Wow, awesome efficiency!

I was going to, but haven't quite figured out what limit to use. 4.5GHz is easy, so memory should be more challenging. But maximum memory clock is just function of the maximum possible BCLK.

How it the clockgen implementation on that Asrock board? The clockgen integrated on the P67 is not the key problem. Even on the most recent P55 boards, the clock generators have strap setting to run at 400BCLK (~ P45/X48). The problem is that this the clock generator is locked to 1:1 thus running all components at the same base frequency. Therefore, increasing the BCLK equals increasing the frequency of all the components on the CPU package (eg: USB, PCIe, DMI, ...). The LGA1156 Lynnfield and Clarkdale architecture is a lot simpler in terms of clocking. I'm pretty sure that Asrock implented the P67 as simple P55+Clockgen+extra features. As said before, the type of clockgen Intel integrated in their P67 chipset is the same design as we've been using on P45, P55, X48 etc. It's not strange that Asrock manages 200+ BCLK.

Antinomy - Everything integrated on the CPU as well as integrating a single clockgen into the P67 chipset. The problem is that everything within the CPU package is running at the same BCLK, much like in the past we had no control over PCI/AGP clock frequency so everything runs 1:1. The clockgen Intel integrated in the P67 is a normal CK505, very similar to what we had on P35/P45/P55/X58. That type of clock generator actually has 'straps' build-in, meaning Intel should be able to open up dividers for this platform where necessary. Perhaps we should hope for a mainboard manufacturer to reverse engineer the P67 chipset :-). As far as I understand from reports on the LGA2011 platform, they will be integrating the dividers in the next platforms so BCLK is fully open again.

The BCLK limitation is a 'feature' of the Sandy Bridge technology. Unless Intel provides workarounds, I don't think we'll see much more than 110.

No.

Hm, interesting! I'll fire up the board tomorrow.

For the Maximus IV Extreme, you can try this: - set everything in bios - save settings - hope it goes through --- if 63: quickly power off/on PSU and just boot again (repeat if necessary) - boots up 75% of the time with 'overclocking failed' settings -> F1 (bios), don't change anything just F10 (save) and reboot again AE is indeed when loading the drives. It's also a sign of the max of your CPU; you can work around the AE and get the boot menu, but OS loading will fail because the all cores are stressed. Also, I often have issues booting >1.55V vcore For P8P67 Deluxe, Don't use bios profiles to save you clocks, it didn't work properly here with the PLL bios. I could get the highest clocks only with clear cmos and setting everything manually. Loading a bios profile returns 63 all the time.

Coming soon

Not bad! Batch?

CPU-Z Memory tab is mandatory by HWBOT general rules.

It's not as bad as a sticker on the PCIe connector

No CPU-Z memory tab. General rules say this is mandatory: http://hwbot.org/rankings/benchmark/maxxmem/rules

Okay, added

Fueling the hope that random numbers will enlighten us on the overclocking capabilities. Also, providing justification for spending money on yet-another CPU by the 'it should be good'-argument.

For your information, you can also see the # of the CPU if you look at the sticker on the box. The last 4 digits of the S/N are the same as the ones on the black sticker on your CPU.

I'm sorry for the confusing - Stage 6 of course

Just added one extra rule: validation date must be later than January 8th (announced limitation: 9th). Reason is quite simple: we don't want old scores to be used

Submission unlinked from Stage 2 because Ikozarov already uses this memory kit for his score: http://hwbot.org/community/submission/2100416_lkozarov_maxxmem_ddr3_sdram_2295.4_marks

Just went over all results for stage 1. Removed this score because the incorrect background was used: - http://hwbot.org/community/submission/1096946_ All other scores look fine! Done.

No competition background
