In the case of a 500 MHz G3 Crescendo card, we have qualified two processors. Processors have an inverse linear relationship between operating temperature and speed with a factor of 0.85 MHz per degree Celsius. To ensure reliable supply, we qualify any appropriate available parts from the manufacturers that will operate in this environment. Sonnet is conservative in all of its chip selections, and specifies processor operation to 65 degrees C. A G3 processor (with heat sink and airflow in these desktop systems) runs about 10 degrees C higher than ambient, so the resulting processor chip must run reliably at 35 + 10 = 45 degrees C. For these reasons, Sonnet's warranty is void if the heat sink has been removed.Īpple specifies its current desktop models to operate at ambient temperatures up to 35 degrees Centigrade (95 degrees Fahrenheit).

If this is not done correctly, it can result in a warped card, or even a cracked processor die. In addition, Sonnet heat sinks are screwed down with a specific sequence and controlled torque. Breaking the thermal seal can result in erratic and unreliable performance if the seal is not perfectly re-established. Note: Despite the inclination to do so, you should never remove the heat sink from a Sonnet upgrade card. The relationships between these parameters are well known by the chip manufacturers, and are communicated to OEM customers like Sonnet. Every chip has an operating space based on three parameters: speed, heat and voltage. Different applications have different cooling systems (heat sinks, fans, etc.), different airflow and different operating temperatures. We select processors based on the intended operating environment. We are always conservative with our customers' machines, and with how we select processors for our many upgrade products. Sonnet sells and guarantees reliable products, as we have for over 20 years.

The speed indicated on the G3 or G4 chip on my Sonnet processor upgrade doesn't seem to match the speed of the upgrade I purchased. May I discard my original CPU after installing Sonnet's upgrade cards?

As long as the Encore/ZIF is properly installed, there is a solid benefit in virtually all applications.

Benchmarks show that the overall result is a very positive gain for Blue & White owners. In the interest of offering the fastest-ever G4 upgrade for these users, the decision was made to adjust the bus to allow for flawless processor operation. Why does the Encore/ZIF (700MHz and faster) require that my Blue & White or PCI Graphics G4 bus speed be slowed to 66MHz? Doesn't that slow down my computer?ĭeveloping a high-speed G4 upgrade for these systems required some very advanced engineering, and one of the compatibility issues could not be resolved with the bus at 100MHz. The Crescendo/Encore installer hangs, or crashes the system occurs most often when run from the Sonnet installer CD.
