I have got a Cobalt RaQ 4r, the firmware was upgraded and Fedora Core 4 was installed. As part of the upgrade I wanted to replace the factory CPU with one that is listed as a drop in replacement... Of course, after spending
the money I wanted to see if there was any advantage. So, I found this
benchmark software and thought I would post the results.

CPU/Speed: AMD K6-2 450Mhz
Ram: 512 PC100 DIMM
Motherboard: Cobalt RaQ 4r
Bus: 1 PCI, 0 ISA
Cache: 64KB (on processor)
Controller: IDE ATA33
Disk: Seagate 20 Gig x 2 (Mirror)
Load: 1 user
Kernel: Linux 2.6
Kernel ELF?:

Now, from what I can tell... This Cobalt RaQ is the slowest of an of the computers in this thread!

Here are the results with the slick new processor:

If there are any people out there who are still using these old Cobalt servers (I know there are still lots in production), I also did some heat tests on the processor at the same time. With the CPU fan disabled (unplugged - but still using fin) at idle the stock processor was 35 C, running the benchmarks the temp went upto 65 which is still below the max temp of 85 for these K6 processors.

Doing the same tests, with no fan, the CPU at idle was about 40 During the benchmark it went to 68.5, so not much more. These measurements were taken with an infrared temperature monitor.
