Grr... my Athlon won't go above 1 ghz

[futura2001]

Grr...
My Athlon (original) will not run any higher than 1 ghz. Bought it as a 750, and found out that it has a 950 core, got Mathlon, set the cache to 1/3 and cranked it up to 1 ghz with my goldfinger. Unfortunately it does not go any higher. The cache is running at 333.34 mhz, and before I used Mathlon, I was able to get the cache up to somewhere around 365 to 380 stable. Counting that the core is rated for 950 and most athlons overclock 150 mhz above the core rating, what is holding me back?

Well you have been here a few weeks and I am sure you have heard 'what are your system specs?' many times before... i will ask you what are your system specs? What are you using for cooling? What are you CPU temps? There is a possibility taht you can hit 1g but your overheating your chip at defualt speed due to inadequate cooling. look into taht.

Okay, here goes:
Athlon 750 with 950 core running at 1G with a Northwind GFD 2.0
Abit KA7
639 megs Kingmax TinyBGA pc133
Oxygen VX1 32
2 Caviars with 10g total

3 Case fans and a Globalwin Vos32

It runs at 42c full load

Get your temps down, The VIA KX133 chipset on your board is very senseitive to heat (at least mine is)...Fastest SLot A I have seen is 750 at 1100(110x10.0), and thats Ottomans, its watercooled. You need to check the contact between the heatplate and the cache chips.....yeah they risers but they still dont touch, So you need to cool the chips,I have seen people insert sanded down pennies to make teh full contact along with thermal paste. If you can at all, get some air over teh KX133 chipset,this helped my board ALOt when I managed to get air going under my huge heatsink....

Thanks
Sanded down pennies?
That sounds easy enough, I suspect you mean the ones before the 80s that were 95% copper instead of 95% zinc...
How effective is the heat transfer plate? I am thinking of just taking it off all together and putting my chip directly on my Vos32. The cache wouldn't be cooled there, so I could stick a couple of pieces of silver or some pennies on them to keep the connection, how effective would that be?

Doesnt really matter how effective just as long as they are cooled...err the heat is being taken away...but as long as it sits there on the chips your not gonna have much lucky...heck a big gob of thermal patse as a connection will work...( i used to do that before pennies...) But the more the better...

But my Slot A is retired from mian rig to Lan Rig to now a Entertainment rig that sitz beside my TV and plays DVD's through the video out...

BTW how do you plan on mounthing the heatsink without the heatplate?

I have always wondered why AMD never made the heatplate actualy touch the cache chips...

my first real o/c was with a 750 classic. the best performance i got was 110x9 for 990. it would run fine at 10x100 but i couldn't raise the fsb any with a multi of 10. i tried. believe me. you hit 1000 with it, i'd be happy. i'd drop the multi one and raise the fsb if you can. the performance will be much higher even with a lower clock spd.
