Hi, I was very motivated from reading guides in this forum and finally my computer parts arrived and built all my computer.
Here is my parts(Unfortunatly HD 5870 was defective and now im using hd 5770 cuz... i lost about 450$ and very sad... have to dhl back to united states and will cost me about 130$ just to get refund which is like only 300$....)


Well, After all the readings from forum here and there my eye started bleeding so I had to start OCing.

These are my settings:
I7-920 D0
bclk: 190mhz
multiplier: 20x
qpi: 16x
vCore: 1.258
IOH/ICH IO Volt: 1.5v
ICH vcore: 1.1v
QPI PLL Vcore 1.1v
CPU Pll vcore: 1.8(Auto)
IOH vcore: 1.1v
CPU VTT Volt 1.25v
DRAM: 1.55volt

Currently running at 3.8ghz , Memory: 758.1 x 2 = 1516mhz(8-8-8-29-tRFC:74)
Turbo: ON
HT: OFF

After runing almost 3 hours of OCCT to see if its stable.
Temperature of cores are around 66 to 71 Degree's Celcius on Full Load mostly around at 68to 69 and about 36-44 on idle.

While it was doing test I start reading about turbo and HT that both can make CPU to be very hot.
Also read some benefits between Turbo and HT. I decieded to turn off Turbo cuz it doesnt benefit me much however many people were saying even if I had to lower some MHz on cpu clock I should turn on HT.

This time I had to test out Turbo: off and HT: On.
However, the temperature went up around 69-75 degrees celcius with HT on.

I have two question as im very noob to OC.
1. Should I turn HD and turbo both to OFF to get stable at 3.8 ghz or should I lower to 3.6ghz and turn HT on?(I use computer mostly for playing WoW and Starcraft 2 beta or software development with VS2008)
2. From Data input I wrote about Voltages Am I putting too high on something?(NB Temperature looks very high with my board X58 Sli LE cheap one) If you see something should be lowered and tested out please let me know

Thank you very much

Edit: Looks like OCCT gives me very stable temperature between 61-65 degrees however prime 95 giving me around 72-77 degrees...

Theres a link in my sig to where HT is explained.
But in summary. If you are using Windows 7, turn HT on.

I have replied to this here:

Re:Hyper Threading Explained and discussed - Post #7

mikotan only reinforced my decision to turn HT off.

Again it will depend on what your use is.
I do a lot of editing and building so the more cores the better.
But when it comes to games, it does not really matter as much.

It comes down to -
1) If you do a lot of compiling and editing work with software that utilize mult-threads, then you will get more performance from HT on/Turbo on + lower clock.

2) if you do not use such software, turn HT off, turn Turbo on and go for a higher clock.

Also As I have stated, it wholly depends on the software it is being tested upon. Some software will utilize the multi-cores better than others.

thats pretty high with turbo off at 3.8ghz....
can you test with linx?
