Comparing versions 23.8 and 24.14 on a PIII. I already posted a summary of this in the thread Best version for Pentium III?. Version 24.14 runs a bit faster esp. for smaller FFTs:

FFTs above 4096K are only supported on SSE2 machines

Actually I met problem when I overclock my Sempron(2400), from FSB 166Mhz to 200 Mhz the Prime95(24.14) can never run anymore. I tried the stress test, result as attached photo.

Did you have any idea? I just seek for any consult. Thank you!

So looks a significent difference, but I can handle this override it.
I have tried to set CPU core Voltage from 1.6 to 1.625 and 1.65 no change.
also CPU/Ram interface: Enable/Disable no change

please help,

or I have to chang back to normal?

Looks like you are pushing your system beyond the actual possibilities of your CPU / cooling / RAM configuration. If your CPU has an unlocked multiplier then lower it to 8 - if you still get an error, then your RAM is your problem (you should change FSB/RAM divider to 5/6, or lower your current memory timings).
If "8" works fine then increase the multiplier until it's not fine, and then apply some more voltage to CPU, lower RAM timings, change FSB/RAM divider etc. Overclocking is all about experimenting

Got the Intel Dual Core P-D 930. Overclocked it to 3.6GHz/1.2750v. Damn 65nm is really nice. Memory is DDR2-533 overclocked to DDR2-640 4-4-4-12 running in Dual Channel. Asus P5WD2 Premium.

If I send you some executables and some data (source too, if you like)
could/would you run a lattice sieve benchmark on your machine, with both
processors running?

ckinason 2·11·109 Posts	For my overclock Sempron(2400) Actually I met problem when I overclock my Sempron(2400), from FSB 166Mhz to 200 Mhz the Prime95(24.14) can never run anymore. I tried the stress test, result as attached photo. Did you have any idea? I just seek for any consult.

I have tried to set CPU core Voltage from 1.6 to 1.625 and 1.65 no change. also CPU/Ram interface: Enable/Disable no change please help, or I have to chang back to normal? Attached Thumbnails

Cruelty May 2005 1624₁₀ Posts	Looks like you are pushing your system beyond the actual possibilities of your CPU / cooling / RAM configuration. If your CPU has an unlocked multiplier then lower it to 8 - if you still get an error, then your RAM is your problem (you should change FSB/RAM divider to 5/6, or lower your current memory timings). If "8" works fine then increase the multiplier until it's not fine, and then apply some more voltage to CPU, lower RAM timings, change FSB/RAM divider etc. Overclocking is all about experimenting
