Will this memory kit work on Z68?

I recently ordered the following memory kit:

Corsair Dominator GT 8GB (2 x 4GB) DDR3 1.5V 2133 CL9 (9-11-10-27) with Airflow Fan.

I have not received the memory kit yet, but I've done some reading today, and read that it might not work on a Z68 chipset? So I took a look at Corsair website, and for some reason I can't find them anywhere on their website...

I also can't find any good info on them. All I know is that they are Dual Channel, and Dual Channel should work on Z68? I was just wondering if this memory kit is gonna work with the specified timings and speed on my Asus P8Z68-V Pro? Or are they designed for Z77 and/or X79?

Here are my PC specs:

i5 2500K 4.7 GHz 1.39V
Asus P8Z68-V Pro
Crucial m4 128 GB SSD
OCZ 700W
Mushkin 4GB 1600 CL6
Intel HD 3000 Graphics, upgrading to NVIDIA 600 series soon.

I hope you'll be able to help me as soon as possible, so I can cancel my order.

Many greetings,

2500K is rated for 1333MHz.

To run that high, u need to OC a lot.

U can make it work, but it voids the warranty when above 1333MHz.

Will work on Z68 as well.

I have mine overclocked to 4.7 GHz as I said. Is that enough?

It's rated for 2133 MHz, so why would it void the warranty when you're going above 1333 MHz?

I always though that on Sandy Bridge system, RAM is seperate from the CPU, they share the same base clock and always stays at 100?

Each RAM is different, might be close. What CPU cooler do u have? This is tall RAM stick. Make sure it fits.

Corsair H100. Fitting them is no problem at all. I can't overclock my CPU more than this by the way, as I wanna stay below 1.4V.

And why would 2133 void the warranty, it's rated at that!

The CPU warranty : )

You can surely get 2133 RAM if you want, but the small performance gain isn't worth the extra $$$.

Yeah I know it voids the CPU warranty. But I have no problems at all and I know what I'm doing.

I have my own reasons to get 2133 RAM. But my main concern was whether it would work on a Z68 chipset or not. Because the RAM is for some reason not listed on Corsair's website, and on Newegg one guy said that he couldn't run it at spec. I just have no idea for what chipset this RAM kit is designed for? Do you know?

Most DDR3 RAM runs at 1,333MHz, but overclocking high performance RAM will run at 2,133MHz.

Ramp it up incrementally, though.

If your PC boots, restart it and increase the frequency some more.

If high MHz RAM could damage the CPU, why do they sell it then?

I ask this question again now: Do you know for what chipset this Corsair kit is designed for?

For anybody, buy the protection(or not) plan for Intel and OC all u want : )

Personally, I think most HW failure will happen, when u have poor mobo, that don't have good enough power phase design.

So, when people buy lets say, 2500K+great RAM, but buy a weak $120 mobo and push the HW to the MAX, than it fails more than other, better quality mobos.
March 29, 2012 1:37:23 PM

Well, Asus P8Z68-V Pro seems like a pretty good mobo to me, and on the box it says it supports up to 2133 MHz.

And please excuse me, but I ASK ONCE AGAIN: DO YOU KNOW FOR WHAT CHIPSET THE CORSAIR DOMINATOR GT 2133 CL9 WAS DESIGNED FOR? Cuz I can't find any info the net about this. All I'm concerned about at the moment, is the COMPATIBILITY between my mobo and the Corsair RAM kit.

They make high quality RAM.

Two matched 4GB modules for use in high performance Intel Core i7, dual channel systems Outrageously fast 2133MHz performance.
March 29, 2012 2:54:06 PM

Yes but I have an i5. I just wonder IF THEY WOULD WORK in my system?

YES it should work.
Some confusion factors.
1) Using OCed ram (ie higher thant the spec 1333), you do not have to OC the CPU for SB. I use DDR3-1600 in both my I5-750, which required OCing the CPU as the bclock was required to be raised. With My I5-2500 the bclock is fixed at 100 MHz and OCing Memory is controlled by Memory Multiplier.
2) Intel spec for Dram voltage is 1.5 V ┬▒ 5 %. many early adaptors of SB moved their 1.65 V Ram over - Which does void warrenty.
A big diff between SB and prior Intel CPUs is that the memory controller is located "in the CPU", not a external memory controller. My quess as to why memory (@ 1.5 V) and >1333 also voids the warranty is that as Frequence is increase, Impeadance generally goes down and therefore the memory controller DRIVE (current) is increased. The Voltage limitation is based on the differencial between the CPU and ondie controller.

The ram should work at advertized specs, Will need to select XMP, profile 1, or manually set multiplier/cl ratings.

As nikorr indicated, if CPU dies Intel may void warrenty even if Ram is run at 1.5 V but run above the 1333. Seems they primarily ask about what Voltage the ram is run at. Then for $25 you can purchase the OC warrenty, and even if you exceeded Vcore they will ship new CPU no questions asked (one time only).

Finally I got some good answers. Thanks!

What is worrying me though, is that those set of RAM, IS NOT listed on the Corsairs website? Isn't that strange? And a guy at Newegg said that he couldn't run his RAM at spec on his Z68 mobo. And when I search on the net, I can find nowhere, what chipset this RAM kit is compatible with. Knowing that it's Dual Channel, I assume it's P67 / Z68. Or is it another chipset, like X58 or X79? I'm just worried about the compatibility between this RAM kit and my Asus P8Z68-V Pro.

I know there are other 8GB 2133 CL9 RAM kits out there, like from G.Skill for example. But I went specifically with these from Corsair, but they run at a low voltage. And I know that Intel doesn't recommend going over 1.58V for the DRAM. So that's why I went with Corsair. But I just don't know if this RAM is compatible with my mobo...

Do you know?

1) No do not find it odd that not lised on corsairs web site - Most likely they have not updated it.
2) The "one" review at newegg - Most likely is related to specific MB. 1800 and above really needs a "quality" MB to run =>1800 in a stable condition.
3) Myself, I never buy ram => 1600 unless >30 reviews and reviews are favorable.

?? did you scan the reviews @ newegg for you MB and see if anyone is running DDR3-2133.
March 29, 2012 4:00:39 PM

Well I know that my motherboard supports up to 2133 MHz, cuz that's what it says on the box, so that should be fine.

My motherboard is an Asus P8Z68-V Pro. Seems like FAIRLY high quality to me.

^ Yes I saw that and the one review was with a LOWER Quality (I Think) Asrock MB. Not I have the ASrock Extreme 4 and it is a quality MB.
