Hi Guys,just a little confused,still trying to deal with older systems for my better half,who still just wants the older system.Make sence? ok here we go,right now she has a Athlon 1Gig cpu socket 462 on a Gigabyte Ep-8RDA3+ motherboard with 512 meg Dual channel pc3200 ddr 400 ram,the ram is only running at 100mhz,and it's ddr 400,kinda slo going to boost her up to a Athlon XP 2600+ Barton Chip AXDA2600DKV4D,and 1 gig 2x512 Dual channel ocz pc3200 ddr 400.do you think it will make a difference at all? It's going to run at least 333mhz,instead of 100mhz..Question I have,Do I set the ram to run at SPD witch is 400mhz,or auto witch will be 333mhz.Whats the best way to set this 2600+ XP,with 400 DDR?? to run at it's best.Thankyou for any help on this.
