I had only an hour or so to play with my new RAM last night. But it seems that i recived a realy bad batch or this RAM is just very picky on timings and i havent found the right combination.
i lowered my multi to 6 to rule out cpu as a limiting factor.
I started with 250fsb at 2.7v and that booted windows fine. Then i i tried 280 and that booted into windows. I left RAM timings all on auto and it seems that its being detected at 2.5 ,4 ,4 ,8 and not the rated timings of 2.5 ,3 ,3 ,7. Anyhow i was optimistic seeing as i could already boot windows at 280FSB. Then it all went downhill. I tried 285FSB and it almost gets into windows then reboots. I tried upping the vdimm as high as 2.9 and that didnt help. I tried using a vcore of 1.7 and that didnt help. I tried upping chipset voltage to 1.8 and that didnt help. i tried CAS 3 and that didnt help. So i gave up and went back to 280. I tried to load World of Warcraft and i quickly get a merrory error and the game crashes. This also happened with Steam. I tried going down in 5FSB increments and this kept happening even at 250FSB. SuperPI wouldnt even run. I finally was getting very short on time so i just put it all the way down to 220FSB and it seemed to stabalize and superPI and WOW would run without crashing.
Now my old RAM would do 250FSB at CAS2 using stock chipset voltage. So im pretty sure its not my mobo holding me back. I also booted windows at 300HTT with my old RAM using a divider. And i could game at that HTT if i remember correctly. So i dont believe that my CPU's mem controller is to blame. I was using slots 1 and 3 which was what had been working for me. I even tried using the 2 slots closest to the heatsink, i think thats 1 and 2. Anyhow that made no difference.
Could someone with the same mobo and RAM as me post thier exact memory settings in bios plz? That might help me.
Im not sure what to do now. Will giving voltage above 2.9 realy make a difference? It doesnt seem like ppl with TCCD ever need that much.
So any suggestions are very welcome. Thanks
