X5675 Overclock Settings

[FivePointOh]

I set up a 4.25ghz overclock on my X5675 but every few hours I get a IRQL NOT LESS OR EQUAL bsod... I'm sure it's not the core voltage, since it's using less than 1.32v and I have it set at over 1.33v. My ram is 1600mhz, so I don't think that's the problem either. I don't know what it could be. Anyone have any suggestions? Temps are fine btw

Overly high QPI or Uncore?

[FivePointOh]

Well the board and cpu are both good for 6.4GT, I'm not sure what that is in ghz though. Should I maybe try dropping my multiplier and increasing the bclk? That would drop down the Qpi right? Because I already have the qpi multiplier set to 36x and the only slower option is slow mode...

 

Anyways here's what I'm getting on HWinfo...

Assuming you have tried increasing your voltages already by a little bit and no fix, then you should try decreasing the multiplier and increasing bclk. You could also try Slow mode for QPI, it's really just testing things and seeing if it works.

I tried lowering the qpi but the qpi multiplier is already at its lowest setting so yeah I'll have to try just slow mode and see if that does anything. 

 

Does anyone know of some working settings to get a 4.5 OC on the x56-- CPUs? Preferably on the gigabyte/award bios layout. I want to see how different the settings are and maybe it'll show me what I'm getting wrong. 

 

This seems to be a really good x5675 specimen and if I can't even take it to 1.35v then that's kind of a waste...

 

EDIT : qpi slow mode is 84mhz lol... The computer posts but it's so slow I don't think it would ever get to windows. It was posting before, though. Just not stable. I think I'm going to call it quits at 4.25ghz because it looks like there's nothing I can do to fix the high qpi.

I don't have the images handy but search for my posts in the X58 overclocking thread.

 

I have a Gigabyte UD3R, X5675, and OC to 4.5ghz for everyday. Have gotten stable at 4.7 but was welllllllll past diminishing returns at that point.

 

But, basic way to do it is to be VERY patient and only modify one thing at a time. Figure out how high your BCLK will go (and what voltages it takes) with everything else turned to low multiplier. Then figure out the same for memory. Then CPU multiplier.

 

It took me a good 6+ hours to step through BCLK to find my components' stable sweet spot (215 MHz, ~1.35V iirc), memory at 8x or so multiplier, and 21x CPU multiplier at ~ 1.35V. I think I tinkered with other voltages, can't remember.

I just tried the settings that TechYES posted on his youtube for a 4.5ghz OC, and it worked no problem. Going to run AIDA for a few hours, and then decide if I want to risk my mobo and cpu to try and push for higher or not. I probably will because soon I'll have enough saved up for a BRAND NEW 9th gen intel system (CANT FKIN WAIT)

Feel free to push them pretty hard, CPUs are cheap. I push 1.45v through my X5670 (it was $14), planning to push around 1.58-1.6v and see if I can hit 5GHz. I am on a custom loop though so I have a lot of thermal headroom. I've seen people claim they ran 1.66v daily for 4+ years but I haven't confirmed that.

Link to that video? I've been running 4Ghz for a couple years and wouldnt mind a higher daily.

Did you still need some tips for OC the x5675?

 

you get higher gflops in intel burn test if you disable hyper threadiing. 6 cores is way more than enough for games, who needs 12 virtual cores.

 

make sure the uncore is no more than 2x the ram mhz. In my experience leave the ram at 1600 and set uncore to 3200.

 

qpi set to 6.4

 

start at 200mhz fsb x 20 multiplier and run a intelburn test, then go to 21, 22 etc. mine tops out at 22x200 = 4.4ghz

 

disable the usual stuff like clock spectrum and disable turbo boost.
