tech support CPU help

[Its_MTG]

to start, unfortunately I am working with a 5 year old Lenovo prebuilt PC with the Lenovo BDPLANAR Intel Comet Lake B460 WIN DPK. I recently mentioned that my mobo was the Lenovo 3717 (according to hwinfo) which was incorrect and the replies reflect with what I said previously. I'm still looking for a good CPU and mobo upgrade for (preferably) less than $300, any help is appreciated.

my CPU (Intel core i5 10400f) is no longer doing what I need it to do. I searched online and discovered my mobo for whatever reason uses the LGA 1151 socket,

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.

discovered that the i7 8700K has a much better base clock speed and is "exceptional for gaming" but I want to make sure I know what I'm getting, is this worth it?

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.

What exactly do you mean by "no longer doing it what you need it to do"?

 

If you currently have a 10400F, you do not have an LGA 1151 board. The 10400F is LGA 1200. 

 

The 8700k is not even really a superior chip to the 10400F. You can't just compare base clock speed across generations. The true potential of the 8700K would only really come out with overclocking, which I guarantee you you would not be able to do on a Lenovo prebuilt.

I just installed hwinfo and my motherboard model says "Lenovo 3717", and from what I've seen online it uses the LGA 1151 socket so I've been looking for a good CPU upgrade.

by "no longer doing what I need it to do" I mean it's just plain slow, incredibly slow at that. I looked up my motherboard model which is a Lenovo 3717 and it's somehow an LGA 1151 socket with an LGA 1200 chip so I have no idea what's going on there.

 

I did do more than comparing the base clock speeds between the two chips and they look more or less the same besides of course the higher clock speed but I believe you that overclocking on a Lenovo prebuilt would be very difficult if not impossible.

If you want to upgrade you gotta open it. You shouldve just open it and see if there's any model number there.

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.

So again, there's either going to be two versions of that board, or it's just wrong. It cannot physically be an LGA 1151 socket and have an i5 10400 in it. 

 

It would be more helpful to list the specific model of prebuilt you have, as that will give more info as to what's in the system and be more reliable.

Can you give a number for how much you are able to spend on an upgrade? As I said above, I'd consider the motherboard a loss as any CPU you can put into it would only barely be an upgrade, so realistically you should just upgrade the motherboard and CPU together.

the specific model is the Legion T5 28IMB05. A reasonable upgrade budget... idk that's hard to say. I don't really buy parts on my own as I can't exactly afford all that so I typically ask for upgrades for my birthday or christmas i.e 4 sticks of 8 gig corsair vengeance DDR4 3200 Mhz, AMD RX 6600 so I suppose a reasonable budget would be <$250? My dad got the GPU off Newegg with help from his cousin (who is a master with computers) so it couldn't have been more than $250.

 

I know there are CPU/mobo combos that are around $300 but I typically figure buying the parts individually would be cheaper (idk why, I typically think bundles bring the price up).

 

and in regards to the two versions of the board comment, I do see varying results online so it's possible that there are different models of that motherboard. I would do a motherboard replacement but I can't say I trust myself to not damage the components in some way if I did a full mobo replacement.

regarding the socket, the chipset (if that really matters here) is the intel B460 comet lake PCH-V but I'm not seeing the motherboard socket on hwinfo, just the model so all the research I'm doing could just be a wild goose chase.

from a quick check on the Lenovo website, the specific name of the mobo is the Lenovo BDPLANAR Intel Comet Lake B460 WIN DPK if that's of any help, you were right the model name got mixed up my apologies

It's usually the opposite, combos generally bring the price down a bit, especially on used stuff. You can get stuff like this for a pretty good price

There are probably better options as well, this is just what I found within 2 minutes of searching eBay.

OK, this confirms that something is wrong with the readout. Every instance I found that referred to the 3717 as an LGA 1151 board also referred to it as an H270 board, so either HWInfo is reading the model wrong, or there's two versions of the 3717 and you have a different one.

alright, thank you for the help

I would personally prefer to not switch from an intel to AMD CPU (despite preferring AMD CPUs) so I don't need to go through a whole driver debacle but I can try to work with it.

Having done this switch a few times, issues are pretty rare. They can happen, sure, but modern Windows is actually pretty good at dealing with the driver differences so it's not something you need to worry about too much.

alright, it looks like CPU drivers aren't usually needed for a new CPU (quick google search) but regardless I'd like to know if I'd need to do any driver work.
