Building a Super Computer - I Need to take a Qx6850 to 4.8GHZ

[Hajpoj]

I don't want to use server parts.



I need the fastest possible configuration w/ OCing.

I Want to take a QX6850 to 4.8GHZ(533x9)

Can I get this with a P35 board + DDR3 1066 + Water Cooling?




Or a 680i board with 8800 Ultras x 3?

Maybe for a bit, but I highly doubt you could keep a 4.8GHZ chip stable. I honestly be suprised to even see it POST.

Why in the world would you not want to use server parts if you're trying to build a super computer. If you're looking for processing power dual Xeon's would be better.

 

[Hajpoj]

Because It needs to destroy games and server boards will limit me here.

 

[jpeyton]

Dell, Alienware, VoodooPC, AVADirect, etc.

Great places to blow $8k.

If you want to destroy games, overclock a Q6600 and pair it with a couple 8800s in SLI; should run you about $2k.

 

[Cutthroat]

You can destroy games with a 1 8800 Ultra and a Q6600 for less than $1000.

3x8800 Ultras is useless, you can only SLI two of them, and that's still overkill unless you wanna game on a huge monitor at insane resolutions.

Your money is better spent on a nice big monitor, a good gaming keyboard & mouse, your case, your cooling, speakers, etc.

Rig:

CPU: Intel Core 2 Quad Extreme QX6850 (~$1,200)
Case: Lian-Li case + VapoChill LS (~$1000)
[pick your P35 SLI board here] (~$300)
Water cooling for 8800 Ultras + chipset (~$300)
2x 8800 ULTRA [pick your model, maybe a more expensive already water cooled?] (~$1,600)
1KW PSU (~$300)
8gb ddr2-1066 mushkin (may need to use 2 sticks instead of 4 due to oc issues if any) (~$1,200)
2x150gb 10k rpm raid 1 (boot drive) (~$400)
5x500gb raid 5 (storage drive) (~$500 -- lots of deals around)
30" DELL LCD 2560x1600 (or pick your brand) ($1,000)

Total: $7,800

Vapochill LS is phase cooling, sub zero temperature CPU cooling. It can also be modified to work on a GPU as well.

I believe FrozenCPU.com had phase cooling that fit 2 GPUs and 1 CPU, but no longer sells this product.

Important note: don't buy DDR3 yet, because it's just not any faster due to cas latency (buy 2gb ddr3-1333 cas 7 for the price of 4gb ddr2-1066 cas 5)

Alternate suggestion (and probably way better if you're a gamer):

Buy a 3k pc w/ 8800 gtx sli and a quad core with a minor OC (3ghz maybe?)
+
a 2k TV
+
an xbox 360
+
a 30" dell 2560 for the PC

LOL, looks like the OP has been given the task by Intel to pull together a "consumer parts only rig" to compete with AMD's demo yesterday of a 3GHz Barcelona with 3x 2900XT's.

The "no server parts" requirement is pretty much standard requirement if the lawyer speak in the fine print is going to need to be able to say something to the effect that "this demo has been performed entirely by Intel with only widely available consumer hardware components."

I think a 4.8GHz overclock is possible with one of the quad extremes using the new B0 stepping if you have phase change cooling, but you're going to need very good cooling for the other components on the board as well. Unfortunately, nobody carries the phase change kit that supported an LGA775 + 2 GPUs anymore, so the best bet is going to be doing 4 separate water loops in your system with 1 for the cpu, using a water-cooled peltier, 1 for each gpu using a water-cooled peltier, and 1 for the nb, mosfet ect, using smaller watercooled peltiers with a standard waterblock on the RAM (cools the ram, then everything else). That should be able to bring temps down enough to /maybe/ hit 4.x on an extreme, especially since you can have generous use of multiplier to help. but basically a qx6800 + dual 8800GTX + DDR2 1066 4x1GB (Crucial Ballistix?), cool it as low as you can go and then see where things go from there. 4.8 is going to be really hard to hit without phase change able to cover all your components

 

[JackBurton]

Wait for the die shrink coming later this year and 4.8GHz should be much easier to hit. If you HAVE to have something now, you should be able to hit ~4.5GHz with a Q6600 and a VapoChill LS. Of course, there are no guarantees.

 

[JAG87]

you guys are completely insane.

you need dry ice or a cascade to take a qx6850 to 4.8 ghz. you might be able to do it with a heavily modded single stage phase change unit, that is tuned for load, and not temperature. if you think you can buy a stock phase change unit like a vapochill and overclock a quad to 4.8 Ghz, you are daydreaming. even if its a G0, it doenst matter the heat load is too much.

and either way, it wont be possible to run 24/7 stable at 4.8 Ghz. those numbers are just for quick benching, your cpu would never be stable at that speed. and it wouldn't last long either, because you need at least 1.7v to get 4.8 ghz. your cpu would be dead in a few months.

dont be foolish, set your bar lower or you will be disappointed. you should aim for something like 4.2 to 4.4 ghz with a vapochill unit. if you get it modded and tuned by someone who is experienced with phase change, you can squeeze 4.5 ghz. but thats about it. sure for benching you can go higher, but not for everyday use.



EDIT

here, this should give you an idea of what you are getting into.

an experienced overclocker like Fugger from XS can only get 4.8 ghz with 1.8v on his cherry picked QX6850 ES with his Chily1 modded Vapo LS, and even he says its not stable, 4.6 ghz is as far as you can go. and if you look at this sig, he runs his chip at 4.5Ghz for 24/7 operation. and you wanna do 4.8 Ghz with a random retail QX6850, and a stock vapochill LS. good luck buddy.

So you're saying it will go from like -20C all the way to over 70C by the time you get to like 4ghz?

 

[AmberClad]

Is this a joke thread? Or is the OP serious? Even if he's serious, there's more going on here than he's letting on...

 

[FrozenPie]

but, but, he wants to destroy games!

That can be done with a single GTX and any QX on stock, oh I suppose a second GTX and OC'd QX may be necessary for the super-zealots, but they're all nuts anyway

I agree, there's something here that the OP isn't telling us

JAG87 is correct, based on what i have seen over at xtremesystems, a good watercooling kit (I will be running my q6600 on a fuzion block, with my pa120.3 rad) might get to around 4 for benching purposes but not likely to be 24/7 stable. A vapochill would probably get you to 4 24/7 stable depending on your chip (and motherboard) but even that isint guaranteed and much over 4 is really pushing it. To hit 4.8 you are talking about a 100% overclock which is insane for a quad core. In terms of games, I dobut there are any games that wouldnt be gpu limited on quad once you got over 3.6 or so (maybe even lower), even with 8800gtx ultras (unless you are running at really low res) so 4.8 would be silly outside of holding some records.

i think your crazy, i think your crazy...

[Modelworks]

How many games are out that will make use of a quad core ?
Most don't even make use of a dual core.

With the current games you can overclock a single core cpu and see the same/near result.

 

[Rubycon]

This can destroy games with no problems and costs much less.

 

[GuitarDaddy]

You have about as much chance getting a QX6850 running 4.8ghz as you do getting a honda accord running 225mph.

And since games are 99% GPU limited, running a quad at 4.8ghz is as pointless as it is impossible. OP needs to come to gripes with reality and decide what the purpose of this build is
