ex58 ud3r overclocking overclock method that worked for me 4.2ghz

QPI inverse scaling, and final ghz acheived
edit note > make sure you case is well ventilated ie no heat build up overtime inside case and you have the best cooler you can afford mine was a megahalems for this guide.
hmm, ive got to be honest and say that to prove absolutely tangible evidence of inverse core temps with higher QPI would be pretty arduous, and im thinking perhaps i should now take a break from OC testing and install some stuff, especially as the volts various i7’s are happy with seem to vary allot, so im guessing proving it will have to wait until ive got the time, to run some very scientific tests. but certainly the message from all my experimentation seems to be certainly for my setup that when QPI/VTT is AUTO set, i seem to be able to get to the higher speeds with much less trouble, as I’m currently stable at 4.2ghz im probably going to stop there, i’m writing this running prime quite happily at 4.2ghz full load for the last 2hrs, and she passed IBT (Intel Burn Test) on maximum for 3 passes without being above 82c on any core, I’d say IBT is the only stress test that can properly test stability to its extreme over the short term (5-10 mins) and that prime95 serves only for long term stability testing(hours, days etc), under prime95 blend at 4.2ghz its not going over 78c max on any core, PCH 32c and CPU 56c wierdly with this all my settings are auto ! apart from QPI PLL set to 1.28v (stock 1.1v) and CPU PLL set to 1.88v(stock 1.8v), one thing that worries me is now and again hardware monitor records a minimum cpu fan speed of 0rpm for a second or something, but this is another issue im sure this must be a software glitch but im going to check over everything, full fan spin downs seems to be 15 x longer than this 0rpm glitch appears for as I only see it ont he minimum column of hardware monitor and never catch it in the value column itself, so i think im ok eek. apart from the QPI pll and CPU pll being manual
this is what the bios is choosing to use volts wise for the other AUTO settings :

so settings in resume for me are :

bclock 200mhz and cpu multi 20x (turbo enhance enabled which pushes to 21x ie 4.2ghz stable)
this setting above might be whats making 4.2ghz a doddle on my machine ? as 4.2ghz starting with a 21x multi seemd much harder to acheive stable style.
also EIST is currently disabled not sure this is helping will turn it on at some point, so CPU-z reports my processor as running at 4200mhz constant as turbo seems to be permanently on in this scenario ?
Hyper threading is off (i figure iwas pushing my luck with HT at 4.2ghz on air ? another time ill test though i dont think HT is worth the temp increase it yields compared to higher OC.
QPI multi is 36 x
so QPI seems very happy at 7.2ghz
on the ex58-ud3r bios Performance enhance is set to extreme ?
auto sets CPU vcore to 1.4v in bios but in software ranges from 1.360v to 1.380v (stock vcore1.2875)
load line calibration is on, CPU-Z observed under full prime95 load it seems to run at 1.36v constant.
auto QPI/vtt is ending up at 1.515 (stock QPI/VTT 1.175)
auto set IOH core to 1.3v (stock 1.1v)
auto sets ICH I/O to 1.5v (stock 1.5v)
auto sets ICH core to 1.1v (stock 1.1v)
auto sets DRAM volts to 1.6v with my ram set at 1200mhz and 6.0 spd
auto sets PCIE to 1.5v
manual QPI PLL 1.28v (stock 1.1v)
Manual CPU PLL 1.88v (stock1.8v)
nb if pushing RAM to 2000mhz dram v goes upto to 1.7v but at 4.2ghz im running memory at a 6x SPD at 1200mhz this helps allot ?

all these auto volts settings were viewed/discovered with gigabyte easytune6 booted in windows ? so im guessing since this a gigabyte motherboard

theyre very accurate ? I know auto OC settings for everything other than QPI PLL and CPU PLL goes against all the grain of OCing law ? but my setup when set like this seems more stable than any other way, I have set it up, and it would be interesting to see if some people who had problems with 4ghz and above could try the same approach and see whether it worked for them. obviously you do this at your own risk, and most in the OC community would say that QPI should never be as high as 1.515v, ie 1.35v max for QPI/VTT ?, and they might be right as im willing to risk it on the basis im prepared to risk the effects as 77c max and the fact that auto set QPI/VTT when running 1600mhz and 2000mhz ram at stock CPU 2.66ghz speeds always seems to be 1.5v for me anyway : so can it be so wrong ? but see what your board auto sets QPI/VTT to when you run 4ghz and above or with memory at 1600mhz and above ? and reply to this thread post with your discoveries as i would love to know ? youll need easytune6 to view these auto volts settings from windows so im guessing only people with gigabyte boards will be able to do this ?

my MB is a EX58-UD3R v1.6 bios FG (listed wrongly as 1.0 earlier in thread)

Im going to upgrade the bios soon im hoping it doesnt throw all my settings out otherwise ill have to retrograde the bios, as these setting took too long to find for me perosnally to lose them for a BIOS update, but hopefully the BIOS update wont change the functionality of any of these Auto v settings.

