2. Re-run MemTest 86 just in case. Have not used Kingston ram before.
Test completed after 42 minutes. No errors and test completed ok.

Small problem, memtest86+ doesn't 'Complete', the program will run continuously until the user reboots.

If it stopped it is because it had a major failure/error.

With 8GB RAM it will take 8-12 hours to complete the minimum 7 passes.


Can you download CPUZ and post a snip of the CPU, Mainboard, Memory, and SPD tabs.

Go to your BIOS and tell us what the CPU, RAM and the CPU integrated memory controller voltages are.

What were the CPU core temps when running Prime95?
If you didn't check it, then run Prime95 again until the CPU core temps stabilize, don't go over 77.6°C.
Intel® Core™ i7-2600K Processor

Hi Dave76

Thanks for your response.
1. I stopped memtest86 after 42 minutes. Thought it was on pass 8 when I
stopped it as to that time no errors had been found.
2. After 2 + hours of running Prime95 temperatures were 63-67 degrees Celsius
and 67 degrees was on Core 3 and those temps had been constant for over 1
hour.
3. I have attached CPU-Z rar file as requested.
4. O/C this machine was my 1st attempt and I used this guide: http://www.clunk.org.uk/forums/overclocking/39184-p67-sandy-bridge- overclocking-guide-beginners.html
(refer#2 4ghz section). I believe I followed instructions to the letter.
5. As a novice your paragraph 5 your requests re CPU,RAM and CPU integrated
memory controller voltages leaves me perplexed. Only voltage I can find in the
bios is CPU voltage (+1.12volts). could you point me to where in the bios
to where I might find those entries (Asus P8P67 PRO m/b).

Your assistance is appreciated. The computer is on 18 hours/day and basically after 2.5 days no blue screens of death.

Regards

Please post CPUZ snips.

Run memtest86+ for a full 7 passes, when pass 8 starts you can stop it, this will take up to 8 hours or more.

For the integrated memory controller: VCCIO is the I/O voltage for the memory controller.
The RAM voltage is DRAM Voltage.

Hi Dave76
I had uploaded CPUz rar file containing CPU, Mainboard, Memory, and SPD tabs.
Will try posting screenshots as requested.
Attachment 169188Attachment 169189
Attachment 169190Attachment 169191


Dram Voltage 1.653 volts
VCCIO 1.037-1.056 volts (varies between those values).

Will rerun Memtest86 overnight and will advise results.

First as in the link you posted, I recommend to set your RAM to 1333MHz (666.7MHz) and lower the DRAM voltage to 1.500v.
This will put less stress on your CPU.

If you've caught the OC bug, then start lowering your DRAM voltage, say 0.05v for a start, if you get to 1.50v - stable- then leave it there.
If you get a crash, then start raising it 0.02v until stable (memtest86+).

Change the VCCIO to 1.100v and check for stability (memtest86+), do this only if you get another crash.
Raising this voltage too much will cause problems for your CPU.

To be honest, running your system at 1600MHz or 1333MHz will not change the performance, I would run the RAM at 1.50v and set the frequency at the necessary MHz.

Let us know how the memtest86+ test went.

Hi Dave76

I ran the memtest overnight and have just stopped it at 12hrs 08mins.
No errors found so I assume I can discount the RAM as the cause.
I note your suggestions. Will change to 1333MHz and lower the voltage to 1.5.

I will leave the O/C at that and see if that fixes the issue.

Many thanks for your assistance. I will get back to you if problem occurs again.
