max safe voltage for everyday use on 965

[87dtna]

On my 550 unlocked to a quad it took 1.575 to get 3.9ghz stable. 3.8 took 1.50 Vcore.

I tried up to 1.65v once I bought a TRUE with an AM3 mount but it just would not hit 4ghz stable. Would boot the OS but not benchable.

Yeah I do have a C2. I'd love to get a C3 but it's really not worth the price for a little bit of OC i could get. I will probably just wait to see how the Thuban CPUs turn out.

This might make you feel a bit better, I'v just over clocked to a stable 4ghz
using two settings
17.5 x 230 @ 1.525
20 x 200 @ 1.525

Both hit a max temp of 52c under full load and avarage 35 to 39

Its taken me days to do this...

Now heres the part that will make you feel better I gained Appsolutly NOTHING on 3d mark infact my bench mark is slightly lower you would Deffinatly be wasting your money

Now compare this to my orginal bench mark
17.5 x 225 @ 1.4625v

Conclusion is clear , Clocks may read higher but actual throuput is not

If you aren't getting a higher score than before then something is clocked lower or something is unstable. That or the run was bugged

I duno iv spent 3 days trying to beat this benchmark , I can get the clock speed up higher over 4ghz but the bench mark drops even though its stable this is the appsolute best i can get

17.5 x 228 @ 1.475v + ddr upped to 2.1v

Anything above 3.992 and the score drops

Anything up to 1.55 is safe but often unneeded, have a play around with voltages until you find what works best for your cpu and mobo combo
