I have modified a HP PC by fitting the above CPU and MB in place of the MSI 7184 MB fitted with an S939 x2 4600+ CPU. The 4600+ was fitted to replace a 3200+ Athlon. I had used the same HSF for the 3200 and the X2 4600.
I decided to replace the MSI 7184 MB as it had a problem with PCI bus bandwidth.
I replaced the MSI MB, memory, and CPU with the CPU and MB mentioned. I re-used the HSF from the S939 CPU as it was for an 89W TDP CPU. The one supplied with the CPU was much less substantial than the S939 one. Once fitted, along with 2 gig of ddr2 800 memory the system booted up. After installing the drivers needed and re-activating XP the machine has been working fine.
I had tried running the system with an overclock to 3.00 gig before, but had not tested it much.
Today I have been trying to overclock the machine. The Gigabyte supplied utility is OK, but I'm not sure it reports the correct results. When running at the standard 2.5 Gig stettings with an FSB of 200 it shows the memory at running at 799/800. When I try running with a 12X mutliplier on a 200 Meg FSB (i.e. core speed of 2.4 Gig) the Gigabyte utility showed that the memory was not at 800 meg. As far as I understand a 2.4 gig core on a 200 meg FSB should be give a memory speed of 800 meg with DDR800 memory and 2.5 gig on 200 FSB should give a memory speed of 715 meg.
After a little reading up I have set the FSB to 240 meg, and kept the 12.5 multiplier. I also set them memory to DDR667, even though the memory fitted is DDR800. The reason for this is that 333 divides into 3000 and gives 9. This gives a memory clock of 667 * 240/200, which works out at 799/800. This gives 3.00 Gig for each core. At first one of the cores would fail on Prime 95, so I increased the CPU core voltage from 1.25 to 1.30. So far Prime 95 has been running on both cores for about 4.5 hours without error.
Despite re-using and old HSF, overclocking the CPU, and raising its core voltage the temperatures (at least reported by the Gigabyte easytune application) are OK. With Prime95 running on both cores the CPU temp is 43 C and the reported system temp is 34 C.
I'll report back later when the prime95 run has finished (i.e over 24 hours)
