narrow Posted December 23, 2005 Posted December 23, 2005 Hi all first post here and am trying to find my overclocking legs using the great guide on this site. I am pleased to have my opty up to the speed of a stock fx57:) but need some help with the RAM. have my opteron 146 upto 2.95Ghz and appears stable Prime95 for 8 hours Am trying to tweak the RAM Geil-value 2x512 PC3200 Get the clock speed up to 220MHz in Memtest (it's not great RAM!) anything above this doesn't boot even adjusting the timings/voltage. With FSB 200 and 1:1 ratio it works ok to DDR400. With FSB 295 I try to put a divide of 133 on the Ram but it doesn't boot. I think that I should have memory speed of 295(133/200)=196MHz. It will only boot on divide of 2:1 giving a measly 295MHz DDR RAM. Have tried increading the Vdimm and also slackening the timings (currently 2-3-3-5 through auto). Have tried bringing FSB down to 280 and still no joy. nothing seems to get the ram to boot any higher. Any suggestions, and be gentle, I'm new here :confused: Thanks Quote Share this post Link to post Share on other sites More sharing options...
