Duron 650 week 24 @ 945 w/ only chrome orb... can I do better?? (50C)

[Louse]

Hey... I'm on the A7V with my Duron 650 @ 1.85v with temps around 50C with the AC on and case open. Do you think that I could do any better with a better HSF? Take into account the week of my processor and all... And I need to get some case fans too... one for the front intake, and there is a slot in the back by the processor on my Antec Midtower, 90mm I think... What are the best fans I can get, and if i put some artic silver on there, how much would it take down the temp?

One more thing... how accurate do you think the Asus probe temp is on my A7V? That is what the temp was recorded with!! Thanks in advance!!

BTW, I am at 9.0 x 105 FSB... let me know if you need any more specs!!

I would guess that your chip is around its limit. No real way to be sure without dumping loads of money into it for extra cooling though.

Personally, I'd stick with it. I don't find it worth spending $50 on cooling to get and extra 50MHz on a chip that is already running at arounf 950. Of course it could go further...

hmm... if you're using a later a7v bios, and those are load temps(i assume they are), you're getting about the best performance you will out of a chrome orb.

You may want to try one of the taisol heatsinks, but you may also be near the limit of your chip(overclocking wise).

Even if you are at the limit, you may want a better HSF. 50C is towards the hot end of ok. Case cooling should help. Arctic silver gave me ~2C, worth it? I don't know. Some people have posted more impressive results, but I wonder how accurate they are.
A7V temps shown are off, but later bios'are supposed to compensate. I'm not sure if anyone really knows what their true CPU temp is. But accurate to within a few egrees is good enough. Not like your taking the temp of a sick baby or anything!

50C is not bad at all with a A7V at 1004C/D bios revision under load.

You've got a very old duron and thats probably all you are going to get !

 

[Mikewarrior2]

No One except amd has ever gotten a good temp reading of their cpu core temp. And unfortunately, there is no way around this.

The updated kt7/a7v bios' are within 2-4C of what core temp would be, but you still can't be sure what it is. And IMO, this is still not accurate enough.

And testing Artic Silver on a socket A system is a super tricky proposition. On Cpu's that measure core temp(ie p3's internal diode readings), the temp gains are remarkable. Compared to my melcor ALuminum NItrade grease, the temp difference is anywhere from 3-4C. The problem with trying to see the advantage with AS on a socket A system is that the thermistor based solution does not show the full range of cpu temp movement(ie, most of the time, the movement is 5C from idle to full load, when in actuality, the movement should be at least 10-12C between idle and full). So the results are compressed, and you could be gettiing a 4C advantage with AS and not be seeing it.

You might want to take a look at the article on overclocking that MikesHardware has just posted.
This is the best, most practical, single article that I have seen anywhere. Highly recommended!
He not only goes into the actual overclocking but also talks at length about the advantages to be gained from optimizing your BIOS.

I agree though that you are probably near the limits for your Duron, 900-950 is considered the max for the earlier weeks (I have week 27 650). So 945 is not shabby at all.

Your Antec takes 80mm fans, I have the KS282. Good sources to check out where they give some info about the fans is:

roedrunner, what's with this bios rev d? rev c is the latest shown on the asus website as of right now. thx

Louse-
Have you hit a FSB limit of 105MHz? Because I seem to be stuck at 105MHz and can't go any higher, which is strange because 105 is not that great. I've only attempted @ 8.5X but want to up the FSB.

 

[paulip88]

zeppelin,

Keep in mind that when you up the FSB on a KT13 system that is set up to use PC133 memory, upping the FSB has a dramatic effect on the speed of thememory bus. At 105FSB your PC133 RAM would be going at 140MHz.

However, if you are running PC100 memory settings, then you might be a bit more disappointed.

BTW, zeppelin rocks, as if you didn't know

paulip-
Thanks for your post. I'm running a A7V system. I've got Crucial 133 CAS2 RAM, which should be able to do 140. But I've tried it at 1:1 for the memory bus, and still can't boot into win98 @ 107 FSB. What's limiting me to only 105 FSB?

 

[paulip88]

zeppelin,

At a 107MHz FSB, your RAM would be running at 142.7MHz. There are two things that you should try.

1) Set your RAM to CAS3. Your memory may be able to do 133 CAS2, but it may not like 142.7 CAS2.

2) Another possibility is that there is some other component limiting your OC. Try setting your RAM to PC100. If it still doesn't work, then the issue lies somewhere else.

The KT133 simply isn't good for FSB OCing. The 105FSB actually isn't that bad, although some have been able to get it up farther.

 

[Mikewarrior2]

You ram should definately be able to handle 142(crucial cas2 has been known to hit 150+mhz at cas2 settings). Chances are, it is the kt133 chipset holding you back(almost every device can handle a 35.1 mhz pci bus).
