Evercool PPGA/FC-PGA slocket

Intel created quite a stir when they released the FC-PGA Coppermine CPUs. Only problem was that few consumers were willing to give up their BX boards and switch to the Intel i810 or i820 boards just to update to the latest Pentium design. Then Iwill hit the scene with their Slocket II, which allowed a FC-PGA CPU to be installed on a slot-1 BX board. Not only did the Iwill unit correct the voltage problems many BX boards would have, but it more importantly corrected the pin-outs of two critical pins on the FC-PGA to allow it to interface with the BX chipset. Shortly thereafter the market saw many new FC-PGA adapters hit the market from different manufacturers.

Evercool sent us their new FC-PGA adapter recently. What struck me about this unit was its total lack of jumpers. The Iwill unit I had reviewed earlier had no less than nine jumpers on it. The jumpers on the Iwill slocket were used to designate the CPU voltage, PPGA or FC-PGA CPU, FSB, and whether the CPU was an Intel or Cyrix chip. So I scratched my head and kept staring at the Evercool unit. It looked just like an ordinary PPGA slocket, but silk-screened on it is PPGA / FC-PGA. Its beginning to look like Evercool has one of the easiest to use slockets to date.

The adapter
  • Supports all Intel PPGA and FC-PGA CPUs
  • Works with BX Slot 1 boards
  • Auto detects host frequency

I want to tell you right up front that the installation of this slocket went without a hitch. I had some trouble with the original Iwill FC-PGA slocket because of the handle on its CPU socket. Once the Coppermine was placed in the Iwill unit I had a problem with the aftermarket GlobalWin heatsink not sitting flush on the CPU. As a matter of fact, there was quite a noticeable gap when the heatsink was held up to the light. After a little tinkering my solution was to bend the arm of the CPU socket with pliers to get a good fit with the heatsink. I let out a sigh of relief when I mounted the same heatsink onto the Evercool slocket. The fit is very tight Ė but the heatsink does clear the socketís arm. This unitís PCB is just slightly shorter than the Iwill unit Ė about the width of a nickel. That isnít much, but it does help in extremely tight situations like I encountered with the Palo Alto ATCX case. Likewise, the PPGA Celeron mounted without problems. Anyone who doesnít like the idea of taking hand tools to their new electronic toy will like this unit.

Its time to play:

One area where I was concerned was with FSB support. Iwillís jumpers allowed the selection of 66, 100, or 133 FSB with an additional feature that allowed the motherboard to select the FSB. This unit has nothing like those jumpers, and even stranger, in the upper right corner of the PCB is a soldered on selection of Auto or Overclock. Mine was soldered to the Auto selection. I was beginning to wonder if I had to resolder that connection to the Overclock position to allow me to use some of my motherboardís available FSBs. Good work Evercool, the slocket not only worked at normal PPGA and FC-PGA FSB speeds, but handled odd speeds like 138 and 144 MHz without a problem. As a matter of fact, my 500e FC-PGA previously only reached 690 MHz (138 MHz FSB) with the Iwill Slocket II. The Evercool slocket ran 690 MHz without any problems and I hit 720 (144 MHz FSB) MHz at which point it locked up at the Windows splash screen. The Iwill unit never even posted at this setting. I donít have to tell you just how out of spec that is compared to the normal 100 MHz this CPU is designed to run at. I fired off an e-mail and was assured by Evercool that the "Auto" setting will allow the motherboard to determine the FSB.

The only thing I can see on this slocket that may be a problem is its lack of voltage selection. While most BX boards are now supporting 1.6 v (and lower) with their latest BIOS flash, if your board doesnít you may be in trouble. Both of my BX boards support the new lower FC-PGA voltages natively, and I would venture to guess that most of the BX motherboards on the market do, also. Make sure you are sure though, since waiting for another adapter to come in while your FC-PGA processor sits in its box could really test your patience.



  • Totally jumperless Ė and it works
  • My big heatsink fit without problems
  • Overclocked better than the Iwill unit


  • May be hard to locate under the Evercool name (see below)
  • No Cyrix Joshua support
Iím not an electrical engineer. If I had to come up with a reason why I had better overclocking experiences with this slocket over the Iwill unit I would guess it had to do with Iwillís jumpers. To make the jumpers easy to access they are located together on the PCB. This means that some of the tracings have to travel to the jumpers before they can return to their destination. That can cause signal degradation. With no jumpers, the tracings on the Evercool slocket are kept to their shortest necessary length. This helps to maintain signal strength and quality. I suspect some "noise" may be introduced with Iwillís jumpers.

Evercoolís slocket is by far easier to use. Iím glad to see that a jumperless design works so well. Cyrix Joshua chips will be giving the Coppermine a run for their money soon, and since their architecture is specifically designed to be compatible with Intelís, you would think that it would be an easy swap, right? Wrong. This slocket wonít support the Joshua chip. At this point I canít tell how much of a hindrance this will be for this slocket. If you have any plans to upgrade to a Joshua processor then look elsewhere. If you decide youíd rather just stick with Intelís PPGA and FC-PGA then by all means pick one of these up. Keep in mind that your motherboard needs to support the lower voltages that FC-PGA processors require so that you too can be running with this jumperless FC-PGA slocket.

When I contacted Evercool for a distributor of their products in the U.S. they recommended CWC Group. I went to CWC-s site and didnít see this slocket listed. I wrote to CWC, but after a week of not hearing from them I canít give you the pricing or availability of this unit. A few vendors are selling jumperless FC-PGA adapters so you may want to find out if it is the same unit I tested here. I couldnít find Evercoolís name on the packaging, so vendors may be listing it as a generic unit. Hopefully theyíll let you know who supplies their generic unit. Now thereís something I like to see, the new guy beating the established favorite, and probably for less money too.
