Help with i7 870 please

[vychytraly]

Hi hou, i would like to overclock this little i7 guy, but im not sure if im sure how to do it.
Please just tell me if im right, if i do it correctly.

I dont know how much could i overclock it, intel dh57dd motherboard have got just 4 pin supply for cpu. But i will try.

I wont change anything here.

I wont change anything here.

Here will I raise clock frequency to 200

Here will i turn of turboboost. When wil I reach stable OC I will turn it on again. So when FSB would be at 200 I must decrease maximum non turbo ratio from 22 to eg. 16 and continually increase it to 17, 18 ,19... until I will reach maximum stable OC, the temperatures will say me (I think that I should oc to 80 celsius degrees).

But should I raise CPU Voltage?

I wont change anything, Am I right?

And here should i let it be on automatic or should i change it to manual and decrease RAM multiplier to 8? (I can choose only 2 4 6 8 10 12)

I hope its all, if not please tell me

Please sorry my english and thank you very much in advance for your help

This looks to be a lower end intel board. I would not trust it for decent OCing but if you insist we can help you as much as possible BUT remember we are no responsible if it blows up.

First you want to check to see if you are allowed to change the turbo multi if so find out what the max multi you can set it would be. Looks like it will go to 27 but need to check first hand. Also it looks like it has VERY limited power control so do not expect much out of this board.

I thought that this motherboard can stop me by its limits and it wont allow me to OC more than it can stand. It is an Intel Mobo but it isnt as bad as it looks, its cost was something about 100€. Do you really think it could blow up?

Going to check Turbo multi

Going to check Turbo multi

Yes if its a cheap low power phase is most certainly can.

 

[vychytraly]

So Turbo boost can be just disabled or enabled, I think that means it will stay disabled forever because the multis would be so high if will I OC it...

 

[vychytraly]

and how could I figure out if the power phase is cheap or not ? )

 

[brandonwh64]

By looking here it looks to be something like a 3+1 or 4+1 phase which is quite low for OCing.

I would suggest getting a decent P55 board

but in Slovakia the 1156 socket motherboards are no longer in sale I found this one used for 30€

Gigabyte GA-P55M-UD2 - LGA1156

 

[vychytraly]

but how much could i OC on this intel mobo? could I maybe to 3.5 GHz? or how much could it stand and supply?

That board is alot better than the intel you have

*EDIT*

You can try to set multi to 21 and BCLK to 167 leave voltage on auto.

"You must walk before you run" -Go small baby steps with bclk/fsb/host clock. Also you current board won't allow QPI clock adjustments. Max you will probly get is ~ 170.

PS:
Current goal IMO: 24x166 with a +75mV on cpu core voltage, dropping ram multi one notch to 1333.

 

[vychytraly]

Yes I know how to set it up to 3,5 GHz, I just wanted to know if you think that intel mobo could stand it

But thank you very much

But if there is a really big risk of blowing up the motherboard i will not overclock it. If the mobo blows up by overclocking could it kill another components?

I doubt.

YMMV on that, its according on how good of VRM's intel used

 

[vychytraly]

I cant set multiplier to 24, max is 22 for non turbo and what is qpi clock adjustment? and why should i drop rams to 1333?

 

[brandonwh64]

When you OC the Bclk the ram speeds go up as well so you need to set to lowest for ocing CPU

 

[vychytraly]

I thought i should set their multiplier as close to their original frequency as possible.
Their original frequency is 1600 so why should i decrease it to 1333?

 

[JrRacinFan]

QPI adjustments, you can ignore my mention of it but when going to a high bclk (read: ~ 180-205) this may need a notch or 2 down as it will play a toll in IMC instability. Ram: since you don't have IMC/QPI/VTT voltage adjustments that may play an effect on IMC instability as well.

I really dont know sorry but thank you for your reply

Honestly if you do not know what we are talking about then you should not even attempt to overclock.

integrated memory controller (IMC)

 

[JrRacinFan]

Integrated memory controller.
Oh btw, QPI= Quickpath Interconnect.

Before you ask any more questions please read the guide below. I know its for X58 but the architecture is similar

hmmm Overclocking AMD black edition processor which belongs to friend of mine was far easier
I didnt even thought that overclocking processor without unlocked multiplier is as difficult. Going to read, sorry for silly questions

That guide can also be interchanged (for the most part) with s1156 just for general guidance purposes. Thank you B for posting that.

EDIT:

Yeah they are a little easier but in a way this is similar if you overclocked a non black edition before.

PS: The worst problem with this world, not asking those "silly" questions. There's only silly answers.

this table is superb

Acceptable performance goals for 24/7 use & Benching (45nm Bloomfield):

24/7: stock CPU, high memory multi- BCLK 133, CPU Multi x21, Memory Multi x12, Uncore Multi x24-x27, QPI AUTO. This will require little to no core voltage change, but you will most likely have to increase the QPI(vtt) voltage, and the memory multiplier is high so uncore will also be very high for your CPU. This is memory overclocking for a target of 1596MHz so your computer will feel a little more snappy, but nothing quite like what a core OC would do.

24/7: Mid range CPU and medium/high memory multi- BCLK 166, CPU Multi x21, Memory Multi x10, Uncore Multi x20-x23, QPI AUTO. Less stress on the QPI(vtt) and uncore. May be easier/produce less heat than the settings above. Most D0 stepping can achieve this using stock VCore, but keep in mind not ALL can. Target CPU 3.48GHz, Target memory 1660MHz.

24/7: The "magic" BCLK OC- BCLK 200, CPU Multi x13-x21, Memory Multi x8, Uncore Multi x16-x19, QPI AUTO. This is my favorite setting for BCLK because it makes for an EASY 1600MHz ram OC, and you can clock your CPU from below stock to 4.2GHz. You will have to tune this but it is so much easier on the memory OC. Some chips handle 200 BCLK like they were made for it while others (mainly seen in the first steppings for x58 i7s) fail miserably and require LOADS of voltage. Raising the BCLK is preffered for memory overclocking because it allows you to keep low multipliers which is better for stability!

I think it is fully interchargeable with i7 870 or not?

But weird is that my default uncore multiplier is 10. Should it be 24?

There is always QPI on auto, so coudl it be a problem if i cant change it?

Do you allow me to try "24/7: Mid range CPU" setting?

If I understood right I shouldnt care about QPI in this case. And maybe I will need to increase CPU Voltage a bit. (how much? +25mV?)

And should I increase Uncore multiplier to 20 in this case? Why is default 10?

I hope that these questions are not as silly as the questions before

Thank you very much for your time
