Yo guys, HP just swapped my old faulty SSD for a new SSD from Micron. Its model number is MTFDKBA1T0TFH-1BC1AABHA . Can you guys check and tell if its a really good ssd. BTW its a Gen4 SSD

Hi everyone. Here is a strange problem that you might be interested in. Welcome to send any comments and I will update my debugging process (and communication with vendors, if any and if possible). TL;DR for problem description If all those conditions are met: RAM is inserted in DIMM_A1 Stable Load (0 load or 100% cpu usage is okay, as long as it is stable) Then on my operating system (Linux 5.11.10-hardened), after each 5'14'' (which means 314 seconds, or 100 * pi), there would be an ECC CE (correctable error) on random page/bank at random offset. And here part of the log (in GMT+8): Apr 04 08:40:42 new_nas_server kernel: EDAC MC0: Giving out device to module amd64_edac controller F19h_M20h: DEV 0000:00:18.3 (INTERRUPT) Apr 04 08:45:54 new_nas_server kernel: mce: [Hardware Error]: Machine check events logged Apr 04 08:45:54 new_nas_server kernel: [Hardware Error]: Corrected error, no action required.

Ways are (DO NOT TRY THIS AT HOME IF YOU DON'T KNOW IR SOLDERING): Loosen/Tighten CPU cooler screws Bend the board at less than 2 degrees Read the whole BIOS settings, related manuals, but found nothing looks reasonable for me Suspects I think at least one of those parts is faulty (sorted by possibility based on current findings): Software problems, including The default BIOS settings for this motherboard will cause false alarm for Linux MCE related subsystem The default BIOS settings cause the data being changed without properly set ECC bits Linux MCE things is just not working on Ryzen ...... Software problems is really possible, since 314 seconds looks like something periodic, not random CPU memory controller for channel A (mc0) is broken (which means, RMA ). I think in Ryzen, memory is directly connected to CPU and if I put memory on channel B (maybe another MC?), runtime error disappears. So mc0 seems suspicious. RAM is not stable DIMM_A1 is much shorter than B1 so due to some magical physical things (reflection, etc.) an unstable RAM is possible. Additionally, the vendor of this RAM is also suspicious, and I have never brought things before. Motherboard trace is broken, including traces from A1 to CPU, B1 to CPU, and the DIMM slot to motherboard This is reasonable because when I got the motherboard, the package seems treated violently, although the internal box seems fine. CPU Socket connectors are not in good contact Least possibility. By the pinout diagram (source), MA_* pins are really near MB_* pins, and even located more insider. Affected by EMI Can't explain why B1 works. No high-power devices working near me. To-Do List Try if Windows (PE) have same system logs (if they can generate any, hehe) Re-plug CPU Contact AMD and ASRock for help since I'm not sure if this is really some hardware problem Try a new memory Try a new CPU The most interesting thing is: Why 314 seconds? Is this a periodically thing, or I just treated it wrongly? In my experience of R&D, even if I need some counter for, like drawing an circle, I would use 2**n instead of pi since this is how binary works. Oscillators generating sin wave also don't really use pi, although the sin function have some historical relationship with it. This makes me think maybe those CEs are some software bugs, not hardware problems. But why would this happen.... I spend about 16 hours continuously to change sockets, read kernel source code... but still have no idea about it. Anyway, thanks for everyone's help and I hope if you have met things like this before, you could give me some instructions. It would be better if some engineers from AMD, Micron or ASRock is interested in this. Totally pi**ed off, izumi_konata

Hi everyone. I have a ROG G531GT laptop. Today I received a new SSD I bought to change the 512GB Micron drive for a Crucial P3 1TB. After changing it, I couldn't get it to the BIOS. It got stuck with the logo. I've tried updating BIOS, disabling Fastboot and secure boot, and anything I could try. I know the drive isn't faulty because my desktop recognized it, and the drive slot isn't busted because it boots with the ld SSD and a WD 750 500GB SSD. I've read that the Crucial P3 uses NVME 1.4 while both the Micron and the WD use NVME 1.3. I think this is far from baing the actual problem, but who knows at this point. I'm lost and out of ideas to try. Any suggestions? TIA

I recently picked up a kit of Crucial Ballistix 32GB (2x16GB) 3200MHz CL16 DDR4 (BL2K16G32C16U4W) memory because it was on sale for only £83 during Black Friday. I was hoping to get dual rank Rev.E but apparently crucial have moved away from that so instead I got single rank Rev.B. I couldn't find much online about overclocking this specific kit as most seem to be using the 3600MHz CL16 kit, and most Micron overclocking guides relate to Rev.E since that seems to be most popular. Has anyone attempted to OC this kit or one similar to it, and if yes what frequency and timings did you manage? I know it won't be as simple as copy and pasting the settings but a general idea would help. I've currently got this kit running at XMP settings with Command Rate 1T and my CPU in Gear 1 mode CPU is i5 12600KF and motherboard is Gigabyte Z690 UD DDR4 with the F3 BIOS

Summary "Micron chose to exit 3D XPoint manufacturing due to lackluster demand that the company said had 'insufficient market validation to justify the ongoing high levels of investments required to successfully commercialize 3D XPoint at scale.' The company recently divulged that it lost $400 million this year alone due to the lack of demand for 3D XPoint." Looks like the supply of Optane SSDs and DIMMs is going to dry up soon. Quotes My thoughts Intel still has a very small amount of production capacity in New Mexico. However, this is a strong signal that even Intel is losing interest in 3D XPoint.

