CPU lowering base clock

[azm]

Hi guys, new to the forum and looking for some help overclocking my i5 4690k. When I increase the multiplier the base clock goes down, all values are fine in BIOS but not in CPU-Z and aida64.

As you can see in the picture the base clock went down to 95.18 when I increased the multiplier to x44 (don't mind the voltage, still messing around). Any clues?

 

Rig:

Mobo: Gigabyte Z97X-Gaming 3

RAM: HyperX Fury 8GB 1866 MHz

PSU: Cooler Master G650M

CPU: i5 4690k

Cooler: Cooler Master V8 GTS

GPU: Zotac GTX 970

SSD: Samsung 840 EVO 120GB

HDD: WD Blue 1TB

Case: NZXT H440W

That's not your base clock. That's your bus speed.

What's the issue really? Except a number? (Which doesn't matter tbh)...

Your Core speed is 4.10Ghz, what is wrong?

[azm]

Well, the issue is that both Aida64 and CPU-Z gives me a core speed of 4.2 GHz when it should be up to 4.4GHz, and is according to BIOS but not in windows.

Reset your BIOS by removing the CMOS battery for a few seconds with power removed. See if that works. Also, what is your bus speed when your CPU is at stock speeds?

[azm]

Alright I'll give it a shot. When I'm running at stock multiplier the bus speed is at roughly 99.8 MHz.

Look at this:

Though I know in some BIOS'es, The core speed isn't really showing correctly on Windows, but it doesn't really matter.. Meh, atleast 1 or 2 Megahertz more wouldn't make a difference.

Cleared the CMOS, still getting low bus speed. And I don't think haswell is using the old north/south bridge architecture

I wouldn't worry about it that much. You'll just need to apply a higher multiplier to hit the intended frequency.

Thing is, can't go above 4.1 GHz apparently. Getting BSOD @ 4.2 GHz (multiplier set to 44) with voltage at 1.225. Hit 91 degrees celsius with that voltage.

The CPU needs more voltage. And an aftermarket cooler. 91ºC is way too hot.

If it's running at 91c, adding voltage is going to make it worse.

[azm]

Yea i figured I can't up the voltage above 1.225, but 4.1 GHz seems way too low. The 4.4 GHz that BIOS says seems fine, but I don't get why I get different numbers in Windows.

Did you actually read what I wrote?

Nah, not really. Well, maybe for newer chips, mine has been running like that for the last year (ever since I got GTX 780), this guy just doesn't feel like melting down.

Huh. With that temperature I (wrongly) supposed he didn't have one. He shouldn't be reaching that temperature with it, though.
