cpu upgrade

Trying to find out if I can upgrade my all-in one from  an I5-4670 to I7-4790k.

Hi

Your PC's CPU upgrade options are at this link (https://support.hp.com/ca-en/document/c04315045 ). Look in Processor Upgrade Information.

Your choices are not on the list. You can do a 4670T or a 4765T.

So the I&-4790k won't work even though its a lga1150 socket?

@Cracon,

The fact that the motherboard manual of the HP Pavilion 23-g109c All-in-One Desktop PC (https://support.hp.com/us-en/document/c04014873) doesn't list the i7-4790K means little in and of itself.

You see, if I had believed these manuals, for example, I would never have fitted an i7-7700K in an HP EliteDesk 800 G3 SFF (see: Solved: Upgrading HP EliteDesk 800 G3 SFF - HP Support Community - 8251218 + HP EliteDesk 800 G3 SFF Performance Results - UserBenchmark) or a Xeon E3-1280 v6 in an HP Z240 SFF (Solved: Upgrading HP Z240 Desktop Workstation SFF - HP Support Community - 8427878 + HP Z240 SFF Workstation Performance Results - UserBenchmark).

The aforementioned processors work very well indeed in these upgraded legacy desktops, despite the fact that you'll fail to see these CPUs listed in their respective manuals as being compatible.

The more pressing issue is not just the LGA 1150 socket or the Intel chipset compatibility, it is the processor's TDP.

According to "the manual", the max processor's TDP your AIO can be fitted with is supposed to be 45 watt.  I said "supposed", because this limit is either real -BIOS programmed, or it is more something like a "guideline" -to quote Captain Barbosa, because the higher the wattage of an installed CPU, the more HEAT it produces, and USDT's, AIO's and SFF's are mostly ill-equipped to move sufficient air through their PC cases to sufficiently cool high-TDP CPUs.

Btw, when you look at this compatibility Table for the i7-4765T : https://www.cpu-upgrade.com/CPUs/Intel/Core_i7/i7-4765T.html, you'll see that the i7-4790K is not even listed -or the i5-4690K for that matter. These processors have very high TDPs (88 watt), whereas your AIO's manual lists 45 watts as its max TDP.

It is likely that the high TDP makes the i7-4790K & i5-4690K incompatible with your AIO. Same story for the i7-4770K (84 watt TDP):

You'll probably be more successful to fit one of the blue outlined 45-watt TDP processors in this Table if you are looking for a higher performing CPU for your AIO.

Hope this was helpful.

Thanks for the help I was also concerned with the TDP of the 4790k being to high for the heat transfer pipes on the unit. I think I 'll just go with the I5-cpu that I put into the unit last year , Its just a secondary machine. But thyanks it was good to know.

@Cracon,

You are welcome -glad I could be of assistance.
