Memory for AMD chipsets

post #1 of 10
Thread Starter 
Hi, I am curious as to what memory is good for AMD.
Most places say designed for Intel.
I am also looking to upgrade my brothers memory.

Some information:
My system currently:
8150fx CPU
990fx sabertooth motherboard
Sapphire Radeon HD 6990 GPU
Have a 2TB 6gb/s HHD
120gb sata 3 ocz agility SSD
1300w coolermaster silent pro PSU
(GPU and CPU are connected via EKwaterblocks, so i have a lanings D5 pump, 360 radiator, and a reservoir)
Coolermaster Half X case.

Currently i have 2 4gb x 2 (total of 16 gb) duel channel crossair dominators 9-9-9-24 1600mhz
They do not run at that.


My brothers setup that I build is about to change
He is looking at the GA-990FXA-UD7 gigabyte Motherboard.
Has a 1100t cpu
6970 GPU
SSD and HHD inside also.
Currently he has a crosshair IV motherboard
Currently he has G skill 9-9-9-24 1600Mhz 4x4 kit (intel i believe)



So my question is: Does AMD support two duel channel kits? (My memory is on the qualified vendors list fort hat specific motherboard)
If so how hard would tweaking those be to get the desired results?

Currently my Memeory is not even sitting at 1.65V as advertised. it seems like only 1 stick is working propperly.

Would appreciate any help

Pretty much any DDR3 will work in AMD. Just set timings and voltage if necessary

It's never recommended to mix DDR3 RAM because often they will not function without errors. Any of the name brand RAM suppliers offer RAM approved for AMD Phenom II CPUs. This is what I would recommend as it has been tested and confirmed to work with AMD CPUs. Not all DDR3 RAM works on AMD CPUs without issues.

When you fill all DIMM slots some mobos default to a lower RAM frequency because it's more difficult for the IMC to work with four DIMMs. In addition the latencies and frequency for a PAIR of DIMMs bought as one, matched kit is not the same when you install TWO of those kits instead of ONE matched, 4 DIMM RAM kit.

At the give-a-way prices on RAM at the moment, I recommend buying ONE matched, tested, RAM Kit of the full qualtity that you need if upgrading, instead of trying to make two RAM kits function properly when they may not.

Get 1600-cl9: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007611%2050001028&IsNodeId=1&name=AMD

They have performance kits in the way, but it will be more money, in my opinion it's not worth to pay extra for it, you can tweak from cl9.

AMD has issues supporting more than 2 DIMMs at spec clock. I would suggest 4GB x2 is plenty for good experience.

To clarify, their motherboard chipsets have issues supporting more than 2 DIMMs at spec clocks.

You shouldn't have any problem on Phenom II x6 or AMD FX processors running 4 DIMMs at DDR3-1600, pending possible need for CPU-NB voltage increases of course.

Hey guys, so I am getting this
468
Everything is at default settings.
However... this is what it also shows:
356


I have the UEFI bios, and have very little clue as how to change the timings of the memory.
But as far as I know, they should not be dropping like that should they?

With CPU-Z you look at the Memory tab to see how the RAM is running at the moment. The SPD tab shows other options that the RAM can be run at, NOT what the RAM is currently running at. You're currently running at 802.7 MHz. x 2 = 1605 MHz. , i.e. "~1600".

Under the max bandwidth it says that it is 533Mhz though.

It's just reading the default RAM SPD settings, not the actual operating frequency/bandwidth.
