i5 Overclock

:) All day yesterday played on flight simulator x and other gaming and watched dvd was no problem and stable.

:mad: Today switched on pc, went on internet surf for an hour and now got dreading BSD with 0x124 and I am so angry as why is sandybridge is a biggest jokes, passed all 10 hours on ftts and 10 hours blend test and passed 25x on linpack and was stable on gaming, dvd etc and now it no longer stable, getting BSD four times today as I had to push up 1.38v from 1.32v on the vcore and still getting BSD. Prime test is a joke really.

Totally fed up and so sick of tired of waste my bloody time of going all over again. God, I hate sandybridge right now. I am thinking of going back to bloomfield i7 920 as it always stable for a year! Why is sandybridge is so fishy! I wish Intel never put onboard GPU on the chip (that's probably caused BSD likely)
:mad: not very happy overall as I thought new firmware SSD and fresh installed of windows x64 had resolves it but it wasn't the case!

I rated bloomfield 10/10 and sandybridge 3/10 for best overclocking.

I cannot really understand why it so stable for 24 hours and then crashed down to earth with horror BSD! If prime passed with a stable, it should stayed stable all times (why caused BSD!!!!_ Intel, you are making this sandybridge a very poor overclocking indeed.

the reason your bloomfield was so good for clocking was because I picked you an epic cpu out to stop all the problems you were having,
onboard gpu has NOTHING to do with SB overclocking capability at all.

remember when you spent all that money on a 980X that you sent back under DSR because you couldn't overclock it?
you may remember how I put the CPU in a UD3R motherboard [not a particularly excellent overclocking motheboard] and achieved 4.3GHz within a few hours.

Bulldog. you really have no patience and it is getting quite tiresome reading these posts where you throw the toys out of the pram because you cant hit a clockspeed.

We all should complaint to intel then !

and intel will say one thing to you: does your cpu operate at its rated speeds?
the answer is yes. so you have nothing at all to complain about.

any overclocking is free performance. you need to clock YOUR cpu and not aspire your cpu to something it may not be capable of.

On what grounds? :rolleyes:
I'm happy at 4.5GHZ, a little miffed I got rid of my 4.8GHZ 1.35v chip a month previous, but live and let live.
I mean hell, my 2500k is under a PA 120.3 with my 6870's, I'm happy with the performance lol, you buy what you buy and enjoy it.

Then tell me what is the correct setting on z68 ud4 b3 for 4.6GHz then ? I don't know why it not stable enough ! I probably bring my pc down to ocuk and let you overclock it for me ?
 
I cant give you magical settings for your system.
have you considered that your CPU may not be capable of 4.6GHz?

I certainly wont be overclocking your system for you bulldog. your too-ing and fro-ing on the forums recently is a little much.
"I wont be buying a SB system"
"I have got a SB system"
"I give up with overclocking"
"I have purchased a 5GHz machine"

:rolleyes:

you have once again purchased a CPU which isn't a God-Like cherry picked example and have struggled to get it stable at a preconceived clock speed.

overclocking isnt about beating everyone else. its about buying a set of components and getting them to run at the fastest speed they can obtain.
this can be a long winded, frustrating and time consuming process. but if you want the performance gains then it is something you have to deal with.
there is no magic wand that speeds things up or makes things easier. its just down to luck and Trial/Error.

Whoa there bulldog, it’s not that bad.

You just need to be patient - as RJK has already suggested – overclocking isn’t an exact science and if you’re after high clocks it usually requires a methodical and ordered approach with the parts you have to hand.

The scatter gun approach very rarely works when trying to push the limits of your CPU. You need to remember that not all CPUs and MB are the same - even if they're the same make and spec - they will all have their own little foibles - that's what 'is meant' to make overclocking interesting/fun (for some).

Plus, as I’ve repeatedly mentioned throughout this thread

a clock can sometimes pass every stress test going but still fail in day to day usage.

Stress testing is a great early indicator for clock instability but, unfortunately, it isn't the 'be-all and end-all' in guaranteeing a stable clock.

You could 'try' and perfect the 4.6GHz with a bit more fine tuning (may not be possible) – but with your need for immediate results I would suggest dropping the clock by a mere 100MHz as 4.5 GHz is still an impressive clock out of stock 3.3GHz chip. And it could prove the difference for stability in day to day usage.

You need to remember that most of you earlier problems were software/firmware related, so in reality you’ve only been attempting to hit 4.6GHz proper over the past 2 days (that's not long).

You’ve not really given it enough time to identify all the quirks of your BIOS/CPU at that setting.

Get back on the horse...

Unfortunately Bulldog, without jumping on the band wagon here - it sounds like you may just have one of the less-fortunate chips that are capiable of clocking over 4.6Ghz, just like my 2500k which I struggled to get a stable 4.4Ghz out of.

As already metioned on here, only 40% of the ones manufactuered are capable of a stable 4.6Ghz overclock.

Edit - I agree with Plec above ^^ just give it more time and some more fine tuning.

I had now reduced by 100MHz clock speed to get it down to 4.5GHz and with same settings as before and is now solid and no BSD. Strange!

I leave it as 4.5GHz see how it go. I hope it staying stable for a week! If not, notch it down to 4.4GHz and so on.

I do get frustrated as I were expecting my chip to get 4.6Ghz to 4.8GHz but that now had to forget it. It nice to have 4.8GHz but I guess my chip is the unlucky one compare to my bloomfield cherry chip picked by rjk. Winner - i7 920D0 v Loser - i7 2600K

what about vcore and what level in LLC ?
Click to expand...

It was on my MSI GD 65.
Vcore is irrelevant, as my chip was pretty good, so you'll have to work around that yourself. Try 1.35v.
LLC was as "Enabled".

My chip, as far as I'm aware, was 5GHZ capable, buy my MSI GD65 blew its VRM's stressing at 5GHZ.
 
I did had stable at 4.6GHz once on vcore at 1.32v on LLC L7 but CPU PLL set on Auto. I try 1.34v on LLC Level 6 with CPU PLL at 1.60v

Here is my 4.5GHz @ 1.32vcore so far:

:) my new chip had arrived this morning, I was shocked to see idle temp start out 21-21-21-21 on 4.4GHz at 1.22vcore and under loads 51-50-51-50 for an hour. I am going to try 4.8GHz now :) That's that lowest vcore I ever seen ! My other unlucky chip need 1.30v for 4.4GHz.
