Oc 1800xp

[Pendragon]

Hi Peeps,
My OC days are long gone, back with K6II and K6II+ and 600MHz was the goal...

What is possible with an 1800XP and how do-able is it?

I know about heat from the old days but what can be done?

those chips overclock very well, the TB2 core or barton core can hit 2.2-2.4 Ghz actual.

Just make sure you get a recent board that let's you change the multiplier without modification to the processor.

The motherboard is a cheap crap one. The BIOS settings are as follows:

CPU PnP SETUP

CPU SPEED 133/133MHz
CPU FREQUENCY 133MHz
DRAM FREQUENCY 133MHz

There are no settings for multiplyer and things are set to maximum... Dose the pencil trick work with this CPU? I don't want to anything much more than that...

I'm not sure which CPU I can upgrade too... I have become complacent about this type of stuff. I used to be realy gemmed up on the type of thing...

What board?

The board is K7SOM+ It's real cheap and nasty, on board shared graphics, with no AGP slot and only two PCI slots... both full. When I got the PC it was only to be used as a gateway for the rest of the network and for my wife to play Freecell... So cost was the major factor, now a year later much to my surprise I have bacome involved with online gaming. I'm hooked, MoH lib, I have joined a clan... well as you can imagin it has taken over my life some what! The least important computer in the house has become the most. I have upgraded the graphics with the fastet PCI card I could find, the ram has gone up to 512Mb.

I was hopping that I could squeeze a bit more out of the CPU or at least swap the chip for a faster one...

The absolute most important bit with an AXP 1800+ is which core it has. If its a Palomino, it wont overclock much, maybe 150mhz. If its a Thoroughbred-A, it might go 200-400 Mhz. If its a Thoroughbred-B, expect a 700-900 Mhz overclock. The next important bit is what front side bus your memory and northbridge can handle, not to mention at what point the buses are running too far out of spec as you push the front side bus up. First, identify that core though.

The K7SOM+ has the CPU down. It is an overclocked Duron. Nothing can be done to improve it.

Only ever heard of these with the o/b Duron 1200.
Soldered on as I remember.
Have you prised the duron off then??

I must admit that confused me when I Googled for info on my motherboard. The reason I have identified it as the + is from the MB handbook and the POST screen. K7SOM+
It has a normal soket fitted with an XP1800. A friend of mine has the same board from the same vendor but this time fitted with an XP2400. I'm geussing that the XP2400 is the fastest CPU I can fit. It would have been nice if I could have gone with one of the Barton ones... 2500 or faster... I now know I wont be able to OC the CPU with the motherboard I have. Unless I can phicaly alter the CPU PnP settings, The modern equivelent of the pencil trick. So the Motherboard sees the XP1800 as maybe a XP2400.
