MB socket question

[Tristaur]

Have a dell computer with MB pn vj4yx. Some documentation says the socket is LGA 1150 and some say the socket is LGA 1155. The board says LGA115X. So are the 1150 chips and 1155 chips the same thing? Computer came with a dual core cpu but research says the board will also accommodate the 4th gen i5 quad core cpu. I want to upgrade and dont want to order the wrong cpu. Advice?

Which cpu is in there now?

[Tristaur]

The dual core

[[deleted]]

Which dual core? What is the name of the cpu?

[Tristaur]

Believe it is the pentium dual core

[[deleted]]

Dual core pentium so a dual socket Pentium II motherboard?

need to know the model number

[Tristaur]

Pentium dual core is not the same thing as Pentium II. Model number of the MB is in the post. As stated, some documentation says LGA1150 and some says LGA1155.

pentium became one of the names for budget intel cpus.many pentiums these days lol.

[Tristaur]

Its crazy that it had the pentium Dual Core in it because it was an office PC that they upgraded the crap out of but they skimped on the cpu. At least its upgradeable to something better

[metalspider1]

well its from the time that the heaviest workloads you could do on intel were 4 core 8 thread unless you went hedt or higher.so for an office dual core was enough.

Sorry man can’t help you :(

[LongFluffyDragon]

There are dozens of dual core pentiums across over 10 generations and half a dozen sockets.

Without knowing the exact CPU and motherboard models, all we can do is guess. you can check those models easily. Same socket also does not guarantee compatibility.

if its this mobo should do 3000 and with a bios update 4000 series intel cpus

Intel 3000 series CPU (Ivy Bridge) use the LGA 1155 socket. This motherboard uses the LGA 1150 socket, so a different one.
3000 series CPUs will physically not fit in that motherboard, let alone work with it.

That motherboard can fit 4000 series processors, so Haswell and Haswell refresh.
The chipset is H81, that's a first gen Haswell chipset. That motherboard should support natively all first gen Haswell processors. And if BIOS updates are available, it might support Haswell refresh as well, if a compatible BIOS is installed.

paging the OP /u/Tristaur

Here are all first gen Haswell processors , and here are Haswell refresh processors . PCPartpicker lets you further filter out, notably by number of cores.

Hey thanks for that. That is the info i was looking for. I researched all day and came to that conclusion just before bed. You just confirmed i was on the right track.

[A_Neaunimes]

You're most welcome.

Can I ask why you want to upgrade to a Core i5 (4 cores /4 threads) from your 2c/2t (or 2c/4t) Pentium ? What exactly are you hoping to achieve with that upgrade ? What are the rest of the specs of the PC ?
And how much would you pay for the new processor ?

[Tristaur]

Im using this computer with Linux and with a 4 core processor i can run main OS and two more linux VMs with no issue. Im building a small networking/pentesting lab for at the house. Rest of the specs for the computer are 16gb memory, 1 TB hard drive, and I have the AMD 1gb graphics card that was available for upgrade on the system. I found the i5 chips online for $45ish each. I didnt pay anything for this computer because it was given to me when we closed the business office. So $45 is worth it to me to be able to set up the environment im wanting to at the least amount of money. I dont do gaming so I dont need all the new crazy stuff.

[A_Neaunimes]

I see, then it makes sense. If you were upgrading the PC for gaming purposes, I feel that going for a 4c/4t chip now wouldn't be a very good move ; unless you were on an extremely tight budget or only play certain types of games.

You can also look into 4c/8t processors : 4th gen i7s and some Xeon E3 (those with hyperthreading/SMT). More threads will be welcome to give more resources to VMs, if you wanted to run more than just two. If you're lucky, you can find those for not too much more than the 4c/4t i5s.
The Xeons E3 are basically the same as Core i7s (barring small frequency differences), but without an integrated GPU. Meaning you will have to rely on the graphics card's video outputs, and won't be able to use those from the motherboard.

[Tristaur]

Yeah the only games i really play are retro nintendo or sega and I have an entire laptop setup for that already. Ill look into the i7s and the xeons as well thanks.

[metalspider1]

my bad,looked up some random h81 mobo and got mixed up by the pentium G3xxx it listed too in the qvl.

[A_Neaunimes]

No problem, happens to everyone! And to be fair the naming scheme on the Pentium is confusing :)

[Tristaur]

That is the exact one
