Core 2 E6700 overclocking with MSI P7N 780i / some advices

idata · ‎10-07-2010

Hello,

I have a Core 2 E6700, 266X4 = 1066 Mhz FSB with 2X2 GB PC8500 1066 Mhz RAM on a motherboard MSI P7N 780i chipset nvida. I also have two graphics cards in SLI GTX260.

I already have my CPU overclocked to 2.66 GHz (266 X 10) to 3.00 GHz (300 X 10) by increasing my FSB from 266 to 300 and this poses no problem. I just grew a bit my "voltage" of 0.0125 for my bios to 1.33 or 1.35 in CPUZ. I also manually set my memory for it to pass a frequency of 800 MHz to 1066 MHz (533 X 2) 5-5-5-15 and putting in the "DRAM Voltage" to 2.10.

Of course, I think I can go to 3.33 GHz, 333 X 10 but trying, it does not work.

Can I get advice on values to indicate in my bios:

1) CPU Voltage?

2) DRAM Clock (MHz): indicate what value to reach 1066 Mhz? Is this a good ratio?

3) The values of Northbridge (1.30) and Southbridge (1.575) should be changed?

Thank you in advance for all your good advice, below the screens of my bios:

FYI, I chose not to link the increase in memory the FSB (unlinked mode).

I actually have a choice in the menu "system clock mode between" Auto "," Linked "and" Manual "and this last one I chose. Is this correct?

In fact, I did a test by increasing the FSB to 333 with a value of 1082 MHz RAM to arrive at an adjusted frequency of 1066 (see diagram), without changing the Vcore and it crashes ...

Bios currently works ....

Hello;

Overclocked processors can produce unpredictable results or system instabilities, which might not be readily apparent. The life of the processor may also be shortened. This operation will also void the warranty, for more information check the following URL:
