View Full Version : A question for the e"XP"erts....

I tried to unlock my 1800+ again this morning, again, with mixed results. Here's what I get after doing the L1's (superglue in the trenches, defogger paint over that connecting the dots). This is running on an MSI K7T266 Pro v1.0 motherboard.

This is what shows on the screen when booting (the numbers in parentheses are what it's actually running for a multi);

6x ....... No boot
6.5x .... No boot
7x ....... 933MHz (7x)
7.5x .... 1000MHz (7.5x)
8x ....... 933MHz (7x)
8.5x .... 1000MHz (7.5x)
9x ....... 1200MHz (9x)
9.5x .... 1267MHz (9.5x)
10x ..... 1200MHz (9x)
10.5x .. 1267MHz (9.5x)
11x ..... 1700+ (1467MHz) (11x)
11.5x .. 1800+ (1533MHz) (11.5x) (default)
12x ..... 1700+ (1467MHz) (11x)
12.5/13x .. 1800+ (1533MHz) (11.5x)
14x ..... 667MHz (5x)
15x ..... 733MHz (5.5x)

So, I have no even number multipliers available, and what would be even numbers get replaced by the odd multi's, one number lower. I can live with 6x and 6.5x not working, but I was really hoping for 12x, or 10x/10.5x to work. :(

Now, my question is, does this sound more like there's one (or more) still open bridges in the L1's, or does this sound more like a motherboard issue?

IE; what would likely cause this, the chip, or the board?? :confused:

TIA!!

If you want my opinion(don't know much about the XP's) then I'd say it's the unlock causing the trouble. If it were me I'd retry the unlock once more and then if it doesn't work I'd look more closely at the mb.

I'm not an eXPert either, but I tend to agree that it's a chip thing. It's much more likely that you have a bad unlock than a bad mobo that just has the multiplier screwed up.

Of course the best test is to slap in another AMD chip and see what happens. But I seem to recall that your other rigs are Intel.

I haven't been following the XP unlocking saga lately, but I assume that superglue and defogger paint is one of the tried and true methods. I'd start by examining the unlock with a magnifier. Does the defogger make a good trace in each case? Are any of the links crossed? Does the superglue entirely coat each pit? (Any gaps might allow defogger to short something.) Does any of the superglue obscure a contact?

Additionally I have a vague recollection that some XPs required sanding to expose the contacts before unlocking. Don't quote me on that, it really is just a vague recollection. But it should be easy to chase down.

Failing having a spare AMD chip or board for testing purposes, I'd wager it's the unlock and that's how I'd proceed.

Best of Luck,

Hey I'm new here and stumbled across this sight, and saw you were having the same problems I was with my xp 1600+ with Msi k7 master all of my multipliers are off by one or they just take me below 1ghz. I did it the exact same way you did to. Except now my problem is that everything was working great and when I tried to overlclock higher i rebooted and went to the bios and now only two multipliers are listed. 13 and 14 are the only two listed and 13 reads 10.5 in wcpuid the default multiplier. I am begining to think this is mb related rather than cpu.

I have seen this as well. The contact under the actual "dot" needs to be exposed by lightly sanding the dots. I'm assuming you did your reading and have done this but that was my only addition. I agre w/ nihili and the above members that this is an unlock issue and not a bios/board issue.

Ugh..I can feel your pain. The fear of removing that heatsink yet again, to attempt another retrace of the the defogger paint. :) Good luck, keep us posted.

...time for some leftovers!!

No expert here either, did you clean the contacts either with a eraser or x-acto knife before you stared?

Mr B.: I unlocked mine and all the multi's seem good, but the highest I can use is 12- after that I post and lock up. I LIGHTLY cleaned the bridges when I did the unlock.

My chip gets a better oc at stock mult. and 150 fsb than using the multipliers, the funny thing to me is that at ANYTHING but stock multi I can't adjust fsb or the os will barely load before crashing.

Even at stock mult. I can only go with a low fsb or 150! About 2 steps up from 133, or all the way to 150! Kind of weird, especially since it is rock steady at 150. I don't understand it, but I've given up.......for now!

