Upgrading HP EliteDesk 800 G5 SFF Part II

[Friddle]

Hello,

I have 2 sticks of Corsair Vengence LPX 16GB 2666MHz:

This screenshot shows 1067MHz is the highest clockspeed without XMP, which matches the 2133(4)MHz that Task Manager shows:

So yes it looks like it is caused by the type of RAM I have installed.

Here is my userbenchmark results:

Which low-profile RAM would you recommend to unlock the 2666MHz clockspeed?

And is there anything else I could do to optimise my system and up the userbenchmark score? other than upgrading the CPU cooler.

Many thanks, Friddle

@Friddle,

Yes, it is the doggone Corsair Vengeance (p/n: Corsair CMK32GX4M2A2666C16) RAM's "SPD" (default) speed setting all right:

Link: VENGEANCE® LPX 32GB (2 x 16GB) DDR4 DRAM 2666MHz C16 Memory Kit - Black (corsair.com).

For 16GB RAM modules I would recommend:

Timetec: "Timetec 32GB KIT(2x16GB) DDR4 3200MHz (or 2933MHz or 2666MHz) PC4-25600 CL22 1.2V Non-ECC Unbuffered 2Rx8 Dual Rank 288 Pin" as seen here, for example: Timetec 32GB KIT(2x16GB) DDR4 3200MHz (or 2933MHz or 2666MHz) PC4-25600 CL22 1.2V Non-ECC Unbuffered....  Which I purchased for my HP EliteDesk 800 G5 SFF.

Crucial: "Crucial RAM 32GB Kit (2x16GB) DDR4 3200MHz CL22 (or 2933MHz or 2666MHz) Desktop Memory CT2K16G4DFRA32A", as seen here, for example: Crucial RAM 32GB Kit (2x16GB) DDR4 3200MHz CL22 (or 2933MHz or 2666MHz) Desktop Memory CT2K16G4DFRA3....

Silicon Power: "Silicon Power DDR4 32GB (2x16GB) 3200MHz (PC4-25600) CL22 UDIMM 288-Pin", as seen here: Silicon Power DDR4 32GB (2x16GB) 3200MHz (PC4-25600) CL22 UDIMM 288-Pin Desktop Computer Memory at A....

Hynix: "SK Hynix 32GB 2X16GB HMA82GU6JJR8N-VK DDR4-2666MHz PC4-21300 288-pin", as seen here, for example: SK Hynix 32GB 2X16GB HMA82GU6JJR8N-VK DDR4-2666MHz PC4-21300 288-pin UDIMM ram memory 1.2V - Newegg.....

For 4 x 8GB RAM sticks, I would recommend Samsung (p/n: M378A1K43CB2-CTD) 4x8GB.

@Friddle,

If you don't mind sharing your UserBenchMark performance link, I will take a close look to see what, if anything, you can do to optimize your rig.

@Friddle,

Let's start with improving your i9-9900K performance.

Take a look at this most helpful Windows optimization YouTube link and follow the steps: Ultimate Windows 10 Gaming Performance Optimization Guide + GIVEAWAY [SPON] - YouTube.

If I am not mistaken, this alone will significantly improve performance!

Hello,

A very informative video you provided, thank you.

I will be sure to change what I haven’t already. I’ve already tried to optimise windows by changing a few things like the power settings and performance options.

Is there anything else I can do to increase the performance of my CPU? While in game the CPU clock speed sits at around 4.4-4.6 GHz. Is this normal? The max boost is shown on the box as 4.9-5GHz. I would assume I’m thermally limited, but I am unsure.

many thanks, Friddle

@Friddle,

When you go to the first page of this discussion thread, you'll see that I had a similar question.  In short, yes, your observed 4.4-4.6 GHz processor speed is most likely linked to thermal throttling.

If you don't mind, please download/install/run the freeware Intel's Processor Diagnostic Tool (IPDT), as can be found here: https://www.intel.com/content/www/us/en/download/15951/intel-processor-diagnostic-tool.html.

Also, if you haven't already done so, download/install/run the most useful freeware utility program "Speccy" at the same time you run IPDT: https://www.ccleaner.com/speccy/download/standard.  Choose the "CPU" tab:

What I would like you to do is to watch the 8 Cores temps (see left side of picture) very carefully when you run the IPDT.  In my case, the Cores temps are highest when it runs the "Math" test module: my temps reach 87~88°C. If yours go higher than that, you really need to increase your desktop's air flow, specifically through your CPU heatsink.  The "IPDT's "Measured frequency" should be close to 3.60 GHz. Also, make sure you have enabled virtualization and hyperthreading in BIOS.

@Friddle,

Purchased the 500-watt power supply (p/n: L77487-003) from a Trusted eBay Seller:

Dear Forum,

Last week's bid for an i9-9900KS was not accepted, thus submitted another offer today:

Esteemed Forum:

And there we go: "Order Confirmed":

Definitely the fastest/most expensive processor I have ever purchased so far for any of my HP legacy upgrade desktop projects.

Let's see if we can make this bad boy work on my HP EliteDesk 800 G5 SFF!
