So I have a xfx 790i ultra motherboard and a QX9770 CPU...I have 2x2GB DDR3 2000mhz of ram and it runs fine...I added 2x2GB of DDR3 1600mhz ram and set the BIOS to DDR3 1600 with 9-9-9-27 2T timing for a total of 8GB (4x4GB) both sets are Patriot memory

I ran a bunch of stress tests and it all passed...then I rebooted and got one long beep...then the ram reverted to DDR3 1067mhz with 7-7-7-20 1T timing. Is this really that bad though?

So what would be best for gaming? 8GB of DDR3 1067mhz with 7-7-7-20 1T timing or 4GB DDR3 2000mhz with 9-9-9-24 2T timing?

Your cpu is plenty fast enough, regardless of how fast the ram is.
Slower ram may look bad in synthetic benchmarks, but there is little difference in real application performance or FPS. I think the number is 1-3%.

Gaming performance is almost totally dependent on the graphics card anyway.

More than 4gb of ram won't help games much, unless you are also multitasking. Here is a study from Corsair:

Considering that you already own the extra ram, I think you should use it.

4GB DDR3 2000mhz with 9-9-9-24 2T timing better than DDR3 1067mhz with 7-7-7-20 1T,
U can Set in BIOS CAS & Timming 4GB DDR3 2000mhz with 9-9-9-24 to ratio 3:8 7-7-7-20 1T get clock 850 (OC 4Ghz CPU)

1T : best performance
2T : best Stabillity

Go with 8GB over 4 because although it may not affect your fps, it WILL affect your gaming experience, for the better.


Go ahead and read the article about RAM on the front page of www.tomshardware.com

Yeah, I read the article on Tom's front page too...although they don't really address my issue of such different clocks and timing. If it was just between 4GB at 2000mhz and 8GB at 1600, I would choose the 8GB. But the difference between 2000mhz and 1067mhz is pretty extreme.

Henydiah: I'm not following you on the over clock advice. What do you mean "ratio 3"? And get clock to 850? Upping the fsb to 425? That would put the memory at 1700mhz...are you thinking that would be better that fsb at 400 and memory at 2000? Plus that would limit me again to 4GB.

Sorry missing !
clock 850 looked from CPU-Z 850x2=1700 ram same u want !
850 very easy to get it, u can Oc again your RAM untill 900 maybe 1000
