fx4100 throttling back

djshauny1 · 17 Jan 2013 at 22:19

Hi everyone

Just built the system and all was well until i tried to overclock it lol

First i thought id just stress test the cpu before hand with prime95 to see if all was well

The cpu keeps throttling back to 3.3ish ghz and wont even hit the 3.8 turbo

Ive disabled all the usual stuff and the thermal control but my problem is still there

Ive updated to the latest BIOS aswell and its exactly the same as before

Been googling around for a bit but i cant find any fix

Anyone have any ideas that i could try?

Thank you

EDIT

Sometimes it even throttles back to as low as 2.5ghz

What do your temps look like during prime?

djshauny1 · 17 Jan 2013 at 22:29

45 max

EDIT

Sorry i was looking at the wrong bit

they are 50 max mate

AMD temperature measuring is bonkers... usually if its 50 that means its around 80 in real life...

Since when?

Prove your point

because cpu temperature can not be below room temperature.

Any help lads lol

They've been this way for ages.
It's not rare to see them report sub ambient temperatures.
At their TDP, the temperatures also aren't that realistic, so, while you may think "My AMD only gets to 62c, whereas the Intel will get to 80c" that 62c isn't really 62c, unless of course a CPU with more heat to get rid of, under the same cooler, can run cooler than the lower TDP CPU

Throw a 12cm fan near the VRM's?

Ill sell the crap i swear lol

Martini1991 · 18 Jan 2013 at 00:14

Ha, give it a try, see if it resolves things.

CAT-THE-FIFTH · 18 Jan 2013 at 00:15

What motherboard do you have BTW??

djshauny1 · 18 Jan 2013 at 00:31

only a cheap one mate

The Gigagbyte 78LMT-USB3

CAT-THE-FIFTH · 18 Jan 2013 at 01:12

That has a heatsink on the VRM too. A number of the Gigabyte 900 series motherboards had the same throttling issues which were fixed via a BIOS update IIRC.

Edit!!

However,I would still try a fan to see if more VRM cooling helps.

what psu?

id try reflashing with the same bios aswell,bios settings seem to not save on these newer gigabyte boards(z77 anyways) reflashing the bios and entering oc settings fixes it

idk if thats the case for amd/gigabyte boards

haha

tried that mate

its the same

thinking of contacting gigabyte for a beta bios if the have one

Fix the vcore at about 1.4-1.45V and see if that fixes it. It sounds like the voltage is dropping under load. LLC may help if you can change the settings higher. Do not leave cpu voltage on Auto.

If the Voltage was dropping to much wouldn't it just BSOD?

Are you thinking that the auto voltage setting is control the turbo feature (turning it down to sit at lower voltages)?

Has the OP tried manually setting clock speed and vcore?

Not tried that mate

Time to got into the bios again

Ill report back
