The "Waiting for Nehalem Mac Pros" thread

To tell the truth I haven't really taken a look at i7 coolers.

I assume you're not new to overclocking, but you've got to try to fry a chip these days. Also, One way to really kill the lifespan of the chip is raising the voltage. So I just OC as far as it will go with the stock voltage. However, I find that a slight under clock won't affect the OC potential too much, and will make the chip happier.

I've never smoked a CPU. Even with OCing. :)
Individual transistors are another story. :eek: :p

I also prefer to stick with stock voltages. :D

As far as coolers, I remember Zalman(?) having an issue in the past with the contact/mounting surface not being completely flat. Dished IIRC. Though I can hand lap one if needed, I'd rather not have to. ;)

I guess I need to take another look at available LGA1366 coolers available (or at least listed). :D I just don't want to try and use something that has too small a contact surface for the new package. To me, that's worse than too much thermal compound. ;)
 
It's fairly easy to see if the product is convex or concave as opposed to flat- usually I just return them until I get something close, then clean it up a little myself. I don't like lapping the CPU though, they're harder to sell later when you can't prove that it is what it is.

The only thing listed on Newegg is this. Garbage. Hell, just give me a 9500 with a bigger surface and the proper bracket.

I'd rather not have to return whatever cooler I end up with. It just seems like a major PITA.

As for lapping, I don't lap the CPU. Just the heatsink's contact surface, using glass or granite tile as a flat as a flat surface and very fine Emory cloth. (Wet).

"Noise Level At Duty Cycle 100%: 51.4dBA" No thanks. :p

So far, I've been looking at:
Noctua NH-U12P SE1366
Thermalright Ultra-120 eXtreme-1366RT (Maybe the HR-01 also).

Do you think the Zalman 9700 would fit on a dual socket board?
 
Off hand I think it has a 110mm fan. I remember seeing skulltrail builds with two of them, but those were 775. Frankly I think I'd actually like to use a smaller piece next time, the thing gets in the way of a bunch of cables, most importantly the 8 pin for the CPU. It takes about 20 minutes of fussing to get the thing off if I don't want to take off the heatsink. Hopefully they will think of some new way to secure it besides those damn back plates or even more damned push pins.

I know I could find out online, but I'd rather see for myself how memory overclocking works when the controller is on the chip instead of the board. I've never done anything with AMD, for some reason. I guess I got into the hardware side of things when Core was released.

Given the fact I use DP server boards, the size would likely result in not usable, unless they're staggered.

I'll assume they won't, and expect to need a 3 fan/2 HS sandwich configuration. The Noctua and Thermalright can do this, but I won't know enough details about clearance until the boards are at least reviewed. :(

Same here. ;)
 
The wait grows shorter. ;)

Kind of disappointed about the 5000 series launching in Q4 2009, I guess I'll have to make due with a 4870 for my next build :( :D

No, no, no. Sorry. I mean, from which product line is the X7400 from: Penryn or Nehalem?

Okay, that sheet says it's the 6-core one, so it's the Penryn that will never work in the Mac Pro?
Click to expand...

I think that the second number determines the series. So X7400 is Penryn and presumably the Nehalem part when it comes out will be X7500.

Similarly the X5570 is the Nehalem four-core that is the update to the
X54?? series that is in the current Mac Pro. The previous Mac Pro
used the X53?? series I think.

The first digit, i.e. the 7 or the 5 indicate the class of system.
The X7??? series are meant for 4 processors on a board, i.e. big and expensive servers, (I'm not an expert so may be wrong.)I guess the Mac Pro will always be a two processor system or perhaps a one processor system but is unlikely to move up to a four processor system as it would make it very expensive for not much gain for its core market.

Ah... The 7400 Series is definitely Penryn technology, and No, it won't work in a Mac Pro. It would require a completely different board. They'd also be way too expensive for most individuals, unless they had $$$ to burn and then some. A little insanity as well. :p

At this point, Apple doesn't seem to have any interest in producing a Quad CPU (MP) product whatsoever. Apple is sticking to a Dual CPU on the high end. I don't think there's enough market for them, and doubt we'll see one in the near future.

If the market changes however, who knows. :eek: ;)

I, for one, sure as heck hope that they don't change their minds and go with Beckton. In this economy, that'd be as crazy as Steve Jobs not doing a key...

Hmm...

I wouldn't worry. ;)

Apple's had Engineering Samples for some time I'd expect, and won't change this late in the game. :p

Engineering samples come out long before production starts.

Beat me to it. :p

@Tallest Skil:
Think of it this way: Without the Engineering Samples, how would system boards get done in time (approx anyway) in time for production? ;)

Figured they'd start boards once they had the chips (production run of chips) to build them around. Six to eight weeks is enough time to design an entire computer, right?

No. Not from scratch.

To go from a final prototype* to full production, has a typical lead time of 13 weeks, assuming there's no problems.

Getting it out the door on time is a matter of planning. And luck, as there's usually little room time wise for major issues. Otherwise, it either gets delayed or released in a premature state. :(

*Tested, and Approved for production. Level/thoroughness of testing not withstanding. ;) Quality Control is another issue. :eek:

"OK, so we have to design a board without the accompanying chip. Any questions??"

Why would they do that? It's a workstation, not a server. The clock speeds are significantly lower, and the price is much, much higher. That's one decision that Apple wouldn't make even if the 90's happened all over again.
