Ok, forgive me but I have searched and came up with mixed results.
Does this MB work with this memory (GA-890FXA-UD5 and F3-12800CL7D-4GBRM Memory)? I have looked on the list and it is not there, but reviews say it works. I have tried to find memory on the list but not with much luck. This is my first build and I had some help, but this point was overlooked. I have time to get new stuff delivered before the kit gets to my house, but I do not want to buy more memory unless I have too.
Any help on this?
Thanks
Edit: I have read the above sticky, I will look into 1333 ram right now.
Edit 2: OCZ3P1333LV4GK <-- I have found this memory on ebuyer but it says it is for i5. I will have a 965 BE Proc. here is the link: http://www.ebuyer.com/product/173107 This is getting frustrating.

I don't know so much about the AMD platform but on the Intel side we have had quite a few issues with OCZ memory. That's not to say it doesn't work but seems to be more troublesome. As you have just mentioned you are probably better getting 1333 memory with that platform as you are limited to the safe speed that you can run it.
When looking for memory don't worry if the RAM you want isn't on Gigabyte's QVL as many aren't as long as it is shown as compatible by the memory manufaturer for use with this motherboard then it should be fine. I would advise caution when choosing though as we have an awful lot of problem on the forum through memory.
Try checking out Corsair's website list they are very good. They actualy only list 1600 memory but of course you can downspeed it and tighten the timings a little I expect.

Hi there,
I understand how frustrating looking for memory can be. Not sure of your budget but here are a few links for Memory that should be OK for you.
1333MHz RAM:

Thanks for the links. What I am going to do is try the memory that is already coming, apparently I can set it to 8-8-8-24 and it should work fine at 1600. However, I would be greatful for any information on the timings if I would go to clock my memory at 1333. If this fails then I will have to buy some of the stuff listed above.
Thanks

As a matter of interest, I am running 8GB of Corsair Dominator 1600MHz RAM which doesn't appear on the QVL for my board. I am also running a Phenom ii X6 1090t at stock. because of the issues with the AM3 Memory controller I have down clocked my RAM to 1333MHz and it works fine. The stock voltage for the RAM should be 1.65V at 1600MHz but it is quite happily running at 1.5V. I have left all the timings at the defaults set by the motherboard, a GA-790XTA-UD4.
Not sure if this helps you or not but I think all such information is good. ;)
-
Aye, any information always helps. From what I have gotten from reviews and other forums with my exact same setup is this:
CPU-NB Voltage +0.1V, set timings to 8-8-8-24
This should make things all happy inside. Find out on Tuesday when everything arrives! Thanks again.
-
Don't forget to let us know how you get on. I'll keep my fingers crossed for you!
-
Will do, I get all my components Tuesday. Just for info sake, GSkill tech has given me these rough times for 1333.
7-7-7-21, possible to go lower.
However, with the above settings for 1600 they tell me that there will be no issues. Time will tell.
Thanks.
-
I'd be a little wary about running your RAM at 1600MHz as it can cause real problems with the CPU. You would be much better off running it at 1333MHz with tighter timings which carries less of a risk for your CPU.
-
Absic is too modest but I recommend that you read his study of the problems with running 1600 memory with AMD chips before you consider doing it.

Thank you, I have read everything and that is why I have asked on the GSkill forums for timings for 1333. Their reply was:
7-7-7-21 should work fine. You can even try to lower.
The DDR3-1600 method you read is no problem for the memory controller. The voltage boost helps the CPU support DDR3-1600. Only DDR3-2000+ will seriously stress the memory controller.
Thank you

Think initially I will try 1333, then maybe go 1600 since this is my first ever build and I want stability more than speed off the bat.

The timings are fine. When you lower frequency to 1333Mhz you should be able to lower the main timings by 1. Which means that, indeed, 8-8-8 turns into 7-7-7. If you overclock your RAM you should be able to lower the timings by 1 again easily. Which would bring you to what I've done - 1333Mhz 6-6-6 timings on RAM that originally runs at 1600Mhz 8-8-8.
I don't really see how their "fix" to the memory controller is going to work, though. If anything, you're actually stressing it further as you're adding voltage to it. Unless memory controllers are a whole lot different than other PC parts then "too low" voltage won't kill them. Generally, temperature is the main reason things in a PC die. Increasing voltage obviously increases temperature.
From what I've heard stepping C3 processors ( I'm assuming yours is a C3 ) are somewhat better at handling higher memory frequency but I wouldn't tempt fate. Not too long ago we had someone start a thread here and his problem seemed a lot like blown memory controllers.
Myself, I probably have a very weak IMC ( Integrated/Internal Memory Controller ) on my C2 processor as it's not working at all when you increase the CPU-NB voltage.

I would like to say that I would agree 100% with this statement and really can't understand where the GSkill people are coming from. ??? ??? ???

Well, I do plan starting at 1333, and I now have some rough guidelines. I do have a C3 x4 965, but a lot of reviews are saying that 1600 is very possible with no problems and passing all the tests. Just to let you know, that they do have the memory controller issue documented on their forums, it is a sticky, so they are very aware of the possible problem.
-
If you are running only 2 sticks of RAM (1 in each channel) then running at 1600MHz is easier to achieve. This of course, does limit the amount of RAM that you can run. The problem isn't really whether or not you can run your RAM above 1333Mhz, it is the issue of what effect it has on the Memory Controller and AMD have stated that they do not guarantee system stability above 1333Mhz.
I have come across plenty of users who thought they could run above 1333Mhz, passed Memtest with flying colours and run other stress tests successfully, only for their CPU's to fall over and need replacing, sometimes after running happily for several weeks or even a few months.
If you are looking to improve overall system speed then you are much better off and actually safer, running your RAM at 1333MHZ and overclocking your CPU.
-
What absic said. I've been able to run my 2 sticks of RAM at 1600Mhz no problem, either. Could even overclock and it all stayed stable. It's just that, one day, you may find yourself with a machine that's not working anymore. In the end, it's up to you if you want to take the risk or not. The performance difference is really small and depends on your CPU-NB overclock, too. Wasn't worth it for me.
Remember, if your IMC fails then you'll have to replace the whole CPU.
-
Well, like I said, I initially plan 1333 first, which is why I asked for timings for that speed.
