For those of you who don't know, there is a particular ram kit that seems to be loved by those who want a lot of performance on a budget. I am of course talking about the samsung low profile 1600mhz memory (http://www.newegg.com/Product/Product.aspx?Item=N82E16820147096). One might look upon the specs and notice that they are rather poor. However, there is a catch. The low voltage of the ram give you plenty of overclocking head room, and the 30nm ram manufacturing process that samsung uses allows for some pretty amazing overclocks such as this one.



For a while OCN has had a long discussion about the wonderment of this ram through this thread here http://www.overclock.net/t/1210482/samsung-2x4gb-low-voltage-ddr3-1600-kit-ocing-to-2400-discussion , but I think it is time that the samsung memory gets its own club.

To submit your memory overclock, please take a screen shot with your OCN name somewhere on the page, CPU-Z showing your memory settings, and show that prime 95 has been running for 4 hours on blend. I would also like it if you can run a maxmemm benchmark and post your submitted score.

Alternatively, you can also run Intel burn test on max settings for 10 passes. It will take up a lot less of your time.

For those of you who don't know, overclocking can sometimes come down to winning what is known as the silicon lottery. The idea is that no two computer parts are exactly the same. These little differnces can have a major effect on how a particular hardware bit will overclock. You can have something that overclocks extremely well, or something that can barely even run at the advertised specifications. This applies to CPUs, GPUs, Ram, and other things. Rest assured, Samsung has done a fantastic job is making memory that can pretty much get a great overclock almost all of the time. But sometimes there will be a one in a million part that will overclock so well that it becomes worth it's weight in gold. Getting your hands on a one in a million part is just plain dumb luck, but what if we could improve those chances for you?

When companies make parts, and in this case ram, they produce their parts in batches. Let's say we have two batches, "batch 1" and "batch 2". While one stick of ram from batch 1 might overclock slightly different than another ram stick, but they will be somewhat similar. On the other hand, if you have a stick of ram from batch 1 and another stick of ram from batch 2, their overclocking potential will generally be completely unrelated to one and other.

That is where you, the member, can help out fellow members. If you have something that is really spectacular, show us the batch number by taking a picture of it and uploading it to this thread like so.


I will put it in the google docs spread sheet, for all to see.

For those of you who are searching for some good overclocking memory, you can go to a microcenter, or some other store that sells this ram and try to match the batch numbers to better your odds at winning the silicon lottery yourself.

Happy Cherry Picking and good luck to those who seek to win the silicon lottery

Samsung memory is not limited to low profile green ram. It can take on many different forms, and can sometimes perform a lot better than the basic cheap low profile ram we all know and love.

Samsung has two types of memory chips. One is called HKY0 which is used for the low profile ram, and the other is HCH9 which is used in all sorts of other ram.

If you know/think your ram has samsung memory chips, please upload a picture along with your OCN name on the page and any CPU-Z screen shots that have to do with your memory. Please double check and make sure that when you take your screen shot that CPU-Z mentions the part number. That way I can try to make a link under the google docs spread sheet (sheet number: HCH9). If you are feeling generous, please link me a page to where you bought the ram from. It would help out a lot.

Notes: I would like to add a list of places where you can buy this ram from other countries. I know that often times this stuff may be hard to find or locate in other parts of the world, and I would like some of our international OCNers to provide me links so that I can add them to the list.

I forgot about linX, but I have never used it before, so I am not sure if what you are showing of proof that it is stable. I personally know it is stable, but when I add your overclock, I want to make it so that people who are thinking about buying this ram will know for sure that these overclocks are 100% stable.

That being the case, let me ask you. How much time on linX would be enough to prove that the ram overclock is rock solid, while at the same time being short enough where it wouldn't be too much of hassle to a person who wants to join. If you can do that for me, then I will be happy to add that rule as a secondary option to prime 95.

Why not title the thread Samsung Green Memory Club, the actual product name? It could get confusing for people who aren't familiar with this product when everyone refers to it as a different noun, Wonder RAM, Miracle Memory, etc, will probably get more Google hits too. I guess it's still obvious since it's Samsungs only line of RAM, but yeah, just saying.

I've been using the DDR2 version for like 5 years now and it's served me very well, the Samsung DDR3 is high on my list for ram choices when I finally upgrade cpu/motherboard lol. On that note, does anyone know if a normal waterblock would fit on this RAM?

Because it't true name is samsung (product number here). To me that is boring. So I went with the OCN name for it.

At the stock 1600MHz speed of the memory, whats the lowest voltage you guys are getting? I just got this memory along with a new Z77 ITX board. So I'm really working on getting my rig as efficient as possible. I don't see a huge need to overclock the memory since I'm pretty casual now, just enjoying the mini-ITX and some occasional gaming... my board on boot set the ram at 1.575V which I saw that and went nuts! I've got it at 1.370V right now and wondering how much lower I can go...possibly <1.350V?

Stock timings, lowered my voltage to 1.360V and my internet didn't work...so weird. Whatever I did, couldn't get internet....had to keep it at 1.370V..no issues...weird

Try to run prime 95 in blend test to see if your ram is stable at the specified settings. If it isn't, then I would run memtest 86 off a boot disk with one stick of ram at a time. One of them will probably shoot some errors at you, and I would simply RMA that back to samsung.

Count me in. Currently running it only slightly overclocked at 1702 8-9-8-14.

I was running this at 2000mhz 9-10-9-20 before, but when I raised BCLK to bring my CPU from 4.5 to 4.6 (which raised memory frequency to ~2046) it didn't play nice any more and I wasn't able to get it stable with voltage increases on DRAM/VTT/VCCSA. My chip doesn't seem to have the greatest IMC. It doesn't seem to have too much effect on my maxxmem scores any way.

1702 8-9-8-14


2000 9-10-9-20


Just a sidenote, 4 hours of prime95 hardly indicate stability

, only a test that runs at boot can really tell if a system is stable or not. To illustrate: at one point I was able to pass 24 hours of prime 95 custom blend (90% memory usage), get 30 full memory passes of IBT, 750% coverage in HCI memtest in windows, plus a ton of hours running games and hyperpi/wprime/various other benchmarks. Sounds pretty solid right? Yet when I ran the bootable version of HCI it returned errors before it even reached 1% coverage.

Forgot to mention, I got this at salland.eu. At the time I ordered them this was the only place that shipped them here, I don't know if any other webstores that ship here carry them by now. Unfortunately they're also a lot more expensive than in the us. Anyway, here's the product page.

Lol, I had the exact opposite happen. I can get 2400mhz at 10-11-11-28 -1T run just fine for 24 hours in memtest 86, and as soon as I ran blend on prime (no CPU OC mind you) it crashed immediately and gave me a memory error as the cause.

Hey thanks, anything that can help. I hate it when I have to spend hours searching for sites for non us citizens to buy this ram, so I can only assume how others must feel.

Side note: What voltage are you running your 1700mhz OC at? I would like to add it for those who might be curious.

Right now DRAM voltage is at 1.41, but I'm still tweaking my settings so I reckon this will be lower once I'm done. I only lowered it a bit when I went from 2000 mhz to 1700 mhz, I'm still trying to find the lowest timings I can get away with and after that I'll try lowering voltages further.
My final (lowest stable) voltages for 2000 mhz were ~1.12 VCCSA, ~1.063 VTT and ~1.47 DRAM (they never stay at exactly the same value, for some reason my motherboard likes to add 10-20 mv to every voltage except vcore).

lol, I guess we can't escape from running a multitude of programs when tweaking anything.
