That sounds like a Very Bad Idea (tm). Just use your two 6-pin connectors and you'll be fine. (Unless you have a pathological need to overclock).

May I ask why it's a Very bad Idea? If it's recommended with both why not do so?

Indeed, didn't come as a surprise to me.

Where can I get an operating system, that is Vista ready? :wink:

Nope that a motherboard adapter.

Er, WinXP with DX10 (somehow). :wink:

What you're basically suggesting is that the ring is not only used for memory traffic, but also for other intra-chip communication. It's possible. But the closer you get to the theoretical maximum BW of a ring, the harder it becomes to avoid freak behavior. (Including the possibility of a deadlock.)
If you have a few hours of free time, you should try once to model a ring with a scripting language and see how it behaves as you increase its utilization. The spread in latency goes through the roof.

If they're using it for other stuff than just MC traffic, they need all the smarts they can get!

I don't know about you, but I see crossbars between those clients.

I did say in that post that there are advantages and disadvantages in either topology. I said nothing about what goes through the ring, beats me.

Maybe I should put it in other words:

This chip is sufficiently complex and can have features that help it overcome the issues of a ring topology.

There is no way with the information you know right now(which amount to close to nothing) to just call this design decision as plain bad...

Maybe I misinterpret you, if so sorry and would you care to clarify your point?

About the PSU, here

In other news, AMD released a AMD GPU Clock Tool to reviewers. It works with RV630, RV610 and all previous AMD products too.

And a couple of posts from Shamino..

Confirming the MSRP
On Fuad's story of R600 cooler reaching 100C

The PSUgate is a non-story. I think nicolasb nailed it - AMD is just trying to cover all the no-name, 2-lb PSUs out there. I seem to remember a 100W+ gap between PSU Nvidia recommended for 6800 and the one most people could run it with. NBD.

Remember how everybody was freaking out big time about the dual power connectors of the 6800U and the OMGLOLHUEG 480W official PSU recommendation? This is basically round two... sure, the numbers are different but what it boils down to seems the same to me - if you're even *thinking* about dropping one of these in your box, chances are, you're current PSU is powerful enough already.

So... what he said.

In fact, NV40 is quite hungry...

G70 is specified to require a bigger PSU but draws about the same (GTX vs Ultra), the same goes for the G71.

All this BS about PSU requirement wouldn't have been a problem if some fools didn't marketed the "German engineered" and such overestimated and even underprotected PSUs. (some don't even meet european standards, but given no one complains about that they don't worry about their self-claimed compliance)

Real HD 2900XT temperatures?

Perhaps think of it as a fibre ring.... Just instead of going around a small town, it goes around the chip.

According to this page (a few days old) AMD will skip the 80nm, quite confusing when everyone write different things:shock: .

I'll keep an eye on this thread over at xs.

The "OC masters" have their cards now, and hopefully one of them will get drunk and talk to much. :lol:

Edit: Wee! My 600th post. I'm such a spammer.

Depends on your POV. For noise-conscious people like me, energy efficiency is a big deal. And it looks like NVidia wins big time in that department.

What's there to complain about, the only news from people that actually have the card and are under NDA state that it's pretty much as quiet as a 8800 GTX idle and under load.

Myself, I'm planning on running one in my shuttle case with a 450 watt PSU.

I seriously wouldn't be surprised if this could run on a modest system with a core 2 duo, 1 HD, and a high quality 350 watt PSU, assuming they even sell PSU's that low with 2x6 pin connectors.

Unless of course the Vista 64 drivers suck in which case it might still be a toss up between this and a 8800 GTX. Still a 399 USD price point is mighty attractive.

Still, if the card can really draw 200 W or more, there will be a very significant number of potential buyers with PSUs on the weak side. The question is not if AMD will lose sales, it's how many.

It's also part of the reason the card is so cheap. You can buy new psu AND HD2900XT, for the cost of the competitor's product.:lol: I understand that part of the reason 8800U is so expensive is the high-grade ram, and the AMT of it, but it then also strikes me as good reason for there to NOT be an XTX card w/ 1gb of ram, or AMD would not be able to release the card for so cheap. The GDDR used on these AMD cards is not so expensive as the memory on nV's cards, but 1GB of GDDR4 is a whole different story!

Sure, that's not that unusual with high-end parts. The length of 8800 GTX no doubt lost some sales (or at least moved them to GTS) as well.
