Crosshair VIII 2501's for testing

[uplink]

So, in general 2701 work, but I can't set D.O.C.P. in BiOS/UEFi nor FCLK to 1900 MHz, nor any other custom value :/

When I set D.O.C.P. memory profile, the system won't post. But overall performance is good, WHEA Error-ring has dissapeared [2402 did a LOT of WHEA Errors, like 300 per few minutes].

Tinkering with 2701... Right off I notice higher core voltages. nearly .1v more. In turn the higher voltages is impacting temps, and finally clocks, being 100+Mhz off in all core loads, Like CB20 or Handbrake. While running all core, voltages are nearly 1.3v. It doesn't seem to degrade the benchmarks though seeing another 100pts on CB20 for instance. Which makes me wonder, what is the relationship of the Frequencies we're seeing all core, to the actual benchmarks. Why would the frequencies in HWInfo all show lower, but provide a better benchmark number? Its curious.

"Tinkering with 2701... Right off I notice higher core voltages. nearly .1v more. "
This behavior corrected after a bios reset... no longer overvolting on its own....

Hey there @Shamino,

So besides 2402 [which works so so], the 2501, 2502 nor 2701 wont even post for me with my settings [that I use on 2402].

This is my current post error on 2701.

07 is likely memory timings. May want to work on secondaries, or increase CAS one clock. May also need to increase SOC voltage.

I'll try both and will report back, thank You!

Going from 2 to 4 dimms 3600 c16 19 19 39 would i need to increase any voltages as I'm just getting random restarts in lightly threaded loads no blue screen

[Riplex]

With new 2701 still random freezes with restarts. Back to working 2402.......

These are my settings [in short]

These are my settings in full, shot only what I've changed.

And I'd like to ask last but not least question. Why don't we Formula owners have the "Performance Enhancer" option in BiOS anymore? I mean in some older versions it was present, now I don't see it :/. There were four levels, level 1 - level 4, now it's missing. It's suppose to be in Extreme Tweaker between FCLK Frequency and Core Performance Boost option.

Thank You and I stay with best regsards

I had that error when trying to clock my 4x8Gb RAM to values they couldn't reach (but they did with 2206 version).
Other tipical errors where "LOAD VGA BIOS" or something CMOS related I can't now remeber.
Try to leave timings to Auto and see if it improves.

Tonight 12+ hours of RAM testing with 2701, everything is fine... but I'm nolonger on 4x8Gb.

My system was absolutely fine till I went to 4 x 8gb. I get shut downs without any error as if the system suddenly loses power and restarts

[Riplex]

With 2402 i get also restarts with default settings. ^^

Going back to Agesa Patch B with 2311..... Hope that works......
