Am I to assume that non-MX CPUs don't gain a faster sustained overclock from an undervolt but instead get lower temps then?
At least until amperage and such is adjusted in XTU?
-
Undervolt still increases clockspeed in non-MX chips, but the key difference is the chip doesn't turbo as aggressively to make up for the "lost" TDP so overall temps are lower.

No, the IA Core Limit is something a little different. Use HWiNFO64 if you want complete information has HWMonitor is missing way too much important data. The fact that there is almost no change in the value is the first clue that the information is of limited value.
If you look at CPU Package Power with HWiNFO64 you will see a higher real-world number that reflects what the CPU is actually drawing under load. You will also notice that the wattage draw more closely resembles what you see ThrottleStop showing you in real-time when the CPU is under 100% load.
-
Sometimes there can be a pretty big difference between them, depending on what kind of load there is. I think the IA Core value may represent the most an individual core draws at time, but the CPU package power is what the CPU (cores, cache, memory controller, etc.) is actually drawing through its socket. There is probably something posted on the web explaining the difference. I generally don't pay much attention to the IA core power and focus more on what the CPU package is drawing.
-
Yeah my CPU package isn't drawing much but it's good to know that value is there for the next time I tweak the current limit.

Try pushing up the Processor Current Limit and that might help. My 4930MX idles at the clock speed I set it for and throttles to a lower clock speed if Processor Current Limit is too low. The key word is "limit" (as in capacity or ceiling) because that's what it is... meaning you can set it much higher than what you need because the GPU only draws what it requires. It's not a static value that gets pushed on the GPU. Same thing applies to the Long and Short Turbo limits.
-
What do you push your current limit to Mr. Fox? I lost all my XTU profiles when I wiped out my RAID the other day so I'm back at square one.

Yeah, it'd be something to try in the future here as well.

The exact settings that perform best will also vary by individual chip .
-
1.473v?! I think my laptop would self destruct at that point.
You got a really nice chip in that MX... My desktop 4770k won't even do 4.6 @ 1.47, it tops out at 4.5GHz at 1.38v.
Thanks for sharing your settings though, i don't think the Clevo could handle that type of abuse haha

I wish AMD could get their act together and come out with a part that actually makes Intel be forced to be competitive again
Sent from my HTC One_M8 using Tapatalk -
AMD has not made a respectable enthusiast CPU compared to Intel since the Pentium III/IV days. It would be nice if they gave Intel a run for their money like they did back in the early Athlon days, but I see no indication based on their past 6-8 year track record that they have any intention of even putting forth a half-hearted effort to produce an Intel-Killer CPU. I think they are too entrenched in a low-budget mindset to even think that way any more.

Intel has no motivation whatsoever to produce anything ground breaking. They can make minor technology adjustments for years for the foreseeable future.

Yup... as they say, "can't fix stupid." It's the unfortunate reality and symptomatic of a displaced preoccupation with small low-power devices for small low-powered minds.

The six core thuban was actually pretty decent if you knew how to handle it.
6 cores at 4ghz with a raised northbridge clock did pretty well for itself, their next chips were actually a step back from that. -
Anyway, AMD really does need to improve their stuff. As far as I see, they're just boosting clock speeds and rebranding their high end CPUs and GPUs over and over (with the sole exception being the R9 29*x cards). They're making their stuff cheaper each rebrand, but while intel is screwing up with haswell, they DID make clock-for-clock improvements. My 4800MQ destroys i7-2700K CPUs and even people with ivy bridge still have it weaker clock-for-clock than haswell (far less if Mr. Fox had at them with his 4.5GHz daily OC plus his 780Ms which I'm sure he can crank up to make SLI GTX 770s look like a downgrade to a laptop), and when comparing to AMD, the FX8350 needs to hit ~5GHz to match the performance I get at stock in this laptop. It's a joke right now. -

I read this whole post and I didn't want to believe that the conclusion was it didn't work. Sounded like you went through hell and back and still didn't get it going to me it sounded like power issue
-
I think it would have worked if I got two working cards to begin with

Gonna be finding out what this machine can really do... Liquid Ultra, Gelid GC Extreme, and a dual A/C adapter converter box incoming

I'd still be interested if you could hack the clevo box somehow. Maybe resolder the right leads and put in a manual connection from one of the data pins.
-
I would really like to try that, Brother Meaker. If nothing else it would be informative to see what is inside of the converter box. I have been looking for one at a good price and have not seen one yet. I think I could change out the input sockets to the center-pin design and I already have a spare output cable I can use. The data pin is actually not required to use the AC adapter strictly for AC power. It is only needed for battery charging, so for benching having the data pin is totally optional. In fact, if you connect the ID wires to ground wires (on the AC adapter end, not the computer end - the computer end is left disconnected in this example) it seems to force both AC adapters to output full power instead of dynamically adjusting based on load. I've tested that and it seems to work OK other than no battery charging. (I disabled the AC adapter warning in the BIOS.)

Laptop Parts Now has it for 60 bucks if you want one. It's a Clevo original, mine will be here Monday thanks to FedEx screwing up and shipping it to California instead of Colorado otherwise it would have been here today.
Great service from them too. The day I ordered it, they called me to make sure I knew what it was and to make sure I had two compatible power adapters.

Could you provide a link? Googling laptop parts isn't very... productive lol

Well, $60 for an experiment is not very cheap. But, curiosity carries a price tag I suppose. With shipping it's close to normal price. I was hoping to get one really cheap (like $30 or less).
I went ahead and ordered one so I can check out what is on the inside of it and compare that to my dual AC adapter mod. This sells for quite a bit more than what my homemade convert box cost me to build, so it definitely not a more affordable option. -
Yeah I've spent a good bit on this laptop too... Almost 5k for the machine and now I've bought IC Diamond, MX-4, GC Extreme, Liquid Ultra (which just got here today and my syringe appears intact which is awesome), and the converter box. Lol
Oh and ArtiClean too.

This in dilute form is what I use to clean off Liquid Ultra.
-
That's a bit extreme :O
Sent from my HTC One_M8 using Tapatalk -
Well Xtreme chips deserve extreme treatment amirite?
Jokes aside, I'm a chemist and curiosity got the better of me, but dilute hydrochloric acid really has proven superior to anything else I've tried. -
I was under the impression that it's not *that* difficult to remove.
So do you use the pad that comes with it before applying it?
Sent from my HTC One_M8 using Tapatalk -
I don't use the pad anymore. As far as I can tell it's just alcohol soaked paper towel, nothing special.
I only use acid because I have regular access to it, and I find it to be much faster at least for me. I just dip some Q-tips into some dilute acid, then gently swab them over the die and heatsink until both are clean. The nice thing about acid is I don't have to worry about using too much force, as if I wipe the surface too hard some of the Liquid Ultra seems to be become bonded to the die/heatsink. The other bonus feature is that acid cleans off any degradation products like a champ.
Just got my 880M twins!
