Pentium 233mmx

[berkeljm]

Well, I got a new motherboard and a k6-III 450 processor. The board is a Soyo (not my first choice, but it was free). It supports many FSB's which include 100, 112, 124. Nothing above 100 FSB will work. The clock multiplier goes to 5.5 but again......nothing above 4.5 will work. The voltage settings on the board are funky in how it was designed. You can't increase by increments. It is labeled by processor. So without some serious guess work I can't change it to 2.5.....or 2.6. In reply to your post, I'm not sure what you are trying to say. I think you were saying..........get a new motherboard. Well, I did and that didn't help. Although there is a significant increase in performance compared to the other board.......even though soyo boards suck.

Here is what I have now.

AMD K6-III 450
Soyo 5EMA+ Super 7 MOBO
384 Meg PC100 Kingston SDRAM
Hercules Prophet II MX
WIN98 SE
6.4 gig HDD
4 gig HDD
50X Acer CD-Rom
56k UsRobotics
Predator 4D Wave sound card

It's a good upgrade from the crap I had before.....not the best but I couldn't beat the price. I upgraded the Mobo, Pocessor, and Video card all for $160.00. Not a bad price considering the video card. It is also the retail version.....not OEM so the clock and memory of the video card 175/183 (stock). All the other parts I had already. Being a Network Administrator at a large company has it's percs. Good contacts.

LOL, ok you ae going to have to settle for 450, the k6-3's big weakness is it is not very overclockable at all. The slower ones (350 and 400) have some headroom but the 450 just won;t do a whole lot more. The additional 256 level 2 cache that makes it so much better than the k6-2's is the culprit, it just cant take the higher freq. If I knew you were going to go the new mobo route I would have suggested something all together differnt though. What did you pay for the 450?

A little bit of knowledge is a dangerous thing!

 

[berkeljm]

Well, actually I got the Mobo for free......and the CPU. I "had" to buy a new video card which is SO much better than the last one (Hercules Prophet II MX), and a new ATX case. It cost me about $200.00 for all 4 things. Not bad. I would have prefered to get a Thunderbird CPU but then I would have had to buy a new board and CPU versus.......uuummmmm........free. I am a Network Administrator so the perc's are nice. Good contacts and first dibs on hardware they are getting rid of. I should have gone this route a while ago but I wanted to see if there was a way to overclock a Pentium I 233 past 266 on the board that I had. I'm sure with a new board that actually supported 83mhz it would do 290. I can't justify buying a new board for that processor.......so unless I get my hands on another free board then it will just have to sit for now. It wasn't going to happen so I decided to jump at the mostly free route.

how about keep the proc. as a <b><font color=green>CPU upgrade roadmap</font color=green></b> for your own reference ?! 😎

"Then again, there's also that FPU. There's no doubt a Pentium MMX at 300 would beat a K6 300 in that department."

No way the Pmmx even @ 350 could touch the FPU of a K6/k6-2 The K6 was against the P2. Now a K5 would get its ass kicked.

soup.

AMD for Life!

wrong, the K6 fpu wasn't comparable to the Pentium, much less the PII. it was the integer performance that was good. 3dnow helped alot when supported.
If the K6 Fpu was comparable to the PII it would still be produced at higher frequencies.

Dammit I've got a multiplier locked pentium mmx running at 3X83 Mhz, it is rock stable, but when I use fdisk or partition magic, it screws the partitions up unless I run it with 75 Mhz bus or lower. A friend of mine has a Pentium MMX running at 200 (default speed), and it is not multiplier locked, once I overclocked it to 233 Mhz, when I didn't even know what overclocking was, now if wonder if he would like to change his processor with mine...

 

[berkeljm]

What processor is it? What is the default speed? Why do you need to use partition magic? I would not recomend it. It (most of the time) causes more problems than it's worth. It would work great on a "within spec" PC but when you start to overclock specialty software you are asking for problems no matter what. If the board is too old to support the size hard drive that you have I am surprised that it will run 83mhz FSB. Of course, I don't know what drive you have but it should work unless you are trying to use something larger than an 8 gig drive........depending on the motherboard.

I've got a Pentium 200 Mhz MMX, it is a very good chip, it overclocks to 225 Mhz with default voltage (2.8 V), and... works properly @ 225 with just 2.5 V, so I suppose it is a good sample, but it is multiplier locked and doesn't allow me to choose the x3.5 multiplier. I've got a QDI Titanium IB mobo. It does support 83 Mhz bus via a beta bios update. My HD is a 8.4 GB Seagate, it should work properly because the bios supports drives bigger than 8 GB. The partition issue happens no matter of Ultra DMA being enabled or disabled. Could it be that the PCI IDE controller does not support 41.5 MHz?

 

[berkeljm]

When you say that it screws up the partition...what exactly do you mean? The controller may not be able to handle being overclocked. Try setting it to PIO Mode 3 or 4. I would try (maybe even start at 2) 3 first and then work your way up if you don't get any problems. You should be able to disable and enable UDMA and still ajust the PIO Mode. Keep in mind that when you overclock the FSB.....you are overclocking EVERYTHING on the motherboard. This includes the controllers, memory bus, PCI, ISA, and AGP (if you have it)........among other things.

Some people claim (acording to their measurments) that k6-2 have faster fpu. Only that some programs optimised for pentium fpu.
P.S. My P233-MMX was runing at 262@75 , now it 250@83 (still testing).
Not hot at all. i also don't have any problems with video.
I am worrying about sound blaster, some transistors on it is too hot to touch, and sometimes windows saz that soundblaster gone.


All i can offer you is the truth. Nothing more.

 

[74merc]

well, that brings us to the same point we have with the P4. If the software isn't optimized for it, it doesn't work as well, whether its stronger or not. I'm sure SSE2 will kick ***, but until it is mainstream, I'm not touchin a P4.
Anyway, the software will not be optimized for a K6-2 FPU now, nor has it been, so the point is moot anyway.
now 3dnow is another can of worms...
btw, me thinks yer blaster is gonna buy the big one... Windows not recognizing it aint a good sign...

the k6 has about 50% the fpu of a p5 (the first pentiums were called p5=586 p6=686=ppro) when the k6-2 came out it had 3d now which is the floating point version of mmx.
everybody made fun of the software fix for a fpu short comming. odd that no one is laughing that the p4 is doing the same thing! matter of fact the PIII did it (sse) to keep up with the athlon's fpu.
any way back to the k6.
it has about a 95% hit rate on branch prediction! most struggle to hit 90%.
and yes the integer was strong enough to give an equally clocked PII a run for the money.
the main down fall was that k6 & k6-2 l2 cache was limited to 100mhz.

who is more foolish...
the fool, or the fool that takes his advice?
