I7 overclock help

[Alle22]

hi i have just overclocked to 4GHz with 1.35625 volts question is whether it is too large for a D0 or is it normal? i have even tried 1.3875 and without bsod.Qpi: one is now at 2.8 ghz you should increase or decrease the QPI: one for better stability? Have max temp 75 degrees sounds like a lot? I tried over 4GHZ but then it comes bsod. Thanking for the reply

It depends on the individual chip. Some only need vcore in the 1.1-1.2v range to hit 4.0ghz. Others, like yours (and mine BTW) need a higher voltage to hit the same clocks.

So no, it's not too large for a D0 and yes it's pretty normal.

should increase or decrease the QPI: one for better stability?

Increase.

Blue screens when overclocking are often the result of incorrect RAM settings as much as they are voltage related.

Have max temp 75 degrees sounds like a lot?

Not when stress testing.

First off if you're going to try to overclock to 4gig you need to get off the "Auto" everything and start "manually" setting voltage values. That's what "true" overclocking is. Since you're going for 4gig you are "truely" overclocking the processor!!! Here's a few tips.....

- DRAM voltage should not be set to "Auto" it should be manually set to 1.640.
- 1.3875 is too high a voltage for the chip
- QPI/Vtt needs to be manually set to at least 1.2500, most will say 1.315

There are other things you can do as well but those are starting points. Also do you know what BIOS you have? The screens you show look a little dated. If you look at my system specs you'd see I have a Gigabyte board as well, though different model.

I get the feeling you don't have a full grasp of overclocking - I say that due to the fact that you have a few voltage setting that should be manually set as opposed to being left on Auto.

With that may I suggest a some reading..... 3 Step Guide To Overclock Your Core i3, i5, or i7 – Updated! | Overclockers

I would also suggest you visit TweakTown's GIGABYTE forum - They have excellent advice on overclocking with "Gigabyte" boards

Good luck

If his memory is speced @ 1.5V at 1066 MHz then he should not set it to 1.640V - there is no reason to increase that. The screen indicates it is being set to a SPD profile, which is OK.

The QPI doesn't need to be as high as 1.25. It may be stable at less - that takes some experimentation, as does the CPU voltage.

Since overclocking is NOT an exact science our opinions may vary, however I do provide valid evidence to what I suggest in the links I post, and personal experience with a Gigabyte motherboard having a 1366 chipset using a core i7-900 series Bloomfield processor (i7-950 in my case). The OP has a similiar system to mine. Also I note you have an i5 system so your requirements are different from ours.

BTW I'm only overclocked to 3.5gig and I have to run my QPI to 1.25 just to be prime95 satable. On and I think I said the QPI needs to be somewhere between 1.250 & 1.315

Anyway I say again.... If he's going to clock that high (4gig) those voltages need to be manually set and since he's pushing the limits of the processor those volatage need to be that high.

Yes there's always exceptions to the rule, and we should always try lower volts first for temps sake, but if you start getting BSOD blah blah blah 124 codes - your QPI is too low (reading and personal experience).

Also look at any overlocked i7-900 series chip pushing 4gig and you'll see QPI volts around 1.3.

As for his memory I'll conceed his memory Corsair XMS3 DDR3 1333MHz 6GB CL9 only recommends 1.5volts - XMS3 whereas my Corsair memory (TR3X3G1600C8D) - Dominator® recommends 1.65volts! So yeah, his isn't required to be run as high as mine.

However he still needs to get off the auto voltage everything if he's going near 4gig!!!

My two cents.

This.
Hell, I had to pump 1.55 volts through my i5-2500k to hit 5Ghz, but took it back down to 4.5Ghz.
After some playing, I got the system stable at 4.5Ghz with 1.36volts whereas the auto voltage hat it up at 1.45V!

My two cents.

The memory voltage requirements are *not* different. There is n reason to increase it as you suggested since the memory isn't being overclocked. The MB is setting the memory voltage to that in the SPD, which comes directly from the memory and hence the manufacturer.

Yes, auto on everything isn't the way at that clock. And processor amongst the same model vary quite a bit. For my i5, I didn't have to change my qpi/vtt until I get past 3.94 GHz, and even then very little. My point is there is a knee there, and isn't best just to set everything high, then work down, but rather to pick a reasonable overclock, tune it, then slowly work up, adjusting one thing at a time, depending on the failure mode.

