Z68 Extreme4 Gen3

ok i've got 4.6 stable in IBT with:

multiplier at 46
turbo power limits 200, 200
additional turbo voltage +0.055
CPU PLL Voltage 1.750v
vcore mode to auto
LLC level to 4.

it gives me 1.31v in IBT

is it better to use the additional turbo voltage instead of the offset?

also why on asrock boards the LLC level are backwards? e.g level 1 is the highest, level 5 is the lowest..

Well my motherboard has died on me this morning, tried everything but still can't get it to boot.

Board is powering on, but no display and showing error code 69 on mb.

Anyone seen this problem before?

Board was bought 14th October, as it's over 28 days old does that mean I have to rma it to asrock rather than OCUK?

Status code 69 is "North Bridge DXE initialization is started", whatever that means.

Within the first 12 months you should send it back to OcUK for an RMA if faulty.

Have you tried stripping it down to the bare essentials?

Processor, 1 stick of RAM, remove the graphics cards and use the onboard GPU, remove the sound card, just the boot drive connected.

Thanks for the reply. Yes, tried all that plus cleared CMOS.

Read on another thread that OCUK will send it back to asrock if older than 28 days and I will be without a mb for a month+. Is that right?
 
OcUK will likely send it back to ASRock and I suppose it takes as long as it takes.

It might be quicker to send it directly to ASRock but it's probaby easier to send the board back to OcUK rather than ASRock who I think are based in the Netherlands.

Guess I better order a replacement and sell the rma replacement when I get it, as I don't fancy being without a pc for that long.

Cheers.
 
Just remember that if you RMA it you only send the motherboard back.

Keep all the accessories, cables etc. as the replacement you get may just be the board only.

Also make sure you remove your processor and fit the protective plastic cover over the CPU socket.

Take a few detailed pictures of the pins in the CPU socket so that if any damaged pins are "found" you don't get blamed for them.

Thanks for the info, have ordered another from a competitor who will deliver tomorrow for free.
 
Why do people say to put ram to XMP profile? From what I can see my AUTO mode sets the same timings. Also, XMP mode sets the DRAM voltage to 1.65v when the ram I am using for this build should be 1.5v. So I have set it to auto and set the dram manually to 1.5v and 1600mhz as it defaulted to 1333. Does XMP offer anything else?

Otherwise I set to the auto overclock 4.6ghz and it seems stable. Vcore never goes above 1.35v ish and temps never exceed 72 on Intel burn test with the Gelid Performance cooler.
 
Cheers.
So for some reason Prime Blend seems to give higher temps than Intel Burn Test for me. I think it might have been because I hadn't set the threads to 8 instead of Auto. I tried this the first few times and it complained something about ram. But just tried again and it is running so I will check temps.

I noticed prime blend got temps to 75c max on a Gelid GX7 cooler. So I have changed from 4.6ghz down to 4.4ghz auto profile now and will check temps. Haven't had one crash throughout the whole time configuring this machine for a friend. Board and BIOS seem stable and really nice.
 
Just checked CPUZ again and my vcore was reporting 1.36 to 1.38vcore. Seems to have jumped up considerably from when i last checked?

Have gone into the bios and now set the 4.6ghz profile but with a manual vcore of 1.32. Just running prime now for the last 25 mins and the vcore is 1.20 -1.208 under full load :D With a maximum cpu temp of 58c.

If that stays like that ill be made up :)
 
anyone know whats these readings are? when under load they go to 74c+

i've tried google it and some people think they dummy readings

Loaded the 4.6ghz profile and changed the ram to XMP

What are OK temps?

With the

Cooler Master Hyper TX3 Evo the temps crept up to 80c :(

Prime 95 small FFT

Blend was 72c

Whats a max 24/7 temp?

intel and ocuk say keep temps below 70c,

***OVERCLOCKING GUIDELINES***

- Do not exceed 1.425v core voltage, doing so could limit lifespan of the CPU
- Aim to keep temperatures below 70c underload if at all possible
- Do not overclock with BCLK, again doing so could limit lifespan of the CPU
- Recommended memory voltage is 1.50v, so make sure to run your memory at 1.50v, higher than 1.60v could limit lifespan of the CPU
- These recommendations come from OcUK and Intel, your warranty is un-affected but we highly recommend you adhere to the above to make sure your CPU lifespan is un-affected
- All Sandybridge CPU's worldwide should be run at the above or lower voltages, no higher!

which is better/safer:

multiplier at 46
turbo power limits 200, 200
additional turbo voltage +0.055
CPU PLL Voltage 1.750v
vcore mode to auto
LLC level to 4.

which gives me 1.31v in IBT

or

multiplier at 46
turbo power limits 200, 200
CPU PLL Voltage 1.750v
vcore mode to auto
LLC level to 3.

which gives me 1.31v in IBT and better idling voltage of 0.094v
