Hi Martin, I'm using HWiNFO64 v4.18-1930 on my Haswell based PC (ASRock Z87 EX 6 board with Nuvoton NCT6776 chip, i5-4670K CPU, Windows 8 Pro 64bit), and it is working fine. I don't see any posts about HWiNFO64 and Haswell PCs in the forum, so just some comments, FYI information, and questions of course.
The Uncore Clock field seems correct, and changes perfectly as the CPU multiplier changes due to SpeedStep and other power saving options.
I really like the Total DRAM Power display! I'm using two 4GB DIMMs, Samsung M379B5273DH0-YK0, at 2133, 1.425V. I'm seeing power values from 1.264W - 1.852W. These values really are the total DRAM power being used by both DIMMs together? I'm not saying it is wrong, just interesting to see it is that low. This memory is low power memory, but not categorized as LPDDR3.
The Z87 PCH chipset is showing temps from ~35C - 40C.
Nice work getting the new basic Haswell CPU voltages correct (which is more than I can say for my board's manufacture...).
The Vccin field (Vcc internal?) seems correct (matches CPU-Z, FWIW) and is the CPU core voltage? (formerly knows as Vcore). I normally see a reading of ~0.900V.
The latest AIDA64 sensors list this: CPU VRM, and CPU Core. CPU VRM seems to correspond to your Vccin (readings match when each program is run by itself, ~0.900V.) The AIDA64 CPU Core reading is ~1.2V. I'm just trying to sort all these readings out, and I realize the CPU voltages have drastically changed with Haswell, and I imagine you and all the other programs are also trying to sort this all out.
The Vccp2 field seems to be the new CPU input voltage, of 1.80V? (default) I'm seeing ~1.856V - 1.864V, which is a bit over the BIOS/UEFI setting (frankly I trust your reading more...) The average value I'm seeing is 0.897V.
BTW, the UEFI and monitoring utility of my ASRock board only displays the CPU input voltage correctly, which they have labeled as Vcore, and has no other CPU voltage displays (OMG...). They are working on this after I pointed this out to them.
I can (supposedly) change the CPU input voltage with a Windows utility, but when I do, I see no change in the HWiNFO64 display. I do see small changes in the Vccin voltage when I change the CPU input voltage.
Any idea if the VIN4 - VIN6 values correspond to anything with Haswell? For example, the Vddq voltage spec seems close to VIN5 (1.680V) although a bit high.
Or, are the VIN4 - VIN6 values VID's for CPU and DDR input voltages?
If I have the new C7 C State enabled, I have seen the Current Core #0 Clock reading become 0.0MHz very briefly, but the Minimum Core #0 Clock value is never 0.0Mhz, just FYI. It does display the new Haswell minimum of 800MHz.
The only new reading I don't understand at all is Memory Channel 0 Rank Max, whose value is 1.0 C, and never changes. What is that and is it even applicable to my platform?
As usual, IMO HWiNFO64 still has the best PC sensor and information displays, thanks for all your work!! It is a fact that you've done better than a major mother board manufacture!
