All right, might as well start overclocking this thing...

 

...god damn it. 4.2 GHz at 1.25 VID is doable. 4.4 GHz will need at least 1.35 VID thus far in my stability testing. Already have some 82c load spikes with IntelBurnTest 2.53. (Gotta update my toolbox of stress-testing apps...it hasn't changed much since my Q6600 overclocking days.)

 

At this rate, 4.5 GHz and up will be well beyond what my water-cooling loop can handle. Argh...

 

...well, what do you know? BSoD during extended IntelBurnTest. 1.35 VID STILL isn't enough for this bloody thing. Perhaps there's something I'm overlooking in the numerous BIOS options, but this is looking pretty terrible.

 

4.4 GHz needed at least 1.36V. 4.5 GHz needs upwards of 1.4V, and I don't feel like pumping that much into my CPU.

 

This sucks. How are you people getting 4.6-4.8 GHz on 1.25-1.3V?

 

And, yes, before you ask, I set the cache multiplier to x34 and RAM to 1333 MHz to prevent them from possibly bottlenecking things. Also set manual voltage, not adaptive voltage.

 

*goes back to 4.2V and drops it to 1.245V, tries Prime95 for a change, gets BSoDs even at 1.25V* Oh, damn it. This is going to be even harder than I thought.

Soooo DXTory still isn't working...

Needless to say, I'm pissed off. The GTX 480 seems to have a serious VRAM problem now, and putting the HSF back on hasn't helped matters. Something tells me it all went horribly wrong when I decided to put the waterblock back on. Argh.

 

On top of that, the GTX 280s I have in storage are completely dead (no video output), which means the only working PCIe graphics card I have around is that old 8800 GT, which happily runs in the new computer. So much for your joking theory.

 

NVIDIA better bring out Maxwell quick, because I can't stand 8800 GT performance for long.

Yea that's computers... there are a dozen things that might be screwing with ur OC. I actually never got a BSOD when I OC stock air for 4.01ghz. I might try for 4.2 or 4.1. I don't want anything crazy just stability up and around 4ghz honestly. With my new CPU heat sync I'm gettin idle temps around 30c so I'm getting closer to trying for a stable 4ghz oc my self... maybe

If you get 82c spikes I feel like you must have done something really really wrong...

The stupid screws for my HDD broke in half when I was removing them. Now I only have one in the top right and one on the bottom left. Screw you, Enermax. I'm eventually gonna buy the Fractal R4 and use the hard drive brackets.

I really like Fractal cases. You won't be disappointed.

They have the plastic HDD bracket things that you snap onto the drive and just slide in right?
post #3219 of 9059

Does any one here have experience "un bending" cpu pins? A friend might be sending me an 8350 that came with bent pins and AMD nor Newegg will accept a return.  I expect it to be a PITA but as long as I'm patient and careful...... worth it for a free cpu upgrade :biggrin:

 

Not sure if anyone is familiar with popping the anti-reversal latch on airsoft gear boxes w/o opening them but I expect it to be on the same level.

I think they use metal ones on the Define. I can't remember.

There are many things that could be holding you back other than main cpu core voltage.  Specifically the memory controller, try bumping the memory speed down a few steps and see does that improve the cpu overclock, then try more volts to the memory, memory controller bus etc.

 

Also keep an eye on on the bus/memory clock speeds as you overclock, depending on how you are adjusting the cpu speed you may also be increasing other bus speeds at the same time.

 

For example on my 3820 i ran into issues in the low 4ghz range due to memory multiplier, by dropping the memory speed i was easily able to get the cpu over 5ghz.  My final setup was 4.6ghz core @1.295v, and 2ghz memory.  I could get the memory up to 2300mhz, or the core upto 5.1ghz, but not at the same time, key was finding the balance between the two.  interesting when i found the sweet spot i was able to bring the cpu core voltage down which = less heat.

When it comes to PSUs, I like using this site for checking out good PSUs: http://www.realhardtechx.com/index_archivos/Page541.htm

 

I was recommended this site by a thread on Tom's Hardware, and I will admit, it is glorious.

How bent exactly exactly are we talking?  I've ran into the issue a very long time ago, but I can't for the life of me remember which CPU it happened to.  if its not bent too badly (like completely clumped together at a 90 degree angle), it may very well be salvagable with minimal effort.  If its just a few pins then you'll most likely be good to go, just have to be very careful, obviously.

That's just the lottery dude, bad luck on that chip.

 

My 3770k isn't the best either, I need to get around to delidding it one day, but I can't be bothered because I'm pretty happy on how it's performing (in other words, I have low expectations =P)

 

I'm at 4.4ghz @ 1.20V, I'm using offset/adaptive voltage because there's not much point to setting it at manual constant voltage, it's a waste of electricity IMO.

 

I hit ~93C on LinX/IBT (ambient around 25C), I can't quite remember how hot it got in BF4, I think it was only 65/70C ish. I'm using a D14 for cooling.

 

The temperatures don't bother me one bit, life's too short to lose sleep over CPU temperatures. A few hundred megahertz isn't a big deal, don't stress!

You think the memory controller's being stressed at DDR3-1333 rates already? I have my doubts...if we were talking DDR3-2133 or higher, probably, but DDR3-1333 with typical 9-9-9-24 timings is pretty conservative already.

 

Unless there's something else I'm missing, but I doubt it. My RAM's simply running at JEDEC spec for the time being. I'll probably put it up to DDR3-1600 or higher once I'm done with the CPU overclocking, though, because core is king.

 

I doubt I'm doing much to other bus speeds; I should also point out that I haven't even touched the base clock, just the multiplier/core ratio. Even though Intel brought back BCLK straps to Haswell, most people still leave BCLK at 100 MHz and work with the multiplier. It's much simpler that way.

It's so far below the apparent average that I'm honestly going to return it within a week. Might even step up to the i7-4770K if Hyper-Threading proves valuable for future games as well as video encoding and whatnot. I'd probably make out better on the chip lottery with just about any other Haswell CPU right now.

 

Next time...they say batch numbers don't matter much, but I'm making damn sure they hand me a Malaysian one.

 

Keep in mind I'm using manual voltage because I'm still stress-testing for stability, and adaptive voltage means a nasty case of overvolting while stress-testing. Once everything's finalized, I'm switching to adaptive.

 

Here's what I've managed so far:

  • 4.2 GHz (42x100) core, 1.25Vcore, 4.0 GHz (40x100) cache
  • 4.4 GHz (44x100) core, 1.365 1.37 1.38Vcore, 4.0 GHz (40x100) cache (STILL TESTING...crap, a thread failed on Prime95 small FFTs despite doing well on blend. Seems like that mode really does put stability to the test, and after 1.365V, it seems to be getting LESS stable. Argh, these 0x124 BSoD errors...well, if this is anything like Sandy Bridge, I guess I gotta do something about the low-power states.)

 

Temps are around 80-83c peak, so I'm not as thermally limited as most yet, even at these voltage levels. That water-cooling loop is paying off. I'm just limited by the insane voltages needed at this point.

 

I was planning to de-lid and go old-school, FC-PGA Pentium III/Socket A Athlon (XP)-style direct-die mount to really drop those temperatures, but this one just isn't worth it.
