$48.99 Samsung 30nm DDR3 1600 hitting 2133?!?

1,575V, I dont have the low voltage parts though, mine are specified to run at 1,5V with 1,575V max iirc.

Edit: They are the same chips though, just different ram boards.

I had to drop to 1600 and up HT, you are already doing that, Mathragh?

Anyway, no performance differences, just greater capacity either way.

These sticks are so like the old UTT Winbond chips of years ago...:laugh:
 
I didnt even try with 2 sticks only, I had 4 sticks from the beginning, and they worked perfectly for me.

But anyway, I didnt have such issues. I'm running on 2560NB and 2560HT. I did need to up the CPU NB voltage to 1,32V though. According to some guides up to 1,35V on the CPU NB was fine so I thought it was ok.
 
Hey cadaveca,

I think I am already running the ram at 1600, upped by fsb (240) to 1920, just looked at cpu-z, and the fsb:ram ratio says 1:4, that means I am running it at 1600 right?

Considering that I am already running it at 1600 (if I am), do you think I will be able to hold 4 sticks at 1920 @ 1.47v?

I was following your review when I was overclocking and I don't want to go above the recommended 1.47v for the 1.35 parts.

Huh. good info, still. I am using Crosshair 5 Formula and 8150, so i thought we'd get similar results. 2 sticks clock great for me. Perhaps I'll spend some more time tweaking.

:rockout:

CH5 latest BIOS has memory profile for 4 GB sticks...that profile sets 1.4 V on NB.:eek: I was kinda shocked at that, but AMD chips aren't ones that I am afraid to shove volts into if needed. I am not using that profile, however. I did up to 1.35 V as well. I've not spent too much time with the 8150 yet, been kinda busy with other hardwares.
 
Okay, well, I can post some pictures of AMD overdrive showing all the sub timing when I come home in 1 hour, might help you both clock your ram with bulldozer.
I've spent considerable time getting them to run above 2100MHz aswell, but no matter what timing or subtimings I used, they wouldn't be stable in prime95(would boot in windows fine). Even upping the voltage to 1,65V wouldn't help. The only thing I didn't try was setting it to T2. After that I gave up and set most of the subtimings to auto again and settled for my current speed/timings.

BIG EDIT:
ok, got some screenies from settings I use:
AMD Overdrive memory timings and configuration. This seems to correctly display *most* of the timings.

Wow, I should have gotten an Asus board instead of an Asrock one, so much more options/control!

Thanks for the info, I think I will grab another 2x4gb of the Samsung ram and see what I can do with it, hopefully it will hold the same speed while maintaining a low voltage.

Okay! I hope it all works out for you:) just remember that I dont have the low voltage parts when you're setting up your voltage!

Good luck!

Would you recommend usong AMD overdrice over the BIOS to someone who doesn't fully get/have the patience for BIOS overclocking?

That depends, for an instance, as you can see you cannot change the Cas Latency in overdrive. This is one of the most important timings of your RAM, so thats something you would still have to do in bios. Furthermore, you cannot change the Ram:FSB ratio in overdrive, meaning you are limited to FSB overclocking your RAM only with overdrive.
However, I can imagine AMD Overdrive actually giving you more RAM tweaking options when it comes to subtimings if you do not have a very expensive and/or overclocking friendly board.

Also, I noticed that if I changed any voltage in my bios from auto to a specific manual voltage, it would not display this voltage correctly in Overdrive(This could be a motherboard specific problem though)

I would certainly recommend using AMD overdrive for finetuning your RAM frequency however.

Also, AMD overdrive is great for tuning your processor, especially if you got a multiplier unlocked processor. In combination with a good stress test which reports errors before you actually bluescreen, you can really finetune your frecuency/voltage without the hassle of rebooting all the time.

Have two more sticks here to try out as well and thus can also test 16GB (and also a buddy's Sandy build to try them in).

Hi Wrigleyvillain

Did you ever get a chance to try this out? I am tempted to go to 16gb while RAM is cheap - at this price for this performance I can always use the ram in another system in future or something.

Also, in general, I noticed BF3 yesterday felt smoother/more responsive on the new mem. This was updated gfx drivers too though so that might be a factor. Not sure if this was because of 1T timings or 1600>2133 mhz or both. Nice though!
 
this is probably a dumb question seeing as how these are dual-channel kits, but has anyone tried these on x79?

No not as yet will tonight. I have to send the other two sticks to El Mayo in the UK soon anyway.
 
When it comes to memory, X79 is currently king of the crowd. Although the AMD APUs clock ram well too, X79 has both speed, and performance.
 
Depends on the chip for sure, but agree.

Wait until IB comes out and its IMC makes SBe its whipping boy. ;)
 
IVB won't have the bus flexibility of SNB-E. I kinda wish it did though.:laugh:

though IVBe is right around the corner, and one would assume IVBe will be to IVB what SBe is to SB currently.
 
One would assume... sure. Point is, IB's memory controller is more robust that SBe. When IBe comes out, then that conversation is relevant. ;)
 
wow. these are silicon GOLD!
i was semi-impressed on my p55 boards... but now, on this x79, just wow.
i'll post screenshots later as i'm at work now, but they're running stable at 2235MHz, 11-11-11-28-143 1t at 1.395v measured with a DMM under full load(1.4000 in BIOS).
can't wait to get home and push them further :D
suffice it to say, if anyone sees date code 1149, BUY THEM.:rockout:
