overclocked CPU goes to 1.6Ghz often for a few seconds mid-game
#1
hi, my i5 2500k is overclocked to 4.3 Ghz but often goes down to 1.6 in every game I've played so far. When this happens the game will slow down, and the frame rate either stays at max or will go down a few fps. I've experienced both, probably because of the speedhacks I've turned on.

Anyway, I know this isn't really a problem with my system because when I play any normal PC game the CPU stays at max during gameplay. Is it possible that I may have inadvertently changed some pcsx2 setting or maybe it isn't high priority in Windows? My CPU doesn't really go above 50% usage in-game (I've checked with MSI On-screen display). It usually stays at 20-30% in-game. Is this normal as well?

Here are my general pcsx2 settings:

GSdx 0 SSE4.1
SPU2-X
cdvdGigaherz
USBnull driver
FWnull driver
DEV9null driver

emulation settings:

everything at default except for MTVU which I have enabled, and EE Cyclerate/VU cycle stealing depending on the game.

my system:

i5 2500k @ 4.3 Ghz
6870 @ 1gb stock clock
8gb ram @ 1333 Mhz dual channel

I'd also like to mention that my CPU's temps don't get high when using pcsx2 either. My max so far is 49 C. Same with my GPU just in case you think it's bottlenecking my system. GPU max has been 61 C

I mean I guess I could do that as a last resort but I'd rather not have my machine running at max clock all the time :/

I looked at a pic of your board and don't see any VRM heat sinks. If you increased the voltage to your CPU, it's possible they are getting too hot, regardless of the actual CPU temp. Hot VRMs will cause throttling too.

Thanks, I didn't know motherboard could bottleneck software performance. Just ordered 2 sets of VRM heat sinks.

It definitely can.

You can see my system in my profile, for reference. At first I had a board without VRM heat sinks and was having severe throttling even though my CPU was well within temp spec(and on water cooling). After asking about it on Tom's Hardware( http://www.tomshardware.com/answers/id-2...eason.html ), I found out it was the VRMs. I fried the board inadvertently trying to measure the VRM temps with a meat thermometer(Metal probe, I was being an idiot...), and when I ordered a new board I made sure it had VRM sinks. Since then, I was able to go to an even higher overclock without throttling.

PCSX2 is one of the programs that dont react well with intel speedstep some times it will down clock cause it not needed, Which why I have it disabled
