Hey guys, I just wanted to ask if a RAM clocked at 1600Mhz stock would work on a Motherboard that only supports 1333/1066Mhz frequencies. The guy at the shop I'm buying it from said that it will so I just wanted to make sure, Thanks.

Yes, usually when ram is rated say at "1600mhz" it can easily "down clock" to 1333Mhz/1066Mhz.

The real question is does your motherboard support the ram? For example if you have a DDR3 motherboard, DDR2 will not work. There is also sometimes issues with certain brands not working with specific motherboards.

Mostly yes, but you need post the MOBO is question.

Voltage is one of the big 'mostly' (most DDR3 will run DDR3-1333 @ 1.50v) followed by Density and then some kits simply are bad or incompatible.

Q - What MOBO?
Q - What CPU?
Q - What RAM?

My bad I thought it was a simple Q/A :p  , here:

-Motherboard: ASUS P8H61-M LX (REV 3.0) http://www.newegg.com/Product/Product.aspx?Item=N82E168...

-CPU: Intel Core i5 2500 (non K)

-RAM: Kingston HyperX Blu 4GB http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Be careful. Sandy Bridge's recommended RAM Voltage is 1.5V. Not sure why you want this memory, but try to find one with 1.5V.

He doesn´t want it, the retailer is the one who wants to sell that thing.

^+1; in fact I think voltages over 1.65 are specifically disavowed (may damage the memory controller), and that RAM needs 1.7V to run at its advertised speed. The latter illustrates another variety of marketing dishonesty. Most RAM will run at a faster speed if you give it more voltage, but that doesn't mean it should be rated for that speed.
In fact, if you want your system to love you long time, look at some of the G.Skill low voltage kits; mine is running at DDR3-1600 on 1.35V.

With that ram i'm kind of worried for you - it says it requires 1.7-1.9v to operate, and some motherboards don't like out of spec ram, especially if the DIMM slots provide 1.5v.

I just checked your motherboard manual and it states that your ram is not in the list, so I would be leery of getting that ram. It may work, but do you want to take the chance?

I would reccomend this as per your manual (page 1-15):

Kingston KVR1333D3N9/4G

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

4GB ram, 1333mhz rated speed. And it's compatible with your motherboard to boot!

The 1600Mhz had a deal on it, but since It's not advised I'll just spend the extra couple bucks on a 1333Mhz 1.5v RAM, Thanks!

No G.Skill available for me here, I'll just grab another kingston hyperX 1333Mhz rated @ 1.5v, thanks for the info!

buy one of those it's our own choice both are good and overclock to 1600mhz

Crucial is fine, they are one of the few that actually produces their own IC's vs slapping IC's on a PCB.

Do you recommend it over the Hyperx? I don't mind spending the extra money but if the difference is too minimal I rather just put that 5 euros towards another 4G dimm.

Kingston also is one of the few that makes their own IC's, but it all depends on which HyperX model the voltages vary from model to model.

On LGA 1155 only P67 or Z68 can OC and can run RAM >DDR3-1333.

Both the Kingston HyperX Blu and Crucial you linked would be much better IF they were in a KIT of 2X2GB or 2X4GB, but both will work and run the same speed (performance is the same). The metal 'wrapper' on DDR3-1333 isn't needed it just for eye-candy.

Is buying 2 separate RAMs (same model of course) considered a kit? or do they have to be in the same packaging? Because I can't find a 2x4GB kit for the cheap Crucial ram, Cheers!

No, it's a pseudo Kit and often XMP fails even with 2 sticks and is guaranteed to fail with 4 stick; XMP shouldn't be used with any more than the 1 kit or 1 stick.

See if this Crucial kit 2x4GB is available cheaply = CT2KIT51264BD1339

XMP?! And nope, no Kit for Crucial Memory available for me, will this be good enough?:

Agreed the KVR1333D3N9K2/8G is a good choice :)

No not me, pick jaquith if you ever pick someone. Haha he stuck with you the whole thread.

Forum admin give jaquith the best answer if you see this.!

Funny thing though - the threads title is "Quick question!" and this is somewhat of a longer post than I thought it would be :p

Haha, I thought it was a yes/no kind of question xD .. Anyway as i said i can't select the best answer, the button is no where to be found -_- and yeah I was gonna give it to @jaquith but oh well, maybe a mod can do it.

Apparently this was set up as a Discussion.

Yeah, 99% of 'Quick Questions' aren't as simple as they seem to be. ;) 

Good Luck!!!
