Room is about 23-24°C. Radiator is cool to the touch. Pump is a Alphacool DDC.


Idle is now after some playing with the tension on the nuts.
Core0: 39°C
Core1: 36°C
Core2: 34°C
Core3: 38°C

Now whats the load on those.

Do it under load. I forgot to mention that

[fat jez]

Now whats the load on those.

Full load is now:
Core0: 52°C
Core1: 51°C
Core2: 49°C
Core3: 50°C

So getting better.

There seems to be a lot of gurgling going on, which makes me wonder if I still have air trapped somewhere. I do have a small bubble in my res which I can't get rid off, due to the fill point position. Bleeding the radiator only produces liquid though, no air.

I'm also half tempted to ignore the official line on applying Arctic Silver and just do the old style thin spread across the entire chip. Then follow Clunk's approach to tightening my nuts (oo-er )

You can still do it by covering the entire chip, but you dont need to.

If you turn everything off, and then find where the air bubble is, and then lift the case up and tilt/guide it to the res or the rad and let it out.

OK guys, I now have under full load, after reseating several times and going from Arctic Ceramique to Arctic Silver 5:

Core0: 49°C
Core1: 48°C
Core2: 45°C
Core3: 46°C

Much better than I started with!

Was it a big air bubble in your pipe, or were your nuts loose?

[daza]

Right I'm going for it today.

Got fed up of the 360fsb (want my 3.4ghz back) I had so I'm going with 380x9 with 1.41v under load as the board wont take a 400fsb, north bridge is at 1.6v

All cores are at 62c and the PWM's are roasting marsh mellows at 90c all on prime 95, hopefully the board will last till I get the x38 version in September.

Not sure. I seemed to manage to get some more water into my res, so there may have been some air somewhere. But I also reseated the block again using Arctic Silver 5 instead of the Ceramique and then played with my nuts a little (oo-er again).

Should I be aiming for better though, or is that reasonable now?

...System is a B3 Q6600 on an ASUS P5K-E WIfi with Corsair DDR2-800 RAM CAS5 (2x1GB, black slots)

I've stuck my ram in the first 2 ajoining slots (the two on the left), does this make a difference to performance - should they both be in black slots?

Stick 'em both in the same colour slots, you'll get the benefit of dual channel performance then.

Great stuff ill do that then Is it much of a performance boost?

Looks ok to me. Did you try tilting the case with everything turned off?

Yes, both in the black slots.

Which is best, 2gb in dual channel or 3gb which i assume wont be dual channel (correct me if im wrong!). All would be ballistix 800mhz stuff

The case has been wiggled, jolted, tilted, turned on it's side, everything I could think off With the power off of course... The other thing I have done is run it tipped back at about a 20 degree angle so that any bubbles while running should get trapped at the front of the res and not sucked back into the tubing.

I can still see a lot of small bubbles in there (as in the size you get in a fizzy drink), but otherwise I think I am have most of the air out. I still can here it fizz in places, but I wonder if that is just turbulence as it passes through the waterblock?

Depends how you do it. If you have matched DIMMs, it will still be dual channel, e.g. 2x1GB, 2x512MB. If it is 3x1GB, then no, it won't run dual channel.

Ok, well, one of my loops was like that, and it was because the turbulence from the flow was causing a vortex insite the reservoir and dragging air back into the water. The only way of fixing that on mine, was to have the reservoir filled right up to the top.

Once all the air is out, it will become pretty much silent.

That's kind of what I thought. I am thinking about shifting everything to a bigger case and ditching the res altogether and using a t-line with a filler tube instead.
