Hi guys,
First deal so be gentle, this is the famous Samsung B die RAM at a reasonable price, not the best it's been but cheaper than the previous shopping express deal from earlier.

probably trying to pump their share price
Afterpay day will be a national holiday soon
Afterpay Day sales are on between 17-20 March.
Seems these were cheaper during last years Afterpay day. You’d think they’d be cheaper with DDR5 now out no?
If anything I'd anticipate they'd get more expensive as production of DDR4 stops as the market pivots to DDR5 but I could be wrong.
For the past iterations, prices tend to fall significantly right up until almost all stock of compatible CPUs and mobos dry up.
At that point the high capacity, mid/high+ perf DIMMs regain some value, but low cap sticks become completely obsolete.
Why would anyone buy pricy 'high perf' (i.e. overclocker's) 16GB DDR4 DIMMs right now? … I'm guessing only the people who already have two sticks and want to fill their other two slots, instead of a full machine upgrade. Pretty small market.
I had a look through and it would seem this deal is the cheapest for the Samsung B die SKU of this RAM. Model number ending in TZN.
Thanks for confirming!
3600C16 with tRCD 16 is definitely B-Die no doubt.
That's the model number ending in TZNC, its not the Samsung B die.
Ah gotcha.
What difference does the Samsung B die make?The timings on the cas latency are tighter so it's 16-16-16-36, basically better performance. I'm sure someone here with a better explanation can chime in 😁
@JoeBogan: My turn, if you buy B-Die because the primary timing is tighter, then unfortunately B-die isn't for you(unless you have extra cash to throw away).
auto timing 3600 16-16-16 vs 3600 16-19-19 is almost indistinguishable in terms of performance, B-Die is for overclockers, a max-tweaked B-Die will out perform every other max-tweaked IC.
a binned (binned refers as it's been "cherry picked" to ensure chip quality) Samsung 8Gbit B-Die is THE best DDR4 memory IC you can buy, not only it tolerate high voltage but also it scale VERY well with voltage, meaning as you pump more voltage at it, you will be able to tighten every timing a bit more, and/or push higher clocks.
Though keep in mind B-Die is VERY inconsistent, a binned IC could achieve very good result, but at the same time a not-binned B-Die could be really, really, bad. It potentially won't run any higher than 3200.
Way to find good Samsung B-Die is simple: tighter tRCD the better. (memory timing be like 3600 16-16-16-36 as frequency tCL-tRCD-tRP-tRAS)
Math: on XMP profile, do Frequency/tRCD, 225 is about a good average OC chip, ~250 or more is a going to be a really strong chip. Frequency isn't nearly as important, nor tCL. Then you check voltage, if you see 2 same kit that have same frequency/timing with different voltage, the lower voltage one is better, if you saw a kit with really tight tRCD, no matter how high the voltage it is, that's the better one. Lower voltage means POTENTIALLY more OC head-room, higher voltage means it POTENTIALLY endure higher temperature.
@OMGJL: Something to add:
XMP profile with Frequency/tRCD > 210 is almost always B-Die, in another word:
3200 14-15-15-35 is B-Die (low bin)
3200 14-14 -14-34 is B-Die(average bin)
3600 16-16-16-36 is a B-Die(ever slightly better than average bin)
3600 16-17-17-38 is a B-Die (low average bin)etc…., you can judge according to tRCD.
the only exception is Crucial Ballistix Max 4000 18-19-19, though its tight, but it a gold tier Micron die, not samsung B, and won't perform nearly as good as Samsung.
Basically….. Do you want a Ferrari GTC4 (GTZN) or a BMW M3 (GTZNC)?
They both will get you from A to B, both seat 4 people, both have boot space. But at the same time, there are differences between the two when you are pushing both cars hard at close to 100%.
Similar to the two memory kits, for normal use, you won't see much difference between the two. But if you are manually setting all your subtimings, and extract every last bit of performance, then the B-Die goes way ahead of the cheaper Hynix die.
Is this better than a normal 4400MHz? I am considering to replace my currently Aorus 4400Mhz with this B-Die.
19-26-26-46 4400MHz
VS
16-16-16-36 3600MHz
Check my comment above.
TL;DR is don't buy 4400 kit if you don't know how to manually adjust it.
4400 Mhz is not going to give more performance universally.
AMD 3000/5000, Intel 11th/12th gen with 4400 kit will result Memory Controller run at half speed (un-synced)
Intel 10th gen with a lemon memory controller might only do 4266, the really good one can scale to 5000+ (gold chip, top 1%) with a really good motherboard.
Intel 8th/9th gen is even harder to achieve higher memory clock than 10th gen.also 4400 19-26-26 is almost definitely using either Hynix DJR, Micron 8Gbit RevE or Micron 16Gbit RevB, any of the 3 is worse overclocker than B-Die.
Thanks for your helping.
I am currently running 4000Mhz with amd 5950x, and fclk frequency is 2000Mhz, is it get synced or not?
