April 20, 201114 yr Author First impressions: solid board, 222 BCLK on Air with pretty old C0 Core i7-920 set directly from BIOS to OS and SuperPi 32M ... later will test with Core i7-990X and some cheapest Xeon under LN2 ... BCLK Buttons really works, but not with higher BCLK then 220 MHz ... maybe problem of old bios? Problems: Plastic pins on VRM heatsink - bad contact with mosfets! Plastic pins on High-end board? No actual Voltage readings in BIOS ...
April 20, 201114 yr Problems: Plastic pins on VRM heatsink - bad contact with mosfets! Plastic pins on High-end board? No actual Voltage readings in BIOS ... Pics of plastic pins? no actual voltage also on p67a-ud4 lol
April 20, 201114 yr Pics of plastic pins? There is multiple pictures about those white plastic pins in the first post Thanks for posting OBR!
April 20, 201114 yr BCLK Buttons really works, but not with higher BCLK then 220 MHz ... maybe problem of old bios? Had board up to 253 with buttons.........also did a you tube of bclking on the fly in 3d to show limits of 3d benching at 234/235. 014 bios. Edited April 20, 201114 yr by chew*
April 21, 201114 yr Author ive played with only one hour, have to test today better, btw what is your PCI-E for that high BCLK?
April 21, 201114 yr ive played with only one hour, have to test today better, btw what is your PCI-E for that high BCLK? Board seems to like 112. Tested with 3 bloomfields to 248 @ 112, high limit seems like 120 hard drive dependant, needed for 250+ if you are booting these speeds like I am. Edited April 21, 201114 yr by chew*
April 21, 201114 yr Author better now, but which disk are you using? With my SSD it seems as a max ...
April 21, 201114 yr mechanical WD's. Gonna have to drop to slow mode soon 1 or 2 bclk more. Won't effect 2d.
April 23, 201114 yr Author look at this video: Strange BLCK fluctuation ... BTW. Oscilograph screens added ...
April 23, 201114 yr this makes such a nice base for lots of marketing CPU-Z validations True but that is common for 920's at an unstable QPI or uncore........ I can do same on an asus with a clarkdale and have........ It's up to the overclocker if he chooses to submit a bugged result.
April 23, 201114 yr look at this video: Strange BLCK fluctuation ... BTW. Oscilograph screens added ... GIGABUTT stability there LOL... thanks obr
April 23, 201114 yr There is multiple pictures about those white plastic pins in the first post Thanks for posting OBR! ok just saw the two plastic pins... i guess thats hicookie's choice? or gigabutt's? lmao
April 23, 201114 yr Author Its not bug with wrong BCLK only in Cpuz, but this BCLK fluctuation is REAL! Look ... BCLK was 235 x 21! ! ! Real screenshot: Bugged screenshot: Result is higher, BCLK has to be a 235! but is higher for real ... not only in Cpuz ... Something is wrong with that OC controller on board ... this CPU under air, cannot to reach 262 BCLK and 5,2 GHz Edited April 23, 201114 yr by OBR

Something is wrong with that OC controller on board ... this CPU under air, cannot to reach 262 BCLK and 5,2 GHz Doubt the speed is actually higher, just because Aida thinks it higher and scores better doesn't mean its actual. We have seen similar trends with other benches. maxmem for instance can be exploited by raising AMD's NB multi in windows.........but the reality is it actually can not be raised. However the benchmark still reflects higher scores becasue it thinks the clocks are higher. My guess is certain benches can be impacted and certian ones can't.
April 27, 201114 yr that bclk problem is as old as x58 - happens on any board around the bclk limits...
April 28, 201114 yr ive seen this behaviour on just about every X58 board i tested, asus, evga, gigabyte etc etc. As SoF said no news there X58 chipset going wild a little when at the limit
April 28, 201114 yr Yep. I demonstrated this on my RIIIE. It happens when the board reaches its QPI limits:
April 29, 201114 yr funny you can still validate lol, i can't believe you thought i hit 276 lol. I hear that the bug is a bug yes, but its for real i actually hit 276blck for a few milliseconds and then done. But its not something i will submit as i feel it is partly cheating. I have seen this happen on other non GB X58 boards in other threads, make you question some of these insane high blcks even with minor testing. Anyways i feel as though this board is built for gulftown much more than bloomfield. i like the plastic pushpins, easier to keep track of, my contact to MSOFETs were fine.
