If someone has done it on asus maximus boards please help! smile.gif

Ideally I wanted to have a 4.4ghz with 1.35vcore, uncore at 3.9 or lower with 1.2(?) and to use adaptive for that? Or there is no need and If i set both manually (vcore and uncore) it would be ok ?

thanks again!

I'm typing from my lappie at the moment glancing over at the desktop sitting at 45 Multiplier /45 cache ratio .....

Cure Frequency = 0.80 Ghz
Core Voltage = 0.72
Max Core Temp = 27C
Rad Fans = 444 rpm

I'd suggest saving your settings under one of the OC profiles and then setting everything to defaults.

With RAM at 1600, start at 4 GHz working ya way up slowly.....set CPU multiplier at 40 and voltage at 1.15 .... run RoG bench.... if it fails, up voltage till ya get a pass.

At 4.2 I started with 1.15 volts and passed
At 4.4 I started at 1.25 and failed, was stable at 1.275
At 4.5 I started at 1.275 and failed, was stable at 1.287 (new BIOS pushed it to 1.32)
At 4.6 I started at 1.325 and didn't get stable till 1.38

After each stable run at 1600, I then went to XMP 2400) and repeated.... only the 4.6 setting required a bump. Once past that, I pushed cache ratio to match CPU multiplier, none required a bump. Then new BIOS came along and 46/46 was not stable....46/43 worked but I don't wanna waste time fiddling with settings until i decide whether to move to 1203 BIOS and waiting for response from Asus before I undertake.

I had rather modest OC goals at 46/46 ..... I wouldn't mind 46/43 as my testing with RoG Real Bench image editing showed no performance difference between 46/46 and 46/43 .... after that performance started to tail off. But my thinking is the less settings ya change the better. So rather than start of from the getgo with lotsa changes, I'd go minimal until ya 'hit the wall" ..... save this profiles in the OC section of ya BIOS and then use this guide to tweak from there.

If you would like to give a shoot at 4.6ghz than probably put down your Uncore to 41-43 so you can get the voltage below 1.3v for it.

Cheers

Thanks for the input .... but the problem I am wrestling with is I was perfectly stable under BIOS 0804 at 1.38VID .... adaptive took it to 1.408/1.424. My problem is Asus required that I upgrade to 1102 before they'd talk to me about a wireless issue (which I later solved myself) . And with the new BIOS ....

Stability required VID move from 1.287 to 1.325 at 45/45
Peak Voltage under RoG Real Bench went from 1.328 to 1.440 (rather extreme change)

Stability required VID move from 1.36 to 1.39 at 46/46 which left peak voltages over 1.50v
back at 1.38 was able to do 46/43 at 1.38 VID
Peak Voltage under RoG Real Bench went from 1.408 - 1.424 to 1.44 - 1.48 (again rather extreme change)

Of course outside the benchmark I don't see anything near that but still wanna get an understanding of whay it has changed so much before going further.

In BIOS, voltage is 1.040 and cache is 1.296..... I currently have it set at Adaptive and the offset to Auto which I'd like to continue to use unless I can't undo what BIOS 1102 did...I was quite happy with 46/46 and max voltages of 1.408 to 1.424.....if I can't get back to where i was ......then I will fiddle with individual numbers.

BTW, I assume you meant 0.05 not 0.5 in the quote below smile.gif

It might be that Vrin/ Input Voltage is not set right. Than this error can happen. Experienced this with an I7 and I5 sometimes.
Solved this by testing different Vrin voltages.
What stresstest did you use for stability testing ?

Thanks for the response. I'll check when I get home from work and report back.

I will try adjusting them. I believe I am using 2.05 as Vrin

I used x264 and XTU

I have a i7-4770k and I followed Intel God's Quick & Dirty 4.4Ghz overclock tips. Right now I am at 4.4Ghz and at idle I am 32C. Ambient temp is 22C.

Here is my setup:
Case: Node 304
Cooler: NH-U14S
Mobo: Asrock Z87E ITX
Noctua case fans
OS: Win8.1


OC Settings:
CPU Ratio: 44
Cache Ratio: 35
VCore Voltage: 1.250
CPU Cache Voltage: 1.22
CPU Input Voltage: 2.00
Fan Speed: Full On
Everything else on AUTO.

I have run intelburntest on very high for 10 tests and they all pass. I am able to boot into Win 8.1 without any issues. However when I run IBT it initially spikes up to 100C for a bit then goes back down to 71C. Is this something normal or do I need to bump up the Voltage on something?

Also the GFlops I only get about 104, is this normal as well?

One thing I noticed is that when the temps hit 95C+ is when the CPU clock goes down to 3.2G and load is 99.9%. Is there a setting in the BIOS that I need to modify to keep it at 4.4Ghz? I did the registry hack to keep all of the cores to not be parked.

I believe the frequency is dropping to 3.2ghz because 95C is the throttle point of your chip. Once your chip reaches are certain temperature, it will throttle down in speed to ensure the chip isn't doing damage to itself

You can check my max temps on the first page, with 1.25v.
95C is a very high temperature, it's not a surprise you would throttle. You might want to stay out of there if you can.

This was only seen when running Intelburntest at very high. I would probably need to crank up the voltage to get it to be lower temp though from reading through the first page it isn't surprising that I hit that temp on air running that synthetic test. I will try prime and x264 to see what I get. I also need to use hwmonitor to get some more info. Thanks.

What stresstest did you use for stability testing ?

Use bluescreenview, it'll tell you error code even for a lot of restarts that didn't show BSOD - if it's 124, i'd add 0.01 vcore, might happen on edge with VRIN too but i didn't see that myself yet

I do read bluescreen codes, but this happened to me always when I was close to right Input voltage. Last time I had to up Input voltage by 0.01, could pass x264 but a Prime test would fail. smile.gif
