Since CPU upgrade random lag spikes occur and cpu belives itself to be 150-200c

[Spruce_Moose]

I have recently upgraded by CPU and it has been going alright apart from the fact that on high end games like rome 2 and war of the roses every couple of minutes the game lags to like 15fps for 4 or so seconds and then goes back, on more lower games like warband it does not really occur at all. The strange part about it is sometimes when i play a particular high end game for long enough or randomly it will stop doing it on all games, i have check cpuid and speccy and it says that my cpu is 150-200c (which is impossible) and if i alt tab out the game the temp on the screen rapidly goes back down to a normal 40c and if i go back into the game and a lag spike occurs it goes straight back up skipping all other numbers to 200c or less. i really need someones help please

Things i have tried:
CC cleaning PC
Virus/malware checking
Defragging
making sure and positioning heatsink on CPU

Specs:
Windows 7 64 bit
AMD fx 8350
8gb ram 666mhz
MSI 760Gm-P21(FX)
AMD Radeon 7870
298gb seagate hard drive

Sounds like it is overheating, of course those temperatures aren't realistic, but it's probably getting hot if it has a stock cooler. Did you reuse the same thermal paste when you repositioned it?

Your motherboard doesn't support that CPU. It only supports 95w FX. http://us.msi.com/product/mb/760GMP21_FX.html#/?div=CPUSupport

Was thinking of the wrong one, logain is completely right.

My friend has the same MOBO and CPU and it works fine, my mobo has not had any problems or crashes cus of it is just this annoying random occurance in games and i have checked it is fine and it is so i don't understand and on another website (quite a while ago) it said that it was fine and it works fine really i can manage it doing that the main and really only game it does it on is war of the roses and occasionally on some other games

Okay, although logain has pretty much pointed out the core issue, still did you update your BIOS to the one that supports the 8300?

 

[ewok93]

There isn't one, because the hardware does not support it.

ewok, I am talking about the BIOS support for FX8300....cpu support list does not show 8320/8350 but it does have the 8300. I am assuming that upgrading the BIOS to that of the nearest supported chip might help. OP insists that their friend does not have any problem with the same config.

But yeah chances are slim.

 

[ewok93]

The newest BIOS may help with the 83x0, but it does not officially support it.

 

[logainofhades]

125w chip in a 95w board = bad time.

 

[Spruce_Moose]

In the BIOS it registers the FX 8350 and shows all its cores and information etc

 

[Spruce_Moose]

AH i have kind of figured it out, the reason it does it on WOTR on like its full load is cus its trying to go over like 95w of useage meaning it has to slow the game down, but is there any way to power back my CPU so it does not do it?

 

[ewok93]

No. You need a new motherboard. Not really an option.

 

[satyamdubey]

Ewok is right. OP, you would burn/damage your motherboard's VRM's if you keep stressing them with a higher wattage cpu under load.

Usually, the motherboards, which have a higher than supported wattage cpu in them, would downclock the cpu to meet the TDP and required voltage demands but all this will still stress your vrm's as your cpu will constantly instruct it to provide it with a voltage (and consequently power) than what it is designed for.

Save the motherboard and your cpu too by getting a proper mobo. Auction off the existing mobo if you do not need it.
