I know the 12v rail is fine, it was the 3.3 and 5v i was concerned about mate. And also im just trying to find out why the hell i cant get the pc stable at a higher oc...

3v
5v
nothing to worry about.

Who has actually broke 4.4 ghz with these chips yet ?

Ive been at 4.5GHz for quite a while now. Could probably go a tiny bit more.

What vCore do you need for 4.5GHz?

PCIE Frequnecy: 101 (set this when playing with 210+ bclk) - Not broke, aint fixing it.

I have my bclk at 218 without changing the PCIE frequency, so if I set it at 101 what I am going to gain?

 

[Ste]

Nothing. For some reason 101 helped with stability

As Ste says, if you are stable at 218 then pcie set at 101 won't do anything for you.

I set it to 101 whilst finding my max stable bclk which topped out at 222. The PCIE can help stability at high bclk settings.

my plan today is to try and get cpu offset voltage sorted and to test pcie to see if there is any benefit at my current OC.

Just stumbled on this thread ... I currently run a X58A-UD3R rev 2.0 FH BIOS with i7 930 CPU usually on stock or with a mid OC to 3.33Ghz , if i can get a X5675 CPU would i notice any difference overall i.e in games / general performance?

Obviously im assuming it will be cooler , 130W vs 95W.

 

[Ste]

I'm hoping with a 5670 I can stick with the 200 bclk I know is stable from my 920 and use x21 or x22 as able to work on 4.2 or 4.4. Assume that works?

 

[Ste]

I'd get the most out of your existing CPU first. Should be a noticeable difference between 3.3 and 4.0

Cant just reboot at the moment but its around 1.39. CPUz is reporting it as 1.384v

 

[ALXAndy]

All I am going to say is...

I hope they're right!

I run Realtemp GT. Download Realtemp and in there is a exe called RealtempGT. It gives all six core readouts.

Eeee this little bugger is clearly quite fond of voltage. Just had a quick play and it won't even play nicely with those sorts of volts at 4.5ghz with HT off.

I use Realtemp also Andy, that was more to see what other power was being used elsewhere etc.

I think my 4.3 is my CPU's sweet spot, which is more than enough for my day to day potterings.

4.3 is actually right up there. These CPUs are not Sandys remember !

 

[sports_brah]

Still running mine at stock.

That's very true. Have happily settled at 4.3ghz now have it running stable with all 12gb of ram. Can get it stable at 4.4ghz but it actually performs slightly worse than at 4.3ghz and needs voltage upto 1.408v.

How sure are we that qpi limit is 1.4v as a thread on overclock.net seems to suggest 1.35v as absolute limit.

 

[ALXAndy]

I think tbh if you stuff a CPU full of volts performance decreases.

I've seen it myself.. In fact if I over volt my 3970x it bsods lol.

 

[Mr. May]

Okay spent the evening overclocking my new 5670

So far got it stable @4.4ghz
22x200 with ram at 2000mhz vcore @1.344v but set to 1.35 in bios but.......

As soon as I move the blck up it will make my ram unstable stepping over the rated 2000mhz

I'm just to stuborn to run them @ 1600mhz so.........

I think I've hit my ceiling unless I drop a multi and boost up the blck any ideas ?

 

[Batfink1892]

I think I can now declare myself truely happy with the results of all my tinkering this week.

I doubt very much I will be able to squeeze much more out of this, so I am just going to get on with doing what it was bought to do.

Very nicely done ill see if I can match that as I have a very similar system

The intel spec sheet I linked from xtremesystems states 1.4v, can't really get more official than that.
