I have the AMD FX-8350, and I have it 100% stock, regarding performance. The multiplier keeps jumping around, and it's affecting my performance. What do I do? Already disabled all power saving functions from the BIOS. I posted this on AMD's forum as well, didn't get it resolved.

Any help would be appreciated

The MULTIPLIER jumps around or the core clock? What are your temperatures and what motherboard do you have?

Dark Lord of Tech · Mar 15, 2015

What board?

bluebob951 · Mar 15, 2015

Reset bios back to default by clearing it! Start with that, then after its all defaulted turn off all power savings. also you running windows 8?

HDD-Mod · Mar 16, 2015

Okay. I have an ASUS M5A97 Le R2.0, Temperatures are all 100% normal. MB stays at 31-34 Celsius with Prime 95 for hours. I have the Cooler Master Hyper 212 EVO Which keep my CPU at 46 Celsius under 100% Load WHEN It is steady at x20, so 4000 MHz. When it drops to x7, the MHz drops to 1440. I have attached a video of what happens. CPU VCORE Voltage drops from 1.260 to .900 as well.

My PC specifications;
CPU - AMD FX-8350 @ 4.00 GHZ
Cooler - Cooler Master Hyper 212 EVO
GPU - Sapphire Radeon R9 270X 2 GB

Just reset the CMOS, testing now. Left everything default.

HDD-Mod · Mar 16, 2015

Just Ran another Prime95 test, everything default, see above. Ran for 22 minutes, perfectly steady at x20.5, and now it jumping around again. What should I do from here?

Get Asus AI Suite 2 and show us your VCORE temps in the thermal radar: http://dlcdnet.asus.com/pub/ASUS/misc/utils/AISuiteII_XPVistaWin7-8-8-1_M5A97LER2_VER20401.zip

It could very well be your motherboard throttling because of it having no heatsink over the power delivery system.

HDD-Mod · Mar 16, 2015

Could be. The research I've done is saying the motherboard can't deal with the needs of the 8350. http://i.imgur.com/azN35Ya.png

Dark Lord of Tech · Mar 16, 2015

That motherboard can't handle a 125w CPU.

Has a poor power phase and thermal design.

Have you tried disabling turbo boost?

HDD-Mod · Mar 16, 2015

Turbo is Disabled.

bluebob951 · Mar 16, 2015

its not the best but it does support it, go check here.

Can you stress it with something besides prime 95? like Aida 64? Prime always messes with my 8350...

HDD-Mod · Mar 17, 2015

I use this computer for some gaming, Far Cry 3-4, Call of Duty Advanced Warfare, as well as Hitman: Absolution, Sniper Elite III and a few others. The heaviest usage is x264 work, because I encode lots of movies at the highest quality from Blu-Ray. What SR-71 said makes sense about the VRM not having a Heat Sink. With x264 it still jumps around. Call of Duty uses 100% of my CPU, a first for games, but it's a beast game.. I have AMD's R9 Sapphire 270X Dual-X, so my GPU is fairly decent. But I'm at the point now where I may upgrade my motherboard sometime, hopefully soon, depending on the need.

Is there any way I could mount a small fan over the Voltage Regulator? Would that even help?

HDD-Mod · Mar 17, 2015

Just checked the Mosfets on the motherboard with laser. They're running at 80 Celsius, 176 Fahrenheit. Heatsinks maybe? Or just skip it all.

HDD-Mod · Mar 17, 2015

Just ordered heat sinks from newegg. http://www.newegg.com/Product/Product.aspx?Item=N82E16835708011&cm_re=Enzotech_MOS-C1_MOSFET-_-35-708-011-_-Product

Will update this when they arrive and I install them

bluebob951 · Mar 17, 2015

HDD-Mod :

80C is not that hot at all, should still be okay. do you have any over clocking software installed?

HDD-Mod · Mar 17, 2015

Completely STOCK. 4000 MHz

NightAntilli · Mar 17, 2015

Sounds simply like the Cool n Quiet feature... It downclocks the CPU when idle. You can turn it off in the BIOS if you wish.

bluebob951 · Mar 17, 2015

You have the latest bios? also it seems like its throttling, as soon as it gets over 50C is cuts back its clock speed. Thermal throttle is usually enabled by default, try and disable it maybe?

HDD-Mod · Mar 17, 2015

I just ordered 2 new 120 MM Fans for the Front intake and Rear Exhaust, as well as a fan speed controller. When I take the side panel off my case, the MHz on the Processor stays steady. Problem solved. Airflow. Also, the Heat Sinks are on the way, so that should fix the problem permanently!

i have the same problem i bought the fx 8350 newly and when i check CPU-z my voltage is not stable on stock am not over clocking the voltages jumps to 1.45 and goes lower to 0.897 or something close to that, is it normal or not, also the multiplier it changes between 20x and 7x only for few seconds when it hits 7x the CPU speed is 1440 Ghz and the voltage is some where around 0.9xx my build is below:

am using stock heatsink and every thing else is just stock and the MOBO is on auto every thing is auto

system: windows 7 sp1 64-bit
Mobo: asus crosshair v formula z
memory: 8gb corsair vengeance pro 1866Hz
PSU: Cooler master bronze 750W

bluebob951 · May 11, 2015

Thats normal, its amd's cool and quiet feature. Its a power saving feature, although i'm not sure why its going to 1.45 for stock, that seems pretty high for default clocks.

bluebob951 :

thank god then that its normal i was afraid that the CPU was damaged or something, now regarding the 1.45v its like for few seconds i mean it ranges between 0.9xx up to 1.45 and that's for a matter of seconds, cheers m8 you made my day
