post #18221 of 19603
You know, someone has to be at the very end wink.gif no offence. I will post back what my 4690k will do. Most probably I will not even hit x43 as I have MSI B85I mITX.. :/

in all those extra asus bios settings it feels like im missing another setting besides volts.

im getting around that extra setting by forcing more volts but i bet there is a different setting that would allow me to reduce my volts and change the other extra setting instead.

1.3875v for cpu at 44x?
that is the highest there is in that chart for that multi. (if i submitted my restults that is)

Is this the same 4770k that you used to get 4.6 @1.3v, then messed up delidding it?? In your previous posts you mentioned stressing it at 1.4 volts and repeatedly hitting 90C while using the onboard video. I think you hay have done some damage to it trying to get the "most out of it". If that is the case, there is no ammount of BIOS tweaking that can fix it. Sorry mate.

dont think this is the same chip.

yea this different chip.
the chip i messed up delidding was a great chip.

this one has always been stubborn but i think its a good chip in a bad chip disguise.

it runs stable 4.2GHz @ 1.275 and also stable @ 1.3875 for 4.4GHz

i have always felt there is some other setting that has to do with "POWER" or "Total Power" that is limiting it somehow.

what is the setting for upping (the part of the cpu that talks directly to the memory)?

im betting its that intel memory controller that really needs the volts and not the ia cores or cpu vcore.....

certainly someone knows the settings besides just vcore/vrin/ia core....

there are tons of asus setting in DIGI Power + etc...

4.2@1.275 is not good numbers or promising.

You can try upping ram voltage, or IO digital/Io analog which is probably what you are talking about. But these are only going to help you once you hit the voltage wall at a high overclock, to eke out the next multiplier. If you're at 4.0@1.2v you only have a few multipliers above that regardless.

I think you are talking about the ring voltage. That is the voltage provided to the uncore. Your uncore has your on-die memory controller in it.

here is a video of the bios settings im talking about concerning the "external digi power" area for my motherboard (Asus Z97I-Plus)
at the 3:30 secs you can see he goes into that area on the video.

https://youtu.be/L_OO5SLKxhk?t=210

it could be ring bus or uncore im not sure.

all i know is 4.2GHz seems high @ 1.275 and 4.4GHz @ 1.387v is also high

i seen in the video i linked above hes at 1.35v "adaptive" for the cpu @ 48x
(must be nice)

anyhow at 3:30 into that video is the area im talking about.
i think for alot of bigger boards with more voltage phases that those settings could probably be left at default but since mine is a smaller board with less phases maybe i need to adjust something in that area?

idk
the computer boots fine at less voltages it just wont pass stuff like linx or ibt or p95 where it uses lots of memory.
my ram is not high end memory and is pc1600 @ 1.5v
i read when increasing the cpu frequency it automatically adds more volts to the IMC and that if there is a voltage gap of over 0.6v difference between that and something else that it is not good.

do i need to set my dram voltage (1.5v) higher when i do not overclock my ram? i just leave ram at ddr3 pc 1600 in bios and @ 1.5v default

anyhow i feel i shouldnt need to push that much volts into the cpu for 4.4ghz when it boots into windows 10 and seems fine except when i do memory intense stuff.
anyhow do i need to adjust any of the stuff in the digi power area at 3:30 into the video since my board only has 6 phase power design?

For overclocking Haswell, unless you're running a high memory OC, you really only need to mess with the Vrin, VID, and cache voltages. There is a delta of about 0.4-0.6 that should be maintained between the VID and the Vrin.

Have you read the guide on the first page of this thread? There's a section that talks about this....

yes i have read the guide on the 1st page and read the part about the 0.4 diff.


no that is not what im talking about wink.gif

i read that by overclocking haswell with the cpu multi atumatically applies more volts to the imc (if i remember correctly) and that the difference between that and the Dram voltage setting should not be greater then 0.6v

hmmmm i could go try and find the spec but i think its from something that looked like the intel haswell data sheet if i remember correctly.


those special settings i linked to in the above youtuvbe video...
anyone mess with that area or the digital and anlalog IA/IO or whatever its called?

dont forget i dont have good ram at all.
pc 1600 1.5v

it just seems like the wall on this chip isnt the cpu area where it does its calculation it seems like the wall is on the memory controller side

in the very beginning of the video he has his AI Tweaker settings set to Manual and Adaptive cpu voltage

my bios setting is set to XMP profile and i select do not use asus overclock thing at that time.
i usually only set cpu multi 44x, vcore 1.3875v manual and my vcin = 1.9v

what would be nice is if you guys update to your latest bios and take a small tour of your bios settings your using on your haswell (with your phone) and then upload it and say your ram and cpu.

i guess my question is does the raising of the cpu multi freq increase the voltage automatically one one side of the imc and therefore would need to raise the dram voltage to stay within the 0.6v?
have you ever had to raise your dram voltage to complete ibt or linx when not overclocking your ram and overclocking cpu with cpu multi only?
thanks


i think i find a link to what im talking about

Really, Intel is very spec oriented, JEDEC originally called for 1.5 on DDR3 (and also took DDR3 ONLY to 1600), Intel calls for DRAM voltage and MC (memory controller) voltage to remain within 0.6 of one another...At stock 1333/1600, the CPU generally run a MC voltage of slightly under 0.10 depending on the mobo...when OCing the the CPU the MC voltage rises allowing also for higher voltage DRAM... I myself won't touch sticks 1866 or lower that run 1.65, or 1600 running 1.6....2133 is about the sweet spot for DRAM at 1.6 to 1.65, though lower is still better, and it has no ill effect on effectiveness if the sticks are slected and set up correctly

Yeah, cuz what do I know with my 4670K that I put up to 4.7ghz (when its colder outside), and my RAM OC'd to 2133mhz? You must be right, carry on.... Trying to help you get past the point you're stuck at.

I'm trying to tell you that those voltages you're focused on don't come into play unless you have a high memory OC, like 2400+. The 0.6 delta doesn't apply to the RAM voltage, it applies to the VRin and the VID.
