Overclocking with Gigabyte P35C-DS3R and Intel Q6600

Overclocking/Overclocking Tests by KeithSuppe @ 2008-03-27

Overclocking successfully requires a mix of the right components, we take a closer look at the pinnacle of affordability and performance product from Gigabyte, the P35C-DS3R, testing with a Quad Core Q6600 we see how we can fly with a water cooled CPU and some spicy DDR2 memory modules.

Gratis Introduction

Gigabyte P35C-DS3R:

Over the past years an ever increasing number of articles featuring products by Gigabyte begin with the obligatory statement: "Gigabyte needs no introduction.." Ironic how saying nothing about a company can say so much. Gigabyte is a mainstay with 22-years in this industry converting like dog years compared to any other. I purchased my first GA-7VRX KT333 board over eight years ago. That was when $125 would buy the best board on the market. Times have changed but some things haven't. Gigabyte's Dual BIOS still remains a mystery to me and fortunately for the consumer Gigabyte is still building feature rich, performance oriented motherboards for an affordable price. The P35C-DS3R (Rev. 1.1) is no exception. Removing everything from the box reveals a spread of ancillaries including SATA-II cables with locking mechanisms. A nice detail.

Essentially Gigabyte's P35C-DS3R is a hybrid DDR2/DDR3 version of their P35-DS3R with the following DDR2/DDR3 memory supported. Insofar as processors the board supports most Socket-T processors including current Wolfdale and Yorkfield cores for those in a 45nm frame of mind. Gigabyte also provides a current list of supported processors and BIOS revisions required to run them. Another nice detail.

    Nicely written Keith ! Good thing you linked to Anand : the vdroop article by Kris is one of the best OC articles I've ever come across!

    Did you play around with the tRD (static tRead value) setting to try and increase FSB above 445 ? You should also have a look at Kris' follow up article to the vdroop article, and see what's the impact of tRD.

    Only pity in the review imho is the fact that DDR3 was not tested at 400x8 as well, then we could have comparable results to DDR2. At 266FSB DDR3 on this board seems slightly faster.

    Good job, Keith, liked the extensive text and the test
