I currently own a K6III 400 on an Asus P5A board. I was wondering if anyone knows where I can find the new K6III+ (around 500 mHz)? I know that Tom said they were nearly impossible to find, but I'm sure someone out there is selling them.

Any tips on who sells them are really appreciated

Hey,

I hate to be the bearer of Bad news but the "+" series of the K6-2 and K6-3 are mobile processors, only available for notebooks. You won't be getting one for a desktop. If you want a fairly inexpensive upgrade, and overcloackability, go with a Duron.

Pricewatch.com has listings for the K6-III+ upto 450mhz and they are less expensive than the K6-III processors.

:cool: TW

As a previous poster said, if you look on Pricewatch you will find them. Not in huge numbers but also not particualarly dificult to find. You have to search under the K6-III listing which will bring up both the original K6-III as well as the K6-III+ listings. The listings also seem to come and go quickly. I ordered mine from a company called Axion Technologies who only had them listed for about 2 days - but I got my K6-III+ 450 for $42.95 + shipping! Bottom line is that they are not as available as many more commonplace CPU's but if you want one you can definitely find one with a little effort.

On my Tyan 1598 MB, my 450 immediatly became a 550 with no special cooling and without even increasing the voltage! 600 seems to want better cooling than my standard heatsink and fan so I elected to just stay with 550. Afterall the whole point of this upgrade was to be a CHEAP interim solution.

Hey,

In ana earlier post of mine I stated that the K6-3 was only mobile, it was initially, and I wasn't aware that AMD started making desktop "+" processors. It does appear they are quiete rare, but price watch has them listed.

Thanks for the info. It sounds like they handle overclocking better than the original K6 III (Yea, I can finally put that Alpha to good use). I been checking on Pricewatch, but all I spotted were regular K6 III. Now that it seems they're in the end of the list, I'll scroll through them some more.

Thanks for the tips

I'm sorry, but you are wrong. There are small amounts of K6-III+ processors available for the DYI market and they are _very_ successful in desktop super7 systems. If you want more proof, check out the AmdZone forum <A HREF="http://www.amdzone.com/forum/categories.cfm?catid=13" target="_new">here</A>, which has been almost exclusively dedicated to K6-X+ processor usage in desktop systems recently.

Hey,

I never said they weren't succesful since I owned both a K6-2, and K6-3. I mereley stated that the K6 series weren't good for overclocking. While it is probable they are overclockable, more people have trouble doing so.

I bought (2) K6-3+450 chips from www.pcliquidators.com for $102 shipped to my door. Both are running rock stable with WIN 98 on Soyo 5EHM boards at 560mhz.

sorry guys but where do you get your info ?
these chips(k6-3+ & k6-2+)are all over the place!
i got mine(k6-3+ 450) from ebay $46 alot cheeper than the regular k63 and a hell of alot better!!
it runs great on a fic 503A(tom needs to put this board in his colum)i run it at 600 2x X 100 =600 and at 2.1V with no special cooling and it never goes over 30C now i did need to flash the bios from jn412 to jn4116 to get it to work but with the bios flash it booted the first time at 600 and has given me no problems at all ever since!!
this chip is a great improvement over my old k62-500
and 2.1V will not hurt it!!

here are some benchmarks:

sandra,
k62-500 cpu=1044 k63+@600=1444
fpu=616 fpu=731
mmx=1213 mmx=1443
floting point=1787 fp=2127
alu mem=111 alumem=142
fpu mem=127 fpu mem=151


3d mark 2000, default bench

k62-500 3dmark=1436 k63+@600=3786
cpu marks=124 cpu marks=227


quake timedemo, 6x8x32x32xmedxtri,and fsaa2x2
k62-500= 27.9fps k63+@600= 44.7

not that bad for a cheep upgrade the best money ive spent on this system yet!!

i wish tom would do a review on the fic 503A MB.

What are the performance differences form the K6-3 450 and the K6-3+ 500?

the k63+ has smaller die,.18 and more 3dnow instructions,runs cooler ,and will overclock very well.
but overall if you have a k6-3 450 the gain will not be that much more with a k63+ ,but if you have a k62-500 the gain will be great!!
also your mainboard has to support the k6+ chip to work .

mobile k6-3+ is the same cpu that we are using in desktop machines. Only real diff between mobile cpu and desktop is inclusion of powernow (inoperative mostlyin desktop systems), if motherboard supports it well it will perform 100% same as k6-3 (extra 3dnow instructions make little diff). K6-3+ does not work in all motherboards - asus p5a does support but maybe not very well - check out amdforum (k6-x) and asus newsgroup for info on asus board - i think there has been discussions about some people getting poor performance.
overclocking - basically nearly all will do 550-560 without voltage increase (default 2.0v). 600 is however not 100% sure. But 600-620 remain a chance. Highest recorded is 744 (not air cooled i am sure).

"..if motherboard supports it well it will perform 100% same as k6-3.."

True, but as you pointed out, most K63+ 450's will do at least 550. My experience with the original K63 was that you were lucky if you could get it to overclock at all.

You can get K6-2+ and K6-3+ CPU's at http://www.tigerdirect.com
I picked up a K6-3+ 450 for $49. I have it OC'd to 500 mhz on an DFI K6XV3+ atx Mobo. I believe It will go 550 or more with a good Sink and Fan.
This is a great way to add some longevity to your S7 Mobo for a very small investment.

the k6-3+ is a good overclocking i upgraded my old system. i got a k6-3+ to 750mhz pretty stable i might post some benchmarks. k6-3+ 750 vs tbird 750
