The Slocket II is well designed for it’s purpose. One very nice feature is the SECC-like framework around the Slocket II PCB. This allows the device to be inserted and locked into place just like an SECC processor. There is a single row of jumpers for selecting the FSB speed, the CPU package type (PPGA or FCPGA), the voltage and even the processor manufacturer (Intel or Cyrix). These are all 3-pin jumpers and when all are jumpered across pins 1 and 2, the card will simply pass through the default signals to the Slot 1 connector.
Stability – Our first set of tests were intended simply to make sure that with the Slocket II running at default settings with an FC-PGA and a PPGA processor, there would be no stability problems. We ran the Passmark Burn-in program as the primary test, because it has several CPU specific tests (integer and FPU), though we did not limit the test to these functions. This test ran for over 24 hours using both a Celeron 333 (PPGA) and Pentium III 500E (FCPGA) without any errors.
We next installed our PHD PCI card from Ultra-X and selected the processor tests from the menu. Our final stability test was with QuickTech Pro 2000, also from Ultra-X, which has several CPU specific tests that are essentially the same as the PHD PCI tests – however these are performed at a higher level. The PHD PCI tests are run directly from the PHD card, before any operating system is loaded, while the QuickTech Pro tests run under DOS. In both cases, the tests ran without showing any errors.
Function Verification – Once we verified that the card worked without any problems at default, we next decided to try to change the FSB settings to see if the CPU signals would be properly overridden by the card. We were unable to test the Intel/Cyrix jumper due to the lack of a suitable VIA/Cyrix processor. We had no need to use the voltage jumpers, and so left them at default.
Using the PIII 500E, we set the jumpers to 66MHz, 100MHz and 133MHz FSB speeds. In all cases the KA-11 motherboard was ‘fooled’ into thinking that the processor ran at these FSB speeds. This allowed us to boot the 500E as high as 750MHz (though memory limitations prevented any stable operation at this speed). We next installed the Celeron 333 and set the jumpers for various FSB speeds. In this case, the motherboard successfully ran the Celeron at both 333MHz and 500MHz, but would not boot with the 133MHz FSB (CPU limitation).
