How high do think this chip will go?

[xbassman]

I've been cooling modding my wifes computer case it's a pretty cheap one!
I figured while I'm at it I might as well see if I can find the max stable overclock for it without creating heat issues.

here's the numbers from the chip:
AXDA1800DLT3C
JIUHB 0320WPMW

It's been running about a year at default 2500+ speed (11x166) @ 1.5v
I didn't even try another setting Just booted it up installed windows and went. (ran prime for 24hrs)
So I'm sure it can do more.
Some limitations are: PC2700 ram, Aero 7+ HSF
Heck the heatsink was so bad I wore out 2 sheets of 600grit to get it smooth. Stopped @ 1000grit (wife wants it back soon )

I was hoping some of you guys might give me a leg up so I plop this puppy back on her deck pretty quick.

Thanks

its possible to make 3200 speeds but you never know till you try

 

[xbassman]

3200+ ?

I don't think the ram would do 11x200....
I don't think it's multiplier locked though.
Been about a year since I did anything with it.

I have another one in my daughter's PC that's on the block next.

11x200 is not 3200+ speeds for that cpu/core. 2.3-2.4ghz on that will make the system run an equivalent of about 2800+. 2.2ghz is only xp3200+ with teh barton core. 2.2ghz for clawhammer/newcastle is 3000+ or 3200+. dont forget that the athlon 64 2800+ at 1.8ghz is faster then the xp3200+ at 2.2ghz.

The extra cache on a Barton is definately PR overrated. If you can get to 2300MHz on any Athlon XP with 256k L2 on a 200MHz fsb, the extra 100MHz will give you the same performance as a stock 3200+.


I haven't seen an 1800+ 1.5v "B" core that wouldn't hit at least 2100MHz with decent air cooling. 2.2-2.3GHz is more like the norm, maybe 2400MHz with some luck.

I know there are guys on this board that have overclocked the crap outa chips like this one.
The main thing I am looking for is some info on multipliers and such. Most of the overclocking info on these chips is pretty old and getting harder to find good info.
The mobo it is on is a Shuttle AN35N Ultra v1.1

Seems like I remember dapunisher really getting a smokin' clock with one of these.

If it is a newer 1800+ the multiplier will be locked. I think your motherboard has 1MHz increments for the fsb and possibly core voltage adjustments. If so, I small bump to 1.60v and a 174MHz fsb should be OK for your memory for an even 2000MHz.

The default mutliplier for an 1800+ is 11.5x, so if you've been running 11x like you said in the original post then you can indeed adjust the multiplier. If that's the case let 'er rip at 12.5x and a 168MHz fsb for 2100MHz, try between 1.70 and 1.75v. After you obtain the maximum stable cpu speed at a reasonable voltage running decent cpu load temps, you can play around with the fsb speed, more is better. Actually a higher fsb speed at the expense of a few cpu Mhz is still better.

Thanks for the reply Rogue.....
Actually I didn't even know what the stock settings were.
I bought two of these and booted both of them up @ 11x166 and never looked back.
I had a bunch of projects goin on at the time and wanted them done.

Isn't there an issue going above 12.5 miltiplier. Some sort of lock? (<13 or 13 and up)
At the settings it was running temps never topped 50C even with the fans undervolted and the heatsink with the crappiest surface I have ever seen.

 

[rogue1979]

Most motherboards require a mod to unlock 12.5x and above on a cpu that has below 12.5x by default.

Honestly 2200MHz or so is probably the max you will reach, so using 12.5x x 176 will work great. If I remember correctly your motherboard should reach 200MHz fsb speeds with an AGP/PCI lock.

So with a higher fsb speed you will be using a lower multiplier, provided the cpu is unlocked of course.

Fsb speed gives nForce a tremondous performance boost, I would push the memory as high as it can go if you can adjust the multipliers.

If you have lukewarm PC2700 and a locked cpu, you should still shoot for 11.5x 183 for 2100MHz, a very respectable speed.

hehe...

I figured this processor was a mad o'cer.
I just booted up @ 12.5x166. Gave it 1.6v for good measure.

Time to dig out prime and memtest.

I'm not sure about the ram. It is Corsair Value Select (2.5)
After about 10 minutes @ 100% load it's running 41C. That's with the fans cranked though.

This is totally insane though. Currently @ about a 50% OC. That's about what the old Celeron 300A's would do isn't it?

I am not sure what you mean here....
Right now I think I have found about the max my ram will do. It is @ 186mhz running memtest fine so far.
I tried 189 and 200 and the bios threw the comp into safe mode.
I know this board will run 200+ mhz bus speeds. Are you sugresting I run my ram asyncronous to my bus?

No, a 1/1 memory ratio is best for socket A, I just meant that your motherboard can push the capability of your ram to the maximum.

It's looking good so far, maybe try raising the core voltage to 1.70-175v and running 12 x 184 for 2200MHz.
Your temps are excellent, afterwards you might be able to tone down the fans and still keep good temps at the same overclock.

 

[xbassman]

Actually it's doing better than that.
12.5x 183 @ 1.675v Just ran prime for 2hrs 45min error free. I went ahead and stopped it for now to stop some more vibrations resonating in this cheap case.
I need to finish tying up wires and put the doors back on also.

I think I am gonna have to tweak this one a bit. My wife has all kinda crap installed and even at that speed it is as sluggish as hell

 

[Tiamat]

I have a DLT3C 1800+ and the max I can get is 2250mhz. I keep it at 200x11 now tho. Im feeding it 1.75V however.

Between 2000mhz and 2200mhz, i had to go from 1.6V to 1.75V.

If you want a stable and cool processor, just should try this setup. 166x12 1.5v (2000mhz), I´ve managed to work at this configuration for a year date (24/7). In fact this proccesor is a great overclocker, I´ve even managed to take it to 2460mhz (246x10, and even higher fsb with lower multpliers (263x9), with air cooling.
