High voltage needed for 3570k - Page 2

post #11 of 25
Oh wow, I thought mine was bad. I'm at 1.560v (not a typo) for 4.8ghz on water to be Prime and WHEA error free. Temps on water are in the high 90's running Intel Burn Test.

What BSOD are you getting?

it varies.


My temps arent even the issue. Even running with a 45 multi at 1.4v i still only get high 70's, few spikes to low 80's temps (just did that to check temps)

Hmm. Have you tried playing with ram timings at all? I'm not sure what your ram specs are, but loosen your timings up quite a bit and maybe add .5v (1.5 to 1.55v) and try running prime again.

Also, what Prime FFT are you running? Small, Large, Blend?

Edit:

What's your VCCIO voltage?

Sin's guide points out that temperature is crucial. That's the only variable that you're not talking about, and since everything else seems to be more a less a static factor I'd take a stab that's the main cause of your problems.

We can see that not only is the temperature decrease having a great effect on the power consumption (representative of leakage), but also an exponential one, as at around -60C on both runs we see a leveling off of the power consumption. However as the temperature rises the increase in power is much more than it is when the temperature is lower. This confirms that the leakage on this CPU is very heavy, we can also see that the leakage is being decreased exponentially as we decrease the temperature.

So how can this help me OC? Well keep this in mind, for every degree you can reduce the temperature of Ivy you are decreasing the leakage at a faster rate than at the degree above it, when you do this you are increasing your opportunity for higher frequency at a much faster rate. So always keep pushing at better temperatures, with Ivy Bridge EVERY degree counts more than the degree above it. At around -60C this effect subsides, so phase change would be a point at which the power scaling starts to end.

AKA: Same voltage, lower temps (better cooling/ambient temperatures) = higher frequency @ same

See the graph:

So where are you located and what are your ambients? I'm running a 3570k as well @ 4.2ghz @ 1.176 @ 70-80F ez pie, haven't even begun to clock higher yet, need to get around to doing that tongue.gif

I just run the blend test on prime
and I dont have a VCCIO setting on this motherboard, only a VCCSA

And no, I have not messed with ram except for voltage. Timings are all on auto and the voltage is 1.5

Try manual setting your ram timings (9-9-9-27 2T for example) to stock settings and give it a shot. I've had on more than one occasion, errors in Prime or WHEA errors as a result of ram timings being too tight, or not enough voltage.

Ram is running at what specs say, 9-10-9-28 2.

Tried to run prime95 last night even on 4.5 while I slept, prime would run fine for a bit then after about 20 min I would get BSOD. Even up to 1.37 vcore at 4.5.

Don't listen to everything that you hear on the forums. The people that do get these really good chips are the ones posting benchmarks over and over. Your chip is normal. Thats about what you should expect from an average i5 3570k.

I have owned my fair share of cpus and not once have I ever gotten one of these great clockers that you see on the forums.

I feel like my post about temps is being ignored... I believe that's 1/2 of it besides the silicon lottery.

OP what cooler are you using? And what are your ambient temperatures? What's your case cooling? What's your temp under load?

OP is it a "Costa Rica" chip?
