Smart OC

trubster · 21 Apr 2015 at 01:54

I have a Asrock P55 board which has "Smart OC" built into the bios, I set it to overclock on the "50% Performance increase" preset and it failed to boot to POST

I reset the CMOS Settings and its all back up and running, I am guessing the bios presets are no good, so I need to set it all manually.

What would you guys recommend for starters? Cooling isn't an issue any more, its running at 26 degrees idle and I haven't been able to get it above 35c!

Thanks in advance

Thanks for that PastyMucher

Will give ti a go and come back to you.

Its handling 4GHz Very well.

It was running at 27c idle without overclocking - now 32c

100% CPU went up to 35c and now its 50c

It would appear that the problem last time with the boot fail could be related to the memory... Me thinks I have fried a stick?

Try running memtest on it.

I ran memtest+86 on it and it passed

It shows all 4 sticks @ 4gb each but in the top left it shows memory as just under 8000MB

I had it before and it turned out to be a faulty stick, hopefully its a corsair one as they have a lifetime warranty. Already had 1 replaced with no questions asked.

On a lighter note, I have selected 4.2GHz in the OC Tweak screen on the bios and its running ok. Took 3 tries to boot to post, but it worked.

OC tweak, is that a auto overclock thing? What voltage is it using for 4.2Ghz because auto overclock tends to overvolt?

OC Tweaker is the BIOS OC Settings Menu

It is running at 4.2GHz (2.8 GHz Chip)

Turbo 50: Increase 50%

EZ OC Setting: 4.20GHz

Overclock Mode: Manual
BCLK Frequency: 200
PCIE Frequency: 100
Boot Failure Guard: Enabled (3)

CPU Ratio Setting: 21
QPI Freqquency: 6.400GT
DRAM Frequency DDR3_1200 (The ram is DDR3 1333?)

Voltages:

Asrock VDroop Control : Without VDroop
CPU Voltage: Manual
1.47500V - RED
DRAM Voltage: Auto (1.559V)
VTT Voltage 1.309V
PCH Voltage: 1.120V
CPU PLL Voltage (1.903V) - RED

I am quite new to this, I have turned the voltage down expecting it to slow the CPU down, it didn't.

There was an option to select "Turbo" which I guess maxes out the CPU

It is running at the voltage I set below 1.4v and running at 4.4GHz. What an awesome chip!

If it goes pop, never mind, I will be buying a new board and CPU when the wife gives me my bank card back

I would be happy with that. 4.4Ghz is excellent. What are the temps like now?

The temps are the same as when it was running at 3999MHz

Idle 35c

Full load (10 mins) 52c

BUT the fan's are not controlled, they are on 100% all the time as the pump is in the CPU1 fan socket, and I only have 1 of these 4 pin plugs on the board, so no control over the fan speed and its LOUD

Mahoosive difference in speed. So I should be safe running it at 4.4 with the voltages specified in the last screenshot?

Yes, that's all good. With regards to the fans, is there no fan control in the bios? My board has a couple of 4 pin headers but I can also control the 3 pin headers from the bios if I wanted to. You could buy a cheap fan controller or invest in a pwm splitter cable such as this, this or this. There's a posh version with braided cables here for 5 fans too. You don't have to worry about them overloading the motherboard header as they get their power from the molex or sata connector.

I have got the one that splits the 4 pin connection (I only have 1 on my board). I set the bios to Level 5/9 with a 50 degree target.

It is running ok but what was putting me off the splitter idea is the fact that reducing the speed (power) will in turn slow down the water pump won't it?

The case I got has fan cables that come off a SATA cable, but I put them all on the board and tied the case cables out of the way. If the mobo controls the fans then it is a lot quieter.

Would you recommend leaving it as it is or should I plug the pump into the SATA/Fan connectors (they have a 4 pin socket with only 3 pins in)

BTW: What a lovely place Aberlour is

I need to go and do the whisky trail when I am next that far up.