What speed you recon I can run on this b-die? oc to 4000Mhz is possible? b-die seems a lot potential on higher speed.AFAIK ~90% of Zen3 will spam WHEA19 error when memory speed running above(not include) 3800, but at the same time most Zen3 able to boot and even run memory test up to 4133/4266.
There is noticeable amount of performance loss running along with WHEA19 corrections, my recommendation would be running 3733/3800 no matter what.
Good setting (for beginner) would be:
SOC 1.15v, vDDP 0.9v, vDDG_CCD 0.95v, vDDG_IOD 1.05v FCLK:MCLK=1:1(asrock will show FCLK, if memory 3800 then FCLK set 1900, if memory 3733 then FCLK set 1866, 3600 then1800 )
Low bin B-Die: 1.45v~1.5v 3600/3733 16-18-18-36 GDM on, tRC 56, tRFC 400, tRRDs 4 tRRDL 4 tFaw 16 everything else auto
average B-Die: 1.45v~1.5v 3733/3800 16-16-16-36 GDM on, tRC 50, tRFC 350 tRRDs 4 tRRDL 4 tFaw 16 everything else auto
good B-Die: 1.5v 3800 14-15-14-30 GDM on, tRC 45, tRFC 290 tRRDs 4 tRRDL 4 tFaw 16 everything else auto (this is about Patriot Viper 4400c19 quality)
Gold B-Die: 1.5~1.55v 14-14-14-28 1T GDM off, tRC 42, tRFC 270/280 tRRDs 4 tRRDL 4 tFaw 16 everything else auto@OMGJL: hang on, I miss-read what u meant…. on this set of B-Die I recon its between average B-Die and good B-Die.
for your current kit I guess best u do 1.4v~1.45v 3733 16-20-16-36 GDM on, tRC 56, tRFC 580, tRRDs 4 tRRDL 4 tFaw 16 everything else auto
actually not too far off average B-Die, unless you can actually manage 3800 14-15-14-30 range.
@OMGJL: Thanks so much for your advice, huge help. I will try when I get twin pack of this ram. BTW, 2 sticks is easier to get 3800Mhz 16 16 16 36 then 4 sticks, right?
@getit: this is a dual rank kit, so if you buy 2 kit of these you gonna have huge trouble OC with quad rank.
@getit: Depends on your motherboard but I run 4x8GB 3800 CL14 no issues on a 5900X and B550 Aorus Pro V2 (very good at RAM OC despite being a 4 DIMM mobo).
In general, 2 sticks > 4 sticks in terms of OC potential but any decent mobo should be able to run 3800 with 4 sticks. As mentioned above, running 4 dual rank sticks will be a challenge so I wouldn't expect to have any OC headroom.
@OMGJL You seem to know your stuff. May I pick your brain?
I have 32GB (4x 8GB) of the Patriot Viper 4400Mhz Samsung B-Die. XMP will run 3600Mhz 14-14-14-34? no probs.
Tried running 3733 via XMP but it’s not stable, I suspect more voltage is required (not fully knowing what I’m doing I haven’t tried) and wondered:
- Is it safe without any direct RAM cooling?
- What actual benefit will I see from running that tiny bit closer to what I assume is perfection at 3733Mhz vs 3600Mhz?
- Is 3800Mhz more desirable than 3733Mhz?
Thanks in advance!
I don't get you about the running X frequency via XMP part, please elaborate?
Ryzen Mem OC benefit from both ram and FCLK, so raising MemClock is doing both so definitely higher clock the better..
4 sticks with 1.5v may require some cooling, depends on your case and how hot is your GPU.
I meant I’m just using the preset XMP profiles available, not manually tweaking each individual setting.
BTW if you trouble to run 3733 with 4 stick, it is either your motherboard being too average(you can try tweak ProcODT and it might do some magic), or you didn't raise your SOC voltage well enough.
SOC 1.15v, vDDP 0.9v, vDDG_CCD 0.95v, vDDG_IOD 1.05v
I definitely haven’t tried raising the voltage and think that’ll be the answer, but hesitant if cooling will be an issue.
Thanks for your help.
You could always ziptie a fan over the sticks or just sit a fan on the GPU blowing at the sticks
I have this strapped on motherboard blowing directly to my ram, and my gpu is water cooled, so I have my ram on 1.55v yet to see any instability about temperature, currently running 4266 16-17-17-34 tRFC 310,
I reckon 1.6v should also be fine on my stick, but I am a bit lazy now, and my AIDA64 latency is 38ns already so CBF lol
The thing is called RAM FAN VRM FAN M.2 Fan, I got it off taobao China and shipped over with a international courier
My 4400Mhz start with 1.5v, so 1.6v should be in safe range
Any average B-die should be able to do 3800 CL14 with less than 1.55V. I binned 4 Corsair Vengeance RGB 3200 CL14 sticks and all of them could do 3800 CL14 under 1.55V (daily stable ofc).
There are diminishing returns above 1.5V but if you were pushing really aggressive settings like 3800 CL13, 4000 CL14, etc 1.6V will probably be necessary. B-die can take 1.6V daily tho it's recommended to have active cooling.
Why so many deals coming with afterpay?
I don't even wann see their website lol
