8GB Dimms, <=30nm, Low Profile?

post #1 of 5
Thread Starter 
I rebuilt and re-purposed an AMD system I thought was under-performing as a BOINC machine into an ESXi host with passthrough to Windows 8 for GPU/USB 3.0/onboard SATA, and a slew of other Linux OS and appliances.

Quite simply: I have run out of RAM. 16GB is not enough for what I need to run and all channels are filled with 4GB sticks. I need 8GB sticks to hit the 32GB platform max.

I would normally spring for the 30nm Samsung RAM, all my Intel systems use this with great success, but I haven't seen 8GB dimms from Samsung. I appreciate 1.35V ram, and don't see the need for massive and gaudy heat spreaders when no overclocking or overvolting is to be done. Low-er profile ram is a must as even the current RAM doesn't let the CM 212's fan sit all the way down. Samsung's ram uses a 30nm lithography, my question is: is there any ram out there that meets these criteria:

1.35V
30nm or smaller process
Low Profile
8GB dimms in Dual Channel Kits

If so, I'm sold.
If not, I'll give voltage and lithography, but not low profile and 8GB dimms.

Otherwise, I've seen these kits from Crucial:

Crucial Ballistix Sport 16GB
Crucial Ballistix Tactical 16GB

I don't believe they are 30nm, are they? What process would these be on?

Thank you for the input!

FYI, the system, as it sits waiting for SAS breakout cables (forward vs straight through fiasco), currently uses:
AMD FX-8350 @ Stock, undervolted to ~1.225V
Gigabyte 990FXA-UD3 Rev 3.0
4x4GB GSKill Sniper 1866MHz - RMAed this stuff twice now, 72 errors in memtest might work under Windows, not under ESXi
Sapphire HD 7870, with Windows 8
Sapphire HD 6850, with Ubuntu 12.04 LTS
High-Point PCI-e USB 3.0 Card, Ubuntu
CoolerMaster 212+
Seasonic X-850 Gold

PERC H310 (not sure yet how best to assign drives to guest OS(es)):
Non-raid 128GB Crucial M4 (Windows Datastore),
Non-raid 64GB Crucial C300 (Ubuntu Datastore),
RAID 1, 2x2TB WD Red (All other OS Datastore)

Onboard SATA:
1TB WD Black "FAEX"

only memory I know of that uses the 30nm is samsung. Corsair Vengeance has a 1.35v model as well as low profile heat spreaders....

Samsung uses "30nm" as an advertising gimmick where other manufacturers simply don't advertise it. Does the lithography of the ram directly correlate with the amount of ram you can fit on die or are there extenuating factors? These low profile (barely clears ram clips) sticks with 8GB on board per dimm would have a hard time fitting the dies on such a stick so neatly if they were made at 45nm or even 65nm, right? I'm not so sure, because I've seen 8GB sticks of DDR2 in servers that were older than 2007, so at best 65nm. Just a thought.

EDIT:
32GB DDR3 Dimm

I guess that thought was not well founded.
END EDIT

Samsung's "Wonder Ram" has really spoiled us. It ACTS like a more efficient, smaller process, given its overclocking pedigree, little heat, and size. I'm just looking for something similar in 8gb sticks.

Thanks for the help!

Corsair Vengeance LP will fit beneath your hyper212.
They are sold as sets, or single sticks but the 1.35v model will be hard to find. Newegg has the 1.5v models.

Heres a photo of mine, you can see the first stick is directly under the hyper212+ blademaster fan.
You just have to put the ram in first before attaching the 120mm fan.
