CPU clock is lower than expected when doing benchmark

[moneymaker0886]

hi everyone

 

I just purchased a used cpu i7-4790k to fit my old motherboard socket

First while gaming, I notice an upgrade and better performance, but I would expect more from it.

I went to run a benchmark and notice my CPU is performing way below average.

 

I do have turbo clock ON the bios and my power saving mode was set to performance. 

My cpu use constantly 4.54ghz on idle almost nothing in background. I've been told that it's normal behavior to be at max turbo on idle, but I do not understand why it goes above the manufacture recommandation. It is rated to be 4ghz and turbo 4.4 ghz

 

Whatever, the reason why I am here is because I ran a Benchmark test to check the CPU performance. It will only reach 3.35 turbo. Tt should go to 4.4 or at least 4 ghz.

Only the very first bench after my gaming session was 4.15Ghz. You can see in history. 

I start suspecting power supply not good enough for my pc. 

If you check the link I run a 1080ti combine with i7-4790k on a B85m-g R2.0 motherboard micro atx.

 Also 2 hdd and 1 hdd with multiple gadget plug in the pc.

This is all supported by my 550w master elite v2

With aorus engine Gigabite tool, I tried to lower the GPU power target to 90% and 75% but barely notice an upgrade of the CPU at 90% and nothing at 75% cpu.

 

I am wondering if on high load while gaming if I get enough voltage for all of this. Why and how can I push this CPU to have better performance under load?

Notice that even my gpu doing average. How can I test my voltage under high load or something like that?

 

CPU temps is normal and I install myself. 45C on iddle and 68 while gaming.

 

I also think it could all be related to BIOS SETTINGS. 

 

I hope this post is nice and clear. Thanks for reading.

Checked the temperatures? Which CPU cooler?

 

Using the Intel Chipset drivers? Using CPUBalance? Latest motherboard bios?

[Somerandomtechyboi]

What board are you using? Ideally youd clock that cpu to 4.8+ as haswell are pretty good overclockers

 

If you are just gonna leave it stock or have a garbage board that cant overclock the  dont even bother with a k cpu

Checked the temperatures? I double checked while gaming and doing multifonction to max out the cpu and notice a little overheat. 74-75 Celcius. I will get that check. Which CPU cooler? Intel cpu cooler LGA1150 E97378-001 

 

Using the Intel Chipset drivers? NO Using CPUBalance? NO Latest motherboard bios? Its the very last firmware. Everything set the automatic and boost mode enabled.

Using B85M-G R2.0 before trying to overclock at 4.8 I want to get it at 4.4 while gaming. Right now I get 3.5 while gaming, but full 4.5ghz on idle. CPU at 74 degree celcius, intel state that it should be at 72 maximum. Can temperature cause that lower ghz?

 

I suspect maybe my 550watt power supply is not enough. While gaming the GTX 1080ti possibly sucking all the energy I have. Leaving my CPU with not enough for full Ghz. Does that make sense????

 

I dont want to go and buy a new power supply and do all the installation if it ain't going to do much. I applied thermal paste myself maybe I put a little to much thermal paste.The fan is sitting on cpu very well. But the thermal paste itself is kinda cheap I am not sure. I received a single use thermal paste with the shipment. It's doesn't say much about the type of thermal paste.

 

AND YES I DO CLEANED THE FAN FROM DUST

Usually you need a Z series motherboard to overclock K series CPUs. 

 

Run ThrottleStop and post some screenshots. Main window,  FIVR and TPL windows.

 

Open the Limit Reasons window and post a picture when your CPU is throttling to 3.5 GHz. Turn on the Log File option so you have a record of your CPU performance while gaming. Attach a log file and some pics to your next post.

 

Your Intel CPU will not start to thermal throttle until it reaches a peak core temperature of 100C. The lower TCase temperature spec you mentioned is not relevant

First, replace this piece of junk before it catches fire. With 384w @12v it never can be a 550w PSU.

B85m-g R2.0

Very poor VRM for a 4790K. Probably the VRM is overheating. What cooler is on top of the CPU?

You think VRM overheathing? Maybe you right. how can I check that. 

speedfan say my cpu is at 70 to 75c while gaming but other app such as HWmonitor is more like 99c wobbling quick to 85 an 100.

Unfortunately I will have to stick with my motherboard & Calm down psu wont catch fire.

 EDP CURRENT also went red at some point but didn't catch it on the screenshot.

 

I notice SPEED FAN state my cpu at 70 while ThrottleStop say it's at 99. Also HWMONITOR say 99c

I don't know what to think. I played several hours, is that bad?

SPEED FAN

Do not use Speed Fan. What it is reporting for temperatures is wrong.

 

Your peak core temperature is hitting 100C and that is causing thermal throttling. This slows your CPU down. You need a better heatsink for maximum performance or you need to clean and replace the thermal paste.