Both of these are valid ways to overclock...

Actually there IS a reason to pump the memory voltages if

1- the memory manufacturer requires it - mine does.
2- you run it past it's rated speed - depends on your overclock.

Corsair guarantees that my memory will run at a rated guaranteed speed of 1600MHz for normal usage with 1.65volts, not 1.5volts!

Now.... does my memory have to be run at 1.65volts..... no..... it can be run at 1.5 volts..... but that it won't run at 1600MHZ!!!! Which is what my memory's rated speed is

Bottom line some performance memory does have higher voltage requirements. Look at the specs on them. I didn't just make this up.

Does the OP have performance memory....no. Did I conceed this fact... yes.

And I'll say again, an i5 system is diffrent from an i7-900 series system - triple channel vs dual channel memory for one.

Thanks.

I am sorry if I repeated about the memory. but wasn't talking about your memory and I didn't say there aren't situations where you would want to increase the memory voltage. I specifically said there was no reason for the OP to increase his memory voltage as suggested since it was running at its rated voltage based on the memory's SPD information.

Sure i5 is different than i7, but from what I have seen that is a pretty high qpi for that voltage, Not that I have much experience doing this, but the approach that works for me has been to go as high as I stably can only increasing Vcore, then incremental clock steps upward beyond that. That way you can get a better handle of what voltage you need to increase (based on the type of BSOD for instance). If you start out with all high, then it becomes more tedious lowering thE voltages to just what you nee as there are more than one interdependent voltages to vary.

I'll agree to that point.

BTW the apporach I've taken is to run as low as I can with QPI/Vtt and V-Core voltage at a givin clock speed, than increase as needed for stability. Trying to find that temperature sweetspot vs stability

Peace

this is the Template from one of the Guys over at Tweaktown/Gigabyte wazza300

Good Quick guide if that is what you are after.

http://i31.tinypic.com/rs6gwn.jpg <=3.8ghz + 4.2ghz overclock template

also has the BSOD codes at the Top, so you know what to do when you see one of them. there is another good guide here.

Core i7 Overclocking Guide For Beginners

just for the sake of it.. im running a i7 D0. on a Gigabyte UD5
1.212v Vcore
QPI 1.275 since i have 12GB ;/
Ram @ 1.5v
28hrs Prime Stable.
4.2GHz HT + Turbo max temp 72c on a H50.. good enuff for me. Room temp in 23c

just takes time. and Remember to Run Prime95 or OCCT or 20 runs of Linux/IBT and watch those temps. id say a good spot would be 75c Max on the hottest core. anything over you should change the airflow or get a Better CPU Cooler, something i can't fit in my case. The NH D14 ;/

+1 on the start Low go high technique


What the guys here have said so far should give you a good idea on what you should do.

good luck.

 

[sygnus21]

Wazza is pretty good. I got a few tips from him as well as Lsdmasap. Lots of good info there (TweakTown's GIGABYTE forum). If you have a Gigabyte board that's the place to go.

Thanks DaGoon

On a side note, I'm not much on water cooling but I just may reconsider purchasing an H50/H70. Though I love my CPU cooler, it doesn't really handle high overclocks well. It's good for med range OC's, but going near 4gig the temps get a little too high.

I'm currently running at 3.5 with my i7-950 and avarage 74c with prime95 load.

 

[Alle22]

thanks guys for helping i will try to do some manuel setting instead for auto next week, why next week? cus i have holiday then I say what I did to overclock.

just going to throw this in the mix, since you are thinking about the Corsair H50, H70 or the new H60.

Yeah..... I said I "might" reconsider but..... and I worry about noise with regards to a push pull setup. Right now my system is really really quiet with the setup I currently have so.....

The other thing is if I did go with something like that, I'd have to go with the established guys as I'm kind of untrusting with having water in my system anyway. Hate to try some new guy who says "sorry, we'll get it right on the next revision"

And before I get beat up..... I've used Antec cases for years until moving to my current Cooler Master HAF X case. I've also used and still use their power supplies - see system specs

Thanks for the suggestions though.
