AMD CPU + G.Skill DDR3-1600

[Tradesman]

Might want to check CPU for bent/broken pins....if any are bent, can generally straighten them with a couple of razor blades

[GSKILL TECH]

That's strange, as long as the memory is installed in the correct slots, it should be dual channel..

It may be a CPU problem if the number of channels change based on frequency.

Actually dual channel 667MHz is faster. So dual channel does work?

Thank you
GSKILL TECH

Dual channel only works if I set the memory frequency to 533MHz in BIOS. CPU-Z reads between 589 and 600MHz. If I set it 800MHz it will revert to single channel and CPU-Z reads it at 867MHz. I think when I overclock my CPU it also overclocks the RAM.

Lazarus65,

Did you try DDR3-1333 8-8-8-24 1.50V?

Thank you
GSKILL TECH

Yeah. So far I've tried every timing configuration I've found so far, with no luck. I am able to get 800Mhz each stick, but it will only run in single channel. Fortunately 800MHz single channel is still faster than 600MHz dual channel. I guess I'll just have to update my CPU and see if I can achieve a better timing.

If happening in a particular game, may have to do w/ the video driver, might make sure you have the latest...and if so try a beta or back off a version can normally find newest, betas and older versions of both AMD and nVidia at GURU3D.COM

Try with DRAM at 1.55 and CPU/NB at 1.25

Unfortunately, I just had another hang. No BSOD or Error Log message, just a hard freeze that I have to manually reboot. This happened in Starcraft 2 again.

Any advice?

Think 1333 is a maybe, could try adding about + 0.07 to DRAM voltage and + 0.1 to + 0.15 to CPU/NB voltage.....The CPU itself is rated up to 1066 at 1 stick per channel or 800 (it's native DRAM freq) with 4 sticks

I tried raising the DRAM voltage all the way up to 1.6 and I couldn't even boot into windows without a crash. I have it smoothly running at 600MHz. Frowny face.

I have an AMD Athlon II X2 265 overclocked to 3.66GHz. I bought the F3-12800CL9D-8GBXL kit with my ASUS M5A78L-M LX motherboard. Due to the limitations of my CPU I can't run at 1600MHz. I've tried everything but can't get them to run at anything other than single channel 800MHz. How would I set up my BIOS to run 1600MHz dual channel, or even 1333MHz dual channel without BSOD?

[Sonsum]

Thanks for your quick reply! I set it to that and we'll see if I have a hang in the next couple days!

Hello,

This forum seems very helpful, so I thought I'd ask for some help with my DDR3 1600 Ripjaws (F3-12800CL9D-8GBRL). I bought them for my first PC build in December and for the most part, I'm very happy.

Unfortunately, I have some system instability. It's odd because I can't reproduce it very well, but every couple days or so my PC will hang without a BSOD or Error Log message and need a hard reset. It seems to happen the most with YouTube videos and Starcraft 2, but has never happened in Bioshock Infinite, Tomb Raider, or Skyrim. I followed the guide here but it has not resolved the problem. Oh, my processor is a 965 BE.

Here are my settings:
Type DDR3
Size 8192 MBytes
Channels # Dual
DRAM Frequency 800.0 MHz
CAS# Latency (CL) 9 clocks
RAS# to CAS# Delay (tRCD) 9 clocks
RAS# Precharge (tRP) 9 clocks
Cycle Time (tRAS) 24 clocks
Bank Cycle Time (tRC) 33 clocks
Command Rate (CR) 2T

Also, here are my voltages and frequencies:
HT Bus Speed: 2400 MHz
NB Speed: 2400 MHz
CPU NB Voltage: 1.2 V
DRAM Voltage: 1.51 V
NB Voltage: 1.145 V
HT Voltage 1.21 V

Thank you for your help,
Scott

Think it should, yes