Tom's hardware guide's review on unlocking the xp has a nice table showing what each bridge does and should tell u which bridge is giving trouble.

Welcome to the Forums! I looked up your mb and it says that it only supports XP's up to 1.4ghz. This MAY be what is giving you trouble. I read somewhere that some bios will read a chip to be a higher XP than it is if the chip is oc'd. If this is happening the bios might not like what you're doing. Have you flashed your bios and tried it again?

I did a quick stroll through amdmb and didn't see anythign that seemed related to this problem. As a point of information though, it seems that the multipliers that you are missing are precisely those that would require the bottom L3 bridge to be connected if you were controlling the multiplier via the L3 and L4 bridges rather than the BIOS.

I don't know what that means, but thought I'd share. :p

Ok...here's some answers to the replies...thanks for all the thoughts on this guys!

I went out and got a 10x jewelers loupe. I know the super glue is definitely filling the pits, and the defogger paint isn't contacting from bridge to bridge (crossed). I did, in fact sand down the contacts slightly with 1000 grit sandpaper. I suppose it's possible that one (or more) paint traces didn't take, but they looked good before I put the HSF on. I thought I had it this time...=(

Yeah, all the rest of my gear is intel. Good memory, nihili...lol.

This is what I've been thinking. The fact that another MSI user has experienced this phoenomina lends credence to my thought. I thought it odd that the multi's that work, and those that don't, follow a distinct pattern. I have flashed the BIOS to the latest (two weeks ago) version.....

Good luck, keep us posted.

Thanks! I will...=) No, not yet...I'm still full...lol =)

I've been watching your progress, as you and I have the same setup (and both got it at the same AMD show...lol) Get this; I booted up at a 133FSB/9.5x multi, and used the FuzzyLogic3 proggie to raise the FSB from within Windows. It didn't crash immediately until I reached 169 FSB (supposedly the mobo only goes to 164 in the BIOS). The Fuzzy Logic3 program goes higher. How far? I don't know, but I do know that I had it running long enough at 168FSB to check and see that there's no 1/5 PCI divisor that kicks in...=( I didn't try to change the FSB in the BIOS, only used the Fuzzy Logic3 porgram. Interesting results though....

(]-I got this board from AMD...this is the board they gave out with the XP chips at the AMD XP Tour. I would assume that it would support the 1800+ (1.533 GHz), if this was their choice to give away with them. I've had it run rock solid at 1.7GHz since I got it, at the default multi. Overclocking by multi only will "fool the motherboard" into thinking it's a different version XP. When I run 11x, it boots and says on the boot screen 1700+. 12x multi would show 1900+, etc....

I have flashed the BIOS...I'm gonna go and see if they've released any further updates later tonight....[/B]

[I]Closing the L3's (cutting is also involved here, to achieve certain numbers) permanantly changes the multi. It's still locked, but will default to a different multi (depending on what bridges are now open/closed). Closing all of the L1's completely unlocks all the multipliers.

Thanks for sharing...=)

==========================================

Thanks again, gang. Sounds like I'll be trying again...lol. I'm going to be doing a heatsink comparo shortly, so the HSF will be on/off/on/off/on/off... I'll keep plugging away...=)

lol actually i was talking to Extol but i did some research on yours too. Your mb should read all the new XP's fine. In my opinion i still think you should try once more b4 giving up on the board.

Oh, I intend on trying again. I also plan on getting another socket A board in the near future, to get a 2nd AMD rig Folding... =) Like I mentioned, the HSF is coming back off again soon...I'll have another go at it then.

Hey Mr. B when you sanded the cpu down to expose the copper contact did your cpu start peeling away around the bottom 5 dots. Mine did and now its really tough to see the dots it. The whole bottom row looks almost all copper now, but the good thing I got all the multipliers back finally and it's locked again. Reflashing the bios never helped so now I am stumped until I can get the contacts exposed right without removing any more of the cpu.
