Overclocking a Mobile Duron 1500+

[muhon_zen]

Hello, folks, I have a question.

My mom has this old compy. It's a PCChips M810DLU with a AMD Mobile Duron 1500+ onboard. Sadly, the CPU cannot be removed, so we have to work with this one. The bios doesn't have an option to modify the FSB or multi.

Current Specs:

CPUID:
CPU Type                  Mobile AMD Duron 4, 850 MHz (8.5 x 100)
CPU Alias                  Morgan
CPU Stepping           A0
Instruction Set         x86, MMX, 3DNow!, SSE
L1 Code Cache        64 KB
L1 Data Cache         64 KB
L2 Cache                 64 KB  (On-Die, Full-Speed)
 
 
CPU Speed 
CPU Clock                850.1 MHz
CPU Multiplier          8.5x
CPU FSB                  100.0 MHz  (original: 100 MHz)
Memory Bus            100.0 MHz
DRAM:FSB Ratio      1:1
 
RAM
DIMM1: SpecTek 512 MB PC2700 DDR SDRAM  (2.5-3-3-7 @ 166 MHz)  (2.0-2-2-5 @ 100 MHz)
 
DRAM speed : 100MHz (even if it's DDR266)
Timings: 2-2-2-5

I know the mobo sucks, but <i would like to overclock it at least to 133MHz FSB, so I could hit 1GHz CPU speed. She only uses it for email, googleing and word. But sometimes she likes doing that listening to music or watching videos. Sometimes she complains about the loading speed of the stuff, such as 5 or 6 internet explorer windows.

Any suggestions on possible overclock? Any software recommended that could allow me to raise FSB and/or multi? My cooling is great and I hit 33ºC on load, 29 on IDLE.

Clockgen is a pretty good tool for FSB overclocking, there is a guide and download here:

I don't know which pll her board has, so just experiment until you (hopefully) find one that works.

If you have trouble with software tools or want a more permanent OC then this might help:

I'm not sure how high an OC you are likely to get though, generally chipsets with integrated graphics don't overclock well. However I think the SIS740 might support 133Mhz FSB natively, but a Morgan might not be up to doing it.

Thanks for replying. What about if I get a PCI Video Card, so I won't rely on integrated video?

I think it is the fact that the extra logic is present in the chipset that is the limiting factor, rather than whether you are using it. If you can actually disable it in BIOS rather than just not using it it might help, but you aren't likely to get an astronomical OC anyway so I'd try as is.

It might also be worth trying a minimal nlited windows install.

It might also be worth trying a minimal nlited windows install.

Can you explain this to me please? I didn't quite understand the nlited windows install. Are you refering to use WinFLP?

No, sorry I should have been clearer. nlite is a tool for making custom cut down and tweaked versions of windows (2000, XP and 2003) to reduce memory footprint and improve performance. You can remove all kinds of useless files (such as drivers which you don't use) and unnecessary features (all the rubbish windows apps such as defrag, partition converter, etc). If you are thorough, it can result in a significant performance improvement.
