3009.0. "Evergreen Technologies CPU upgrades" by SANITY::LEMONS (And we thank you for your support.) Mon May 12 1997 15:14

    Hi
    
    Does anyone have experience or knowledge of the Evergreen Technologies
    486 and Pentium upgrade products?  According to information on their
    Web site (http://www.evertech.com):
    
    	"Based on AMD's 133 MHz 5x86 PFQP processor, this is a
    	 one-size-fits-all upgrade for 486SX, DX, SX2, DX2
    	 desktop computers and boosts system performance to
                                           Pentium levels."
    
    Thanks

	Works fine, though had I to do it over, I'd put the money toward a new Pentium (or better) motherboard. Mine runs too hot and the system will hang without a lot of air flow over the cpu. A friend has the same upgrade, and his runs cool without additional cooling... Go figure. Bill

	We installed a bunch of them in the office and for the most part they seem to be fine. Stuffing a 586/133 into a 486DX/33 will give you a 133 MHz chip, but it's only the rough equivalent of a 60 MHz Pentium. -Tom
3009.3	Depends	TALLIS::NELSON	It's not the years it's the mileage!	`Tue May 13 1997 10:38`	16
	My dad and a couple folks at work here got great results with them. Specced out at about a Pentium 90, or just under. I, on the other hand, didn't have such great luck. I only saw a 30% improvement on the numbers over my 486-dx266. So I returned it. I would buy it from the place that has a full warranty on the part. I think I got it from MicroWarehouse. I only had to pay for shipping, the other $110 was returned in full. Another place I looked at that had the same price would have charged me 15% restocking fee. Brian
3009.4	Why it may be so!	SNOFS1::RASMUSSEN		`Tue May 13 1997 22:10`	16
	From my research into the AMD 5x86 -133 it appears that it will do an internal clock multiplier of 3 or 4 depending on the CLKMUL signal. On some motherboards (eg. DEC MTE & LPx) CLKMUL is left floating/high in this case the docs say you will get a x3 improvement ie. you will see roughly the same performance as expected from a DX4-100. When we see a x3 performance level we have tried to ground CLKMUL and hence, in theory, get a x4 but without success. We are still investigating but not at a high priority. Also please note that we are using a voltage convert plus AMD 5x86 and not a KINGSTON or EVERGREEN. Regards Wayne
