athlon64 overclocking
I was reading a review of the Aopen AK86-L Via motherboard and the guy
mentions: http://www.anandtech.com/mb/showdoc.html?i=1959 "By dropping multipliers in the BIOS, we were able to reach FSB settings as high as 252. It appears that the AGP/PCI is ratio controlled and that it again drops to 33/66 at a setting of 234. This means the 252 is a PCI/AGP overclock of about 19 which is in-line with the maximum overclock our picky ATI 9800 can handle. This is not a working PCI lock as we have seen on Intel chipsets; it is a ratio-driven PCI/AGP frequency similar to the one we first saw on the Abit K8T800 motherboard." Sounds to me like he's saying at FSB: 234mhz you get the correct PCI/AGP frequencies. 10 x 234 seems to be more than the athlon64's can handle, but you can drop the multiplier below 10, and at 9 x 234 = 2106 which seems to be something they can handle. It also looks like the athlon64 2800 (1.8Ghz) with a multiplier of 9 would work out well with this motherboard at this FSB. Unfortunately, they tested the motherboard with the BH5 chip ram that's almost unavailable anymore, so one wonders what working ram you're supposed to put in the damn thing Anyone playing around with this stuff ? By the way, ram prices have been rising. Suggests the computer vendors are building computers (939 ?), or buying the memory now. |

I need the extra ram so I have all three sockets filled which cuts me down to 200 DDR and that allows me to boost the fsb to 220. It's a good tradeoff for what I need. The fsb will go higher but it's very stable at 220. I need many programs open at once and a gig of ram isn't enough, too much swapping. I plan to get 2 1GB chips soon and will run it at normal clock then. |
