I recently got my hands on an old Compaq Presario 4550. I don't plan to do much with it, but it's a neat little rig. I was testing the RAM in it a few hours ago and noticed that it had much more memory bandwidth than my 440FX based P2 box.
Here are the specs:
K6 at 233MHz
48MB PC66 SDRAM (16MB onboard+32MB DIMM)
proprietary Compaq board with 430VX chipset
512KB L2 on COAST
Memtest reported:
L1 cache: 1629MB/s
L2 cache: Unknown
Memory: 131MB/s
My Pentium II configuration:
PII Klamath at 300MHz
192MB of 60ns EDO (6x32MB SIMMs)
proprietary Deskpro board with 440FX chipset
Memtest reported:
L1 cache: 2937MB/s
L2 cache: 430MB/s
Memory: 75MB/s
I know EDO is slower than SDRAM, but that's quite a difference. And I would've thought that a PPro/P2 class chipset would have a more robust memory controller than a socket 7 chipset. 440FX owners, could you please tell me what kind of memory bandwidth you're getting in memtest?
This P2 always seemed to perform more like a fast P1, and clearly the alarmingly slow memory is to blame. Would upgrading to 50ns EDO give it a noticeable boost?
