TPU's Core i7 Overclocking and Feedback

[Binge]

Now I have installed vista and am now d/l drivers hehe I will be back l8a with screenies

Why does he multi change? I have F7 bios do I need to update to the latest to support D0?

The multi changes because of C-states. Make sure your CPU features are set correctly. I believe the F7 is a good bios but you always want to keep it as up to date as possible for maximum compatability.

I guess because of turbo aswell huh.

 

[Wetbehindtheears]

Yeah... If Turbo enabled then you'll get 21.....

x21 is not that bad though (unless benching)..

 

[grunt_408]

I am going to be firing it up later on. I will downclock my Ram and see what I can get out of the cpu for a start. I think with my setup I should be good for 4GHz.

 

[Wetbehindtheears]

Leave RAM on Auto to begin with ...

Edit: should have said... since you have a similar mobo and chip.. look at this first..

http://www.tweaktown.com/news/10827/gigabyte_shows_how_to_overclock_i7_920_cpu_to_4ghz/index.html

I got to 4GHZ and understood a lot more about this chip...

Why would x21 be bad for benching?

 

[grunt_408]

geez in that guide the dude went straight for 1.4volts no mucking around .

 

[Fitseries3]

i have yet to need 1.4v on my D0.... and im running it upwards of 4.6ghz with HT on.

 

[Binge]

Guides suck. Get your feet wet. You want to know what I had to go off of when the whole i7 thing started???

Believe it or not that's all you need to know.

 

[Fitseries3]

+1 binge.

if you look at the start of this thread i didnt really start showing anything until a week had past and me and dark had our setups from the 1st day it was launched.

i spent the time to get to know how it all correlates to learn what is needed to keep everything running happy.

I could have sworn that I was told (here or i7 Club or 1M SuperPi) to turn OFF x21 for SuperPi benchesi!

re giude... I ignored V settings as I was a bit worried about Max then adjusted accordingly.....

 

[grunt_408]

So far I have 3.2GHz on 1.27 Volts. I lol'd @Binges post above I dont think I will be needing 1.4volts either.
So far I have just played around in the bios I will keep doing so and reading through your post's that is all I will need to do you guys have done all of the legwork for me I just need to flip through your post's

That's complete bullsh*t super pi gets better scores if you turn HT off, not turbo.

TRUE! I saw on average about .3 seconds quicker with HT off. Super pi is single threaded app, you will most likely see faster runs if you run on two cores, maybe even faster on one core.

 

[grunt_408]

Ok guys calm down now

 

[Chicken Patty]

Ok guys calm down now

If I calm down more than what I am, i'll stop breathing no, just explained why, nobody is mad here

Turbo mode raise the clock of the most heavy loaded cores/threads, and reduce the clock of the other cores/threads that is not under heavy load, so it will increase performance for single thread applications (this is what Intel said).

I'm not clear how exactly turbo mode really work, and the x21 multi. So, I just got it off, and using the solid x20 multi.

That is also a false interpretation of what Intel spoke of. With newer motherboards that have the ability to override the CPU's ability to sense TDP and throttle the multiplier also rids the chip of the problem of losing the x21 multi on any given core. The only multi that can not be accessed is the x22 multi on the first core which can only be accessed when under the correct turbo conditions. This usually means no motherboard overrides etc.

Such is life... we'll repeat some subjects over and over again. The fun will really begin in this thread once the rebranded i7s are released. Their CPU structure is ENTIRELY DIFFERENT. New! Exciting!

Does anyone fool with the QPI PLL on their baotds when overclocking the Uncore. I am having a el of a time trying to run my Uncore at x18+ for benchmarks. I increase the DRAM from 1.660V to 1.720V. The QPi gos from 1.355V in BIOS to 1.40V in BIOS. I raise the Vcore from 1.36725 to 1.3825V. Now for this I am keeping my BCLK at 200 my mulit at x21, so 4.2 ghz, ram is 800 mhz at 7-7-7-16. Now the 1st settings are all nice and stable in Linx and Prime, but the minute I raise Uncore from the usual x18 (which I run it on 24/7 memory is on x8) to say x19 or x20 I can not boot into Windows I might post here and there but no boot up into win 7. Any thing I am missing when trying to bump up the Uncore. I just want to see the impact it has on Vantage, leaving all the settings the same except the Uncore going close to 3.8 or 4.0, I have it at 3.6 usually.

My mistake meant HT .... been a long week that's getting longer!!

 

[mastrdrver]

Jake try RTL. It helped setting the higher unCores for my on my P6T6 easier and helped bring down the volts. On Vantage, I've yet to see an improvement because of unCore speeds. QPI though will drive the scores up quickly though. Just got to figure out how to get past 4ghz on QPI.

 

[mastrdrver]

LLC disabled but c-state c7 and c1e enabled.

Still needs work as it can go lower, but got to get some sleep.

 

[mudkip]

Bought 2 OCZ vertex 30GB and putted them in raid0 with ICH10R

Benchmarks:

hereby I command every i7 owner to buy SSD's. Everythings runs so much smoother now.

imo, 4GHz Uncore Frequency needs QPI/Vtt ~1.5-1.57volts
