I don't want to touch BCLK at the moment so I'll leave C1E and EIST alone smile.gif

Prime95 Blend x45@1.35+PLL is goin on from almost one hour without errors.

 

So it's doing better with a lower core voltage?

I had bsod on x47 @ 1.450V+PLL
and test now runs on x45 @ 1.350V+PLL - this I'm leaving for night to run.

Then either the voltage was too high, or the temps were too high.  Regardless, it's fun to see progress!  :)

I've changed topic a bit since initial problem has been solved smile.gif

Overnight blend 8h without problems smile.gif 4.5Ghz @ 1.350V+PLL.
Now I will try to do something about BSOD and going for 4.8Ghz tests smile.gif

yay, so my estimates were right.

4.8ghz, will depend on your board to cooperate.

try

1.475v with pll

Already done:
1. 4.8Ghz @ 1.48V+PLL (I never get over 80*C, tried 1.45V and 1.475V all the same) - BSOD 124 at random.
2. Disabled all Cstates, little bit better, still BSOD 124 after few minutes of Blend Prime95.
3. hwinfo never show 1.421V top, never more with 4.8Ghz

So I suppose I can go with with 1.425V+PLL for 4.8Ghz, but I cannot get over BSOD 124.
What do you recommend to get over BSOD 124?
Should I up the VTT(VCCIO) voltage from standard 1.050V?

Hello all,
I think I found a new stable:
4.7Ghz - multiplier x47
Vcore 1.450V
QPI/VTT (VCCIO) - 1.050V
Turbo, PLL Overvoltage, C1E and EIST - Enabled
Multi-step Load Line (LLC), C3/C6 - Disabled

will do night test today probably.

I've read a lot about BSOD 124 and resolutions I found are:
  • Disable C states
  • Play with QPI/VTT (VCCIO) voltage

What do you recommend to get over BSOD 124?
post #38 of 66

Disabling C3 and C6 only works if you're using an Offset voltage with a very high Load-Line Calibration setting.  The BSODs that occur with C3 and C6 enabled (with a very high LLC setting) are when the system is idling, not when it's under load.

 

Also, 1.45V for the core voltage is extremely high for only 4.7 GHz.

It's a computer!

My guess is he has the high Vcore set because he has LLC disabled.

OP, is that 1.45 in the BIOS, or actual in CPU-Z? Try it with Multi step Load Line set to high and see if you can lower the Vcore.

It is in the BIOS, yes I had LLC disabled all time. Gonna try it now.

I tried on 4.8Ghz on Vcore 1.475V, bsod 124 all evening after 3 minutes in Prime95 each try.
I've worked all the way with PLL Voltage from 1.8V (stock) down to 1.62V, 1.60V gave me bsod 101. Also tried 1.84V which also gave me bsod 124, but faster - after minute.
Also tried all way with QPI/VTT (VCCIO) from 1.050V (stock) to 1.2V, didn't help.
Also tried chaning ram mode from Turbo to standard, didn't help.

After your post Forceman I'm testing 4.8Ghz now (1792 FFT test) on these settings:
  • Multiplier x48
  • Vcore 1.45V
  • Multi-step LL - Level 10
  • Everything else untouched.
and it's working ok, now it has been around 15 minutes, but I often see drop from 4.8Ghz to 3.3Ghz and voltage from ~1.420V to ~1.250V then it goes back up. Why is that?

PS: I've disabled C3/C6 in every profile, I've read it lowers SATA write speed.
