Socket 7 mother board P530-B4 question

Was wondering if there are any places to find a modified BIOS that allows the use of a higher end K6 or Celeron processor for this board. It tops out at K6 300. I was hoping something was available.

Thanks for any info

 
While there are tweaked BIOSes for a lot of boards, I would not suggest using one which increases the top speed processor that you can use. If the manufacturer doesn't have a new BIOS that supports faster processors, then you're probably SOL.

Celeron is also incompatible with Socket7. You will only be able to use the Pentium, PentiumMMX, K6, K6-2, K6-III, or Cyrix 6x86 or M2 processors. (And many of those require that your motherboard maker have made the BIOS work for them.) Check with the manufacturer. See if they have a BIOS that supports the K6-2 and K6-III line. If they do, then you can update it to that BIOS and get a bit of a boost. A K6-2/400 is only 20 dollars on Pricewatch. (You may be limited in the speed you can get out of it no matter what, unless you overclock the frontside-bus. The K6-2 and III interpret the 2X multiplier as 6X, so on a 66MHz bus you can get 400MHz. If your board supports higher bus speeds then you can overclock the FSB and use a faster rated processor, but it's not suggested that you attempt overclocking a K6 series processor, they don't do it well.)
 
I found the manufacturer's page and it looks like the last BIOS revision was in 98, I was hoping someone had modified the BIOS to include some of the faster chips because it looks like the board could support them.


Here's the link to the boards infoText

Have any idea where I might find a page that could steer me in the right direction?

This system I have here is not worth much so taking a chance on it is fine with me.
 
If you look deeper, you find that the board can support a K6-2 up to 366MHz, if it's revision 1.4.

I would NOT expect anybody to have hacked a reliable BIOS for any motherboard which supports a completely different type of processor. If they were able to do that, they'd be working for the BIOS/board makers already. 🙂 I certainly wouldn't just throw away a working board to try out a hacked BIOS that makes that huge a change. (I'm using a hacked BIOS on my own system right now, but all it does is allow different bus speeds.)
 
Hmm, at post it reads

TRM-P5T30B4-V.1.07

Not sure if I can get to revision 1.4 the latest BIOS reads 1.12 so I don't think that's it.

Is this revision number on the system board itself?

Thanks for all the help


 
Looked at the page again, the K6-2 266 runs at 66mhz bus and 2.2 /3.3 this would seem to work on the 1.2 board.

If it did, would this processor run faster than the K6 300?

Just curious
 
Even though the board could accept it electrically, the BIOS and other factors like capacitors and MOSFETs will prevent it from working. Probably best not to try it unless you've already got a K6-2 laying around or don't mind paying for one and risking frying it. (probably cheap, but even Pricewatch doesn't list anything under 400MHz.)
 
From what I understand the K6II reads the 2x multiplyer as 6x. My old box is running an AMD K6II 450 @ 6x83MHz = 498MHz.

I think most socket 7 boards will run at least 2x (6x) x 66MHz = 396MHz. The K6II should run on any board that supports the K6, although some of the onboard cache memory read/write functions might not be supported. There are programs (SetK6 ?) that can help with this. The only posible problem might be the cpu voltage, if I remember correctly your motherboard must go down to 2.2V.

Sorry if the details are a bit foggy, but it has been a while since I worked on my old K6II system. It is still running as the kids computer now. It can even run Counter-Strike fairly well with the Voodoo3-2000 video card. It has a piece of junk PCChips M575 motherboard, just for reference.

Good Luck
 
The systemboard/mainboard/motherboard/etc.. that I have does indeed go to 2.2v, so is a K6 2 266 faster then a K6 300?

 
I think when the vendor specifies that revision 1.4 can use a K6-2, but revision 1.2 can't, I'd listen to them instead of assuming anything. NOT all Socket7 boards can use a K6-2 processor.
