Re-Boot after Over Clocking !!

post #1 of 26
Thread Starter 
Hey everyone, I'm just new to this overclocking frenzy so please don't laugh at me if I come out with the most silliest questions, I really do need some help/advice with this =/

Anyways I got myself the Intel i7-2700k with the Z68X-UD4-B3 Gigabyte Motherboard, Nvidia GTX570, 4x2GB Kingston Memory (1600), Asetek Water Cooling 570LX...

I have been able to overclock the CPU to 4.60GHz with the multiplier set at 100x and the core voltage being 1.35v

I have tampered with the memory also, i've selected the extreme option (there's normal & turbo also) with Extreme being the highest. It's sitting at 1600... however from start up it takes quite sometime to get to the desktop window (around 53 seconds). It's booting with the 128GB SATA III Crucial M4 SSD. Before I overclocked it, it was around a (37 second boot from power on.)

I think I've done something wrong, hell I was even going to pay someone to over clock it for me so I don't **** it up!!! Anyways I ran real temp 370 software to see what the heat was like when idle. The idle cpu temperature was around 27'c - 36'c ... when I ran the xs test, it checked the temp while running at 4.6Ghz. And it reached around 42'c to 54'c.

Also when I ran real temp 370 when it tested at full cpu usage of 4.6ghz... the voltage only reached 1.28v ?

Can anyone explain if I need to change the memory speed, voltage or whatever it may be, I just don't get why the boot up time is very slow, almost 20 seconds slower... and I apologise for the little knowledge I have with overclocking. There is probably another section for this topic to be put in but I'm in a rush!

Any help will be appreciated!

Ok, first of all, revert everything back to stock. Always overclock only 1 thing at a time.
Slow boot is a sign of unstable OC.
Second, I doubt that your multiplier is 100. That would give you something in the line of 10Ghz. (100Mhz Ref Clock * 100 multi = 10,000Mhz)
Anyway, leave that 100 be 100, find where it says 35 (i think?) - this should be your multiplier. Raise that to 38, test, raise to 40, test, raise to 42, test, and so on, you get the point.
You test with Intel Burn Test or other cooking utility. Always monitor your temps. Now, I can't tell you where the safe temp limit is, because I don't know this chip, and Intel savvy has to tell you that.
But in any case, 10min IBT run after every multi bump to check for basic stability, with constant monitor on the temps.
Once you reach the OC you want, or the temp limit, make a longer IBT run (30min, 1hr). If it's unstable, reduce multi by 1 and repeat.
Once you pass 2hr IBT without crashes or overheats, you're good to go smile.gif

Also, I strongly suggest you leave the RAM at peace right now, anything other than stock will only mess your OC up.

I agree with everything in the above post. Those are pretty good temps for 4.6, you can probably take it a bit higher if you have good hardware.

Also fill in your sig rig on your user page like we have so you don't have to post all of your hardware when you have a problem thumb.gif

Thanks you guys, I will get back to you asap about my current newbie over clocking!

Yeah I will fill the sig thing in too =)

oh and erm... when i ran the realtemp 370 the cpu hit a max of 55'c and it wouldn't go over that... however I ran prime & soon as I started the stress test, it went to blue screen!!!

wha-smiley.png


--UPDATE --
I ran a burn test for the CPU at 4.60GHz with a voltage of 1.345v
Burn test lasted 15 minutes, throughout the test the CPU reached a max temperature of 58'c and that was at 55-65% CPU Usage.
The GPU seemed fine at 39'c
The test came back as FAIL, considering I had no CPU errors detected???

Do you think it would be better to lower the voltage to 1.340v for the 4.6GHz speed?

Hey, I can't seem to stabilizethe 4.7GHz so far... I was able to get it working at 4.6GHz without a problem.

This is what I have so far -

CPU Clock Ratio (47x) 4.70GHz (100 x 47)
PWM Frequency - Auto
OVER Current Protection - Auto
Internal CPU PLL Overvoltage - Auto
Multi Step Load Line - Disabled
CPU Vcore - 1.375v
Dynamic Vcore - Auto
VTT Voltage - 1.050v Auto
CPU PLL - 1.800v
DRAM - 1.500v Auto
Memory - Extreme (1600)

It just doesn't seem to agree with performance or burn test thinking.gif

I also don't understand why according to CPUID the Vcore voltage has went down when playing BF3 on ultra settings. I've made it 1.38v and it's stating it's around 1.31v ???

Back Again...

Okay people I have a slight problem. My CPU right now is running at 4.8GHz with a Vcore @ 1.350v
Multi Step Load Liner - Level 5
VTT - 1.050 (stock)
DRAM - 1.500 (stock)

I was able to pass the burn test without any flaws, Ambient room temp around 16'c & the peak temp for my cores were around 74'c @ full load.
I also played battlefield 3 & Crysis on both Ultra High Settings for an hour and no problems.

HOWEVER... When I run Prime95 it takes 10 seconds before it gives me BSOD with error code #0124 which I know seems to be something to do with voltage. But I don't know why burn test and games work without cutting to the BSOD. Do I need to tweak the VTT & DRAM voltages. I read something about them which said I had to =/

revert your bios settings back to default then,
follow munaim1's guide and also $ilent's overclocking guide.
after reading your posts, its easy to assume you have little to no knowledge on overclocking.
these are GREAT guides.

munaim:

$ilent:
http://www.overclock.net/intel-cpus/1100100-info-intel-2500k-2600k-overclocking-tips.html

and there is luke who wrote up an offset guide though i find it a little complicated. i just took what munaim said and used it. it worked pretty well for me

luke's thread for offset:
http://www.overclock.net/t/1219588/offset-mode-overclocking-starter-guide-and-thread

i hope you understand it. if not, munaim1's guide will have you there.

Your still unstable somewhere, at 4.6 how long does it take to throw an error code?
post #9 of 26
keith, he needs to read some guides. he keeps lowering voltage while trying to go higher.

and he still should fill out his system specs.a month later he isnt stable from originally posting and didnt fill out hos specs then