 

Run a longer log file. One minute of data is not very much. Play for15 minutes if possible. Exit ThrottleStop when done testing so it can finalize your log file.

I can'T beleive that the 100 is accurate Since it drop way too fast. at the end of the log you can see I pressed windows key to back up and I exit warzone and it dropped quick.

What about the VRM. It reaches the max is that causing any problem?

I will change the thermal and see if its better. But in bios it's around 75 too. So idk

I can't believe that the 100 is accurate

The ThrottleStop log file shows why your CPU is throttling and not reaching its full rated speed. It says TEMP in the far right column of the log file and the peak core temperature is constantly 99°C to 100°C. The peak core temperatures can change instantaneously. It is normal to see an increase or decrease of 30°C or 40°C in one second, especially if you are using the Intel OEM heatsink.    

 

Your previous screenshot shows THERMAL glowing red in Limit Reasons and PROCHOT 100°C is also glowing red on the main screen. This information is coming from multiple sensors and all this information is telling you the same thing. The CPU not running at full speed while this is happening also confirms the throttling problem. It does not matter if you believe this information or not.

 

Speed Fan and the BIOS likely report temperature information from a sensor in the CPU socket. Socket temperature is often times 30°C less than the peak core temperature. Intel CPUs thermal throttle based on the peak core temperature which ThrottleStop, HWMonitor, HWiNFO, Core Temp, etc. all report correctly. There are multiple core temperature sensors. They are not all wrong.

What about the VRM.

Your voltage regulators are not yet a problem. They might become a problem later. ThrottleStop Limit Reasons will report VR THERMAL or VR CURRENT when the voltage regulators are a problem.

 

First you have to fix the CPU thermal throttling problem. Is the heatsink properly attached? Is it tight to the CPU? Did you check to make sure all four push pins that Intel uses went all the way into the motherboard? This is a common problem when the heatsink is not installed correctly. It is best to push two pins into the motherboard at a time. You push them in two at time diagonally. If you push them in one at a time, sometimes the last one you try to push in will not fully seat.

 

Even if the Intel heatsink is properly installed, it is still a low end piece of crap and should be replaced. The Intel cooler cannot properly cool an 88W 4790K. Any after market cooler will significantly outperform the Intel OEM cooler so you can run your CPU at its full rated speed without constant thermal throttling.

Yea if thermal is glowing red then that means the cpu is cooking itself and trying to save itself by throttling at 100c

 

What cooler are you running? If you even want to have an attempt at 4.8 you need atleast a decent 4 heatpipe tower like se 224 xt, h212 (if not overpriced), or prefferably an even beefier single tower/dual tower cooler. Not to mention you cant properly oc with a b board, i think there is a way by downgrading some microcode but its still a b board and the settings are gonna limit you not to mention the vrms cooking themselves

 

First of all upgrade your cooler to something better then delid the cpu with a cheap chinese tool and swap the crummy thermal paste with liquid metal which should help temps alot. Then sell off that junk b85 for a z87/97 mobo

I use speedfan and it seems to match with realtemp/throttlestop readings, good to know that speedfan can be inconsistent depending on hardware

Yo right, my intel fan was not properly installe as 1 pin slightly out. Meanwhile, this did not fix the max out temp on the cpu, it only made it a bit longer before it reach that 100. 

I will get a new heatsink. I just can't decide which one is better for the price. 

 

Thanks alot. It's definitely overeating and "speedfan" made me think I was around 70 to 75. I've placed an external fan facing my Pc and significantly better outcome even after hours of gaming.

 

See you in the Warzone.

Upgrade your cooling. And use the appropriate drivers.

I set up a external fan to cool my PC by the time I receive the heatsinks. The problem now is I have this edp current that seem to slow me down lock at 4.2 gHz while gaming. Anything above 1.1761 V will trigger the EDP current warning. Also notice at a moment that PL1 and PL2 light was engage after starting up PC. After clearing out PL1 & PL2 it wont come back right away. I assume PL1 ans PL2 is Power limit reach. 

 

I wonder if by keeping the same motherboard it's possible to bypass the EDP current which honestly I don't understand what it is. Beside the fact that I've reach the VRM limit I don't really understand at all.

I now get greater performance. But remain limited to 4.2 gHz at 1.17 V. 1.17 volt seem to be the max for the VRM. looking for a way to at least get 4.4 Ghz while gaming.

[unclewebb]

@moneymaker0886 Your motherboard chipset does not support overclocking. 4.4 GHz is only possible when running single threaded tasks. Most games will max out at 4.2 GHz.

 

Try increasing the Current Limit in the TPL window for EDP throttling issues.

You will only get 4.4GHz when just one core is in use. With modern games, that will never be the case, so you're only going to see 4.2GHz, but that's not much of a concern. We're talking about less than a 5% clockspeed reduction, which is pretty much imperceptible in real world usage.

 

If you want to get the full performance properly, you'll need to upgrade your cooler. The Intel stock cooler can't handle an i7.
