Some of you have probably heard about this ram,and its ocing ability its samsungs world first 30nm green dual channel ram,rated at only 1.35v,so today my 8gb kit arrived and i though id post some results

the kits rated speed/timings at 1.35v are [email protected] 1600mhz,with a few minutes tweaking i was able to get this result using only 1.45v dram voltage,vccio was left untouched at 1.05v,i was using 2600k and z68 v pro mb,this kit will run at 2400mhz on x79 due to improved memory controller

i didnt want to push dram voltage too much but easily achieved 2133mhz

heres stress test results,please dont giggle at my temps!! i know they are poor for sb

http://i40.tinypic.com/10eofgm.jpg

a few minutes more tweaking resulted in 9-10-10-28-1t @2133mhz,timings and slightly reduced latency,all using 1.45v dram and stock vccio voltage of 1.05v

all in all im impressed at the performance esp using only 1.45v dram and the cost of just a little bit more than standard 1600mhz memory:facelick:

Very nice results! What tRFC are you using?

They can handle voltage if you want to give a little more to try better timings. If not, I understand, I'll have some to push on sometime soon! :thumbsup:

Just saw them again today somewhere here for $37 now I think, so I better grab a set soon before the prices get jacked up.

trfc is at 171,yeah they are rated at 1.35-1.5v i tried with 1.5v for 2400mhz with 11-11-11-28-2t but no joy,im just scared to use more dram voltage being 30nm,still the cheapest ram regarding performance though,i might grab another kit while they are cheap

Try higher tRFC if you don't want to use more voltage, that may help, and higher tRC might help too.

They'll be fine with more voltage though, I've seen people using 1.65V-1.7+ I'm gonna try to order a set this weekend I think if I have the spare change

my second kit arrived today,on offer in uk so i grabbed a kit,16gb total now,ill try and improve things,would love to run them at 2400mhz

you have to be real carefull getting them out of the packaging and in/out of the mb,they are very small and fragile

ohh so they are Italian ram? Made in Fragile? LOL

im used to ram with huge heatpipes on them,these things are tiny,i wonder how they would perform on x58?

Is this the ram? Newegg.com - SAMSUNG 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model MV-3V4G3D/US (http://www.newegg.com/Product/Product.aspx?Item=N82E16820147096)

comments look good on newegg. None for X58 though.

yeah thats it,just buy enough for dual channel or split one kit to make tri channel,ive pulled my x58 apart or else id test myself,need a psu to build it back up

I wish I could but money is tight right now. Had to break the wallet for the raid controller. But if anyone would like to send some this way I would be more then welling to try them out on X58 :)

I bet they are a beast on X58 with a 970^ CPU, or 1156 Lynnfield!

well idk if its linked to this faster ram but im getting very fast boot ups with ssd now, 4secs to logon 15secs to desktop,ill post pic when i find it

Ya, that's due to the SSD's mainly, as in 99.9% mainly :bdaybiggr

Well I just got some of this ram in today and after about 3-4 boots I have it clocked to 2133 mhz. I have not done any stablity test yet but here is a screen shot of it so far.
I maybe able to drop dram voltage a bit. It would not boot with 1.315 qpi/vtt but I did boot with 1.355 mainly do to having to run such high uncore speeds 4256mhz :FIREdevil

I am a complete noob when it comes to overclocking ram so any help with timings would be greatly appreciated.

Edit - well while I was trying to edit this post I had a BSOD 124 so I had to bump qpi/vtt up one notch to 1.375

looks good so far,i tried with 10-10-10-28 timings in tri channel but i left qpi/vtt on auto just to see roughly where i was voltage wise and it used 1.5v i didnt play with it too much though,is it better than your old ram?

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 :hmph: ) 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. :thumbsup:

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

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.

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

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:blackeye:

According to that site:
[Sammelthread] Samsung Green MV-3V4G3D DDR3L-1600 CL11-11-11-28 LP (OC-Geheimtip?) (http://www.hardwareluxx.de/community/f13/samsung-green-mv-3v4g3d-ddr3l-1600-cl11-11-11-28-lp-oc-geheimtip-890763.html)

There is way more room to go.


I completely gave up on 2133 Mhz:cantfocus

I tried 2400 MHz 11-12-12-31-2T:FIREdevil ...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!

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
10-02-2013, 09:45 AM
LOL
Of course I'm scared xD Those are to be running at 1.35v:cackle:
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:blackeye:

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)
6243
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:screama:
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 !

wazza300
10-02-2013, 07:21 PM
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

Teddybehr

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) :smilies13

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:hmph:).

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 !
