  Nitrous for your Computer? 
 Date Written 
Dave McLain Apr 29, 2005, 11:33am EDT Report Abuse
Last week I did some upgrading on a PC that I use for music work, recording, editing and processing in a multitrack environment. This gives the computer a real workout, I'm using 3 10,000 rpm SCSI drives on an Adaptec card to hold the data and 3 more IDE drives for system, backup and archive storage.

The new mother board is an MSI board with their Core Cell technology and a socket 939 Athlon 64 processor, 3000+ and 1GB of DDR 400 memory. This system really works great and it's very powerful and rock solid.

I've never done any overclocking but this new setup does it automatically based on the tasks at hand. When it senses a high load situation it gives the processor FSB a bit of a boost from 200mhz to around 220mhz or so maybe a bit more or a bit less for a short period all the while monitoring CPU temp etc. I've had no problems whatsoever with this system, I think it works great and it seems to me to be a good idea that instead of having the processor churning away at high speed all of the time only give it a kick when it's really needed.

Can someone with more experience in this area share any more info, I'm curious how this Core Cell deal has worked out over time for others.

Well really dynamic overclockings been around for a while...MSI on its own offered DOT for most of its big motherbaords and graphics cards....overall everything that has it on shows a good boost...although the boost isnt totally noticable it does give a boost for nitrous what about my liquid cooling system that sprayed supercooled gas into all my heatsink intakes whenever my comp goes to max load :P

And a kawasaki er-6n to mod instead

ASUS have a N.O.S. system on the newer MoBo's, my P5AD2 - deluxe has this. N.O.S. stands for >Non dely Overclocking System<. According to ASUS, its senses increases in CPU voltage and reacts accordingly - bringing in other relevant parameters to balance to help the system cope with a demand in load.
The only thing I don't like about it, and this is why I prefer the manuel O/C, is that it does not control the RAM timings nor frequency. What it will do is lower the frequency and loosen the timings - all for the sake of maintaining maximum system stability. But in the BIOS, you can enable it up to 30% boost with varying level of sensitivity.

This is my first experience with dynamic overclocking technology and at first I was a bit sceptical, it just sounds like something that could cause problems. Over the weekend this system was used for about 15 hours of hard use doing some overdubs and punch ins on a few tunes and it worked without any glitches whatsoever, very stable and fast. Once in a while I would bring up and watch the utility that allows the user to see all the action and during hard use it would clock the processor fsb almost 10% over, in this case 200mhz would run up to 217-220mhz and then at other times it would drop back to 200mhz, all this happening without any problems at all. Neat.

This dynamic overclocking technology could prove very interesting if used in reverse.

I've been looking for an ultralight notebook with serious numbercrunching ability for some time now so I can do monte carlo simulations when i need them, and I think i've finally found one in the Asus W5a. It is the only one i've found that can fit the Pentium M 770 chip and all its 2.13 ghz. The only problem is that installing that chip will suck the battery dry very quickly. I know asus has a software utility included that allows you to reduce the clockspeed of the processor when its not needed, but I was wondering if anyone knows if i can be made dynamic.

On another note, I was also wondering if one could dynamically overclock an Pentium M ULV processor like the 753 to give it any significant performance increase for mathematical operations.

Are you sure its the CORE CELL(D.O.T) technology and not the Cool N Quiet enabled in the bois?
I have the same MSI board and I dont have it enabled, At least I dont think I have. When I tryed to put in the core center utility it told me my board was not supported lol.

Must update the bios and nForce drivers.

In my bios there is a setting for dynamic overclocking, I have it enabled. There are several levels of dynamic over clocking, I have my computer set on the maximum setting which seems to work fine. This allows it to run from 200mhz front side up to about 217mhz front side clock speed. Hope this helps.

Okay, I know what it is now,D.O.T If you read the manual the overclock is done like ranks in the army ,sergent 1% captain 5% overclock etc. Instead of doing that why dont you just overclock it to the full instead of the fannying around business. Set it to the FSB you are getting from the D.O.T and set the Cool N Quiet on. Or leave it to the max without the C n Q. I would rather have the full power there all the time. Last thing you want is the CPU going up and down like a fiddlers elbow when playing games etc.

just check the temps with the core center.

In my situation some of my software decides it's no longer registered on this machine when it sees the different processor speed ALL the time. But it works fine when it's only using the higher speeds some of the time.
