754 pcix? 939 agp?

[Avenqer]

Hi just havent found anything clarifying this quite well so thought I'd ask in here.

A couple of weeks back, I read that the 754 socket cannot handle the PCIx 16x... and that a nForce4 board 939 socket cannot handle an AGP card at its max either... that it actual runs on two PCI buses instead...(!!!!)

Whats going on with this? can anyone verify this or at least point somewhere where they have benchmarked test to show that these transitions havent caused a good card to run sluggish?

Mainly, looking for two things:

1.) a 939 board that is nForce4 that has a AGP slot BUT will not hamper the cards performance/bandwidth.

2.) a 754 board that is nForce4 that has a PCIx 16x slot for graphic cards and again doesnt hamper performance/bandwidth.

Thank you ahead of time


Thanks

There are no nforce4 agp mobos, because the nforce4 chip does not support agp. If you want an agp s939 nforce board, you want an nforce3 ultra.
As far as nforce4 not handling pci-exp on s 754, there aren't enough boards out yet to support your claim.
If nforce4 supports pci-exp fine on s939, there is no reason why it would not work just as well on s754.

PCIe (PCI Express) is not the same thing as PCIx. PCIx is a workstation PCI slot - please don't confuse the two.

The socket has nothing to do with whether or not a mobo supports PCIe or AGP - that is a chipset dependent feature.

As Endyen said - nForce4 does not support AGP at this time. As far as I know, there are no s754 nForce chipsets that support PCIe.

Soltek's <A HREF="http://www.soltek.de/soltek/product/products_all.php?isbn_st=SL-K890Pro-754" target="_new">SL-K890Pro-754</A> is s754 with PCIe. It is based on the <A HREF="http://www.via.com.tw/en/products/chipsets/k8-series/k8t890/" target="_new">VIA K8T890</A> chipset that supports s754, s939 and s940. I personally do not like VIA...search for a recent motherboard thread for more info...

SiS has recently released the <A HREF="http://www.sis.com/products/sis756.htm" target="_new">SiS 756/965 chipset </A>combo that supports Athlon 64/FX/Opteron/Sempron (it supports s754/s939/s940, too).

So, there are two chipset options for s754 with PCIe: SiS756/965 and VIA K8T890. Of those two I would opt for SiS.

It's a chipset limittation, not a CPU limittation. The nForce3 supports AGP, the nForce4 supports PCI-Express.

The nForce3 can be made to work with Socket 939. The nForce4 can be made to work with Socket 754. But because both 939 and PCI-Express are newer, the availability of boards with 754/PCIe or 939/AGP is limitted to very few boards.

Nforce4 chipset has a "solution" around the AGP barrier. They call it an AGR slot which works for selected AGP cards.

That means nothing to me because it's not AGP. At best it's an AGP interface to a PCI-Express x2 pathway, but it could be using a PCI-Express x1 pathway. This is roughly equivalent to AGP2x and AGP1x performance.

You can get a few Socket 939 nForce3 boards, the nForce3 has an AGP controller where the nForce4 doesn't. Converting the other way, I've heard of an nForce4 Socket 939 board, but it didn't look like anything I'd buy.

Oh... great. Now, you'll have an simili AGP slot slowing down your videocard and you'll end up buying a PCIe videocard anyway, ... great upgrade path... Bravo!

-Always put the blame on you first, then on the hardware, UNLESS YOU HAVE A PROBLEM WITH A MSI BOARD !!!

*ROFLMAO* When I saw that, I thought: Holy Shiznit - when the Fock did THAT happen! Obviously ZZF has a little typo on their site...Let's take a look at Asus - they'll have the right chipset listed!









According to <A HREF="http://usa.asus.com/products/mb/socket754/k8n-e_d/overview.htm" target="_new">Asus</A> that board is using nForce3 255Gb.
















OOPS! There's a typo on that page...<A HREF="http://usa.asus.com/prog/spec.asp?m=K8N-E Deluxe&langs=09" target="_new">This</A> page actually states the proper chipset - nForce3 250Gb.















Bunch of FRIGGIN' KNUCKLHEADS!

I stand corrected. :redface: Interesting - it's not on the North American site. When will they be available for sale? Are they on pre-sale right now?

It's Asus.. they must be working on the BIOS hoping to fix some design flaws....

Or even design newer board... the longer you'll wait, better the should be
