Samsung 30nm DDR3 Results and Discussion

Guys, having read many results online (mostly on XS) I thought it would be a good time to try some and report my findings. If anyone else wants to bring some results to the table please do. It seems that the 40nm clock pretty well too so feel free to post up if you have these too.

I bought 4x4GB sticks of Samsung 30nm HCH0 rams, these are new gen like the low profile ones (HYK0) but on a normal size PCB.

I am testing these on my x79 rig (i7 3930K C2 , Asus Rampage 4 Formula), I would really like to test these again on z77 as the results will certainly be even better. So, this is what I have:

These are rated at 1333 mhz, my objective is to see if I can run them at 2400mhz and at what settings. My results are as follows:

First boot was successful at 2400-10-12-12-28-1T 1.65v, it was stable enough to use but not 32m stable so Im working on that first.

Second boot I tried 2400-11-12-12-31-1T 1.65v, then trimmed tRAS down to 28 and 1.60v and its 32m stable at that, but I want to try again for c9.

As shown here, for the disbelievers (I wanted to see it for real too), this is 1333mhz ram running at 2400mhz. So far Im pretty happy, specially since the four sticks cost $98 off ebay

More to come.



Edit:

A bit more fiddling and these are now passing 32m at 2400-10-12-12-28-1T 1.60v

They passed 12 thread wprime 1024 at these settings and are currently priming, I'm happy with that for now.

 

nice results Aussie

These stick look like they are the goods.

 

They do alot more on z77 too, x79 cant get that high.

 

This thread makes me feel really awesome having paid $360 for these

But lame cpu IMC topping out at:


But sweet results man

 

Ive been looking at these, what sort of results are they getting on Z77 aussie?

 

Since these are "cheapies" they arent binned, I know a guy that bought 16 sticks to bin, but good ones are going over 2900 !!!! Definately worth a try.

 

is ebay the only place to get these sticks? or can you buy it retail in Aus? if so where and how much?

 

No retail at the moment. Either eBay or BH Photo&Video. There's already been a thread or two about these sticks, but no other results posted before.

 

It doesnt seem that Samsung's low end rams are sold here, so yes ebay is probably the easiest source.

sammy, link the other threads to this one if you like, I havent seen any here yet. Then again they have no results so dont worry ...

 

This was the thread. Not much in there, just discussing where it can be bought from. Would like to see more results in this thread as well. I'll be testing them out when I finish my mITX build in a few weeks and see what I can hit as well

 

Ah yes I saw that one just before I started this, and yes I wanted some real results too.

This has been priming for four hours now, Im happy.

 

Wow those are some crazy clocks from seemingly bargain basement sticks. Have you tried pushing them further or is 2400MHz the highest you can get with this set?

 

X79 wont get much higher unless the IMC is very good, but mine isnt. I have not tested higher, Im aiming for stable 2400 first, I will test higher later.

 

C2 bin chips imc are pretty shithouse

 

Really? If anyone with a C1 gets a set of these please post up results.

 

I know Phil is using a set on his mITX setup over in this thread

His thread says he's getting 1866 9-9-9-24-1T. Might be worth have a look

 

hey, if someone wants to send a set to me, i'll compare them to my Trident X which are the same chips with binning and heatsinks.

 

It's good to hear. I once bought "cheapo" A-DATA RAM. After quick research it was basically there Vitesta without the fancy heatsinks. Was so stoked as I paid so little for them and got great performance out of them.

 

Aussie, can you point me in the right direction to buy a pair (or two) of these bad boys?

Want to see how much my z77 can push them to.

 

Heya Guys,
I too have a set, obtained from Sam earlier-they are going pretty well, and I would expect pretty decent results out of them, probably all capable of 2400 on good timings, on a decent board.

Without effort, I pushed 2200 on a silly mini-itx board, at low voltages - can run a few additional tests if you want, but Aussie's results should be fairly indicative of what's achievable with them.
