Putting it all together.
So here we are, everything in, fittings on, ready to start the tubing planning. Note the two fans up top which are exhausts? They are mounted as far away from the motherboard as physically possible, but I couldn't put one in the middle because it would get in the way of the tubing coming out of the top cpu block.
Close up of the top of the mobo area:
The 240 rad in the bottom (fans set to exhaust)
Final tubing plan:
Res -> pump -> CPU0 -> CPU3 -> CPU2 -> CPU1 -> 360 Rad -> 240 Rad -> Res
This gives a best compromise, as otherwise the top CPU only gets reached by the time the water has gone through three constrictive blocks plus gravity working against it to get there. This way its only the second block in the loop and then gravity is helping to get to the other blocks, the rads and back.
Some close ups:
Risky pump location, but hey, I'm livin on the edge!

Surely not the last update??????
How does it overclock?
Any photos of it up and running or have I misunderstood your last post....?
Heh so I lied, sorry wasn't the last update.
So leak testing shots and some videos!
First leak testing with pure distilled, also helps blow out any bits of crud left anywhere and helps identify any difficult air traps that I'm going to have to work on later.
Some videos, first a video of the airlocks being chased around the tubing, took ages to get them all out
Eventually was left with a few bigger bubbles working their way out as I tipped the case around.
So after the successful leak test (which did show up a slight leak around the pump, fixed with a few turns of the screws) then its in with the fluid I'm going to use.
This is Nanoxia Hyperzero ReadyFluid - Clear Protect, its clear which I like, and its anti corrosion and anti algae properties should be put to the test nicely in this situation
Its white from all the bubbles, and it made a load of froth, but eventually it all settled down.
I'll put some finished shots up soon, but currently its overclocked 25%, so pretty much 2.3Ghz out of 1.8Ghz chips and stable just bumping the volts from 0.9 to 1.0375V

Excellent work there. I'm keeping my eye out for a H8QGi+-F board - I'd like to know how easy the process of flashing the oc bios was and then the actual process of overclocking.
Any screens or videos of that?
That's one hell of a machine you've managed to build there....

Excellent work dude.
Problem is memory, at up to 250 base clock it runs at 1066 speed + the OC so 1066 x 250 / 200 = 1332.5Mhz and I don't think the DIMMs I use like going anywhere above 1333Mhz
Faster DIMMS and some good chips and you shuould be ok up to 260-265I'm happy that I bought £240 CPUs and am running them at £700+ CPU speeds at lower volts is good enough for me.
Its all tear at [H]ardforum's fault hes the one who created the OC'ed bios and all the instructions you need are in that thread
Supermicro H8QGi/6 and H8QGL Next Generation OC BIOS
It varies, usually a closed loop equalizes in temperature after a while, but these blocks are quite restrictive. Currently its 45-47°C so a variance of 1-2 degrees across the cores is pretty even. But I've seen much greater variance where I just went CPU0-CPU3 in that order, the temp difference was nearly 10°C esp when the blocks gunked up.
Thanks for explaining.
I can understand heat transference dropping as the fins gunk up. Just assumed as each each CPU/block dumped heat into coolant that by the 4th CPU it would be warm enough that block would not be as efficient as first was and that CPU would be a few degrees warmer... Obviously it's not enough to make any difference.
So radiator intake temp vs output temp is not a big difference either? aka "equalizes in temperature"

Just to understand, are you saying that the limiting factor in your particular build is the memory. Is there any memory that you are aware of that runs on that mobo that would allow you to record a higher overclock, or is that about it for that particular cpu/board setup?
