Memory Compatibility with CPU LGA count

Hello,

I have an Asus P6T motherboard, which is a 1366 LGA configuration:
http://www.asus.com/Motherboard/P6T/#specifications

I'd like to upgrade my memory to this:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

On the bottom of the newegg page they say
"Compatible with Intel LGA1155/LGA1156 and AMD AM3/Llano/AM3+ platforms"

I wasn't aware that there's a compatibility issue between different memories and LGAs. Is this just a warning or should I actually get something else?


Also, I'm currently packing 3x2GB (667Mhz) Kingston sticks, and I heard this chipset likes 3 sticks set. Will an upgrade to 2 higher-speed dimms do me good? Or should I find a 3-stick set?

Thanks
Nitay

thats not quite the right link you got there. your motherboard:
http://www.asus.com/Motherboard/P6T/#specifications
is compatible with ddr3 rams, provided they run at the specified speeds, which they do according to the list. if there are issues with the timings not being set automatically you can always set it manually in bios.

Hello,

I've edited my post for clarity - The link I have there is the link to the memory I'd like to buy, where it says compatible with LGA1155/LGA1156

Is there a reason this memory stick wouldn't work with an LGA1366 board?

Thanks
Nitay

Your motherboard doesnot support 8gB sticks.
But it is not true that the memory will not work with lga1366 boards, for example it will run on a ASUS rampage III as it supports 8gB sticks.
Lga1366 has triple channel so it is better you install either 6 cards or 3 cards. The cards doesnot need to be of a particular set as sets of 3 cards are rare these days. So multiple individual cards and make sure that all cards have same specs, nothing should be different if you want to avoid crashes.

Thanks for your reply.

How could you tell that my motherboard doesn't support 8GB sticks?

Thanks

The maximum supported ram by your motherboard is 24gB and you have six slots, so if you divide 24 by 6 you get four, also it should be stated on the product page.

Okay, so what are my options?

Can I get a pair and a seperate one? like these:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Or need I get 3 identical sticks?
I thought about getting 3 of those:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Do i need sticks on multiplies of 3? Can I stay with the 3xGB I have now and just get another one or two?

Sorry for so many questions

Thanks
Nitay

i doubt this is true. the maximum is there because the northbridge does not provide addresses for spaces on the ram modules should you go over the limit. there should be no problem with assigning addresses on the same DIMM provided they do not go over 24gb each.

Nitay, you will not see huge performance improvements beyond using 2 channels. so stay with 2 sticks unless you absolutely need more total ram, then go with 3 or four of the same

I tried using 8gB cards on my motherboard, three 8gB cards and it worked but it caused numerous crashes and BSODs. I also doublechecked that every settings are set properly in bios. So it is better to stick to the specified motherboard ram sizes.

you can get 3 pairs of the first set you specified do not go for one set of two cards and one individual card.
Also I think that you can get corsair vengeance cheaper than the cards you specified. http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Note: When I bought my cards, six 4gB cards(individual cards) I previously called the web shop I was buying from asking that every ram modules will have same frequency, timings, voltage and version. After I got that the positive reply I went and bought them.

Set of 3 cards
http://www.newegg.com/Product/Product.aspx?Item=N82E168... $80
http://www.newegg.com/Product/Product.aspx?Item=N82E168... $100

In Israel.
There are several webshops around (although none as big as Newegg) but I couldn't find the exact models - These were quite hard to find as well

You better go with the g.skill 1600MHz set as you are getting it in a set.
1600MHzwill be better then 1333MHz as the timings are the same.
