F3-2133c9d-16gxh + P67A-UD7-B3 not work at 2133mhz

[lexdrake]

hi buddies

recently i buy 1 par of ram modules F3-2133c9d-16gxh but i can?t make it run at 2133Mhz, i?ve tried with alot of combination between profiles XMP, latency and voltages but they only work with:

SPD:1866
DRAM: 1.64v
performance enhance: turbo
timming: auto (9-9-9-24-1T)
connected in ddr3_1 and ddr3_3 slot as the manual say.

my cpu i7-2600k work with 40x100Mhz and my motherboard is Gigabyte GA-P67A-UD7-B3

i hope you can help me find how i can make it runs at 2133Mhz

finally in the compatibility list it say gigabyte p67a-ud7... non B3, it could this the problem??

thanks.

Check that you have the latest BIOS, enable XMP, select the 2133 profile, if still problems or you already have the latest, then post up your DRAM timings (base and advanced) along with your system voltages

[lexdrake]

i update the bios to F7 version (the latest)

if i select the 2133 profile and let the timing in auto, my pc dont start

the timings for SPD 1866 are show in the image below.


Uploaded with ImageShack.us
DRAM voltage: 1.64v best stability
VTT: default
core voltage: 1.4v

I hope this information will be useful

[lexdrake]

here more information about 2133 profile (profile 2) but with this parameters the pc dont start

[Tradesman]

Try setting tRFC to 171, tRRD 7, tWTR 8, tRTP 8, tWR 16, tFAW 27, VTT voltage 1.17 and may want to take VCCSA to 1.1

[lexdrake]

i understood all parameters less the VCCSA i don't know what parameter is it, sorry, can you explain me more about vccsa

thanks

[Tradesman]

It's the System Agent Voltage...should bt default of .925 right now

[lexdrake]

i put the values that you say to me but the pc still without turning on





i put DRAM voltaje 1,64v too but its the same the pc dont boot

[Tradesman]

Might try raising tRFC to 208

[lexdrake]

And keep all other parameters correct?

[lexdrake]

look i found this maybe can help

[Tradesman]

Yes, sorry so long, got a houseful of folks here

[lexdrake]

finaly it works, i put tRFC to 208 and work realy good, all other parameters its the same that xmp profile

[Tradesman]

Sounds like a winner!

[lexdrake]

thanks for your patient men and sorry for my bad english XD.
one last question, where i can learn more about advanced parameter of ram memories, you know what means tRFC and similars.
