Then I won't get Turbo boost though right? Hmmmm........

Splave 02-05-2011 12:57 PM

make sure
enable eist
disable c1e
enable turbo
disable OC stepping

Disable all cpu page options less eist. def need it for turbo

ny_driver 02-05-2011 01:04 PM

I'm pretty sure I had it just like you showed earlier Splave. Is the multi supposed to stay at turbo speed or 20 somehow?

QPI PLL a lot of boards do not have... when they do have it and it is not called QPI PLL it is called IOH VCCA 1.1v

IOH/ICH IO voltage is PCIE voltage. Some baords like EVGA link them. Some split it up as IOH PCIE and ICH pcie and some only offer IOH PCIE.

Sucks not everyone uses the QPI PLL because for me that had the greatest impact on BCLKing in my n00bish experience. (Then again the R3F didnt really need it, it would run up to 220BCLK on all auto settings :S) Higher it probably was needed.. I managed to hit an unstable 237 on it. But really anything past 222ish was unbenchable.

QPI slow link mode is only a good idea for CPUZ or if it allows you to jump to 5GHz. It seemed to have about a 7-8% impact on performance when I was trying the superpi 8M challenge a while back. (went from 1'30" to 1'35" IIRC). Try it I keep seeing people recommending it, but there must be something else to it then just enabling it.

I benched this @225bclk with 1.65 VTT....haven't really tested max bclk yet. Tomorrow for sure.

With this chip and turbo enabled for max multi....how do I get a validation when it jumps back to 12x while idling?

Load the cpu.

ny_driver 02-05-2011 04:27 PM

That doesn't seem like a very good idea when about to go for max cpuz.

Just noticed the little "XS Bench" button at the bottom of realtemp. It only loads the cpu @ ~13% for ~10 seconds. I guess that will work.

1.65vtt for 225mhz is too much...even 1.5 should work....im just guestimating..

GeorgeStorm 02-06-2011 12:33 AM

Yeah I'd say it was too much, haven't had the chance to test my 920 cold (probably won't as the board only does 220 apparently)
But I can get 200 at 1.34ish, so 1.65 seems very high.

Neuromancer 02-06-2011 01:34 AM

heh heh I thought I was a juicer :)

way to high a VTT for that speed. And if you are dropping to 12x multi disable EIST and CSTATES in the bios.
