i7 860 safe temps

post #1 of 16
Thread Starter 
Hi, Im running my i7 at 3.5 ghz, 50C idle and 70 C playing crysis 2 and 95 C during prime 95. Are those temps too high? My heatsink is a Zalman CNPS9700.
Also is it better to have HT off when overclocking?

Your temp is not safe when running Prime95.
If Prime can take your temp to 95 C, Linx might surpass 100 C.
May I know what your VCore?
Lynnfield is quite a hot chip. If you ran into temp issues, I'd suggest you to keep the VCore at stock.
Turning off HT can reduce the temp. But of course lower performance in multithreaded application.
But Games don't use HT. So, it should be fine for game.

Prime temp is definitely too high. I'd look into a new cooler.

my vcore is at 1.3 volts but what do you mean by Linx might surpass 100 C?

Linx goes a little harder on the CPU so it might push the temps even higher.

That is a ton of Vcore for such a conservative OC. I run my 860 at the same clock and only use 1.17vcore. Obviously you cant say all chips will need the same Vcore, but you should be able to tone yours down a little.

I was running some Prime95 a couple days ago for s&g's:

Agree with the rest, that vcore is too high for those clocks, turn down a notch or two in BIOS, test stability for an hour or so, then lower vcore again etc.

I've seen some 860s running 3.5GHz on 1.28V, so I don't think that's the issue. Heat however, is.

If you run programs that benefits from HT, I would leave it on. For games only, HT serves no real purpose.
