Duron 600 only overclocks to 650. Ideas?

I must admit I am new to this, this is the first time I have even installed a motherboard myself, so that may be the problem. I bought a KT7-Raid motherboard, Kong Fai case, Duron 600 CPU (OEM) and a CoolerMaster DP5-5G11 CPU fan. I built the system using everything else from my old K6-2 300 MhZ. computer, including 2 sticks of 32MB PC100 SDRAM. I connected the L1 bridges using a HB pencil.

Upon initial boot-up, I kept all parameters on the BIOS as defaults, and after installing all drivers, everything worked fine. I ran the computer for 2 hours (could the problem have been that I didn't burn it in long enough before fiddling?) and then checked PC Health on BIOS. It showed a temp of 28C for system and 33C for CPU (fan was active). I then increased the CPU voltage to 1.7 and tried increasing the multiplier to 9 (for 900 MhZ). System would not boot to Windows effectively (I got a Windows Protection Error), so I continued to decrease multiplier until it would, which happened at 7 (for 700 MhZ). I ran Sandra SiSoft to verify that the increased multiplier was working correctly and it was. Then I increased voltage to 1.85, and found that would allow me to boot up to 750 MhZ, unfortunately the CPU temp was up to 53C, though system temp was still only 29C. Unfortunately, that seemed to break something, because the system would no longer boot at 1.5volts (default) at a multiplier of 6, or at 1.7volts for a 7 multiplier, but it would boot at a multiplier of 6 with 1.6 volts.

Of course, everyone else seems to be overclocking at least to 850, some to 900 or 950. What am I doing wrong? And did I somehow mess up the processor with my overclocking attempts?

Thanks for any info you can give me.

More info --- now, best I can do now is 650 at 7.5 volts. It seems to be getting worse with time.

Can anybody detect anything I did wrong? There was something in the motherboard manual about connecting the power supply fan to the motherboard, but I didn't see any connections from the power supply that would apply.

How about the power supply itself. Is it a 300watt, 250watt, 200watt? It makes a difference when you hit the higher Mhz. Also the heatsink. I switched to an Alpha PAL6035 and dropped my temp alot over the stock heatsink. I have a 750 T-Bird and could get maybe 800-850 Mhz with stock HSF and now with the Alpha I can run SETI at 925Mhz and boot Windows at 980Mhz.

I'm going to back off a bit on my repencil comment....I reread the original post more carefully, and it looks like the computer does boot some at other speeds....

Mine would just get a black screen at other speeds until I got the pencil thing done right.

I am a little confused about the pencil trick.... I would figure my pencil should be fine since I am able to get different speeds, does it matter about how thick the line is?

Could it be that it is just a low-quality 600? Are other people having 600s that they aren't able to overclock but to 650 or 700?

I did check my temps with overclockers.com, seems that they are in line with what other people are getting at those voltages, but when I look at others they don't usually need to jack the voltages up so much to get to 650 or 700.

Thanks for everybody's input! I might try the pencil thing again next time I go in... But you don't think it has anything to do with not doing a 24 hour burn-in, right?

That Coolermaster HSF is a piece of garbage for overclocking. I'm replacing mine because the chip gets too hot when overclocking past 800 MHz.

The pencil trick isn't the problem. I've redone mine 3 times and I still can't make it to 900 MHz without a crash. It's the Duron chip; some aren't as good as others. That's why you see some people getting to 1 GHz with it while others only make it to 850 MHz or so.

yaknow...

if you are saying that you are using 64mb of ram from an old K6 system, that could be a major problem.

In any situation with overclocking, Ram is a real important thing to factor in.

I would really think about getting some new ram for two reasons.

#1 - PC133 ram will make a nice speed increase since the AMD chips support that speed.

#2 - Running any newer application or game on a system with 64mb of ram is simply crazy. You could go ahead and get yourself a P3850 and it would be simply crawling through an application like Photoshop 5.5 ...

A Duron 600 with 256MB of ram would be so much better than a duron 850 with 64MB!!!!

thats what I used to think, try rendering some serious 3d or video with 64mb ,,, Then you will know what sluggish is...

Look, Speed to access an instruction is just like racing a lamborghini on a city street with a ton of red lights. Sure, you will beat everyone off the line, but your computer will constantly have to stop and reuse the ram as memory and then build virtual memory on your hard drive. To top it off, it looks like you are running a ata33 drive!?!?! now, I am not necessarily a big believer in the ATA100s but there is DEFINATELY a difference between the ata33's and the 66's!

You have that 1GHz oc'd chip so bottlenecked with that ram, hard drive, and rediculous TNT card, I dont even want to start...

Here are my specs:

Duron 600@800
Mushkin 1.5 PC133 256MB
Geforce DDR
IBM GXP 20G ATA66 7200

I guaruntee that you would see some serious speed differences between our systems...

The ata66 drives are dirt cheap, and for about 130 you could step up to some Mushkin ram, then throw in a Voodoo 3 3000 and I promise you will say: "How did I ever live with 64MB of ram!!:p

I have a problem overclocking my Duron 600 to 650. I got it to do 850, but it wouldn't run stable. Then my comp doesnt start up for a while and I have to wait. I have a Global Win FOP38 HSF. I think something is wrong with my motherboard. I have the A7V. I wanna try overclocking on a KT7 because you dont need to mess with jumpers.

Ryan,

Did you do the pencil trick? If so, this might be of interest to you...

On my first attempt to overclock my duron, I used the pencil trick. I could get nothing past 650. So I figured I was out of luck. Then I redid the pencil trick, loaded the bios with defaults. BOOTED FIRST AT 600, Then I shot for 800 and wham! it worked. I think that the 600's can overclock to 650 with either no bridges connected or with the bridges connected very poorly.

In any case, I would try it again. Shoot, what do you have to loose! I saw that the prices for the 600s are down to 45 dollars!

I'd be disappointed with a duron that runs less than 900 though. A celeron 950 rig would have cost less and performed equally. So you may want to return that processor.

Ryan,
Is the A7V in JumperFree mode? If it is, try switching to JumperMode. Yeah, I know you hate jumpers, but the A7V seems to like the jumpers and DIPs a bit better. For some reason mine wouldn't boot at 600@1.85 in jumperfree, though it would work at 800@1.85, which doens't make any darn sense. Right now I have it running stable at 850.

One more thing to consider, my Duron would not post at any multiplier between 7.0 and 8.5, after being bummed out for a few hours, I tried 9.0, and what do you know? It performs flawlessly there?!! I have no idea why- I tried just about every voltage and bus setting at 7 to no avail but it boots at 1.7 @900. Give it a try, but keep your eyes on the temp while you do.

yes, please watch your temps!

sheesh 900mhz is cooking hot! I went from 33 - 39C at 800 to 51c at 900mhz 1.75v (yikes)

I am pretty happy with 800 though.

oh, and I would seriously doubt that the celerons perform at the same level as the Duron at the same clock speed. My roommate has a cele566 clocked at somewhere around 900 and my duron at 800 beats him on almost every bench. Course, the ram and video card makes mine a little faster all around also.
