fwiw- here are some power draw numbers ive been noting during this week of testing ill be doing. (full specs i posted higher up in this thread, but is a AMD 7262 cpu + sm MB- H11SSL-NC Rev. v2.0 -- in all of these test i only have 128gb of ram (4x ecc 3200mhz sticks) + the p4800 nvme drive attached)
- oh, and the PSU here is a consumer (and old) 650w psu. power watts measured with a eaton ePDU rackpower strip

As reference...
I used a 7282 with an Asrock EPYCD8-2T.
I had ~8W off with only IPMI working, and ~75/80W idling (linux) with one RTX 2060 Super GPU, a samsung 970 pro, and four 32gb sticks. ~150W full load (Linux 'stress').
With four RTX 2060 Super cards installed, idle power draw went to ~110/115W.
Using an EVGA 1000T2 Titanium power supply.


Over 14W for just the IPMI server is a bit high...

Is it possible to turn off the IPMI to reduce overall power draw?
I haven't tried or explored this item, but check the manual, I think there might be a jumper that disables IPMI. However, I'm not sure if such a jumper would also completely power-off the IPMI chipset with regards to saving a bit of power.

How? The price I see is double that at HPE.

I can't find this CPU anywhere, nobody apparently has it for even close to MSRP.
A number of us purchased from Provantage back in October 2019 - January 2020 timeframe and it was that price for months. I'm guessing with the parts shortages and demand for server chips CPU prices have gone up substantially. Milan is likely right around the corner if you're considering a new build.

When those posts were made, the price had been $640 shortly before - and as news of HP selling the CPU for below retail spread - it crept up steadily to $660, which is when I ordered mine at the end of April for $678. I had to wait just over a month to get the CPU.

There's a lot of seasonality with enterprise stock levels. If quite a few folk have decided to jump on the AMD bandwagon and are upgrading, you will see shortages in the channel. The HPE part was after all, a HP special and there's no guarantee that HP might decide to continue with it. You're better off watching all the usual suspects (TigerDirect, CDW, Provantage, ShopBLT etc) and checking to see which 7302P part is retailing for the cheapest. Someone I know got the 7302 (not the P) for $750 and that is probably a good deal in today's terms. Be prepared to wait one or two months - you just have to be patient and check stock levels and prices diligently.

..or buy the 7282. It's only marginally slower than the 7302p and runs cooler.

Hey all, sorry to bring up this old thread but came across it in a google search. I am curious what power usage under load I should be using. I just put together a new server using a 7302p cpu and H11SSL-NT board with 256GB ram. Under full load (tested with R20 and prime95) the CPU is only using 135 watts max with all cores boosting to 3.2 or 3.3 I think it was and 55C max temp. Is this normal? I thought this CPU would consume 200 or more watts under full load. I just want to be sure I don't have something configured wrong and not getting max performance from the cpu. I could not find any power settings in bios to change.

Thanks!

You should be seeing more power consumption than that. 155-180w minimum if CPU is maxed. Keep looking around in bios and power settings in OS, there should be a couple of performance related settings.

Thanks, I will look again but I looked in the BIOS a number of times unless it is labeled as something I am not familiar with. Hmmm. R20 score was something like ~7500 if that seems approximately right. Maybe HWMonitor or HWINFO is not reading the power consumption properly either? Ohh it is reading idle of around 45 watts also.

I misspoke, I went back and looked at my findings from 2 years ago and I was seeing about ~134w with the 7302p maxed on Prime95 and a couple other programs. I think you’re right there if seeing similar numbers. I recall the 155/180 numbers AMD uses for these CPU’s as maybe being a thermal or heat dissipation measurement.

Ahh okay, excellent, thank you!

https://www.servethehome.com/amd-epyc-7302p-review-a-category-killer/ - 200W for the full server, subtract 10W for RAM, 20W for the LAN and another 30W for fans, IPMI and storage - 140W for the processor sounds about right. You can also play with Power Determinism and cTDP/ Package Power Limit to allow the CPU to consume more power

Purchased a few things (and even returned one) to Tugm. Even though everything is from over seas, both purchase/return and communication has always been top notch with them.
