should I unlock my XP1800?
- Thread starter snidy
- Start date
If you want to!!
For example - theres no point unlocking the CPU if you are not going to actually change the multiplier and overclock it.
To properly answer you you need to give us some more details - what do you intend to accomplish?
Are you just curious as to what it can do? If so, then the article that Torghn linked to will do that for you.

I am sure thats what he is planning...I am considering buying an Athlon XP chip and I too am curios in the o/c capability

free megahertz! have the fastest cpu on the block! thumb my nose at Intel!

so others have done this w/o any problems and are there any other ways to accomplish this?
thx
My goal is to overclock to 1700 mghz, do you think it's safe? My system has a lot of ventalation, I usually run 34 idle and 40 full load.
dugr.. Yes I realise the general meaning of his question, however to give him some useful information I needed a post like the one above this.
OK snidy here we go!
1700 MHz is your aim and stock is 1530 right?
Considering I can overclock my 1700+ to 1595 speeds and have Windows boot (it is stable for 30 mins.. about) I am sure it is possible. I am using the Zalman flower cooler at the moment - this is known for its lack of noise, and not its cooling performance. Providing you get a really good CPU cooler, like the Alpha Pal 8045, and you have enough airflow throughout the case, I am sure it can be done.
Of course a succesful overclock depends on a number of factors. Plan your overclock - How are you going to go about overclocking? FSB? Multiplier? Both? (obviously you intend to use the multiplier, but you can FSB overclock too to get a cool result.
Here are some options: Bear with me here!
Multplier only
11.5 x 133 = 1530 (stock speed)
12.0 x 133 = 1596 (just about 1900+ speeds)
12.5 x 133 = 1662 (almost there)
13.0 x 133 = 1729 (goal achived) (however a lower multiplier and higher FSB would be more stable I believe, so on to the FSB!)
FSB only - you can do this method without unlocking your Athlon XP. This is now stressing your entire system, as that is what you are overclocking, not just your CPU. RAM and motherboard must be up to it.
11.5 x 133 = 1530 (stock speed)
11.5 x 140 = 1610 (more than 1900+ speeds) - This should be possible off the bat, as you can overclock straight to 140 FSB almost without fail.
11.5 x 145 = 1667 (nearly there) - This will really be putting your system to the test. At this speed FSB, my graphics card causes the system to crash (Radeon 7500)
11.5 x 148 = 1702 (goal achieved) - I would be surprised if you achieve this overclock - but its not impossible. A combination of the two is needed =
A Combination
11.5 x 133 = 1530
12.0 x 133 = 1596
12.0 x 140 = 1680 (goal nearly achieved without pushing CPU or FSB to their limits...) To get more, you need to increase either the multiplier or FSB, which you do is up to you.)
12.5 x 140 = 1750 (Wow... this is overkill - therefore back off that FSB ->)
12.5 x 136 = 1700 (that would do it) (OR ->)
12.0 x 142 = 1704 (there...)
As you can see, there are many options. Your best bet is to find the combination that stresses your FSB and CPU the least. The ideal combo will be different for your hardware.
1) If you have a very OC friendly CPU yet your graphics card (or similar) doesnt like high FSBs, then the 12.5 x 136 is perfect. 136 is hardly an overclock of the FSB afterall.
2) If your situation is the other way around, then go with the 12.0 x 142 option. Since some people are able to get FSBs to run stably at 150, then I am sure that 142 is possible.
REMEMBER FSB and multiplier are only the components of the resulting CPU frequency. It may be necessary to raise voltage of the CPU amongst other things to get it to run an overclock as high as this (although my experience is limited - just dont increase voltages steeply, a little at a time!)
Hope that helps
Edit:
As I said above, I have only talked about how to do this overclock. You may need to raise volatages. You will also need to ensure adequate cooling. Bear in mind that this will not be a very quiet or cool system. An intake and an exhaust fan is, I believe, the bare minimum required for a mild overclock, let alone a serious one like this.
A very good Heatsink-Fan is in order, try the Alpha PAL 8045 or the Thermalright SK-6 - they are top components.
Extra case ventilation is always a good idea. A blowhole at the top of the case aids tremendously as hot air rises...
Oh, and use Arctic Silver. Please

