Experience: 1 Months


Worked Without any problem on the first try, worth to buy it so far
For me the price is abit high but well it is the buyers decision to decide wether to buy or not.
I heard that this thing is not that great.but for more i really like it. I think it was what i wanted to be.

Experience: 4 Days


Intel Chipset
oc'ing abilities
crossfire board
no sweet heatsinks(not really a weakness)
E8400 at 4.4ghz with pc2 6400 RAM, stable 24/7. For a budget I don't think it gets better than that!

Experience: 2 Weeks


lots of bios settings
cross fire board
none yet
paired it with a e8400 and overclocked it 600mhz to 3.6's stable and fast. really well built. I'm very happy with it

Experience: 10 Days


All the features - SATA2 + RAID, Sound, 2xGlan!!!, IEEE 1394
Only two pci-e slots.. But with so many standard features, I didn't use any of the pci-e slots
The mainboard is great, and for 124.99 deal it's a steal.. I paid much more for it.. I'm tired of gambling with technology, so I don't overclock - can't tell you if it's good or not for that.. Otherwise it's stable, works well with my psu and haven't seen any issues with it.
The best feature is that it has two gblan, no wireless though..

Experience: 1 Days


Nice look
Overclocking beast
EASY Setup
IDE Positioning
One of the best Motherboard for this price. Crossfire support (x8/x8) + 45nm Support + DDR2 1200Mhz.Easy installation, no screws inside the package and the 8-pin cable to power the motherboard is NOT include in the box !
The only downside is the positioning of the IDE connector at the bottom right of the motherboard.

Experience: 6 Days


My first build ever, this board was great, manual was sufficient for a newbie like me, everything labled well on the board, OCed E8400 to 3.915 easily with a couple bios changes
IDE connection at the bottom of the board? don't know its like that on most boards. also the power button, hdd led, power led were at the bottom and was a stretch for the wires in my case almost straining the cable to get it connected
Very good overall, positioning could be worked on, but its my first board so experience is slim. However the instructions were adequate as i got everything in and my first boot worked. the Bios for C1E needs to be turned off for any overclocking, because of its "gear" ability when i first boot my E8400 was only using a x6 multiplier and would go to x9 when stressed, so it could be good or bad for those who dont' need all the juice at all times

Comment: Good review of the Gigabyte GA-EP45-DS3R from Bit-Tech
Posted by: EmptySpaces @08/21/08
Comment: At this price, you can't go wrong if you're on a budget and really want a good quality motherboard. It's going to be really tough topping this one with anything else.
Posted by: Zenphic @08/20/08
Comment: In all, it's clearly not perfect but it does very well for itself in the meantime, so while we are adamant you can get precisely what you need given the ample variety on offer, if it does tick your boxes it should be a tempting proposition.
Posted by: Zenphic @08/20/08
Comment: The price is little below 100€ and Gigabyte GA-EP45-DS3R motherboard because of that and all other characteristics deserves our recommendation in form of InsideHW BestBuy Award!
