Z68 Extreme4 Gen3

Always check the memory. That's usually a show stopper if it's not configured right, or doesn't have enough juice. Look up the motherboard debug digits, that should tell you where it's gone wrong. If it's the memory and you cant get to the bios, clear the cmos.

Thanks what's the diff between 1/2N and also what does having the voltage set to 1.65 over 1.50? Thanks

They are settings that usually depends on memory quality. The more stable settings are higher voltage, and 2T (memory command rate). The XMP profile basically tells you what the manufacturer recommends for safe and stable operating values for particular memory sticks, and you should stick to those. If you still have problems, increase the command rate (2T), and increase the voltage a bit.

Higher volts means more stress on the component, but increase in stability (more signal to noise ratio, if you will).

Sandybridge memory controller prefers lower volts, so it's always good to push the volts down, ideally 1.55V, 1.5V.

All in all, it is best to stick to the recommended values, and then tweak them although the performance gains will be marginal. If you are having stability issues with XMP values, you can increase the vram voltage little by little (0.01V to 0.05V increments), and set the command rate to 2T if 1T is recommended. Do not exceed 1.65V.

ok got my memory profile setup and not ready after stressing the default cpu with prime to try my first overclock, any tips?

Leave the memory settings alone (although if you are pushing 1.65V, try lowering it), use the asrock overclocking profiles (can't remember what they are called, but you should have profiles for 4.2->4.8GHz), run some stress tests, and if stable, decrease the Vcore manually little by little. There are other tweaks to increase stability, but the profiles are a good starting point (except the vcore settings they use, which are usually conservative and can be lowered).

Ideally, Vcore around 1.3, 1.35V max, keep it under 1.4V.

Thanks mate
 
getting this thing where i can't boot sometimes, happens once a week, and you're stuck in a loop, error code 60 or 70 on the red clock. H/W monitor saying cpu is 92degs but when i do get into windows that states its only 23degs?
 
Error 60 and 70 are related to the UEFI BIOS (DXE module).

try a bios reset. Run at stock for a while.



Don't forget the AHCI SATA mode, boot order, and checking if your drives are seen properly by the BIOS, and also checking the health status (fan speed, temps).

Can also run a BIOS flash.
 
i restored the bios defaults, and may have been cos i played around to much, just using a simple overclock @4.4 and running fine under prime for the last 2 hours max cpu @ 52degs.
 
i think so, so i reset the bios and then just used the stock overclock to 4.4, during prime stress test the cores hit 50degs? is that ok.

also can i ask any other bios tips, tweaks or advise, so much of it looks alien to me
 
50C looks good, really. Note that the limit is 75-80C, but 65-70C is a good ceiling value.

Try lower the voltage of the CPU in the bios. What is it set at? I would expect over 1.3V, but you may be able to lower it.
 
I just want to big this board up. It is great for 1 click overclocking and also more enthusiast overclocking with so many options.

I had 1 problem where it wouldn't regognise my G510 KB at the bios page but soon as I used another KB to flash the bios no probs at all.

Asrock did done good :)
 
thought i would rather ask in here than start a new thread, so im happy with my bootup times, windows and 90% of my bios settings, got a stock overclock at 4.4 which im happy with, 4.6 worked most of the time but i got the odd crash so will just leave @ 4.4.

Anyway just wanted to ask about the cpu setting, mine drops down to 1.6 when not doing much, i guess its the speedstep thing ? powersaving? - what do you guys do with that just leave it or turn it off?
