Awesome

Dino magic or UP7 magic ?

 

lol or just magic

 

got a video with 7.2+ GHz

If I have all of the subtimings set manually and I can boot with 102.54 BCLK and 26.00 multi (2666 effective), I should have no issue booting at 100x26.66, correct?

 

Because that's not what's happening. I can't boot with a multiplier higher than 26.00. BIOS F6C.

 

EDIT: Booting at 106x26.00 for 2756 effective... but I still can't even boot at 100x26.66.

 

EDIT 2: Pushed as far as I could in Windows... 109.5x26.00 = 2850. Of course when it froze, it caused a cold boot. It wouldn't even boot at 105x26.00 anymore. To get there, I had to start with the BCLK low and slowly make my way up (101x26, 102x26, 103x26, etc.).

 

Here is the full array of settings. Everything is quite loose:

 

BCLK 100

Memory Speed 2600

CPU Vcore 1.35

CPU VTT 1.15

CPU PLL Auto

IMC 1.15

DRAM Voltage 1.65

Read Slew Auto

I did some refresher reading and realized that the only thing I left on Auto is the slews and apparently those should help. I'll mess with them later tonight when I get back from work.

[xxbassplayerxx]

WOOOO!!!! GO Slew rates!!!!

 

 

Booting with 29.33 multiplier

 

Slew 2 did 28.00 multi, slew 3 does 29.33

yup slews are magic on that board haha. Also different multipliers also apply different background timings that the end user can't change. Also different multipliers use either 200mhz or 266mhz and that can make a difference.

[Vi0lence.]

i tinkered with my board to get it over 2666 with my avexir memory and it wasnt happenin. i just gave up on it. idk why.

[xxbassplayerxx]

Did you try the slews?

[Vi0lence.]

yea. tried a bunch of different things. always seems to just not take. i can up my bclk a little, but nothing serious until it crashes. i know this is holding me back too. just cant seem to figure it out.

[xxbassplayerxx]

What are the timings on the Avexir memory? 2666 10-12-12? Or 11-13-13?

[Vi0lence.]

11-13-13-35. anything i try to do other then xmp it just doesnt do it. sucks. i mean even my old dom platinum dimms got up to 2133 without anything other then a few tweaks. this stuff wont budge

 

unless its just my imc.

[xxbassplayerxx]

What do you have the IMC volts at?

[Vi0lence.]

now its all back to default. just have a mild clock on it. i forget where i brought it up to. what would you reccomend putting it up to? i also never lifted the ram volts over 1.65v due to them being on air. could be part of the problem.

[subaruwrc]

can I get high bclk in the orange pcie slots?

or the black only?

its missing from my board
