Hi Al l,

DDR3-1333 is the next step.  Once that is stable, we can try to go towards DDR3-1600.

will not boot with them settings

 

[Jack the Newbie]

Have you manually adjusted the timings (especically the command rate)?

Did you do this?

-->

Did you clear CMOS with the main A/C power cable removed from your PSU after the update?  If you haven't, please do that next and load "Optimized Defaults" in BIOS after that.

just a flashing curser up on the l/hand top corner

 

[tworiversuk]

yes

 

[tworiversuk]

says the dram frequency is 1866mhz, the memory ratio is 7 correct ?

 

[tworiversuk]

dropped the ratio to 5 and it's booted up

 

[tworiversuk]

but it has froze ,sh8t

 

[Jack the Newbie]

What timings did you set in BIOS?

 

[tworiversuk]

2n 9 9 9 24 74 ratio 5 xmp enabled
ram now 1333
cpu 2.67ghz
seems stable

Change tRFC to 88 and go for DDR-1600.

done that and it halted on windows

Disable spread spectrum and make sure you've set DRAM voltage to 1.65V.

 

[tworiversuk]

done all that but still shows 1333, when in bios, and will not boot

 

[tworiversuk]

trying 83, boots up,and running

 

[Aaron]

Is XMP still enabled or did you disable it?

 

[tworiversuk]

xpm enabled
this is at 83 ratio
  2n  9 9 9 9 24 
spectrun disabled
1333mhz dram
267ghz cpu
