Slightly mis-worded is a bit of an understatement!

I know. They said I'd get it today but I haven't had any notification from DPD so it doesn't look like it

Hope you didn't have to take leave to wait for the delivery. One time I was waiting for delivery of a bed and had to take a day off to receive delivery because their delivery window was something like 9am-4pm. In the end, the delivery was postponed to another day! Wasted a day of leave for nothing.

I've had that happen before when I was working. But now I'm a full time carer for my mother so I'm in all the time apart from now as she fell and broke her hip so that m on the way to the hospital now. Just hope I don't get back and there's a card telling me they couldn't deliver it. But since I've had no notification of a delivery I'm guessing that it will be tomorrow

Sounds like a tough situation. Hope she's able to recover well.

Hopefully. I'm only a mile away from the DPD when at hospital but 20 when I'm at home. Hope I don't drive home then have to come back

Got an email at 17.15 saying it's been shipped so will be tomorrow

seems like the repair has worked (although havent clocked it to 5GHz yet just at 4.9) max temp in cinebench 68 and prime which ony ran for 10 minutes with 1344FFT was 75

greenbrucelee · 10 Aug 2019 at 00:51

yep as I type core 0 29 core 1 29 core 2 30 core 3 29 core 4 30 core 5 29. Core temps not jumping around as much either

greenbrucelee · 22 Aug 2019 at 20:36

can confirm everything good. Clocked to 5GHz at 1.34v idle 28-30 depending on room temp AIDA64 cpu stress test never get above 68c after 2.5 hours, No failure on multiple runs on Cinebench also hits 68, OCCT hits 75C but passes but heres the odd one Prime 95 v26 temp never gets above 75 but it blue screens after 1 hour 55 minutes

Personally, I wouldn't consider that stable. I'd continue to tweak the overclock settings because I'd rather have a slightly slower clock speed, but with the peace of mind that it's more stable. Just my own preference though.

I'm not sure what else I can tweak apart from vcore. Maybe I will try upping it.

Try Vcore 1.35V to see if that helps stability.

It fails at 3 hours in prime with 1.35v and 1.36. I dont think I did well in the silicone lottery

However 4.9 does not fail

I was thinking if doing my fan curves would help any

At the moment I have the cooler set to 50% at 34c (it idles around 29/30c apart from tonight which is quite humid and is idling at 33/34) then I have it at 55% at 58c, then 61% 65 then because of how asus doing things anything past 75c is 100%

an0nym0us said:
I would just leave it at 4.9MHz. It's only 100MHz difference.

yeah am doing. Not sure why it fails at 5GHz as temps never go passed 80c. Have done several tests on prime and blue screens with a different error every time.

Mine needs 1.35v to be 100% stable at 5ghz. It will run lower but with the odd crash in any application.

I seem to not be able to go past 4.9

an0nym0us said:
The thermal limit hasn't been reached, but looks like it might still not be enough voltage for that frequency. Assuming it's stable, I'd just leave it at 4.9MHz and not worry about it any further.

Yeah I'll just leave it as it is.

can you confirm load mhz speed and max core voltage after a cinebench 20 multicore run ? i would use hwinfo and coretemp. post the score here.

go into bios and confirm llc setting.

doing an avxclock offset might be what
you need if the chip is not strong enough at 5ghz avx. there is a more complex method of using a voltage offset for avx if your board has it.

sorry for not replying been busy

load speed is 4901 and 1.34V llc is level 6. I have tries with speedstep on and off and also windows power management at high and balanced, AVX have tried 2 and 3

greenbrucelee · 5 Sep 2019 at 10:30

1.34 is what I set it. It hits 1.36 in cinebench

greenbrucelee · 5 Sep 2019 at 10:30

Max temp 80c

Besty said:
that's not bad you know. if it was hitting 110c at that voltage then yeah, you have a problem but at 80c it all checks out imho.

Yeah I can't figure it out. 4.9GHz can run prime all day with 1344fft at 5GHz it runs 3 hours before BSOD and it's a different error every time
