Intel Burn failure

Since it failed IBT on the first pass its likely the CPU else that memory is insanely unstable which means random corruption of files.
Raising the CPU voltage, the RAM voltage and the Northbridge voltage as well as setting the timings to SPD should do the trick.
Once you are ready, try Prime95 (64-bit version, important!) just in case IBT doesn't like something and only test 3-4Gb on IBT - should save time without compromise.
Finally you should finish testing with the OCCT: Power Supply test which is basically IBT and a GPU test at the same time, its excellent for diagnosing bad power supplies.

But it failed IBT on the third pass. passed the first two. Also, it passed the OCCT CPU test.

Cold_And_Miserable · 15 Nov 2009 at 22:54

That's still really bad. Come on, raise those voltages, don't be scared!
The OCCT CPU test is made obsolete by the Linpak test

Jakstaar2007 · 15 Nov 2009 at 23:28

Surely raising the voltages will make it more unstable?
As others have said, it looks to be the RAM that is the problem, no?
I did raise the RAM voltage up to 1.9v to test it, but CPUZ still said 1.8v. I then rebooted back into the BIOS and the settings were set at 1.9v :confused:

If i can be sure that upping the voltages won't make it worse, then i will happily do it as i wanted to overclock the system. That is why i bought the new motherboard.

Jakstaar2007 · 16 Nov 2009 at 19:31

If others agree with upping the voltage a bit, what do people with this chip think i should up it to taking into consideration my set up and temps?

Cheers

Jakstaar2007 · 17 Nov 2009 at 14:38

Anybody? What voltage should i up the CPU to? And what about the RAM?

Evil-I · 17 Nov 2009 at 15:07

Maybe check your bios version is up to date?

On the memory front my OCZ needs at least 2.0v just to boot and for my 3.51Ghz overclock on my Q6600 my RAM actually needs 2.1v. Don't be scared of pushing it a little, just make sure everything is cooled well. I'd say try 1.9 or 2.0 on your ram.

Also compare the load voltages as shown by CPUZ to what you have set in bios. There can often be quite a difference! In Bios I'm giving my CPU 1.44v but thats only showing as 1.38v in CPUZ under load.

I notice that your CPU VID is showing as 1.3v yet CPUZ is reporting your CPU voltage as 1.264? Maybe try pushing a bit more voltage through your CPU as maybe the motherboard is undervolting it. You should be okay up to 1.4v with decent cooling.

Good luck,

Jakstaar2007 · 17 Nov 2009 at 15:15

Yep the BIOS is up to date.
Just bought a fan controller, so i will install that and then up the voltages in the BIOS on boot.

Any ideas why the RAM voltage didn't change in CPUZ when i changed the RAM voltage from 1.8 to 1.9? It stayed at 1.8 in CPUZ but when i restarted and checked the BIOS it had saved them and it said 1.9v :confused:

Cheers for the advice.

No idea to be honest, maybe worth googling to see if theres any other people with similar issues on that motherboard. I'd probably try upping the RAM voltage to 2v in bios and see what that end up as in CPUZ. Don't forget to check voltages in CPU-Z when CPU is under load in case its some sort of power saving feature that is turning things down when its idling.

Best,

Jakstaar2007 · 17 Nov 2009 at 15:56

OK, i am just running Prime95 to get the load up to 100%. CPUZ reads 1.248v for the CPU, but sometimes it will jump up a bit to 1.256v :confused:

Okay mate, I'd suggest upping the CPU voltage in bios to 1.3v as that is your VID (which theoretically is the default voltage for your CPU). Don't worry about voltage fluctuations at this point, that is not unusual as long as its not too big a fluctuation.

So try CPU at 1.3v and RAM at 2.0v and let us know how you get on.

Best,

Also Jack, I'm actually a little suprised you're reaching temps of 63 degrees under load on a Q6600 at stock, cooled by a true? I'd expect it to be lower?

I peak at around 65 degrees on my q6600 at 3.51Ghz and 1.44v (although both my CPU and heatsink are lapped).

Might be worth removing your heatsink and checking fitting etc. What thermal interface material are you using and how much did you apply?

E-I

Jakstaar2007 · 17 Nov 2009 at 22:58

I will do when i get some time, i expect it could do with reapplying as it took me a while to get the HS on as it is a very fiddly installation.
I am using Arctic Silver.
Also, those load temps were when my HSF was pulling air from the heatsink. I have since move the fan to the oposite side so hopefully that will take off a few degrees, but yea, i know the temps are high.

Cheers, will give it a go and let you know.

Jakstaar2007 · 17 Nov 2009 at 23:02

Also, the reason my temperatures may be a bit high is that this motherboard has a fan for the northbridge as i think it is supposed to get quite hot. This fan is removable, which i have taken advantage of as it is annoyingly loud.

Jakstaar2007 · 18 Nov 2009 at 10:06

OK, i did it this morning, CPU to 1.3v and RAM to 2v.

However, CPUZ still shows the RAM at 1.8v and the CPU under 100% load still only goes up to 1.264v

Don't know what is going on :confused:

PiKe · 18 Nov 2009 at 10:11

Doesn't IBT have a bug with the number of threads? Try setting it to 8 and run it again.

Edit: or maybe that only applies to i7 CPU's

Jakstaar2007 · 18 Nov 2009 at 10:55

Resulty using 8 threads. Bearing in mind the core voltage still saying 1.264v.

Also, CoreTemp says that the hottest it got was 58, 58, 52, 54

:confused:

cpu-z doses not show you what voltage you have set in the bios for memory, its only shows the recommended voltage and timings for jedec standards

Jakstaar2007 · 18 Nov 2009 at 11:06

How could i find the voltage i have currently set then? Also, what about the CPU voltage?

If someone has an XFX 780i motherboard and has any tips on navigating the BIOS and overclocking it please let me know, because maybe i am missing something in there.

yes cpu-z shows what is set for your cpu, would think raising the qpi/vtt voltage a little might help
