The motherboard or mainboard is the component that connects all the different parts of your computer. Often it has some integrated components like a sound card, enabling your computer to play sound, or a network card, to connect your computer to the network. The standard form factor (size) for motherboards is ATX, you need at least a midi-tower to fit one of those in. Micro-ATX motherboards are often more complete and have more onboard devices, like a video board and fit in smaller cases, but are generally less expandable.

The Gigabyte GA-EP45-DS4 is mostly well designed, with an accessible and comprehensive BIOS. However, theres only one PCI slot, which will be obscured if you use a second dual-slot graphics card.While overclocking the board was easy and resulted in a...

Il y a un peu plus dun mois le P45 était lancé officiellement par Intel. Après un premier comparatif nous allons étudier aujourdhui une carte de chez Gigabyte qui semble prometteuse. LEP45-DS4 intègre donc le P45 mais également le D.E.S. Advance un...
Bottom line Cette EP45-DS4 confirme notre première impression du P45 d’Intel : un très bon chipset, meilleur que le P35 qu’il remplace avantageusement, mais sans pour autant mériter un changement de carte mère. En effet si vous avez besoin de passer au Cr...

Bei unserem Muster des mit Intels brandneuen -Mittelklasse- handelt es sich um eine Vorabplatine (Revision 0.2) mit Beta-BIOS (F2B) - finale Aussagen zu Ausstattung, BIOS-Umfang oder -Potenzial sind daher noch nicht möglich. Auch die Kühlung wird bis...
Bottom line Der BIOS-Umfang ist hervorragend, das Übertaktungs-Potenzial der P45-Platine konnten wir aber leider noch nicht prüfen. Außerdem hat das EP45-DS4 eine geringfügig höhere Leistungsaufnahme als der Vorgänger. Bei Super Pi erzielen EP45-DS4 und EP35-DS4 e...

Next Page » BIOS, power consumption, features, first impression Two Intel P45 boards arrived at our place today - you can find a lot of pictures here. Unfortunately we are only allowed to keep the Gigabyte board for just a single day. Because of the sh...
Bottom line The new BIOS is great, but unfortunately we were not able to test the overclocking behaviour of P45 with our test sample. Furthermore the EP45-DS4 has a little higher power consumtion than its predecessor, the EP35-DS4. The performance of the two chips...

Til å være et hovedkort til under tusenlappen hos de rimeligste forhandlerne, blir vi svært godt fornøde med Gigabytes GA-EP45-DS4. Som navnet tilsier er hovedkortet basert på Intel P45-brikkesett, som generelt vil være det brikkesettet som er mest akt...
Bottom line I tillegg til testingen har undertegnede i over en måned benyttet Gigabyte GA-EP45-DS4 i sin egen pc, og kortet har fungert upåklagelig, og dette med en relativt moderat overklokking av prosessor og minne. Kombinasjonen pris, grunnfunksjonalitet og e...
