Hey guys,
I have done some searching and reading around here.. and can't quite seem to solve my problem. Thought I'd appeal to the experts here.
I have an Abit IT7-Max2 board (version 1) all updated, etc. with a P4/2.4B CPU on it. I'd had ONE stick of 512 MB Kingston ValueRam (the DDR-333 PC2700 stuff) and was running the system as follows:
FSB at 150
Multiplier 18x (locked anyway i think)
H/W Strap: Low
DRAM Ratio: 3:4
and had left things like the timings and voltage at their default. I was getting some real great scores on SiSandra and thought I had the system pretty well-tuned and it was running great (except for a RAID problem we'll talk about another day..)
Well, today my new stick of 512 MB Kingston ValueRam (the same exact stick as my first one) showed up and I installed it. Yayy, a gig of ram. Well... XP will not even start with it at the previous settings. I basically have to come all the way back down to default (133 fsb, setting H/W strap and ratio back to default as well) and basically boot it at DDR266. I've tried tweaking the fsb back up a bit but XP just will not boot if I have the ratio at 3:4 and the FSB is raised much above 135-140. Just XP kicks in then the system reboots.
Any ideas ?? Thanks in advance for your input. I'd love to get it back up to performing where it was, especially now that I have twice as much memory. Seems a shame to gain the RAM and lose the speed.
