Samsung 30 nm ram question

[Grevard]

I'm looking to get some ram for my new Ivy bridge build. I want to purchase the popular low profile Samsung 30 nm MV-3V4G3D/US ram, but it seems to be out of stock everywhere or insanely overpriced on some sites($100). I want 8 gigs of this ram in a 2x4 config.

My question is:
If i buy 2 sticks of ram seperately instead of one 2x4 combo is there ANY diffrence at all.

If there is no diffrence I will buy the ram like that because it is available as a 4 gig stick.
Otherwise, is there any other low profile ram that is comperable to these samsung sticks?

I wasn't aware that it came in a 4x4GB set. I've only seen it listed as 2 sticks of 4GB. Either way, it wouldn't make a difference. When I got my Mushkin Redline 2133 RAM, it came either 2 sticks or 4 sticks of 4GB, but was less expensive just to buy two packages of the 2x4GB instead of one package of 4x4GB. Years ago I remember people said its best to get 4 sticks as one set, since it would have sequential serial numbers, but these days I don't think that matters as much.

Who said anything about a 4x4?

I was in the same boat. The kits are sold out in a lot of places. But thankfully another forum member pointed out that Newegg has the single sticks available for $23.99 each. I just ordered 4 this morning. http://www.newegg.com/Product/Produc...82E16820147094

Why would anybody buy these without heat spreaders?

Sequential serial numbers never mattered. People just think computers are voodoo...

because for good ram, heat spreaders makes temps worse. heat spreaders haven't been needed since 1.8v

Yea but they look so cool guy.

 

[LagunaX]

They don't need heatspreaders - even at 1.6v under Prime they barely get warm.
I put custom made heatspreaders on mine just for looks (clear side panel).

I wrote a thread on these:
http://www.techpowerup.com/forums/showthread.php?t=159320

Last I checked they were available at Microcenter.com for $0.99 shipping.

In addition to everything that's been said here, this article pretty much sealed it for me. http://www.overclockers.co.uk/showproduct.php?prodid=BU-002-SA&groupid=701&catid=8&subcat=


- 1600MHz (7-8-8-24 1N) @ 1.40v
- 1866MHz (9-9-9-27 1N) @ 1.40v
- 2000MHz (9-10-10-28 1N) @ 1.45v
- 2133MHz (10-10-10-28 1N) @ 1.45v
- 2400MHz (11-11-11-28 2N) @ 1.50v


Not expecting the exact same numbers but should be able to get in the ballpark.

Ok so I checked and found that these ram are not on the QVL for the Asus p8z77-v.

What do you guys think about that? Should I go with some corsair or gskill instead since they are 'supported'?

QVL means nothing, you could have low voltage ram with the same chips in that Samsung ram. Just from another company.

If you just want easy XMP profile and nothing to worry about buy some cheap Gskill and be done with it.

It's 2012, RAM isn't as important as it used to be.

 

[LagunaX]

It'll run just fine.
look at post #97 here - Samsung on a similar board:

None of my 2-card RAM sets ever had sequential SN's.

I have the Samsung RAM, it's very nice... and very small. The retention clips are higher than the RAM so no problems with CPU cooler clearances.

I think you'd be OK getting individual cards (to total 2 or 4 or whatever) as long as it's the same part number/specs.

More specifically, heat spreaders haven't been necessary on consumer memory since RDRAM... where they actually spread heat from the single active chip. Yes, we have RDRAM to thank for the pointless heat spreaders on memory.

When I first saw the link's default speeds 1600 11-11-11 I was unimpressed
but those are impressive overclocks
very nice

They're just heavily loosened. Tighten them up.

FWIW I have two sets of the 8GB set. Runs fine and overclocks fine.

Where do you live OP?

I just got 4 individual sticks from Newegg today. They're running fine in a Gigabyte Z77X-UD3H board, though they defaulted to 1.5v. Those little Sammies are so cute.

Currently I got them running at 2000MHz with 1.45v @ 9-10-10-28

 

[Grevard]

Could someone perhaps go over the advantages of lower then 1.5v for ivy bridge ram. One advantage is lower temps? lower cpu temps? My main concerns are always trying to get as much speed while doing np harm to components. For this reason I am now considering 1600 mhz ram that is cas8 at 1.5v. When you overclock cpu speeds does it always up the voltage and therefore mhz of ram. If I can up both my cpu and ram with no or minimal voltage increase, that is what I want. If I dont plan on upping voltages much or at all would I be better off with some 8cas gskill ripjaw x over the samsung? They r not much more then the samsung ones. Also I should note that I will eventually want to oc as my fps goes down in games. Maybe in like 2 years.


Lots of nub questions here sorry lol. But this is the final piece of my build I need to decide on. Thank you

Why would anybody buy these without heat spreaders?

For the same reason that very, very few people actually need a 1000W PSU.

 

[drteming]

Well, the Sammies run at 1.35v so supposedly they should run cooler. That should have no effect on the CPU temperature. I can't tell the difference by touching the modules while running benchmarks as they are barely above the ambient temperature. I guess over the long run, the lower voltage parts will save on electricity, but that's negligible.

When you overclock the CPU, the RAM speed does not change, unless you change the bclk instead of the multiplier as you would in a non K CPU. With the Samsung modules, you can tighten up the timing and run cas 8 easily at 1.4 volts, which is well within specs for the RAM, and you can get pretty good OC's with looser timing at the same voltage.

The low power consumption, much less than 1W per chip, and high temperature rating, at least 85°C, make heat spreaders rarely necessary or even helpful. Heat spreaders are primarily for appealing to the ignorant and to hide the identity of the chips (or their lack of identity).

Ok, so what you are telling me is that there is really no other ram choice for someone that isnt going for like insanely high mhz. And that the samsung ram for 50 dollars is better then gskill corsair etc that costs even upwards of $100. Its almost hard to believe lol. But I going to go ahead and pick some up. I have locaed a pair from microcenters online site. Im going to order them instead.of buying the individual sticks from newegg. Even though ive heard some bad things about microcenters online site.

lol, heatspreaders

The Samsungs are awesome. I have it daily at 2133 MHz, 9-10-10 1.525V. For benching I've had it at nearly 2400 MHz, 11-12-11 1.65V. It performs great. Heatspreaders are mostly gimmicks. Highest temp I've recorded so far at chip surface was 48C.
