How to O/C Athlonxp 3000+?

nitrousoxide52

Read the title , any input would be great, if you need any system info just ask.

good start would be to up just up the Bus to 200 to run 1:1 with 400DDR, if yer RAM supports it of course, is it multipier locked? if so, you'll prolly need a lil more voltage, if not you can just bak down the multi a lil.

nitrousoxide52

I think the bus is stock at 200, and everything can be unlocked.

[hobo]eclipse

Depend wat yer lookin to do? lookin for over all MGHz or lookin for better bandwidth with yer FSB, it would be a good idea to lay out yer specs in yer sig or post em, just 4 a reference.

nitrousoxide52

clock speed 2100
FSB speed 200.0MHz
multiplier 10.5x

that's the cpu speeds, I'm not exactly sure what you are looking for, do you need volts too?
voltage=1.632

Zelig

Start by upping the fsb as high as you can keeping the ram in sync. Most likely, you'll hit the barrier quite soon with that ram.

After that, there's not much worth doing other than raising the multiplier until you reach your Mhz limit.

I recently overclocked a 2600+ t-bred which was one of the simplest overclocks I've ever done. It being a KT400A board, the apg/pci slots couldn't be locked, so only the multiplier could be changed. 14.5x wouldn't boot regardless of voltage, and 14x worked perfectly stable at default voltage. Took me about 5 minutes total, excluding stability testing.

nitrousoxide52

So, how much voltage for each x1?

FearTheTerp

Your current voltage is currently sufficient for some stable overclocking without raising it. You might want to raise it to 1.70 or 1.75 if you want to go higher than a multiplier higher than 11x. How high can your multiplier go?

nitrousoxide52

I think it can go as high as I want, I'm not sure lemme check, be right back.
edit//10.5 is the standard, I bumped it up to 11 like you said, and the multiplier goes up to 22

nitrousoxide52

Odd, when I check in cpu-z it lists the multiplier as 10.5, even though I bumped it up to 11, and that's what it says in the BIOS, I'll keep looking for more options that may help me with this

FearTheTerp

Yeah, a xp 3000 has a multi of 10.5. Did you save the settings before you exited the bios?

Geminiwave

also its probably fully locked. Seriously even if your MOBO insists that its changed, I'd wager that its locked.

Unless of course your clockspeed is showing higher, in which case CPU-Z is just full of itself.

which Geil ram do you have? Do you have the ones with the gold heat spreaders? or the blue.

I got the high end stuff(cost me an arm and a leg but its worth it) the PC3200 can push all the way up to 250mhz no prob, so you should have PLENTY of room. If you got the 2.5 CAS or 3.0 CAS, you might have trouble, but hey s'all good.

Crash Override

I always recommend raising clock speed by raising the FSB instead of the muliplier.

higher bandwidth for the memory as well as high CPU speeds.

Best of both worlds.

FearTheTerp

Geminiwave, are you saying I can hit a 250 FSB with a 1:1 divider with my corsair Xms 3200c2? 2 CAS?

nitrousoxide52

I have the geil with the blue heat spreaders[remember I have infineon sht too ]. When I raise the multiplier, it doesn't show in the bios under internal clock, it says 2100mhz, even though the multiplier is 200x11. There's probably some option there to unlock it, there are tons of options, and I'm scared to use some of em

FearTheTerp

Did you choose expert mode under CPU speed or something?? Don't do Aggressive or Auto or something like that. So you have Decent Geil pc 3200 and a piece of crap infineon?

If you have a kind of RAM like valueram, I doubt it could get much more than a 200 frenquency.

nitrousoxide52

I basicly just want to raise the multiplier on the cpu, the ram overclocking options are on optimal which is default.

Geminiwave

no thats not what I'm saying at all(although I've seen corsair ram go that far before)

I'm saying that Geil is good ram and I pushed my geil ram to 250mhz. I should clarify that it is NOT at CAS2. I got PC3200 RAM with CAS2 latencies, but by no means does it stay that way when you increase the speed by 25%. The thing is, that if you have RAM that starts out at CAS3, then you wont be able to push it a whole heck of alot.

As always, your milage may vary.

btw, in my experience, the CPU gives out before the RAM does. my RAM has always had much more headroom than my processors.

nitrousoxide52

My geil starts out at 2.5, so I won't be able to get that high.

nitrousoxide52

So, does anyone know why when I up the multiplier it doesn't actually change anything?

e v o

athlonxp's multipliers are locked. The mobile versions arent

Ben

nitrousoxide52

Ah, is there a way to unlock it? Or do I have to do fsb?

[666 w00t]

[hobo]eclipse

if its locked thats yer only option

nitrousoxide52

Found some websites on how to unlock it, but it has to do with connecting L1 connectors and stuff, and I'm scared to do it

FearTheTerp

You have to mess with the pins or something a bit. I would be too scared too. I would just raise the FSB as much as you can.

Why are the 3000 xp's multi locked and other xp's like my 2600 aren't. I can't move it up but I can move it down, is that considered locked?

Zelig

Partly. All the Athlon 64's are like that, while the FX's are unlocked either way.

nitrousoxide52

I'm thinking about doing it, I haven't read any stories about it going wrong, so maybe it isn't that hard, and isn't that easy to mess up.

Geminiwave

its hard. dont think for a second that its easy.

THG has the best guide(and a video to watch to see how hard it is)

follow that.

I'll see if I can dig it up on their site, but if I cant, you can PM me and I'll send you the video.

seriously though. its hard. You have no idea how tiny those contacts are.

Zelig

Heheh, I had the same thing when I modded my dfi ultra-d board to sli... it looked so big in the anandtech picture, and then when I took the heatsink off, I realized the wire I had prepared was way too thick and long.
