Overclocking Question

Over Christmas I completed my first PC build (link in sig) Basically an AS Rock z68 Extreme4 Gen3 with an i5-2500k

I am not interested in extreme overclocking but a basic increase would be nice. I have been into the bios and changed the turbo boost to 4400 and saved.

Is this really all there is to it? Looking at the tuning utility the CPU speed says 4400mhz CPU temp 46C (nothing running) and I see my voltages with a DRAM voltage of 1.605v I thought I had read somewhere that this needs to be 1.5v but that might have been in relation to something else.

Any advice appreciated
 
Sorry I think an update was running in the background, a Gellid Tranquillo cooler and idle speeds are 32C jumping to 36C and back down again every 10-15 seconds
 
CPU-Z reads 1.336 core voltage

I used the Turbo Boost function that comes with the mobo, you select one of the speeds from a drop down and it says it will auto configure best options.

Using the ASRock extreme tuning utility interface here is what I see:
BCLK/PCIE Frequency 100.00MHz
CPU Ratio x 44.0
GT Frequency 1100MHz

VOLTAGE
CPU Voltage Offset +0.055 V
DRAM Voltage 1.605 V
PCH Voltage 1.059 V
CPU PLL Voltage 1.051 V
VCCSA Voltage 0.925 V
IGPU Voltage Offset 0 mV

Each of those readings has a slider next to them so that they can be changed.

Prime95 is now running test 16 and Min Temp is 56 (was 53 at start of test) and Max 63 (was 62 not been above 65 yet)

Replying here on a different machine..

EDIT - As the tests continue into 800000 Lucas........ temps increased to a maximum of 71 but dropped back to 68

Okay I am watching my core voltage fluctuate around 1.272 and 1.334 I guess the system is making the changess as they are called for?

Are you still being overclocked automatically?

Yes I wanted to leave the test running or a full one hour, it has finished now and will go through your suggestions trying 10 minute runs.

First thing is what memory are you using ?
Your MY First Build link says Corsair 8GB (2x4GB) DDR3 1333MHz XMS3, but I can't find details for this on the overclockers site. Did you get it elsewhere or is it supposed to be Corsair 8GB (2x4GB) DDR3 1600MHz XMS3.
In which case go into the bios and set the XMP profile which should set the timmings to 9-9-9-24 then check the DRAM voltage, you can set this manually to 1.55v.

Capacity 8GB(4GB x 2)
Cas latency 9-9-9-24
Memory speed DDR3-1333Mhz
Test voltage 1.5v
Warranty Limited Lifetime Warranty

Ok have you set the XMP profile or set them manually,so it gives those timmings 9-9-9-24.
And set the DRAM voltage manually to 1.5v then.

I haven't set any profiles, that is what they are advertised as. When I check using CPU-Z it confirms 9-9-9-24

I have set the DRAM voltage to 1.5v and running another Prime95 test, cores are running at 54C 53C 58C 57C fluctuating by 1-2 degrees maximum

No probs, once you've got a nice stable setting at 4.4GHz you can save it in the profiles at the bottom.
Then either try 4.5GHz manually or even try the auto 4.6GHz auto OC.
When you run IBT set it to Maximum Stress Level for 10 runs, and have CPU-z and Core Temp (or Real Temp) open on the desktop. Then take a screenshot when IBT is halfway through the last run, this will show the max temps(try to stay under 75c) and the vcore.

On the 4.4 setting I was hitting around 71C max (on your suggested initial settings so I haven't lowered the offset yet) I am happy with that for now and I will try with a lower offset shortly. I wasn't going to OC (hence my choice of cooler) but as this was my first build it seemed a shame not to at least push it a little.

I think before I try and extend on 4.4GHz I shall buy a better cooler but all the advice has been invaluable from all thanks :)
