I would like to hire an expert to overclock my i7

Keith - it seems your request has created quite a stir here :D

I know that you asked for professional help, but perhaps you would be prepared to try one last measure in order to reach your overclocking goal. I'm no i7 expert, but what helped me with overclocking is the following:


  • Post some pics of your case and cooling setup. More detailed temperatures would also be appreciated - instability can be caused for a variety of reasons - the best way to indentify the cause (IMHO) is to simply rule out potential causes until you find the issue
  • Post your bios settings in detail and the methodology you have been using to clock, this may highlight some misunderstandings around the various voltages and/or settings that we as a community use to get our PC's humming
  • As above, what are your clocking targets and why? Is it purely for games or to simply reach a respectable clock?
I think if you can answer the above questions (it shouldn't take long) then perhaps your replies may be more positive.

From what I can gather and the little knowledge I have of OC'ing a i7, I would bet your ram is holding you back. When you increase your qpi, you in return increase your ram speed (or should anyhow). I'm at 3.8 with a 21x multiplier which puts my ram about 1440mhz or something in that range. If your ram taps out @ 1333, then you will never achieve your 3.8.

Please someone correct me if I'm wrong...

Buy some 1600mhz ram, and clock it to 1066 in your bios, then increase your qpi to 185 with your turbo on, speed step off. That would surely give you 3.8 with no probs as that is how I got mine. If you have read all of the guides you say you have, this should be a piece of cake. I would be more than happy to offer free help, but I speaka da engrish...

Step one, buy better ram.

Step two, bump this thread...

If RAM is an issue set up a different divider OR increase the timings AND/OR increase the voltage. (The latter 2 overclocks your RAM.) If your RAM still can't take the pain then you will have to do the former and use a divider to lower the speed to something it can handle.

Seems pretty strange why your i7 doesnt want to go past 3.7, as with my chip I can easily reach 4.2 on air cooling with 1 tweak of the bios. See my sig for my system, but it might be the ram that is holding you back going as far as I am at the moment
 
Has no one contacted the OP and scored 50 squid yet? Sounds like there are plenty of chaps in this thread who could supply the service.

I don't agree with the point about needing a basic element of intelligence to be able to oc - some people will find it very easy and others won't. I think you really need to have the knack to do it well - overclocking a machine properly and safely seems almost akin to an art form.

Now I'm not stupid (techie for a G&G software company in the Oil and Gas ind), but I find oc'ing a pc to be a real mixed bag with lots of pitfalls. Tbh it's one of my least fav aspects of building a pc.

I think its more down to preference - the OP has tried (to what extent we don't know) but now cba and would rather pay for the results. I'm sure most upwardly mobile people from all walks of life could build a pc and do a decent job. However, this hasn't stopped people like Mr Dell from coining it in thou has it ;)

Seriously, the time it took the write this thread could have been invested to read any guide on overclocking to get a handle on the basics.

That is true, but this guy wants to take all of the headaches out of doing this job. All he needs is a D0 stepping i7 chip with a decent Noctua cooler, and then the rest of the job for someone would be mighty simple. I can understand where he is coming from tho, because if it wasnt for me buying a new machine from here and having it OC'd for me, I would have been scared stiff on doing it myself, as it isnt a simple process. I would recommend rjkoneill for this job, as he is the guy that OC'd my new machine for me, to the point where I increase my BCLK speed up or down for the speed that I want :D
 
Okay folks.
After 2 months of trying and lots of BSOD's, I finally managed to overclock to 4.20 GHz stable, however I downgraded to 4.02 GHz because of the high temperatures.

Here are the BIOS settings:
Code: 
Multipler: 21
BCLK: 193
CPU: 1.48v
PLL: 1.8v
QPI: 1.3625v
DRAM: 1.5v
HT: OFF
Stability: 8+ hours with Prime95

Temperatures are not going more than 80C.

p.s. I still use the same parts as in the signature.
 
HT off = /fail on i7 IMO you may have well just gone a got a normal q series, waste on money. May i suggest a different hobby...like collecting pet rocks.?
Nah j/K well done for finally getting stable:D
 
Your QPI/PCIe is to high
keep it under 1.3500v for max stability.

1.48v is to high on a i7 aswell for the clock your going for.

and with HT off like the pervious guy said you will only bee useing 4 threads not 8 threads and on a i7 its pointless.

try this

turn down your multi

and shoot for 4.0 with HT

20x mulit
200x bclk

reduce your settings to 1.325v for vcore
cpu pill 1.8v
cpu VTT 1.35v
Qpi-PCIE 1.3200v

good luck .
 
At the moment I have got my Multi to Auto, BCLK @ 191, Vcore @ 1.300, Cpu PLL 1.80v, Cpu VTT @ 1.325, Qpi-PCIe 1.325.

With these settings, I no longer get a BSOD, but after 6 hours of Prime it fails on 5 cores. What could I be doing wrong?

well thats a simple answer to your question

Up the vcore 1 more notch and you should be perfectly stable.

also forget about prime 6 freakin hours LOL
thats a thing of the past run Intel Burn Test, 16 threads,20 passes

if you pass that consider yourself stable.

running IBT stresses your cpu out like no other sometimes 5-10c higher in cpu temps.
20 passes is like running prime for 7+ hours
 
OP has a C0 so doubt it would do 4ghz on 1.325v..

I have been IBT stable but failed Prime, you shouldn't rely on just one test to prove your stable, a good overclocker will have many tools ;)
 
I didnt realise that Prime was a thing of the past, as I thought this was the most definitive way of making sure your whole system was totally stable, looks like I stand corrected

If you only use one tool to determine whether your system is stable, then you are a complete implement. ;)

Prime 95 shows that your computer can calculate prime components...
SuperPi does the same, but digits of Pi...
3DMark tests graphics components and some computational sub-systems (memory and processor), depending on the version.
Encoding/transcoding/whatever it's called now tests a wider range of processor and memory funcitons...
Ad nauseum.

No one test will tell you a computer is stable. Just like driving a hot-rodded car in a straight line won't tell you it handles well.
