It does provide support for the stock heatsink and the stock mounting pressure. When people water cool, they put A LOT MORE pressure on the PCB. And yes, the PCB will still warp if enough pressure is...

I prefer number 3 above. Generally, you will not see even a 1°C drop in water temperature from the inlet side to the outlet side of your radiator. So it usually doesn't matter if you split up the...

Exactly the point a few of us (I think) were trying to make. Having flow at around 0.5-1 GPM, you're talking about a 1°C rise in water temperature. Thank you for taking the time to pull numbers.

I believe the idea behind the X-bracket is to help keep the PCB from bowing. Having a ginormous heatsink wouldn't help prevent bowing, since the larger the sink is, the stronger (typically) it is....

Flow does not affect temperatures as much as you think. And besides, what's 5°C on water anyways? I'll tell you, a difference of about 5°C on your CPU or GPU... that's it. Living in a hot country...

Just curious... why do you want to separate the loops?

I'm running two rigs; one for gaming and one for a file server/HTPC/community gaming, and both run a single loop.

My gaming rig runs a...

It looks like the reference 7970's have the X bracket, but the GHz Editions don't. I didn't see any "reference" 7970 GHz Editions on Newegg, but I don't even know if they made a reference card. It...

I tried the 12.8's over the past couple days but nothing has been fixed :(

Steel, plain steel, is on the anodic end of the galvanic table along with zinc and aluminum, so it will cause galvanic corrosion if placed in a loop with copper. Stainless steel, on the other hand,...

Did you mean to say that you can mix steel and the other items you mentioned in an electrolytic bath without corrosion? I'm sorry, I'm confused.

Regular uncoated steel will corrode in water. I'm thinking you might have meant stainless steel... which for the people who don't know, does have some iron and carbon in it, but the main alloying...

They're just saying that the pressure of the fluid (water) running through the fitting should not exceed 71 PSI. If it does, failure will occur... most likely in the o-ring itself being unable to...

Well as it was, performance with 3 cards was equal to or SLIGHTLY greater than 2 cards. And going from 2.0 @ x16 to 2.0 @ x8 doesn't amount to any real difference. Benchmarks have shown that on...

Already got the 3930k and x79 platform and I was getting the same problems. And then the guy above suggested 12.4 cats, which worked on the x79 platform. So now I'm curious to try out the z68 board...

Tried a few more tonight. The 12.6b (05/31/2012) are the same as every other driver after 12.4... they just suck balls at loading all three cards. I finally settled on the 12.1a preview from January,...

Tried it out last night and it works like I would expect... and like you said. Thank you. What were your clock speeds on the CPU and GPU's? I was running 4.7GHz on the CPU and 1150/1650MHz on the...

I'll try that driver. I broke down and bought a Rampage IV Extreme and a 3930K to see if there was a difference and there is... but not much. Thanks for the help.

My main hardware is in the first sentence of the OP. ASUS Maximus IV Extreme-Z (Z68 chipset) with an Intel 2600K @ 4.9GHz; 2x4GB G.Skill Sniper DDR3 1600MHz RAM, and obviously the thread titled video...

No, the first slot is x16/x8 (if this and another slot are used, the 1st slot becomes x8), the other two are x16.

I just tried disabling ULPS through the registry. No difference when in crossfire or trifire, and again, I get the same 3dmark11 scores with 3 cards than I do with 2... 3 cards and 2 cards. I really...

Simply because they don't want to be held financially responsible for your screw-ups. Lots of things can go wrong, like electro-static discharge, tool slippage that results in severed circuits, over...

Average core temps/water in/varying pump power.

Averages are usually more telling than just a single core's maximum.

You definitely want to list the water temp as that is what's actually taking...

That's weird. I've tri-fired since the my 5870's (6970's too) and have never experienced a problem like this where one card has substantially lower usage than the other two. And I've never ran into...

No, but I tried running Sapphire Trixx and checked the "disable ULPS" box and that didn't help. Are there known problems with ULPS and Crossfire/Trifire?

So I bought 3 of the ASUS 7970 DirectCU II (925MHz) cards to put on my ASUS Maximus IV Extreme-Z with a 2600k @ 4.9GHz. After taking the card apart (and searching the internet), I realized that I...
