New Machine, but every game lag

Dan93 · Aug 25, 2014

Hello. First: sorry for my bad english.
Second: I have big problem with all games, laggs. Like this in the video. I've tested all components and i change the video drivers with new, beta old, but...... still lags. I've reinstalled windows 3-4 times and still have lagg.
Here some specifications:

CPU: Intel i5 4590 3,30ghz
RAM: 8 GB DDR3 1333mhz 2 x 2 GB and 1 stick 4GB
VGA: Gigabyte GTX 660 OC
PSU: Cooler master extreme 500W
MOBO: Asrock H97 Performance
HDD: Toshiba DT01ACA200
Monitor: LG Flatron W2243T

Well this is a possible cause "Cooler master extreme 500W" those PSU's are absolute garbage, dirty and/or insufficient power(the extreme series can suffer from both) will cause performance issues(and can damage hardware). Even if it is not currently the problem, it would still be a good idea to replace it before it dies and takes the rest if the system with it. Also running ddr3 1333 in single channel mode isn't helping your performance either. In many cases you'd be better off with 4Gb in dual channel over 8Gb in single channel. With that cpu I wouldn't suggest running anything slower than ddr3 1600 with a CAS of 9.

Hello. Thanks for the fast answer.
I'll buy a new Power Supply Fortron Raider 750w bronse. Then i'll write what happend with the lagg.

Done. I removed the 8gb stick.

Single player games or multiplayer? Have you installed something like MSI Afterburner to verify you video card is being properly utilized? Are the tempers of your cpu/gpu ok. If either gets hot, performance will suffer.

It's not how big your psu is - it is the quality. Where do you shop? We can suggest a good PSU for your system.

I had a quick look at the power supply you have its rated at 18a per 12v rail.
The Psu has two so if you combine them that is a toral of 36 amps.

A Gtx 660 card on its own requires at least 24a from the 12v power rail.
Leaving about 12 amps left from the 12v power rails for the rest of the components in the system that need it.
As said if you starve a Graphics card of it`s required amps and wattage. it will limit, or impair the performance of the gpu.
Even with a 500w power supply your close to its limit in wattage out put, because although it states a minimum wattage the card will run at, it does not factor in the rest of the components each system may have in it also requiring power and amps from the 12v power rails also.

This is often the common mistake, because you always work out what the rest of the components in the system also require. To get the true wattage and amp ratings of a sufficient Psu to keep the system stable and rock solid.

Both.

No, i don't have MSI Afterburner.

Temperatures are good. On load: CPU: around 50-55 GPU: around 45-50

Dan93 · Aug 25, 2014

Where do you shop?

Take a look at this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438016&cm_re=psu-_-17-438-016-_-Product
I dont know if the lack of power from a psu can cause low fps (i've suffered from shutdowns only, i learned the hard way) But changing that psu is a must, Are you plugging the monitor to the motherboard or to the gpu? Sounds like your system is using the igpu instead of the dedicated graphics card.

To the GPU. GTX 660.
