Morning Mr 8 Pack, i am hoping that you could give me some advice please, i have posted this predicament in a few areas, but i am trying to obtain as much varied feedback as possible so i can make an average/general consensus decision from it all. Please see the following.

I have been tweaking and playing around with my OC for last few days, ive managed to get a setup as follows.

I5 2500k
4.8ghz
MB Gigabyte Z68AP-D3

M/B intelligent tweaker
Advanced Frequency Settings – Press Enter
CPU Clock Ratio – 48
Advanced CPU Core Features – Press Enter – Ensure that CPU Overvoltage is enabled
Advanced Memory Settings – Press Enter
System Memory Multiplier – 16.0
Performance Enhance – Standard
DRAM Timing Selectable – Quick
DRAM Timings - 11-11-11-28-2
Advanced Voltage Settings – Press Enter
Loadline Calibration – Level 7
CPU Vcore – 1.300v
DRAM Voltage – 1.58v (team group elite- recommended not above 1.6)


I ran prime for 6 hours, no errors, no BSOD, thought it was all gravy, temps acceptable at about 72-73c.

Closed prime, went to watch a film, loaded page buffered a bit, got 2 min in and pc hung its self, no BSOD, just locked up, i incresed core v by +0.015 and rebooted, buffered film, got 40 min in and same again but with BSOD ( message said something about cpu not responding quick enough) i also lowered clock speed to 4.7 before second hang to see if it would help rather than increasing core V.

My only thought with this oc is that due to me using onboard graphics, could this be choking the cpu?, can anyone recommend any thing i can try changing in the bios to try and stabilize it.

Im new to this so any advice would be great, thanks in advance

And this will be why you advised me to =), i think

"Your DRAM voltage should never be more than 0.5 V above VTT, or it could cause system stability problems. Since the default VTT is 1.1 V, this means that your DRAM voltage shouldn’t be higher than 1.1 + 0.5 = 1.6 V–unless you also increase VTT. So if you’re using memory that has a default voltage of 1.65 V or you’ve overclocked to that amount, you should increase your VTT voltage to at least 1.65 – 0.5 = 1.15 V."

If my VTT is only 1.1 and my ram is oc at 1.58 it may be causing stability problems
 
Sorry, the above was a cut and paste whilst on my travels, i was thinking that the reason you said about the vtt was due to the V gap being too great from the cpu to ram.

I have ram that only runs 1.60 so 1.65 is out of it i think.
TeamGroup Elite 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel, this is my ram.

When you say tune for stability its just trial and error to see if it hangs right? i did notice there are some auto tunes on the bios settings for these setting areas
