well if this is anything to go by, i've had RC5 running for about 4 months straight on my c466, and the CPU temp in bios records 70 degrees c. I think something is wrong, I'm still running my stock HSF, although I'm considering upgrading to P3 in light of Intel's recent price cuts..

With RC5 running 24/7, and either stock AMD cooling or a FOP32-1 plus bay cooler and 80mm front case fan, my Athlon 900 ran at 50 to 53 degrees C at all times. If I removed the 80mm or bay cooler, the temperature wouldn't vary. If I removed the side panels, it varied slightly but not by much. I finally decided it had to be due to lack of airflow in the part of the case that the CPU sits in (my roommate's 900MHz Tbird runs at a steady 35C or so with no covers and nothing but the AMD cooling).

A few days ago I cut a hole in the side of the case and mounted a 92mm Sunon fan. Since then, the CPU temp hasn't gone above 45 degrees under full RC5 load, and it was averaging about 40, dropping as low as 35 if my room got cold.

When I woke up this morning it was at 45 degrees (the air in my room got a bit stuffy and warm). While reading this thread, I shut down RC5 and the CPU temp has stabilized at 31 degrees C. If my room were to cool down again like it was yesterday (wild temperature swings in here) then I'm sure the CPU could go down possibly as low as 25C.

Hehe, just noticed that my CPU is running at the same temp as the rest of the case. Woohoo! I've reached AMBIENT TEMPERATURE! (Well, ambient for the inside of the case anyway.)

Side blowholes rock. After mounting that I've been able to remove the bay cooler which kept pissing me off because it blew across my legs and was making a lot of noise without providing any cooling, and the front 80mm fan which again made a lot of noise but didn't pull in much air (the holes in cases for fans really are too small and too few in number to allow a fan to intake as much as it really can, and they cause it to make more noise while trying).

Damnit, still at 952...I was at 1GHz for about an hour then it konked out :(

Lord Evermore,

Too bad, if you could measure core temp, it would never match ambient case temp(with standard cooling ;)).

Well it's as close to true core temperature as I can measure without extra stuff. The thermistor is in the center of the socket of course, touching the bottom of the CPU package. The only way I could get it closer would be to have one between the core and the heatsink, or built into the core.

Since I shut down RC5 and opened a window near my desk, the temperatures have dropped to 27 degrees (both core and system temps were still the same).

MBM says that my CPU is running at 23C.
I'm running WinME, MSOE, MSIE, and several chat programs in the background. Could this be right?

When I access the BIOS on startup, it says that idling its about 50C.

If one's right, then the other one shouldn't be...

Whilst I'll agree that MBM v5.xx front end is a pain & I think that v4.18 is much better to use ,it certainly isn't a POS!:p.

but still off from what the BIOS said right at boot up before even loading winblows.

I take it you didn't calibrate MBM then ? that's hardly the programs fault! ,next time add compensation to MBM to match the bios readings & it'll be fine. (you can do this by measuring cpu temps whilst idle with a software cooler on ,then shutting down to the bios to see the difference.That'll give you more accurate readings ,though it won't be 100% right)

Supersix

No, that Abit motherboard is a POS

No ,it isn't ,its well known that the KT7 is 1 of the best Athlon boards about , he was mistakenly slagging off MBM because he didn't know how to use it properly ,slagging off his m/brd hardly resolves that!

Shinnertech
I'll shout you on ICQ to see if your MBM readings a about right ,but it doesn't sound like it

since someone asked and i'm not sure if it was answered:

RC5 is an encryption algorithm designed by a fellow at MIT in the late 70's and 80's. The RC5 we are talking about is a competition sponsored by RSA labs in wich there are several messages encrypted with different levels of security. The first competition was encrypted with DES-III and was broken in a few days. The second uses RC5 and a 40bit key, and they go up in increments of 8 bits from there all the way to 128 bits. Currently we are on the 64bit competition. What makes this competition so huge is that there are 386,250,703,896,576 different combination of keys and modern pc's can only check 2-3 million/second. Basically there's no point buts it's kinda fun to beat people with a faster computer and spread your manliness around. For some reason this contest isn't to popular with the ladies. I don't know why:D

Hope this helps. If not go to www.distributed.net and www.rsa.com and search for secret key challenge or something along that line.

NFS4:
Glad to hear your overclocking is going well!! I'm not having such luck. what fsb are you running and what clock? My fsb o/cing is horrible. I can't even overclock my fsb passed 110 with kingston value ram 128mb pc133 infineon chips! The highest clock I can use is 8. As soon as I try 8.5 or 9....it doesn't boot and I have to clear cmos and try again. I've tried raising the voltage but it hasn't been helping too much. What bios are you using? I flashed mine to wzb01 to disable the need for a cpu fan attached to the mobo. Any tips you could throw my way?? The highest I'm gettin is a little over 800. Thanks bro!

Zero, I haven't done anything special. I'm using the WW BIOS dated 12/15. I have my Duron running at 952MHz (7x136) @ 1.775 volts. Everything in BIOS is optimized for speed.

I went shopping for a couple of hours, left RC5 shut off, just AIM and UPS software running essentially, and when I got home my CPU and system temps were both at 20 degrees C. :)

I'm using the monitoring program that came with my EPoX MVP3G5 motherboard (SS7 board of course). When I switched to Duron/Athlon platform with the KT7-RAID, the monitoring program provided was VIA's, and it was horrible. It didn't minimize to the system tray, so you were stuck with a taskbar item, and when it was open it took up 3/4 of the screen, most of it empty space. The settings also were difficult to understand. So I tried the old monitoring program that came with the EPoX board, and it works fine with the Abit board. The only difference is that the CPU and System temperatures are reversed, but they are as accurate as the VIA monitoring program was (judged by switching back and forth between the two programs to compare).

hmmm. I can't figure out why I can't get my fsb to o/c much. Could it be the bios?

<< I'm using the WW BIOS dated 12/15 >>



The WZ Bios dated 01/12/2001 (B2?) has better memory timings. Of course you need GOOD memory to realise this! It also allows you to turn off that silly cpu fan protect feature that keeps the system from booting if a RPM signal is absent on the cpu fan header.

Cheers!

Of course it hasn't. You wouldn't boot IF it did! I'm using a two lead fan (no tach signal) and the board with WW or higher will NOT boot without it.

It's a feature that has merits, but it should still have a toggle. Future BIOS will incorporate it. I'm using it. :)

Cheers!
