Advantages of X38 over P35?

[iancarnage]

Besides the fact that some x38 run ddr3, what is the advantage of an x38 over p35?

 

[badge]

There are a few differences the most notable being X38 has PCIE 2.0 16 x 16 Crossfire capability and P35 does not. With DDR2 memory the two are pretty close in overall performance. I think when X38 was first released there was some talk P35 would not support the new 45nm quads, but that doesn't appear to be the case.

As badge said the main difference is PCI-E 2.0 (which doesnt have alot of difference with PCI-E 1.0) and also X38 supports CrossFire @ dual 16x mode

ASUS P35 boards support both 1333 FSB CPUs and also the next 1600FSB CPUs

so if u dont need CrossFire then P35 is a better buy

hmm.... yeah but im lazy. :0

In the time it took you to create this post at THG, you could have gone to INTEL.COM and found out for yourself in stead of finding someone else to do it for you? Get a clue people.

Yowza, at least you stay true to your name

lol..


Meh I went for P35, X38 not worth it imo. Reach higher max fsb by a little bit.

P35/X38 supports Crossfire, SLI is where you fall short (unless the obvious, there aren't 2+ PCI-express slots, of course). Does anyone know a place to find a BIOS or nVidia driver to allow SLI on this chipset? I have looked with no success, but its said they exist. Kind of like unicorns, cheap gas and fair taxes.

I have been thinking about going X38 with my new build.

Can it be confirmed that p35 will support the 45nm cpus, like the E8xxx? Have they updated their bios?

How far away into the future are graphics cards with PCIe 2.0? P35 wont support crossfire????

I only build a system every 2-3 years. I need as much future proof as i can afford. I would hate to be building another system in a year just because i need a new video card.

MrsBytch: i am lazy to. LOL. I like to hear from users with experience. Sometimes web-articles and factory websites have agendas. I will read those sites to, but a different outlook on a topic is always nice. Forums are great places for weeding out the marketing from real world.

yes, my ASUS P5K MB can support all the upcoming 45nm processors including the quads. Assume this is the same for other P35 based boards.

P35 supports crossfire but the second slot is not 16x mode. Currently cards have more bandwidth than they need by quite a margin at 1.0 if i'm not mistaken - shouldn't be a major issue.

I'd go with either a Gigabyte or ASUS P35 with DDR2 for best the best performance / price point.

P35 boards have what is usually advertised as two PCI-E 16 slots. Unfortunately, this is kind of shady wording; ONE of the slots runs at the "full speed" of 16x (sometimes called 'electrical') while the SECOND slot will only run at 4x speed/electrical. Huge difference there.

You can check around for reviews of 3850's in Crossfire on P35 and X38's. When on a P35, they are beaten by a single GTX (due to the 4x slot), but on X38 where BOTH slots run at full 16x electical, two 3850's are pretty much equal to the single GTX. Only now are we seeing that the 4x slots are bottlenecking cards.

Also just wanted to point out that some X38's support DDR2, some DDR3, and some even support both! I'd stick with DDR2 IMO for another year or two.

Just my 2 cents, but this DFI is an X38 and has a very good price. DFI is one of the best.

What?! There is a significant bandwidth difference between the two. Perhaps you worded it incorrectly.

The problem is that current video cards dont make use of the increased bandwidth YET.

The benefit of the X38 is that you will be ready when video cards are able to take advantage of that extra bandwidth. The big question is when.

 

[T8RR8R]

I think what he meant was that for current graphics cards PCIe2.0 doesn't do much for you over PCIe1.0. So there's really not much of a difference in performance...so far.

So I guess we're all on the same page now?

Someone else may know of some kind of hack, but no you cannot do SLI with an Intel chipset,it's Nvidia only.

Och, no kidding

...coming from a DFI owner...one might consider that biased... [:mousemonkey:2]

 

[T8RR8R]

Yeah I figured someone would put a checking on me about that, but people should look into that board it's great for the price. I mean ~$200 for an X38 board, plus DFI has almost always had a good wrap with Intel chipsets.

oops sorry i meant that for current cards the difference between PCI-E 2.0 and PCI-E 1.0 isnt much (like 8800GT)

I dunno I have yet have to see her post anything constructive. She flammed another thread and this was only the second time I have seen that name, quite a few posts though... But more than likely yes, lol that made me laugh.

 

[T8RR8R]

I guess I can't blame her because some people do ask some retarded questions that could be solved in about 2 minutes on their own, but at the same time I feel that is why I have the little X in the upper right hand corner of my screen. If I can't move a conversation forward and just want to e-choke some I just close up shop and go get a coffee or a toddy Comments like that just aren't really needed.

 

[sak33wa]

I doesn't matter. The only stupid question is the unasked one. otherwise no one would ever learn regardless if they're lazy or not. Judging by MrsBytch's join date... she'd be in her mid to late 40's, but I'm sure that with most women.. age and weight are exaggerated. And looking at a good many of her past posts (2400+) she was pretty helpful in the early days, though now a majority of her posts are bordering on flaming or chastising. I'm probably going to get flamed now, but hey... I'm married.. I'm used to it



Anyways... I'm working on building a new system as well. I've done some major research and had settled on the Asus MAXIMUS FORMULA Intel x38 mobo. Was wanting to aim at eventually going SLI, but seeing this thread.. will have to pull back and rethink on the mobo. Thanks

 

[T8RR8R]

I was just saying that if you don't like what someone writes down you don't have to reply even if you think the question/comment is dumb. I also agree that there are no stupid questions, just the ones not asked.

There is more heat being drawn up by Nvidia today than just the other day like this one for example http://www.fudzilla.com/index.php?option=com_content&task=view&id=6208&Itemid=1

If I were to ask most people in there 40s and 50s if they've heard of Intel most would probably say yes, but if I asked if they've heard of Nvidia most would say no. Just my 2 cents, and I've got a whole roll of quarters in my pocket.
