I5 2500k - Gigabyte Z68XP-UD3P Overclocking

I have added another two sticks of kingston ram today and all is fine. No cold boots and still running 4.6ghz.

Cold boot issue about 5mins ago, so it's NOT EXTREME MEMORY PROFILE X.M.P related. It's heading towards it being the bios itself F7.

MOOGLEYS · 17 Jan 2012 at 19:19

Still no issues for me using F6. Will see how it goes with the 4 sticks of ram.

Neil79 · 21 Jan 2012 at 20:39

Had two cold boots this afternoon after going away to friends over night

However

Neil, I noticed you have pll overvoltage enabled. Turn that off too. I havent had any issues with my z68 xp since i disabled the pll overvoltage and set my mem controller voltage to 1.2v. its has to bee about 3 or 4 weeks now.

Going to see if Disabling PLL over voltage helps

My 2nd board has been working fine but I try and leave it on as much as possible as I'm scared of another meltdown.

Neil79 · 22 Jan 2012 at 11:39

Went out for about 8hrs and system started up first time, lets see if this lasts and it is the pll overvoltage setting

MOOGLEYS · 22 Jan 2012 at 11:55

If I disable PLL I get a Blue screen on startup ?

Are you using Offset mode?

All I know is that the pll Overvoltage is supposed to help get that extra bit of GHZ out of a chip, for example 4.5Ghz might be ok without pll overvoltage but 4.6 you'll need it.

No blue screen on start up here, I'm probably not at the limit of my chip yet

One thing i've noticed since disabling pll overvoltage it SEEMS to have cured the cold boot issue

MOOGLEYS · 23 Jan 2012 at 21:57

My cpu/pll voltage is set to auto I think.

I'm having the exact same issue guys.

My setup:

Intel i5 2500k
8GB Crucial Ballistix Tactile Tracer (2 x 4GB)
GTX 560Ti 2048MB
XFX PRO750W

My system generally works with one stick of Ram in but as soon as I put the second ram stick in, the computer just reboots its self when getting to the "Loading operating system" part of the boot.

I'll attempt to see now if my PLL overvoltage is on or not and also to check my DRAM voltages to see if that helps. Im not holding out much hope for this board! Seems to be quite a few issues with it

MOOGLEYS · 24 Jan 2012 at 15:57

I have not had any issues at all with my second board.

So far......

did you set to xmp? with more ram and faster speed you will need more qpi/vtt voltage or if asus board more vccio voltage around the 1.1-1.15v mark and dram voltage can be between 1.5-1.6v

Tenatious · 24 Jan 2012 at 16:04

Right well just tested... added the second stick of Ram. It is already in Profile1 XMP. I disabled PLL overvoltage, changed the VTT to 1.2v and the DRAM was already at 1.6. Still rebooting as soon as it gets to "Loading operating system". Im running F5 by the way.

Just updating to 7C to see if that helps anything.

wazza300 · 24 Jan 2012 at 16:07

tested each stick one at a time? see if it passes boot screen as one stick might be faulty,you shouldnt need 1.2v with 8gb imo,it should run fine on stock 1.05 vtt,tested the other two ram slots?

what timings is that ram?

I'm running 4 sticks with 1.6v. Have you tried everything at stock but set the ram voltage to 1.6v ? F7C was awful for me I have found F6 to be the best so far but I have had one board go bang so I'm holding back on too much fiddling at the moment.

Yeah. Tried that.

I've just updated to 7C and now it wont even turn on!

Sounds like your board is just ****** I have the exact same board with 8GB Ram and haven't had any problems with it at all

wazza300 · 24 Jan 2012 at 16:11

remove mb battery for 30mins and start over,then put battery in,load optimized defaults in bios and set your bios settings then at gigabyte splash screen press and hold alt and f12 to flash back up bios chip with main bios chip version so that both bios's have same bios version then try booting with two sticks

your using vengeance ram not crucial,im using same ram vengeance but on asus board and no probs here either at stock qpi and dram voltage
