Hi Guys

Ive got 8gb of OCZ DDR2 1066mhz RAM in myy PC and in BIOS it was set at 800mhz so i thought ill turn it up to 1066mhz. So went into BIOS changed the multiplyer meaning it went to 1066mhz and saved and restarted. and it went into the first BIOS page and it stopped and wouldnt do anything. Restarted and the fans lights hard drives worked but monitor wouldnt turn on mouse lights where off keyboard lights off. restarted again the same. Unplugged it for 30 seconds it went into the first BIOS page again but frooze. So turned it off took out 3 sticks leaving 1 in restarted and it worked i got into BIOS and changed it back to 800mhz then reinstalled the other 3 sticks and fine. But why wont it let me take it to 1066mhz? MOBO is .....

Do you have the cpu overclocked.?

Did you manually set the timmings and voltage of the ram aswell as the frequency.?

Ashley Williams · 5 Aug 2009 at 21:56

No CPU isnt overclcooked. No i diidnt manually change th voltage or timing. do it im new to this...Help

You do need the voltage changed, otherwise the system wont be stable. Find the settings for memory voltage, and put them to 2.1v, that should be correct.

Kennysevenfold · 5 Aug 2009 at 22:08

Yeah, manually set the voltage, timmings and Speed of the ram in the bios and see if that works.

Failing that you might have to up the Northbridge voltage a tad ~0.1/0.2V as you are using all 4 ram slots.

Ashley Williams · 5 Aug 2009 at 22:14

So voltage to 2.0 to 2.1
Freq to 1066mhz
what about timing?

Can you link us the exact ram you have?

Timmings -

CL 5-6-6-18
(CAS-TRCD-TRP-TRAS)

Leave the rest on auto

Well just turned up the voltage to 2.1v and the freq the timing seemed to be set to what you suggested. when setting the timing it i assume the 5 - 6 - 6 -18 reffers to the first 2nd 3rd and 4rd option in the list as they where set as you said. see pics below. still not workiing doing the same again...

hmmm, have a look for the northbridge voltage, try upping that by 0.1V, then 0.2 volts (no further)

And keep all the ram settings the same, they are fine.

Ashley Williams · 5 Aug 2009 at 23:29

Tried upping the north bridge voltage tried 1.16 that didnt work neither did 1.2 came up with use last good boot setup meaning it returned to 800mhz.

Hmm very weird, see if you can run just 4gig @1066

Failing that, i highly doubt you would notice the difference in 800/1066Mhz anyway, could you not just run it at 800.?

Ashley Williams · 5 Aug 2009 at 23:45

Ill leave it at 800 i know it will run with 4 gig in i just wanted to play and push it a bit.

You could try slackening the timings below stock e.g. 7-7-7-20 or 8-8-8-22 and see if you can get all 4 stick running at 1066MHz.

If it works you could then experiment with different CAS settings and try and get the settings as tight/close as possible to stock. Although - you'll notice very little 'real use' difference in the slacker timings.

Ch3m1c4L · 6 Aug 2009 at 11:33

run memtest on them individually when running them at the 1066 with the rated timing and volts. if they fail send them back under warrenty and get ones that work at the correct speeds. If they all work fine in pairs at that speed, but dont in quad, then your unlucky

Im not sure about your board specifically but that NB seems very low, im used to seeing 1.4 as standard and 1.5 if your running 4 sticks
