TPU's Core i7 Overclocking and Feedback

[Fitseries3]

its not evga nope. i hate that board with a passion. i'd piss on one if i saw it.

ECS FTW cheap yet good

so what are you experimenting with Fit? some dual socket i7s? xD

Giga Ftw!

@ Paul nice OC!

So guys what does turning off the Hyperthreading do?

Does it help lower temps?
Does it allow you to overclock better?
Does it really affect preformance by not using 8 cores?

yes
yes
sometimes it does sometime it doesn't... sometimes turning it off is better for performance... all depends xD of what you might ask? well don't ask me!

Yes, yes, and it depends. For the most part 8 cores are never used. However, if you are using an app like WCG, the 8 cores are helpful.

Holy crap, Paulie - that's nice

@ Fit - I think you got some "classified" info

he always has some damn classified info

its not evga nope. i hate that board with a passion. i'd piss on one if i saw it.

is that because one of your best buddies has one "cough" RRR "cough"

yes
yes
depends on the application

I leave it enabled though.

Can't get the 4.8 yet, but this is not bad.....

Batch # please?

 

[t_ski]

The answer to the hyperthreading question is turn it off if you want to OC higher than 4.0-4.2 GHz, especially for running benches that need a higher overall CPU speed. Other than that, it doesn't really matter.

I'll get that for you this afternoon.

nope. that and the BR were both overhyped to death. im fucking sick of hearing about the damn board. im glad no one has tried to flaunt it here on tpu yet.

you can't deny it is pretty good nonetheless... but idk about expensive boards anyways lol

 

[Fitseries3]

whats good about it is most of the ones you see getting world records are hand picked. not all of them operate as well.

i mean think about it...

90% of them are on LN2 or phase. ppl that have that kinda stuff have been getting hand picked stuff for years. why wouldnt they have a hand picked mobo now?

Yeah,and the BR performance wise was near the bottom of the 5 i7 boards I've owned. Other than being the best looking i7 board, it did not deserve the hype.

Cosmetics and even the sexy name sadly appeal to some, I prefer to concentrate on stability, compatibility and value for money, if the board is fugly, i'll simply tape toilet paper to my case's side window so I can see it

I have to say my RE2 looks good and performs like a beast, with 9gb of ram it boots up to 4.6ghz no problem and to me that's a feat on air and will run 24/7 at 4.2ghz at 1.264v

So a final conceptual question about HyperThreading, does a higher overall clock speed w/o HT out weigh a slightly lower speed with HT on?

Basically does the benchmark/game benefit from using the virtual cores at 4Ghz over a 4.3Ghz w/only 4 cores?

I'm gonna do some research on this and see if the impact is evident. I'm assuming that you all bench with HT off as your runs are over 4.2.

I personnaly would turn off HT unless somehow gaming gets a benefit from it...

 

[Fitseries3]

if you have substantial cooling then you can leave HT on no matter what as temps and voltage wont matter.

remember though, turbo mode is only 1 core. i think alot of people forget this and think "my cpu is running 4.5ghz" when in reality, on the 920 its not. only 1 core is.

a true 4.5ghz would be achieved with turbo off and all 4 cores running the same multi

**this is just an example though.

not true turbo mode x22 is one core / single threaded apps, x21 is all cores /multi threaded apps. thats why if you turn all core off but one you will get a x22 multiplier but if you lock x21 and run a multi threaded app you will see all the core are using a x21

 

[Fitseries3]

no its not. doubt me if you want but ask around and you will see. 21x is ONE CORE ONLY.

 

[trt740]

no its not. doubt me if you want but ask around and you will see. 21x is ONE CORE ONLY.

sorry your wrong on this one, look in your bios under turbo mode it's even listed x22 x21 x21 x21. I know that after a certain number of multi threaded applications like 3 running at once all cores then will move to x20, but even that's has been under debate. Lock all your cores but one and you will see it use the x22 multiplier. Then turn on all 4 and it will default all 4 cores to x21. You get x22 for single threaded apps on one core, and x21 on dual threaded apps on all cores, x20 on all cores after that. http://www.maximumpc.com/article/fe...overclocking_guide_we_push_nehalem_its_limits

A little tool from uncleweb makes it very easy to verify the truth. Try it for yourself....
