Samsung 2x4GB DDR3-1600 Memory Review

Samsung has sent us a 2×4 GB DDR3-1600 very low profile and low voltage memory kit to review. Samsung has been in the memory business for over 18 years and as you will see, this kit really shows their experience in the memory area.

Quick Look

Now before we move on lets take a quick look at the RAM and packaging. Remember to not judge a book by its cover.

As you can see there is nothing special about the RAM packaging and there is no fancy heat spreader to be found. Just pure unadulterated RAM. Not having heatspreaders is really not an issue since they generally give zero overclocking benefit to the end user and only adds cost to the product.

Clearance comparison to G.Skill RipjawX

Clearance comparison to G.Skill RipjawX

This is a very low profile kit of RAM. As can be seen in the above pictures there is no need to worry about clearance issues with today’s high end air coolers, since the the RAM sticks aren’t even as tall as the holding clips on the RAM slots! So if you cooler fits over empty ram slots it will fit over this RAM.

Features

  • 30 nm Manufacturing Technology
  • Very Low Profile Memory
  • Samsung genuine DRAM
  • Limited Lifetime Warranty

Test System & Methods

Hardware

  • Intel Core i7 870 @ 3800 MHz
  • Gigabyte P55A-UD4P
  • Samsung RAM 2×4 GB @ 1600 11-11-11-28-1t 1.5 V
  •  G.Skill Ripjaws 2×2 GB @ 1600 9-9-9-24-1t
  •  Overclocked Samsung RAM 2×4 GB @ 2000MHz 9-9-9-24-1t 1.55 V
  •  Corsair TX750 V2
  • Windows 7  64-bit with SP1
  • PNY GTX 580

 

Test Bench Setup

Test Bench Setup

Benchmarks

All benchmarks were run at default settings unless otherwise noted.

  • 7 Zip
  • Cinebench R10 & Cinebench R11.5
  • Super Pi 1m & 32m (run on normal priority and affinity set to core 0)
  • PiFast
  • wPrime 32m and 1024m
  • Synthetic Benchmarks – MaxxMem2 and Aida 64
Stock CPUz

Stock CPUz

7 Zip and Cinebench

7 Zip, Cinebench R10, Cinebench R11.5 Reults

7 Zip, Cinebench R10, Cinebench R11.5

Since none of the benchmarks rely very much on memory none of the result vary much from each other and all fall into the margin of error.

Super Pi & Pifast

Super Pi 1m, Super 32m, Pifast

Super Pi 1m, Super 32m, Pifast

Overall the results are exactly what you would expect to see. The results of Super Pi 1m and Pifast are varied but still fall in the margin of error. In Super Pi 32m you are able to see a nice improvement in times due to this benchmark having a strong relation to memory speed and timings. A full 13 second improvement between the stock Samsung RAM and overclocked Samsung RAM is a decent improvement given they were run at the same CPU speed.

wPrime

wPrime 32m, wPrime 1024m

wPrime 32m, wPrime 1024m

In wPrime there is once again nothing too out of the ordinary. The wPrime 32m benchmark consistently was slower with the G.Skill Ripjaws than with the lower rated stock Samsung RAM. This is hard to explain since the Ripjaw kit was a full 4% slower, which is just outside the margin of error. wPrime 1024m is the second highest memory intensive test of all the benchmarks and you can once again easily see the difference made by the faster speed and tighter timings on the overclocked Samsung RAM compared to it at stock speeds and timings.

Synthetic Benchmarks

MaxxMem 2

MaxxMem 2

MaxxMem 2 (overclocked)

MaxxMem 2 (overclocked)

There is a nice increase to be seen in MaxxMem2 by overclocking this RAM kit. 9.2 nano seconds are shaved off of the latency score and 0.97 GB/s is gained in the memory score. So for any applications that are memory intensive they will see a nice bump in performance. 

Aida 64

Aida 64

Aida 64 (overclocked)

Aida 64 (overclocked)

The Aida 64 benchmark returns similar results as MaxxMem2 showing the benefits of overclocking this RAM kit. For most user they will not see a real world performance increase from overclocking memory, but for anyone using a memory intensive program this kit deliveries in the overclocking department as has been seen and will be shown further in the next section.

Overclocking

Keep in mind this kit rated at 11-11-11-28-1t @ 1600 MHz stock.

The little kit that could!

The little kit that could!

That’s right folks! This little kit is able to not only able to post at 2400 MHz but was able to pass wPrime 1024m! This was with only 1.58 volts. I don’t know of any other kit on the market that will do those speeds with less than 1.6 volts. I went up to 1.65 volts, but this kit was still unable to pass Super Pi 32m. Regardless this is definitely an impressive result!

Conclusion

Well this kit was a definite treat to review. It surpassed all of my expectations. When I first received it I thought this was going to be a quick and easy review. I didn’t think this kit had much in the tank as far as overclocking potential due to its average speed and below average timings. Oh boy was I ever wrong! This kit was able to easily overclock and do so at low voltages compared to most of its other competition. Since most of the other kits on the market rated for 2000 MHz are 1.65 volts.

