Precision 7530 & Precision 7730 owner's thread

I'm not sure why you would say that when there's multiple examples in this thread of even the i9 being kept in check.

 

Isn't that on the 7730 with a bigger heatsink?



There's also the PL limitation as mentioned by several people. Can't change the long PL (short too? Not entirely sure on this).

In context, a tuned 4GHz i9 on a liquid metal AW17R5 running its fan on max speed takes around 90w to run ROG Realbench and 82-90w to run OCCT.

 

I can't remember the exact username, but someone here got the similar results on their i9 7530. Also, there's @Ionising_Radiation with his Xeon, which is similar enough.

Basically, all it (usually) takes to get the full performance of the chip is a 100-150mV undervolt, which can happily be applied with XTU to the i9 and both the i7's.

You may be correct about the power limits. It's possible they are only adjustable on the i9. I don't know.

 

Hey.
I have a question regarding Dell warranty.
If I get a 7730 with one ssd, can I put 3 more myself without affecting the warranty of product?
No replacement, just adding.

 

Yes, definitely. The Dell ProSupport warranty is particularly flexible.

 

I think I would get 8850H.
I don't know how to tune the turbo, but I am sure some one will give a clue

Thanks

 

If you undervolt (and possibly also repaste) the chassis can sustain full boost. My 7530 with E-2176M achieves and sustains all cores at full boost @ 4.10 GHz without any issues and temps < 87 C. I undervolted in order to achieve that and I also repasted, unfortunately though I didn't test temps before repasting so cannot give diffs due to it. If I turn the undervolt off even with repaste it thermal throttles and I think can only sustain all core boost @ 3.50 GHz or so.

EDITED: 4.30 -> 4.10 GHz, 3.90 -> 3.50 GHz

 

Isn't this xeon cpu supposed to be at 4.1 GHz max on all cores? (And 4.4 GHz on single core)

 

Sorry I was confusing it another computer I have, yes that's correct. I'll edit the post

 

Well I don't know if this is related to power limit, but my i9-8950k reaches around 4.6 Ghz single core (70°C), and 4.2 GHz all cores (80-85°C). Slightly below rated frequencies, but with undervolt these are sustained.
So from my experience undervolt decreases temps and helps sustaining high frequencies. But rated frequencies are never reached in my case.

Also I noticed this CPU is able to endure strong undervolts while under heavy load (I tested down to -190 mV with all cores stressed: stable). With such undervolts, light load or no load translates into instant system freeze.
