My Duron 1.8 GHz is running at 1350 MHz

OK, this is going to sound way out weird. I just built a system with an Asus A7V600-X motherboard, a Duron 1.8 GHz CPU and 512 MB Kingston 400 MHz non-ECC RAM.

I installed an unofficial service pack for Win98SE and now I find myself locked out of my own BIOS because the supervisor password has enabled. LOL

Anyway, the CPU speed is at 1350 MHz and I'd like to get it up to 1800 MHz. But I read on the Tigerdirect website (customer review) that this CPU is not compatible with aluminium heatsinks (apparently better with copper). I have a Spire Whisper Rock IV which I read is aluminium but with a copper core. I also read that sometimes your motherboard sets the CPU speed lower when it detects too high a temperature. Maybe I should add also that when I placed the heatsink for the first time, I had it at an angle. When I noticed it, I hadn't turned on the machine yet so I put it back on correctly without taking out the white thermal paste and replacing it with thermal grease. (In other words, the original thermal paste is still on.)

My machine works fine. As a matter of fact, I get between 30 and 70 frames per second in Unreal Tournament 2004 with a Ti4200 (I found brand new) and the game looks great.

So, if I solve the problem of not being able to access my BIOS, how do I increase the CPU speed? Do I just highlight the CPU speed and press the + button? How can I check the performance of the CPU to verify it's working like it should? And how can I check the CPU temperature? (I now have WinXP Pro but I intend to dual boot later with Win98SE & WinXP Pro.)

I have a case temperature readout on my Enermax case and with the probe at the bottom, it's usually around 32' Celcius.

Thanks, if you have any suggestions. Yeah, I know my Duron 1.8 GHz and Ti4200 are real cheap but, I bought those to learn how to build a system. I'm waiting for dual cores to get cheap and the Geforce 8 line to come out. UT2007 here we come.

That makes no sense... anyway, unplug the system completely and remove the battery on the motherboard for a minute while also setting the clear CMOS jumper for good measure. That should reset everything in the BIOS to default, including the password.

Ok, it's definitely not the heatsink issue. Your heatsink should be fine, assuming that it was applied properly and is making good contact with the CPU.

It sounds like the FSB is set wrong; your processor needs a 133MHz FSB (133MHz*13.5=~1.8GHz), but the board defaulted to a 100MHz FSB (100MHz*13.5=~1.35GHz). Change this setting and you should be good to go. :)

If you are able to get the FSB to 133, why not go to 166 for good measure? That way, if it'll get hot (if that is the issue) it'll automatically get back to 133 (if I assume correctly). Anyway, overclock the hell out of that thing, no mather what you do.

By the way, aren't you meaning an Athlon? The Duron's only got to 1400, I believe.

Vegitto- Im pretty sure Durons made it to 1800.

EDIT: Yeah. Theres an 1800 right on the top of the RTPE feed.

Let's make a fact of Duron/ Xp/ Sempron life very clear before taking this too far. Between the Athlon Thunderbird cpu's and the first XP's, AMD changed its naming conventions. A Duron 1800 actually does have a calculated speed in the 1300's of MHz.

The Thunderbird 1400 was the last AMD chip that ran at the speed in its name. But AMD cpu's didn't have to run as fast as Intel cpu's to do the same work. The XP 1600 and the older Thunderbird 1400 both were 1.4 MHz cpu's, but both were able to do more work than a 1.6 MHz Intel cpu (thus the "plus" in the performance rating).

Durons and Semprons apply a different performance rating, since they are compared to Celeron cpu's, not the full- fledged Intel products. A Duron 1600 would've topped out at roughly 1.1 MHz in order to be matched to a Celeron 1.6. There are nice charts to refer to here:

Yeah those Durons did have 1800mhz, I had one unning at 1970 or something a while back, not a bad peice IMO. Up that thing to 166fsb and be happier.

Ah, I see you have an Asus A7V600-X. Did you have the Duron 1.8 GHz on that mobo? If so, did it damage any of your components when you overclocked it like that?

No I had it on a POS ECS K7V TA3 mobo, it worked 'ok' at 166 but I couldn't adjust the voltage so it wasn't all that stable. The Asus board should do a great job with it though, although I think mines dying cuz it took almost a hour to get it to post the other day, strangely enough I had to clear the CMOS and disconnect the spare HDD and firewire card to get'er to start so I don't think its a good example for overclocking.

LOL. OK, thanks for the input.

Well, I'm happy because I did get it to 1800 MHz finally!

And there is an improvement in performance in UT2004.

I unplugged the system, pressed the power button, took out the battery and took out the jumpers near the battery and put them on the lower two pins and put it back in place several seconds later. Booted up and pressed Delete to enter BIOS. I reset the BIOS settings and highlighted CPU speed and pressed enter. Set it to 1800 MHz. Man what a relief. :)

I want whatever kiwi is smoking, on that link he provided, if you go to the Durons, it clearly states a Duron 1800 is 1,8Ghz, the silly ah heck!

Anyway, yes, clear your BIOS, I have never come across anything that locks you out the BIOS by doing something from inside the OS, learn somethin new everyday.

I might be wrong about that. Hey, if I change the FSB to 166 MHz, do I need to change the voltage???

try changing the fsb and if it works without any hiccups, keep the voltage where it is, if its unstable then try .05 more and go from there.
