Nf3 ultra all have working 5x ht :)

So this flaw only applies to NF4 boards and NOT NF4 Ultras and NF4 SLIs? Or is this the case across all NF4 platforms?

Someone correct me if I am wrong but I believe it affects HTT (AMD's FSB per se).

HTT is basically the fsbx the multiplier, and yes it would affect every nf4 mobo made with a01 and a02 silicon (SLI wont be made for a little while longer so all SLI boards will probably be made with a03 silicon).

How would one determine which silicon level a board is at? Is there no way to tell without checking the board visibly?

Like many others I'm trying to hold out for the NF4 but if we purchase from New Egg or another online retailer will we even have the opportunity to find out if it's A01, A02, A03 etc...this is a definite concern based on the inquirer article.

:confused:

Not to debunk anyone's forum thread, but...everything you read on the inquirer should be taken with a grain of salt until you find info elsewhere to back it up. Just a snack to munch on...

Yeah, but, most of the technical information, especially if they get it directly from the vendor, is generally pretty accurate.

FYI, I emailed the auther at theinquirer, and asked him to show the "official" document referred to, and he refused. That seems a bit suspect to me. Anyways, I agree with Pohemi420, especially considering every single website that has reviewed the chipset so far has failed to mention anything about that, and I would think that is something that somebody would have noticed by now. Besides, I don't think nVidia would do this, considering that they don't have any real competition right now. At the original A64 launch, they had to get the NF3 150 out the door to compete with the K8T800, so they had to make do with 600MHz HTT. Now, the only thing that has been launched is the vanilla K8T890, which sucks, and it's just a paper launch, nobody shows any signs of actaully having them available any time soon (Abit announced theirs over a month ago, but shows no signs of availability any time soon). If this was a big problem, they would have just waited, or gone ahead and released a NF4 150 with a slower bus, promising the full faster 250 version later on. I'll believe it when another website corroborates the story, using something other than the inquirer article as evidence.

Very tasty snack Pohemi420. Too much information out there for it all to be reliable or true. However Intel didn't exactly get PCIe right either. If you recall they had problems with the initial rev of the "Lindenhurst" chipset for the new XEON's. It has since been resolved but there are production boards in customers hands that will not support certain PCIe cards. I would hate to fork over 150 -200 $$$ for a tainted NF4 board, especially after waiting so long.

I'm definitely gonna wait for some sites to review the first nF4 boards, but if they all seem to think everything's kosher, then I'm certainly not gonna freak out because of something the inquirer said and refused to show any evidence for (i'm still waiting to see that magical document they refuse to show us)

You are forgeting, when the Inquirer is wrong who is the first to point it out? The Inquirer is always first to admit they goofed. Seriously they have been pretty good with giving us the info accurately.

THG just posted a reivew roundup that included both the ASUS and MSI NF4 boards.

The reivew never mentioned any problem with the NF4 chipset and HTT multipliers, and those two boards performed about the same as every other board they tested.

I am extremely skeptical regarding the INQ's report. My feeling is that the definitely deserve their name.

Hopefully they are wrong about this, but there's a first time for everything :)

EDIT: I suck, just noted the original date of the posts. However, perhaps we can agree that the INQ was wrong about this, since it doesn't seemed to have panned out the way they said?

-D'oh!

Well, all nForce4 boards on THG's latest article are either Ultra or SLI. that means it's an A03 core that has no issues hitting 1000MHz HTT.

Instead of throwing older revisions of the chip, nVidia is marketing them as nForce4 4X - this is a stripped down version, lacking most features and seem to run stable at a maximum HTT speed of 800MHz. Still, people have been able to hit ~900MHz with it, but not the golden 1000MHz...

I think the K8NF-9, than sports the A02 core is a good buy for anyone looking for the best bang for the buck ATM. the Chaintech board with the nForce4 Ultra A03 core is quite problematic according to a quick search I made here, while the K8NF-9 has been trouble-free so far. just my 2c.

Running in 3x, 4x, or 5x Hypertransporrt results in about a 1% performance difference. Insignificant. This is just like everyone thinking AGP 8X and PCI Express makes a difference in performance when there is absoultely no gain for either of those two over AGP 4X right now.

Sorry, but looks like a lot of people swallowed the marketing bait whole hog.
