[@dsandoval9396]

What CPU are you using? Are you overclocked? I have 2x8 TForce Vulcan Z 3000 (with xmp profile, but stock is 2400). Because of running apps and games I find I might need more memory, looking to get 2x16. Anyway, I was told by the PC manufacturer (as I have a prebuilt) that my Ryzen 7 3700x, B450M/ac mobo, only supports RAM at 3200MHz at the fastest. I heard on a forum that it's possible to go faster with RAM but then you'd have to start playing with FCLK and I'm still to new to this to be messing with that so it looks like I'm stuck with 3200 RAM for now, not that I'm complaining.

I have no problem buying Klevv here in Melbourne Australia. I'm only running an R5-3600 CPU, on a TUF X570 wireless board. My RAM is Klevv c16-3200, I have 4x16GB (64GB) sticks which I am running at c16-3600 at 1.35v stable. All I've done is change the frequency, all XMP timings are untouched otherwise, including voltage. I've found this to be a nice stable balance, although I've managed to run them at 14-14-14-42-3800, with IF at 1900, with a few other timing tweaks, with 1.5v , but I'm not comfortable pushing it that hard, and it can be a little flakey at those settings. I sold some Samsung B-Die (4x8 Hyper-X c19-4000) which could only do c14-16-16-46-3600 at the same settings I'm using for the Klevv sticks, on the same board. Being Zen2 it certainly wouldn't run 4000 regardless of settings, even pushing as much as 1.8v into it. I couldn't do better than 1850 IF with those sticks either. I could run the B-Die at 3733 at best, but a bit flakey. My Klevv RAM is CJR Hynix. I'll be buying a 5900X when the dust settles, and I'm hoping to get a little more from my RAM. What is your opinion of CJR Hynix and do you think it likely that I'll be able to push it a bit harder with my current mid range board and incoming Zen3?

[@videocardzrule354]

High quality DDR4 is so important!. For the first time in my life, I spent $439.99 dollars on my 32GB memory kit. I got sick of black screens with even the tiniest of memory adjustments in the bios on my old memory set. I purchased G.Skill Royal Z 4x8GB DDR4 4000Mhz CL15 with 1.5 volts XMP profile. They are phenomenal! And well worth $440 bucks. With taxes and 1 day shipping they were almost $500 dollars. These are high quality binned Samsung B-Die using the A2 PCB design. I run a delidded 7980XE at 4.8Ghz on a X299 Dark motherboard. So I wanted the best matching 4,000Mhz quad channel set I could find with the lowest possible timmings. And CL15 4,000Mhz was the absolute best I could find. I have optimized the timmings and secondary timmings quite a bit, and I can even run 14-14-14-32-1T-290 at 4,000Mhz with 1.6V. Very very very fast! Very low latency! It is stable in my day to day usage, and very fun for benchmarking and gaming. I have managed to get 15-15-15-340-1T/ 4,000Mhz 100% memtest stress stable which is more realistic for daily usage, better get a fan pointed on them though! They can hit 55-60C, and lose stability. A matching quality memory set is the most important part of a build! And I will never cheap out on memory again! Thanks G.Skill for offering such a cool and well binned kit, but I certainly paid for it though! And thanks Buildzoid for providing such helpful information. Don’t buy K SKU processors, and then cheap out on memory people! You are wasting your time. Latency and bandwidth is important.

[@Olivia-W]

I just got started on my better memory journey. Snapping up some last-one-in-stock discounted B-dies and pretty happy about it. On a side note my kinda crappy CPU performance may have in fact been caused by crappy memory...

[@andrewryder3075]

Just to correct a (slight) inaccuracy - Micron did not "buy" Crucial. Crucial was a brand created by Micron (September, 1996) specifically to market their DRAM direct-to-consumer. It has always been owned by Micron. I still have some old SDR sticks which are Crucial-branded with a "by Micron" logo in small lettering underneath.

[@gordonlawrence1448]

The reason DRAM is referred to in bits rather than bytes is historical. The earliest 3 generations of DRAM were all in a bitwise configuration. EG the 4104 (4kx1) 4116 (16kx1) and 4164 (64kx1) all of those fitted in 16 pin DIP which would not have been possible for bytewise. It was only with 256kx1 that things changed and a 46464 was made(64kx4).By this time the chip could not fit in a 16 pin DIP anyway so going for a few more pins was not as much of an issue. Remember back then there was /RAS, /CAS, /RD, /Write, /Refresh and /CS. The /Rd and /Write pins got changed to a single Read/Write quite quickly for the 4164 and I think some variants had RAS/CAS to keep them in a 16 pin DIP instead of 18 but it's decades since I designed with them.

