K6-III+ / K6-2+ on an Asus P5A

[Tanked]

Ok, I'm getting a little despirate here...I've been using a MVP3 motherboard with horrible graphics support, and I finally got an Asus P5A Aladdin5 board with a new BIOS.
Everything seemed to run fine...The motherboard identified it as a K6-III (normal), it booted up, everything looked great...then I ran SiSoft, and my ALU / FPU scores were around a dismal 200 points each.
I tried a K6-2 Processor and it runs fine...I called Asus, they offered no help. Does anyone else either have this combination or know of a workaround?

Help would be greatly appreciated.

The board should run a K6-2+ or a K6-3+ just fine (except for the last revision of the motherboard I believe).

It won''t identify the cpu as a plus, but it will work just fine. Are you sure you have the very latest BIOS?

I got the Beta BIOS, the latest one, simply because the original one didn't even identify the K6-III and it wouldn't support hard drives over 32 GB.
"Except the last revision"... would that mean Revision 1.06? :-(

I honestly can't remember - it's been too long since I have dealt with Super-7, but I think that rev 1.5 and up give trouble with the plus series of cpu's.

I have a P5A w/ 500MHz K6-2. Actually, it's in a box now.....I've upgraded. What kind of numbers did you expect? Does the computer run fine? Does it "feel" like it's running at the right speed?

 

[Tanked]

It feels (and benchmarks) just fine with my K6-2 333, but when I tried my K6-III+, You could tell something was wrong. Quake III wouldn't run, SiSoft recorded scores of about 200 points in both the Dhrystone and Whetstone. Memory scores were the same between both CPUs.

Something is wrong. On this system, an ASUS P/I-P55T2P4 Intel HX chipset mobo with a K6-3+ 450 @ 450, I get 1082 ALU/ 552 FPU. This is an OLD mobo with EDO ram.

Ok, I think im going to kill myself....
On another page, reinforcing a previous post, it states "P5A Boards, revision 1.5 and 1.6, will run extremely slow on a K6-Plus CPU from an unknown hardware problem"...
:-(

 

[oldfart]

Bummer. The K6-3+ is a sweet little CPU (and very hard to find). Too bad you cant get a decent mobo for it.

That sucks, K6-3/2+ are great CPU's! Too bad!

Did you try asking for help @ the K6-X forum?

I'm running a AMD K 6-3+ 450 on a P5A-B. Maybe you could get one of those cheaply?

I also remember something about a Microsoft patch that fixed a problem I had running a K-6. I'll see if I can find it and see if it is related. Maybe you can search the MS site. I am running Win Me.

The patch cured my timing problem. Don't know if it has anything to do with your problem.

Thanks for the help guys, I visited the K6-X Forum, hopefully they might a bit of insight on it too...
Did that K6 patch from Microsoft fix your P5A-B problem? If it did, im getting it

 

[kjacobs]

Yes it did but this was for an error I got booting up. And it only happened 50% of the time which was causing frustration. Hope it will help you. It really is an obscure patch!

 

[oldfart]

Isn't that patch just for Win95?

I used to have a k6-3 400 on a P5A and I have the Sandra results in a txt file saved. PM me with your e-mail if you want it. I don't have it anymore so I can't do any more tests.
