Natural Sub-Zero Overclocking
Not long ago we reviewed a few Intel 915 motherboards here on PC Perspective. In response to one of those articles, Robert (a reader who linked in from [H]ardOCP) wrote me giving me input on the overclocking tests featured in the articles — specifically addressing the importance of synchronous CPU-Memory overclocking at the default multiplier.
While I agree that doing this kind of synchronous with default multiplier overclocking is important, I prefer to use a 14x multiplier (vs. the 18x default) and asynchronous settings because it gives us a better idea of how the motherboard itself functions at high frequencies without the RAM or CPU being bottlenecks.
But Robert's comments got me thinking, what if I got these LGA775 motherboards cool enough so I can test using the default multiplier with synchronous RAMâ€¦ ? So using Robert's email as inspiration, I've taken the Chaintech V915P, the Asus P5GDC-V Deluxe, and the ABIT AG8 and put them in sub-zero temperatures for some serious overclocking!
Since we are only testing 3 motherboards, it's hardly enough data to make grand conclusions like 'the best 915P' overclocker. This is just an interesting experiment whether the results are useful or not.
For this experiment, I am using the following setup for all three motherboards:
|CPU||Intel Pentium 560E (3.6GHz)|
|RAM||2x 512 Corsair CMX PC3500|
|Video||ABIT Radeon X700 Pro 128MB|
|HDD||Western Digital 120GB SATA150|
|Power Supply||Antec TruePower 430W|
|CPU cooler||Stock Intel LGA775 cooler|
I live in Northern Ontario where it gets pretty cold overnight. Temperatures drop to -19C fairly regularly which makes great weather for overclocking! Just have to make sure to avoid condensation. O_o
This is a 6-day forecast for my area. -21C on Monday?!
Awww man! :(
