Plowing ahead with Bulldozer

As long as it's all working as it should then it's all good

the gtx 590 already is sli on the card itself so there is only a need for one ribbon cable

You'll need a long SLI bridge (ribbon or hard), as Arris noted (well spotted sir). More than a little surprising that Gigabyte did not include a flexible bridge given that the board allows you to nominate expamsion slots. No sense in buying a couple of Ferrari's then driving around with the handbrake on.(the high bandwidth requirement of the GTX 590 could/will make using the PCI-E bus interconnect as the sole communication between the two cards problematic to say the least).
EVGA here (3.5") - or pick up the 5" bridge that comes standard with the Asus triple-slot DCII GTX570/580
Sample EVGA forum thread here

Sorry if I created any confusion as the motherboard does come with the flexible connector. I just attempted some test fits with the more traditional (wide) bridge to no avail In fact, the one thing I really like about the GA-990FXA-UD7 is the spacing between the X16 slots. Makes cooling a whole lot easier.

The 4" PCB type didn't work Miz?
For some reason they included 4 SLI bridges (3 PCB & one ribbon) but only included two CF bridges. I had to call and have them send a third, odd as its a 4x SLI/CF board. But they did send it. (i have over 100 CF bridges accumulated), but these are the only black ones I have seen) So I decided to be bitchy and anal about getting the third

I originally installed the ribbon cable but when I couldn't get the SLI option in the nVidia control panel checked the others to see if they would fit somehow. After I followed up on your tip for the beta drivers the SLI option appeared and I was able to get quad SLI going with the ribbon cable.

Here are some preliminary results on the Corsair H100 performance. Snapshots were taken after 1 hour with the block set on low and at 30 minute intervals for medium and high settings. Ambient room temperature is 72F plus or minus 2 degrees as air conditioning cycles on or off. Fan noise is nearly silent on low, detectable on medium and clearly present on high but not really loud.

Overclock is CPU multiplier 20, Turbo Boost disabled, Core Voltage at 1.425 in BIOS, all power management features enabled. Memory timings are set manually but voltage is still at the 1.5 default.

Temperatures for CPU in Celsius:

Low - 40C ... Med - 37C ... High 36C

This weekend hope to find my highest stable overclock and will post back later with those results. Needless to say I am very pleased with these initial results

now those temps look good to say the least hope it keeps it up and hope ya get your 4.3GHz OC

...well...thats almost as cool as mine:wave:

Very close to having 4.2GHz stable under load and temperatures are only rising slightly

I'm still trying but I'm just an amateur at this compared to you.

I have my Silver Arrow fans set to low and am getting 40C temps...well readings anyway, as well (core Temp 0.99.8) @ 74F @ ambient @.4.2Ghz I was waiting for your results because I read a review that had the H100 and the SA in a dead heat...or dead cool depending on how you look at it.

for 4.2Ghz does 20.5 and 205 work? I run mine at 4.2Ghz 24/7, It will do 4.3 stable, but I am not fond of the voltage it talks, so its a benchmark speed.

i like these temps mizz will get there

i'm hoping he gets 4.4 out of his

Do you think it can drive quad sli? That is a nice overclocked so I hope so

can you tell me what programs yo are using to run your stress tests?

When you say "Block set on low" do you mean the pump?
I'm sure the Corsair info said to run the pump at its full speed at all times.
Found the pump at full speed just blends into the noise from the radiator fans and case fans. Don't find it to make much difference. I'm guessing it is possible that the H100 is a different beast though

Although it would sure be nice, I don't think so

Not to their full potential, started having some issues that I thought might be related to the beta drivers so for the time being have installed the HD 5870's. At least the 5870 is a known quantity and seems to be running quite nicely at 4.1GHz ... but not being maxed out by any means.

Initially, I use Nero to recode some video streams at high bit rates. This keeps the processor running between 75~85% and throws a good mix on the motherboard and disks. It also has the virtue of generally crashing to the desktop which makes it a bit cleaner and quicker to tweak things.

For extended stress testing I use AIDA64 Extreme Edition which works the processor with a good mix at a constant 100%. Also has the option to toggle whether or not to stress the disks, don't really like pounding the disk drives needlessly so I generally leave this off. Then throw in a quick run of 3dMark06 and if all is well try to click it up a notch.

Think you may be right about the pump speed, can only say for sure that the maximum fan speed is controlled by the switch on the block. Got the impression from the review on HardOCP that it might also control pump speed but may be reading too much into this statement:

In any case, it seems to be doing a pretty good job and noise is really isn’t much of an issue

Mmm haven't played anything recently that's really killed my dual 5850s but got the gfx card upgrade itch. Will see what the next gen offerings from AMD and Nvidia are like

This will be it for a while, especially since I pulled the trigger yesterday on the Intel 510 250GB
