C300A @ 450 for 4 months = FRIED!!!!!

I know this is a sim NG.. but I know a lot of people use this system.. and thought they should know... I bought a new system about 4 months ago..: Celeron 300A (Malaysia Week 47) Abit BH6 m/b 64 PC100 ram Since then.. I have put in : Voodoo 2 card Monster Sound MX300 card Network card.. (10baseT) I have been running GPL plus other apps.. and fairly processor intensive programs.... volts... RAN GREAT!!!!!! I was thrilled.... THEN.. I decided to buy some more h/d last week... went out and bought a Seagate 4.3 gb harddisk.. I installed it.. along with my orignial.. turned on the power.. NOTHING!!!! So I was then mucking around witht eh calbes.. tried every combination.. I finally took it to be installed.. and they said they could find anything wrong execpt maybe the m/d was damaged... I then took it to wth supplier of the b/d.. and he tested it.... He took out the 300a and put in a 333 and BOOM!!!!!! IT WORKED!!! I had damaged my c300a :-( than 33 degrees C. on the m/b I eventually had to get a 333 cheap.. to replace the 300a... and now it only goes to 416 (5.0 x 83).. but not 500 (5.0 x 100) yet.. DOES anyones know of any tricks to try to get this stubborn cput up there??? I know the o'lcock web sites.. etc... I went thru all of them.. read everything.. the 333 is a crappy oclocker cos it won't do the 100 fsb speed.. which is a bummer :-( I think you wil find that I just got REALLY unlucky... and got a wierd cpu.. I wouldn't think this ais the norm... and wouldn't like to discorage ppl from doing this.. it is great.. Any sudgestions??? James Pickard, Melbourne, AUSTRALIA

I hope that when you were fiddling with the new hard drive and plugging in and out connectors you were discharging static electricity? Is it possible that you might have fried the CPU during HD installation? Just a thought.. Nafi Coker Pickard wrote >I bought a new system about 4 months ago..:

Yes. Seems like too much of a coincidence to me too.

Yeah, it sounds like static electricity to me, also. Generally, to discharge static I like to stand barefoot in a pool of water as I grab hold of the case and power plug simultaneously. :-) Actually, prior to touching any of the internal boards, I always clip an anti-static strap to the case frame and discharge any static build up. That won't help you now, but it's something to keep in mind next time. --- Jet Jaguar I have a spam blocking address. Replying to me is like pulling teeth.

Just coming into this thread. I don't believe that you fried your CPU at 2,0V. But this is a case for the overclockers-newsgroup - they are desperately waiting for "fried-CPU" -input. Jens --------------------------------------------- Remove "NOSPAM" before using my email-address

What probably happened is that with the second hard drive, you are getting a voltage drop across your motherboard, so your CPU can't run at 450 at 2.0 V, either set it back to 300, or increase the voltage to 2.1 or 2.2V, if your board supports it. Marc

I suppose this voltage situation would also apply to PCI cards. I pulled my V2 and Matrox last night, and replaced them with a V3. I am running at 2.3V right now. Maybe I could find stability (and relative comfort, leaving 2.3V behind) at 2.2V with the reduction of a PCI card? Brett

Actually I experienced this. When I got a second Voodoo 2 card I had to lower the speed of my C300A to 450 (from 464- due too RAM stability issues). Regards K.S. Br?nnick

I don't believe it either considering I've been running my Celery at 2.7 volts(!) on and off since last October and I'm still using the same chip. That person was full of it. Probably he's one of those folks that believe you're "stealing" from Intel because you're overclocking.
