Gigabyte TweaKING OC Event

European Final

Manufacturer: Gigabyte

Gigabyte are well known for its overclocking events: the Gigabyte Open Overclocking Championship (GO OC) ran earlier this year and encouraged competitors to overclock their Core i7 CPUs using any means possible, and ran Super Pi 8M and 3DMark 06 for the best scores.

The TweaKING event in Paris is the European leg of this new style of OC tournament. Less emphasis is placed on the quality of CPU and more is placed on the ability of the teams to tweak the memory and motherboard. How? The CPU frequency is capped at 4GHz, meaning the teams had to crank the memory and baseclock on their Lynnfield i5-750 CPUs up as high as possible to achieve the best result.

This still puts an emphasis on CPU quality to some degree, but its also brings the motherboard back into play more, which is an angle Gigabyte obviously wants to push. There was no limitation on the OS tweaks allowed too; so WinXP hacks a plenty were rolled out: services were neutered, registry was copiously tweaked and anything deemed excess was cut off.

However, every team had a standard set of hardware to use: nothing extra was allowed, not even an additional fan. Even screwdrivers were provided!

Overclocking the ATI Radeon HD 4770

One thing we unfortunately had to cut out of our AMD ATI Radeon HD 4770 review yesterday was overclocking. Understandably, a number of our readers asked why we'd not bothered to overclock the card.

The answer is that we simply ran out of time when we made the decision to double (and triple) check all of our Far Cry 2 performance numbers when the new Radeon came out on top against the cards we'd compared it to. Although the results were theoretically possible - compared to the much-loved Radeon HD 4850, it has a higher pixel fillrate and very similar theoretical shader throughput (it's just four percent lower), we wanted to be not just doubly sure, but triply sure before publishing our conclusions.

Yesterday afternoon, I dragged myself back down into the benchmarking sweatshop that is the bit-tech and Custom PC labs to find out how well our reference card overclocked. It's worth noting that it's not the only Radeon HD 4770 we've got in house - there are a couple of partner cards already and we'll be looking at them in due course - but we've only focused on overclocking the reference card for now.
