TPU's Core i7 Overclocking and Feedback

[Fitseries3]

98% of TPU needs less than 750watts

Question, does anybody know what the uncore frequency is by default??? Or how can you find that out?

Also what is uncore on the core i7's, can't find an answer anywhere.

 

[Binge]

Uncore is every other function of the i7 other than the cores. The default frequency is directly related to your memory speeds. I hope this helps

Thanks, I get what it is now, so it is related to the Memory controller as well. I saw a vid about some guy explaining how to overclock it and stuff he was saying there is usually not any increase and its better to leave it alone. But I rather set it up manually if I knew what the default was, wouldn't leaving it on auto allow for it to adjust automatically?

Also, there are two voltages that should be kept within .05v of each other, I believe one is DRAM and the other is??

 

[Binge]

DRAM and QPI/DRAM voltage

 

[Chicken Patty]

DRAM and QPI/DRAM voltage

got it.

QPI voltage is basically voltage for the IMC right?

 

[Binge]

Bingo! QPI is short for Quick Pass Interface and that is the memory controller.

 

[Fitseries3]

you read it all wrong.

vcore is whatever you need.

qpi/dram is whatever you need to drive the bclk

Vdram can be up to .5 - .7v higher that qpi/dram(qpi/dram x 1.5 = ~Vdram)

got it, i wont be playing with them now, but eventually I might come across the point where I have to and I just wanted to have this straight.

Na Cp just waiting for Phenom 2 940 to hit new egg i done what i can with this cpu . Pick up a sec. 4870 for your new rig and we meet up in the 20,000+ point land out at 3mark . Be safe have a merry X-mas CP i get out your guys thread .

Yeah, I alrady spoke with my local store and I will take them my board on Saturday to replace it, still under the 3 month warranty with them

This way when the Phenom II comes out, I can grab one and still have my AMD rig running.

However, I do need a 2nd 4870 bad bro hehe, hopefully soon, and come on dude, stick around, this thread is pretty darn right interesting, lots of stuff to read and learn about the core i7's even if you dont own or won't own one, its always good to know

Plus I never saw myself sporting intel hardware, but here I am, can't be happier to be honest. Still love AMD though

came across that the other day, interesting stuff.

CPU's are a crazy piece of work!!!

my spec sheet on my pc power 860 reads max output is 1138watts

That is freaking awesome. I will keep that in mind for my next build
this summer. With me being poor right now and, in a big hurry to
get back on track before the boys get home for the holidays, i
went with the CHEAP good PSU. Through nextag i found an Antec
850 for $119.00 after $100 discount plus 20% off. Should be here
in two days.

Also what is uncore on the core i7's, can't find an answer anywhere.

In CPU-Z the uncore is shown as the NB frequency. I have had
best luck when setting uncore to equal or a little higher then
QPI link freq.

P.S. i just want to say thanks guys. As usual this forum ROCKS.
This is not just a great place for info but damn, you guys are
just great.

i need more than 750w

Thats not a bad deal on a PSU, but bro if you can get a pc power and cooling, do it, you wont regret it, like I said its my next step.

Thanks for the uncore tip, and thanks for the compliment, this forum is the s**t. I joined xs and honestly I dont log on there no more, just not the same.

BTW, you mean setting the multi equal or a bit higher than the QPI, or the actualy clock it runs at equal or higher than the QPI.

I know with AMD your HT (QPI for intel) has to be equal or less than the NB frequency or you have stability issues. Is it the same for the i7's?

The actual clock freq..

Indeed
The QPI Link freq. should be equal or less then the Uncore freq., at least
for me it worked best that way 'only slightly higher uncore, not too much'.

so it basically works the same as AMD then, figured as they both have IMC's!!

Thanks dude!

Here's one guys understanding of the i7.

http://www.xtremesystems.org/forums/showpost.php?p=3495431&postcount=876

If you understand this then please explain it to the rest of us!

Here's one quote about the relationship between DRAM, Uncore and QPI..

DRAM speed must be in a 1:2 ratio or less to Uncore speed which in turn must be in 1:1 or less ratio to QPI link speed (8:9 Uncore to QPI or lower is preferred as the more you approach 1:1 the more unstable the system becomes).

just the quote drove me hehe

 

[kid41212003]

DRAM multiplier is 8, Uncore multiplier is 16, QPI Link multiplier is 36.

EDIT: I'm confused myself.

The QPI Link multiplier in my bios doesn't have anything lower than 36...

 

[Fitseries3]

when my net comes back ill explain it all in english so you guys can get a better idea.

 

[LiveOrDie]

hi guys i need your help when i overclock my i7 to 3ghz i lose 2gb of ram and it only picks up 4gb in the bios, is there a setting to change?

I've never heard of that problem and I've been trolling all over the place learning about i7 and helping people OC. A problem with your board? I'd contact the manufacturer.