Earlier this year Samsung introduced its D1z DRAM for mass production. Quote :"Samsung Electronics has developed its D1z 8GB DDR4, D1z 12GB LPDDR5, and 16GB LPDDR5 DRAM devices as well with higher performance. We found both of the latter two devices (the D1z 12GB and D1z 16GB LPDDR5 chips) in the Samsung Galaxy S21 5G series; S21 5G, S21+ 5G and S21 Ultra 5G just released in January 2021."[1] These devices are based -almost entirely- on EUV. EUV is known to have some problems, especially when it comes to yield and chip throughput ,and especially at Samsung foundries. However, Micron chose to avoid EUV for their new DRAM (for whatever reason, which very likely relates to EUV machines availability ). Micron announced its first 1-Alpha DRAM for mass production, which is marketed to offers: "a 40% improvement in bit density and a 15% drop in power consumption compared to 1Z" [2] Thoughts: This approach is very interesting, as it could lead to "EUV free" process flow that ultimately helps with the global IC shortage. Although the crucial and most important details about the 1a process are not published yet.

I just have a ssd, the model number is mtfddav256tbn-1ar1zabyy. Is this better than wd green, Kingston a400 and pny cs900?

surce: http://hexus.net/business/news/components/107617-micron-dram-factory-mishap-taiwan-results-fab-suspension/ I thank the makers that I managed to get 16GB of DDR4 on 1/2 the price of the same kitt you can buy today suspect this global DRAM supply problem to last well into 2018 and probably 2019

http://www.anandtech.com/show/10932/kaby-lake-systems-with-intel-optane-ssds-coming-soon Honestly, the size doesn't concern me. OS boots are not QD 16+ workloads, and Intel's Optane products already significantly beat out Samsung's very best SSDs where it counts: QD1/2/4. Booting will be snappier even if on paper it doesn't look like it should from mainstream SSD marketing material. I'm not in the market for a new laptop and won't be for another 3 years probably, but I can't wait to see the reviews.

I have a system with 16gb of ddr3 ram laid out in 4 sticks of 4gb. I have one crucial ballistix low profile, two crucial ballistix sport ram, And my concern one old stick of micron ram screenshots of cpu-z below -Is the new ram being held back by the old stuff?

Hi I just upgraded to a 3900X and bought some Corsair Vengence RGB Pro 16GB (2x8GB) 3600Mhz. I wanted to tighten the RAM timings as I want to get all the performance avalible. Anyways. To figure out what I should set the RAM timings at I'm using the DRAM Calculator for Ryzen tool. So I go in and select what generation CPU I have and so on but I'm also asked about what Memory type I have. I went looking in the BIOS but the only thing I could find was that the manufacture is Micron and the software has 5 different Micron options... TL;DR I need to know what Micron memory is used in the Corsair Vengence RGB Pro 16GB (2x8GB) 3600Mhz kit.

Hello guys and thank you for letting me join this forum, So I would like to upgrade my RAM, currently I am running this: Crucial Ballistix Sport LT BLS2C4G4D240FSB I would like to upgrade with this: Crucial Ballistix Sport BLS2C8G4D240FSBK Since the "LT" is missing on the ones i would like to buy and the product names differ a little, I am not sure if this is going to run fine. The reason why I would like to know is because I can get the upgrade for a fair price. Thank you for reading and have a good day! Max

Hi! So i've seen alot of people recently say micron e-die is very good price per performance. I am planning to build a new ryzen setup with 3600x or 3800x ( i really want the better binned chip in order to reach maximum pbo). I was originally planning to go for flarex 3200cl14 and oc to something like 3600cl16 or even better if i could, which seems almostr guaranteed with samsung b-die. However, I now am starting to look at ballistix sport 3000cl15 if i could get almost the same oc there. I know it's possible to reach high speed, but is it likely or just luck of the draw? I would like to get to 3600cl16 Thanks in advance!

Which one do you think will overclock better with a 3900x ? (mobo : b550 aorus elite) Apparently micron is better for ryzen 3000 end b550 mobo ?

Summary GDDR6X is real and runs at 19-21GB/s, developed by Micron. Also first official mention of the 3090 naming scheme. Micron: In Summer of 2020, Micron announced the next evolution of Ultra-Bandwidth Solutions in GDDR6X. Working closely with NVIDIA on their Ampere generation of graphics cards, Micron’s 8Gb GDDR6X will deliver up to 21Gb/s (data rate per pin) in 2020. At 21Gb/s, a graphic card with 12pcs of GDDR6X will be able to break the 1TB/s of system bandwidth barrier! Micron’s roadmap also highlights the potential for a 16Gb GDDR6X in 2021 with the ability to reach up to 24Gb/s. GDDR6X is powered by a revolutionary new PAM4 modulation technology for Ultra-Bandwidth Solutions. PAM4 has the potential to drive even more improvements in data rate. I'm surprised we're getting GDDR6X this soon, it feels like we just got GDDR6 yesterday.

