Unstable 3770k 4.5 Ghz - Page 2

post #11 of 13
Thread Starter 
So... I followed the guide you sent me and noticed that my chip needed way more voltage then the graph he proposed. I started at 4.2 GHZ and went up until 4.4 GHz. I putted my LLC and Phase Control to turbo. Prime95 runned for 5 hours until my PC crash at 1.310 V (CPU-Z was showing 1.308V).

Prime95 has now been running for the last 8 hours with no error at 1.315V (CPU-Z still showing 1.308V). I'll let this run for another 4 hours to make sure, but if I'm stable under those conditions, it just means I have a bad chip comparing to others cause the highest voltage needed according to the spreadsheet you show me was 1.280V.

Frequency : 4404.3 Mhz
Max Temp : 72 - 78 - 76 -74
vCore : Bios - 1.315V CPU-Z - 1.308V
Vid : 1.3561 V

Is it worth it to run my CPU at this voltage in the long run or is my chip just a bad overclocker and I should stick with default frequency?

Thanks!

Usually people with bad overclockers would not post in that stability thread, so those numbers would be skewed to the low side with voltage needed. My first chip, that ended up being returned, needed 1.27v for 4.4, and I have seen others here who needed higher. So it is possible that you got a really bad ocer.

Just because it is not a good ocer does not mean you can’t run it at 4.4. If you could do 4.6 at that voltage then you would have a decent chip, but it is not like in real life someone can always tell a difference between 4.4 and 4.6. But 4.4 vs stock is still a nice oc.

That said, I don’t have a Gigabyte mobo, so I can’t tell you specifics but I would suggest double checking that you have all the settings correct – it is very easy to make a mistake when first overclocking. Also have you made sure there is nothing wrong with the ram? Have you run memtest86+ overnight?

No I did not test the memory. I will tonight to make sure it's fine. Thanks!
