Tuning Corsair XMS3 8GB

Which particular setting???

Some settings are under the hood settings and you dont have access to these in Bios but Mem Tweak It can read em. This is often why updating bios can make a previously stable clock unstable as many memory timings the end user cannot change in the bios menu. This can also be why one board running the same frequency's on the face of it is more efficient.
 
With post #17 & #18

The settings you listed are slightly different to my BIOS settings. Are they sometimes abbreviated slightly different?

Just wondering which settings I can set in my BIOS as everytime I reboot I have to tweak them in MemTweakIt to get them tight again
 
Which settings particularly mate. Whats the name of them in MemtweakIT??

As I point out they may be under the hood stuff. Do the values correspond??

You are setting the main items. Is the clock stable???

Ok my BIOS lists them as so:

tRC -
tRRD -
tWTR -
tWR -
tWTP -
tWL -
tRFC -
tRTP -
tFAW -
tCMD -
tRW Stability -
tWR Stability -

So most line up but a few don't

tRRD 7
tRFC 296
tWR 16
tRTP 10
tFAW 30
tWTR 19
tCKE 6
tWCL 8

These that you listed, I need to match them up with the settings in my BIOS
 
I'm stable at this at the moment but would like to set the secondary values in BIOS so every time I reboot I don't have to manually set them in MemTweakIt you see



My BIOS options are posted in the pictures in post #2 if that help you list through them for me?

Thanks for your time fella
 
In the second pic down on post 2. These are the secondary timings for channel B. Under adv timing. Enter these for both channels!!!

Done.
 
Nevermind

My question wasn't how to set them, I am fully aware of how to do that, it was which settings correspond to the settings you've listed, as there are slightly different options in my bios, that's why I provided the screen shot

Think either I'm not explaining it very well or you're missing the point
 
Mem tweak it is a Prog designed for ASUS MB. It has settings that even with ASUS are not available to be tweaked under bios by the End user. Gigabyte Bios has differing settings to ASUS. If its not obvious how the settings translate across then often they dont.
 
Ok that's all well and good

So ignoring MemTweakIt and Asus settings

Could you please look at my bios settings and suggest which secondary timings Isshould slacken off to reach higher frequency and in which order should I tighten them to find the tightest setting for each?

Hope that makes sense, very hard to convey sometimes through text
 
Higher Frequency try 2T. After that dont bother as your so slack already bandwidth will; suffer.

Tuning down work on them in the order here:



You dont have the setting leave as is.
 
Ok thanks

Do the settings have to be any certain numbers to tie in with other settings or just keep dropping them until it becomes unstable?

How do you set these in MemTweakIt but test stability in Memtest, or would they have to be set in BIOS I'm guessing?

Thanks
 
Yeah good improvment!!!

The new dimms you are getting are Samsung IC so tune fairly well.

Focus first on TRFC 128,121,114,107 or 96.

Then working down mem tweak it aim for 6 TRFC as low as possible, AUTO,10,6,26,6,5,7 to help gain stability back out the two third timings settings that are currently at 4 to 5 clocks.
 
Like this you mean?

What about DRAM refresh interval. does that change auto?

Yep spot on!!!!!!

Now work on TRFC 121, 114,107 or 96. Then work on the values that are 6 in the secondarys down to 5.
