Hey, guys. I have an asus m5a78l m lx/br, an fx 6300 fps, a Corsair CX 500 Plus Bronze PSU and an Saphire r7 250 8GB RAM.
All of sunden I hv FPS drops in ANY GAMES (even old games) at random times. Sometimes im in heavy load graph places in games and I dont hv the FPS drop and sometimes in smoother place i do. What im trying to say is that it looks random.
I have seen some people trying to fix the incompability between that MOBO and FX 6300 saying to manage volts and speed clocks on the BIOS. They say that automatic configs in that MOBO are based on a 4.0 Ghz and advice to make some changes in the CPU Jumperfree config in BIOS. Others say that the VRM of this MOBO heat too fast with FX cpus. ASUS says it supports them tho.
So my questions are:
1- Would there be a way to find out WHAT is causing the issue? It could not be the MOBO, but the CPU or even the VGA (i try to focus on the mobo cause there are more information about issues between that MOBO and FX cpus)?
2- Would make sense to try those changes in BIOS? Changes are : Set CPU Overclock to manual and set CPU base frequency in 200 and multiplier at 17.5x (3.5ghz). Is there a way to find out if the automatic settings for my MOBO are indeed unsupported for the FX 6300?
3- Important info, this MOBO socket is 760G (RS 780L). Would that matter?
4- Do you guys think its more likely to be an VGA problem?

Things I've already tried.
-Set power Limit in afterburned to +13 / +20 (SEEMED to hv a better result at +13)
-Installed a bunch of FANS and an Aircooler for the CPU (Hyper TXT EVO / COOLERMASTER)
- Tried to overclock VGA and tried to downclock it aswell. Didnt see any changes.
- Since I installed fans and aircooler i monitor temps constantly and im always good in thermal margin for the CPU (actually most of the times a lot far from that to be an issue) and VGA had NEVER gone too hot.

How the FPS drops:
Im playing anything at 60/80 FPS and all of sunden it goes down to 2~8. SOMETIMES alt tabbing real quick fixes it, sometimes it doesnt. Sometimes opening in game menus works 2, but not that often as alt tabbing real quick. Sometimes multiple alt tabs do not work at all and I hv to restart the game. Sometimes takes weeks for that to happen, sometimes happens over 10 times a day.

Games i've experienced that:
Elder Scrolls Online (not so much, but it happens).
Dota 2
Heroes of the Storm
Archeage
Dragon Age Inquisition
The older Dragon Age games
The Witcher 3
Tera

Im sorry for this wall of text, its just cause it seems like a too specific issue. I just bought an MSI R7 360 just to find out if the VGA is the problem, its about to be here in 1 week, lets see... However, if thats a MOBO / CPU thing, the VGA might not help at all.

Thx for reading.

This a single module that when combined with another is not a matched pair tested at the factory. Unmatched pairs not bought in a single pack may not perform well.

page 2-11 of English manual
Memory Clock - a setting of 800MHz equals a memory clock of 1600MHz (at Double DRAM Rate - DDR)
DRAM Timings
You can manually set the first three numbers beginning with CAS Latency.
The Kingston .pdf indicates DRAM Timings of 11-11-11 for one module. Running two modules Timings could be something different.

So leaving memory clock on [Auto] probably runs at 1333MHz. which would give less than ideal performance.
AMD FX Series CPU on that motherboard supports up to DDR3 1866MHz as its standard memory frequency.

You don't mention anything about your memory hardware or if you know what the memory is currently running at.

The 760G chipset is low-end model. Motherboard has no heatsinks on VRM.

The Sapphire video card is limited by 128-bit Memory Bus which will slowdown FPS in intense graphics. A 256-bit Memory Bus or higher would be a big improvement as would the 970 or 990 chipset motherboards. Memory Interface for MSI R7 360 is also 128-bit.

Memory settings are on auto in BIOS. i hv 8 GBs (4+4) 1600 MHz.
Anything I could do about the VRM? I heard there are some adesive dissipaters i could put on the VRM, but i cant find a video showing how to do it.
I'd like to know what is more likely to be the reason of the problem.
