View Full Version : Overclocking problem with a 1.4 Athlon
Ok perhaps I'm missing something here.
My processor came unlocked, but any attempt to push it above 1.4 ends up locking windows at the EXACT same point on every boot. It's really weird I went to the "system config utility" and turned off EVERYTHING under "startup" thinking something was locking the system and it still locks while loading. (The hourglass is on the cursor) I can't figure out exactly what the problem is. Whatever it is it manifests itself at ANYTHING over 1400. It will boot and lock at this point at any clock speed from 1426 -> 1550. (I didn't try lower then 1426, but I'm sure it would lock) Any guesses guys??? I've tried every voltage from 1.7 to 1.85. :( Quite depressing.
Things I've tried:
Changing voltage 1.7 to 1.85 and everything in between.
Disabled everything in "system config utility"
Multiple clock speeds from 1426 to 1550 all boot and lock in the same place.
Disabled ACPI in the bios. (No effect)
Multiple memory settings. (Everything from the least to the most aggressive)
Setting bios to fail safe.
Needless to say it's now almost 4 am and I've exhausted every possible thing short of re-installing. If anyone has any clue please let me know. (Huh my friend passed out about a half hour ago... hehehe)
Some Specs:
230Watt Power Supply (I know, I know, but it works 100% for weeks w/out lockups. Seems to be fine at 1.4)
NEC PC100 Ram (Works 100% at up to 140mhz. Tried pc133 still locks.)
Abit KT7a-Raid
2 IBM Deskstar 30GB
Sound blaster Live
Radeon 64mb vivo
pci 10/100 network card
isa 10 network card
thermoengine w/7000rpm fan. (~40c w/load)
I just got two 1333 AHYJA chips and they both do the exact same thing. Great boot and as soon as the start up programs run it locks. I posted the problem today. I also tried all voltages. If you have good ram try this. Run about 1.8v and leave it at the default multiplier and raise your FSB. Its the only way I could get it overclocked. 151x10 at 48c. I know the cpu can run faster. I just cant use the multiplier and the ram is maxed. If you figure it out let me know.
you could try pull out all non neccessary cards i.e NIC, sound card etc and put only 1 stick of ram in it.
I don't think that will make a difference for myself. I just pulled my TB750@1104 to replace it with this 1333. Never had a single prob with my prior cpu.
costs nothing to try and remember you are now running different multiplier and FSB settings some cards may not like the new settings especially ISA cards
Some people have reported that setting the parameter k7_clk (or something like that) in the bios, from default to optimal helps that problem.

I don't know how to fix your problem, i'll think about that today, but you should really spend some money on a new power supply. That 230 will only bite you in the ass later. Also, ram is dirt cheap. Why don't you get some nicer memory. You'll see much better performance at 133 2-2-2 than you will at 133 3-3-3, or even 145 3-3-3. Trust me, latency is important.
Just my 2 cents.

My 1.4 locks up @ 1.4 if i change the multiplier.... I have to run a 10.0 mult. I can run over 1400 if I change my FSB... seems to only lock when windows loads if I change the Mult.
That's exactly what I said earlier. Theres something up with the frigin multiplier. I was thinking maybe AMD is reaching there limits on these chips. I mean you can only fit so much power into the same size chip. Maybe we should try and get a hold of someone at TomsHardware so they can work on it. Anything would help.

Well I too have an AYHJA, only its a 1.33. Nonetheless, its pretty much the same core as the 1.4. I've got mine running at 1550mhz stable, with no errors in Prime95 or lockups. It is however, very hot, so I'm not going to push it up till i get myself a new waterpump. At 1633, i can get into windows, but nothing seems stable. I get my new eheim 1048 pump and 431 enermax power supply next week, so I should have an update for you then. Just babystep it up though, thats what i've been doing to 1550.
Finally got it above 1.4 (huh only 1.44) I tried a friends cheap 133mhz ram. If I change the mult from 10.5 it freezes when windows starts. 1.44 is the max with this ram though. (And it will only take a normal setting on the ram. fast locks hard) Going to pick up some crucial ram this week and give that a try. Next step will be a better psu.
Theres a lot of people saying the same thing about the new steppings, at every board i go to.
And the fact that they are all using abit boards (notibly kt7-a) is staring them in the face.
I think that is your problem.

just order a 1.4 and reading everybody problems.I have a abit kt7a, ya they suck ,but i installed win98 without Acpi and all is well.1.2 @ 1350 142/9.5 .I can go 151 but gets unstable.i thank gdog is right about the abit kt7a is the problem. its might even be that 686b who knows.A buddy just got hes 1.4 friday he gets 1560 on the asus a7v kt133a .now here is the kicker it at 12.5 /120 fsb. the math dont add up.the thing boots up @ 1560 . when i get my 1.4 I'll find a way to make it work or i will get a new mb.
The picture of a 1.4 at Tom's Hardware showed cut L1 bridges. I know this sounds like an obvious thing, but have you checked the L1s?

