TPU's Core i7 Overclocking and Feedback

[Conflict0s]

I tryed what you said by dropping my multi and what not, She didn't boot. Does this mean it is not possible for me to get a good clock on this chip? or will it just take alot more tweeking? (not that i wasn't going to do more tweeking anyways)

EDIT: I tryed 160 x20 with everything on AUTO and it booted And it looks to be running voltages of 1.264
And don't worrie, i am far from giving up on this.

Tweaking = success

Not only does Tweaking = success, but it's how your learn and get those speeds that you are looking for.,

The ability to Tweak is how you get from finishing in the middle of the pack to seeing the leaders. Cash, advice, effort, and luck can only take you so far.

Tweaking is what gets you the rest of the way....

Ok cool It is hard getting my head around all the different meanings to what different settings do in the BIOS. No doubt I will figure it out with practice and advice. Thanks for the advice so far guys, I think I am going to head off to bed now and have another go tomorrow.

For your sake and jake's QPI voltage is labeled as CPU VTT in some bios.

In my BIOS I have an option for CPU VTT and another for QPI/PCIE PLL. These are not related, correct?

 

[Binge]

Correct.

 

[t_ski]

What is a common NB voltage for 200 bclk?

 

[Binge]

IOH = North Bridge
ICH = South Bridge

In case you were wondering what those voltages were in my bios. Thanks Fit for reminding me which is which xD.

I don't know exactly what you can tweak in your bios. You can actually keep them at nominal (stock) unless you're getting unexpected hardware error blue-screens.

CPU VTT Voltage (default: 1.1V (+0mV in BIOS) Intel's max 1.35 (+250mV)
What it does:

VTT connects the cores with the memory. Raising VTT helps keep a system stable at higher QPI rate. Since QPI is calculated from bclk: the higher the bclk the more VTT voltage you will need. VTT is also called "QPI/DRAM Core" on other motherboards,


Prevent CPU damage: VTT voltage must be within 0.5V of VDimm. Vdimm can fluctuate by as much as 0.05V from settings so you may want VTT within 0.45V of VDimm for that extra margin of safety. Example: if Vdimm is 1.65V, then VTT must be at least 1.20V.

When to raise CPU VTT Voltage:

* BSOD 124 "general hardware failure"
* LinX errors happen only after 10 min or more
* LinX hangs but does not BSOD
* LinX reboots without BSOD

You know CPU VTT Voltage is too high when:

* Most users try and stay below 1.45V (+350V) for 24/7 use without additional direct cooling.
* The motherboard doesn't read the temp so you may need an IR thermometer to be sure you are not pushing VTT too far.

QPI PLL VCore (default: 1.1v, <1.4v is pretty safe)
What it does:

Keeps on-chip memory controller in-sync with bclk.

When to raise QPI PLL VCore:

* Try raising this along with Vcore and VTT, but in smaller increments.
* Helps stabilize higher CPU Uncore frequencies and QPI frequencies (in CPU feature)
* Try raising this when you increase memory clock speed via multiplier.
* Try raising when LinX produces errors after a few minutes without BSOD

Nice speed/volts! Do you think it can cope with even lower volts?

 

[Binge]

Possibly, but I like the stability I have now with the chip so I won't change anything until I'm VERY bored.

Hows temps on that voltage btw?

 

[Binge]

IDLE: 29 29 31 26

LOAD: 54-60 on any core... max 61C with core damage at 40 minutes.

 

[Thrackan]

29 29 31 26

Now I understand why you aren't bothered with lower volts...

 

[Binge]

these temps are only 2C lower than my C0. Temp wise this isn't really an improvement. I'm drawing about 60W less from the wall though. My PWMs are throwing off less heat.

That's valuable info imho. Less power consumption = less heat and with a bit of luck it's also more room for OC...

 

[Binge]

There's plenty of room to OC. Like I said... I'm just waiting to get bored. Honestly I'm too happy just to have my own computer again.

 

[Binge]

Bored

 

[freaksavior]

im going to run dice thursday then i'll see if i can hit 4.4

 

[Chicken Patty]

haha awesome binge, just awesome.

My watercooling stuff will be in tomorrow. Pump won't be in until later this week. I'll keep you guys updated.

I think part of the problem is the ram is running too tight, but I still have to put MemSet on this rig to get all the timings. I think it's trying to run 1600 MHz in the 7's.

 

[Binge]

dram frequency 1080??? Those sticks would do 8-8-8-21 @1.65-1.665V 1600MHz without any problems. Memset is a good tool. I hope that helps you.

 

[t_ski]

It's set at 1080 to rule out the memory. I can't push the whole thing balls-to-the-wall right off the bat. You know you need to test one thing at a time Tweak too much stuff at once and you don't know what's holding you back.

Edit: Corrected my last post. 1080 runs in the 6's. I think 1600 is trying to run in the 7's.

 

[Binge]

hahaha, yeah so true. I think you are doing well. Your VCore is basically your limiter at this point for a stable OC.
