Core i5 Overclocking and Feedback

[Cold Storm]

I know I have to crawl first before I can run

Is that the way you think via Fold@home? I don't think so!!

Can't believe you went thereconfused:

You see I cannot OC my folders like that because running them 24/7 requires more stability as oppose to 5-10 minutes for benching purposes

But yes I get the point Mr. Anime Freak

Good! Glad you know what I mean. Now.. we say by 21:00 you'll have that baby sitting at 4ghz?


Just think... Mine takes only 1.2625/1.258 in windows. to get stable at 4ghz.

Well, just collected an i5 750, EVGA P55 LE, and 2 x 2G Team extreem DDR3 2000.
And the choice of ram was based on it being cheap, and not much else being available locally.

Will be assembling from tomorrow.

Good job king wookie

It's not an issue getting it to 4Ghz and I will post a screenie by then

I will have to look at what is the lowest stable voltage.

Blah... the safe way...


Can't wait to see it happen man. I love my 750.. But, my ram is telling me to go 860.

Here's my first OC try at my 860

I can go higher but I'm waiting for my res to come in

Yeah, those 860's are hot ones.. well, I'll be seeing how they do in a few days myself

Hello guys,
my working machine, 24x7

 

[Cold Storm]

Looking nice Belitsky. How is it treating ya? think you can get some stuff out of it?

Thanks man, but my english not so good
Can you explain me what do you mean? I found a lot of meanings of "treating" in vocabulary.
It works just fine for me, cause my previous machine was Core 2 Duo 2.33 laptop, so now my apps opens much faster

 

[stevorob]

Gonna be reading through this thread, I just ordered a 750, an asus p7p55d pro, and some gskill dd3 2000 ripjaws.

Gonna be a big step from my Athon X2 lol

Ok. Can someone help with an idiot's guide to ocing an i5? I have oced before on my 775, but a clear step by step guide will be most helpful.

To me and others.

Thx.

Here is a great Dummy Guide that goes through i5/i7 socket 1156 information and settings.

But to make it simple just a couple things have changed when overclocking a i series chip.

CPU Multi = CPU Multi

BClck/CPU Frequency = CPU Speed For example: 200 (CPU Frequency) x 20 (CPU Multi) = 4000Mhz = 4 Ghz

QPI Frequency = 4.27 GTs for i5,s
QPI Multi = Lowest when overclocking

MCH Strap= Ram Multi (But most boards have direct RAM settings So I leave mine at Auto but you should check to see specific Motherboard settings for your set up.)

Vcore = Vcore (i5 750 no more than 1.4volts on air)

CPU VTT = CPU VTT (Uncore) Intel spec no more than 1.21 volts but I have seen people go over this when over clocking..... higher overclocks.... I have seen around 1.3/1.4 but again some people consider unsafe.

PCH = PCH: Mine is at 1.10 volts on a 3.6 over clock

DIMM= DIMM: no more ever than 1.65 volts!

CPU PLL =CPU PLL: Safe between 1.8/1.9

That's it in a quick nutshell but read the guide I posted it helped me a tone Good luck!!!

All good man.. Treating would be, in your case, how's it doing for you. But, the next sentence said it all.

all right, you got this..

• Now, you got the factor of "boot" and "eventual".
  1. Boot is the volts needed to "boot" up the computer.
  2. Eventual is the volts needed to keep the oc going..
  You know, the factor that most oc's need more volts to boot into windows, but vdroop would make it to where you need more via prime, or even less in some cases.. lol
  
  
• The "QPI" is just for hyper threading. Think of CSI (Common System Interface).. for 750's you can leave it at auto and you'll be fine. I had mine at 4.2 Gt/s..
  
  
• Most chips, boards, will do stock up to 3.4ghz. after that, some have seen to be before, you gotta start upping the volts..
  
  
• Vtt is form of FSB for this day and age.
  
  
• They say that the PCH is the volts that you should never go above 1.225, via intel. But, that's just the fact, I'm thinking, to make people not want to oc.. I could be wrong but I had to have 1.4 to get my system to be stable at 4.4ghz..
  
  
• Now, some do have this, but some don't. Mch Strap. That's a option that can get the ram stable. the higher that you take it, the better it will stabilize your ram.
  
  
• One thing never to do, go above 2v on the Pll volts... I've seen that with that volt, it can fry the cpu. Then again, the only factor I've seen it happen to was someone that was taking 15 other people's advice to his chip and just burned the chip and board...
  
  
• I wouldn't mess with the pwn volts.. There isn't any reason for that unless your going to want and see what the lowest volts you can do. I never messed with mine and I was able to keep 4ghz stable at 1.256.. Just a matter of the person pref..

Hope that can help.

damn you man.. I was typing as fast as I can... lol.. But, with tom's... that's all ways "dummy" proof in some since and more since to try and get people in there because they try and write stuff to get more "questions" then anything..

LOL Yes!!!! It didn't happen to me this time..... sorry to scoop you bud Lmao but the same thing happens to me all the time

All good man.

At least you answered one of the questions I was asking...... I was never sure what the QPI settings were all about. Now because of you I know thanks bud!!!

 

[Cold Storm]

No problem. I learned from a oc set up for a 860 chip... SO, for a while I thought myself it was a needed thing.. Some say it is for the 750's due to it being a term made from CSI, but some will say it's not.. I've all ways had it at 4.2 Gt/s just because I never seen a reason not to...


Also, if your antcy about getting to 4ghz... here sure fire settings.. If you can't do it on this... then the chip will need MORE something.. probably CPU volts


CPU v
Boot 1.4
Even 1.4

Vtt
Boot 1.4
Even 1.4

PCH
1.3

Pll,
1.8

QPI
4.2 GT/s

with memory at 2:10 via 1333.. everything set on memory as standard.


Also.. 1.65 is the safety volts for ram.. it's your baby blanket... But, you can go up to at lease 1.8v without frying the DRIMM... Just gotta make sure the ram can take it themselves Via. Memtest..


I would make sure to download Memtest86+ to make sure the ram can run at the higher clocks if needed...

When I was going for 4.6ghz, I made sure to run the Ram at the specs needed via this..


Bclck at the desired spot,
CPU Multi at the lowest it can go.

That way you know the board can handle it via every volts.. So it's just a matter of what is wrong... Most likely Memory Controller

Yeah if you do research on that subject you would be surprised on how much people are avoiding it like the plague! I am sure someone knows that answer for sure..... but know one seems to want to talk about it.
I think if you do talk about it Intel might swoop down in the night and steal your first born! LMAO

Anyway yeah that's what I have always had it set on too.... 4.27 GTs just because from what little I have read that seems to be right for the i5's. It seems that i7's need it is set too 4.28Gts at least that is what I have gathered..... but like I said I have no reason to back this up.

Thanks again!

Welcome. I might test that factor of if 4.8 does do anything... There is so many benches that say it does.. but after reading 2 reviews from Guru3d on Motherboards.. I really don't trust them at all.. Two different boards but same ss for the things... I'll download from them but that's it anymore..

nah no sticky... But thanks bro on the words.. Throw me a pm my phone's been buggy as hell the past week.. well since I got my new router.. Got a setting screwed up.
