If you can find some PC150 SDRAM, you might try that if your current memory won't go past 137 MHz. You could also try using a 2:3 divider (if available) to drop it down.
PC150 memory wasn't around that long before DDR supplanted it and it disappeared.
Although you can find nice sticks that aren't classified as PC150 but they can do 150, even at the tightest timings. I've just gone through a HDD box worth of SD sticks and found some of these kinds that could do 150/fastest in whatever board I tried them in.
16-chip 256MiB "BX friendly" sticks that could do at least one pass of GoldMemory (it was convenient, most of these had been 1-pass memtest86 tested in "the other" board at 143MHz/cl2/turbo) in a P3B-F, 150MHz/2-2-2-5:
Hynix HY57V28820HCT-K (and I had to throw away every -H as they weren't up to the requirements)
Micron 48LC16M8A2 TG 7E-E
VDATA VDS7608A4A-75G (I don't know who the original manufacturer might be)
Infineon HYB39S128800CT-75 (funny enough I had more success with these than with the -7 parts that should be faster on paper)
16-chip 512MiB modules, one pass memtest86 in an MSI 694T, 150/cl2/turbo:
Quimonda HYB39S256800FE-7 (I have a bunch of CSX sticks with re-marked chips, the ones on this one were left alone for some reason)
Of course it doesn't mean that all of the chips with these specs can do 150/cl2 in any circumstances.
Shame on us, doomed from the start
May God have mercy on our dirty little hearts
