Winners for the "most interesting" Score have been decided. We also decided to add a second kit to this prizepool - a triple kit of 1060 6-7-6 SR sticks on KO-8154. The winner of the "most interesting" category is @looze with his custom bios https://hwbot.org/benchmarks/memory_frequency/submissions/5831717 Second place is @ProKoN with his 1669MHz triple channel valid - higher then what I anticipated possible, and even without the uncore mod by looze. https://hwbot.org/benchmarks/memory_frequency/submissions/5821234 More details on the voting and point distribution here: https://docs.google.com/spreadsheets/d/1gD1DSQqEC5kxGYEa7lRc03wOpwlRqUnHF1D9L3Y5LCU/edit?usp=sharing Winners will be contacted in the coming days or can contact me or @TAGG themselves if they are in a hurry ;)

and yet, best bloomfield uncore beats best westmere uncore (edit: well, I can’t test my uncore unicorn Westmere on core since its max 16x core multi, but it does >4.9GHz uncore on water)

the fact its full ambient makes this even more impressive 👍

The best board is banned for a reason https://valid.x86.fr/d2bhzw x58a-oc allows proper desync memory, though people are working on figuring out whats going on so other boards might allow the same at some point

the platform can run way higher clocks then this, it being still in triple channel is whats mightily impressive. Also the fact its on Asus and not gigabyte

I suspected <14s was viable but I absolutely did not expect it to drop this early into the comp! (sorry accidental doublepost)

I suspected

dammit, now I really have to swap boards :D

Found a couple batches that are very reliable at reaching those settings 3918A497, 3914A740 for i7 920 3918A533 for Xeon W3520 3914A739 for i7 975 (my best is 4500 1.23V, but it “only” does a bit over 5.5 on cold sadly since it has a bad coldbehavior - for this batchrange - of -130 sweetspot. My W3520 is happy at fullpot and my other 975 (5.8 valid) at -160.) QR code range for these chips is N3924-N3926, with almost every single chip I’ve found or heard of in this range being 4500 <1.25V and most chips easily doing 5500 on ln2, as long as bclk plays along. looking at LN2 results and old forum threads I’m fairly certain W3570s of these batches certainly exist too, unsure about W3540. I’ve tried finding a 950 for years in this range but without luck. Since I’ve stopped actively looking, I no longer feel like its right to keep this info to myself.

For comparision - the 920 chip Luumi benched - the second best core I’ve found - needs 1.205V for Superpi 32M at 4500 MHz. My W3520 is slightly better (4500 1.19V), but sadly bclk limited. Said W3520 does 4.83 at 1.33V on air and 4.9 at 1.35V on water. On cascade these chips scale absurdly well, 5.5+ at 1.45V or less (with typical scaling of 0.04V/100Mhz this would mean ~5.0 at 1.25V ish, maybe even less given these are scaling well above average and voltage wasn’t minimized on cold.

well thats a proper strong IMC! Lovely clocks and solid score!

If anyone has issues with CPUz 2.15, you are not alone. Without any changes to the OS, its not showing changes to BCLK. Given that clocking up after boot is relevant for memory frequency, the followinng fixes have been found: for modern OS: bcdedit /set useplatformclock true for legacy OS (win XP): edit C:\boot.ini and add "/usepmtimer"

The rule was added specifically with SR-2 in mind to avoid dual socket scores for ycruncher. Given it would be run as single socket in that case, I don't see it breaking the spirit of the rule, so sure.

with these boards you can literally grab some dead 1366 chips, throw them in, pass post once and they will work again in other boards as well. I've done it 2-3 times with DOA Bloomfield chips (I still have no idea how people manage to kill bloomfield), Luumi managed with a couple 32nm ES chips as well iirc. The chips seemed to behave perfectly fine afterwards (had one i7 920 that did 5.3 multicore but still BCLK limited from this trick, core felt good for 5500+ given behavior)

Woah! Thats a proper record! Shows the possibilities with these new tools that have been appearing last couple years for older platforms. Keep pushing!
