[Guide] HP Elite 8300 & 6300 Pro (all form factors) using Clover UEFI hotpatch

[LisaAlterEgo]

I checked my memory in two 8300 with i5-3470s and here's some feedback.

In 8300 #1, I have 16 GB installed as four 4 GB DIMMs. One pair is
Crucial CT51264BD160B in black DIMM 0 slots, the other pair is Nanya
NT4GC64B8HG0NF in white DIMM1 slots. The Nanya are PC3-12800U
rated for 1.5V, while the Crucial are PC3L-12800 rated at 1.35V, but
"dual voltage and can operate at 1.35V or 1.5V" according to Amazon.

In 8300 #2, there are Hynix HMT351U6EFR8C-PB 4 GB PC3-12800U
modules rated at 1.5V according to Amazon.

In #2, with one Hynix 4 GB module installed, the Geekbench 4 scores are
Single 3434 Multi 10199 Mem-latency 6243 Mem-BW 1974 Mem-Copy 2634

In #2, with two Hynix 4 GB modules installed, the Geekbench 4 scores are
Single 3669 Multi 11345 Mem-latency 5827 Mem-BW 3245 Mem-Copy 3975

In #1, will all four 4GB modules installed, the Geekbench 4 scores are
Single 3740 Multi 11357 Mem-latency 5723 Mem-BW 3268 Mem-Copy 4272

The bang for the buck seems to come with 4 GB modules installed in pairs,
and the extra benefit of 16 GB seems marginal.

1866Mhz - sets itself to 1777Mhz - 2 x 4GB HyperX White - Single 3667, Multi 11120

The differences don't show up much in the top-level score -- you'll probably find more
relevant data in the memory scores. You're showing improvements of 1% to 2.7%
for RAM which may have a substantial additional cost.

The Nemix RAM below are rated for 1.5V and 1866 Mhz and don't seem to have much of a price premium,
but others like the HyperX seem more expensive:

I have no idea whether they would be reliable in an 8300, and whether the 8300's memory
controller would be able to truly take advantage of their increased capabilities. The 8300 specs
call for CL-11 and some of the higher performance RAMs have different latency.

HyperX only tested for a few hours but seemed ok, wont be testing this long term (the memory came from and will go back into an overclocked (i5 3570K @ 4.4Ghz) Asus based machine.

Interesting, I thought that an HD2500 cpu wouldn't work without a dedicated video card, but my Elite 8300 installed and has completed all updates following your instructions - I'm impressed. There are minor "issues" with video, like a window not closing cleanly, i.e. image breaks up but only very briefly. I don't know if this is the board or a tweak that still needs to be done. I've attached the "About this Mac" dialogue to show how it displays.

I do have a 710 board en route, expecting it to improve the video, although I mostly wanted it to support 2 displays.

BTW I am using the DisplayPort from the motherboard into a 22" ViewSonic display.

Try moving a chess piece in Chess and also see if Quicktime will play a video. HD2500 appears to be partially supported but not officially. Works for some and not for others. @Sniki has been interested in figuring out how to get this to work so if you're interested in helping with this research, let us know. BTW which i5 CPU do you have ?

 

[lapslide2010]

I'll have to check on which i5 cpu it is, long story short, I only bought the 8300 to harvest its i7-3770 for my DH67CL board, and put what I had on that board into the 8300 - got that cpu from a friend.

Chess pieces moved smoothly. As it's a virgin load, I don't have a QT movie to play, but did a screen (moving) capture and then played it back, worked fine. I can download a QT movie off the internet and check that.

I was having some problems with doing the updates, but all those seemed to go away once I took out the USB Installer - forgot it was still in the machine. Booting from it, something seemed to get in the way of the update process's multiple boots. I did update clover to the latest available one and left its default drivers in place, otherwise just copied over the various bits n pieces that were included in the instructions on this thread.

It's interesting to see. Nearly everyone that "unintentionally" gets HD2500 gfx working always seems to have an i5-3550 CPU. Wonder why that is ?

[Guide] Install High Sierra or Mojave on the Dell Optiplex 7010 / 9010 Desktop PC - Revision II

Compiling my DSDT (the one that Clover created) I get errors and warnings about stuff I don't know how to repair. Any idea? If the warnings are not causing any issues they can be generally ignored. The two error lines can be safely deleted and then you will be able to save your edited DSDT.

If anyone else with a 3550 could test to confirm this I'd like to see those results.

Maybe I missed this, but is this guide applicable to a clean High Sierra install as well? I was planning on using the guide by @trs96 but sounds like this guide might be the more stable way to go? Feel free to correct me if I'm wrong or if there's no benefit from using one over the other!
