Ultra low profile 1.35v 30nm DDR3 capable of 2400MHz. Perfect for SFF builds.

I don't have "The knowledge" for good procedure on this but I found by trial and error and reading some that these will run tRAS= CL + tRCD + 2. tRRD will probably go quite low (even as far as 4). tFAW = 4 * tRRD.

Try these 1 Step at a time though because I may be mis-remembering settings from other speeds

I think that I had no bandwidth increases below tRFC of 128

I wish I had some screen shots but I'm running some other tests for the next week.

Just have a play with it then run AIDA64 Cache and ram bench then play some more.

If you just cannot get it stable try enable PLL overvoltage because I am thinking that the threshold at which this kicks in automatically might be a little high.

I had success in stabilising by taking vccio up too but that was definitely when trying for 2133 9,10,10

Hope something here helps.

thanks buddy for the help, for ex my patriots 2000 9-11-9-27 1T are tRFC 171 and they are stable at same timmings same volts at 2200, but the samsungs even tough they go to 2400 or more at 11-11-11-28 1T at 1,58125 with VCCSA 0.98125 and vtt 1,08125 they are stable i can play but once passed memtest 200% in win then not again its weird, i remember having this problem with the dang ballistix

with the patriots i have to put manual 171 if i dont it dont boot, so i was looking to increase tRFC on the samsungs

will give a try

thanks a lot

what voltages are ok 24/7 please ? am I ok up to 1.55V ? (3770K/Ivybridge) I'm running a Gene V

I find 2200 11-11-11-28 2T nice and easy at 1.44V (16gb)

2200 10-10-10-24 seems ok at 1.48V or so

it seems to struggle with 2400 - can't get that stable - even at higher volts. and 1T seems ok - but hard to get stable - I had 2000 CAS10 1T running fine at 1.5V - with a slight bump in mem controller volts on 3770k, but then i got a blue screen during a handbrake encode - after 30 hrs of encoding .... (was a memory error too) - so I've gone back to 2T

I guess 2200 CAS10 at 2T is as good if not better than 2000 CAS10 at 1T ?

[OldChap]

I decided that 1.58v should be OK and have run it at that for a couple of weeks 24/7 crunching Seems good.

1T should give you better bandwidth but you need to run Cache and Mem bench to test these then Memtest the final settings for some hours

The pcb gets warm at 1.6v and hot at 1.65v. You need some airflow aimed at the sticks at higher volts. The pcb these are on is simply not designed for higher voltages, the chips will take it fine though.

I wouldnt run over 1.6v without airflow and 1.65v with airflow 24/7. Benching youll be fine up to about 1.75v where they stop scaling (again airflow required).

[aussie-revhead]

Guys, what are these sticks capable of on x79?

[OldChap]

PiLsY; Do you know if they keep scaling if you can keep them cold?

hey aussie

check X79 thread OC nub tried them and they do awesome

yes at 1,65 they get a bit warm i have a fan above then and they do well

Awesome, thank you.

Do you have a link to the x79 thread? I did search for it earlier and it didnt show up ....

[AVulgarPicture]

is new egg still sold out on these dimms?
pete you make sure you tell me before you go ordering any of these, i want at least one kit.

[PiLsY]

PiLsY; Do you know if they keep scaling if you can keep them cold?

Certainly over 1.75v does nothing for me on air, though they dont actually get worse until 1.85v (which may mean some headroom with DI/LN2).

Thought I'd mention there's a second source for these in the UK for anyone looking:
http://www.yoyotech.co.uk/item-detai...cts_id=4377589
Personally I don't rate them very high as a place to buy from, but if all you're after is the RAM might be ok.

Little bit cheaper than OverclockersUK. Thought it was a bit rich that OCUK's email today advertises them as "Overclockers UK EXCLUSIVE"...

Price difference here is still quite high though:
Yoyotech: £49.82 incl. VAT
OverclockersUK: £53.99 incl. VAT

NewEgg: US$47.99 / 1.55 (rough exch. rate) * 1.2 (VAT) = £37.15 incl. VAT

Here is my result with these sticks on the Asus P8Z77-I Deluxe (ITX-board). Sadly it isn't possible to raise the VCCIO-voltage.
But i think DDR3-2200 on an ITX-Board with only 1,395V VDimm is a nice result.

2200MHz | 10-11-11-25-1T | 1.395v | 8GB | Z77 | Prime95 | Screen

That little mobo recently caught my attention but this is just awesome! Who would say it has so much potential...

[eva2000]

Been ages since I oc'd memory, but thought I'd start with some of these Samsung 30nm modules and very surprised at what they can do even on Z68

System used:

• Core i7 2700K 3126C256
• Corsair H50-1 H20 cooling
• Asus Maxmus IV Gene-Z 3305 bios
• 2x 4GB Samsung DDR3-1600 MV-3V4G3D/US 30nm
• Sapphire HD5870 flashed to Asus bios
• 80GB Intel X25-M SSD
• 1200W Silverstone OP1200

DDR3-2133Mhz 10-10-10-24 1T at 1.35v !



DDR3-2161Mhz 10-10-10-24 1T at 1.35v

[AVulgarPicture]

George! put them on Z77 and make them sing!

[eva2000]

no Z77 as yet heh

DDR3-2176Mhz 10-10-10-24 1T at 1.35v



DDR3-2245Mhz 10-10-10-24 1T at 1.40v



DDR3-2257Mhz 10-10-10-24 1T at 1.425v

zzz eva
you can do that 9-9-9 too, just increase the voltage a little

[nksharp]

Can't find any of these in Canada still. May have to order one from the US if I can't soon.

So many people in Canada have no idea about Newegg's Canada site...'

[nksharp]

I did, just was never in stock when I last looked. I had it auto notified but never got an email :/

$10 shipping on ram is a bit to much though, now I remember why I usually don't order from newegg.

When it comes to these memory modules, what's better, running them at 1866 with timings 9-9-9-24 1T or 2133 with 9-10-10-27 1T? I got a 2500k running on an Asus P8P67 Deluxe @ 4.8GHz. What kind of program can I use to see the difference while benching them? Thanks on advanced and sorry for the noob questions.

Rule of thumb is to run the highest OC per cas over standard as possible. The standards are 100Mhz per cas, so cas 8 = 800Mhz(1600Mhz), cas 9 = 900Mhz(1800Mhz,) cas 10 = 1000Mhz(2000Mhz), etc....
Plus Ivy likes speed over timings, so just try for highest speed, then tighten from there.

I use Aida64 to see the memory bandwidth using their Tools>memory and cache benchmark feature
