The Core i5 750 is a great processor in the sense that it is cheap and a magnificent overclocker. However it has been the combination of the Core i5 750 and the ASUS P7P55D motherboard series that has impressed us the most, at least when it comes to overclocking. Already we have spent quite a bit of time playing with P55 motherboards from makers such as Asrock, DFI, ECS, EVGA, Gigabyte and MSI and while some have been able to reproduce this impressive 4.20GHz overclock none did it as easily.

I use CPUZ, HWMonitor, TMonitor and Prime 95 for testing. |

I'm using P7P55 LX MB and set shown settings in my BIOS, but a friend of mine told me to leave SpeedStep disabled. I noticed 45 C on my CPU, so I enabled SpeedStep to reduce cpu temp and just after loging in Win7 I had a BSOD. Everything runs smooth with SpeedStep DISABLED, why? I found out that C1E Support is disabled as well. What can I do to have SpeedStep working properly? |

Hi all  I have also got i5 750 with an Asus p7p55d deluxe board and i have followed this guide(btw is great and easy for a oc noob like me) i then run the prime95 torture test and this results in "FATAL ERROR: rounding was 0.5,expected less then 0.4" Does this mean the OC is not stable and please anyone who could help me out it would be much apreciated! Thanks |

If P95 is reporting rounding errors your OC is not stable. Try running OCCT - it's great for quick tests (takes an hour to complete). Will help you find your lowest vcore. On that note what is your vcore- from what I've seen around 1.4v should be enough for the 4ghz range on 750s. I can't agree with leaving vcore on auto. 1.514v is crazy high. I may just have a cherry chip but mine has run stable 3.6ghz @1.24v for more than a year. Turn off all the power saving features and turbo as well as they will make it harder to get a 100% stable OC. I happened to stumble on this when trying to find the max speed people are getting on these guys since my upgrade path was decided with the lackluster performance of BD and I'm less concerned about longevity. Wasted 169.99 on a 990FX board last month. Should have stayed faithful. IB seems to be where I will head to. |
