Intel Haswell Overclocking Clubhouse.

Cool, so you're fine at 42x cache @1.075v? I never tried that low yet

Here are my specific default timings


And I noticed the same read/copy drop at 2200mhz.. Weird stuff, thanks Cadaveca for that extra info.

Actually that 42x cache was just while running/benching Cinebench. Later I was testing with HyperPi 32M and I found it was not fully stable... Freezing and or BSOD. Now running 45x/41x vcore (+.80) and cache (1.10v) which completes HyperPi 32M... with a Cinebench score of 9.95.

I'm finding HyperPi 32M to be pretty good for dialing in and testing cache/imc settings.

Thanks for the suggestion, I'll try HyperPi. I'm trying to stomp this random BSOD, if I could just get it to consistently fail on something. It hasn't happened since I bumped up all non-core/cache voltages: VCC-In = 1.85v, VCCSA +0.1v, VAIO +0.1v, VDIO +0.1v, DRAM 1.55v.

@ Womper

This generation chip seems quite "squirrely" sometimes?? It makes me wonder whether I might have pushed things a little too far voltage wise... But to be honest I don't really think I did anything too aggressive while learning/testing on Haswell. I've uninstalled AISuite III and I'm going to do a fresh Windows install before trying to push clocks and memory some more.

 

[TheHunter]

I tried 2400mhz, ram ratio 100:133 and CL10 but it just doesnt want to run so good like 2133mhz

Write got a nice 5gb/s boost, but read and copy still below default..

Mobo auto loosen adv the timings a bit, but its not so big to make such a big bandwidth diff., no?

So the best would be to use 2133mhz and raise Blck until I reach 2400mhz?

I am having BSOD issues with Crucial Ballistix Tactical 1600mhz 8-8-8-24 BSOD when XMP enable. I am not sure if its isolated to the motherboard

Yeah, when I get a bluescreen it seems to be more likely to bluescreen the next boot, until I get it stable again with conservative settings. I believe I also saw this behavior with Nehalem, although with Nehalem it only bluescreened on bootup maybe once in that scenario, and then it'd clear up. With Haswell, sometimes it takes 4 or more attempts to get stock settings and DDR @ 1600 to not blue screen at the Win7 boot logo.

I was wondering if I had pushed it too much also; with a 0.225 offset, voltage goes to 1.45 during AVX loads. I just hit it with prime95 for a few seconds just for fun, and throttled instantly.

So you swapped the memory out to clear up the issue? And in what situations does it BSOD?

I am not sure if the actual memory is bad. I was having increasingly stability issues, no overclock only enable the XMP profile. I decided to reformat and was unable install windows errored out at 73% I removed the crucial memory and was able to completely install. I am using Gskill right now with XMP enabled and overclocked

 

[Grnfinger]

I see you finally have things up and running, nice specs.

yep, just learning the bios and all it's settings
Hope to push the overclock a little further this weekend

 

[Womper]

Solved the startup BSOD issue. The blue screen flashed so quickly I could never read it, but I finally caught it with my camera: it's a 0x7B stop error that occurs due to an inaccessible boot device. Surprise! I have one of the affected old Sandforce SSDs as my boot drive! It seems as though it gets aggravated when I tinker with BIOS settings.

With that mystery solved, I can focus on the 0x124 that still randomly pops up even when I'm not overclocked.

Change VRM settings for your board from "Thermal Balance" to "Current Balance". VRM is probably overheating.


Just figured this out with another user today, 0x124 that only happens at stock, using a watercooler. With other user, other coolers worked fine, but there were air coolers.


Didn't you get an H220 or similar recently?

Batch#: L316B291 4770K on a G1 Sniper 5.
With my limited knowledge and experience I have currently got 4.3@ 1.216v temps peak at 83c but hover around 75 in Aida 64. Pretty much everything on auto. I have played with some different settings a little bit a few days ago. I think I had something like 4.4Ghz with 1.250v and my old Samsung green at 2133, 1.5v and 10.10.10.26 1t. The temps got to high though. I need to get into more detail with the cpu volts but I don't know what any of the settings mean in the bios, like, what is
K OC?
CPU PLL selection?
Filter PLL level?
Looks like I haven't got a bad chip but it certainly isn't as good as some of the chips I 've seen on other forums. I need almost 1.4v to get 4.5/6ghz and the temps go up to fast.

