True enough but I find Windows testing more telling for instability, LinX with the All Memory option is particularly good for stressing the memory and memory controller.

Dual / quad channel is simply multiples of 2 / 4, tri channel is multiples of 3.
Buy 3 packs and you have 24 Gb in Tri channel for X58, or 2 packs and use 3 modules.
Just note that most ram struggles to reach 2000 Mhz on X58 due to the CPU integrated memory controller.

ok thanks guys
think im going to go with a 16gb kit, use 12gb on x58 and save the last stick for an upgrade

Got the same for my X79 RE build but thought they would look better in satin red (flash washes out the colour a bit)
Hi guys,
Just got my Samsung Green RAM, 4GB. Installed and works great with my 2500K.
Upped the speed to 2133MHz (10-10-10-28 1N) @ 1.45v as shown on the OCUK product page. All benches run great, and stable in prime for ages. But noticed that a few of my games started to crash with APPCRASH error, Exception Code:c0000005.
This happened in RO2, and Shogun 2. Seeing as i have only changed the RAM, is this the probable culprit?
I have upped the voltage to 1.55, but have not had time to play games to check. Is it likely that the RAM is causing these crashes?
And is 1.45v a little low for 2133MHz (10-10-10-28 1N)?
Thanks for the help

mem test the sticks first and run IBT one pass only max mem. If this is stable and crashes are only during games I would suggest upping VCCIO a touch to give the memory controller a nudge which it often needs maybe alos look at 1.5v for the memory.
Do you mean 4gb or 2x 4gb ????

Thanks for your reply 8 pack.
It is 2X4 gb.
Well my system wasnt IBT stable at max setting, and what a effort to get it stable!
So now i have the RAM the same, with 1.55v (i set 1.5 in the bios but HW monitor shows 1.55)
However to get stable i had to increase my vcore to 1.4 (CPU 4.6ghz), underload HW monitor read this as 1.37.
My core temps are max 83, with package temp max 87! Too much?
I was running with a vcore of 1.36 for ages and had no probs until i tried this ram, still, happy its 100% stable

After some advice - just been suggested to put my Samsung Green RAM at 1.65V to achieve 1866MHz on 9-9-10-28 (2). Thought I'd ask here as I remember reading >1.5V was not good?
I have an i7 3770K OC'd to 4.4GHz with 16Gb Green RAM

You shouldn't need as much as 1.65v to achieve just 1866MHz. I have 1.62v to achieve 2000MHz at 8,9,9,21 1T or 2333MHz at 10,10,10,28 1T
If Ivy then 1.65v will be fine.

Cheers Rossi~ It is Ivy Bridge so do you think I should try the timings you suggested and your voltage or are the timings and voltage specific to individual systems?
One other thing, this 1T etc, in my BIOS I don't get the option to select a letter.... why is this? Does it matter?

I would say definitely try, in fact because you're on Ivy, you have a better IMC so should try for the golden 2400MHz. Don't go working on what voltage and settings i've used for 2000MHz though, you have a different CPU and probably a different batch of RAM as well so the results will vary.
1T / 2T is the Command Rate setting. It's probably just got a few selections like 1, 2, 3 and Auto. 1 is preferred for latency but as you get into higher frequencies you may need to relax it to 2 for stability.

Cheers for that. Being a novice I'm not really sure what timings to enter other than random!
Where is a good place to start testing other than looking at what others have done?

2133MHz seems to be the best place to start. With timings of 11,11,11,24,1T @ 1.55v.
Once confirmed stable via memtest/IBT on maximum, you can either tighten the timings or push for 2400MHz.
If you go back over this thread you can get a rough idea of what to expect but you will still have to run tests and tweak it to suit your setup.

thanks mate. I'll get cracking

No dont use the same settings as Rossi, he is on X79 your on Ivy Z77???. What board you using ?? with Ivy 2400 is easy although it depends on the motherboard.
OcUK Staff
You obviously upped the speed / amount of the ram when you added the green which stresses the CPU more so may well need more Vcore to get it stable or to relax timings. If its 87 under IBT I would not worry as you will never get near this in every day use.

8 Pack - I have an Asus P8Z77 V MB with an 17 3770K.
If you have any advice I'd much appreciate it. I tried Rossi's suggestion of 11,11,11,24,1T @ 1.55v but don't think it worked. After rebooting the PC stayed hanging for about 30 seconds, had to hit the reset button a couple of times to reboot. I can only assume this was down to instability?
So I changed back to the original suggestion made to me for 1866MHz of 9-9-10-28 [email protected], but made the mistake of entering 9-9-10-24 2 @1.65v. Ran memtest and it passed.
I have no idea what the difference between my mistake and intention was other than it worked!
Advice appreciated - Really think I should do some hardcore reading on this subject as going in blind could be a bit dumb.....
Soldato
If it didn't work then up the voltage to 1.6v and try again. It's just a matter of finding the right settings for your setup. Generally 2133MHz 11,11,11,24,1T is easy to achieve.
