Tech support for CPU assistance
I'm working on a 5-year-old Lenovo prebuilt PC using the Intel Comet Lake B460 WIN DPK. Earlier I mentioned my motherboard was the Lenovo 3717, but that's not correct. The feedback I received matches what I said before. I'm still searching for a suitable CPU and motherboard upgrade under $300, thanks. Edited February 6, 2025 – information mix-up
That is physically impossible. What I suspect is the case is that they made multiple PCs with the motherboard called 3717 and that yours is a different generation, or you found the motherboard model incorrectly. Either way that's not possible. It's not that much higher of a clock speed, so while it is a bit better of a gaming chip, it's not enough to upgrade to, plus eBay prices for these is generally pretty terrible. Realistically, if you want to get an upgrade, you need to get a new motherboard. There isn't really any way around that, as the only chips on that socket that are an upgrade also draw a lot more power, and given Lenovo's history with power delivery are likely to power throttle and not give much of an upgrade anyway. Start with a budget and we'll see what we can do to help get an upgrade specced out, assuming it's possible.
You're asking for clarification on what you mean by that phrase. It suggests focusing on actual performance rather than just comparing clock speeds across different generations. The 10400F uses an LGA 1200 socket, while the 8700K is LGA 1151, so they’re not interchangeable. Comparing base clock speeds isn’t the right approach—overclocking could unlock more power from the 8700K, but it’s unlikely you’d be able to do that on a Lenovo prebuilt system.
You just added hwinfo and your motherboard lists as Lenovo 3717. It mentions an LGA 1151 socket, which means you should focus on compatible CPUs for that setup.
I mean it’s just extremely slow, really so. I checked my motherboard model, which is a Lenovo 3717, and it seems to have an LGA 1151 socket with an LGA 1200 chip—so I’m not sure what’s happening there. I didn’t just compare the base clock speeds; they’re pretty similar except for the higher clock speed, but I think overclocking a Lenovo prebuilt would be tough if not impossible.
I've opened it up around 7 times (out of curiosity and to upgrade the GPU and RAM) and not only could I not find a model number somehow but there isn't a visible CMOS battery either. It's a Lenovo PC my dad got from Costco so it's pretty bad alone and I've had it for nearly 6 years now. Unfortunately I can't afford a new PC atm so I'm just looking for whatever upgrades I can get.
It seems there are two possible directions for that board, or something might not add up. It’s impossible for an LGA 1151 socket to fit an i5 10400 without modification. It would be better to specify the exact prebuilt model you have, which will provide clearer details about the system. Could you share a budget range for the upgrade? As I mentioned earlier, I’d treat the motherboard as a loss since any CPU would only offer minimal improvement, so it makes more sense to upgrade both together.
The exact model is the Legion T5 28IMB05. A sensible upgrade budget... hard to judge. I don’t usually purchase parts myself since I can’t afford everything, so I generally get upgrades for birthdays or Christmas—like 4 sticks of 8GB Corsair Vengeance DDR4 3200MHz and an AMD RX 6600. So a budget under $250 seems reasonable? My dad got the GPU from Newegg with help from his cousin (a computer expert), so it probably didn’t exceed that amount. I’m aware there are CPU/motherboard bundles around $300, but I usually think buying separately would be more cost-effective (not sure why). As for the board versions, I see mixed results online, meaning different models might exist. I’d consider replacing the motherboard, but I’m unsure if I can handle it without risking damage to components.
the socket details aren't visible in the hwinfo, only the chipset info is listed. this might mean the research you're doing won't align with the available data.
