GA-Z68X-UD3P-B3 + 2500k = 5.0 GHz so far

[absic]

Just thought I would post a little image for your perusal of my current set-up with the Intel i5 2500k running at 4.8GHz.



I'm sure I can clock this little baby a bit higher than this but I am going to have to leave it for a little while before doing so.

For those who are interested, my current settings are:
CPU Vcore  = 1.375V
Multi-Steps LLC = Level 6
BIOS Version = F8d
CPU Enhanced Halt (C1E) = Disabled
C3/C6 State Support = Disabled
CPU Thermal Monitor = Disabled
CPU EIST Function = Disabled
All other BIOS settings under the MIT Section are set to AUTO or Default except for the RAM which I have set to 1600MHz

Max Temp with my Noctua NH-D14 is 64C

   Cooking with Intel gas now matie ..... and you've got the clocking trick down pat ...... turn off everything except the power

       I'm sure I can clock this little baby a bit higher than this but I am going to have to leave it for a little while before doing so.                    

  So when does the policy start ? .... I'm going to be watching this space for when it does ..... you can also use the egg trick.....crack one over the CPU cooler ...... if it starts turning white...... back it off 10 Mhz....

  Seriously Absic....great result mate for someone so new to Intel

29 days before the insurance kicks in. 

I have been playing around with O/C'ing for a little while now but have struggled to get past 4.5GHz until today probably the latest BIOS has helped.

In my earlier attempts I did get to 5.0GHz but, for some reason, after running a stability test for over an hour without issue the PC on next BOOT decided it didn't like my settings and after resetting itself to defaults it wouldn't let me run above the 4.5GHz mark.

There is still some more headroom with the set-up and I would like to see if I can get a 2.0GHz (or higher) O/C from the system without resorting to water cooling everything.

  What was the temp and Vcore at 5 Ghz ?......AA

[absic]

That depends on which software you take as being accurate.

HW Monitor showed it as 72-75C
TouchBIOS showed it as being 10C lower

[Aussie Allan]

  and the Volts AA

[absic]

1.4V LLC set at 6

[Aussie Allan]

   So you DO have a big set to go with your Hero Member ...... can't wait to see where you go with a policy over your head....

  AA

Although the Noctua is a very impressive cooler it is beginning to be pushed to its limits. I may be able to improve things temperature wise once I do some fine tuning with the Voltage and other settings but I'm really not sure how much higher I will be able to go with my current set-up.

Oh well, I've switched to Intel, so now, I may have to also switch to Water Cooling! 

[Aussie Allan]

   Yup! ..... Once we have the right equipment ..... first we walk ..... then we fly .... who wants to run anyway

  Thermal goop can help .... but not as much as water!...... now goop and water

I haven't applied for one of these policies yet but the do seem to be a brilliant idea if you plan to hit the OC hard. Did you have to fill in a form with all the CPUs details on it when you purchased it ?

Your overclock seems to be going very well absic. Shame about the 5Ghz fail on the next boot wasn't it. I reckon that was just down to a poorly written BIOS.

[absic]

The 5.0GHz issue was with an earlier BIOS (F8c) but now running latest (F8d) and that seems better. I did have a couple of minor issues with teh system going through the reboot cycle mentioned in other posts but that only happened a couple of time and since getting to 4.8GHz it hasn't happened again.

When you take out the Intel Protection Plan you do not need any specific details about the processor apart from the model type. It has to be a retail version but they do not ask for serial numbers or anything like that. You need to register your details prior to taking the Protection Plan out and you have to pay for it using PayPal but, apart from that, it is really easy to do. If you are not from the UK or USA remember to double check that your country is covered by Intel as it seems as if, not all are yet.

Hi absic,

Likewise I have just enrolled on the plan. It is brilliant for the price.

[absic]

Well, it definitely give a little more confidence when it comes to pushing the CPU and, if the worst does happen, at least you know it isn't going to cause a hole in your pocket to replace it.

CPU Enhanced Halt (C1E) = Disabled
C3/C6 State Support = Disabled
CPU Thermal Monitor = Disabled
CPU EIST Function = Disabled

Did you have to disable these to get to 4.8?
