Regarding i7-4790k and overclocking!

[GordonFreemanInTheFlesh]

I recently picked up an office PC HP elitedesk G1 Tower
Current Specs:
-i7-4770 non K
-16gb samsung 1600
-Motherboard (HP EliteDesk G1 Tower 737727-60)
-GPU- RX580 Saphire Nitro+ 8gb
-500 NVME samsung
-1TB WD Blue 7200
-Power supply 550w standard(with proprietary 24pin to 2x6pin adapter)

My question is will this motherboard allow me to overclock an i7 4790k?
Or will it even run it at stock speeds?

The default motherboards in such devices usually have the bare minimum VRM config.

It'll depend on the power limits configured on the motherboard and the CPU. Quick search tells me that for the 4790k it's 125w short term.

The K series of CPUs usually have higher power limits compared to locked variants.

Don't try your luck honestly.

Tried finding the manual for that tower of yours, looks like it's this one - https://h10032.www1.hp.com/ctg/Manual/c04331008.pdf

Says 4770, 86w, you should give it a read, maybe I missed something.

Does not list boost TDP (84w / 86w is probably the base TDP).

It likely would be able to do it but given the age not really worth putting any more in to it then you have to for a small maybe 10% boost. Other issue would be more concerning is if the cooler would be enough to keep it cool as they might use same board but not same cooler.

 

[Toothless]

Nope. OEM board and all that ain't gonna let you do anything. Don't mess with it and let it do it's thing.

My question is will this motherboard allow me to overclock an i7 4790k?

Only the CPU ratio at best, but no adjustments to voltages or anything RAM related.

Or will it even run it at stock speeds?

Technically it should, with the correct BIOS (it's the Q87 chipset).

Likely not, those HP/Dell etc desktops were predominantly office machines that would run perfectly fine at stock and had a lot of customisation stripped/not available in the BIOS, including but not limited to RAM OC, vcore options over/undervolting, multiplier changing

Only the CPU ratio at best, but no adjustments to voltages or anything RAM related.

View attachment 392478

it will be a HP BIOS, not sure what you mean by the correct BIOS but predominantly there are almost 0 options for any kind of overclocking in HP office machines from that time regardless of the chipset capabilities

Only if chipset is Z87 or Z97, and only if the OEM left the feature enabled in BIOS. EliteDesks were business computers, unlikely to have Z series chipset, so no. i7-4771 or i7-4790 are likely as high as this goes.

 

[Veseleil]

not sure what you mean by the correct BIOS

I mean BIOS version that supports Haswell refresh CPUs (like the 4790k).

And people (did) run 4790k on these boards.
There is a possibility that the CPU ratio is unlocked, as HP don't really make motherboards, but one of those manufacturers mentioned under the OC column did for them.
Another possibility is the XTU (appropriate old version, as the newest one won't work).
But he can't be sure (regarding the OC capabilities) until doing the actual testing.
4790k should work at stock.

Only if chipset is Z87 or Z97, and only if the OEM left the feature enabled in BIOS. EliteDesks were business computers, unlikely to have Z series chipset, so no. i7-4771 or i7-4790 are likely as high as this goes.

It's the Q87.

My Dell Optiplex has a Q87 mobo as well and I couldn't overclock or undervolt my 4790k.

Have you tried the XTU?

Have you tried the XTU?

Yes I also tried with XTU. It couldn't make any changes.

It's an hp they have THE most limited bios ever.
