Overclocking AMD K6-2 300

[aratike]

I am just a rookie when it comes to overclocking, but I would like to give it a shot. I would like to overclock my HP 6330, slowly at first, to extract a bit more performance. I would guess that the 66mhz bus is going to be a limiting factor in any performance gains to be had. Can anyone provide me with some tips on how to get started? Thanks!

ok i have a k6-2 300. currently, i have it running at 75x5(375 mhz) but i dont think you would b able to go that far. i suggest geting some pc100 ram and trying it at 100 mhz bus and trying like 3.5x100(350 mhz)...it will be much faster than 4.5x66. also, if that doesn't work, try running at 75 and 83 mhz bus speeds, but make sure to get the pc100 ram first...it will run abtter at those bus speeds than the ram that came with the hp you have.

Hey Chad,
Man I know you posted that message a long time ago but I have an AMD K62 300Mhz and I want to overclock it. Can you give me any info, bro?
Thanks
Peace

Put some more information here: What bus speeds/multipliers and voltages are available on your motherboard?

[biggdogg]

How do you find out? (this is sorta new to me but I am a FAST learner) It's in a compaq presario 2256 and I am in the process of obtaing the info on the motherboard. Compaq is a pain in the but dealing with older systems.

Thanks.

[Dputiger]

Compaq should have all that information. If they'll it to you, we will be in business. Since your processor is a 300 Mhz I'm guessing your board can probably go to 75 or 83 Mhz FSB.

Since you've got a K6 I'm assuming your board is a 2.2 V K6. Also, if your bus speed is 66 than we know you have at least a 4.5x multiplier.

So you've got a few options. If your system has higher bus speeds we can probably get 337 Mhz.

The good news is that you've got another option if your motherboard has a 2x multiplier.

The AMD K6-2 400 has a 2x/6x multiplier remap. That means that if you can set your motherboard to a 2x it will automatically read as 6x. That will give you 400 Mhz (66*6). It's a substantial upgrade from 300 and will only cost you 30, 40 bucks.

Best of all, if your system is stable at higher bus speeds, you can probably squeeze 450 or 500 Mhz. I'd look into it.

[biggdogg]

Dputiger, do you mean that there is a processor upgrade to k6-2 400?

I just got the number to call for the manual, I should have it hopefully on wednesday (7/5/00)

Is there any way to find out the FSB info from within Windows (i.e. Compaq Diagnostics)?

Thanks!

Happy 4th....

[Dputiger]

I'm not sure. Sandra might tell you, but I don't know. At any rate, yes, there is an upgrade.

That upgrade I discussed will work on any mobo with a 2.2 voltage setting and a 2x/6x multiplier. Your machine seems to be almost identical to mine and this upgrade works well on mine.

If you can get your fsb to 75 or 83 you'd get a nice upgrade from that 400 chip. You could take it to 450 or even 500 depending on how stable your machine is at the higher fsb.

[biggdogg]

I'm on it. Thanks!

Ohh boy,

yet somebody else who has bought an HP pavilion.
No offense, but they are very bad.

If ya want to know anything, and I really mean anything, about your pc, ask me, where I work we produce those pavilions, or at least used to.

I have access to all the specs and partnumbers of those machines.
The max for the mobo, cpu and ram that is in there, type of mobo, I know it has a phoenix bios, very user unfriendly bios.
In the means of being able to change things that is.

Just let me know and I'll look first thing in the morning.

Hey Ultima!

I have a compaq presario 2256, though...

Do you know where I can get THAT info by any chance. I got a users manual for my compaq and it doesn't say ANYthing at all about the jumpers, but I'm still working on it.

ThanX!

[Ultima]

Hey Biggdogg,

I wish I could help you out, but we have never produced or recycled compaq machines.

Isn't there anything on their website???
I'll go and find out, I'll get back to you!!

Just a little patience.

Pim

Here's a link: might get something out of it:

DpuTiger, This is what I got so far but It's kinda all greek (Tee-Hee)...