[@mbelle2055]

If you want to use Zen 1 on a X470 Gaming Plus Max (daisy chain) and somewhat high memory clock with using all 4 DIMM slots, please use "Bankgroupswap enabled" and "Bankgroupswap_alt disabled". This changes "blackscreen and no boot" to "working without errors" on my system for some reason. I have got 4 Samsung M378A1K43CB2-CTD C-Dies. 2 sticks are from week 35 / year 19, the other 2 from 23/18. They come with DDR4-2666 Cl-19 out of the box and all can do DDR4-2800 with 14-16-16-34-52 and 1.29V (geardown and bankgroupswap enabled). Any higher clockrates are not possible, no matter the timings or voltage. I am possibly running to the limits of Zen 1 with 4 used DRAM slots or board signal quality limit. ... could be worse. :)

I can relate to the statement of 3200mhz cl16 kits using everything under the sun. I bought a ripjaws V 2x8 cl16 kit proceed to get some variation of micron memory and one stick flatlines on its stock xmp profile(actually it needed 1.5v to reach that which looking back after a year YIKES)... which is great, microcenter was nice about after the one month it committed sudoku they give me an exchange ripjaws V kit, I proceed to get 8gb bdie in it and it has had no issues rn at 3600 mhz cl14/5, I would go further but a 2600x imc can only do so much. Recently I had a post error which I couldn't figure out what the issue was so I cleared cmos because nothing was fixing it, my bet is this 2600x has the silicon equivalent of having a screw loose and its just making an issue for no reason

In South Korea, samsung sells C-die oem sticks at very cheap price. (compared to other manufacturers binned kits) So we tend to use a lot of those. And it is okay, especially for zen2 systems. Most c-die oem sticks usually go up to 3600 CL18 and often up to 3733~3800 CL16~18. Which is a good spot for a zen2 system.

[@glassius85]

Loving the videos, really makes me want to see how far I can push my memory. Even if it means "blowing" the sticks up. But I'm running into a wall I hope someone can help me with. I have a couple of sticks of 8Gb B-die, rated at 3200 CL14. I had problems getting as far as I wanted because anything over 1.45v would crash because of the temp going past 50C. Added aftermarket cooling and now the sticks never goes above 35C which has allowed me to push it quite a bit further, but I'm now running into a wall when trying to push the voltage past 1.6. Even at XMP speeds it's unstable at 1.65v. I've tried lowering the VTTDDR, but that didn't seem to help. Any suggestions? Are there any other settings that might allow me to push the voltage any further? Or is it the memory controller, motherboard or something else that is struggling? Other specs are Ryzen 3700x on an Asus Crosshair VII Hero. Btw, my current best result is 3800 14-16-16-14-28-288-1T. I wanna keep it at 3800 since I'm running the memory controller and IF at 1:1:1 and I can't seem to push my IF any further.

[@photonboy999]

STOP!! Raising the voltage to the memory also raises the voltage to the memory controller in the CPU. You can and WILL kill your CPU if you go above certain voltages like 1.45V (can't remember the recommended values right now).. it's not linear either as you might get three years at a certain voltage and a little more drops it to one year then a little more might give you a month or whatever... and your ACTUAL VOLTAGE might be much higher than the reported voltage as well so be really careful... so again, you aren't just risking damaging your memory but also the CPU... and you've taken things pretty far anyway... why do you want to push further? It's unlikely you'd see any real-world performance gains so do you have some ARBITRARY benchmark result you're aiming for?

[@marceldiezasch6192]

The timing is 16-18-18-36 which I gather is considered a bit loose. According to this video, this memory could have crappy memory chips on the PCB. If I'm not overclocking then is there anything I should be worried about? Also, I have a Z390 board which is dual channel but I have 4 x 8GB sticks.

How high dram voltage can i run on my z170 board? 3. will i get noticeable increase in performance by going beyond the xmp of this kits? 4. will the 6700k benefit from frequencies past 3600 (if it can even run those)?

Hi Buildzoid I think you made a mistake, the A2 PCB version of the Team Extreem only has a 8 layer PCB if you look closely and it is the same one as the Antec S3 bdie kit you have which has a 8 layer PCB. I managed to have my Team Extreem 8 pack edition with A2 PCB RMAed in the past and got a 10 layer A0 version in return after I made a complaint to Teamgroup about this though Teamgroup never admitted about that. Interestingly I noticed their marketing material no longer has 10 layer PCB in the Team Extreem marketing material shortly I got my kit from RMA.

Hello bz. I'm trying to break new 2400g records, but my asrock board's bios (i hope whoever designed the bios perishes in hell) doesn't make it clear what is what. There's apu gfx voltage, vid soc voltage, vddcr soc voltage, and a strange multiplier which seems to use a multiplier. Now, what in the goddamn do those things do? I wanna give my imc more voltage, but since i'm already running 1.4875v on the gpu i'm scared of potentially shoving 1.7v into vega cores. There isn't much documentation on internet. So what do you suggest?

I started this video in my BR, left the house to go have a colonoscopy, came back and it was just wrapping up. Thank you for the long-form videos. Apologize to NOBODY for it.

It's been two years since Samsung chips has been used on any Crucial parts. It's all Micron now.

[@blazetechstuff]

ill grab some of that nanya（南亚） to test,. saw a review, cl16 3600 at 1.45v. eh levels of stability.

