What is the maximum safe voltage for x48 north bridge on air, water and single stage(-30) and does memory overclocking scale with cold?

Water or SS 1.91v thats waht they go up to. With my Rampage Extreme with water on it @ 1.91v it would show 49c in the bios.
Scannick was using that voltage with an air cooler at the time.
Air probably 1.75 should be Ok

Watch temps so forth. 5 amp fan? Lemme see it!! My Delta is 1.6 amps and it screeeeeeems. Major air flow. The fan pushes the motherboard off the table if not careful!!  |

It scares me so much, if I run it at full speed it Flys like a drone. When I go home to visit my parents for the winter break I will grab it. I am currently using a few of the 1.6 amp ones from my mining rigs to cool the ras for my vm server loop and it stays at ambient even with my 1920x and 4 gtx 1060's. |

Haha that's awesome! I gotta get me one. When you grab it, take a picture for me.
I love big cooling like that. Almost all my WC builds where able to maintain at/near ambient air temp water delta.

x2 on the picture please... Vin I should be heading home Friday and will look through my box of fans for it. It doesn't even turn on when plugged into a motherboard header. |

So looking back I think it might have been a 24v 2.4 amp fan not 12v 5 amp. I remember not being able to to use the ant miner power supply for it so I am pretty sure it was 24 volts

Well 24V 2,4A is pretty much the same category than 12V 5A.  However 12V can be found in our close area more often I'm sure.  |

I'm pretty sure I only needed 1.55v for 550-600fsb on my RF DDR2 board and E8600 ES. I could only squeeze 600fsb because my G.Skill Pc8500 didn't appreciate more than 600mhz no matter the voltage. I might have gotten 610fsb. 550-575 24/7 was no trouble. That cpu was stolen from me so I cant help beyond some faint memories. I have a Xeon x3360 for that board now, and cant really squeeze more than 475fsb reliably out of it unless I spend some time with it. Not sure if its the board or cpu. Probably both.

Does anyone know how stable spi 32m fsb scales with cold fsb? Is it about 1mhz per 10c decrease or is it even less?

I found GTL tuning to be one of the more useful things for pushing the fsb. For the longest of times, my P5E seemed like it wouldn't go any higher than 500, even when freezing the cpu with dry ice. After a lot of tweaking, I managed to hit something like 575 with the same board, but it took hours of trying various different combinations. And of course, I didn't write down what I did to get there. Oops.
Voltage is of course helpful, but always start with as little as possible, and slowly move upwards with it. The fun part with LGA 775 is the different voltages to run (fsb termination, fsb, core, ram, and I'm probably missing a few others too) and how, in some ways, they work together, while some CPUs will be weird and love 1.8Vcore, but throw a fit if VTT? (fsb term voltage) is above 1.5V...