Got this tip from ABit's own forum.
Download the latest unofficial bios from Paul's unofficial KT7 FAQ (http://www.viahardware.com/faq/kt7/kt7faq.htm). Then you will get an option to disable the ACPI from the bios.
I did this and now I can run higher multipliers without a problem. It's currently stable at 1466, haven't tried anything higher yet, but I had to up the voltage. Now I just need better cooling :)
Parad0x: Going to try the new bios.
Colin: They are all bridged.
Cowboy93k: Yes I noticed this too. Seems 12.5 is really 13x multiplier. On my KT7a-Raid it says 12.5-17x for some reason it uses 13x.
New bios makes no difference. I also have ACPI disabled. No change. :(
Here are the chips markings for anyone interested:

Did you disable ACPI just in Windows, or under the Power Management section in the bios too?
I disabled it in both, and it worked fine for me after that.

Latest Bios Version I see at that link is 3C..
ZT1.11+ (http://www.viahardware.com/faq/kt7/faqdownloads.html)
U should also try to Overclock it and then reinstall Windows with it overclocked. Windows has problems with the overclocking thing. Then it should work. (ex:1.4@1.5 then format HDD and install windows) This could be the problem, especially if you are running win2k or winME.

How do you turn it off in windows?

How do you turn it off in windows?
I don't know how you turn it off in Win9x, but I guess it's pretty much the same as in Win2000...
Under the Device Manager -> Computer. Change it from ACPI to Standard PC, using update-driver. Then you've gotta reboot, and windows will re-detected all your devices.
I didn't think it was that easy in windows 2000. when adn if you re-install hit F6 and hold it then hit F7 and that should do it! if you miss it just try again!:)[/
I'm running 98. I can't find any place to shut it off though. I have it turned off in my bios. However according to my manual it's not "completely" off when switched off in the bios. It just turns off "some" of the acpi features. Any idea WHY acpi doesn't work correctly when clocked above 1.4? Seems to me it should work. And if it isn't the overclock isn't really all the successful is it?

Just get a new P/S! 300WATTs is the MIN!! ANd that was just for the 1200 that they said that for.. So what would you think will happen once ya go and throw in a 1400?
I would only buy a 400-450 WATT enermax!
KK
P.S. i only have a 300WATT and its only stable up to 1380... I had it at 1425 before but only with a 600 WATT P/S....I hooked 2 P/Ss together...
YA NEED MORE JUICE FOR HER!

Agreed Azz a 230 watt psu is absolutely not powerful enough for 1.4G Tbird. Have you checked the vcore at stock speed?
1
Try bigger psu
2
Try bigger psu
3
Try bigger psu
Hope it will fix the problem.
Wouldn't a bad (or not enough juice) psu give you intermittent problems? My lockup occurs at ANYTHING above 1.4 at EXACTLY the same point after windows starts. (At default voltage) And runs 100% stable for days at 1.4. So this doesn't point to a psu in my opinion. (However I do agree that I should upgrade the psu)

I agree that this psu is big enough @1400 if the cpu runs fine at 1400, but at what exact speed will this psu not be big enough? 1450? 1666? 5Gigs?
Lets put is this way, AMD's seem to be able to run at low core voltage at stock speed. I think this is what you are experiencing. You might be ecxatly on your psu limits. There is only one way to find out.
BTW how are your cpu voltages at stock speed? What does motherboard monitor, sandra or whatever program you use say about vcore? Is it the same value as you set it to in Bios? What happens if you up the voltage in bios at stock speed? Does it actually go up..check this out!! Test this under load also, see how your core voltage behaves.
I have tried to overclock Tbird with 235W psu, just didnt work to good. And at high speeds the core voltage vent down under load...remember that when booting your cpu is quite busy, and at this point is always locks up, it might need max jucie..
Good luck

