With these settings I am able to run prime stable for more than 4 hours. So now I am trying to get to the next step, which for me is 3.4 or 3.5
. So I tried putting 1600 for the fsb with no change to the vcore and one or two of the prime worker threads got a rounding error, so then I tried to steadily increase the vcore, but it seemed that whatever I increased it to, I would still get this rounding error no matter what. I went as far as 1.475 (in cpu-z went up to 1.4) but still received this prime error. I then tried to increase the nb/ht voltages but I wasn't sure how much i was supposed to raise it or what the max is. The max temps the cores would get at would always be under 68 celsius.
So now I am lost and I am not sure exactly where to go from here to reach my goal of 3.5 ghz.
(I do plan on getting a rifle CPU cooler to get those temps a lil lower)
So again, at 3.18 ghz I am stable with these settings:
vcore: 1.41250 (~1.35 when running prime)
dram: 2.21 (4-4-4-15)
Thanks for any help!
wow you have a serious vdrop, I would recommend you to do the vdrop mod linked on the first page, that could help you get some extra mhz.
the 45nm cpu's love ht volt, so you could try to increase it to 1.42-1.46v.
and maybe add some nb to, that could give some result (maybe up to 1.44-1.46 there too, but actually you can try to decrease it to 1.34-1.38v, some 34nm's liuke less volt)
also when testing, put the latency on the ram higher, just to make sure the ram is not the problem.
please excuuse spelling and so on, im drunk now lol, but I did my best to try to spell right heh
