i5-760 overclocking

post #1 of 26
Thread Starter 
Need a bit of advice regarding an i5 760.

I have oc'd to 4GHz and thought all was well.

I used either 210 * 19 or 200 * 20 (sorry, bad memory :\\ ) and 1.264 V

I ran Intel Burn test and it was fine, then ran intel burntest on the Highest setting and I blue screen every time.

Now I personally thing its my RAM because I have never owned DDR3 so im not sure what timings and V should be.

could anyone enlighten me what I should be doing with my Ram? theres like 20 odd timings now. Im used to 5 or 6! :|

Ram voltage is another thing im not too sure on anymore.

I own a P7P55D - PRO motherboard.

Thanks,

- Kieron

Edit: Here is a CPU-Z validation for you guys to see all my settings
The only change is the Multiplyer is now 21 and the bus is 195

Edit Edit: My temps are also fine. 70c is the highest I have seen

Kingston makes a few different models.

What is your ram rated at? It looks like it could be 8-8-8-24 @ 1.65v or 7-8-7-21 @ 1.65v

If you open the SPD tab on cpu-z it will show you.. But if you have the actual model number its better...

Saw your edit.... Your ram is ddr3 1600 and its running at 1066... I doubt its the problem..

Make sure voltage is set to 1.65v and set a 2:8 divider...

What is your QPI/VTT voltage at?

According to this you should set your memory voltage to 1.65v. Do that. Then set your timings to 9-9-9-24. That is loose enough that if you BSOD on those volts and timings it's most likely a cpu overclock failure, not a memory issue.

Make sure that as you over clock your cpu that the memory does not exceed 1600. After you have a stable cpu overclock, you can start overclocking the memory.

According to that your ram voltages are at 1.5v. Up that to 1.65v and your BSODs will most likely stop.

silly question. How? what would it be called?

I just changed the DRAM to 1.65 (thinking that was the ram voltage) but it hasen't changed. :S

Found this. It seems there is a bug with CPU-Z and memory voltages. What was the voltage at before you changed it? If auto, try running intelburn now with it a 1.65 and let us know what happens.

... I think this may be unrelated to my overclock.

I managed to get a picture of the BSOD before it dissipated. I think its HDD related.

hey, I've got the same problems but at higher clocks. U can look here, maybe you can find some answers http://www.overclock.net/intel-cpus/...6ghz-help.html

Maybe bump up a little the Vcore?

124 is uncore. What is the VTT or IMC , QPI voltage at. (uncore voltage) Not sure which your bios will call it. Stock is around 1.1v and you need to keep it within .5v of the Dram Voltage at min. For 200-210 baseclock you'll probably have to bump it up quite aways. 1.25v is probably a good place to start. 1.4v would be the recomended ceiling.