Here's the deal. If I change the multiplier and clock it ~1400 it locks. I think there is something preventing the minupulation of the multiplier. But it only surfaces once windows starts. I've been overclocking for years and have never seen anything like this. It looks like it could be power management or some driver that's causing it. I've tried booting with no hardware other then a video card and it still locks at the same point. We're not talking while it's loading this is after the windows login, after the startup sound, and a few seconds after everything seems fine. The pointer shows the hourglass (something is loading) and then freezes. It's got to be some driver. It's almost as if windows is asking the processor if it's overclocked and then locks. [sic] Anyway, overclocking the FSB seems to be working to 1440mhz anything beyond and my ram craps out. (So this discounts a possible psu problem) BTW, I am ordering a new case with a 450watt psu. (Just to shut you guys up :) ) heheh
yeh i agree it looks like some new lock amd has putted in theyr chips. Since most of the ppl have EXACTLY the same problem even when they got 400w+ psu and good ram and things like that. Or it might be a problem of the abit kt7a board or??? Since most of the ppl who have the same problem got an abit kt7a mobo.......
If someone has sucsessfully oc an 1.4(ahyja) with adjusting multipilere plz post it here.
Its just so VERY odd. I just hope im wrong that amd has used a new method to lock theyr new chips..........

I don't have a Athlon 1.4Ghz, but I do have a new 1.33 AJHYA chip, and I have no problem with the multipliers. Right now I'm running stable under load at 1.466 with Glaciator at default voltage with no problem whatsoever. It may be a problem with the ABIT board....
It's amazing how quick some of you guys are at blaming the cpu for this overclocking or locking at normal cpu speed. Maybe some of you knew it all alone and don't want to acknowledge the fact that you're still using the Abit Kt7... manufactured for top speed of 1.2 Ghz. It's almost amazing anyone can get a 1.3 Thunder B. to work in that board. That board, when it works well, will overclock at 1.4 to hardly 1.5 Ghz, with lots of unstability problems, so consider yourself lucky if that board even boot. If you don't believe all this crapp I just spit, take a look for yourself
in the Abit.com motherboard Forums for Abit boards and you'll say deja vu. Once again check out the specs. on the board. Look in your book for that. AMD 1.4 is a new cpu and boards were not made for them then. Look for the new DDR boards out there, maybe ASUS7M. Look at the board.
It's me again.
By the way, did any of you notice that you're using the same Abit board ? Go to the Abit.com Forum and you will understand. Deja vu.

What are you talking about? I went to the abit.com forums and there isn't even one mention of a 1.4. Overclocking isn't even mentioned anywhere in those forums. If you have a url you could show me great. Otherwise if you don't have anything helpful to say, please don't bother.
FYI: I just got a 1.4 AHYJA with an Asus A7M266, Crucial DDR2100, SwifttechMC462 heatsink with Delta fan, and an Enermax 451W Pwr supply. Unfortunatly the 1.4 is clocklocked. In fact I tripped when the Asus bios showed it in boot up as a 1.333. CPUID shows it as a 1.4. Hmm? Anyway after a fresh install of WindowsME I went to 140mhz FSB and it was stable. Ran 3DMark2001 several times with no freezes. I then tried 150mhz and nothing. I went down 1mhz at a time from there and 140mhz is the only stable setting. My temps with Asus's CPU Probe is 41C max. That part is jammin'. Looks like the only way to further clock this baby is by bridging the L1's.

You know the 1.4 runs at 10.5 right? Anyway, my L1's look bridged. Are you sure yours is locked?
ok. Got it to work. I flashed with the latest ZT1.11+ bios and I'm running 1.57Ghz STABLE at 1.80v. !!! Can't wait to try pushing it harder. Should be able to get 1.6 pretty easy. I AM going to get a better psu and have some crucial ram already on the way. Thanks guys...
BTW, my problem was when flashing I used the supplied runme.bat and changed it to use the ZT1.11+ bios. Well this didn't update the bios and hence no change. Flashing with only the /cc example: awdflash bios.awd /cc worked and booting into safe mode removing all drivers, rebooting and redetecting fixed everything. Oh I did need to turn ACPI off in the bios to get it stable.

I haven't seen any mentions of this particular problem myself at the Abit site, I simply wanted to point out the fact that there is a limit on the board for cpu speed and that limit should be taken into account before anyone claims that the chip itself is the problem. I don't believe AMD would pull something like that. The chip is not clocklocked either. We just can't expect the same old mobo to do new tricks all the time. A new DDR mobo which supports fsb 266 mhz would make anyone very happy using this 1.4 ghz powerfull AMD cpu..
