There's still hope for 47x biggrin.gif Not as a 24/7 i feel (1.37vcore is fine for me at the moment, i'l see how the 1.5v guys hold out in 3-6 months) but as a solid bench profile for at least non-HT tasks/games.

I was just wanting to see what your values were under prime95, I'm fully aware of Vcore and llc and sensors being a little off. That is going to vary from motherboard to motherboard, what seems to be the same is very high temps with everything fpu intensive. People are claiming some very nice clocks but not alot of stress to back it up. I can pass 12 hours of the x264 custom test at 16 thread at 4.7ghz 1.4v, but 2 seconds in prime 95 it will throw a rounding error. At 4.6 1.368v I can do anything including prime 95 blend and IBT (temps hitting 90C on one core) but 4.7 will throw a rounding error all the way up to 1.45v. It seems core vid is lower when somebody has a good clocking chip, say 4.7 at 1.35v. So i was hoping you could run prime 95 blend for at least 5 min with HWinfo open.


I don't like this whole my chip is stable at 4.8 but in reality its only stable in 1 program. I understand not liking high temps but if you cant run prime for more than 5 min stable then your overclock is not really stable at all.

I'm stuck at 4.6 as well, I dont think many people are truly stable above 4.7-4.8. Looks like that is the wall with skylake.

The chips seem fairly consistent. I seemed to hit a wall but i think it was just because i had fclk raised, i tried to keep pushing forward with RAM at high clocks and i had manual forced values for SA and IO volts. Something was messed up with my settings because it became crazy unstable with only minor tweaks from profile that seemed rock solid. Without that stuff, it's probably just a matter of voltage. Sure it might take 0.05 - 0.075v for 100mhz but you can still scale, it will just kill the chip if you keep doing it. It seems like i could get 4.7 with HT working 24/7 with a chip that seems slightly below average, it would just be using edgy voltages. Temperatures would still be like 70c max lol

I'm running a Gigabyte Gaming 5 board and I found that I got greater stability running LLC on High. My 6600K couldn't hold 4.6GHz with 1.4v with LLC on auto, failing aida64 and prime95 in minutes, but with LLC on High I'm getting 4.6GHz to run at 1.36v fine. With LLC on normal or auto, HWinfo and AIDA64 were showing drops in vcore. With LLC on High, it still drops but only a little. (ie. bios vcore set to 1.34v, LLC High = 1.344v in idle and 1.332v running custom x264 16T). I assumed with LLC on auto, there was to much vdroop during load and it was causing failures. Should I go back to LLC Auto or Normal instead of High?

Also, whats the best C-state settings on the Gigabyte board? I currently disabled all c-states and EIST, except c3 state although I'm not sure if this is even helping with stability. When I have all the c-state and eist settings to auto, my chip runs few degrees hotter in idle then with only C3 enabled (25-27C vs 29-31C). I put my minimum processor state to 5% in windows so the frequency drops. VID drops as the frequncy changes but V-core stays still, never dropping. What to do? This gigabyte board is giving me a headache.

I did 1 hour small ftt of prime 28.7 couple page back at 4.8 ghz + one hour 1344k and a least 2 hour x264, did also 1 hour 1344k at 4.8 with low clock cache @ 1.37 you can see the picture in my prev post , but I did not claim stable, Im not even on the chart yet , im still tuning things.

Not my fault if my chip hold better than your... its not because your cannot hold 4.8 with decent temps and voltage that everyone else cant...

anyway here your 10 minute blend test of prime 28.7 , @ 4.8 core /4.7 cache /3200 ddr4 / 1.395V ( set in bios) LLC High

LLC on auto is the same thing as "Normal" and its mean OFF

there only 2 setting of LLC on our board , ON-OFF

Its all about the voltage with LLC, check my previous post with my Vcore reporting LLC on and off

I keep the LLC on high for now but im aware that when bios is set a 1.395V im hitting near 1.42V for real under prime 1344k , I guess the 8k test will report even higher vcore.

Is there any software I can use for stability test at the load of "typical office work" ? AIDA or Prime are overkill for what I need know...
post #2440 of 11361
Okay so I started from the ground up and my chip will do 4.5 on 1.3v prime blend with stock everything else. If I bump cache to 4.5 and ram to 2400 I need 1.31v. 4.6 looked like it needs 1.4v+, I guess I'm going to run 4.5 until I figure something out, or other people have better results. Is there any hard proof on 1.45v being safe vcore besides a quote from some guy saying asus stated 1.45v?
