Core i7 920 rev D0 stepping 5 :)

As you know most peeps get higher OC's with HT off, do you think its better to have stable OC running at lower speed with HT on or higher speeds with HT off ? This has been on my mind for a while as i have read that having HT on only improves performance by about 10%

That really depends on if you're using HT I think.

Well as i'm only mainly into gaming and listening to music...no video editing ....guess HT off would be best option for me

I'm in process to figure this out, will have to run some benchmark (PCMark Vantage, everest, etc) to compare 4.40Ghz with HT enable vs. 4.50Ghz with HT disable to see which one I would pick to run 24/7. Other than Photoshop CS4 I have not seen any game or apps that can fully utilized all 4 cores left alone 8 threads, I use my machine for photo/video editing, gaming, movie and music playing. Keep in mine that clock for clock you would see almost 10'C reduction with HT disable, if yours is approaching 90'C underload with HT enable, you probably want to disable it, or go easy on the overclock.

Damn I don't know what to do guys, I have these 2 to choose from:
3849A823
3847A839

Seems both weeks clock very good, there are good 47's and there are even better 47's... and there are good 49's and even better 49's... I don't think it would matter right?
choices choices

Ah thank you, that sounds like great plan. Meaby start new thread for this as i'm sure many peeps will be interested Top man

I would be atleast as my cpu need over 0.1 MORE for HT at same speed (4,2Ghz) and hitting over 80c with my WC.
While in HT off, 4,2 i get about 67-68c on highest core in Linx with 1.36.

[mk-ultra]

not really a 920 d0...but close
i still need to tweak some stuff but so far so good
max blck for the moment...hopefully i can sqeeze out a few mhz more

real vcore(dmm): 1.237/load - 1.220/idle
turbo -off
ht - on
linpack max temps are shown in realtemp

4.2ghz @ 1 hour Prime95 small FFTs. Not too shaby.

[Zucker2k]

That's impressive. Water?

Edit: NVM.

[drnip]

Air. Lots of it!

[Zucker2k]

That's one nice looking "air" machine you got there.

Here's mine so far... waiting on an XSPC RX 360 Rad. to hold the temps down then I'll shoot for more.

[drnip]

Nice, very nice. Don't know what mine will do for an hour at 4.5ghz prime style as temps will get a little hot on me. I am sure it would be right in line with yours.

Nah, I'm sure yours will be better since you only need 1.200v for 4.2Ghz with HT. I bet with proper cooling you can prime at 4.5Ghz with HT on at max 1.35v. Nice chip you got there.

Edit: The only potential problem you'll ran into is whether your board will allow stressing at a high bclk.

True that. I have made a couple attempts at 4.5ghz but BSOD's. Prolly need some more fine tuning. What mobo you using? What VTT?

Asus P6T (vanilla). Vtt is 1.35v.

[drnip]

Thanks. I will give it another crack at it soon as I would like to get 4.5ghz stable well at least stable for a hour just to say I did it.

[Zucker2k]

Goodluck. If you haven't already, bump pcie frequency a little - 102 -104, ioh to 1.18-1.20.

4.2ghz with HT on stock voltage Prime stable on air? Absolutely outstanding i would say. Really golden chip. I can't imagine what this chip will do on water.

Yeap that is about spot on to what I had. Thinking I need a little more Vcore. Will be working on it this week.

Here is my new i7 920 D0 Batch:3847A821

[The Water Dog]

I post some pics. of my tomorrow, since i got only my stock cooler. But im picking up a Noctua hold-down plate to 1366.
But what VTT-volt is "okey"?

Lots of nice oc here now

[roller11]

Just got my rig dialed in, a Do w/ Classified 760
tuniq tower 120, air

Personal record so far:

Nice clocks roller11 ... are you still using that D0 B027 which you were planning to RMA back to intel or is this another D0?

No offense but I think you must mean "3847A821" as there is no 3874 yet.
