The Definitive Review Of The 128MB ACE PC133 SDRAM DIMM

The Test Setup

Processor	600MHz Intel Celeron II o/c to 810MHz @ 90MHz FSB
Cooler	Alpha PEP6U (YS Tech 5000 RPM fan)
Motherboard	ABIT BF6
RAM	128MB ACE PC133 CL3 SDRAM
Graphics Card	3Dlabs Permedia3 Create! AGP
Hard Disk	15GB Maxtor DiamondMax Plus 40 ATA/66 7,200rpm
Sound Card	Creative Labs Sound Blaster 32 ISA

Stability Tests

CAS 3

FSB (MHz)	Result / Comment	ALU (MB/s)	FLOAT (MB/s)
133	Stable	365	443
140	Stable	384	465
145	Stable	432	485
150	Stable (!!!)	410	498
155	CPU couldn't take it.	N/A	N/A

As you can see, the ACE PC133 CL3 SDRAM was amazingly able to reach an astounding 150MHz at CAS 3. Also, it was surprising to find that my friend's Pentium III 800EB was able to run stably with a FSB speed of 150MHz.

CAS 2

FSB (MHz)	Result / Comment	ALU (MB/s)	FLOAT(MB/s)
112	Stable	354	421
120	Stable	378	450
122	Win2K unstable	392	461
124	BIOS memory test failed	N/A	N/A
133	Won't POST	N/A	N/A

The highest stable speed was only 120MHz at CAS 2. Too bad this DIMM couldn't run at 133MHz with a CAS 2 setting.
