I collected my K6's over 10 years ago and have quite a collection. Lost count really, but some from what I remember are below. K6-III 333, 4 of 400, 2 450AFX and 2 450AHX. Fastest I got on air was 500 out the 450AFX's K6-2+ 400ACR, 400ATX, 4 of 500ACZ, 2 of 550ACZ K6-III+ 400ATX, 4 of 450ACZ, 1 of …

I have this board and it overclocks really well with a celeron 1300 or a 1200 that I have. The OXET board has pll settings in bios to adjust the fsb whilst keeping the pci bus fixed at 33. The celeron 1300 runs at 1733Mhz with 133fsb on air with the pci bus at 33 using the correct pll setting. …

I have a Gigabyte GA 6OXET motherboard and have a number of Celeron Tualatins. The 1300MHz Tualeron CPU that I have runs comfortably at 1733MHz on air at 133 fsb with the pci bus running at normal speed with the 1/4 pll divider that is available on this board. Even at 1733Mhz the Tualatin Celeron …

This board may be able to run at 133Mhz fsb. The option may be available inside the bios set up for the board. It is not available by jumpers on the board itself. I have a Gigabyte GA 5SMM board and that runs at 133Mhz fsb no problem with a K63+ cpu. So 133 with a 4.5x multiplier. Also the memory …

Surely the question should be is there a better cpu I can use for my Asus P5-99VM motherboard. Of coarse there is. This motherboard is capable of running a K6 plus cpu at 600MHz and most likely at an fsb of 133Mhz. The SIS530 chipset unofficially supports an fsb of 133 with a 1/4 divider. So the PCI …

I did the same mod to my 1.06 board with a 1k resistor. I have found the same issue with regards to the voltage. At 2.0v the system will not boot with a K6-2+550. At 2.1v the system does boot up. Have also found that the memory performance is still not giving the same figures as the 1.04 board using …

For benchmarks try superpi 1M. Also look at the Everest MR/MW/ML for the memory subsystem. Bios settings and WPCREDIT adjustments can help with getting the best performance out of your system. You should find some help on the K6plus site. For the bog standard K6-III+ cpu running at 550MHz on the P5A …

Question After looking at the spec sheet for the cpu I presume that you can use any of the many vcc3 pins that are available on the cpu pin layout.

Hi, I am no electronics whizz, but are you saying that you just have to solder a 1 k ohm resistor to bridge the 2 cpu socket pins you have outlined above. If so that would be great news. I have P5A versions 1.05, 1.06 and 1.04. So I could test the relevance of activating the defective chipset tagram …

Hi Skyscraper, To get good results in superpi you will have to apply the WPCREDIT tweaks as it improves memory bandwidth considerably. Can you currently run your board with 133MHz fsb with your K6+ chip as some seem to be flakey at this speed. I have beaten the 4m 44s barrier with using an Epox EP …

Might be wrong, but I think the Abit KT7A raid had an ISA slot. Should be about as good as you can get with an athlon cpu. Might support up to an XP2600+. Certainly it supported the Palamino Athlons up to XP2100+

I have the MSI 694T PRO v5.0 and it works fine and overclocks well enough up to 150Mz fsb. The last BIOS update recognises a Tualatin P-IIIs 1266MHz correctly but not a P-IIIs 1400Mhz. However it still runs fine with a P-IIIs 1400 in it. I just find it irritating when the splash screen comes up …
