  K7 JumpStart  
         
  Here it finally is, the ultimate AMD K7 "Athlon" OC-adapter mountable on the so called 40 poled "Goldfinger" connector on top of the Processor.

It is even offered in various versions, such as angled or upright with front or rear access respectively, and with optional L2 Cache Multiplier setting! No, you didn't misread "Level 2 Cache Multiplier" setting.
Additionally it' might even be the smallest in the world and only one that fits inside the VapoChill CPU kit, and as far as we know also the only one that has taken some measurements towards EMI issues, finally the power consumption has been reduced by the use of real Dual pole changeover contacts disconnecting the Pull-up resistor, for each of the signal inputs to the processor whenever a "Low" or "0" is selected, and visa versa.

All these attributes insure maximal flexibility, stability and assist you in maximising the performance of your CPU.

 
  As you can see on the picture here to the right it is not much larger than the space the DIP-switches themselves require, and thereby it might just be one of the smallest OC-Cards for AMD's ATHLON K7 in the world,nevertheless it has more functionality and better properties than any of the others we know of at present (19th of Jan. 2000).

It is offered in either angled or upright (as shown here) basic versions, providing either top, front or rear adjustment access, in order to comply with your specific needs, depending on PC-Case (possible PSU just above CPU) or whether you have forced-Air, liquid, or compressor-based Cooling system on your Athlon processor.

  
The presented upright version is suitable for use
on a CoolWhip Liquid system.		  
  Moreover an option to control the L2-Cache Multiplier is offered (as far as we know the only other unit that offered this, was an early fully soldered wire version offered by Trinity). Our solution only requires you to solder 4 small pre-cut and pre-soldered wires on to the processor board, it is fairly simple, and a fully reversible process (if you ever want to take it off again). The Wires are connected to the JumpStarter with a tiny plug that fits in a small counterpart there, thus you can always exchange CPU's using the same OC-Card without doing any more de/soldering work.
For test purposes we can offer extra wiresets (in the future called "JS-L2-wireset"), so you can leave them on the CPU, and just mount the new JS-L2-wireset on the next CPU.
  
Here you see the 4 wires on the L2C version hooked up to the L2-cache resistors (note: various setups proposed!).		  
  Well, why is it not controlled with Dial knobs?

because Dial knobs does not offer the attributes that we wanted. Normal DIP switches only offer an ON/Off function in one contact knob. By using a Dual Pole Tripple In-Line type DIP switch we manage to reduce power consumption and still get a perfect signalling to the CPU, as the "pull-up" resistor is disconnected, before the "pull down" is connected and visa versa. This in particular reduces the load on the already sufficiently overloaded V-Core supply. But all the signals are treated in a similar manner, just as a matter of good practice.

  Of course the Power Supply connection is delivered with a HD Power Supply extender cable, so you do not have to run around finding a HD PSU split cable to hook it up. Moreover the circuit is EMI decoupled with a toroid coil, in order to reduce EMI emission coming from the CPU.

This will assist in reducing the probability of Operational disturbances at the higher speeds, and reduce interference issues not only to the other internal PC-equipment, like sound and videocards, but also surrounding equipment like radio and TV-sets (in worst case those of the neighbour!), which otherwise could arise.

There are currently 3 different basic models to chose from for various applications. Those are either upright straight with the processor PCB (note the OC-board is not offset to the processor PCB, due to the special connector used) adjustments operated from the front (for CoolWhip Liquid Cooling system) or adjustments operated from behind (for VapoChil compressor based Cooling system inside the CPU-Kit) finally the "angled" version adjusted from the top mainly for use with large forced Air Coolers like the CoolWhip Air or the newer CoolWhip Air Stack coming shortly now). We will of course show all of them, as soon as we have taken pictures of the individual set-ups in connection with the various coolers

  
  In order to offer a reasonable low-cost version all models are offered without the L2-Cache option, which at time of ordering can be selected, at an additional price including the cable and plug required for mounting on the Athlon, for those that prefer the full flexibility. Depending on the various CPU's there are both 1/2, 2/5 and 1/3 selections available. Four bits are adjustable, so other L2-cache settings might are also be available, on some CPU versions it seems that R105 of the CPU has effect on 2/5 selection, we are not sure of this, but the choise is yours depending on whether you solder on to L2-ID bit 3 (redundant at present) or "R105".

Well, that's all very good, but how much? If you have a tiny bit of patience left, you can check it out right here

  
   
  External Dual-temperature instrument.  
     
