Impressive. Yeah, I need to switch back to AHCI mode. I tried doing it without re-installing windows, but I can't seem to get that going. Looks like it's back to the install disk again.

Oh, and here's CDM being run on the System Disk 840Pro with your settings for comparison. I use a 300GB partition on the 840Pro for capturing video as its standard application. The system partition (C: Drive) is 108GB, and the rest is set aside for OP. As you can see, the standard 840 holds...

Uh, okay. Just downloaded it. This is running on a Gigabyte GA-Z77X-UP4, with a 3770K CPU @ 4.0GHz, using the Intel RAID controller in JBOD configuration (ie. not AHCI, and no actual RAID being employed). This is the 500GB Samsung 840 drive being measured here. I set my partition size to...

I picked up a 500GB Samsung 840 yesterday. I also have a 512GB 840Pro as a system disk. I used to have my games on a 240GB Intel 520, but have since moved them (Steam & Origin) to the 840, and subjectively noticed no difference. The 500GB 840 doesn't write as quickly as the Intel 520, but a...

Ok, got it all sorted now. Thank you for the help. The HDMI wasn't working, because I had selected to display just to the Samsung. I then tried to do extended displays, but couldn't get the 2560x1440 res on the Samsung. I finally managed to figure out the correct sequence to do it all in...

Mate, thank you so much. That was it exactly! Been driving me nuts, and it was as simple as that. I kept moving the mouse, moving, moving, and eventually the pointer showed up on screen. Clicked to set the resolution, and got the displays to select. Set it to the Samsung as the main, and...

That's hard to test. I've currently got audio working via SPD/IF to the receiver for compressed surround sound decode. If I start up anything that plays sound, before plugging in the HDMI to the receiver, then the sound source is already bound to the SPD/IF output, and so it doesn't switch...

Thanks for your response. Yes, I've tried loading Windows without the receiver HDMI plugged in, and then plug it in. As in the OP, as soon as I plug the receiver HDMI in, all I see is the desktop background, and nothing else, in 1920x1080 subsetted within the 2560x1440 frame (ie. desktop...

Thank you for the reply. The DVI is definitely the primary, or at least I think it is, because when I boot up, it's all working fine. It seems to be as soon as the windows drivers load is when it goes haywire. Yeah, I tried from GPU to receiver to monitor, and no go. Receiver is actually...

Ok guys, I got a bit of an odd one, and I've not been able to find an answer. I have a Radeon 7970 video card, and previously was driving my old 1920x1200 monitor with a dual-link DVI cable, and driving a surround sound system with an HDMI cable plugged into the HDMI out of the video card...

In a nutshell, it was found that various of their data points for their own radiator are physically impossible. Placing trust in the rest of their results and diatribe at your own peril. Brass radiators actually do use all-copper fins. The impact of the brass used in the very thin tube-wall...

No, but I do reckon that there's enough out on the web in the form of myths about watercooling that there'd easily be enough material to base a one season show on. Hmmm. I have a decent little solid state camera that puts out near DVD quality images. That's a thought. Could start doing...

I have an 80mm radiator here (MCR80-QP). Not a double mind you. Next time I run a round of tests (coming up shortly), I'll whack it onto the testbed with some decent 80mm fans and doing noise vs performance tests. The issue I have with sweeping statements is that for ages now people have...

Yes - gotta be picky about the fans. A pair of Panaflo FBA08A12L fans on each side of the radiator would yield decent results with the lowest noise.

As did I. I just wanted to ensure that we weren't dismissing the dual 80mm rad as junk for all scenarios. It is far from such.

Thanks for taking the time to qualify your response. See, I was responding to this statement by you: I'm glad that you took the time to qualify your statement further, rather than issuing a blanket statement that is in fact, incorrect. We can use a double 80mm radiator in any scenario where...

Don't know why the prejudice. 8x8cm = 64cm² => 128cm² of radiator area for 2 x 80mm rads 12x12cm = 144cm² of surface area. Dual 80mm rad has 90% of the surface area of a single 120mm rad. 80mm fans have really good pressure to push through restriction. They're typically quite a bit better at...

At 400W heat load, 0.05C/W => ~20C water temps above ambient. The dual-80mm rad could therefore handle that heat load, although the water will be getting pretty warm (40-50C or ~100-120F). It'd be fairly borderline as to if water or air would be doing a better job, but if you consider it as...

80mm rad, blue curve is a 31dBA fan 120mm rad, a 34dBA fan is the solid blue line. 2 x 31dBA fans = 1 x 34dBA fan noise wise. 2 x 80mm rads @ 1.5gpm => ~0.05C/W 1 x 120mm rad @ 1.5gpm => ~0.055C/W Looks to me that noise-for-noise, pound-per-pound, that dual 80mm rads is a touch better...

Ran through various scenarios, and it doesn't really matter (to within ~0.1C) whether the radiators are in liquid-flow series or parallel. Depending on specific circumstances it can swing one way or the other, but rarely does it differ by more than 0.1C either way. Just route it however is...

