Haswell Overclocking Guide [With Statistics] - Page 769

post #7681 of 19540
you guys ever get WHEA errors with haswell if a OC is unstable? specifically WHEA errors relating to graphics drivers?
post #7682 of 19540
Hello OC-heads,

I`m here asking for your help in guiding me on the path to my first stable overclock.

I have an i5 4670k currently at 4.2 Ghz, but not stable, 8Gb RAM Kingston HyperX 1600, GB Z87MX D3H mobo, and a 750w Silverstone fully modular silver certified PSU.

I didn`t win the silicon lottery, since my computer will not boot at 4.6 Ghz w/ 1.250V VCore.

Until last night, I didn`t knew that I needed to set the Uncore lower than the CPU clock , so I had CPU clock at 42x and the same for Uncore with 1.230V.
This was stable for 20 min of Aida 64 and Prime 95, but crashed in BF3. During testing didn`t get over 71C in Aida64 and 72 C in Prime 95 and 62 C in BF3.

This morning I reset bios, and went with 42x CPU clock and 36x Uncore, but still unstable.

I tried setting the VRIM on auto, and also at 1.800V manually, with the same results.

I also set the Turbo Cores at the same multiplier as the one for the CPU clock. And the CPU VRIN Loadline Calibration and Current Protection to extreme.
Also, I set the RAM to XMP profile, at 1600 with 1.65V, and selected Extreme Performance (I think I should have used Extreme Stability).

Since it`s my forst overclock attempt, I`m sure I`m doing something wrong.
Please tell me where I`m doing wrong, or what else I should adjust.

I will try to answer your questions to the best of my limited OC knowledge.

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.
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

What did Event Viewer say happened ?

My Bad smile.gif sorry yappp.. what i mean was 0.05 smile.gif

Btw i wanna share my daily settings :




4770k
44/44 (bios)
1.14v/1.15v (bios)
2133@2600 1.65v (bios)
Input voltage 1.880v (bios)

A boot on 1.25 VID @ 4.6ghz would be above average at this point. Based upon my chart, anyways. 

Your temps are fine. You did not specifically state what vcore is used for that 4.2 setting where you crashed at BF3. You also did not state if you found stable settings for 4.1.

It's possible.

I've knocked my OC back down 100mhz to try and rule some stuff out. I don't want to revert to stock since that won't be a real-world scenario for me, but if I run out of ideas elsewhere, ill do it.

To have peace of mind. I would put everything back to stock for now just to rule out unstable clocks. Just an idea.

My overclock is driving me nuts. I've been spending countless days trying to find a stable 4.7 but right when I think I'm satisfied, it fails a test. It's so random too, one moment it'll run through a 15 pass IBT on very high, then the next time it fails within the 3rd pass. IDK, I've yet to actually have it crash while using real world apps and have played several 2+ hour games of bf4 without a crash... so I'm pretty much done and calling it good enough tongue.gif

I got my I7-4770K to boot at 1.25 VID @ 4.6Ghz, even did a few burn tests with 0 issues. I tried to boot it at 1.22 and it was a no go. Will do more testing when I have the chance but I think this chip I got is from a good batch.

if you going to use 4.7 on daily pass IBT and hyperpi 32 is just ok ...