  A super universal temperature measuring-instrument (with Clock and Celsius to Fahrenheit conversion too), where you can connect 2 probes so you can switch between reading say the backside of your CPU, the cold side of the Coolplate, the hot side of the heatsink, the temperature on the 3D graphic Controller, the temperature inside the PC Case, or on the HD etc. etc.    
     
  It maintains a very decent accuracy of +/- 1 degree in the area between 0 and 50 degree Celsius, so that's quite OK, as this is the most common area for that sort of measurements anyway, and furthermore it handles temperatures as low as -20 degree Celsius, though the accuracy at these low temperatures goes down the drain, so you have to keep that in mind and compensate accordingly, if (or should we say when) you need to measure subzero temperatures. As a rule of thumb it offsets relatively approx. +1 degree for each -5 degrees below 0.  
   
  We offer it with one probe included, then you can buy as many extra probes as you want, and then just connect to them in turn or alternatively hook the probes to a rotating switch, just like that! This is considerably better than moving one probe around, as it often gets destroyed in the process of pealing it off.

The instrument is driven from a single 1.5V penlight battery, which is of course also included, so just connect and get going.

For the first time it will be possible to exchange temperature measurements with adequate consistency, as long as you inform you have used this instrument. This way perhaps we can avoid the sometimes very strange readings that pop up from various sources in mails, and concentrate better on where to isolate a given OC'ing problem.

  

this is how the probe looks like,
had we put a match in the bag,
it would have just fit across .

  CPU Safe Operation Conditioner  
     
  This amazing little piece of H/W can assist you in obtaining higher overclockability and stable operating conditions for your system, thus eliminating troublesome HD crashes etc.

It monitors the CPU temperature even from before the PC starts to work, and can postpone start-up of your system until the temperature of your CPU has reached within safe operating conditions for your desired CPU Speed.

Initially developed for AseTek in co-orporation between AseTek and ACDC.

  It indicates by a RED/GREEN LED when safe operating conditions have been obtained by your cooling system, and can prevent the system from starting until an additional temperature safe margin has been reached.
It constantly monitors the temperature, and will turn RED if temperature rise to critical level, and finally stop your system, before the CPU starts doing crazy things. A selection of jumpers allow you to define the temperature operating points of the conditioner to suit your particular set-up.

It hooks simply into your system by the standard HD power connector (without actually occupying any of the sparse outlets, as it provides a passthrough), and with the self adhesive backside, it can sit anywhere inside your PC.

The 5mm indicator LED can be placed in the front becel of your PC Case, or where ever you prefer it. Temperature probe is of course also included to adhese to your Cooler or CPU.

Standard operating range is from +15 degree Celsius down to -25 degree Celsius. Given sufficient demand, we can adopt a version for a different operating range, and there are 7 set points available within this range.

Several Conditioners can be inserted in series (cascaded) to monitor several critical temperatures, and not until all temperatures are within safe limits, will the system actually start, likewise if just one gets out of range, the system will halt immediately.

Many monitoring programs can actually take over the stopping and warning of system unsafe conditions in an allready running system, but NONE of them can handle the start-up problematics involved when the CPU cannot operate at all until a sufficient low temperature has been reached !!!

  
   
  Peltier passive regulator block  
     
  This passive regulator block allows you to fine-tune your Peltier cooling performance in that it provides better balance between your Heatsink characteristics (C/W value) Peltier pumping effect (Delta T) and the Power consumption of your particular CPU.

It is easily mounted on the inside wall of your PC Case and installed on the powercord for the Peltier elements (but make sure it does not also regulate the power for the Fans!)

  
It is shown here without the heatsink on which it is
mounted, in order that it itself does not get too hot.		  
     
  Due to the different power consumption's of different processors, a Peltier dimensioned to drive a maxed out Celeron 0.25 micron at >600Mhz full load, will provide much better Cooling if balanced properly between the abilities of your Heatsink and the actual Power consumed by your particular CPU.

There are now differences between PII, PIII and Celerons and between 0.25 and 0.18 micron technologies (the latter drawing much less power) This fact can be exploited to give you much more benefit of your Peltier Booster.

Delta T will drop, but as long as the Heatsink temp. drops more, you will gain lower CPU temperature. It has proven to reduce temperatures by up to 10-15 degree Celsius on the heatsink, and 8-10 degrees on the CPU.

Note: This product is only useful on over dimensioned Peltiers like +80W on Celeron/PIII.
