Intel Pentium G3258 Performance and Owners Club NOW with GTX 970 - Page 144

post #1431 of 4581
I think this test is broken smile.gif When i convert x264 in my way (Megui and my presets) everything is good xD

h264 is harder than prime95 for sure, people report +0.05v vcore for stability, also try increase your vtt by up to +0.2 its fine.

Took me a while to dial that in also but a 9c is you need more voltage somewhere (same with 124). I'd start with more vcore and perhaps more vccin.

Not sure why this isn't a sticky in every overclocking-capable CPU owners' club, but here's a list of BSODs and how to fix them. Also, Prime won't be very demanding due to the Pentiums lack of AVX support. This has been brought up over and over, and should ALSO be mentioned in the initial post. Maybe a "Here's what's different about OCing G3258, here's how to stress it, and here's how to fix it when it crashes."

I've been getting a few 9c (Machine check exception) lately - solution was decreasing VTT. Running Samsung rams at 2666, I started out at +.036V. +.038V worsened the problem (almost instant 9c), +.032V now running close to an hour in 640k (in place)

Of course every chip behaves different, but maybe this helps you.

Oh, and slapping +.2V VTT on the poor chip sounds pretty horrible, I wouldn't do that for 24/7 operation. Even at 2666, I've never seen any benefit going over +.045V VTT.. been testing 7 pentiums now.

do u have some method to check if cache clock is stable? or i just have to run x264 stability test too?
post #1437 of 4581
Can you help me with my bios too? tongue.gif Maximus VII Hero
I dont know what some voltages do:
1. CPU System Agent Voltage
2. CPU Analog I/O Voltage
3. CPU Digital I/O Voltage
4. PCH Core voltage
5. PCH Core voltage
6. VTTDDR Voltage

Thanks smile.gif

Told you before man tongue.gif
512k and 576k, in place, 30mins each.

VTT which I wrote about would be Analog I/O Voltage + Digital I/O Voltage.
VTTDDR always at half of VDIMM
PCH don't touch, basically.

can i ask why actually these two? some kind of secret test? xD

these tests stress the cache the most. nothin' secret, otherwise I wouldn't be telling you biggrin.gif