I also decided to underclock the RAM ? as this seems to make it more stable at 4.2ghz I run my stock 1600mhz ram at only 1200Mhz ie the minimum 6 x SPD ram multiplier with a 21x cpu multi at bclock 200mhz, as this seemed to work for me perhaps its a trade off, between running the ram high or running the CPU 4.0ghz and above as at the moment i cant work out how to get both, as the major cause of instability for me seems related to syncing high mhz memory with the bclock set high enough to get 4ghz and up and when I do push higher with ram speed the auto set QPI/VTT seems to go higher still upto 1.55v ? but this doesn’t seem more stable at this point.

so a recommendation from this memory experience would be if 4ghz and higher is proving difficult for you, clock your ram lower it should help, though i wouldnt go below 1066 mhz as this would be a bit nuts.

also if 4.2ghz is proving difficult try a 20 x CPU multi with bclock 200 with turbo enhance on (and possibly eist off ? maybe speedstepping frequencys at 4.2ghz and down is more difficult for the CPU to handle the v fluctuations successfully ? but this is just what mine happens to be and works i have not tested whether speedstep is causing issues)

now that ive come to the end of OC’ing my i7 for a little bit 4.2ghz is more than i could of expected, i must say its been an interesting experience, thanks for all the help in getting to this point, and I hope this post proves usefull to someone in getting 4ghz and up.

improvements to test

I will report back once ive turned speedstep back on to determine whether that creates any instability issues, if not ill probably have that on as running constant at 4.2ghz seems a bit energy ineffecient though idle cores range between 40-46 after 3 hours on.

my next step might be to set these auto settings manually and see how stable it is with them set manually, and perhaps to then push lowering vcore to try and prove this inverse theory ? but at the moment I dont have time to go this far.
Wierdly with these auto settings all set manually i thought it seemed less stable which I cant really explain ? the reason why i decided to manually set QPI PLL and CPU PLL is they seemed to be the two settings that auto didnt raise in any way ? as i went higher with the bclock, and this is only a theorisation but since it seemed to handle raising all the other values well by itself, that perhaps these apparently static values on auto were getting out of sync with the rest, so i reasoned to raise them up, and this seems to help with stabilisation for me.

I do wish there was some totally clear scientific explanation of how all these volts settings inter-relate with each other and what ratios need to be preserved for stability, but i guess only the Intel i7

engineer who overclocked his own PC could tell us ? I wonder what speed he’s running at and what he understands about the i7 that the wider community doesnt ?

the irksomeness of having to deal with female genital mutilation within our cultural borders

It would be nice not to have to deal with these problems in our country in the first place or have to even consider FGM, Oh I forgot there is a simple solution its called not allowing these people to enter the country in the first place to devolve and distract our culture from more important things, than concentrating on trying to solve a genital mutilation problem we never had to deal with before importing backward peoples ! but of course that would involve having border controls that weren’t porous like a sponge because of Europe’s insanity, or having some liberal enforced agenda of immigration and multiculturalism under some vague guise that nativity in itself must be racist if your white or western.

and why do we show pictures od distressed white children in this article, is it because were too feared to label the practice with imagery of african immigrants ?

BT rip off NON use Line Rental charges

Extra bill charges for non usage, whether it’s in your small print or not, I consider these charges as unfairly described or offered within the advertising, non usage of a service should not incur extra fees, I will be taking this up with the ombudsman unless resolution is swift. When I buy goods or a service like a monthly line rental, I expect to see a flat price advertised that does not involve hidden conditions relating to being charged extra for none use of said services, beyond the flat fee advertised as the services cost. If these charges are not removed from all the months in which you been charging me well beyond the headline line rental price I signed up for on your website.

I would also like to know at which point you can provide evidence agreed to be on Unlimited Weekend plan ? As I do not remember signing up for a £14.60 line rental ? also you are charging me for £2.70 for caller display I would also like to know what evidence you have I signed up for that extra as well, as you appear to be charging me extra for that due to non minimum call being made, all of this extra charges for use stinks of deceptive business practice in my opinion. have not had a telephone attached to my line for some considerable time, over which period you have been making the extra charges to my monthly costs via direct debit.

Amazon Marketplace issues with template based selling

For the last 3 items I have bought of amazon, I have found some serious flaws with the way they are selling goods, they allow amazon marketplace sellers to sell items under a kind of amazon template for that item, without really having anyway to police such misbehaviour.

1: Misdescription : Seller selling factory refurbished or refurbished items as new, happened with a hard drive I bought.

2: No photos uploaded generally to show condition of second hand items etc, dependant on poor or possibly inaccurate word descriptions, makes 2nd hand book buying a lottery.

3: Not explaining that the warranty was also with the amazon seller and not the manufacturer.

this makes buying certain items on amazon a total lottery.

stock market speculators casino table

One commentator was heard to state as observed by dailyfinance.com :

“People have to separate the economy from the stock market,” Ed Butowsky, managing partner of ChapwoodFinance.com in Dallas, said.

In other words as I have suspected for some time the stock market has little relationship to reality or the state of the economy its a gambling table detached from reality or the state of the economy. the gamblers have no need to know of the state of the economy or the general population, in assessing the value of their fictional commodities, it’s based on how many people they can sucker into playing their imaginary game read usually large ignorant institutional investors, after all … they have a billionaire row lifestyle to maintain and if you cant achieve such earnings when being connected to reality then the best thing to do is to detach from it entirely. And get back to the game you do know, inventing and imagining vast profits in computers containing numbers on a screen for vast half fiction financial entities. And then converting them into tangible real assets so that when the shit inevitably hits the fan, you got yourself covered because you converted it into land, property or businesses that do something substantial.

The real con revolves around peddling something of low value as something of high value two one investor and also selling your end of the deal, responsibility wise for the first transaction as another credible form of investment to a second investor, ultimately having detached yourself from responsibility for the transaction entirely, and then quickly converting both the peoples money into a diverse range of much more solid tangible forms of investment. And then when discovered persuading your friends in power to bail you out of the situation with more mugs money (read … taxpayers) whilst you golden parachute out into tangible fat house and investments to sustain you in old age, the financial markets are little more than a criminals legal paradise or even worse consolidate the value of the phantom investments / cons with taxpayers money.
