Help NEEDED!

[manickkoul]

hi guys so i bought a new ram stick of the same model for my pc nd well.. the proble is that even though the ram is 1600 mhz it wont work at the frequency or even close to that .. in cpu z it shows ram frequenci at 400 mhz !! now i get it that the ram is speed stepped so 400x2=800mhz which is still not close enough to 1600 mhz .. m really frustrated now as i tried to manually adjust the timings a bit but it was not as easy as i thought . so i need your help guys .. what can i do about this problem as even after a ram upgrade the app performance and boot time is still slow

Board only supports 1600 speed via overclock. You might not be able to get there based on your hardware.

DDR3-1600 is listed in the QVL for that board...

http://dlcdnet.asus.com/pub/ASUS/mb/socketAM3/M4A78LT-M_LE/AMD-DDR3-Memory-QVL.pdf

... so it should be natively supported. Assuming these are the modules you have:

... you manually adjusted the DRAM frequency to DDR3-1600, and set the timings to 9-9-9-24 at 1.50v? Or you enabled either the DDR3-1600 SPD / XMP profile (normally Profile 1)?

 

[Mr.Scott]

That's not the list they have in the manual.

 

[redduc900]

The online QVL is probably more up to date than the manual.

 

[Mr.Scott]

The online QVL is probably more up to date than the manual.

I'll have to take your word for it, because I don't know. I DO know that the OP's board isn't working with those sticks though, so........when in doubt, RTFM.

plz have a look and confirm for me that everything is fine

 

[Mr.Scott]

11-11-11-x timings are loose as a goose. Should be doing 1600 @ 9-9-9-x.

 

[manickkoul]

lol so should i go for 9-9-9-24 ? or 9-9-9-21?

 

[manickkoul]

now i dont know the names of these values but here are the values of my current timings according to my bios .....

11-11-11-28-6-39-12-5-8-1-6-1-1-160-7.8-2t

these are the timings my bios sets automatically

I would try to lower one at a time I.E.

11 to 10 on the first line if it passes and boots into windows, then try the next line down!!

11 to 10!

11 to 10!

The last one 28 to 27 then 26 till it will not boot into windows tightening Ram is about trying one digit at a time, yes its boring and long winded, but its the only way sometimes!

Good Luck.

[manickkoul]

do i need to touch the others aswell? or just the first 4 ?

 

[Ajay57]

Just the first 4 to begin with and then always test to see if you OC is still fully stable!

9-9-9-x is stock spec. If you can't just input those figures and boot, you have a problem somewhere.
