Tweak suggestions for i7 880


Recommended Posts

It has been long time since i last OCed my i7 880 (and / or played an ED title) and i have totally forgotten how i OCed the thing. If i remmember correctly the 3.73 GHz max turbo freq is achieved with load on a single core? (edit: yes. the scaling factor scheme is '5,4,2,2," -> 3059 (stock clock) + (133 x factor) = Turbo freq. for active cores: "1,2,3,4". Or multiplier increase over the stock multi (23x) as + "5,4,2,2" meaning a 28x multiplier with turbo when one core is active. Note, disabling HT lowers the maximum Turbo multi by one (28x->27x), at least on my system. )

 

What you estimate would be the minimum OC that would add at least around 10fps increase :

 

Just runing ED titles on a single (3.73 GHz turbo) or two cores (3.60 GHz turbo) would be enough or is necessary to have a full time OC on all cores and in that case what would be the minimum freq necessary to make a worth difference in performance and again would be worth running in only 2 or 1 core ?

 

Thanks :)

Any suggestions maybe on how to utilize best this CPU for DCS / FC3 ? Or if maybe theres no worth gain in doing anything more than to run this CPU everything stock (HT enabled, stock intel turbo, all cores enabled, no affinity changes for DCS / FC3, no clocks increase etc)
