Overclocking XP 1800+

[Herby]

Hey, I've recently bought a XP 1800+ with a soltek motherboard, i have aa dragon orb 3 cooler from thermaltake(7000rpm) and 256 MB DDR SDRAM. I would like to overclock my processor to 1.6 GH or more. Is there anyone who already has done something alike and how ? Any suggestions or tips are always welcome.
Grtz. Uncle_B

I have a xp 1900+ and I have sucessfully overclocked mine on a msi ktpro2 to 2100+ just using fsb.....or if you want to you can unlock the multiplier by the trick shown on toms webpage (read)...
ps...if you are new to overclocking cooling is a must.....of course water cooling is the best but is at the least extreme....a good heatsink fan is the swiftech mx462...or the silverado noise control or the taisol brands....a good thermal past such as artic silver II is also a must...you also want a good case (i prefer antec high performance cases (the antec sx840) they run around one hundred bucks and come with a four hundred watt power supply and have the capacity for five cooling fans) you can get these on princewatch.com
you want a good balance between raising the fsb and the multiplier so you will ahve to play with it to get the desired setting taht you want...good memory is also a must (i prefer high performance mushkin, or pc2400 from corsair)....heat spreaders may also be good =]

hope i helped you out but again just check up on toms review of unlocking an athlon xp

This guy is trying to overclock by 66 MHz and you're recommending a new case and new cooler!? With a Volcano and a decent 300W PSU (30 A on the 5V line), there should not be a problem. If you are running a fairly full case with a lot of drives and cards, then a new PSU is a good idea but apart from that a couple of decent case fans and you'll be laughing.

I could say something funny but, frankly, I can't be arsed.

the XP1800 runs at 1.53 GHz, each 66 MHz adds to 100 XP rating. 1.6 GHz means you are barely increasing by 66 MHz, thats just XP100! You can go much higher than that.

you have a good cooler and good board, check your power supply is at least 300W, if you have a burner, DVD, high-end graphics card and a lot of internal devices then consider getting a higher PS.

now, you XP1800+ runs at 133 MHz FSB with a multuiplier of 11.5, and you can overclock the processor by either increasing the multiplier <b>AND/OR</b> increaseing the FSB.

To change the multiplier you need to unlock it first, check tom's video that demonstrates this. then you can change the multiplier in the BIOS.

you board supports increasing FSB upto more than 166. 133->166 MHz (core speed will be 1900 MHz, approx XP2400!) in one go wont probably work. raise the FSB in steps of a 5 MHz or so and check the stability, if windows crashes or you experience anything unusual, in particular memory errors drop the memory timings to 3/3/3 in BIOS and try. if it still doesnt work, increase the CPU's core voltage a tad, the board will allow you to increase the core voltage in steps of 0.025V, till now you wont need to change the multiplier.

the speed this was you get is actually better than the standard XP rating, e.g. if you get 1.67 GHz running FSB of 145 MHz, its actually better than the real 1.67 MHz XP2000+ because it has better faster memory subsystem, I would like to call it as XP2000++!

one thig to keep in ming is that while you are increasing the FSB, watch the temperatures, dont let them go much over 50°C, and dont let the derived frequencies, the PCI (which is FSB/4) and AGP (FSB/2) go too high. rule of thumb, dont let PCI speeds go above 40~42 MHz, which is actually much within the range till 166 MHz!

hope it helps, keep posted.