Throughout the overclocking process I kept saying “This has to be it, there is no way this kit can break 1800 MHz… 2000 MHz… 2200 MHz”. This kit did all that and more. Samsung has a real winner here especially since it is a 8 GB kit that overclocks like mad and costs only $62.49 on Newegg.ca. I would gladly recommend this kit to anyone looks for a budget ram, or mid-line benching ram. It gets an Overclocker Approved!

It is a beast kit of ram. Surpassed all of my expectations.
MattNo5ss's Avatar
For sure! Any budging on the timings at all? At any speed?

Oh, I just fixed a font issue in the AIDA paragraph that I missed
bmwbaxter's Avatar
The overclocked speed was tightened down from 11-11-11-28 to 9-9-9-24. @ 1600 it tightened down to 7-8-7-20.

Great sticks, and great review. Nice job BMW!!!!
MattNo5ss's Avatar
Wow! So, 2400MHz 9-9-9-24 benchable or validation only?
bmwbaxter's Avatar
Overclocked was 2000mhz for daily use. But the 2400mhz was benchable at 2400mhz 11-11-11-28. I didn't tighten the timings more because it required 1.6volts. Didn't want to push more without better cooling.

Wow!!! That's crazy. Nice going and great review.

Does it have a product name/number? All I can find when I google "samsung green" is what looks like the company's corporate responsibility jargon page.
bmwbaxter's Avatar
at the end of my review I posted the price with a link from newegg



this is the link


if you want a newegg.com link I can look it up for you.

with a kit at this price that clocks like that you can't go wrong.


EDIT:

here is a newegg.com link

i have dozens and dozens of these kits lying around in my repair shop. i never understood why we bought crap RAM, but from the looks of it they are amazing !
a c i d.f l y's Avatar
Correct me if I'm wrong here, but these appear to be the best dual channel price/performance and just pure performance on the market?
cold.nut's Avatar
issues i have found with them however is a lot of boards just don't like to POST with them. a lot of the DDR3 boards that come through my computer repair shop don't accept these sticks!

i don't know why.. however if you get a board that does, it looks like they are a great buy!
EarthDog's Avatar
Possibly because of the low startup voltage...?
bmwbaxter's Avatar
they are definitely up there. they may not be the absolute best performing ram but they overclock amazingly and are way cheaper then most of the other kits on the market.

have you tried upping the voltage to 1.5V? it worked fine in my test setup @ both 1.35v and 1.5V with no issue at all.
cold.nut's Avatar
yeah, more voltage didn't improve the results at all on some boards. four or five boards have come through that don't like them period!
johan851's Avatar
That makes me want to snag a pair and sell what I have, but I can't tell if you just got a lucky set or not.
BugFreak's Avatar
I'll be your huckleberry. A set is on the way and I'll post as I play with them.

Any store that sells them in Europe?
bmwbaxter's Avatar
I am not familiar with European vendors. But I would assume they carry them.
Evilsizer's Avatar
maybe i missed something, in your review you show 1.5v needed for stock speed/timings. however newegg shows 1.35v needed for stock speed/timings. running 1.6 or 1.65v for a short period of time is not going to hurt the ram. it is nice to see budget ram kicking ass agian for price/gb and for its ocing ability.
bmwbaxter's Avatar
Stock can be 1.5v or 1.35v. I currently have it running 24/7 crunching Rosetta at stock speed and timing with 1.35v. Sorry for the confusion.
Evilsizer's Avatar
yea if sammy specc'd it for 1.35v that would explain how they clock so well. it has been a while since i have seen sammy make good IC's for ocing.

thanks for the review on them, should have said that before. got caught up in the specs and make sure i was looking at the right ram on newegg. work computer blocks redirects. :X
bmwbaxter's Avatar
They are the best clocking kit of ram I have and the cheapest.
Evilsizer's Avatar
i should have asked this the first time, can you post the IC info?
bmwbaxter's Avatar
I am at work ATM I will post it when I get home.
EarthDog's Avatar
You can read what is on the IC's in a picture in the article.. at least in the featured image on the front page you can clearly read the numbers... is that what you are looking for?
bmwbaxter's Avatar
I had a picture of the IC in the review but it was removed during the editing process it seems.

but here it is.

@Mattno5ss
Can you put this in your very first post. since it will then be visible under the article on the frontpage?
BugFreak's Avatar
These remind me of the old BH-5 budget ram days. I hope they live up to it for sure.
MattNo5ss's Avatar
It only shows a link to the attachment ID number in the article comments. I can insert the full pic into the article if you want. However, I did mention what the link is in the edit to my post.

Here's how to decipher Samsung's IC model number. May or may not be useful

102449
bmwbaxter's Avatar
accorind to the JEDEC specs from CPUz these are actually rated for 1.28v @1600mhz.

