i3 2120 will it run 2133Mhz memory ?(compatibility issues)

will09 · 20 Aug 2011 at 17:50

Hey,

i'm rebuilding my current computer just been double checking that its all compatible as follows:

i3 2120 (sandy bridge)
Asrock fatal1ty Z68 pro gen3
Referance gtx 570
G.Skill RipJawsX 4GB (2x2GB) DDR3 PC3-17000C9 2133MHz
775W Thermaltake TPX-775M ThoughPower XT
2 500GB sata 2 western digital blue (Raid 0)
standard dvd/cd drive
Noble nob20A mid-tower case

The motherboard will run the 2133MHz memory,im unsure weather the i3 2120 is capable of running the memory at 2133MHz ?

also im i right in saying that the i3 2120, you cant overclock at all?

if you see anything else that could b a problem please let me know

Thanks
Will

hi there, my guess would be that it would just underclock the RAM to run at 1600mhz, as its what it says the memory controllor supports, but i could be wrong, id reccomend just getting the 1600mhz version of the RAM you have chosen (linked below).

If you have not already purchased your system yet, go with the ram below and save some money:

do you now if this memory can be found at £55 don't really have the extra money

i take it it will not run the memory at 2133MHz then, i may still buy this memory as its default is 1600MHz, you need to enable XMP to run it at the 2133MHz. the plan is to upgrade to ivy bridge when they come out or may be sandy bright-E

Thanks

why the overpriced mobo and an i3?

if you havent bought the spec in OP, i would seriously try and balance it out.
change the mobo to some thing cheaper around £130 and up the CPU to a i5 2500k

and heres 8GB of ramwhich doesnt have the crazy tall heatsinks for £48

I'm going to be upgrade to an ivy bridge and a gen3 graphics card when they come out so i want a mobo that is going to last for the next 5 years at least since is been about 5 or 6 since I last had the money to upgrade my computer.

"future proofing" as it were

thanks

You cant overclock that CPU as its not a "K" CPU, but there is a i3 2120K coming out.

Jony27 · 21 Aug 2011 at 01:52

i would just get the best components you can now, chances are you probably wont need an upgrade and could skip Ivybridge.

I've seen the PR blurbs, but do we know when? Or will they keep it hanging there as long as Bulldozer is still not out do you think?

/Edit, AHHH...

apparently false

The motherboard supports that speed,

http://www.asrock.com/mb/overview.asp?Model=Fatal1ty Z68 Professional Gen3&cat=Specifications

- Supports DDR3 2133(OC)/1866(OC)/1600/1333/1066 non-ECC, un-buffered memory

Apparently that was an error.
Although, I see no reason why they don't make one.
If they do, I'd guess around BD's launch?

They really should do it, get it out for £110-120'ish, and you got a fast chip that can OC the nutzz of it.

i know the motherboard supports the speed do you or any one else know if the i5 2500k does ?

Oh you want to know what the memory controller speed is fo these cpu's?

http://ark.intel.com/products/52210

Its 1066/1333mhz.

im confused now.......since the i3's, the i5's and the i7's all have 1066 and 1333 that would suggest that none of them can run 2133 which isnt true....

any ideas ?

thanks

Orcvader · 22 Aug 2011 at 22:40

Sandy Bridge's memory controller is only rated for 1333mhz, anything over that is considered overclocking. You can try run 2133mhz, but best to be on the safe side and go for 1600mhz. 1600mhz is considered the sweet spot anyway, looking at benchmarks due to the high timings higher speeds needs to stay stable it's not really worth it.

arr that makes sense

thanks
