MSI 785GM-E51 change memory Voltage?

post #1 of 11
Thread Starter 
Hey ya'll,

I just purchased A-DATA DDR3 1600 memory for my MSI 785GM-E51 motherboard. I was able to find the memory timing (9-9-9-24) in Bios -> Cell Menu, but I don't see where to change the voltage. On the stick, it says voltage needs to be between 1.55v - 1.78v. The generic MSI OverclockingCenter utility shows the current voltage is at 1.5v.

I'm getting random BSOD's as a result. Note that I was previously using some cheap-crap DDR3 1333 memory for about a year and a half, with no issues.

Thanks in advance!

Many people with AMD systems and this memory have gotten problems.
I don't usually suggest it.

Then again your voltage is at rated... you should be able to set the voltage & speed/timings from the BIOS; it may be in a different section.

Oh wow, I've just discovered the AMD issue with 1600 from some google-fu. Greaaaaat. Can I get away with running this memory at 1333?

Also, I found the speed timings in the BIOS, under Cell Menu. Unfortunately I can't seem to find the voltage settings in that area. Other areas in BIOS don't even have settings for Memory; at most, they show "1600". I'll keep digging...

Thanks

Edit: Blue screened after 2 hours uptime; on reboot I went through every option on the menu, and didn't find anywhere I could change voltage for the memory. Went ahead and changed from 1600 to 1333, see if that will give me more stability. At worst, I'll toss back in the old cheap crap memory.

Actually I realized you are running a C2 revision processor. You will definitely have to run at 1333 no matter what. C2 + 4 DIMMs = no 1600

ffffuuuuuuudge. Oh well; I've been running at 1333 for 2 1/2 hours now, and no BSOD.

Thanks for your help, man!

Alright what timings are you running at 1333? You should lower them to compensate, i.e. 7-7-7

Hi,

I have the same Motherboard in use with the following RAM:
http://www.gskill.com/products.php?index=239 2x4GB

I want to run them at 1333 (which is automatically adjusted) and with 7-7-7-24.
Thats because my Processor (amd athlon II x4 630) can´t handle 1600 MHz.

My problem is that i don`t know which 4 of the 12 different timings that are available are the correct ones to run them at 7-7-7-24.

I´m new to all the OC thing, so i hope you can halp me.

If you need more information just tell me :-)


ps: sorry if my english contains too many faults, its not my native language

am3 cpus can handle 1600 (c2 with 1-2 dimms or c3 with 1-4 dimms)

just bring the ram voltage up to around 1.55
and set the timings to 9-9-9-24 (cl-trcd-trp-tras the rest to auto)

Oh thank you very much, that´s what i was searching for, i couldn´t handle the 12 different timing options^^

But i have one more question, where can i adjust the voltage?

I can´t find where to do that in my Bios...


Thanks in advance!

np
ram voltage setting is on the cell menu page
near the bottom next to cpu/nb voltage
