Putting K6-2+ on ASUS P5A - Ali V MoBo: I need a manual for this board

[Herkulese]

OK, I am ready flash the BIOS to this P5A ver 1.04 MoBo to the 1011 beta 004 ver. and then install the K6-2+ 450 CPU.
I went to the ASUS sight to find the manual for the board, but it is not there.
Does anyone know where to download a manual for this board or can you give me the jumper settings for Voltages (2.0, 2.1, 2.2) and multipliers (4.5, 5.0, 5.5, 6.0) and/or any other info required for this setup?

DieHardware,

Thanks for the link to the ASUS Jumper Page.
How did you find thie page?
I could not come up with it anywhere.

Questions:
1) I notice that all of the settings required for a K6-2+ are already present. Is the 1011 beta 004 BIOS required for proper recognition of the + chip?
2) With the TYAN S1590 the 2.1c/v setting does not work properly. Do the 2.0c/v and 2.1c/v settings hold stable on this board?
3) If I update to the 1011 bata 004 bios, set the Jumpers for 4.5x, 5x, 5.5x, 6x / 100mhz FSB / and 2.0 or 2.1c/v, should the K6-2+ 450 run?
4) Do I need to clear C-Moss prior to updating the BIOS to the 1011 beta 004 BIOS?

k6-2+ will work with some bioses below that, but I'm not sure which ones now.

You don't need to clear the bios when you flash, but if the voltage is stable is entirely up to the chip. You have to run and test it yourself.

Sorry, never tried a K6-2+(couldn't find one). P5A manual in PDF format Click on the PDF to download the manual.

"orry, never tried a K6-2+(couldn't find one"/i]

Tiger Direct has the K6-2+ 450 for $35.00 plus shipping.

This manual file is named P5A 1.07. Does that mean it is for the version 1.07 Board or Manual?
My board is version 1.04.

What are these k62 + chips? I heard about them, something about them being for laptops??
What makes these so special?

 

[DieHardware]

Full speed cache in the CPU's core.

The maximum speed K62 plus they made was what? 450? Can they be overclocked high?

 

[garyboz]

Yes, they can be clocked pretty high, especially high for a K6 chip. I had 2.2 and 2.4 volt K6-III 450's, neither of which would do 500 MHz. I had 3 K6-2+ 450's all of which would do 575 MHz and one which would do 577 (575 was actually faster) but it wouldn't do 600 MHz, not even at 2.6 volts.

Get a Thermaltake Volcano II fan for it. It fits just within the caps around the socket and runs about $8 or so. I've have seen people get 615+ MHz with this chip. I've been thinking lately that my inability to get 600+ is because of an inadequate power supply but I haven't had an opportunity to test this. I was using an Antec but it only has 135 combined power. I also had trouble getting the FSB up above 115 despite using PC133.

Get a Geforce 2 MX fot this setup. I was getting 40+ FPS in Q3 @ 1024x768x32 with all options on. I stuck a Geforce2 GTS in there but didn't get any increase.

 

[Mavrick007]

garyboz: So would you suggest getting a k62 450+ over just a K62 533 or K62 550?? I'm curious why people would get the 450 is all. I have seen the 533Mhz go for like $28 bucks lately on pricewatch.

Go to the following link and read up on the difference between K6 and K6+ chips.

Read this thread

 

[AA0]

the on die cache is a nice thing.
They can be overclocked but 600 seems to be about the top speed.
The reason for the heat difference is that the +s are made with a .18micron tech, while normal k6s were made on .25. Since they are using the same size transistors as the Tbirds and XPs, they run a lot cooler, mine was around 30C, about the same as my board temp.

 

[Mavrick007]

I'm just surprised that I couldn't find anything out on Asus' site about the K62plus except that it was meant for moble cpus.
Hmmm I'm thinking about upgrading the old machine with the k62plus now. I wish I could find more of these k63plus ones or the higher speed ones. The best I can find for sale now is the k62plus 450 like you showed on that Tiger Direct site.

What do you usually have to set your VIO voltage at?

 

[Herkulese]

Mavrick,

The K6-2+ can be found at Tigar Direct for $35 plus shipping.

The K6-3+ is tough to find, and the last time I saw them (more than a month ago) they were selling for around $100, or more.

