Isn't haswell more BLCK friendly than pure multi?

It has straps so you can run higher BCLKs, but it still has the same limits as Sandy/Ivy around those straps (+/- 5% or so).

Thanks for the Cinebench comparisons, there is a fair difference @ 4.6G

Thankyou for the video, I am still peeling myself off the ceiling after watching that stanley knife go in under the heatsink.
If I find the need to de-lid, I reckon I will definitely go for the Vice/Block & Tackle method.

The work you guys do on here is amazing and incredibly helpful to overclocking newbies such as myself.

Enjoy the new rig smile.gif

I changed a couple of settings in the BIOS and it's been 5 hours since I started Prime95. No crashes yet so I'm crossing my fingers. I don't remember the stuff I changed and I gotta get some sleep so I'll report back in the morning.

I get a lot if 124 (CPU watchdog timeout) errors as well - sometimes settings that were perfect stable will suddenly become unstable and cough up a lot of those, for some reason. I kind if wonder if something else is going on there.

Changing the VRIN seems to make a difference, at least as far as booting into Windows goes. And I tried using an offset for Vring and that seems like it may have made a big difference. I need to mess around with it more tomorrow to see if it helps consistently. That's the real problem I have - it doesn't seem like just increasing Vcore helps the way it normally would - seems like there's something else holding it back. I also want to try splitting the VCIOA and VCIOA the way Asus recommends.

after skimming through this thread my 3570k becomes more decent by the minute biggrin.gif (it's good for me and other sandy/ivy owners but bad for the industry that slowed down advancement)

But you can't over blame intel for this, since the OC market vs the whole desktop haswell market is small. and even within the OC market the majority won't really push beyond that.

(my theory: Intel might have intentionally or partially intentional capped the Ghz because of the VRM's on the CPU. unlikely but not too far fetched.)

I've been saying this for weeks now the best chip to me right now anyways, a delid 3770K..

Cyclops - can't thank you enough bro..

Hopefully there is more to OCing these. Seems to be a pattern of 4.4Ghz stable max.

Kind of points to the right CPU voltage control not being increased. Is there a setting for the IVR or something like that? It's like everyone is stuck at their max OC on stock voltages.

Anyone tried OCing with the CPU ratio instead of the Turbo ratio to see if it helps.

Would like to see some BIOS screenies of all the menu's if possible.

Has anyone else had erratic temperatures with any type of overclock.

I've delidded and bare die mounted my 4770k. I have a very good custom water loop with a raystorm block.

I've only had about an hour or two to test out overclocking, but my temperatures fluctuate 10-15c in 1-2 seconds. The highest I've seen is mid 80s with a fairly high vcore at 4.7ghz with no throttling, but it concerns me to see temperatures fluctuating like that.

Any advice would be appreciated.
