i7 920 @ 4.4 ghz

bulldog147 · 25 Sep 2010 at 22:16

The temperature was crazy up to 92C with Noctua D14 with 2 x 1300rpm fans for 4.4 ghz.

Maybe I try turn vcore one notch down abit or shall I put qpi a notch down ?

I had now managed to put vcore down to 1.40v at bios and qpi at 1.32v as the temperature much better at around 84C.

Is it prime95 stable or are you just benching for the lulz?

Turn hyperthreading off

.

Ok I try that, doing 4.5Ghz with HT off with prime95 (10 minutes) as max temp so far is around 79C with bios vcore 1.40v and qpi 1.32v

screw that, get HT back on.

otherwise you may as well have a q6600

was the 4.4GHz stable?

it was running 4.4Ghz for 20 mins on prime95 with HT enabled (on) but temperature pretty too high at around 88C! But the fans is only running at 1300rpm with a push pull. I havent try 2 x viper fans yet! So, I cannot confirmed if it was stable unless I had to run prime95 for 12 hours!

rjk · 26 Sep 2010 at 00:48

that temp is ok mate
not brilliant but its not going to be.
as long as its hovering below 90 then you shoudl be ok.
does it work with the vcore down a bit? i would imagin your cpu may be able to hit 4.4 at around 1.375

get the vipers on there to cool it off a bit.

also, if you are going for top end stability runs, which you are likely to not use 24/7 then it may be worth getting the side off your case and aiming a few spare fans at your motherboard

especially places like the NB and mosfets where heat builds up and could cause problems.

good to see you back on the clocking train bulldog!

Lol, defeats the point of an i7.

This.

Also why are you using easytune bulldog? BIOS overclocking will yield far better results than moving sliders up and down, anyone can do that.

while i agree 100% keeping HT on, does turning it off get better fps in games i was reading or is rubbish?

domthecondom · 27 Sep 2010 at 09:12

get on the watercooling!

HT will not benefit games and as turning it off will usually help keep temps down (so you can have a higher OC) so in theory turning it off would help get higher frame rates...but why would you buy an I7 for games??

think you will find a silly number of people got a i7 for gaming. What is more stupid would have been paying £140 for a E8400 vs £200 i7 when your doing a new build

what's wrong with a i7 for gaming?

Actually I disagree. Unless i7 overclocking has changed things, I found that with my q9650, I could tweak it in windows to 4.9Ghz to do benchmarks etc but could never get it to boot at that speed. Always had to boot at 4.65Ghz and adjust upwards from there.

Even putting the working settings in the bios never worked.

So I find if going for points/records you can eek a little bit more out of your cpu by using software.

Steady on guys, no need for that!

Turning hyperthreading off will get him a higher clockspeed which will benifit some benchmarks. As the OP is not clear as to the extent of his uses of overclocking, only his obsession with temps then disabling hyperthreading will lower temps (as shown). The stress on the CPU will also be less and will yield a higher clockspeed. A higher clockspeed on four cores will benefit him in applications that do not use the theoretical 8 cores.

If ultimate overclocking is what he is aiming for then my suggestion remains valid tbh. Personally I don't turn hyperthreading off as my uses differ from the OP.

Using Easytune in wondows WILL yield higher overclocks than the BIOS. While these overclocks have the potential not to be as stable as BIOS overclocking (due to ommission of the stresses of the boot process), overclocking in windows can get you the golden CPU-z screenie that otherwise would not be possible.

You guys should know this!

rjk · 27 Sep 2010 at 14:28

we do know this, hence our advice.

im sorry, i totally understand and appreciate the arguments for and against HT

but i fail to see why anyone would diasable such a major feature/capabilty of their system.

its like having two graphics cards and disabling SLI/crossfire

each to their own, but i just find it totally bizzare

Agreed. Unless of course you are folding

Although you can leave SLI enabled nowadays.

i7 with HT on: "Today I'm going walk normally using both legs."

i7 with HT off: "Today I'm going to walk using my hands and look ridiculous"

If people want high FPS in games an i5 760 (no HT) or a Phenom II X4 would be more appropriate.

bulldog147 · 27 Sep 2010 at 14:44

I only do both HT off and HT on for a quick benchmark, but for 24 hours gaming, I will always use HT on! As for easytune, I only checking what the boot value voltages target is, I always change the bios setting in the bios area, not the easytune!

Hope that clear! I managed to get 4.6Ghz with HT off, but couldn't get it stable with HT on, knowing the temperature will a hell lots hotter! Need a very good phase change, or custom water cooling!

I am now happy and stick with my stable 4.4Ghz on my i7 cores with HT enabled with max temp of 83C with two viper fans as push pull. Couldn't get further 4.5+Ghz because of too hot.

...or more logically:

i7 with HT on: "Today I'm going to drive my (very fast) juggernaut."

i7 with HT off: "Today I'm going to drive my ferrari."

Akin to comparing engine torque to Bhp. What suits one might not suit another. I'd love to see you walking on your hands Nath though, quicker than you walk on your feet!

I appreciate there are better chips for gaming (assuming you want the fastest clock per clock and have no need for the extra lane of memory) but that isn't the question at hand. Why turn HT off? It allows faster clockspeeds at lower temps! Sure it's not using the i7 to it's full potential with all the features but it all comes down to what you want from a CPU, speed or power - personally I like both as suicide sceenies are not for me but I see no harm in advising others how to get what they are looking for?