 

[cadaveca]

K OC?
CPU PLL selection?
Filter PLL level?

K OC adds some multis to non-K chips. Dunno how well it works, maybe good.


CPU PLL Selection choose where the BCLK PLL is sourced from, CPU, or the PCH(chipset). Filter PLL level should offer "high/low" options, again, for BCLK. These are more for ram clocking, since you can get most any frequency at CPU with multis and minor BCLK OC.

Check the 4th post for the stuff we're looking for to try to figure out if a chip is good or not. If you can give all those details, that'd be great!

I believe I observed this BSOD when I was using the Zalman hsf, but it would definitely make sense. But, I haven't seen a BSOD since increasing input, SA, A/D IO, and RAM voltages, so it might just be that Auto voltage rules are too low on one or more of these. I've been at 4.7GHz again to maximize my chance of BSOD, need more testing before I call it done.

And this H220 is pretty nice- with a more reasonable ambient temp of ~70F, it didn't throttle during 1.5 hrs of Aida64 with core @ 1.374v. Idle temps were at 21-25C- can't beat that.

Also- can one of you who owns a fancier motherboard tell me how cache voltage varies using an offset? Does voltage jump up and down depending on idle/load/AVX load?

 

[cadaveca]

Does voltage jump up and down depending on idle/load/AVX load?

Yep, and multi scales with it too(unless you manually change minimum multi). Haven't seen AVX loading make a difference, but I was not really looking. I'll keep an eye on that though, let you know after I work through a few more boards which might give me a chance to see if it is or not, or maybe some boards do, some don't...

 

[petedread]

Some screens just for you guys. I don't know how to see what my cach is running at, at the moment so I'm not going to be added to the list just yet. But maybe this info could be useful.
Batch#: L316B291 4770K on a G1 Sniper 5.
4.5@ 1.332v, Corsair H70.
Samsung Green, stock 1600mhz. OC'd to 2133mhz 10.10.10.27 1t. 1.500v
100.00mhz base clock. Everything else auto.
Aida 64
Temps to high at these volts to use this oc. But it boots and runs Aida for as long as I dare.

your cache is the NB frequency in the second screen shot.

Lol cheers.
4000mhz, so if, for example, I'm running the CPU at 4.5ghz and having stability problems, I could lift the cach to say 4400, from what I've read somewhere.

 

[Grnfinger]

I fail to post if I push my ram farther than 1866

These sticks are supposed to be able to handle 2000MHz easily

 

[cadaveca]

Seen anyone do it with Haswell and those sticks? Memory clocking on Haswell can be rather unforgiving.

yes 2 sites have this kit running at 2000+
I'm still learning the bios so I hope to have it nailed down this weekend now that the work week is done

Are you using auto cpu voltage? Because 1.33v for 4.5ghz is overkill imo. I bet you would need max 1.20v.


Gigabyte is known to overvolt top much by auto cpu voltage, I had the same problem with my old Gigabyte x48-DS5. I saw another user with similar Gigabyte z87 mobo reporting the same, he was at default 39x and 1.25v.:shadedshu

 

[petedread]

No, I'm manually dialling in the CPU volts. After days and days of reading and falling asleep at the computer I think I have started to understand what most of the bios options are for. So I'm about to go back into the bios and try a few things. Although I think I have just got a poor chip.

 

[v12dock]

Turns out my memory is actually bad. Tired on P55 computer and still blue screened I will have to RMA

 

[Grnfinger]

I have these sticks
http://www.ncix.com/products/?sku=76775&vpn=PV38G186C9KRD&manufacture=Patriot

Can anyone recommend some better choices for clocking. I guess I got some dud's
I have 200 to play with

 

[crazyeyesreaper]

Just a bit of info from my testing it seems Heatpipe coolers on Haswell perform better depending on the orientation I need to do some more testing

but heatpipes oriented left to right works better than up and down.

so on a traditionally mounted motherboard = is better than ll

so far this has been true on the Argon AR03 and Hyper 212, the AR03 i saw about 2'C drop Hyper was only 1'C drop but it was a constant and held after multiple tests. Depending on the cooler results might be better or worse. Ill have more info later.