Yep, this has been precisely my thinking for a while now. So long as we're above 4LPM (1.1gpm), the differences get smaller, fast. Past 6LPM, pretty much all gains are so negligible as to be not worth the bother (IMO). Couple that with the pump heat dump from the more powerful pumps to push...

Heck, for a while there I ran my entire water-cooling system off a $5 pump the local hardware store. It was 1.5"x1.5"x1" in size. Tiny thing. Put out around 3lpm peak, and had about 50cm of pressure head. I barely noticed any difference. CPU overclocked 30MHz lower, temps were 3C higher...

It's no misconception that all blocks benefit from more flow. The Procooling tests, which were run on an actual CPU on a real motherboard running real load, which is why the tests were so popular, demonstrated that all blocks benefitted from more flow. More flow equals a cooler CPU. Reference...

The "impact of flow" is what has been explored all along with flow vs performance graphs being conducted by various reviewers. It WAS the first chapter, and it WAS the first thing done. What has occurred since, at least to my eyes, is an incredible inability to actually use that useful data...

Who is doing the math I ask? I did the math over at XS, and found that the impact of an elbow would be significantly less than 0.1C per elbow. Are you sure that math/theory was actually used, or whether or not people were just talking out their rear ends? Perhaps this is the issue. People...

No. Local. Frictional resistance is a factor, yes, but since we can't create from energy we don't have, there is a limit to your statement. Even a Laing DDC2 only pushes without around 3W of hydraulic power. What that means is that no more than 3W of power would get converted to heat in...

I did state that I was primarily talking about the Maze 4. You're wanting to drag this back to the Maze 3, presumably because my 5-10x statement doesn't quite hold true to that block, and you feel that you've "got me" on that one. Okay, fine. I'm not going to argue it any longer. This is not...

You could still mount the WW on a S775, if you placed a 1.25" x 1.25" x 1/8" thick copper shim between the CPU and the waterblock base. This would raise the block up high enough to clear the capacitors around the socket. Performance wouldn't be fantastic, but it'd work.

You can't mount the WhiteWater blocks on Intel Socket 775 boards because of the capacitors in the way around the socket. On the AMD boards it's not an issue. You cannot modify the WW block to fit on S775 boards either - you will cause it to leak.

There's ignorance, which I can accept and have tolerance for, and then there's the deliberate display of ignorance, which for someone like me, can only interpret as intent to troll because there is no other logical explanation for it. FFS, I'm on the side of exposing and destroying harmful...

Guess you hadn't see the PD curves of the Stealth GPU block then? Swiftech's all about non-restrictive designs eh? Do tell! That block is close to 3x as restrictive as the Storm! Yes, it's a GPU block, I know. The point being that Swiftech haven't exactly followed the low-restriction...

I was talking about the Apogee GTX. I was talking about the Maze 4, but the Maze 3 as well - sure enough. Apogee GTX pressure drop That's with 3/8" fittings. At 1.5gpm, that's ~1.4mH2O. At 1.5gpm, the pressure drop of 3/8" barbed fittings is: 0.21mH2O At 1.5gpm, the pressure drop of 1/2"...

See, it is this point where you're on the wrong tangent. All blocks improve their performance with higher water flow rate. I'd be truly interested in knowing what led you to believe that blocks can perform worse with more flow. This has never been found to be the case in any review I've seen...

The system we're comparing is a DangerDen Maze 4, an Eheim 1048 or Eheim 1250, and a Thermochill HE120.2 with some decent fans on board. ~4 years ago, this was a high performance system in the USA. Interactive flow-performance results, on an 80W mildly overclocked CPU of the same era may be...

Ahh, my good mate, the mindless troll known as migueld. A quick perusal of the pressure-drop characteristics of the two popular blocks will find that they are still around 5-10x as restrictive as the popular blocks of 5 years back (Maze 3/4). Only the truly retarded troll would not check their...

Exactly. It makes it easier to justify it. :cool:

I also think that it's important to understand the clear distinction "small bore" and "low flow". Achieving 4.5lpm (~1.2gpm) flow-rates is not "low-flow", yet from the OP, we can do that with traditional small-bore tubing. 4.5lpm is mid-flow, heck, some low-flow enthusiasts might even claim...

I water-cool because it allows me the highest overclocks in relative quiet without needing to resorting to the more extreme cooling solutions, all of which are either impractical, expensive to run, noisy, or have a high maintenance overhead. It's not most bang for the buck. That would be...

She just seems utterly incapable of divorcing the issue of tubing size from the water-blocks from some particular manufacturer, attempting to turn analysis of the effects of tubing size into some pro-AC rant. Larger tubing will offer less restriction, and therefore more flow, on ALL blocks...

Seriously, whatever. I don't have the time to waste on you TN. Go focus your rants on someone who is prepared to entertain your dribble. I won't be.
