Wah, I don't online for one day and buta already 5-6 pages from nothing..

is there possible to OC to 1 tera HZ?
using liquid nitrogen? just asking.
cause saw some guy using his pentium 4 OC to 3Ghz using liquid nitrogen
The world record is 1THz, but its using a prototype processor builts using Si-Ge, and it cannot run normal program code. It was cooled with liquid helium (FYI, its much cooler than LN2, and several times more expensive). Read about this in in-tech quite a long while back. Maybe the article can still be found in google.

its actually stable at 1.5v, but since my temps are still good even at 1.55v.. ive decided to leave it @ 1.55v for the peace of mind =)
Im sure u wont want to crash in the middle pwning in games xD
thx for updating bro.. but as for cooling.. ive ditched my cpns 9700NT and switched cooling approx 5 times till my current one already

You have to be very very carefull when you're dealing with temps below ambient. These sort of cooling method does indeed gives very good temps, but only for 1 overclocking session and not for long term use. If you're not carefull and didnt pay much attention to it and without proper insulation, the water from condensation will kill off your rig like roasted duck.
Not really, it also depends on the environment. If the air is perfectly dry, condensation will not happen.

Actually, Iced cooling is rather cheap. You dont have to go uber high end, you dont need a reservoir, and you dont need a radiator which can save up alot.
1. Pump = Get any pump from the aquarium shop which is submersible. Cost only approx RM20-RM45 (nirox P3800)
2. Waterblock, look for some used or any cheap second hand waterblock will do, might cost only approx RM50-150
3. Bucket = im sure you have one lying around ur hse...
4. Hose/tubes = just use any that you can find from your garden or get some gas tubes from your nearest hardware shop which will cost less than RM5
5. If ur lazy to make the ice, buy 1 pack from your nearest 7-11 which will cost less than RM5 for ALOT of ice.
Now... mount the waterblock on your cpu and connect the inlet/outlet tubes, on the tube connectors to the waterblock, wrap it with a cloth and ziptie/tie them. If possible, "spam" those Silica Gel packets that you see in a brand new shoe box or any stuff u buy that will prevent moist. It helps a little to reduce condensation.
Then.. connect the tube to the outlet of your pump, and just dump your pump in the bucket. connect another tube to the outlet of your waterblock and direct it to the bucket as well or if you dont mind keep refilling the water on the iced bucket and do not want the hot water to flowback to the ice, direct it to a separate bucket.
Power up your pump.. and you have an "Chilled Watercooling System"

Did this once, but had no camera to take pics..OCed my Pentium 4 Northwood to 3.7Ghz on almost stock voltage. Wanted to go higher but ice melted super fast-damn pentiums are so hot..

Most PCB these days can take up to 90c+, as claimed by crucial, their PCB is able to handle 85c. Brainpower pcb can do 100c+
Of course... an active cooling would help ALOT since these heatspreaders are originally designed to be cooled passively.
And another thing, please remember, do NOT use copper heatspreader unless you plan on using a high cfm fan on it. Copper does indeed absort the heat more efficiently that alu, but the heat stays in the copper as it doesnt dissipate as good as alu. Therefore, high cfm fans must be used if you plan on going copper heatspreader. Then again, the hottest part of the ram on stress is not the chip, but the PCB area near the gold pins.
The PCB can easily tahan 200C, but the ram chips..no way man..if they're too hot to hold on to continuously (at least 10 sec), then its too hot (~60C).
About heatspreaders..if you actually google up comparisions, most heatspreaders are actually not effective at all, in fact most of them actually
trap heat resulting in higher temperatures. The real advantage of heatspreaders is actually cosmetic, and also prevents physical damage to the chips. BGA chips are pretty easy to break.

you try to put ur finger on running cold water and cold water in a container....i dont know if it applies to WC in pc
but u said waterpump from aquarium shops....smaller pump will use smaller tube..and bigger pump will use bigger tube...my 6000/l pump for fish uses a hose bigger than those that you normally see ppl use at thier garden or when they wash car that type...and the one i'm using uses a tube which is like..half the size of my fish pump
You can mod the pump with barbs that match the tube you're using.

6000L/H
lol this is seriously overkill, im sure you are able to achieve better result with lower flow rate, try it =)
and i really do mean much lower, somewhere between 1200/1500L/H
this is exactly the risk of chilled cooling, applies to peltier as well. Good thing ur board is still workin.
Played with a peltier once too..but couldn't pump enough power to make it effective at full load. But even then, I had hell with condensation the moment I stopped prime, temps dropped faster than you can say oops..
6000L/H..damn you can wash car with that..

What is default chip voltage? Mine can go up to 1300-1400 without any issue. However, I don't seem experience better performance.
Who has try OC Phenom to 3Ghz? I heard TLB errectra issue only persists in Virtualization environment esp in Opteron servers.
The TLB errata applies to all Stars microarchtecture chips, not just in virtualisation (though its particularly problematic in that area). The errata is not caused by clockspeed, its due to circuit design and it will cause hangs at any clockspeed. Currently AMD has employed a microcode fix that works around the errata, but at a noticable performance penalty. My guess as to why AMD held back their highest end chips is because it makes no sense to release high end chips when you know you cannot get them to run at their fullest potential due to the errata workaround.

i don know hw to check pwm temp la~~
3rd party software can check?
Any DFI user can help?
Try everest. Never failed me in identifying sensors.

I think we cant check PWM temp. Not sure

But i always wondering what the system temp for which located in Smart Guardian. Is it PWM temp??
-pWs-Not likely. PWM temp is usually listed as AUX. System temp is almost always the ambient temp of the air near the motherboard.
