I have the same mobo and CPU and recently just did a round of OCing it, so I could probably assist if you need further help.
You can change multis in windows via one of the OC tools in AI suite (some like "turbo EVO" or whatever - I don't really use it much, although it seems to work fine...
I wouldn't worry too much about it. Unless you reach a critical threshold where it literally kills the CPU as you are watching even extreme voltage needs some time to do anything significant. While 1.5 is definitely too high for Haswell for actual use, in all likelyhood it is still a ways of...
as troubleshooting id suggest grabbing ubuntu live or similar which you can run directly from an usb stick or cd at boot wi4hout any actual installation.
the idea here is that by doing this you get to remove all of the potential problems of software (and harddrive issues like Ide-ahci...
Well, short status update:
I tried my hand at OCing via offset(+). It didn't take me long to find a good curve that seems to be stable at both idle, light and max load (prime blend).
I'm blend stable @ 46x100, LLC medium, actual Vcore 1.432-1.440, idle around 1.000-1.050'ish (hard to get exact...
Hey all,
Can anyone suggest how I can log my Vcore somehow? (not just record min and max, as any single buggy reading overnight will frack that up). It would be a useful thing to do in order to optimize my offset-based OC.
Unfortunately google is really giving me nothing on this... :/ Only...
You can't tell if a CPU has been overclocked or abused (or even used - unless there are marks left by the cooler on the heatspreader), so forget about that.
That said, in my experience, CPUs either work fine or not at all. I've yet to even see a half-defective or severely degraded CPU...
Happy to help. I hope it turns out to be that simple :)
It might help you to google the specs for your RAM. usually you will find a cryptic set of numbers on a sticker on the RAM (usually close to where it says its rated speed in Mhz). Googling that number should find you a document that...
For the i7 you are paying extra for the hyperthreading + higher stock speeds.
The hyperthreading is a nice feature to have for scientific numbercrunching, encoding, videoediting and the like - heavy predictable "work" workloads. For games it typically either does not have an impact or (rarely)...
If its turning OFF (not crashing) then it could potentially be several things, but its probably not overheating (unless the heatsink has literally and no longer has contact with the CPU). Bad memory also will usually throw a BSOD error, not a system power-off, but I suppose it doesn't hurt to...
One thing that comes to mind - when you get loads of seemingly random BSODs with no consistency to them then memory is very often a cause of the problem.
The new CPU you got has a higher FSB (1333Mhz) than your old one (1066Mhz). Make sure that your memory is set up accordingly. Normally if you...
I do have VCCIO - which from what I read "boosts the signal from CPU to the memory" (in very laymans terms), so based on that it seems like it could be relevant, but I also read about it that stock values should be more than sufficient up to 2000++ Mhz memory (and I'm only running 1333Mhz), so I...
Memory checks out (5-pass memtest at stock, best I know to test it at least)
No trouble blending at stock (or at lower multiplier / higher Vcores)
So it does seem to me that it is the CPU that is having trouble - but the question is just if there is anything other to do about it other than...
Better i just link you the manual than trying to list everything:

see page 73
A lot of things like uncore I don't think really exists anymore on these (relatively) newer systems. I don't think I've seen any...
Nah, my memory for sure doesn't have an XMP profile. It's Kingston value - so best left at stock =P I'm not sure if this generation of motherboard implements XMP in any case (I can't remember having seen it - but then again I haven't messed around with memory, so I might just have missed it)...
Thanks, I think my understanding of the function was just fundamentally wrong. I envisioned that all data fitting into L2 would stress it more (because it never had to wait for anything to continue operations), not less (because it didn't have to work with the memory interface as well).
I got...
I'm not really suspecting any defective memory in any case (these two sticks have been in regular use for a few years and not given me any trouble as far as I am aware).
Of course my memory COULD be defective despite me not noticing anything wrong AND 5-pass memtest failed to detect anything...
Small update:
Ran memtest (5 pass) at stock. All ok. I think we can regard memory as problem free.
Then tested the tip from the tomshardware post about lowering DDR3 frequency. It had no bearing on stability whatsoever as far as I can tell. Also gave a shot to boost the VCCIO a bit - but...
Thanks flexy - im running a memtest on stock just to be absolutely sure first before I proceed. I'm 99% certain there is no issue since this is not a new system and I've stability tested my lighter overlock (on a shitty cooler) before, but it doesn't hurt to make doubly sure. Gonna let it run...
I'm going to run an over-nighter small FFT stability test first and foremost to ensure that current settings are solid for that task (I've run over an hour already, but 8hrs beats 1hr for making sure) - then I'll give vccio another try I guess. I have tried messing around with it a little...
No, my BSOD is directly related to the blend testing. I'm not really going into regular-use testing until I have it prime stable. I hear some users had issues with 124 BSODs when in mostly idle, but that's related to not using a manual voltage and stuff going wrong when it jumps between...
Hey all
I have a question regarding stability testing for a 2500K on a P8Z68-V pro (basically same stuff as the normal P68's).
I'm shooting for prime stable daily use setup, and my CPU seems to easily go to 4.7, maybe even higher) but above 4.6 I'm having a hell of a time trying to get the...
Yea heatpipes are supposed to be resistan to this and even be able to work against gravity - but it must have some effect. Noctuas own manual says the heatpipe-bends pointing upwards is a bad idea (and some reviewers who skimmed the manual recorded bad results from mistakenly mounting it wrong)...
Hey all,
Since I recently got hold of a proper CPU cooler (NH-C14) I'm trying to squeeze a little more juice out of my old 2500K on my Asus P8Z68-v pro.
I'm trying to find if there are any good OC guides availiable. Obviously there are plenty for Sandy Bridge CPUs in general, but it would be...
The NH-C14 is a "blow down" design though, not a tower cooler or similar, so there is not really any way to direct the exhaust with this. It's going down no matter what (you have some small control over what parts of the motherboard will get a little extra side-benefit cooling, but that's about...
Hey all,
I recently got my hands on a NOCTUA NH-C14 and I wanted some advice on what orientation mount it in for optimal performance, as apparently this cooler (and many heatpipe coolers in general) are greatly impacted by which way gravity pulls on them.
The manual states that having the...
Hey all,
As I'm sure some of you know the Samsung HD204UI had a problem with bad firmware that lead to the disk creating unreadable block on the drive. I experienced some minor data corruption before I became aware of this - then I updated the firmware with a new version that is supposed to fix...
