Hyper Treading On/OFF ????

[FullArson]

Hi,
I have a i7 950 @ stock speed. The only thing I overclocked is my ram: 1600 MHz (9-9-9-24 @ 1.65V).

So before I installed my Hyper 212+ I had the stock cooler and HT On; My temps were
Idle: Around 46-48C
Laod: Over 82C, so I stopped the test.

So I Installed a Hyper 212+ heatsink, but I think my temps are a little bit high with the hyper 212+ cooler Installed and HT ON.
Ambient temps is presently 24.5C in the room.

I have applied MX-2 thermal paste.

Idle: 40,38,39,38
Laod (small FTTs): 74,71,68,68 after 15 mins.
Does it look normal ?

So afterwards, I turned HT OFF and I had
Idle : 40,36,40,36
Laod( small FTTs) : 64,60,60,56 after 20 mins

So we can compare Before and After I turned HT OFF.
My Question is, Should i leave Ht OFF, So my CPU doesn't heat or should I turn it back ON ?
What difference does it make on performance.

Thx alot guys.

on if you fold,render etc.

off if you game only maybe>?

most games wont benefit from the extra 4 threads,last i checkered.



edit temps look ok. it throttle around 90c or close to. dont be scared of mid 70's low 80's.
ive built fanless machines that go on liek that all day long

I am getting similar temps on a i7 920 D0 with a Tian Finair. with hyper thread on. 75 77 c

198.5 x 21, 1600 ram

Cant Prime it have bridge heating I think.

Cibench is good though

edit 185.5 x21 1600 ( 80 81 c) prime small fft

that's normal, i wouldnt worry to much, and unless you fold you wont be seeing that kind of load any other time.
how did you apply your thermal paste? on my 212+ i spread it over the heatspreader with a credit card and it seemed to drop temps about 2-3 degrees.

I used MX-2 thermal paste.

I've applied a very thin layer on the base of the Heatsink and I used the vertical line method on the CPU.

Before Using the vertical line method I've tried to spread it with a credit card....Didn't see a difference.

you have to use a little bit more thermal paste with the 212+ and other direct touch heatsinks, to fill in the groves in between the heatpipes.

Hyper treading....LOL.

That's all I have to contribute

I remember when HT was first introduced (Pentium 4 / Pentium D Extreme) some applications actually slowed down due to it being on, but that's rarely the case anymore.
I'd keep it on, unless your CPU is throttling because of the heat - check CPU-Z if the clocks drop after something (not necessarily the CPU) hits a certain temperature while stress testing.

This is on a socket 1155 CPU but here's a little idea of what HT can do for you: http://www.tomshardware.com/reviews/...i5,2410-5.html
Essentially it will boost performance in applications that can't get enough threads, like transcoding, rendering, image editing, etc. Games have barely started to use 4 threads, and even then they don't use all four to their maximum effect.
