It gets so hot you can barely keep a finger on a cooler (its a really small cooler without a fan).
Anyways... I dig the computer up to try and do some overclocking, checked the settings and this 233MMX was set to 2.1V and ran Win98 just fine. Changed the FSB to 75MHz == 266MHz and I had to raise the voltage to 2.3V. Finally the 83MHz FSB. At 2.3V it wouldn't even post. So I raised to 2.7V. It booted to DOS, ran 3Dbench but Win98 gets Protected Memory Error. Raising voltage to its Default 2.8V fixed it and runs happily at 292MHz even though BIOS reports as 266MHz - Aida16, Aida32, Memtest, Sysinfo, 3Dbench agree its 292MHz. As I don't have any Super 7 boards this is it...for now 😉
3Dbench 1.0c results:
66x3.5 = 233MHz... 175.0
75x3.5 = 266MHz... 197.4
83x3.5 = 292MHz... 218.9
Memtest 3.2:
233MHz:
L1 Cache = 174MB/s
Memory 64MB = 144MB/s
266MHz:
L1 Cache = 197MB/s
Memory 64MB = 162MB/s
292MHz
L1 Cache = 218MB/s
Memory 64MB = 180MB/s
Hope to find some ss7 board soon.
PS:
This is the chip. It's actually missing one pin in the lower right corner - I don't know its purpose. 😕
Edit:
I used the wrong 3Dbench. Now retested with 3Dbench 1.0c @292MHz.
I also noticed that results varies with different PCI graphics cards (ATI Rage Pro 4MB is the slowest - 185.0, then S3 Virge 2MB - 205.6, Voodoo 3 3000 16MB - 206.8 and the fastest of my cards is TNT2 M64 16MB - 218.9. Almost the same is with Quake 1.06. Ati Rage Pro 4MB - 58.6, S3 Virge 2MB - 63.7, TNT2 M64 16MB 66.6 and fastest is Voodoo 3 3000 16MB - 66.8.
