Xtreme cooling inbound.
Hooking up the tripple cascade

Impressive stuff... do you have the DDR800 option available on your Asus board? Mine stops at DDR2-667.... can you verify?
-
once you go over 220 fsb it will show the 800Mhz option.
-
Please give us some results with the cascade :).
-
How is the FSB scaling on these?

Do the northbridge and southbridge not get hot with the overclocking considering they are only passive cooled?
-
They get hot. I also noticed a strange trend when adding a nb fan. I experianced what Berkut is talking about with thermals through the roof on the CPU. I removed the nb fan and everything seems to have gone back to normal.
-
That seems the only problem with the new Asus intel motherboards. For some crazy reason they have all passive heatsink on them. Even the NF4 version is the same.
How is the vdroop on these newer boards have you encountered any yet?

That's odd. I'm currently building my P5WD2 Premium up right now and replaced the aluminum nb heatsink w/ a thermalright nb-1c. I put the fan on and I'll see how it goes when I get it started up.

I went over 220 FSB, and the option did not appear. The only way for me to hit DDR800 is if I adjust the CPU to 266 Mhz, which means that it is still running the 3:4 divider. Can you let me know what bios you are running?
And are you selecting the 1:2 divider through the bios or through A.I. overclocker? Because I swear, we have two boards, but both of them don't show the DDR2800 option whatsoever... it only goes up to DD2 667.

Man with all the issues im hearing....thank god I didnt get one.

Looking at Fugger's board. The bridge heatsinks on mine are different.
-
Mine looks exactly like Fugger's, and yet the DDR2-800 option does not appear.
-
Fugger ,whats the highest fsb you can go with this chip?
-
For the DDR800 option depends on the bios and what memory you are running. I have had two of these boards and the first had the option the second did not. It was an easy fix, just swapped out the bios chips. The sad part is the second didnt overclock as well as the first.
Fugger, you say you are running stock voltage, correct? I hope that is just a CPU-Z misread then. 2.7v is a little high on air cooling :)
I am watercooling the cpu and NB. I havent noticed anything strange with the thermals. And have been using the system to run D2OL x4 and the cpu OC'd to 3.7ghz @1.4v and the temps sit about 55c.
The vdroop on my system is about 0.1v from 0% to 100%. I have the vcore set to 1.4v in bios and drops to 1.30-1.33v at 100% load. But the system is stable running Prime95 x4 for 24 hours.

hes got an older one im pretty sure cause i have the same heatsinks as him. i think its from when the board came with the tv-wifi card.

lol a little high???? it turns out cpuz displays the sum of the voltage of both cores. so, its prolly 1.35 (Stock) :fact:

The voltage reads right on my P5WD2 and 840es in cpuz. I've never heard anyone else say cpuz adds the cores together. What do you mean by "it turns out", I've never heard of that before?
-
Older versions of cpuid (screen shot about 1.28.6) was reading incorrectly and adding the two cores together.
-
What soorta hd you running? I dun see any sata connections...
-
very interesting about 1.28.6 CPU-Z. The only versions I used on those boards were the 1.29 and 1.30. So I didnt see that misread. Thanks for the info Fugger.
Wiggy, Both boards that I have had my hands on have that same heatsink on them. And they dont have the T WiFi cards either.
