Chrom Orb no good?

[jaydee116]

Someone tells me the Chrom Orb HSF is not good for overclocking even if your heat is down? What differnce does it make if your temps are good? He said he could post higher with other HSF but not as high with the Chrom Orb. Any input would be usefull being I have a Chrome Orb and trying to get past 850 with a Duron600.

Chrome orb don't cool very good, they are not good for overclocking. You should get a FOP32-1, FOP 38 (if you can stand the noise), Alpha pal6035 or a hedgehog. They are among the best.

Its okay for non-overclock sub 900s... Mild overclocks at low voltage/950 can be adequate cooling.

You can do better with the taisol cek733092, though

Some diode versus socket-thermsitor test results: Here.

My temps are: CPU 40C idle, 42C full,MB 24C. With the following specs:

A7V 1004d
Duron600@787
FSB@105
Multi@7.5
Vcore 1.62/1.65 (prob,MBM,Sandra, reads 1.70)
VIO 3.3
320 megs PC320

He explained to me that the Orb itself was the problem not the temps?
Does this make any since? If the temps are low enough why would the Orb make it not post?

 

[Mikewarrior2]

because the temps are "inaccurate" with any socket-thermsitor setup... your actual core temp is probably higher, so that may be why the CPU isn't Posting.


Nevertheless, the ORB should be able to handle your cpu speed... Are you using thermal grease? is it sitting flat on the cpu core?

Yes, thermal grease, and I cut the little rubber bumpers on the four corners of the chip to make it tight. It clips on very tight. i remember you rep[layed to one of my other posts about the temps not being accurate. But if it reads 40C it still shouldn't be over 50C should it? If I set the Vcore at its highest level and the multiplier at 9X,and the FSB@100 the computer will just start the beeping and not even fire up. I think maybe it is the memory. I have two chips of PC133 128megs with "LD" brand on them, and another chip that is 64megs PC133 with no name on it.

I also have a 80mm fan blowing on the ORB, a 80mm fan in the rear blowing out, and a 4.5" 85cfm fan in the front blowing on the MB. The rear 80mm and the 4.5" fan run off a seperate power supply and everything else is off the comp. 300watt supply.

Is a Gold Orb any better than a Chrome orb?

 

[Mikewarrior2]

No, it shouldn't even be in the 50s even... As long as the heatsink is mounted flat on the cpu, you should be able to post, save the possibility that your cPU is at its limit.

I maxed out the voltage (1.85) and it posted at 900 with FSB100. But I got error messages once into windows. Need more voltage but I am not going to mod the board. I have it set at: FSB103, multi 8X, Vcore 1.675/1.70, VIO 3.56, and it runns good. Temps stay low and upping the FSB@103 gave to memory a good boost according to SIS Soft Sandra.