Hi! I'm building a new pc and wonder what the benefits are of nvme over ssd ? My old pc had a 1tb wd green, and a 250gb wd blue as the ps drive. Other than My fans and gpu the next most noticible noise is my hdds. So I was thinking of going add ssd! I was looking at a 480gb adata spg sx8200 Nvme drive with a 1tb wd blue ssd sata 3 drive. Or for around the same price doing a 250gb we blue ssd sata 3 with a 2tb micron ssd. The first combo comes out to be about 330 bucks( based on pcpartpicker) the second option is about 370 bucks. Both are all ssd setups, what I'm asking is would I be missing out on the nvme speed for the extra storage? The only experience I have with ssd's is my wife has a lenovo yoga with a 512 nvme drive and I love how fast and quiet it is! Thanks for the help!

It's been a hard time on memory makers with selling as much memory as they can produce, however a new class action lawsuit out of the US District Court for Northern California is asserting that Samsung, Hynix & Micron have been price-fixing DRAM prices. According to the lawsuit, the companies actions have resulted in 4 GB DRAM prices increasing 130% from July 2016 thru February 2018, while the companies more than doubles their revenue between Q1 '16 and Q3 '17. It is also alleged that even though DRAM prices more than doubled during that time period, the production costs did not increase and there have been no process changes to justify the price increases. https://hothardware.com/news/samsung-hynix-and-micron-dram-class-action-suit-collusion ... If the Hagens Berman name sounds familiar, it’s because it was the firm responsible for securing the aforementioned $300 million settlement against Samsung and Hynix. So, it has the experience in this type of litigation and the investigative know-how to see this case through to its eventual resolution. “What we’ve uncovered in the DRAM market is a classic antitrust, price-fixing scheme in which a small number of kingpin corporations hold the lion’s share of the market,” said Steve Berman, who serves as managing partner at Hagens Berman. “Instead of playing by the rules, Samsung, Micron and Hynix chose to put consumers in a chokehold, wringing the market for more profit.” While I think there may be a grain of truth behind the case, I'm not sure how much traction it will get since memory is definitely in high demand and iirc these companies have also been working to open up new Fabs which have associated costs that might not be accounted for in this lawsuit. Either way, it should be interesting and maybe we'll see DRAM prices drop a small bit.

http://www.guru3d.com/news-story/intel-silently-shows-unannounced-1tb-bga-ssd.html I'm hoping that image renders, as I'm on my phone atm, which means I can't select text on guru3d either to paste a quote. However, the author speculates this is the new Micron 64-layer BICS 3D NAND, and mentions the possibility that this could be embedded in a phone or used to make future 4TB M.2 SSDs. This reveal had no leaks whatsoever, and a release date is not yet given. Still, woohoo innovation! And hopefully this means the NAND shortage is entering its final stage.

So I built myself a PC a few months ago (full specs below), and the RAM I bought is the Patriot Viper Steel 3866MHz C18 (2×8GB). It is a bit expensive but the reviews were very positive about it. The units that were sent to online reviewers had Samsung's B-Die chip which is basically the best performing type of RAM at the moment. However, using Taiphoon Burner I discovered that the one that I received is actually manufactured by SpecTek, a cheap sub-brand of Micron that produces low-cost memory chips. The actual die type is unknown. This is probably just Patriot trying to mislead customers to sell cheaper RAM at a higher price. Their own website, in fact, does not mention the die type for that RAM model. Luckily, I was able to apply XMP normally and make it run at the advertised frequency, even though some memory sub-timings seem a bit high. This is what HWiNFO shows: Tcas: 18 Trcd: 21 Trp: 21 Tras: 41 Trc: 87 Trfc: 653 Also, UserBenchmark shows a RAM score of 92% and latency of 70ns which is worse than what some cheaper 3200MHz C16 RAM sticks can achieve. I didn't care at first because I mostly play Rainbow Six Siege and it was running fine. This week I downloaded CoD Warzone and Ori and the Will of the Wisps, and both games stutter A LOT. The framerates are high but there are constant frametime spikes while playing (I checked using RTSS). I have a theory for this: since both games are "open world" environments, could it be that my RAM is slow at loading/unloading game data and therefore creating those stutters? This would explain why it doesn't happen in Siege since the whole map is loaded once before the game starts. Could this possibility be what's happening? Or am I on the wrong track?

Micron has acquired Tidal Systems, a company specializing in SSD controllers founded in 2014 by industry veterans from companies such as Sandforce, SK-Hynix, and Skyera. This acquisition finally completes Micron's portfolio - they can now make all three vital components of an SSD; the NAND, DRAM, and SSD Controllers, all in-house. Samsung is the other SSD manufacturer that can do this, and now that Micron can as well, it might mean some serious competition may be coming in the SSD market soon. Quote from KitGuru.
