I5 2500k - Gigabyte Z68XP-UD3P Overclocking

wazza300 · 3 Jul 2013 at 11:55

Yh,I don't think llc adds anything on that board,its dvid or llc not both together

To be safe thou I'd try +0.095v and see what happens,then add more/less later

Jony27 · 3 Jul 2013 at 11:58

Yeah, BIOS U1G doesnt even have LLC option in the bios

I will try 1.6v for DRAM voltage
and up the VTT to 1.06v, thanks

Do I need to change the PLL voltage or can I just keep it at 1.8v?

wazza300 · 3 Jul 2013 at 12:07

Could try CPU pll at 1.65v

Jony27 · 3 Jul 2013 at 12:26

No luck Wazza

Just stuck 42 as the CPU frequency and left everything else, going to test stability.

wazza300 · 3 Jul 2013 at 12:27

did you try with +0.18v dvid?

Jony27 · 3 Jul 2013 at 12:29

No, I tried with MOOGLEY's settings first at 4.5GHz with +0.07 DVID, probably need to take a break from this as I have been trying to get it OC since last night.

wazza300 · 3 Jul 2013 at 12:31

ohh,i would try same settings but around +0.015v or +0.020v for 4.5ghz

the 2600k has hyperthreading so will usually need a touch more voltage

Jony27 · 3 Jul 2013 at 12:41

But wouldn't that just mean the CPU will get less voltage?
If it doesn't boot at +0.07v DVID I dont get why using a much lesser voltage will make it boot? :confused:

Sorry for the noobyness wazza

I wonder if XMP has anything to do with it?
I mean the timings are pretty high 11-11-11-30 as opposed to my last kit which were 9-9-9-24?
This is the sepcs from corsair's website

Yes your right sorry I got dvid wrong,I don't think its memory,that should run fine

You need to slowly bump up dvid starting above +0.070v

You could try 12-12-12-35 timings to see if that helps

Jony27 · 3 Jul 2013 at 13:01

Ok, will give this a few more go before heading downtown for some fresh air

Jony27 · 3 Jul 2013 at 20:53

Been testing different settings for a while now and have come to the conclusion that the cause is the XMP.
When I have xmp enabled I can't get any post at all no matter the voltage and frequency also, when I set dvid to +0.18 it gives me a vcore of 1.4 on cpuz.
When I disable xmp, I can get to windows with 4.5GHz on auto volts but not prime stable

With xmp disabled I only need +0.1 dvid to get vcore of 1.416v
Trying to find my stable overclock right now.

Jony27 · 3 Jul 2013 at 22:46

Found a "temporary" stable OC @4.5GHz with +0.025 DVID, everything else on auto and XMP disabled

Its stable on IBT Very high settings doing 5 runs, will leave it overnight with Prime95 though just to double check

Max temp on IBT is 70C with a K2, happy enough as I know games wont stress the CPU as much as Prime/IBT does.

wazza300 · 3 Jul 2013 at 23:40

What CPU load voltage for 4.5ghz?

Jony27 · 3 Jul 2013 at 23:45

1.344v

using +0.02 DVID gives me 1.344v in CPU-z under load but BSOD's after few mintues, whereas +0.025 still gives me 1.344v but is stable

wazza300 · 4 Jul 2013 at 01:08

That's same as my chip needs for 4.5ghz,for 4.6ghz tho I need above 1.4v which for me isn't worth it

uzairzaidi · 4 Jul 2013 at 11:56

I wish I could get my 3570k to those levels! I'm running it at a cool and safe 4.0Ghz

Jony27 · 4 Jul 2013 at 12:24

I had to back off my OC down to 4.4GHz with +0.005 DVID IBT Very High 10 runs stable, going to try and use negative DVID

Also using 1.7v PLL even though I dont know if this helps lower temps/increase stability

wazza300 · 4 Jul 2013 at 15:11

how come you lowered the oc?

Jony27 · 4 Jul 2013 at 15:13

Was not Prime95 stable overnight

wazza300 · 4 Jul 2013 at 15:19

did you try a touch more offset?
