With the extra copper claimed to have an effect on the cooling of the board, hopes were high that this could translate into better overclocking. Although we can't say for sure that it was the case, we did get some very decent numbers in our overclocking attempt, hitting a stable 480MHz. The board could even boot into 490MHz, though that failed to pass our stability tests. Compared to the majority of the boards that we have tested so far that failed to reach 480MHz using our processor, this Gigabyte board was already doing very well.
The other good thing about this board is Gigabyte's polished BIOS. Of course, this is not unique to the UD3P and can be found in other comparable Gigabyte boards but we felt that we had to mention it for the ease of use and features. While other brands may have more tweaking options, the ones we found were more than adequate for a mainstream board. Here are the OC related settings:-
We have only reviewed one other DDR2 board previously, the DFI LANParty DK P45-T2RS PLUS so it shall be our main comparison. Additionally, we have shown our results for the DDR3 versions of the P45 in our graphs. While we could only get our DDR2-1066 memory to run properly at DDR2-800 on the DFI board (for the lack of proper memory ratios), we did manage to get the Gigabyte to run at DDR2-1066 - but was running at a looser 5-5-5-15 memory timing instead. The following hardware configurations were used:-
The following benchmarks will be used to determine the performance of the Gigabyte GA-EP45-UD3P when compared to our previously tested Intel P45 boards:-
