDRAM, which I'm more than old enough to remember). Do something about the latency and you'll impress me. Until then, it's just half a scam.

[@jaydbd2457]

The issue here is that "3200 MHz" runs at 1600 MHz, but as it is double data rate... they just multiply that for 2 to get a bigger number, aka a marketing bs... which isn't 100% correct nor 100% wrong. Using mega transfers is way more honest, imho.

[@nialloftara5909]

Ddr dtands for double data rate. The speed in megahertz is half the effective data rate in mega transfers. Super simple

[@kingzyjhiepelongco3593]

8000MHZ (8 GHz) and above in the RAM speed can be so much better

[@theorphanobliterator]

DDR4 stands for Double Data Rate 4, meaning that on every cycle of the clock (Hz), the module transfers 4 words of data. so, 3200MT/s ddr4 would have the click ACTUALLY running at 1600MHz. but, lower Numbers tends to make companies less profit so they went with advertising it as 3200MHz. glad the shift is being corrected

[@326435ha]

It has to do with "false advertisement" as in ddr (double data rate) data is read/written on the up and the down wall of the clock cicle, what they used to do is double the actual frequency to ease comparison between ddr and sdr (single data rate) memory as a 200 hz ddr transfers data like a 400hz sdr so to avoid confusion they just doubled it

[@alexp5604]

I thought ram was measured in mega transfers but people would always get it wrong and say megahertz

[@SeeJayPlayGames]

it doesn't help when Task Manager in Windows propagates that inaccuracy

[@NicolasRiera-q5w]

What was happening its that ddr is basically doubling the acual frequency of the ram so 4800mhz is 2400mhz and so on, ram manufacturers use the higher number for marketing.

[@Dexruus]

Basically Hertz is a unit for frequency, which is partly time based, but the problem here is the differential of time to voltage changed (so voltage changes over time). But in the end you want to know the actual speed, so you want to know "data over time", which results in mega transfers. Key for that is, DDR (double data rate, ehich is achieved over using DOUBLE the frequency) which uses the same data lane at a the opposite frequency, so 1600 mhz would actually (important ESTIMATED) be 3200 mt/s and so on. I mean, technically you could also change the GHz on CPUs to Flops, but seriously why should we? :V

[@Donzaloon]

Engineer here… it’s because hertz (frequency) doesn’t change unless the source changes. Just like a 60hz TV will always be 60hz, doesn’t mean you are getting 60 fps. Same thing is applied to RAM speed.

[@arnavranjan1913]

Good change will help a lot of people.

[@aperson-qn8xn]

[@johlgren]

Windows are going to the manufacturers speed advertised today previous they were showing the clock cycle and not data transfer rate, DDR stands for Double Data Rate meaning it can transfer data on both ON and OFF cycle but the clock cycle only reports ON changes.

[@darthvail1]

It’s always been mega transfers but everyone just says hertz so that how they sell them. They are basically just labeling the ram correctly now.

[@insaneopinions]

1MHz is 2MT/s. That's where the Double Data Rate as DDR in RAM names come from.

[@gamer8622]

If you're buying ram off the big number on the box, you're doing it wrong anyway. You rly wanna focus on what speeds of ram your specific cpu/mobo likes best and then focus on timings. 6000mhz cl36 is slower than 6000mhz cl32, but most ppl don't read the cl number

[@calvinthompson1835]

Ddr(double date rate) 3200mhz is really 1600 MHz at a double rate

[@pixel4712]

Single data rate ram would have the same transfers as cycles, but a double data rate (ddr) ram stick transfers twice per cycle (transfers are double the hertz)

[@woobilicious.]

DDR means double data rate, when it was introduced for marketing purposes they "doubled" the advetised frequency to make it look better than similar clocked SDR RAM. using "MT/s" instead of straight up lying about frequency prevents a class action.

[@goku262002]

It is an end of an era I guess. But I mean logically it makes sense to call it Mega transfers but megahertz will always hold a special place I'll probably use old terminology until I die

im still going by clock frequncy as that is what matters. then how large each block is then affinity or any other features that push it beyond 3200 mt which clocks do. the ammount of transfers also depends on the system. its a way to make it seem its doing more when its not. marketing gimmik. people dont inderstand and jist go with the bigger number

[@sephirock9659]

[@c4n0]

Hz means electrical cycles, MT refers to data transfers

[@axelcastillo7432]

From what I’ve been reading, basically, RAMs nowadays transfer a megabyte of data per cycle?

