Athlon XP 1600+ (1.4GHz) ----> Duron 1.8GHz

I would do a pin mod or a vcore mod, whichever is easyer. I was unable to find a web page with a voltage mod on it, but I found several pin mod pages. One thing I was concerned about is that not all of the pin mods I've seen are on the same pins. This one looks the most reputable, but it doesn't actually say that if it's changing the VID or the SVID or what. I don't want to do a mod that is untested. I think I have to change the VID to up the voltage? Also do I have to cut the pins off or cut the traces on the board to the pins if I do a pin mod?

There should be modified K7S5A bios's out there that allow some overclocking. I found some when I was curious a while back fiddling with the one I had. Do you think perhaps your limited overclock is because there is no PCI/AGP lock on that board? Is there a way to run a PCI/AGP divider so you can ramp up your FSB further?

I swaped the K7S5A for a KT600-A so I could run my new DDR400 memory at 200MHz. A friend had the board sitting on his shelf and he just gave it to me. It seems like a much better board than the K7S5A, so I'm going to keep using it.

It probably is a better board. lol. Free stuff is always good.

It also helped that your ram's running at CL=2

look up wire mods on the Socket A, you can artificially raise the Vcore using U-shaped wire in the socket 🙂

1800 = 13.5 x 133

13.5 x 166 = 2250 🙂

According to the AMD datasheet, it looks like I need to connect pins L5 and K6 together to get the voltage up.

Pin mods. Plenty of pin mod in that link.

Update:

I soldered the pins on the back of the mobo socket, and now it runs at 1.7V. I set it to 166FSB and it will pass 24hrs memtest86, but it bluescreens on windows boot. I then tried changing the multiplier, but soldering the new multiplier on the back of the socket did nothing. (Yes I checked and all the L1 bridges are closed on top of the chip.) So now it's running at 150MHz FSB/150DDR mem with 2-2-2-6-1T timings. I get 217fps in quake 3 fastest Demo001, 60seconds for superPi 1million, and 4min53sec for superpi 4million.

It most likely does not have a locked AGP/PCI bus, leading to instability when accessing the HDD. If you manage to increase the multi, you might manage to clock higher, but thats the only way.

You're right about it not having a PCI lock. That's why I was shooting for 166fsb. I wanted to run my busses in spec. I don't think I can change the multiplier though since I have a "superlocked" chip. Even though the L1 bridges are closed, changing the multiplier has no effect. I'm currious if I could mod the cpu into a mobile and try to change the multiplier with powernow.

Seems you did OK. For $217 though for gaming I would have gotten 6600GT as a single upgrade. Maybe you should have spent a big more and gotten 3000+ and A64 board. Oh well, your next upgrade should be a whole new system though.

 

[Brian23]

I'd love to have a 6600GT, but I do more programming, video capture and editing, internet browsing and general multitasking than I do gaming. My next upgrade is going to be a video card though. 🙂
