1.4v being your goal for heat? I don't know. Maybe 3.2 to 3.4 I'm guessing. You should still be pretty happy with it even at 3GHz.

well, I can't really judge heat until I try it, I was thinking more of electronmigration. I'm willing to go up to maybe 1.42-1.43V something like that if I can.

As in power consumption?
I'd say you could still do 3.4GHz pretty easily. Especially seeing as it's just 2 E6600's slapped together.

No, as in electronmigration, frying the chip by giving it too much voltage.

for 65nm C2Q qith those types of coolers, IMO 1.525 is the sweet spot IICR for temps and OCability.
one guy has gotten his Q6600 to 4.0GHz on a P5K-E with a TRUE and 2 140mm DELTA fans :D sams favorite fans :) but it ran perfect. (albeit at 1.6 on the Vcore)

OH! lol
AFAIK, 1.5v seems to be about the safe limit. You could take it to 1.45v without problems. I've done it for months with a small heat increase but not much else.
At anything below 1.5, your main worry is keeping it cool. If you can keep it cool, which you Ultra 120 should do nicely, you need't worry about "frying" the chip.

Yeah, I'll probably pass on the 4Ghz thanks... haha, and the 1.5V, but 1.4ish and the mid threes I'm hoping for - essentially enough to give me a noticeable performance increase from my 3.2Ghz E4300 on two cores, whilst also having a quad core CPU, if you see what I mean.

eelctron migration really comes into play with a high VTT and PLL, not so much the Vcore

Even so, I'm not taking it high, especially as it looks like I might have to manually overclock. I'm hoping my mobo's hard limit of 368FSB won't affect the Q6600 too, if it does, maybe I'll have to resort to a BIOS flash.

Yeah. I'd think you could take it to just about anything you want with 1.42-1.43 or so. 3.4GHz is definitely an option.

Indeed, on auto my X38-DS4 seems to top out at 1.408V, and auto or otherwise, it won't let me go above 368mhz FSB, so I may have to look into that.

You honestly shouldn't be letting it stay on auto to begin with. The X38s are supposed to be awesome overclockers but no motherboard OCs well on auto. The auto values given are usually far below the limits of the board and the CPU.
And only 368MHz? That motherboard is known for routinely going over 450MHz(or is it a CPU limit?). Try a BIOS flash and see if that helps. I specifically looked for that feature in reviews, and the one I'm getting should be fine. If that's not the case, Gigabyte's lower end boards actually OC better than their higher end boards by a longshot.
As for voltage, anything in the 1.4-1.42v area should be perfectly safe if you use non conductive paste and keep it cool. I definitely prefer AS Ceramique for OCing over AS5. Even then, the Q9450 could do well over 3.4GHz at under 1.4v. So I would expect similar of a Q6600.

This shows the Q9450 on an X48 board. Notice the values they take it to.

No idea, bugs perhaps? I saw a post from ket0la the other day, a name I havent' seen for ages, and less than an hour after he made the post, it had 'suspended permanently' under his name...
edit: Ah, I see now. Too bad, if you don't play to the rules, you're out.
Indeed, I was thinking BIOS related for the OC - trouble is, Gigabyte boards like the X38-DS4 don't store BIOSes - i.e. if they ever hang at POST due to an overclock, they revert back to F1 again, and you have to flash them again...

Try a new processor then before you blame the board. Some boards I've seen will limit voltage and FSB options per-processor. I think a Q6600 might have quite a bit more headroom.

I certainly will, I have no intention of slinging my X38-DS4 any time soon. One point of note though, my HD4870X2 has arrived, and only fits in the bottom slot due to the size of the southbridge heatsink - even then it's a tight fit against something else, I'm not able to screw the card in...
Worthy of note for anyone contemplating HD4870X2 Crossfire X with an X38-DS4 or X48-DS4, I think they have the same lay out/

If it only fits in the bottom slot, you might have some heat problems. A few people have had to do that with the 3870X2 and had lots of overheating. Watch your temps. I think if you want to aim for low noise and heat, it might not work out. But we'll see :P
With the Thermaltake Armor I am confident I can fit any card I please. 2 4870s should definitely have no problem fitting. Though it's only going to be one for now.
When my parts get here, I'll report on my OC and game performance. I doubt the processor will be much of a step up for games but the video card should rock. I'm just excited because I'm expecting even better temps due to the 45nm process.
My major concern for the quad core is multi-tasking and the like. I can assign different programs to different cores. It's seriously annoying when my framerates in Crysis take a dive during a virus scan.
Also, if possible, I want to see if I can get all of my background processes to start up on cores 2 and 3 so I can use cores 0 and 1 solely for the applications at hand. That could prove interesting to try.

