Which of these motherboards is better? :bounce:

 

ASUS P7P55D Premium

 

http://www.asus.com/product.aspx?P [...] templete=2

 

OR

 

Gigabyte GA-P55A-UD4

 

http://www.gigabyte.com.tw/Product [...] uctID=3239

 


From what I know, both of them support USB 3.0 and SATA 3 (SATA 6GB/S).

 

I heard that ASUS P7P55D Premium would require PLX PEX add on card to run SATA 3 Hard disk on its motherboard since the first generation PCIe x1's bandwidth would bottleneck SATA3's speed so using only Marvel chip would not guarantee the best solution for SATA3 to run on a P55 motherboard and PLX PEX add on card is a requirement.

 

For Gigabyte GA-P55-UD4, I don't know whether it also need a PLX PEX add on card to make SATA3 HDD run or not...

 

If there is something that I am missing then please tell me.

 

Thanks.

I'm interested in all this as well, since I'm postponing my new I5 build until P55A hits the market. Wanted to go with Gigabyte P55A. However, today I came across this thread:

 

http://www.ocforums.com/showthread.php?t=623288

 

and then checked the specs on Gigabyte site:

 

"* When set Turbo SATA3 / USB3.0 (Marvell 9128 /NEC USB 3.0 Controller) to enable in BIOS setup, 1st PCIex16 slot will run at x8 bandwidth and 2nd PCIex16 slot will be disabled."

 


So I'm much closer to getting regular P55 now, and upgrading to SATA/USB3 in the future when there is actual need for it.

Thanks for that interesting link.

 

Wow! I did not know that Gigabyte did not tell us about the impact on PCe x16 slot by SATA 3 and USB 3.0. That sucks... This means that you can run a video card on 1 PCIe x16 at only x8 mode when you are using SATA 3 and USB 3.0. :ouch:

 

They are using SATA 3 and USB 3.0 as marketing hype to sell their motherboards without telling us its negative side.

 

What about ASUS P7P55D Premium? ASUS did mentioned about the add-on card like the PLX PEX card which would enable USB 3.0 and SATA 3 and avoiding the bottleneck by PCIe x1 1st generation's speed (250mb/s). Would that prevent the PCIe X16 slot's bandwidth from being bottleneck to x8 mode??? :o

 

Would an add-on PLX PEX card also work on an ordinary P55 motherboard that does not support SATA 3 and USB 3.0????

interesting indeed. the usb3/sata6 was why i was postponing my 1156 build as well... why does it seems like 1156 always has some drawback? bad sockets first and now usb3 and sata6 for the price of a pci-e lane...

Both of these boards here are shown on newegg with foxconn sockets

Weather you overclock or not there is still a problem with foxconn socket.

the p55A ud4 and the p7p55d premiun are not even on newegg page, Those that are on newegg are the normal P55 no A ud4 and the p7p55d. They will only hit the market in mid november or maybe december. The new P55 A Ud4 have lotes socket. I dunno about the asus one. Even on the advertising page of the new accelerated line of gigabyte they talk about the new mobo using lotes socket because of the burning foxconn due to extreme overclocking.

Two Gigabyte P55A boards (UD6 and UD4P) are now listed on NewEgg: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=ga-p55a

Buying a mobo that is ready for USB 3.0 makes sense to me (it's planning ahead). Releasing a USB 3.0 capable board, but with other significant drawbacks that will no doubt be fixed in the near future (or may even have a fix now) is standard planned obsolescence. :pfff:
