Asus M4A78LT-M LE memory overclock help please

Greetings!

Please help me with the following;

I just got myself a decent pair of Corsair Vengence DDR3 8GB sticks at 1600MHz. My Asus M4A78LT-M LE does not post when I place those sticks in :(. I've read on this forum that it is an OC issue.

So, I've tried OC'ing in the BIOS to match what the memory is. Please see link with the images for the BIOS, memory & CPU-Z screenshots. Also included are screenshots of current memory at 1333MHz that works fine.

What I am missing? :??:

Thank you in advance.

  1. So when you say does not boot you mean load windows?
    Have you tried leaving BIOS on Auto with the sticks in?
  2. if you look at the spd there is up max to 685 and not 800 also got the same series of motherboard and other maker memory sticks and could not set to work at 1600 without bsod amd restriction on this .
  3. @rolli59: No post. So, with the new sticks I can't even get the mobo to post.

    @scout_03: I guess you are recommending that I return these sticks and just get some 1333MHz in return! Correct?
  4. Try resetting CMOS before booting with the new sticks.
  5. Do I need to set the voltage to 1.5? Or just the HT @ 1600 & MemClock @ 800 are sufficient?
  6. You should not need to mess with HT while configuring the ram. Just set the memory speed and timings and if still not working then slightly increase voltage.
  7. you do not need to send them back system wont made them work at 1600 even if you try other maker motherboard restriction with amd cpu on these board model .
  8. I do appreciate all the help guys...

    I am at my wits end on this. Please take a look at the link below.

    The Link!

    With all the correct timings, and increasing the voltage to 1.62, I still could not get the mobo to post/the memory to work.

    Am I missing something?
  9. Do they work at 1333 or everything on auto?
  10. Need some info to work with - what CPU and what particular set of DRAM - need the actual model #

    Nope, the new sticks do not work with any configuration. :pfff:

    However, when I pop-in my standard 1300 sticks, the mobo posts & Windows works. So I know the issue is with the new sticks!

    Thanks for the help.

    Please visit this link. It has actual screen-shots & pics. of all that you inquired about.

    Please let me know if you need anything else. Thanks again!
  13. Any BIOS update for your board?
    Then again did you try them one at a time, could be bad ram.
  14. Your Athlon prob can't carry 1600 sticks, try starting with 1333, 8-8-8-24, 2T and DRAM voltage a t 1.6 and give it a try

    Yes sir! Did try the sticks one at a time and no dough! :pfff:

    BIOS update? ASUS's update service is not working for me, at least not for my mobo. It just keeps connecting & disconnecting.
  16. Download and flash the BIOS outside windows. http://vip.asus.com/forum/view.aspx?id=20070215223109668&board_id=1
    Follow Tradesman advice with the speed, really they should work at 1333 if they work at all.

    ok, so I'll set the mem. speed to 667Mhz, and the respective timings you mentioned, and the voltage. But what is the setting "2T" ? :??:

    Thanks again!

    for your cpu you need the 503 bios from it memory bug correction then the 801 another memory and stability correction the last 803 for system http://www.asus.com/Motherboards/M4A78LTM_LE/#support

    No mas guys!!! :pfff:

    Here is what I tried....link

    And again, no post. I'm afraid to up the voltage higher than 1.62, just in case I end up frying my older 1333 sticks.

    A BIOS update may certainly be in order!
  21. on the qvl list the have a corsair 8 gig set at 10-10-10-27 and 1.5 volts .

    Ok, I can try that timing too. But, that's not the timing listed on the memory. Please see this.
  23. the one on the list is m1 not m2 and 10 and not 9 before the b this is a single 8 gig stick at 1600 .

    Yep, I know what you are talking about. What I have is an 8GB kit with 2x 4GB sticks.

    Forgot to mention earlier, that I have tried both the sticks & they both give me the same "no post" result.
  25. if you could try them in another system to see if they will work could be defective memory sticks .

    All the fixes are included in the latest BIOS.
  27. that true rolli59 the poster never give back the bios version he had on is system .

    That is why I posted since if misread somebody might go and flash several times.

    Guys, I have not flashed this mobo, ever. So, it still has the factory BIOS on it. I don't have a floppy on this PC. So, I just need to go the USB route. Will update & try the 1333 custom timings again & post here.

    Thanks again!

    -----------------------------------
    Next would be at 9-9-9-27, 1.6 2T 1333
  31. Guys! You rock! I updated the BIOS to 803, plugged in the sticks, set the timings manually, left the voltage to auto & BOOM! :bounce:

    It works! I'm giddy with all this RAM! :pt1cable:

    Thank you rolli59, Tradesman1, and scout_03. :ange:
  32. No worries, now you can have some fun with it ;)
  33. times to enjoy the system and keep the link handy in case you need some more on it .
  34. Great!
