Hello, I have been trying 2 small ff PCs, one HP Z2 mini G9 (i7-13700) and one Lenovo P360 ultra (i7-12700). I decided I will keep the Lenovo, but though I might as well keep the more recent CPU.
After the swap, the HP booted fine, but the Lenovo didn’t, the fans spin for a second then off. It never gets anything on display.
I though I had screwed up while doing the swap or reassembly, so I took off the CPU again, checked there was no damage, put it back with fresh paste again, still no luck.
I am aware that both CPUs manage different Max ram speed (4800 vs 5600) so I tried to swap, or leave just one module, no luck.
I though I fried the CPU somehow, so swapped back to each their own, and all works.
Both sockets are LGA 1700/1800 as far as I can tell. Both power supplies are identical, both CPUs are the 65w tdp versions (ie not the T or K versions). The only difference I can see is that the 12th gen is vPro, 13th isn’t. Both BIOS were updated prior to the swap.
Am I missing something? Thanks for any advice.
PS. Both machines came with an nvidia t1000, and I tried with or without in case it was a power draw issue, it doesn’t seem so.
I think from this forum post Lenovo are dicks and don’t support upgrades to a newer generation CPU. Which checks out it is Lenovo after all.
Well damn… The hardware is really identical between the p360 and p3, so it must just be a line of code in the BIOS… Well no luck, I’ll stick with the 12th gen. Thanks for the link to the forum
The Lenovo BIOS may not support 13th gen.
Stupid question perhaps, but are you positive both systems use DDR5? The 12th gen also supports DDR4 motherboards. DDR5 CPUs will also work youth DDR4, but the other way around is a non-starter.
Then there’s the issue of chipsets. I think the cheaper ones won’t support just any CPU with the correct socket. Maybe the Lenovo unit has a cheaper chipset. The vPro thing could definitely be a factor here.
Both 12th and 13th Gen. CPUs support DDR4 and DDR5.
Bios upgrade?
