Which 890FX mobo?

post #1 of 8
Thread Starter 
So right now my sig rig is one I will be ordering arts for soon, but I am still a bit indesicive on the mobo. The UD5 is probably what I'm going for, but saving money is nice. Once i get this system im going to try to overclock to at least 4ghz, so I'd like to have an 8+2 phase mobo, but is that really necessary? It'd be nice to save $70 and grab the biostar, but I am worried about exploding the 4+1 system. Also I have been considering the ASUS M4A89TD PRO, but that has 6+2 power. So, Is it worth spending the extra money to get 8+2, or are the other ones O.K. for 4 ghz + OCs on a thuban?

Biostar 890FX is one of the best overclocking boards on the market today.

True..... But its got a con that annoys some people.

The two Graphics slots on biostar board are very close, and in crossfire, cards get damn close. If the cards are big then the chance of the 1st slot overheating is high, since there is barely any space between the two and fan is pretty useless !

i had the same concern before buying the ta890fxe (it's 6+2, instead of 8+2)

but im running my 1090t at 4.2ghz/3.0ghz NB no problem.. can probably go higher... it's an excellent mobo for the price (~$110)

6+1 or 8+2 power phase only really matters when you are under extreme cool or extreme ocing(like 5.0ghz+).

Just be warned that the UD5 has the same problem as the Biostar board in regards to the PCIe slots. If you want x16/x16, the 2 GPU's will be right next to each other, so the first GPU will run a lot hotter than the 2nd. You can space the cards out be running one in an x16 slot and the other in an x4 slot, which is what I did since I've got measly 2900XT's and the extra bandwidth won't matter, but if you're running newer cards this might be a problem.

The M4A89TD Pro and the ASRock 890FX Deluxe4 both have PCIe x16 slots that are spaced further out, though.

I would look at the ASUS M4A89TD PRO/USB3 mobo. Good overclocking board and the X16 slots are well spaced apart.
