BIOSTAR TP67XE Intel LGA 1155 Sandy Bridge Motherboard ReviewMon, Mar 14, 2011 - 12:00 AM
Overclocking the BIOSTAR TP67XE Motherboard
Overclocking greatly varies due to what hardware is being used and who is doing the overclocking. Always remember that no two pieces of hardware will perform the same, so our results will differ from what you might be able to get.
Overclocking with the new Sandy Bridge processors has been simplified, at least in part. Adjustments to the Bclck have been all but done away with and overclocking is almost completely done through increasing the multiplier. When overclocking we used to run out of room on the Bclck or cooling. Now we are going to be limited by the Multi-wall. The Sandy Bridge processor just isn’t capable of going any faster; it’s all dependent on the piece of silicone that you get when you purchase your processor.
The Intel Core i5 2500K utilizes a bus speed of 100MHz, though the BIOSTAR TP67XE is picking it up at 100.1MHz. Under full load the Intel Core i5 2500K uses a multiplier of x33 to achieve the final clock speed of 3.3GHz. Since we are using a K series processor which has an unlocked multiplier we will be able to increase the default x33 multiplier to achieve our overclock today.
With a little bit of work I was able to bring our Intel Core i5 to a solid 5GHz by increasing the multiplier to x50 with a voltage of 1.5. With a lower multiplier I was able to increase the Bclk to 101.6MHz. Once I was pushing the multiplier up to x50 I wasn’t able to increase the Bclk on the BIOSTAR TP67XE and achieve any stability.
Firing up wPrime is a great way to see how much faster your system will be once you complete your overclocking. Running the 1024 Million benchmark we were able to knock off 110.664 seconds off of the total time. This is an improvement of 31.8%. If you happen to have the Intel Core i5 2500k and the BIOSTAR TP67XE motherboard or are simply curious about the settings I used you can find them here and here.
