No, it doesn't. The Intel 5400 Northbridge only supports FB-DDR2. If you try to use unbuffered DDR2 it won't work at all.
ok,seriously? i have no frigging idea how i missed the FB bit time and time again x.x . . ok, that pretty much nixes the whole idea of this system . .

Not that I know of, but I'm not entirely up to date on Vista utilities. Generally, the OS schedules threads in a process that is totally transparent to the user. A programmer can write his program to only use specific cores, but this is generally a bad idea because it interferes with the OS's scheduling ability and is, again, totally transparent to the user.
i know some codermonkeys and guys with the whole cisco and microshit certified batch in their resume, and consens was more or less, that it would not be all that hard to tell the system which cores to use for what . . but now this point is moot anyway . .
QUOTE
Actually no. The Core 2 Quads are made of two separate dies dual-core attached to the same package. Each die has 6MB of L2 and cores from one die cannot use L2 from another. That sort of setup will net you 12 MB of L2, at best, which you could also get from a single-processor setup. More importantly, doing so defeats the entire point of having a huge shared L2, the ability of multiple cores to operate on the same data at the same time. If you do what you suggest, you just have the same data duplicated twice on two different caches, more likely than not . Furthermore, the fact that the two processors have to communicate with each other over the Northbridge introduces some extra latency into the process.
i may be misunderstanding something here, but as far as i remember, the Xeon are not 2 separate dies . . will have to check up on that . . or not, now that this system will probably not be built <.< . .

If you just have it lying around, that's different.
technically speaking i have a complete computer in the shelf behind me . . just not compatible parts *snickers*

Then get a motherboard that doesn't require DDR3.
Or, better yet, get a Core i7 920. The performance difference between the Core i7 and the Core 2 is absurdly huge, due to the i7s onboard memory controller, improved cache, and single die construction, among other things. It won't help much with gaming, but it will with everything else.
ASUS Striker II Extreme nForce790i Ultra SLI MB supports Core2Quad and Penryn CPU's with an FSB of 1600MHz and DDR3 with 1333MHz and up to PC3-16000RAM with 2 unbuffered Channels. . if that's the whole bottleneck, the bottle is big enough anyway or am i misinterpreting soething there? on this board there will only be 4 Gigs of RAM, not more i think . .
and 3-Way-SLI with the 3xPCIe x16 Slots sounds nice enough for future upgrading options i think O.o
or just usual SLI and an Phys-X Expansion Card maybe . .
QUOTE
That's sort of true, but you're still going to be stuck with fully buffered RAM and an extra processor won't provide any significant performance boost.
ok, the Oktav will not be built anymore anyway now <.<
QUOTE
Well, you did miss the FB-DDR2 issue. That's a biggie.
Well, that's a good reason for a multi-processor system, I guess. It really depends on what sort of video encoding program you're using. Assuming that it can take advantage of four or more cores, such a system will be slightly better than an i7 920 based system
yes yes,i don't know how i missed that again and again ._.
and i don't really understand what all the ruckus is about with the Core i7 . . especially since those will exclusively use DDR3 RAM and not DDR2 RAM . . and in price/performance they don't come close to the Core2Quad with 3GHz right now O.o
even right now, the Core2Quad with 4x3GHz costs about 500 to 550 bucks and the i7 with 4x2,93Ghz costs 700 bucks . . the 4x3,2GHz costs 1200 bucks, which is about 4 fitfths of the price of a whole new system after my specifications . . and only 8Megs of Level3 cacheand not even one MB of Level2 Cache? and the Hyper-Threading coming back does not give that mcuh more power too . . only thing that seems like about 50% better is instead of 2 there are 3 RAM Channels . .
i'll have to look deeper into this. i somewhere heard something about 8 virtual cores and am questioning the purpose and performance of this . . 8 virtual cores that have to share 8 Megs of Level3 Cache between them? can that compare with 4 REAL Cores and 12 Megs of Level 2 cache between the 4?
QUOTE
That's a good a reason as any, and better than most.
well, in the beginning it was 50% performance and 50% AssHole Computer . . Asshole Computer because it was basically just to show one of my a bit more obnixious and braggy buddies that his oh so cool machine with Core 2 Duo wasn't all that hot to begin with . . and that i would be able to build an about 2 to 4 times as strong system with about the same ammount of money . .
Later on came the realisation that i could do some serious work with this . . compiling bigger software projects for other buddies, to hardcore video encoding and image editing and the such . .
and when i saw that an Core2Quad System was more or less exactly as expansive as this 8-Core System but did not have as good a price/performance and upgradeability score i basically said fuck this noise, it's perfect, i am going to do this . .
QUOTE
That's a nice system, but I am going to point out that dual-channel DDR3 is pointless in Core 2 system. It's nice to have and all, but the FSB simply can't handle the bandwidth. With the FSB as a bottleneck, you might was well just use DDR2 at 800Mhz in a dual-channel configuration. You can't pump data through the Northbridge much faster than that. Or use a Core i7 with the DDR3, since it isn't limited by the Northbridge.
i repeat, with an FSB of 1600MHz and RAM of 1333MHz, is that such a tight bottleneck?

ATI's newest offering, the 4800X2, is actually slightly better than nVidia's SOTA card, sort of. The 4800 X2 provides better framerates at high resolution with heavy anti-aliasing that the GTX280 does while the GTX 280 is superior at lower resolutions and lighter anti-aliasing. The GTX 280 also performs better on XP, in general, while the 4800X2 performs better on Vista. And the 4800 X2 eats substantially more power than the GTX280 does, even on idle, due to less than ideal power management combined and its dual-processor design.
i just checked, and i can order ATI4870x2 with 2 Gigs of GDDR5 RAM . . the specifications sound nice enough, and the power consumption ain't that big of a point for me anyway . . i am planmning on using 1000Watts PSU in the new Machine anyway . . but as i said,i have the 8800GTX just hovering around here right now . . maybe i'll build the new system with the 8800 in it . . or if the prices fall after christmas i will look at this issue again . .
