impact of ram on overclocking

[jordan]

hey guys, I have a unlocked 1ghz tbird on a abit kt7overclocked to 1.2 (multiplier of 11 and fsb of 106)- I can not get it any higher than this, is it my ram holding me back? I just using 256mb generic pc100

my voltage is at 1.85 and my full load temp is 52C using a global win fop38

any help would be appreciated, thx!

Sounds like your temps are too high to me. Are your temps normal when you boot in default settings?

If tis generic RAM, then it probably wont go much further. But your Processor is Deffinately too hot. It should be near 40C at full load. What type of heatsink you got on there?

[AKDUDE]

Did you use the right amount of thermal past? And hopefully you used a silver based compound. It only takes alittle.
I would think that with a FOP38 your temps would be lower, at least by ten degrees.
What do you have your voltage set at? Maybe you should lower it a little, and see if you can still boot up. That my lower the temp.

Watch out if 1.85 is not too high !
And also watch a REAL voltage, not only in SoftMenu 3.

I am using a global win fop 38 and running a open case- ( just the stock setup pad, i didnt use aftermarket thermal paste)

it wont boot stable at this overclock with anything less than 1.85v- it is runing rock solid, no hangups or glitches, so should i still be worried about temps? The via hardware monitor temp guage has never gone past 52C and that was with using the sisoft sandra burn in for 100 consecutive runs

Lose that HSF pad and go to thermal paste. That is the problem. While you're at it. Lap the FOP-38 base. It's the same HS as my FOP-32 and my base was very rough before I lapped it. Do those two things (right) and I guarantee you better results.

what does LAPPING mean?

[Hoot]

Lapping as it relates to OCing is simply improving the finish on the heatsink base surfact to remove manufacturing marks and generally ensure flatness. This will improve the contact with the CPU core for optimum heat transfer efficiency. It is accomplished using sandpaper sheets of decreasing coarseness on a flat surface. There are innumerable Web pages on the process. Do a power search containing lapping + heatsink and you will get around 300 hits.

What type of mother board are you using?
If you get better memory, you can up the front side bus, and drop the multipllier.

no... he's using a kt133-based board. it's quite possible that it's maxed out at 106fsb. mine tops at 107 but a mate's at 113. it's pretty much luck of the draw with kt133 boards. the kt133a-based boards are the ones that give the nice, high fsbs.
