PK 7 1800 at 1.54 Ghz overclock...

Specs: Windows XP Professional, SP3, AMD Pk 7 1800+ @ 1.54 Ghz/ 768 MB
In case you didn't pay attention to my name, I'm an OC newbie. I need to know if there is any way to get any more life out of this poor 1.54 Ghz through BIOS, apps, etc. Has 768 MB RAM, Windows XP Pro SP3. Detailed answers, please and thanks.

Can't help you unless you post the exact make/model of your motherboard. Some boards are overclockable, others are not. If you have an OEM system (Dell, HP, Gateway, etc), it's not gonna happen.

NP, I know it's a DIT computer, with what seems to be an unlocked BIOS, cause I can change RAM frequency, voltage, etc. However, I can't change the FSB, it is greyed out at 133Mhz. I can't find the setting for the multiplier, either. What should I do? And how do I find mobo brand? (BTW, my RAM is set to 166 MHz, and system is running at 48C.)

Just to follow up, the 1.49 Ghz I've got, I've Oced to 1.6 Ghz, using a setting in BIOS, (I think is was clock frequency, but I don't remember atm) I set it to 139, cause, if I do 140, the system refuses to boot.

"my RAM is set to 166 MHz"

The RAM is supposed to run at the same frequency as the CPU (1:1 ratio). You're actually losing performance with the ratio at 133:166 (4:5) . Change the RAM speed to 133MHz.

Chances are the CPU multiplier is locked. Some of the early AXP 1800+ were unlocked but the vast majority are locked.

"the 1.49 Ghz I've got, I've Oced to 1.6 Ghz"

What's a 1.49GHz? AMD didn't make any CPUs that run at that speed. It's either 1.47GHz (1700+) or 1.53GHz (1800+). If you got it up to 1.6GHz at 139MHz frequency, that means the multi is 11.5x, so it's an 1800+. If you had the RAM set at 166MHz, that could be the reason why you couldn't go any higher. However, you MUST lock the PCI at 33MHz, AGP at 66MHz. If that's not possible, they will overclock along with the CPU. Take it too far & you risk corrupting the data on your hard drive, having problems iwth the sound, video, or anything else that runs on the PCI/AGP bus.

We need the make/model of the board.

As far as I know, it's a VIA EPIA M9000, with Pheonix Award BIOS 6.00PG. I've got the 1800+, that I'm sure of. Thanks for the help so far. Remember, I'm a noob at OCing.

"it's a VIA EPIA M9000"

Are you sure about that? That's one of those tiny ITX boards with a non-removable CPU.

I guess if I had looked a little harder, I would have seen the entire chip. Sorry about the guess, but I'm sure that it's a VIA VT8235 Southbridge, same BIOS, etc.

That still doesn't help. The VIA VT8235 Southbridge chip is used on dozens of different boards. You need to find the actual board model number. It should be printed on the board somewhere. Or you *may* be able to get the model number off the screen when you 1st boot up, it's usually part of the BIOS ID string.

CPU-Z will also (usually) tell you the board number as well. If you are OC'ing you will need it anyway as well as SpeedFan.

You have to be a little bit crazy to keep you from going insane.

THanks for the reply. The BIOS screen displayed KM400-8235-6A6LYE1BC-00, which I took to mean an ECS motherboard (plese correct me if I'm wrong). I got apic of it, too, and it seems to match my motherboard exactly (except for the color of a few things)>

second one down, the red one.

EDIT: I do already have both of those programs, and am learning how to use them.

KM400-8235-6A6LYE1BC-00

The BIOS string seems to point to an ACER ECS Board, they are not the same as an ECS Board, is the PC an ACER ??

It's either an Abit VA-20 or the Acer version of the ECS KM400-M2. If you have an Acer PC, that should have been mentioned 10 responses ago. Here's the Abit board:

A far as I can tell, I've got the Abit mobo. I don't have an Acer computer. I actually have a DIT. IDK if they were ever partnered with Acer, but that's what I have. Thanks in advance for any help you can provide.

The model number is circled in the picture, did you check your board?

Yes, I checked (sorry for the late reply, I've been busy). It's the ECS version. Sorry, I was in a hurry that morning, and didn't have very long to check. I'm sure I've got the ECS motherboard.

I have not run AMD's so I will leave any detailed comments to others.
