I'm getting some kind of stutter under heavy load and it has been suggested that I enable LLC, is this the case even with stock clocks?
Also I have 10 steps of LLC, where do I start...

Thanks
 
Well, stutter could be from anything. Start by giving us your specs and elaborate on the "stutter".

You could try the LLC steps by going one step higher every time and seeing if it helps. If you see no difference all the way to step 5, forget about it.

On your CPU LLC can actually overvolt the CPU, so be careful and monitor the volts too.
 
It's a kind a stutter that I only really get when I start a game up, sometimes it can last quite a while sometimes it lasts for a few minutes, temps are good and nothing is overclocked anymore.
I acquired a cpu and mobo from here and have had the stutter since, I've tried oc clock/stock v, oc v on a stock clock, heavy overclocks...

Stock clock 2500k on a z68mobo with a known good gtx 560-Stutter

OC'd 2500k same mobo and 560- Stutter

Stock 2500k stock 7950- Stutter

Varying degrees of OC on the CPU and stock 7950-STILL STUTTER

Any ideas?
 
Here's a video of the stutter. Once it starts even if I close the game down and all other programs it still does it generally for 5-10 minutes.


Full spec:

2500k
Gigabyte Z68-UD4XP
Team Group Elite 2x4Gb 1600 Ram
His 7950
Samsung 840 250Gb SSD in AHCI mode
Samsung Spinpoint F3 1Tb HDD
Corsair 550w PSU

All running stock clocks and voltages, Load temps-CPU 46*C max and GPU 68*C max

Any ideas...
 
Have you checked that your running latest drivers etc?

Is there any way you could try a different GPU?

Does the z68 board support Lucid MVP if so check in bios that its set to hardware GPU an not on board.

If that's all set up fine try taking the gpu out an running from the igpu see what results that gives.
 
I installed the latest drivers for the 7950 twice and Stulid off here flashed the mobo bios for me so that it would support the sandy chip when I bought it off him.

Do you know if I should have to play with LLC on stock clocks?
 
try manually setting the bclk to 100

idk if you have these settings but try enabling xmp profile for your memory

set vcore voltage response to fast and pwm phase control to extreme performance (again idk if you have those on z68 but worth a check)

also set the power control slider to 20% in ccc/amd overdrive (for the 7950)

then see if stutters still occur
 
See if it happens when a game is on the HDD. (that way can partially rule out the SSD). Take note during any pauses if the HDD light is active.

To be honest, you are approaching this all wrong anyway. Start with the symptoms and post accordingly.

I'll have a dig in the BIOS and let you know, thanks for that.

I was just watching the F1 highlights on iPlayer and it started doing it, only HWmonitor and Chrome were open.

I'm a fitter not a computer tech, the symptoms are that it stutters (see video) I don't know how else to approach IT faults :confused: What would be the recommended approach?
 
Wazza-I've set the power control slider to +20% Seems to run hotter now and the auto fan profile is horrific so I've added a user defined profile, will see how that handles temps.

I've set BCLK to 100 but I don't seem to have XMP or Voltage response or phase control.

I've had 10 minutes on Saints Row 4 and so far so good (although the game is still **** :/)
 
set the fan speed manually,around 40-46% for me on 7970

the power control doesn't add any voltage it just raises the thermal limit

some cards need the 20% some don't just luck of the draw

(edit you might get away with just 10%) you will need to test
 
it fine and normal

I have one 7850 that needs 10% or it will crash in games at stock clocks,and another that's fine on 0%

maybe each cards asic quality has something to do with it idk