____________________________________________
I'm sorry about the bad link but I did check it before I posted it.
All I came up with on bus speed is the External bus speed of 66Mhz.
2256 System Board: Core Voltage

233 MHz
JP1
Pin 1 - 2 Off
Pin 3 - 4 Off 266 MHz
Pin 5 - 6 Off Pin 1 - 2 On
Pin 3 - 4 Off 300 Mhz
Pin 5 - 6 On Pin 1 - 2 On
Pin 3 - 4 On
Pin 5 - 6 On
JP2 (For Clearing Cmos) Short 2&3
JP2 (Default Setting) Short 1&2
JP3 Short 5&6 (3.2 volts) All Open (2.2 volts)
JP4 All Open Short 3&4
------------------------------------
Go to this page and enter 2256 in model category, click on GO, then at the bottom of the page you will see QRG, click on that link. http://web14.compaq.com/falco/sp_presario.asp
Thank you for posting.

Thanks PIM...

Weird coincidence, huh. I just came from that very same page after I read your first post.

Is this the correct one http://members.spree.com/technology/brydon/compaq.jpg

[Dputiger]

Ohh, boy.

I hope you've got more info than just that clip. http://sysopt.earthweb.com/forum/smile.gif I'll check it out tomorrow--my computer doesn't have Adobe Acrobat, so I can't look at this PDF file (I'm on an old laptop currently).

[Brydon]

It all seems a bit confusing. I had an old presario 4118 and I found all the jumper settings were printed under the desktop case cover so open it up and have a look.

[Ultima]

I can tell ya right now Brydon,

HP doesn't print the jumpersettings anywhere in or outside the case.

HP pavilions are designed to only work as they are delivered.
The best change ya can get out of it, is memory adding or newer cpu.

Trust me, get yourself only a new mobo, and you'll have a nice puter, the mobo is the thing that is causing all the trouble.

Ohh, and if ya happen to have a riptide combicard in there, get it out, the worst there are.
They can cause all kind of fails.

I've seen puters here at work with memory fails, cpu fail, vga fail, you name it, and 6 out of 7 were fixed when the riptide was pulled out.

To me, that sounds like one crappy card.

[Brydon]

Sorry for the misunderstanding Ultima...I was replying to biggdogg about his Compaq. My friend has an old HP 133 and no matter what he did with the jumpers it would only run at slower speeds than 133 lol http://sysopt.earthweb.com/forum/smile.gif. I have been burned once having a Compaq and never again..self build rules http://sysopt.earthweb.com/forum/smile.gif.

[Dputiger]

Ok, Biggdogg, I got a look at your Compaq PDF file--that thing is WHACKED out and I'm having a hard time digging through it.

You're going to have to look at the board yourself and see if anything is written on it--a model number would be VERY helpful. Right now I'm assuming you've got a Compaq 4320 ES board since that's the only one that even lists a 300 Mhz CPU as possible. You'll have to check, though.

Let me know what you can find out. It looks like you might be able to use that 400 Mhz chip, but since your FSB doesn't look like it goes higher than 66, that 6*66 might be all you get.

Of course, going from 300 to 400 for 35 bucks or so is not bad.

[biggdogg]

Hey Tiger.

I was on the phone with compaq and they seem to think (lol) that this cpu is actually 266 ALREADY overclocked to 300.
Does that make any sense to you?

You need me to find out what kind of motherboard. correct?

I'll open it up.

Thanks!

[Dputiger]

Actually, yes, it does--though I'm stunned they'd admit it on the phone.

When AMD's K6 line first came out the chip #'s were not etched on the face on the chip in metal but were painted on. They were absurdedly easy to change and a huge market was born in K6-300's that were, in fact, just OCced 233's.

AMD realized this and started etching their processors.

I need anything you can pull off that motherboard that looks like a jumper map, multiplier settings, a model number, etc.
