so if i try 5-5-5-18

does it have much impact on performance of the ram?

Well done mate - very nice - Was wondering what voltage you have your RAM @

Well done mate - very nice - Was wondering what voltage you have your RAM @

ram = 2.1v
vcore = 1.54
nb = 1.56
vcore offset = auto

hope it helps.

Sweet - Just plugged those straight into the p5k and orthos is GO

Once its stable I'll tighten the RAM to what you've got.. basically I have exactly the same setup except that the mobo is the p5k.

Thanks again

@devablue : out of curiosity what timings are you getting for super pi @ 1M ?

here is my super pi @1M

here is my super pi @1M

Thanks for that...

That's very interesting looks like this crappy OCZ is holding me back so I'm not really stable but @ 3.6 I get 14.062 best stable at the moment gets me 14.2.

Help : What is happening here ?

Speedstep is off...

As soon as I go over 400Mhz (ie overclocking the RAM domain) FSB I start seeing the multiplier drop to 6 when idle but returning back to the normal 8 when under load.

You can clearly see this in CPU-Z where the core speed fluctatues between 3360Mhz loaded and when stop orthos the multiplier changes to 6 and the core speed is 2520Mhz.

I must be doing a NOOB here can anyone spot it ?

snazzy_daddy requested me to post this for him:

Thats not stable, the second core failed after 18 seconds, so his 9hr prime was on one core. Unless I'm reading it wrong?

Did you also turn off C1E?

Did you also turn off C1E?

Will do - was wondering what that was for

I'm giving up on 3.6 and 3.52ghz it needs an insane amount of volts (1.56+)
I can only get 30/40 minutes of prime here

I'm backing off and priming at 3.44

whats the vcore drop like on your board, mine was bad and i would have had to use the 1.54 +100mv to get 3.6ghz but after vcore mod it's now stable at 1.54v and not using 100mv option. before the mod 3.4ghz was my stable clock without going to mad with vcore volts.

at the moment I've set [email protected] in the BIOS.

On load CPU-z reports 1.368V
Idle CPU-z reports 1.44V

So I assume vdrop is around 0.7V

Any recommendations ?

[email protected] 1.55V on northbridge and 2.2V on the RAM

thats qiute bad 0.7. you will need to put atleast 1.6v to get 3.6ghz because of vdrop but watch your temps or maybe vcore mod board

Hmmm thanks for the tip. unfortunately the next step up on the NB is 1.7 which I was trying last night without any dice

Not sure if TAT temps are correct as I am only seeing temps of stability around 50C ish - I'll give 1.7 another try.

i'm still using 1.56v on the NB, you need to raise vcore up and beyond 1.6v for 3.6ghz because of vdrop

Yeh I've just upped the NB and failed orthos after 7mins

Upped the vcore and will keep trying until I'm stable @3.44 then maybe go for 3.6 but having a read around 3.6 is not too common.

ps What is your PCI-e clocked at ?

pci-e is 100, i've not touched that yet, not sure what is does.
the only thing holding me back going above 3.6ghz is temps, cores hitting 60c under load and also would have to unlink ram and leave at 900mhz.

Well I'm backing off in a big way something is just not quiet right so I'm going for a modest silent overclock on air...

Here is what I've got



I think maybe the system temps are the issue as the CPU itself doesn't appear that hot

 

[DoubleCheese]

I make that 0.07v rather than 0.7V.