[@SeeJayPlayGames]

no, they transfer 64 bits (8 bytes) per channel on both the rising and falling cycles. But they do it (hundreds or thousands of) millions of times a second. Which ends up being several GIGABYTES per second. For a current example, a 6000MT/s (3000MHz) DDR5 stick could thus transfer 48,000,000,000 bytes per second, or, dividing by 1,073,741,824 (because that's the actual number for a honest power-of-two GiB and I don't care what storage manufacturers think, besides we're talking about RAM anyway)... 44.7GiB/sec. Double that for dual-channel mode, for about 89.4 GiB/sec. Of course, that's theoretical; in practice it's a bit (probably a LOT) less because the CPU has to request and process that data and it can't just burst all day. But that's what a synthetic RAM speed test would say. Keep in mind that there is no storage nor any other devices in your PC that are that fast; that's strictly the CPU memory bus speed, which is (regardless of generation) the fastest link on the motherboard. The example I gave was for DDR5, and earlier versions (DDR4, DDR3, etc) are slower, but that's relative; all of them are blazingly fast when you think about it. Even decade-plus old DDR3-1600 (in dual channel mode) can move 23.8GB (25,600,000,000 bytes)/sec. And yet, they all have about the same latency... but that's another post.

[@OctagonalSquare]

its because RAM manufactures are advertizing their speed in MHz but that wasnt correct. DDR4 and DDR5 are "duel data rate" which means they have larger through put but the speed is advertized as the both channels combined. so if you had a ddr4 2000MHz card is actually 1000MHz on 2 channels

[@pikkuraami]

Hertz or MEGAHertz are practically meaningless metric, if you use any sort of coding on transfer. Which means, everything after SDR Dram shouldn't use it at all. DDR stands for Double Data Rate and means data being tansferred 2 times every clock cycle (hertz).

[@pikkuraami]

3200MHz is technically just "3.2 billion per second". It could be clock cycles, or samples, or transfers. With DDR ram, we mean transfers, but that's just a convention. If you called that same stick of ram 1600MHz, you wouldn't *technically* be wrong. The clock does run at 1600MHz. Changing the unit to " MT/s removes that ambiguity.

[@johndododoe1411]

Actually CPU registers and CPU cache are the fastest types . In a typical PC the ranking is: 1. Core CPU registers: About 1000 bytes per hardware thread running at full CPU clock speed . 2. CPU memory management cache registers such as the paging TLB, accessed as often as the actual memory to direct those accesses to the right place. Again its under 1000 bytes per hardware thread . 3. Level 1 cache, all memory access goes here first, CPU listings say how much is included . 4. Level 2 cache, slightly slower than level 1 and only deals with access not handled by level 1 . Still part of the CPU package . 5. Level 3 cache, one step slower and bigger. same story . 6. Actual main DRAM 7. BIOS flash memory, as small as will fit the BIOS code .

The Mhz value is also called the "effective" speed, as in, it's effectively equivalent to a SDR of that frequency The Ram IC Industry standard is Mbps, to show the actual data rate MT/s is a really pointless "um actually" thing imo, kinda stupid I just don't use units when talking about it, it will be 3200 DDR4(for example), since it's essentially a industry standard by itself

[@yournerdiness3135]

Not really, they're the same thing for SDR RAM. Basically, RAM operations happen on the rising and falling edge of the clock. Megahertz is the number of clock cycles, megatransfers is the number of total rising and falling edges.

The DDR in DDR5 stands for double data rate. Basically your ram sends 2 bits for every clock cycle. But back when this was new manufacturers hust doubled the clock speed on the box so consumers could easily compare speeds from single to double data rate ram. Tl;DR MHz was a white lie. MT is a new way of saying the same thing without lying

[@hyper_cs]

Change it to MBps or GBps, that would be ideal for understandability.

[@ItsHonski]

Maybe because its not an accurate reflection of its speed? SSDs for example, and marketed with their theoretical max sequential read speed. However, the mass majority of reads to an SSD arent sequential, they're random reads. The second issue would be channel config. Running the ram in dual, triple, or quad channel would effectively multiply the speed, and don't even get me started on Flex mode. Theres also things like timing to consider. tl;dr: MT/s is a better way of assessing the "speed" of a stick of RAM.
