View Full Version : 3/5 X48 Motherboards on newegg support ddr2 only

My previous understanding was that x48 would be ddr3 p45 would be ddr2, like 780i/790i. But from the looks of it right now, it's not going to turn out that way at all. Newegg has 5 x48 motherboards listed, 3 of them(dfi, asus, gigabyte) having ddr2 support only. With the only two motherboards being ddr3 only(ausu gigabyte).

So wtf?

I can show you why in three links: Exhibit A (http://www.ebuyer.com/product/128496) - Exhibit B (http://www.ebuyer.com/product/129954)- Exhibit C (http://www.anandtech.com/memory/showdoc.aspx?i=2989&p=7)

When DDR3 offers more than a 3% improvement in performance for less than 10x the price of DDR2, it might take off. Until then though, I wouldn't count on it being anything of a minority's minority product. And even then, one only bought by the most exceptionally deluded of consumers.

I wouldn't be smiling Mr. 6 1/8", I hate to tell you, but thats not to impressive....

Back on topic: Intel originally said that x48 would be ddr3 and p45 would be ddr2, that would be their only differnce, so I'm confused about why there are x48's with ddr2

No, that's not the difference between those two chipsets. Both are DDR3 products.
The P45 has a different PCIe configuration, 2x8 lanes for CF for example. Plus it will have the new southbridge (ICH10).
x48 daul 16x
P45 16x/2 (8x and 8x)

You won't see an performance differences between 8x and 8x or saul 16. None of the current cards require that much bandwith.

they use the same 65nm NB and ICH10R southbridge....

I can't see any differences between them that will be noticeable in game play/benchmarking.

Gigabyte, dfi, and asus have gone on record at cenit saying that they are not planning to come out with a p45ddr3 capable chipset, thats why I thought that x48=ddr3 p45=dr2.
