Precision 7530 & Precision 7730 owner's thread

@Ionising_Radiation So the 8950HK can be adjusted and overclocked (barring the thermal limitations) beyond 90short/60long? And only that CPU? Have anyone confirmed this?

 

I'm actually not sure specific to this model, but based on reports of 8950HKs besides in the Precision, they can be overclocked, and power limits unlocked...

 

Thing is though, on some of those other systems, the power limits on the 8750H and 8850H can be increased as well, and the 8850H can utilize its partially unlocked multiplier to OC +400MHz. So moral of the story I guess, is don't underestimate to what lengths Dell is willing to go to lock this system down, as we've already seen.

 

Ah, you were saying that it was adjustable based on the assumption of other systems.



Someone who linked the 7730 review from 51nb (not sure if it was himself who owns the 7730) that the power limit is locked 90/60 on the laptop.

I had a similar problem with the i9 Alienware 17 R5 where if "performance mode" is not selected on the BIOS configuration, it would not allow the CPU to to beyond 55/45 but gives the illusion of the TDP being adjustable by unlocking PL1 and PL2 adjustment, however, any attempt to change the TDP will be reset by the EC or another part of the bios that monitors the PL1/PL2. The current limits are however adjustable (but useless since the TDP is hardlocked).

The redeeming factor on the Alienware is that you can set the power limit to a locked value of 110/110 using "performance mode" but that doesn't apply on the precisions do they?



If someone has the i9 HK CPU 7530 please shed some light into if the CPU power limits and multipliers are actually unlocked (or not).

 

I have an i9 in my 7730. XTU let's me apply both power limits all the way to unlimited.

Other than bragging rights over short-term benchmark results, I'm not sure why you'd want to do that though. To me, consistent performance over extended time is far more important. I'd rather have a lower short-term performance if that means I can maintain my long term performance. A simply 100mV undervolt allows my i9 to perform at 100% load at stock clocks for half an hour (or more, haven't tested it further). If you let it go all out in it's short term boost, the heatsink will quickly saturate. A marginal computing increase for 30 seconds can cripple performance for the 5 minutes right after.

 

I wouldn't do the shunt mod if you can't afford to replace the 3k laptop on your own. Dell shouldn't have to cover you if you mess something up, and knowingly RMAing something you messed up is unethical in my opinion. While I'm all for modifying things and doing things to pioneer better overclocks, it should be on you if something messes up. Gotta pay to play so to speak.

 

Does the power limit adjustment hold though? Lets say if you adjust it to 75w and only mildly overclock it, does it hold at 75w (given good temperatures) or does it get reset by the BIOS/EC?

Different school of thought ^_^

Pay to play with the warranty

 

So long as you admit what you did and they cover it then I see no issue with that. If you have to lie about it then I say it's unethical. Maybe buy the accidental damage warranty.

 

Hi everyone - new member, first post!

I’ve owned an HP ZBook 15 G4 for over a year now and I’m not very happy with it. It’s had a few really annoying problems and hardware failures. It was a very expensive laptop and though I have a full warranty with next day onsite business support as you all know it’s such a headache to have to deal with phone calls, troubleshooting, and replacements when I need it everyday for work. There are still problems with it that HP hasn’t fixed, and it astounds me that a $3500 - $4000 laptop comes with such low quality.

I ordered a Dell 7530. I really hope it will be a more reliable and stable laptop.

Would someone with a 7530 and UHD panel be able to post the panel name and model number from HWINFO? I want to check the full specs on panellook.com and other resources.

 

Which panel are you looking for? I've got the 1080p anti-glare, non-touch option, and the panel is:
