Ram for new build advice needed

ickymay · 28 Sep 2012 at 21:01

hiya all new to the forums and hitting the ground running :cool:

I am building an i7 system with the Intel Core i7-3820 3.6GHz LGA2011 10MB 130W and the Intel® Desktop Board DX79SI.

Looking through the QVL i don't see anything in 4gb or 8gb Ram that i can source so wondered how good a match the GeIL EVO Leggera 32GB (4x8GB) DDR3 PC3-14900C10 1866MHz Quad Channel Kit (GEL332GB1866C10QC) would be for my setup or if anyone had any experience with this ram

any helpful comments appreciated

Many of us have memory thats not on the motherboard QVL that run without any problems.

If you are truly worried then pick from the list.

Unless you have a real use for 32gb of ram you would be better off with 16gb which for most uses is plenty. Using 16gb or less also makes ocing easier and puts less stress on the IMC.

thanks for the comments so far guys, when you say less stress do you mean overhead ?

I am mostly concerned that I want to buy the ram for this system then use it and forget it with the minimum of overclocking involved.

If you have a use for 32gb of ram its not a problem with minimum ocing.

90% of users will never need that much though, you are just paying out for something you will not use.

The IMC is part of the CPU, when you get into heavy overclocking going for high memory and high CPU speeds this all puts stress on the CPU. Also having a larger ammount of memory installed gives the IMC in the CPU even more work to do.

Very sound advice thank you

My only doubt now is I wonder when 32gb will be needed and become the norm ?

my experience with Ram is you need to buy it all at the same time so the component quality and build is the same as that varies with the price of metal at the time.

By IMC do you mean the MCH = Memory Controller Hub ?

What i found for i7 Architecture was;-
Acronyms
CPU Central Processing Unit
DMI Direct Media Interface
FSB Front Side Bus
ICH Input / Output Control Hub
IOH Input / Output Hub
MCH Memory Controller Hub
SCH System Controller Hub
QPI Quick Path Interconnect

IMC = integrated memory controller

thanks for making that clear :cool:

I reckon following your advice I will go with 16gb ram , my one question is would I be better with two x 8gb sticks or four x 4gb sticks ?

As I understand it I lose stability for every slot I fill so two x 8gb sticks would be more stable ?

favouring these GeIL EVO Leggera 16GB (2x8GB) DDR3 PC3-19200C11 2400MHz Dual Channel Kit (GEL316GB2400C11ADC) [GEL316GB2400C11ADC]

4 x 4gb is better on an x79 mobo that way you get the maximum bandwidth.

8 Pack · 30 Sep 2012 at 21:52

Get 4 x4gb Hynix based 2133mhz DIMMS kit. This offers the best bandwidth while not limiting overclock and is easily enough capacity too.

Not sure why you got that board over many offerings from ASUS etc.. which almost certainly will clock better and tune memory better too.

8 Pack, how do you know whats Hynix based?

ickymay · 1 Oct 2012 at 01:05

not impressed with hynix , i would prefer GeIL, what about using GeIL EVO Veloce Hot-Rod Red 16GB (4x4GB) DDR3 PC3-14900C10 1866MHz Quad Channel Kit (GEV316GB1866C10QC)

Interestingly enough GeIL support recommend ;- GeIL Enhance Corsa 16GB (4x4GB) DDR3 PC3-12800C9 1600MHz Quad Channel Kit (GEC316GB1600C9QC)
