What would be the correct setting for this memory.
Thank you for your time.

SPD

@1600Mhz, 1.6v, 1T,

CL = 7
RCD = 8
RP = 7
Ras = 24

Rc = 40
Rfc = 88 (leave it auto)
Cr = 2
Rrd = 5
Wr = 12
Wtr = 6
Rtp = 6

P.S. All the voltage and frequency AUTO in the bios

It works for me. I will try some bench to see if I can do better with 1333Mhz and 6-6-6 timings.

[Lord Mirko]

Doesn`t work can any of the G.Skill admin respond to this issue.Thanks

P.S - Thank you Buzbuz93 for your help.

The sticks must be in the blue dimm slots of the board.

Try 1600Mhz at 2T with 1.65v with the timings I gave you.

I'm running those stick now at 1600mhz 7-8-7-22 34 @1.6v 1T 100% stable.

Btw, I set the NB frequency to 2200mhz with stock voltage and it improve everest memory bench by 5%

[Lord Mirko]

Didn`t work only work at 1T 7-8-7-20-30 1333 Mhz and voltage to Auto.100% stable.There are in blue slots.Any suggestions.Thanks.

um there are a couple threads with correct timings to get it at 1600.

you should've searched... http://www.gskill.us/forum/search.php?searchid=73467

my timings are:
cl - 8
trcd - 8
trp - 8
tras - 24
trc - 34
cr - 2t

my voltage is like 1.66 or something
see if that works for you.

[Buzbuz93]

Right now, I'm running with these settings

7-8-7-22-30 @ 1600Mhz with 1.6v

Phenom II X2 550 unlock to four core at 3.2Ghz with 1.25v
Northbridge at 2400Mhz
NB 1.24v
VID NB 1.25v

I can run 6-6-6-20 28 @1333Mhz but the bench are better at 1600Mhz

Next thing I will try, 9-9-9-27 as high as I can go with stock voltages!

[Lord Mirko]

7-8-7-22-30 @ 1600Mhz with 1.6v thats better scores then on the box.LOL
Do I need to up the NB for that or all setting stay the same.

I can run 6-6-6-20 28 @1333Mhz but the bench are better at 1600Mhz

How much is the differences in benches in percent.Thank you for your reply Buz.

I gonna try this setting s now.

[Buzbuz93]

Not that much, about 2-3% better with 1600Mhz over 1333Mhz.

Raising the NB by 200Mhz = +-5% more (from 2000Mhz to 2200Mhz and from 2200Mhz to 2400Mhz)

I first did my test with NB at 2000Mhz and repeat them at 2200 and 2400.

If you want, I can do a bench with your timings to see the difference.

[Lord Mirko]

Nice thanks Buz.
I have tested them at 6-6-6-20-28 1333 1.5
Now I boot into my system in 30 sec previous was 35.LOL
Thanks.

Edit:

Wow but my Mobo temperature did go up 4 C and CPU 1 C.Hmm

[Buzbuz93]

If you are affraid by the temps, slow all the things down to stock

My mobo is 36 C
My cpu is 39 C IDLE, 47 C 100%

I think below 45 C for mobo and 55 C for 100% CPU is safe.