 

[garyboz]

Mavrick007, the K6-2+ has 128K on die cache running at full clock speed. A 450+ will probably be as fast or faster than a regular 550 (Although that will depend on what type of benchmark you are running.) Now if you can overclock the 2+ to 550 it will blow the regular chip out of the water. You need a motherboard that will support it, you'll need to do a websearch and see if other people are using it with you're motherboard. I've put them in Asus P5A's rev 1.04 and below and in Tekram P5T30-B4. You're putting a chip designed for a notebook into a PC. Nobody will say that that will tell you that is supported. It's like calling Ford and saying, "Hey I wrecked my F150 but the engine is fine. Can you tell me how to put the engine in my Escort?" It may be possible but they don't want to be responsible if anything bad happens. That's why you need to do a search and see if other people are using a 2+ with your motherboard. Just set the voltage at 2.0 or 2.2 volts with a big heatsink.

 

[Mavrick007]

garyboz: The reason I was inquiring here in the first start was cause my mobo is the Asus P5a as well and I wanted more info on the K62+. I think it's revision 1.04 or 1.03, it's been awhile since I looked. I was just thinking about the k62+ 450 and putting it up to 550, 600 or above if possible cause the board will do up to 120fsb(but I've heard some people comment about 133 but I'm not sure how that's possible).

Hehe It's more of an experimental project cause I'm curious how fast I can get this older socket 7 board to go. I don't think anyone would have expected basically the "pentium" generation, much less AMD to go above 300Mhz, let alone double that. I would never pay $100 for a K63+ or anything that old Herkulese, but it would be nice to see how far you could take it. I think that if I can get the chip going well at 550 or 600, I will eventually just use it as a server. I'd hate to sell something that I put so much effort into even though some machines would kill it nowadays.

I have an XP system too and have had AMD's since the 486. Right now I'm in the process of making my first Intel machine(off of the P4 1.6a) since my old P166.

Mavrick,

"I was just thinking about the k62+ 450 and putting it up to 550, 600 or above if possible cause the board will do up to 120fsb(but I've heard some people comment about 133 but I'm not sure how that's possible)."

If your board is ver 1.04 or older you should be OK with the K6-2+.

You will need to go and get the 1011 beta 004 bios update Here.
Clear the CMOSS, load BIOS defaults, then run Flash the new BIOS.

With this bios the board shouls correctly recognize the + CPU.

You do not need to go out of speck with the FSB if you do not wish to.
You can get to 500 and 550 by setting the multiplier at 100fsb x 5 or 5.5. You can get to 600 by setting the mult at 100fsb x 6

- - -You get 6x by using the 2x mult, as it will now be maped to 6x. - - -

Set the voltage to 2.0, 2.1 or 2.2 and you should be good to go.
Remember, these CPU's use a thinner (.18) core and are ment to use 1.8 to 1.9 volts.

I hope that this helps

 

[Mavrick007]

I have the bios 1011 beta 002 right now I think. I know my revision is 1.04 or possibly 1.03 cause I had a problem with the AGP slot not getting enough power and it was supposedly on 1.04 and before.

Would the K62+ work on my bios too? Or would it just work on the beta 004 bios?

 

[Mavrick007]

Hey, I found a K63 450+ cpu on pricewatch for $69US. I'm sure the k62+ is just as good, maybe a small bit slower and easier to overclock too I bet. Opinions?

 

[garyboz]

The 3+ has twice the on die cache as the 2+ . More=Better. It will be faster at stock speeds but I think more people have had luck overclocking the 2+ (of course they sold a lot more of the 2+).

Don't count on getting 120 or 133 bus speeds. The only usefull 120MHz setting is 600 MHz (Unless your chip will do 660MHz). I couldn't get 600MHz stable, not even at 2.6 volts. I also couldn't get 133MHz to work at any setting despite using PC133. I used 115x5.

 

[Mavrick007]

yep, that's just like the normal K63's, 256k on-die cache, but I would bet that the K62 450+ can overclock a bit better and it's like half the price of the k63 450+. That's a much better deal on something that isn't going to give me as much as a fast Duron would. I would rather put the 1G Duron on a board for $45 than spend $69 on a K63+.

I'll post something when/if I get a k62 450+. Thanx for the info guys.
