Having Bad Time OCing 3570K

[McLord]

Hello AT members.

I am new to this forum as well as OC. I have read many guides here and there and I think I am familiar with most stuff regarding OC'ing, however; from my observation from 3570K owners, I concluded that my chip is not that good to overclock

System Specs:

Intel 3570K
ASUS Z77 PRO V
Cooler Master Nepton 140XL Cooler
G.SKILL RipJaws DDR3 1600 CL9

Now, for the OC settings, I have went through lots of configurations till, I was able to finally boot without BSOD. Yaaay. Well not so fast, WHEA error are thrown in my face

The current settings are:
BCLK 100 MHz, 44x Multiplier, High LLC, 110% CPU Current Capability, Optimized Power Phase, 1.245 Vcore. 1.264 @ idle using CPU-Z. All values are set in the BIOS.
I am trying to achieve 4.4 GHz. The OS boots OK, but WHEA errors are thrown.
I am using Prime95 v2.66. Temps were like in 73~76 on all cores (Core Temp) and 58 for the CPU (AI Suite 2). I don't want to mention that I used IntelBurn and the temps were like high 80's. I stopped the Prime95 as soon as the first WHEA error was thrown.

What are the steps I should proceed with next?. I really don't want to go with higher LLC and I am not sure if 1.25 Vcore is OK.

I have read this thread here: http://forums.anandtech.com/showthread.php?t=2349626, but going up to 1.3V... Nooo :'(

Thanks in advance.

While I haven't done extensive OCing on the 3570K, I think that you probably need more vcore, and perhaps better cooling.

You might have to disable C3/C6 states under advanced cpu options. Do keep in mind idle power draw will increase fairly substantially if you do so. If you don't want that stick to 4.3GHz.

Also, in my experience Prime/Linx etc are not very indicative of stability. Keep checking for whea errors after running normal apps/games. Also try stuff like Dolphin emulator and Arena chess simulator.

Try Voltage offset of .05 and run Bclk of 104 X 43..
Below guide from Asus is long but should help (especially last 6 min.)..

I have added these 500mV and it seems it is stable now under 1.25V.. One hour of Prime95.. I don't think I can get any better cooler for now. We all know that P95 loads are not realistic at all, but perhaps re-applying the thermal paste?

You could go with fixed Vcore instead of offset mode, and disable C1E and turbo.
That's my preferred method of overclocks (and yes, I know that I have higher idle power draw).

Have a similar setup at the office (3570K + P8Z77V Pro). All I can say is, even though I got 4.5GHz stable, I still hate IvyBridge. OCing SandyBridge was a breeze.

I am already using Manual Mode with Fixed core at 1.245V but with Ultra High LLC to overcome vdroop since while using High LLC, it only goes up to 1.232V... Not a good sign.. Regarding most of the BSOD, it had 0x1E Error which is corresponding to "Increase Vcore"

 

[crashtech]

I used to set those current limiters way up out of the way, like 200A or 200%, whatever the max setting is.. That way they are out of the equation. If you feel you need them for safety, bring them back down again when you are done and see if they interfere with the OC. But if the voltage is manually set to a sane level, amperage by definition can't get too out of hand.

 

[McLord]

What are current limiters? Excuse my ignorance. I am not happy with Ultra High LLC. The votlage shoots up to 1.264 which more than really needed for my overclock. While High LLC is only up to 1.232. I tried going low to this voltage, but I get a BSOD when the windows boots. Really dunno what to do.

 

[crashtech]

Where you mention "110% Current Capability" in your OP, that would be where current limits are set.

btw, opinions may vary, but if you are staying under 1.3V at full load, I don't necessarily consider that a failure.

 

[Burpo]

Exactly, current limit should be set at 130% (minimum) at 4.4Ghz.

 

[McLord]

@crashtech, Aha.. the CPU Current Capability.. yea yea.. Got it. Well I was sable to achieve 4.4Ghz(Stable so far) with Medium LLC @120%. BLCK: 104.8 with 42x Multiplier / Offset of 0.05. I had to lower my RAM Speed. They are bad overclockers at @1.5V. Under LinX full load, the Vcore reaches 1.256V. I think this is not bad at all.

quoted from BenchmarkReviews

Advised to be set to regular to limit aggressive overvolting especially if higher manual vids are being defined for VCCSA voltage. A nominal value of 1.100 with a LLC of regular offer solid vid support for configurations at 1600MHz (including 8 DIMM configurations) for speeds in excess of 1600 first try 1.100 vid. If stability fails to be met first consider setting a more aggressive LLC setting this (between high or extreme) these parameters should yield better results for modules up to 1866 and potentially 2133. Should stability still not be met consideration for VCCSA ranges of 1.200 to 1.300 can be consider but are not generally recommended.

Even though they said Regular LLC @110%, BSODs were trailing me.
