Post Your Overclock!

[profdlp]

Thanks for posting. I wish more people would do the same. I think I will find them very useful.

Absolutely!

That looks like a great resource, smarteye.

After my previous post I just couldn't resist the urge to tinker. (And if I fry this sucker my grades will truly suffer... )

Anyway, so far so good at 48 X 100. Temps went down a degree, too.

For a small USB stick, there are no advantages formatting NTFS, and some drawbacks. Unless you need files over 4GB, there is really no reason to format NTFS. NTFS will also wear out the drive faster. A Guy

I never heard that one - that NTFS will wear a jump drive out faster than FAT.

There is also exFAT, which can have cluster sizes up to 32 MiB and file sizes greater than the 4GB limit of FAT32 and is also supported on MAC. Wonder if that will work with the UEFI, I will have to try it.

NTFS is a journalling file system, which means that it logs changes, not just the end result, causing more writes to the drive. It also logs last access times for files, so even a read causes a write access. There can also be issues with removing the stick. It must be safely removed or you can lose your data.

It's my pleasure. It's the type of thing I find useful too and rather than wade through X amount of OC forums for that 'useful' post - a picture speaks a thousand words.

And since a lot of us have similar boards here, it's even more relevant.

And now that I know it's so damn convenient to do so, I'm more than happy to post any pics people want.

Absolutely!

Monkey see, monkey tinker - and this monkey has seen and tinkered

None of my settings will fry anything, so you're good there. The 5.2ghz settings are good for short burst tests, even with the mega vcore.

If anyone needs a hand fine tuning, feel free to ask.

Yep

Personally I find it's good practice to 'safely remove hardware' regardless of filesystem being used. Handy for when you forget what stick/drive is using what format.

OK, so I have a odd ball issue and Im curious if anyone can reproduce it with a i7 CPU.

Yesterday we were discussing OCing, and it seems these posts were lost. But Smarteyeball brought out an interesting point about HT, and disabling may get a higher OC.

I did try it, and for the record x51 at 1.4Vcore was bootable to Windows. X52 got me in Windows but would BSOD very soon afterward. highly unstable. more Vcore would likely stabilize, but my CPU look like its going to want 1.45ish or so at x52.



But, during all of this, I noticed something odd.

With a Normal Overclock ..
My IBT, my scores actually went UP without Hyperthreading.
I also noticed that If I watched my Task Manager during the IBT test with HT On, at 50% load it was touching 69-70C. Once it hit 100% load, my temps dropped to around 65ish ... this doent make sense to me.

I disabled HT, and the load and Temps seems to be in line (68C at Full Load), but Oddly, the actual scores GFLOPS went up by about 8-9GFLOPS without HT.



Running 3D Mark11, during the PhysX text though was a bit different. HyperThreaded run was a good 9FPS higher, which is something as I would expect.


At any count, wondering if anyone else notices similar behavior under IBT, or am I missign something obvious here.

I'm guestimating that the added latency of the virtual cores might have an impact on IBT's GFLOP count :huh:

Either way, welcome to the 5.2 boot club

 

[Wishmaster]

Meh .. just barely bootable. Got into Windows yes ... but not stable enough to even get CPUz (or in mu case evga eleet) open.

But you were right. At 1.4 a x50 Multi was quite unstable for me. Turning Ht off allowed the same result but at x52

Still, all things considered its not bad. Think 4.8 was my last good stable run within my personal vcore limit. Although it was a bit much for me as a 24/7 OC.

 

[Wishmaster]

Its like people that collect stamps. To many it seems pointless, but to them its a fun hobby.

Same for Ocers. Sure there may not be a huge advantage to it, but its fun to do.

Though I must admit, Im not as brave as I used to be. For example, on this build Ive decided 1.4 vcore is my limit. Period.
Used to I wouldn't care and would push it for it was worth LOL.

 

[Britton30]

Sweet has a point, I've never seen any performance gains in OCing. Getting a faster CPU or SSD I did of course. Lower latency RAM has helped too.

 

[Wishmaster]

I run MeGuis x264 encoder, and typically run it with quite high settings for best possible quality. Many are HD encodes as well.

In this particular scenario, raw CPU/RAM speed, and amount of cores available rules the roost. A good stable OC really does make a difference.