I have a question for you guys! I unlock my xp1900+ with a kit(I think it's successful unlock).. with the epox 8kha+. but in the bios I don't have 12.5 multiplier there! these are the available multiplier - 11,11.5,12,13,14,15 ! how do you select 12.5? or my unlocking failed??
Nice, Migroo, but you forgot that 133 is actually 133.33 MHz. 12x133 = 1600. Exactly. That's exactly what the 1900+ is. 12.5x133 = 2000+. etc.... Once you change the FSB, though...at least on my mobo, you can't get back tot he 133.33...just 133, in which case you'd be stuck at the 1596.
hehe o/cin the fsb rocks! got my xp1900 upto 1780 - started to get a touch hot on the old aplha 8045.
fsb aint a prob with me though i've benchmarked my sys @ 164 mhz.

13 is actually 12.5 - well thats what tomshardware say anyway. i got my xp1900 stuck on x11 after a failed unlock attempt. cleared the bridges and it works fine now
what do u guys think is the best unlockin solution? the conductive pen or the silver lacquer?

I also have a Dragon + and have heard the complaints about lack of overclocking. I have a 1800XP (locked) at 153 MHz FSB for a grand total of 1.76 GHz. This thing is rock stable, i had to choose +.1 on the cpu voltage though, but my temps stay at 35C with my AlphaPAL8045. I dont know about you, but having this motherboard and not using any PCI slots is awesome, it for sure helps the FSB overclock. So I think, you should be able to hit 1.7Ghz easily with your board and CPU.....it wasnt worth the risk for me to try to unlock this thing.
<< Would it be worth it? >>
Realistically not. Overclocking some 66MHz or 133MHz does jack in real life short of FPS counter and benckmark.
<< Is it safe? >>
Overclocking is risk taking process. CPU is like an expensive lab glassware. You fry it, chip the core and its the end of it. You pay for the damage. Not your retailer or AMD or your friend.
Another thing to have in mind is when you blow an XP1800 and re-purchase, the sum of the two is enough to buy you stock XP2000+
<< and what's the best way to do it? >>
Whatever you feel comfortable with. Only thing you can't do without is steady hands.
Just put a XP1800+ in EPoX 8KHA+ motherboard (Thanks newegg!). Using GC68 Aluminum Heatsink which is a nice unit that fits well on the board. Arctic Alumina heat sink compound (not sure if that matters - maybe I should have used AS2). Booted up stock and get 34Cto 35C under load.
Didn't want to fuss with unlocking just yet so simply selected 150fsb with no other changes - locked going into Windows98 No big surprise. Dropped it down to 145fsb. Booted fine, 3DMark2000 fine, Sandra fine, Quake fine. Temps maybe 1C higher.
Reports like an XP2000+. My PCI components have been in higher PCI bus overclocks in the past on BX boards (from 100 to 140) so I don't expect any problems. I'll try smaller increments up to 150 fsb to see where the limit is with stock voltages. Then I'll try raising the voltage after doing some AMD XP research.
Migroo - I appreciated your thorough explanation of the various fsb/multipliers.

My 1800+ goes to 1710mhz/148fsb 1.95v 100% stable.... AGKGA core, i'm happy
I did unlock it at one time but the motherboard didn't really understand what I did so my multipliers wouldn't go above stock but they would go below

Sounds good Lark888. Those are some pretty impressive temps youre getting - if those are what you regularly get, then dont worry about using AS2, unless you want an excuse to open your PC up
About the 150 FSB - its probably just one component that is limiting the FSB, as it becomes unstable - this could be anything from CPU, RAM or a PCI card. Have you got decent RAM or is it generic? - if you have 2 RAM sticks, try running with just one, and upping the voltage slightly. Same goes with the CPU.
There are quite a few people here who have managed the 150 FSB, (I'm not one of them - yet...) so perhaps they'll help out
Oh, and youre welcome

hehe i just got my corsair xms2700 ddram today. default spd of 166mhz. had to take my xp out of the board cos it won't boot @ the speed ie 12x166 hmmmmmmmmm. put my old tbird 1.4 in dropped the multi and away i got. benchmarks here i come
