DDR3 1600Mhz

[m4rt3z]

Hello, I need a little help.

I have 2x2GB DDR3 1600Mhz and i am trying to get them to run at 1600Mhz but they will only run on 800Mhz. When i go into my bios and set them to anything above 800Mhz (1066, 1333 or 1600Mhz), Windows will crash on the loading screen. Is there something else i should be doing or some other bios setting i need to configure? Not sure what specs i should give but here is the main 4.

OS: Vista Ultimate (32Bit)
MoBo: MSI 785GM-E51 (MS-7596)
CPU: AMD Phenom II X4 955 Black Edition
RAM: 2x2GB Micron Tech. PC3-12800 DDR3 SDRAM UDIMM

Any and all help is very much appreciated.

See Here  for some suggested settings from OCZ...

Seems lots of others have the same issues...


BTW that board only goes up to 1333Mhz....could be why it's not working.

Windows will crash on the loading screen.

Sometimes it all depends on the motherboard. With all the different types of RAM manufactured regardless of same output, it is still on the compatibility issue. If the RAM module is capable of the said output(overclocking)but the mobo system /specs is not, then it will still cause instability that will likely lead to such behavior. In such cases DDR,2,3 will be beneficial if there is CAS,2,3(BIOS) settings for better performance.

Thanks for the replies.

Patio, My MoBo supports upto 1600(OC) (http://www.msi.com/index.php?func=prodmbspec&maincat_no=1&cat2_no=&cat3_no=&prod_no=1866). Im Not even really bothered about OC the RAM to run at 1600, if i could get the RAM to run stable at 1333Mhz id be happy.

I know the RAM isnt exactly the best make but it should still be able to achieve near what it claims it can achieve. I dont really have a clue about timings and stuff like that so maybe if i posted a CPU-Z/HWiNFO32 report one of you might know if i have setting(s) wrong or something?

Thanks again.

No.
The board goes up to 1333

Are there any voltage settings for the RAM in the BIOS? If so, then try increasing them and see if it works.

Yea there is a DRAM Voltage or Frequency, cant remember but i set it to 1.67 and it crashed then i upped it to 1.69 at 1333Mhz, no going to try for the 1600Mhz though! lol

Its been running now for about 10 mins without and crashing BSODs on anything, maybe this worked?

One more thing, will this affect my RAM in a negative way upping the voltage?

Again thanks for all the help and replies, hopefully if people are searching to configure DDR3 and find this thread it will help them too!

Ok then, after a few hours my computer crashed at 1333Mhz. I tried lowering to 1066Mhz and the same thing happened after a few hours.

Its not BSoDing, it seems to crash the onboard video or something. Not sure what it is but it makes the screen go fuzzy, kind of like a saturation effect and the whole computer freezes.

I do occasionally get a BSoD too though, seems that this computer i built just inst up to scratch or more like my building skills are not so good! lol