It's got nothing to do with the case, it's the board, and you have the same board I do. At the moment the X2 seems slower than the 4870 in every game I play, which is a disappointment, but then again, 8.8 is a bit of an obscure driver set, I may try 8.7 and see what happens with that. 3dmark is up above 14k, but real world gaming performance seems poor, still far better than the 3870, but not as good as the 4870 - notably the 8.8 has no option to disable crossfire?

Correction, I will have the same board you do. lol
So it doesn't fit well on the X38 eh? Glad I didn't even think about getting one then :P I'm not one for those dual chip cards anyway. If the game doesn't support crossfire, it is actually a bit slower than the single card. That plus the size, plus the heat, plus compatibility issues with certain boards...
My advice would be to send back the 4870X2, keep your current 4870, and do crossfire if you must have a dual card setup. I'm not even sure if I want crossfire with the 4870. It's just nice to have the option.
Different drivers might sort that out, but you might have to wait for 8.9... I'm not really up to date on any sort of video drivers so don't take my word for it, lol. I just use the latest ones available.

Yeah, wise. - the trouble is, the X38-DS4's southbridge heatsink is TINY, it may as well not even be there, so I reckon any other board with southbridge anywhere but miles away will have the same problem...

That sounds almost dangerous. Look out for black burn marks on your card if it's touching the heatsinks. I've done it with the X800GTO on my ASUS A8N-E(one of a few excellent ASUS boards). Edit: I'm thinking... is the southbridge even a worry? I thought the northbridge was the main concern for heat. AFAIK, the southbridge is the integrated sound and NIC. Though, I could be wrong... I'm no expert on motherboards :P
Dual chip cards are cool, and the HD4870X2 is faster than a GTX280, but they're not dependable or realistic in any average enthusiast system such as yours. You should wait for price drops on the HD4870 and just go crossfire like I plan to. I wanted to compare FPS anyway, lol. You almost made me cry when you got that 4870X2(not really).
Oh well, don't mind me right now. I'm a tiny bit drunk, LOL XD

Correct, my P5N-E didn't even sink the southbridge and the NB was twice as hot as the SB.
Will do more testing before calling - Crysis performance was good.

It may take a few new drivers and patches to improve game support. I'd still expect it to work on quite a few games just fine. How are the temps?

Absolutely fine, but CF works so rarely they're hard to test. When Crossfire fails (i.e. requiring a restart to re-enable) it also seems to take powerplay with it, so not only are you using one core not two, you're using one clocked at 500mhz not 750 - that might explain the performance drops. The card is idling at 69/51, far lower than most report.
Additionally, Overdrive only uses 40% GPU usage?
The 4870X2 also seems to reintroduce the DirectDraw bugs present with the 3870, albeit not quite so severe, and on top of all that gives zero gain in the vast majority of titles... Crysis is one of the very few games that does work. The figures from benchmarks of reliable frame rates of 80 plus at top settings are complete lies - Crossfire is every bit as much of a pain in the arse as it ever was, and realistically is far more trouble than it's worth.

Cool, but keep an eye on the temps.
My point exactly, the individual chips are clocked lower than a stock 4870. So if crossfire doesn't work, you have more like a GTX260 than a 4870. As you've said: the speed of a single card is guaranteed. So I'm hopeful that a single card will be sufficient for my needs. And after those test runs you ran, I think it will be. All high in Crysis at 1920 x 1200 is for me :P

I think there could be some improvement in the drivers. I seem to remember seeing that a lot in reviews of the 3870X2. Then new drivers came out and it was awesome.

Don't forget, if that wasn't enough, the card takes c. 15 minutes to install in most cases due to the tight fit, and does not fit in a standard motherboard layout securely, you have to leave it hanging out slightly... I have checked and the card is not obstructed, the front part of the PCIe connector simply does not go down all the way, so you can't screw the card in.
Based on all this, I strongly urge those considering an HD4870X2 to have a rethink. The HD4870 is completely bug free, performs solidly and is more than adequate for most people. The HD4870X2 is just pain and suffering for minimal gains (45 to 60fps in Half life, not 45 to 85, and 12 to 14 in the harshest bits of crysis) in minimal number of titles (FEAR and Age of Conan non-working, despite benchmarks saying otherwise). I realise part of this is my CPU, but other than 3dmark06 there is not a single game I play that owning the X2 has affected playability-wise in the slightest. GRiD runs with 4xAA but the frame rate is still very low. In benches it's advertised as 94fps. I get around 25.
