MMX200 VS K6 500 and V503+

Hi ppl,I have a friend wich has a k6-2 (I think) 500 will this better than my 200@250?I am asking this cuz my cousin bring his computer here one day (Via mvp3 board,160/192 ram,tnt2 m64,20gb hdd,etc) and in that time my system (p200mmx@250,10gb hdd,2xvoodoo 2 SLI,128ram) got much more fps in ut than his...his computer was formated put the "latest" drivers for his things..updated the d3d and opengl drrivers for ut..and still less fps than mine...
and about my board the va503+ how high is it multiplyers?anyone did good ocs with this board?I can't past 250mhz I don't know why..tried differente multis..raising the voltage..different fsbs..but nothing..

skinnie, you are doing just fine with oc'ing the p200 to 250mhz! that is a rather good result for a p200.

your mainboard is ready to support 5.5x multiplier. CXT-core K6 cpus (up from 400mzh, some 350 are also cxt-core) have a built-in clock multiplier, i.e. if your motherboard is setup for 2x, the cpu translates it into 6x.

regarding your higher fps in ut: I think it is due to your 2 voodoos (compared with the tnt2) and that ut stresses more the graphics card than the cpu.

if I will buy (sorry my bad english) a k6 it will be that k6 500 because the guy may sell it to me @2eur!!lol

I've run a Pentium MMX 233 at 300 MHz (3x100) in a VA503

. Watch the thing blow away Pentium IIs lol.

A K6-2 @ 500 will dust a Pentium MMX big time though, even a 300 MHz one. It's a generation ahead with a bigger L1 cache and 3DNow.

For Unreal-engined games you absolutely want a Voodoo card cuz Glide has less CPU overhead, and that means a lot on a Super 7 system with their poor FPUs. Unreal doesn't use much 3DNow either from what I've read.

ppl my friend gave me is k6..it is a k6-II 500AFX 2.2v core 3.3v i/o 0014MPM is this any good?in the board I put what?2.2v?

2.2 v will work w/ that processor until you start to raise the multiplier up to 5.5. For 5.5 x 100 you should raise the voltage to 2.3v. It is also possible to go up to 600 Mhz with that kind of processor; but heat becomes an issue up there; and you should get advise from someone who has done it, (NOT ME), before you try that to prevent damage to it or your mobo.

I tried 5.5 x100@2.2 it gives a windows protection error,2.3 itgives a bsod,2.4,it wont pass from the second screen (after post) :S can it be a bios issue?

Not sure. Could be the timings are too aggressive for the RAM you have installed. FICs are known to be picky about RAM. (Top quality is what they like) Could also be that 1 or more of your caps is starting to go bad. Could also be a heat issue, if you don't have thermal transfer compound on your heatsink of if the fan/heatsink combo is too small for overclocking.

maybe it is the ram..but explain me one thing..I can approach 100x2.5 with that timigns on my mmx200 and in the amd I can't do 100x5.5 because of the timings too??!?
I'll try to put it on it's deafutl 3-3-3-8...in the jumpers should I put pc100 or not pc100,sicne both sticks are pc133?
The cooler is good I think and it has a pentium 3 1000 fan on it..and it has as5 but it was put very badly..

K6-2's are not the best of overclockers. You could try 5.5x95 fsb first to see if it will get to 523MHz. If it gets there try running it for a while at that speed before trying 550MHz. If you have 97MHZ fsb you could try for 533MHz, but not all boards support this frequency setting.

You didn't mention your O/S. Older versions of Windows (95) needed a patch to run K6 chips faster than 350 MHz.

Here's a link

other than that, yeah...K6 chips weren't exactly known for their overclocking.

I have 98 se with all upgrades..maybe it is bad cooling or the timings..

Jim · Post by **Jim** » Wed Sep 27, 2006 11:12 pm

I would try setting the ram at the PC100 setting. I thing the Not PC 100 was intended to support older ram, and that PC133 had not yet been invented at the time those boards were designed, though I could be wrong. Also it is possible that your processor is one of those that can't cut it at 550, though if it were me, I'd give it every chance to. i.e. make sure you have the heat sink properly mounted and the thermal compound properly applied, and beg or borrow some quality ram to try before giving up on the processor. Tazwegion got his up to 600, though I think he had to decap it to do it. Also check the mobo for electrolytic capacitors that are not perfectly flat across their tops. If any look like they are beginning to "Round" at the top, your mobo has the "Capacitor Problem".

Also Stedman is right. Try going for 5.5x95 and see what that does. You should be able to do that @ 2.2v. If you can't, then I don't think the problem is the processor.

EDIT : Overlooking the obvious here too. Your bios has 2 sets of defaults in it, one for speed and one for minimal stress. Load the minimal stress defaults and see if that enables you to get up to 550 MHz. If it does, then go back into the bios and reset the settings to their performance setting 1 at a time, each time testing to see if the machine will still operate at 550 without problems. When you encounter a setting that causes problems when enabled, leave it disabled and go on to the next one. Keep on doing that till you have gone through all the settings and have found which ones you can enable that will allow your machine to work at 550.

I talk to the previous owner and he told me that this proc "eats" voltage...he said that him and the other previous owner run it @2.8v..so I think that is the problem..I don't care no more..even@500 i'll do with tha proc what I do with my mmx200...I only do it better...
Here in portugal it is very rare to see "quality" sdram most are oem..and they are very expensive..

You also have the choice of not being so aggressive with the CPU. Try clocking it at 300 MHz, then 350, and so on...until the system becomes unstable.

Every MHz counts...even if it is only a slight bit.
