is that aluminum and brass?
6 GHz is plain MAD!
if only power is a limit maybe we should make new one ;). I'm sure that on this forum is enaugh specialists to make brand new mobo supplying :>Quote:

what an awesome result ! O_O makes me speechless ! congratz to the clockers !
Sweet looking containers there Otternase :)
New copper soil for the next test!!!
Amazing stuff u guys are doing there.. love how all the caps around the cpu froze..
u guys sure its sucking up close to 300watts at load. that seems a bit INSANE. boy that would put a load on any cooling system. ln2 or not.
At the rate intel is going if you oc one mhz u have to go to water or above.
very cute stuff guys ! :toast:
the next test can come :YIPPIE:
WAY TO GO!!! woot!
To give you an update:
We made on sunday a pre-test with a Fatal1ty, but not a final shot:
Keep up the good work

And again, the caps have to be charged, they arent like a battery. THey become a load on the power supply after they discharge to the voltage of the supply.
If your power supply aint cutting it, Industrial power critical system SMPS's could be made to work with a computer pretty easily. The amount of current would only be limited by your bank account. I wouldnt trust anyone on these forums to do it based on what I read here everyday though. non-isolated High current electricity and computer nerds do not mix.
The motherboard could be modded to lower the parasitic resistances that are making the voltages fluctuate madly at these high currents. The toroidal output inductors for the SMPS's are not very large and high in resistance considering the current flowing through them. Winding larger (Size not value)custom made inductors would be very beneficial, but you'd have to get someone who knows what they are doing or else you'll be hurting ripple performance too much and risk a destroying a cpu. Winding several small strands of copper is much more effective than one large diameter solid core wire. I would go slightly less inductance to increase transient response of the supply and reduce the series impedance of the inductance.
Not sure, but the motherboard regulation circuitry probably has a built in current sense/limit on the Vcore line which would need to be removed/modified. At high currents, circuit board traces become a series resistor in line with the load. Something would need to be done about the path current takes in order to reduce resistance as much as possible. When dealing with small voltages and huge currents, 1 milliohm translates in to a very large voltage drop percentage wise. This is the reason for voltage sags on the Vcore line on any well designed motherboard.
More/Better filtering will be needed to compensate for larger ripple due to higher current draw and modified inductors.
This is the basic outline of what is needed to supply more current to the CPU. I'm not sure if anyone on these forums has the electronics knowledge to do these types of mods in a way worth doing... I hope I'm wrong. I'd like to see it happen.

As written, just a pre-test without optimized timings... :D
We still waiting for additional components...;)
Now this is someone who absolutely knows what their talking about. Thank you this type of knowledge is not only beneficial, but is most refreshing when theory is based on fact rather then conjecture. best response I've read to a post in some time.Quote:

That pi is too slow. unpatched I can match that at 5.6Ghz maybe 5.5ish on the DFI or Asus. the dothan at 3.07Ghz pulls 25s
memory on 3:2?
SPL15: I fainted after i read that....
I forgot about Hippro... He should definately be able to pull those mods off.
I'm sure I could, but I've got enough contracts at the moment to keep me busy for the next 2 years. And plus my hourly rate is quite high because the companies I work with have very deep pockets.
Lets hope Hippro has some spare time on his hands.
@Fugger: Thanx ;)
Yes, unpatched, to be honest, we didn´t konw up to the weekend, that a patch exists... :rolleyes:
CPU:RAM = 1:1 (instable RAM at higher FSB, I think the Bios ist still not really developed)
I made a test yesterday at this system with FSB 220 / 3:4 ->
unpatched: 32 s
patched: 29 s :D
So, next time we hope to perform better!
good luck and uncanny setup
keep it going....
This Weekend :rolleyes:
