Very nice. so looks like msi isnt the only one that can hold a really high bclk. :DQuote:

No, its with my EK Supreme... but i have no LGA1366 mounting plate and now is not enough pressure
Those are still reasonable temps for improper mounting :DQuote:

How are you liking that Gigabyte board? Are you adjusting thru windows with EasyTune? or using bios settings?
Board is nice, first i had some problems but Core i7 is different overclocking than Core 2 :D
I use ET6 to show the voltages, i set all voltages and clocks in bios (i changed only the vcore with ET6)
ah yes this time the GB boards defenitly rock, UD3 pays off. :D
I'm looking seriously at the EVGA board. Jakup has a stable 4.3 clock on that board! On air! :eek:
Now saying that I probably wouldn't try that for awhile, but these guys are able to get some serious OC's on all of these top boards. These rock. I'm sitting here dying a slow death until the 17th when I will be reborn hard! :D
I'm getting this. I'm not 100% set on what I'm getting, but I will be by the 17th. I just hope I can get the ram for it.
Reaaaally nice. 1,20v 3600MHz stable :D
I've one question Chri$ch, is there any way to make the CPU lower its voltage at idle when overclocked?
Is it possible with any of the boards out there? The Intel Smackover board has an option in the BIOS that says "Dinamic voltage override" or something like that, I guess it can be used to achieve this goal. Can anybody confirm?
Does BCLK overclocking afflict only the mobo and CPU or does it mess with other components ?
very nice, is there much difference between the ud5 and the extreme apart from the heatsink and waterblock on the extreme ?Quote:

AMD

Memory = BCLK x mem multiplier/divider
HT link speed = BCLK x HT multiplier
NB Clock = BCLK x NB multiplier
Intel FSB
BCLK = 133, 200, 267, 333 (evolved over time as FSB speeds go up)
FSB Clock = BCLK x 4
CPU clock = BCLK x multiplier
Memory = BCLK x mem multiplier/divider
Intel with QPI
BCLK = 133
QPI clock = BCLK X QPI multiplier
Memory = BCLK x mem multiplier/divider
CPU clock = BCLK x multiplier
PCIe bus, for example, is timed with it's own clock gen, so it is unaffected... but the core components all time themselves from a common system clock, which is what BCLK represents, when you read people write "I hit 215 MHz HT clock" or "I OCed my phenom with a FSB clock speed of 215 MHz" ... the technical meaning is they adjusted BCLK from 200 to 215.
Also, the "uncore" (L3) powered by VTT to mess with and if you don't have the XE chip and have to raise the BCLK too much above 133Mhz to get your best oc, you could run into problems with QPI depending on the board (or so we hear). With XE, you can leave BCLK at 133Mhz and just raise the cpu multi for a maximal cpu oc. Guess that makes oc'ing the 920 and 940 more interesting, or at least requiring more skill.
Indeed, going to the AMD-like point to point interconnect comes with it all the nuance challenges of raising the base clock for locked CPUs.Quote:

Yes! - and I'm not convinced that the best oc's on the XE will come without raising BCLK above 133Mhz.Quote:

Obviously going above that spec is OC'ing and is done at the user's own risk.
Do some searches. There is lots of info scattered around about this.
Thanks, I only intend to run them until the 1866Cas8 Tri channel kits hit the shops here.Quote:

I was just confused by Chri$ch saying he had no memory to test it with, when he had a P5Q3 Deluxe a while back.
JEDEC spec for ddr3 is 1,575V max. (1,5V +/- 5%) ;)Quote:

I need 6x2gb ddr3-1600 cl8 sticks, but none available. :D
I plan to keep those at least till sandybridge. Maybe then switch to 1.35V DDR3 1600 :p:

does ET6 works in windows? (eg. can you adjust the voltages in windows with ET6 realtime?)Quote:

yes it works, you can change all voltages, CPU multiplier etc :)
nice, saves a lot time. :D