102450

I am unfortunately unable to test and see if they work since 1.3v is as low as my bios goes on DRAM voltages. they did post @ 1.3v for stock speeds but I didn't test since there is no point really on undervolting your ram.
Evilsizer's Avatar
yea most of the pics i looked at in the article were to small for me to make anything out. as in the resolution was to small and some of the numbers ect were fuzzy in the image.
good to know, thanks!
mikeyw's Avatar
I can't find these for sale in the UK, searched the model number, all I get is US results.
johan851's Avatar
So any idea if you can get these ICs consistently? I want to make this a Christmas present to myself. It's basically free assuming I can sell what I have for close to what I paid, or put my memory in a new server box or something.
bmwbaxter's Avatar
I do not know if you will get these ICs. but since this is Samsung Ram and Samsung IC's I think you are likely to get the same. If you do end up buying let me know if you got the same ICs.
johan851's Avatar
I'll wait to see how it goes and then pull the trigger.
BugFreak's Avatar
They arrive on Monday. I was hoping to get them today but no luck.
Evilsizer's Avatar
if newegg pics do hold true i found my gem! as far as the IC goes they are the same but seem to have different location manufacturing, im guessing by the difference in the top and lower numbers/letters. the main thing is the K4B section, now the interesting part the pic i posted is from SO-DIMMs at the same stock speed/timings@1.35v. while it isnt that big of a deal since you cant oc laptops, it is good for smaller boards. that still have some ocing features but use so-dimms.

johan851's Avatar
Very interesting.
bmwbaxter's Avatar
very nice. are you atleast able to tighten timings with cputweaker or a program of the like?

because even at stock speeds I was able too tighten timings to 7-8-7-20-1t. but that was 1.5v I am curious as to if the so-DIMM IC's can muster any increase.
Evilsizer's Avatar
on the current sodimm's in my i3 330m, it will do 7-6-6 but i can not change first cas in cpu tweaker
BugFreak's Avatar
Everything is in and running. I have started with everything set to auto except for memory at 1.5v and 1T. It booted right up to 9,9,9,24 1T

I will be tweaking the timings and speeds for the next couple days and will post as I go so let me know some tests you guys want on them.
johan851's Avatar
You could just try the speeds and timings from the review.
BugFreak's Avatar
Sure, state the obvious why don't ya. BTW here is a shot of my chips.

EDIT 1: So far the 7,8,7,20 is not stable. I can get into Windows fine but Super PI 32m fails on the first round. I even upped them to 1.6v. 2T and 1T changed nothing as well.

EDIT 2: In an attempt to be lazy I was hoping to keep everything as my sig states and pop in the ram which has not worked. I have since put everything else to stock and so far seem to be more stable at 7,8,7,20 1T. I'll repost after I get some speeds worth posting.
johan851's Avatar
They're OOS now. Of course.
BugFreak's Avatar
Update: After setting everything back to stock I still can't get the pc stable at 7,8,7,20 T1 1600. It did pass Memtest+ at 7,8,7,20 1T 1333 all night though. So far I have tried up to 1.65v to try and get it stable but tests 4 or 5 fail every time.

My other settings are:
cpu- 2800
cpuv- 1.475v
cpu/nb- 1.25
vdda- 2.5v
nbv- 1.2
nb1.8- 1.8
htv 1.2
sbv 1.10

I realize the volts might be high for stock but they are what the pc has ran stable with sig speeds for months so I just left them as is. Let me know any thoughts or ideas on getting it stable and I'll give them a shot.

Current settings I am testing are below.
johan851's Avatar
That's disappointing. I'd be interested in the higher bandwidth tests too, since that's what SB seems to like.
bmwbaxter's Avatar
I was also running on an i7 870 that has been known to have a very stong IMC. try running a higher speed see if you can get atleast 1800mhz @ 9-9-9-24.

also is your system able to do 1600mhz @ 8-8-8-20?
BugFreak's Avatar
I was just able to get through a couple passes of Memtest at 8,8,7,24 1600 so I am going to start playing with the speed to see if I can get anything. I'm trying to keep the faith but it is fading quickly.

johan I'll try and get higher bandwidths going but this setup is only confirmed stable at 1600 and is an AMD after all. I'll repost in a bit.
BugFreak's Avatar
Well after multiple settings and tests I can't get the system stable with these sticks in. Based on the voltages above does anyone have some input on what could be changed to make it a little more stable? Otherwise I am going to call these a dud.
bmwbaxter's Avatar
Are they listed on your motherboards qualified vendors list?
johan851's Avatar
A bit of a resurrect, but I finally grabbed some of this RAM to replace my Mushkin. Most DDR3 doesn't overclock worth crap beyond its rated specs, and all I was able to do with my Mushkin was to go from 9-9-9 1T to 8-9-8 1T at 1600MHz with a voltage bump.

I've been playing with the Samsung this morning. All the dual channel kits are sold about, but I grabbed two individual 4GB sticks. I got a clean pass of Memtest86+ at 2133MHz, 10-11-10-27 1T @ 1.47v. I'm running a Prime95 blend now. Pretty awesome stuff!
