At least yours boots at 4.6

Not much good if I can't put any load on it

Mine wont boot at 4.6. I am simply saying there is worse.

 

[EarthDog]

Pretty sure i've got a shitty CPU

I haven't played with it much more than this, I tried 46x100 and 1.25 and it will boot but any load crashes immediately.

1.25v? Grow a pair and give it more volts! 1.25v for 4.5Ghz is a good chip really. So..... MOAR volts!

 

[TheHunter]

Btw, how much does System Voltage Agent - Vccsa help by overall stability?


mine now with +0.150 is at 0.960v., and appears to help by lower cpu voltage, but temp. stayed around the same (1-2C lower).

This passed Cinebench 15 multi test @ 1.262v 4.7ghz.. Idk if it will pass all.. I need 1.28v to be stable in all atm .


edit:
It bsod in Re5 variable test.

Vccsa 0.190+ offset makes 1.09v and cpu at 1.269v fixed it (reports as ~1.268v), still a lot lower then 1.28250v (started at 1.289v, 99% stable)..

Is it safe to run at 1.0-1.10v? for example 0.200+ starts in yellow (1.15v?).


EDIT2: I returned to default value, got higher temps. even though I used lower cpuv.

How long should i run AIDA64 for i did 5 minutes on 4.4Ghz 1.2v.

Whats classed as a good or bad chip I'm at 4.5Ghz still on 1.2v set manually.

Try running FPU test only in AIDA there. if it passes THAT @ 1.2 V and 4.5 GHz, you got a great chip.

 

[Kursah]

Note: the FPU only test is extreme and will generally hit the 90's or even peg out 100C...at least that was my experience with air cooling. But if it passes, it passes. The CPU is hurt by voltage...it throttles at 100C..by pretty small increments in all honesty, I think by 100Mhz increments...which at 4500mhz isn't shabby at all. This is my findings with my fairly expensive air cooling solution during summer weather though. But it hit the 100C mark very fast.

It just crashed my system on the 1st go the 2nd go it hit throttling like 4 seconds in dam these things cook, I guess its not 100% stable ill drop it down to 4.4Ghz and try again.

I dont think even on stock i can run this test what does that say my H100i isn't working right how does a CPU get that much heat in so small amount of time.

Can any one tell me that they can do the FPU test and keep there temps under 100C ? Mine jump up to 100c in less that 5 seconds but on a normal stress test my temps dont over over 65c.

Me?!!

 

[LiveOrDie]

Is there a problem with my chip then? My temps are fine on normal use games and programs.

What cpu voltage are you using?

-auto
-manual fixed
-manual offset/adaptive?


I hit mid 85-90s with adaptive offset 1.278v >> 1.367v, it climbs to almost 100C later though.. At fixed voltage its a little better.

I dont run these burn-in tests anymore, found other tools like x264hd bench, geekbench3, cinebench, fritzchess benchmark and cpu games that are more stressful on whole system.


And yeah exactly why bother if its ok in normal apps, programs..

 

[vega22]

i dont either but the fpu tests get it hotter than most other tests.

i did, i would end up being throttled if i went over x43 but since i delidded it the temps have plummeted.

60c@4.5ghz now.

 

[LiveOrDie]

I was thinking about delidding did u just use normal paste and is that on fpu test? Im on manual voltage 1.20v temps 95-100c .

 

[petedread]

Got a new 4770k, this one is happy as a pig in s##t doing 4.5@ 1.200v, cache 4.5@ 1.100v, CPU Vrin external override @1.650v. Max temps after 9 hours OCCT are 65c. My first 4770k needed 1.310vcore to do 4.5ghz! And would hit 95c in no time. Very happy, will try for a higher clocks when I get a day off work. My target will be a maximum of 1.275 vcore as I have good cooling, so 1.275v should be fine for a 24/7 OC with offset vcore. Oh and at the moment I'm using a standard LLC.
Hopefully I'll be able to validate at 5ghz but you never know, just a 200mhz boost could require another 0.100v with Haswell, or at least that's been my experience.

 

[petedread]

Something I've noticed is that even when using offset volts for the cache, CPU-z shows that the cache clock doesn't drop when idle. Is this the same for everybody else?

 

[EarthDog]

The cache does not drop, correct. Just vcore and speed.

 

[cadaveca]

Is this the same for everybody else?

Nope, on some boards, it's dynamic. Tell me, is it stuck @ 35 or 39?

 

[TheHunter]

Yes depends on the mobo

I have these options:
min cache - auto
max cache - auto
it will run at x39 all the time.

If I select
min cache - auto
max cache - 43
it will run at x43 all the time, if i config. min to x35 it will drop to x35 in idle/voltage.

Also with all c-states enabled (c7 and package state) it can drop to low 0.4v even at min x39.

 

[petedread]

It's stuck at 4.5.

 

[cadaveca]

It's stuck at 4.5.

As TheHunter posted, sometimes choosing other cache options can affect if it's "locked" or not.


Either way, nice chip to get 4.5 GHz CPU AND cache at those voltages. I'm quite jealous, actually.

I really like the look of that gigabyte BIOS.

 

[petedread]

@MxPhenom 216 the gigabyte bios does look nice but unless you get one of the OC boards you won't have as many bios features as the asus boards.

I've just noticed that I wasn't using a offset on the cache so I changed it to offset and now it's crashing after 20 mins of OCCT. The cache clock still doesn't drop. I have all C-states on auto. I'll try turning C-states on to see if that drops the cache clock.
LLC won't help with the cache will it?
I may have to add v to the Vrin as I add v to the cache

 

[TheHunter]

Yeah 1.10v @ 4.5ghz looks amazing

Set it to adaptive voltage, by total adaptive "turbo voltage" put in your final voltage ie 1.10v, by offset - auto.

Im using adaptive and I need 1.11v for x41 , x44 already 1.165v, but I use all 4 ram channels dunno if that makes any difference.
