Overclocking i7 930 and Kingston HyperX with X58A-UD7
  

Hi,
I had added a Core i7-930 processor to my Gigabyte X58A-UD7 motherboard. Other than this I had added a 4GB Kingston HyperX RAM for further support. I want to play some high end games for which I want to overclock this processor. But as the entire configuration is upgraded except the motherboard I feel that while overclocking this might not create issue. Has anyone overclocked the same on similar system.

The QPI is closely linked to the base clock and is set for 133 MHz to 2.40 GHz latter for i7 920 and 940 or 4.8 GT / s. This coefficient (QPI data rate) is set to X36. Here we do not need to seek its maximum, we know that almost all i7 support at around the 8 GT / s and as in our case we will not exceed 200 MHz we bclk 7.2 GT / s to this frequency. To the max CPU, we know that all i7 take at least 3.8 GHz. All you can do is perform some free test of the processor to checkout the stability.

Whether you chose a motherboard that we recommend you to visit the intel site for some motherboard recommendation. In theoretical maximum of 222Mhz bclk is supported. . This would give 20 times 222 MHz = 4.44 GHz for your i7 920 is too air cooling. I had done the same for the choice of memory is at least as the PC12800 OCZ DDR3 PC12800 2GB x 3 Gold Edition that gives you 1600 MHz (800 MHz actual) with 8-8-8-24 timings 1.65 volts (in fact it will take more to stabilize high frequency). The predicted maximal heart rate of the ram to be 4 times lower than the uclk.

The clock is uncore a new frequency introduced by the integration of memory controller in the I7 (or new I5 and I7 8). This frequency corresponds to the frequency of the controller. It must be at least 4 times greater than the frequency of the RAM. For example, a RAM clocked at 800 MHz, the clock will be uncore 4 X 800 or 3200 MHz. The frequency of uncore conditions that of the RAM out of sync and it will take to achieve the desired value depending on the frequency of the RAM using the ratios suggested in the bios.

Re: Overclocking i7 930 and Kingston HyperX with X58A-UD7

One could equate the basic clock of the FSB Core 2 Duo. This is the bus frequency processor, originally set to 133 MHz. It is this frequency multiplied by the multiplier of the CPU that will give its frequency. For example, an i7 920 is clocked to 2.66 GHz corresponding to 133 X 20. Not everything is so simple because the Core i7 platform organize their operating frequencies (core, uncor, QPI and memory) around this frequency, the base clock which is internal to the CPU.

Intel recommends not to exceed 1.65 volts for the voltage of the RAM (VDIM) failing to grill its core i7. In fact this is not the voltage that is dangerous but the delta (difference) between the too high voltage and ram voltage controller. Must avoid exceeding a delta of 0.3, max 0.35 volts to avoid damaging the processor. So with a voltage controller, for example 1.4 we arrive at 1.4 + 0.35 = 1.75 Volts RAM safe.

Yes you might as well assume that Core i7 - 930 heats more than the Core i7 - 920, so be careful to overclock. I read that the 920 Intel processors overclock is well. Have you heard something like what the 930 overclocking less than its big brother? It's weird but I think I read it somewhere for marketing issues (why take a 950 in double the price a 920 is easy when the boost).
