32GB RAM in ASRock Fatal1ty Z68

I'm looking to put 32GB Ram in the ASRock Fatal1ty Z68 board, but having a lot of trouble working out weather the 8GB ram out there will actually work. I'll be using the 2600 i7 CPU. Note, I'm not going to be overclocking this, it is a virtual server, running ESX5 or HyperV.

I've noticed a number of people suggesting trouble if you dont get all your RAM togeather.

I've found:

> http://www.memorydepot.com/M393B1K70CH0-CF804.htm
> http://www.tigerdirect.com/applications/SearchTools/ite...

which wont give me a kit of 4 at all.

Even if I end up purchasing 4GB sticks, do I really need to purchase a kit of 4? or will 2 kits of 2 be ok?

yes you can put 32gb ram but why are you putting too much of ram 8gb is enough man......try to buy decent gpu if you are a gamer.

I had no issues running 4x2gb for 3 years, purchased as 2 2x2gb kits, from the same manufacturer at the same time. One kit died before the other due to OC/overvolt, but whatever.
Get kits which are the same model, don't oc, and you should be ok.

Though i guess technically it should work the same provided it is all the same spec.

Sorry guys, I'm no gamer.

I fiddle with all sorts of software packages to aid my work. So 32GB ram is for a virtual server, I'm well aware most desktop PC's wouldn't need anything like 32GB.

Thanks for the comments though.

You can buy 2 kits of 16 GB or even 4 x 8GB dimms as long as they are the same make and model , you shouldn't have any problems with the ram as long as you buy 1066 or 1333 so you don't need to overclock your motherboard.

Any suggestions on where? the few places I found dont seem to be enough for a good price/product comparison to go purchase RAM.

I have the GSkill SNIPER, 2 x 8GB RAM on my Fatal1ty Z68 and works great. I also tested the RIPJAW 2x 4GB and they worked fine as well. I don't have the model numbers handy but GSkill seem like a good brand with fatal1ty MoB.

Also ESXi have trouble with the RAID from a driver point of view, go hyperV. Also if you can afford the 32gb for your Virtual setup, Do it. 16gb is good but the more RAM the better performance I found. Just going from 8gb to 16gb made a notable difference. I have 6 Virtual desktops and can run all at once now with 1GB for a resonable performance.

Did you purchase that online? Where if so.

I ended up with purchasing 2 kits of these

G.Skill Ripjaws-X 16G Kit(8Gx2) DDR3 1333 F3-10666CL9D-16GBXL
http://gskill.com/products.php?index=480

Running in my ASRock Fatality motherboard with an i7 CPU.

They work fantastically, and I'm now running about 10VM's using Virtualbox on a linux server with phpvirtualbox. http://code.google.com/p/phpvirtualbox/

Its easy to remote administer, I have several tasks automated too. I started with ESXi free, but it didn't really peform better (perception only) and the RAID issue was a real problem (And I was too tight to shell out for a hardware RAID card). Running it on linux I can software RAID using several RAID sets in Raid 5 and Raid 1.

The only thing I'll be looking at in the future is switching to the micro motherboards and adding a PCI-x dual gigabit Intel ethernet nic, and possibly looking at using FreeNas or OpenFiler for storage of non system VM data.

Brian, thank you for the update!

For me personally, it was about a screaming fast SSD cached RAID5 array for all my VMs:
http://tinkertry.com/oczvertex4
and the ability to handle leaving ESXi 5.0 running full-time (126 watt burn overall).
http://tinkertry.com/vzilla

I also use nested Hyper-V (for learning), USB 3.0 passthrough (for peripherals), FC support (PCI adapter, for learning with external mini-SAN device), and perhaps Thunderbolt passthrough someday as well. Finally, my de-duped daily backups of a dozen PCs (3.5TB of data in all) done by my Windows Home Server, with full bare metal restore capability that I've used for 4 years now. Not something I haven't found a way to replace affordably.

Everybody's needs are different, and it's always good to see other perspectives, and I thank you for posting your update. Knowing another memory DIMM that works well with our ASRock mobo is a good thing!

Quite right, that would have been a bit faster, I mostly didn't go to those kits as they were not as available when I purchased (in Australia). They would have also been 50% more money.

I'd rather wait a couple of months and purchase a whole new system with ivy bridge etc as a second virtual server (replacing my other current vm server with only 16GB RAM).

I guess its just the line I drew in this never ending hardware rat race. :)

OK, but think about this one.

RAM is at its lowest and it will go up, since 1 major chip maker is in bankruptcy position.