[@lukasva77]

g.skill 3800 cl14 how does that bin compare to like that viper steel that buildzoid tested 365 euro vs 145 btw

[@OGNG696]

What is better for Intel Micron, Samsung or hynix?

[@CasualGamers]

From my experience, the only chip from Samsung OEM that is consistent is E-die 22nm on 4gb single rank server style pcbs. I've binned about 20 sticks in pairs, from different purchases and I think only one of them was not able to do 3866 without errors. Typically they do it at c19, but can go lower. It's not bad considering how cheap it is and works good for budget ryzen zen1/+ 3466/3533c16 . Small sample, but worth a shot if anyone is looking into playing with memory, it's a fun IC.

[@bronzeagehuman]

Even if it's not cost-effective because other components could use the budget, I'm always obsessed with getting top-binned b-die somehow.

[@kainhall]

my question is.... why is the "slot interface" shaped like a very shallow U?? . like... why are the edges the shortest.... and the middle the tallest?? . is it just to help with alignment / insertion into the different designs of RAM sockets? or is it because the middle part is power or data.... and it helps to have more surface area to contact with? . like.... im sure its a JDEC or ISO standard shape.... because EVERY stick is like that but why?

[@_--_--_]

They use Gbit, because a 8Gbit chip equals a 8GB single rank module or a 16GB dual rank module. Eg a ECC 8GB single rank module uses 9x512MB chips, but the chips are 8Gbit, so 8GB module for single rank in this case. Like always with units, you try to use the unit that makes use for the intended application as simple as possible. Its just more intuative.

[@techbuildspcs]

I see my xtreem kit there :)

[@BrianMartin2007]

How about that G.Skill DDR4-2400 14.14.14.34 F4-2400C14Q-64GVK kit.... thoughts? Bought it 3 years ago.

[@OMGJL]

One thing I say different than BZ, about the 3200c16 (or even lower) memories---------- Some are worthy to buy, but you only buy when you know how to take the risk. Samsung B Die request binning since not all B-Die ICs are consistent, but Hynix CJR/Micron Rev E both are relatively consistent and mostly clocks pretty well. Let's put some example here: 1. Crucial green PCB 8GB 2400 -- Some using "C9BJZ" and "D9VPP" ICs, which both is Micron Rev E, and those without binning, will most likely do 3600+ to even 4000+, with tCL16 and tRCD on 20+ 2. Kingston ValueRAM 8G 2400/2666 --- Recent batch are mostly Nanya A Die, which most likely does 3200C16 or 3600c18. Buying cheap low end RAMs and get 3200 is not bad. 3. Kingston HyperX Fury/Predator (RGB/Non RGB) 8G*2 kit 3200, I see a good number of Hynix CJR combined with Nanya A Die and Hynix JJR, if you luckily getting the CJR you can push 3600c16/3733c16/ 3800c16/4000c17, if you unlucky and got JJR or Nanya, 3600c18. 4. Good number of Kelvv memory (child company of Hynix) are using CJR, which OC pretty well. 5. Corsair Vengeance 8G*2 or 16G *2 3200 speed bin, with Version 4.31 (Samsung B-Die), or Version 5.32(Hynix CJR) both likely clock pretty well. 6. All the recent batch of Thermaltake Ram I've touched (8G*2 3000/3200) are all CJRs. DO NOT BUY G.SKILL and try your luck at OC, G.Skill's binning process will out smart you, but Kingston/Corsair/Crucial/ADATA/etc do have certain model to try your luck with.

3. HyperX Predator RGB owner here. Bought two 2x8GB 3200 CL16 kits. Both have JJR. Aside from tRFC being worse JJR appears similar to CJR. Total cost about 200€ for 4x8GB. And yes i can confirm it does 3733 16-20-20-36.

[@OMGJL]

Raivo K Kingston is a bit weird there, some of the JJR was labelled as CJR, some CJR was labelled JJR....... some other was labelled correctly, I had a Kingston HyperX Fury 16g*2 was labelled as CJR, thaiphoon read as CJR, beheave exactly like JJR, does 3600c18 only.....

[@Raivo_K]

@@OMGJL Well then i might have mislabeled CJR because mine does 3733 CL16 despite thaiphoon showing all sticks as JJR. Still the tRFC does not match what the Ryzen DRAM Calculator gives me. The calculator does no have a JJR profile yet and the CJR profile does not match exactly.

[@OMGJL]

@@Raivo_K DRAM Calculator is only a "estimate", it's never going to be identical..... I found the DRAM calculator setting are quite optimistic, and often I need to bump up some latency by a tick or two.... Also regarding the "miss-label", I personally think it's Hynix that does it not Kingston, as Kelvv have sticks labelled as CJR and only does JJR performance too from time to time...

[@GrymSon]

I had same geil memory that died on me after 1 year, thankfully i got my money back :D they are pretty tho for a bare pcb design

[@el-danihasbiarta1200]

so how do i get 3600mhz with cl 16..when i could only buy OEM parts

[@dkrutsko]

So who actually creates these reference designs like A0 and A2? And where would one go to get them?
