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?

 

[lambda]

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.

 

[Veseleil]

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.

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

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

 

[Dr. Dro]

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.

 

[Remeca]

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

Have you tried the XTU?

 

[Remeca]

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.

Admin if it's against rule to ask for opinion on already open thread please disregard this message.


so I have a 4790k on MSI b85me45, it's basic oc menu allowed me hit 4.5 at 1.15v , I just want to know if there is anything I can do to bump my ram frequenc, currently I have 1866 2 sticks of 8gb limited to 1600 due to max support of mb to 1600, anyway I cns amend these settings ? I can share bios screenshots if it can help, and one more thing I did delid my 4790k as at this point internal paste was dry as rubber and even at stock it was hitting 100.

After delid on Aida stress test max temps are 80.

In short: No. It would list upto 1600 and then "1866/2133 OC" etc, if you're lucky and have the option best you can do is to tune the timings and reduce CL etc if you even have those options in the bios

If you are serious on getting performance out of an old platform, get a good Z97 Motherboard.....

Example I have a 5775c & 4790K bother running on a Asrock extreme 6 MB. PCIe Gen 3.0 ect ect....paired it with some DDR3 2133 and a 4090 and 5070Ti .....just for fun

I know I need a Z97 but they are very rare to find these days In fully working condition, and if available are insanely expensive. So unless there is a point to prove I don't consider investing this much in it, I would rather go with 12th gen i3 at this moment at price similar to Z97 alone.

I did something similar.

i3 13100 with a 4090 (until at the time my 14900K came in)

If you game at 4K its not a bad choice, at this point in time I'd try for a 13 or 14th gen I3 are they are clocked a decent amount higher vs the 12th gen I3 and those 13th and 14th gen are cheap these days now

People get carried away thinking they need the best CPU possible when in fact the lower end CPU's can do just fine depending on what you use case is

Well, out of nowhere, a potentially reasonable deal for Z97 Gaming 5 appeared. What would you suggest? From reviews, I could gather that it needed a lot of voltage for stable OC. The 4790k is currently at 4.5 at 1.2 stable across all tests, and max temp after changing thermal paste doesn't exceed 75 on torture tests. Should I upgrade it? i have 1866 ram 16 gig that's limited to 1600 due to b85 but having air cooling only can I expect to push 4790k further ? as I tired 4.7 and that took at least 1.3 v that would heat it a lot so basically the only potential benefit currently in sight is ram from 1600 to 1866 .
Further, I added custom heatsinks with thermal glue/silicone as suggested in the forum for VRMS. The airflow direction is from intake to exhaust (linear, both 120MM fans), which keeps the air moving across these VRMS.

The 4790k is currently at 4.5 at 1.2 stable across all tests had to raise the voltage in .01 till it was rock solid, and max temp after changing thermal paste doesn't exceed 75 on torture tests. Should I upgrade it? i have 1866 ram 16 gig that's limited to 1600 due to b85 but having air cooling only can I expect to push 4790k further ? as I tired 4.7 and that took at least 1.3 v that would heat it a lot so basically the only potential benefit currently in sight is ram from 1600 to 1866 .

and I currently don't have 4K and GPU I use is 5700xt so basically its all mediocre build for gaming for half hour on weekends.

 

[Toothless]

You might as well read reviews for OC'd 4790k results compared to stock and judge if dishing out that kind of cash is worth it or not. My old 4790k at 4.6 was still enough to be a bottleneck for a 1080ti which I didn't think was possible til I upgraded to a 3700x.

Doesn't make a whole lot of sense to put money into a not-so-big upgrade when you don't even use it that much anyway.

 

[TheinsanegamerN]

No, you will not be able to overclock. To overclock intel with mobo settings, you MUST have a Z series chipset. No office PC came with a Z series chip.

Now, yo can use Throttlestop and might be able to adjust core settings from within windows, but given the bare minimum VRM and cooling most OEM PCs have I'd just run it at stock settings and call it a day.

taking into consideration the total cost involved of only ~ 10 USD (got good deal for B85 and z97 both way) , I bought it, 4790K is at 4.6 is stable at 1.2 volt MAX temps don't go into 80s and I bumped ram to 2000 (1866 original) for current testing, if it allows going over 2k it would be a cherry on top, basically a crazy deal appeared for MSI z97 gaming 5 costing round 35 USD that made it possible.

Some H series boards actually supported overclocking in the Haswell era. I had a cheapo Gigabyte H81 board which worked perfectly fine with a G3258 @ 4.7GHz 24/7

Though I still wouldn't have ran any quadcore OC'd with that board.

Did you delid the CPU? I'm sure that those 10+ year Haswell original TIMs are dry as hell today.

 

[docnorth]

Your proprietary board should be something like H97, so no overclocking. Elite G1 usually have better quality than cheaper series, including MB, but I don't know what difference a 4790k stock would make. Just keep it as it is now imho.

I always thought the G3258 was given some sort of special exemption myself... for my G3258 I had a Z97M-PLUS, not a very good motherboard but it did the trick. Also tried it on the Sabertooth Z87 I used to run my 4770K with. Eventually I got a 5775C for the Z97, but that was many years later. Probably still the most interesting CPU Intel ever released to consumers
