Samsung Green 30nm Memory Test

[parsec]

Re: Samsung Green 30nm Memory Test

I recently tried this Samsung memory, and I find it to be a fascinating product. It's unique in many aspects:

No XMP data. Not that it's necessary, but unusual to be missing.

Low operating voltage potential. I can run 16GB at 2000, 10 11 11 28, at 1.35V, all other voltages standard.

Broad compatibility. A boards memory QVL or Support list is required reading, and is not a suggestion, but a shopping list IMO. But this memory, just put it in and it works. That is unique in my experience.

Super low profile. The locking tabs on my DIMM slots are higher by ~5mm than the top of these DIMMs when installed.

Unmatched DIMMs work together. I used one 2 x 4GB DIMM kit with two single 4GB DIMMs, Serial numbers are all different, even in the kit. Did that on IB and SB PCs. Can you imagine what matched sets could do?

Odd SPD data. As some screenshots in this thread confirm, various hardware info programs show some differing values for this memory. CPUz show 1.28V in it's SPD tab, while others show 1.35. A program bug or more non-standard behavior?

The low voltage operation of this memory thrills me for some reason, I guess because it goes against the grain of the usual "more voltage, more more..." thing. That is great for IB CPUs, which are happier with lower memory voltage. IMO, this product is the rebel of memory, decently OC-able, no heat sinks or fan nonsense (OMG ) and no compatibility questions.

I wonder if these Samsung 30nm memory chips will be sold to the usual memory "manufactures", or already are?

I see this memory is working on X58/i7-9xx platforms, which IMO is one of if not the first system that is extra fussy over memory compatibility. Plus the "missing memory" issue that many users of that platform may have (me too.) It just makes me smile even more knowing that this memory works with it just fine.

Re: Samsung Green 30nm Memory Test

i tried with 16gb all matching kit,it made no difference for me,clocked exactly the same as a mixed batch

Re: Samsung Green 30nm Memory Test

Hey fellow Brummy, did you ever manage to get that Samsung memory any higher than 2133MHz? Any luck with looser memory timings or higher voltages?

I have been considering purchasing some myself for a new build with an Asus Z77 chipset mobo and i7-3770K CPU. The low profile nature appeals to me and so does the low voltage. However I would like to overclock it as high as possible when needed. Running 1600MHz and 1.35V would be fine most of the time.

I need to make a decision on this today and get some ordered so it can be despatched on Monday.

Re: Samsung Green 30nm Memory Test

it can do 2200mhz on my gigabyte z77,but the read/write/copy figures tend to drop off,[email protected] voltage tend to be the sweetspot

for the price it costs nothing comes close to this ram, id expect 2133mhz to be your highest speed,some have achieved 2400mhz but that was on the x79 boards,currently have two 8gb kits @2133mhz on a z68/z77 board

tbh i dont see any point going higher than 2133mhz speeds other than benchmarking

Re: Samsung Green 30nm Memory Test

Hi all,

Can someone give me some clues to help me break the 1866Mhz barrier.
ga-z77x-ud3h (see my specs)
Bios:f20c
3570k
4x4GB (16) GB

I have no problems at:
1600 Mhz: 8-8-8-22 1T 1.35v (auto for everything else)
1866 Mhz: 9-9-9-24 1T 1.5v (1.488v read) (auto for everything else) (currently running with this)

I boot at:
2000 Mhz 9-10-10-28 1T 2T 1.5v (1.488v read) (auto everything else)
but it is not able to boot on the next power up. It's reverting back... even if I put 100.1 Mhz for BLCK...whyyyyyyyyyyyyyy

According to that site:
[Sammelthread] Samsung Green MV-3V4G3D DDR3L-1600 CL11-11-11-28 LP (OC-Geheimtip?)

There is way more room to go.


I completely gave up on 2133 Mhz

I tried 2400 MHz 11-12-12-31-2T ...1.5v (1.488v read)... almost booted but ...no love..but almost

Any help on secondary timings or other tweaks or even the best BIOS version for mitigating the hurdles... will be appreciated.
I haven't played at all with vtt...load clib and stuff like that.

Many Thanks!

Re: Samsung Green 30nm Memory Test

you need more dram voltage !!! don't be scared to use upto 1.65v with 16gb

then try 10-11-11-24-1t timings for 2133mhz

might need cpu/vtt at 1.10-1.15v also

you wont run 2400mhz,most you'll run is 2133mhz

[Teddybehr]

Re: Samsung Green 30nm Memory Test

LOL
Of course I'm scared xD Those are to be running at 1.35v
In any case ...thank you for encourage me to break the 1.5v scare.

Well I hold my breath, took a leap of faith and I tried @2133Mhz 1.65v
9-10-10-28
10-11-11-24
10-11-10-28
10-10-10-28

Nothing

I have manage to get 2000Mhz 1.6 v
9-10-10-28 fine (like other people did in the link although at lower voltages)

Also set starting speed for graphic card slot manually at Gen 2 (in my case). Seems to help.
Look like it's holding settings at this voltage

I got to go 2133, 2200 or even 2400
That would be a shame and an insult to those little marvels not to

Any other suggestion (bios version, voltage, timings, sec. timings...) will be appreciated !

Re: Samsung Green 30nm Memory Test

it could be down to 16gb

with 8gb you would do 2133mhz easy

try loosening timings more so maybe 11-11-11-24-1t did you use more cpu/vtt? max safe is 1.2v so anywhere from stock 1.05v to 1.2v

Re: Samsung Green 30nm Memory Test

Thanks but I really need 16GB.
Your advice for vtt worked for stabilizing the ram !
I read that on Gigabyte board vtt should be 0.005v above icm. I gave it a try.
vtt: 1.05
icm: 1.045

Now able to do 2000Mhz @ 9-10-10-28 with 1.5v (instead of 1.6v)

With those same vtt and icm voltage, I tried 2133Mhz and 2200Mhz, 2400Mhz (1.6v)...still no go
I think I am having hard time find the right timings for those speeds with 16GB. Actually for 16gb, I haven't found anyone that did 2133Mhz... ever.

I will take a break for one week because my ears are still buzzing with the "KloK" noise that the board do while rebooting (so many times...soooooooo many times).

People with x79 or z77 from other manufacturers board (let say Asus) seems to do better (2200Mhz,2400Mhz 2600Mhz) than us on Gigabyte for those ... but I would not change for any other manufacturers.
I will try any other advice you have.
Many thanks again Sir !