But I would agree, overall and for the large majority of things theres not much gain to be had.
There are a handfull of games out there that are quite CPU intensive (usually MT ones) where CPU speed can help alot. But there aren't very many.
And then a few bad ports where the OC can just help muscle your way through poor coding.

Wishmaster, nice overclock at 5.2. Congratulations. But to your poini. I have a 2500K and recently got a 2600K. The first thing I noticed was even with just a mild overclock of say 4.4 during IBT my Gflops were way down. That sort of made me wonder so I turned Hyperthreading off and the Gflops went back up. Sorry I can'y provide the technical reason, but I have read on several overclockers forums that if you want to seriously push an OC, you need to disable hyperthreading.

OH, and Sweet is right for the most part. These machines are fine for 95% the things we do at stock. But, some of us have a problem that makes us want to do whatever we do faster. The best reason I can give as to why is, just because we can. Sorry, but I just can't help myself. Besides, to many of us, computers are our toys. What good is a toy if you can't play with it?

Hmm, Seems like we lost some posts last night.

Though NTFS is journaling, and there are some more writes, I very much doubt it has any significant impact on the life of a jump drive. Any file system can have problems if not safely removed, but journaling file systems should be better at recovering from it. L:ast access time logging can be disabled, buit I also doubt that significantly impacts the life.

With a thread per core, there did not need to be any context switches between threads. With more threads than cores, there has to be context switches. Even though with hyperthreading I believe this switching is done in the hardware, it must have some impact on tightly bound CPU thread of execution. That is my guess anyway.

Upon request, here are a few of my bios settings at a small 4.2 Overclock along with CPUz.
The first 2 are the overclocking utility from within windows that will show most values, the second is CPUz while running INR.


These are bios settings

 

[Wishmaster]

Willing to bet with the 1.28 Vcore, you could manually put the multi at x44 or x45 and be A-OK.
The OC utilities tend to Overvolt a bit.

 

[smarteyeball]

Thanks for the pics Steve.


Vcore under load is fine. But the spike up to 1.320 with the + offset and LLC setting might go partially toward explaining the high temps under IBT. The vcore is also a tad more than needed for 4.2ghz.

Your VTT is also a little low for a 1.65V RAM kit though. It should be @ 1.150, atm it's outside the .5 variance spec (bad for the IMC on the chip)

Raising the VCCIO/VTT also has the added bonus of sometimes reducing the need for a higher vcore.

You might be able to get away with lowering the DRAM volts a bit too later. So far, I've been able to get away with dropping it to 1.6v while keeping the same timings and frequency. But first things first

CPU PLL is okay @ 1.8v, but you could probably try lowering it. ie I can get away with 1.7025 at 4.6ghz. YMMV. (Max you want to see is 1.9v) Although it doesn't have 'that' big affect on temps.

Basically nothing is screaming "I'm overvolting" and "I'm the culprit" :huh:

Brings us back to square one....




I'll check back tomorrow with some fresher eyes and a clearer mind mate.


As an aside, one possible issue with your stability on your other board might have been the CR of the RAM being set to 1N. With two DIMMS, a CR2 setting adds a little more stability. Just an idea.

 

[Wishmaster]

Hmmm ... My VCCIO is at 1.05V as well. Should it be raised with 1.5v RAM?
Although Im not having stability issues was just curious.

 

[essenbe]

I tried some adjustments and passed IBT. Vcore just does not want to go down much it bounces between 1.172 to 1.280



But this is the problem and with this cooler should not even be close to this.

I know there are a lot of fellow ASUS P8Z68-V PRO/GEN3 owners in this thread of late. Thought I'd let you know that there are a couple new BIOS updates available. They are dated three days apart and seem identical, which makes me suspect there might be a compatibility issue with the first one. I haven't tried it yet, but the "Improve system stability" comment always sounds nice. (In theory, anyway... )

The Intel DC operating spec for VCCIO is 1.05 +/- a couple of percent and t hat is with 1.5V RAM, so you should leave it where it is.

There is also some issue with updating to 3202 as sometime the Intel ME firmware is not getting updated along with the BIOS. People were also reporting bricked 3101 updates. I would wait a few weeks as I believe they will have one out to fix the ME update issue by then.
