New Motherbrd & AMD CPU probs

[WHUB]

New Homebuilt PC.Gigabyte GA-7DXC MB AMD 1.2GB CPU, 256Meg DDRram, WIN98SE, 32MegDDR G-Force2 graphics, SB-Live sound


Problem is right after I built this I started Having heating problems from my CPU [140 F]I also started having problems with freeze ups in intense graphic gaming. The games had CPU useage indicators displayed onscreen so Icould see some terrible hits to the CPU [from 6% to 87%!]These hits would last for 10 secondsand then fade off. This would reccur every 3 to 5 minutes. Sometimes this would happen,sometimes it wouldnt. I dont think temperature was the cause of this. Anyway,I bought new Mini- Super-Orb dual fan heatsink for my CPU and as soon as I installed this thing[with the heat sink grease applied] my temp shot to 150F and up to 160F[shutdown limit]. I carried to local shop and let them test my equip. to see if they could help.
What they told me was the core voltage on my MB should be 1.7v and my bios was showing 2.8v! This is a jumperless MB and there is no way to alter this and this has caused all my problems with CPU and that is now fried and wont run in any other MB they have there without skyrocketing to 180f! Anybody have an answer to whither this is correct or what.. What do U think??

fixing the heat problem may fix it all, have you tried adding some thermal compund on the cpu to help keep ot cool?

[WHUB]

Tried everything...now they say MB bad because of core voltage unfixably high andthat has fried CPU. I need to know if symptoms I showed would result in MB bad and killing CPU??? This is rather expensive ordeal forme

who said the core voltage is unfixable high?

[WHUB]

Jumperless MB no way to adjust voltages on core

[MadMax]

Based on what I see in the online manual.....
GA-7DXC auto detects the core voltage and is not adjustable.
It supports Socket A for AMD Athlon™ /Duron™ 200MHz FSB processors.

There are two flavors of Athlon 1.2GB. One has a 200 FSB and the other has a 266 FBS. Both run a core voltage of 1.75v.

Your GA-7DXC is not detecting the correct core voltage.
a. Maybe your processor is a 266 FBS'er and the motherboard can not properly detect it.
b. The motherboard is defective and can not properly detect core voltages.

MADMAX it is 200fsb board and chip is 200 also. Now I am pretty sure that MB is bad, but, would it fry the CPU chip and actually cause damage around the edges of it[deteriation, flaking] or did the folks damage it pulling off heatsink and installing heatsink? I was having problems before changing heatsinks with CPU hits that would render computer just about helpless for 10 secs on every hit that came 3 to 5 min when it would do it....sometimes it wouldn't.

Ok, no TBird or Duron in existence could tolerate 2.8 volts for more than about two seconds before they were totally and completely fried, and no Socket A motherboard will even give that many volts to a CPU. The upper limit per the data sheet is 2.1 volts, and that could only be done with very good cooling and actually modifying your motherboard to get it to go that high in voltage.

I suspect that the shop you took the comptuer to is "looking at the wrong meter" so to speak. What I would try in your case are two things. One, make sure that the heatsink is directly in contact with an level with the CPU core. If it's not level or not making contact the heatsink does nothing.

Two, if there's "chipping" or "flaking" around the edges of your CPU after letting the people at the shop deal with it, it sounds to me like they chipped the core while swapping around heatsinks, and if they did so THEY may have broken the processor. If you can see "grey" inside the core around the edges, then someone has chipped it putting a heatsink on it.

If the cpu is chipped,it can result in skyrocketing temps,as the cpu is actually shorting,if that's the case,cpu is shot.
Carefully remove the cpu and look at it with a magnifying glass,any metal showing through?(slug area)
If so cpu has gone bye-bye.
A mini orb doesn't swing it,get either an Alpha,TiaSol,Vantec or GlobalWin Heatsink and fan.
If you're not familiar with the difficulty putting Socket A heatsinks on,try the latest from Vantec,it's clip design is the best around and is a snap to put on and remove.
Be forewarned,the Vantec's and GlobalWin come with the Delta 38cfm fan,which is the most powerful fan available,but also the loudest!
You may want to check here for different Heatsinks.

This is a good company and offer a wide selection.

That will explain temperatures skyrocketing after "shop" tinkered with it... the chip is definitely chipped. Im probably gonna be out $300 dollars. Now I hope MB is not doomed...they say it was bad...helll may not have been after listening to you guys! Geesh I will find out soon. I shipped the MB back with chip for replacement.

[Lawther]

wow i would take it back to the shop and demand a new cpu since they royaly fuked u over
