Honestly, it's confusing the crap out of me...

of course i want to be future-proofed, but i've heard that there are issues with DDR3 ram running at 1333 on certain AM3 mobos, so...

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

i don't know if i should trust the newegg reviews, like for example:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

the ram looks good, but the reviews are like "Waaaah, won't work on my Asus deluxe, blah blah..."
So, will THIS ram work on my giga mobo?

what should i get? i want price to be under $110 and either of 4x2gig or bigger.

oh wait, can you run DDR3 1333 at 1066?

First thing is what mobo are you using?

The best RAM is g.skill and OCZ IMO

Some mobo's can downclock the RAM, but why buy the faster RAM if your board can't support it?

um, the name of the mobo is my topic, but anyway...
It says it can do DDR3 1333 and 1066, but i heard there are issues with running DDR3 1333 on AM3 mobos, so...

can you suggest one off the Egg?

i just wanted a RAM than you can just plug in, without dealing with the bull$hit of manually setting timings and voltages, so, is there one?

my fault, didn't notice the board in the topic.

some boards natively downclock the RAM to boot.
I would recommend these for your board. You will want to run cpu-z and check the bios to make sure it is running at 1333Mhz. The same issue exits on intel boards. Sometimes you just have to adjust the settings.

ahhh... Perfect! for once they mentioned my board for this ram, thanks. Hell, i don't even care if it actually runs at 1066, i just want a no-bull$hit ram. this is good!

OCZ has become top notch in memory. Although as I mentioned, you should check to verify that it's running at 1333. It's not too hard to bump it up in the BIOS.

With the Gigabyte mobo's you should be able to run 1600mhz as well since they max out at 1666, also the AM3 cpu's memory controller is set to 1333, the I7's is 1066, by that logic it'll take higher Ram speeds than I7, the 790 chipset just holds it back so you can only run upto 1666.
February 22, 2009 7:05:28 AM

ah i see... i'll just bump it up then.
February 22, 2009 7:19:03 AM

Just check you get the one's with the lowest latencies unless they're like $50 more or makes it out of your budget.
February 22, 2009 7:24:45 AM

meh, i got a $1000 budget, can't go any higher with the ram in prices.

also make sure you get the 1.8/1.9volt stuff, 1.65v is for the I7 MBs
February 22, 2009 7:57:47 AM

ok, but if even then, will 1.65 work on my giga mobo?

The ocz listed above is 1.75v, but yes, it will work.

OCZ and mushkin make god memory.

mushkin - 9-9-9-24
vs
OCZ - 6-6-6-20

I'd pay the extra to get the OCZ
February 22, 2009 10:03:35 PM

ok... i know a bit about computers, but NOT that much...

how much of a difference is there in timing on rams? like, 9-9-9-24 to 6-6-6-20?
care to explain?

The latency is how many clock cycles it takes to receive the data on a chip's column. The less clock cycles it takes, the better.

The same RAM would work....
However, in all honesty, you won't see that much of a performance boost with the DDR3. The only reason I purchased it was b/c I got a deal I couldn't refuse.

I would recommend this board and RAM:
board:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
RAM: ocz reaper
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
or g.skill pi black
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The ocz reapers are a little cheaper w/ the rebate. The cas timings are much better w/ the DDR2 memory. They are also much cheaper.

I've got the Gigabyte GA-MA790XT-UD4P in the mail (to go with a Phenom II X3 720) but am similarly confused about what RAM to get, since the ones Gigabyte suggests for this board range from 1.5V to 1.9V - what's the difference?

The Kingston HyperX memory on that list, for instance, is a 1.9V module. Does this mean I could use ANY 1.9V? I'm interested in 2x 2 GB OCZ DDR3 PC3-12800 Platinum Edition (OCZ3P16004GK), CL7-6-6-24, 1.9V. Will it work?

That RAM is a little high in voltage. The higher the voltage, the more likely you will have to do some tweaking in the BIOS to get it stable. I would recommend these

You should start your own thread though.
