TPU's Core i7 Overclocking and Feedback

[mastrdrver]

I know what the reason is - QPI Link speed. If thats high then the CPU needs way more voltage.

Is that saying a bad memory controller on the CPU or Board?

Keep uncore speed below QPI speed and you will need less vvt. The closer QPI gets to 4Ghz the more vvt you will need even if uncore is below QPI.

Run uncore and/or ram higher, the more vcore you will need for the same core speed.

wtf is the problem here....

clock speed is wayy too low

 

[Fitseries3]

its a flaw in cpuz.

I was being sarcastic I'm sure you know. Hmmm, what would cause a flaw like that FIT? Wouldn't it happen to most people?

 

[Fitseries3]

no... only happens when you use SetFSB

 

[Chicken Patty]

no... only happens when you use SetFSB

ohh, weird. I never used that thing, couldn't get the hang of it.

 

[PaulieG]

I hate setfsb. Tried it once and had all kinds of issues. Nothing but bios overclocking for me.

 

[mastrdrver]

It's i7s super badass power saving mode!.........featuring extra vcore.

I usually set a stable high overclock in the BIOS and save the profile. Boot with it and tweak from there to go higher for benching. That works the best for me.

 

[Lionheart]

Damn man, wish I had a overclock like that 4 cores at 14GHZ sounds pretty damn sweet!

PS I know thats fake, but looking at it looks really nice!

 

[Fitseries3]

not technically fake.

it wasnt photoshopped.

just a flaw in cpuz when using setfsb.

Oh ok.

What do you usually have it at, 4GHZ im guessing

Run uncore and/or ram higher, the more vcore you will need for the same core speed.

Uncore is already like 200 to 400MHz below, only ram is "only" at 1520Mhz

With them on i needed less IOH Voltage and CPU Voltage

edited seems i found my new 4.2GHz settings

 

[FilipM]

So you eneabled Speedstep and C1E support ... i'll give it a go!

 

[SystemViper]

Fitz, your are the zen master of tech, love the way you provide insight

 

[Fitseries3]

Fitz, your are the zen master of tech, love the way you provide insight

you never had that problem?

the reason ppl dont like setfsb is because you have to know which clock gen to use.

on everyones mobo there is a clock generator IC.

locate it and it will have an ID number/letter combo.

find the corresponding number/letter combo in the drop down menu in setfsb and then you can use it to OC the board properly.

if you dont choose the right clock gen from the list you'll have major problems. mobo will most likely lock up first try. it wont kill the cpu or anything but you will make it freeze.

a quick google search can often tell you which clock gen your board uses.

with i7s there is a big in cpuz that causes the multi to jump when using setfsb.

most of the time nothing happens... some times you get a weird cpuz reading and 1 time out of 100 you lock up the machine. no big deal really.

hope that helps.

tried 4ghz but couldt get it stable enough

so i do a 3.8 atm

remember this is a CO, but still, i find it a tad hot at idle, using the dark knight atm, should be getting the thermalright ifx14 next week http://www.thermalright.com/new_a_p...intel_bp/product_cpu_cooler_ifx-14-intel.html

but should i do anything else? i have disabled all speed step things, C1E EIST and what not

using the MSI X58M not the best, but its okay for temp use

 

[Binge]

33-40C is normal idle temps for an OCed 920, just to be clear. Even D0s. C0s are funny. Some can't get 4.0GHz no matter what you try.

 

[(FIH) The Don]

well i can do 4ghz, but when i start messing with the memory timings and stuff it goes bananas, and yes i know its not the best memory,

+ it should be one of the best CO's in the world, or from the best batch

I had one of the best C0s in the world, and trust me 4.0 was like falling off of a log. If you're putting in bad subtimings I suggest you stop tightening the ram and enjoy what you've got OR you could just buy my DomGTs/i7920 D0

 

[(FIH) The Don]

ROFL i dont wanna spend more money on hw this month or 2,

but i can have it stable at 4020mhz, without messing with the memory, think its running at 1180 or similar.

but the temps was like 81c

 

[Binge]

Get a Corsair H50 or a Noctua NH-D14

 

[Chicken Patty]

Either your memory is not that grey or the IMC on the CPU is not the best. Relax your RAM and enjoy it dude
