Baffled about this Situation

I wonder if someone could shed some light on this? I have an ASUS P8Z77-V LX with i5-3570K Gainward GTX660 and 12GB Corsair Vengeance 1600MHZ along with a Corsair Force 3 SSD.

To me this should be ample hardware to get at least 4.50GHZ without much fuss, however not the case. For instance right now I'm running Prime95 testing my clock which is at 4.4GHZ on a negative offset of 0.005, Core Voltage rock steady @1.224v and the MAX temp seen during Prime 8k test was 73c.

If I want to push this up to 4.5GHZ everything goes through the roof, Prime will crash and burn if the Offset is less than +0.080, or 0.096 depending on what mood it's in with temps 86c during the same 8k test. and Core Voltage jumping about between 1.296~1.304v

How come I need such a lot more for such a little increase?:confused:

Hi, it could well be your chip clockability, but it could be a bios setting as well, what are your ram timings + voltage set at? You might just have to relax the timing settings or a bit more volts or both.

You've hit 'the wall', it appears.

Noctua NH-U9B-SE2

OLDPHART what would you recommend I relax the timings by? I haven't done this before


Edit Update: Now I'm really baffled :eek: I've just tried another OC, and then loaded the profile I had saved in BIOS to go back to the OC mentioned in the above post, to my amazement it crashed even before it loaded into windows, not just once but several times :( What I had tested for several hous with Prime, made no nevermind as it seems it was unstable anyway, so where to look now? So.... entering x46/ LLC Extreme or Level 5, +Offset 0.096v and what the Hell! :rolleyes: this actually is more stable than the x44 with the negative offset 0.005v. having said that, although this seems stable as I checked it with Prime, and OCCT, and no errors whatsoever, I do need to get a better cooler, as temps hit over 90c. So I'll lock this in bios,and leave as is until I get a better cooler. How much lower temps can I expect on a Corsair H80 ? as that's what I'm looking at getting. n.b Forgot to mention Core Voltage @4.60 is 1.336v

Hi, your spec ASUS P8Z77-V LX with i5-3570K Gainward GTX660 and **12GB Corsair Vengeance 1600MHZ** along with a Corsair Force 3 SSD -

**12GB Corsair Vengeance 1600MHZ** ---> Are you using a Tri-Channel KIT 3x4GB? of ram as your mobo > ASUS P8Z77-V LX is Dual Channel - increase the voltage from 1.5v to 1.6v try that at 4.5Ghz. If that does not work take a stick out try again.

Read this review see if that helps - http://www.hardwareheaven.com/revie...r3-1600mhz-12gb-kits-review-overclocking.html

Corsair Vengeance 12GB DDR3 1600Mhz (3x4GB) PC3-12800-CL9 (9-9-9-24) 1.5V CMZ12GX3M3A1600C9-Lifetime Manufacturer Warranty.
Corsair Vengeance 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit (CMZ8GX3M2A1600C9)1600MHz RAM Speed, CAS 9-9-9-24 Timings,*** 1.5-1.6v VDIMM***, Lifetime Warranty with Corsair.
 
I was in the same situation a few weeks back, i got rid of offset overclocking and stuck with vcore adjustment and using the turbo core multiplier and managed a nice 4.7ghz at 1.4v! Couldn't ask for more than that.

Try it, see how far you can go with vcore and a low llc and cpu pll voltage to keep temps down

If I enter the settings shown for OC RAM, it stays at 3.8GHz no matter what I set the turbo at, for instance I enter x45, turbo ratio say 45, so why when I reboot and run prime, does everything run at default clock, showing 3800.00 this is crazy I think my hardware is knackered or I was sold some faulty hardware.
 
Starting all over again from scratch, reset the BIOS and set defaults. Then entered the following:

Ai Tuner = Manual
BCLK/PEG = 100.0
Asus Multicore Enhancement = Enabled
Turbo ratio = Manual
Ratio Synchronizing Control = Manual
Turbo ratio x 46 (All 4 cores)
Internal PLL Overvoltage = Auto
CPU Bus: DRAM speed ratio = Auto
Mem Frequency = Auto
EPU Power Save = disabled
LLC = Auto Power Phaze Mode = Standard
CPU Voltage Manual Mode/ Manual Voltage 1.340v
DRAM Voltage 1.500 Auto
Spread Spectrum = Auto

So far this is all I have set on the ASUS board mentioned in the previous post. the voltage when manually set at 1.340 is in RED is this ok? or is it something I should be cautious about? CPU-Z reprts that the Core Voltage while Idle is 1.344~1.352v and core speed is Idleing at 1600.00MHz

I wasn't getting anywhere fast with Offset, so I'm curious whether it's fine to leave things the way they are as described above? Any suggested changes are welcomed in Advance, Thanks Guys :)


@Jay85: I only have 2 options on my Asus board for CPU PLL and they are Auto and +0.10v so it looks like I cant lower the temps that way, do you know of any other way to lower CPU PLL volts?, or does anyone else know?

Edit Update: Taking into consideration that leaving LLC on Auto adds an approximate of 0.016v to the vcore of what is manually added, this equates to a manual imput of 1.249v being in actual fact 1.256v whilst Idle in Windows, and 1.264v whilst under Prime stress. End result.......CPU-Z Idle voltage 1.256v under a manual setting of 1.249v, Idle Core Speed 1600.02 Idle Temps 36c Full Load Temps 71c

did the same this last week but 4.5 is my limit on this cooler .

thinking of getting h80 or a big air cooler decisions descisions :p
 
I'm looking for someway to compensate for the lack of options with my CPU PLL setting, ignore the manual vcore, as I got this from another forum, as I cant figure out how to take screen shots while in bios, however this is the board I have, please note on the right, the Min/Max setting for this option, the question is, is there anyway of lowing these cpu pll volts to get lower temps, it's either stay with 1.80 or add 0.10v or am I permanently limited with this particular board

I along with quite afew people have found CPU PLL to not lower temps, when i set it to 1.5/6 i found no difference in temps or stability, so left it as is.

I'm not sure but the PLL isn't going to dramatically lower temps, it might knock off .5 of a degree.
