Yes, sure seems Prime95 is a PITA. However I am inclined to trust that if it passes, the system is stable.
Not completely sure I'm ready to say all Prim95 failures with the FX are stability related. But I'm running it with stock settings (minus all power saving stuff) just to see how it does.
I will download OCCT also.
2: BIOS F9 managed to mess up LLC. If you would like to try it, I have a copy of the F9e BIOS where it does work.
In what way is the LLC messed up in F9 ?
I would prefer to get my BIOS from Gigabyte as I have messed up boards before and it's very painful.
I'm running an FX-8350 though so I don't think I can go to older BIOS than F9.
3: Sorry to say it, but Giga is kinda iffy on the whole FSB thing. I think one guy with a UD5 got a FSB clock to work, otherwise Giga has been pretty much all-multi.
Well, I have made some progress with the FSB OC. It's all OK with IBT. But that's just too short of a test.
With prime95 it still failed at 240 or 260 FSB. I haven't been able to go to 280 or 300 FSB, but apparently some people have run it according to the first page of this thread. Though maybe not with the Gigabyte mobo.
4: Dunno if you're giving the board enough time, but a failed OC at POST, it'll reboot with "stock" on it's own and give you a heads up after 20 seconds. Also, when you have the settings you want, press F11 on the BIOS "home" screen, and save your profile. You can save up to 8 different setting profiles. When you need to get them back, press F12, and chose the profile.
I'm giving it plenty of time. Even power it down unplug the PSU from the wall for some time, until all power is gone. But sometimes it just won't come back if the BIOS settings are too messed up. A few times when I messed up the settings, it kept rebooting itself, I would hear the fans come on full speed for a short time. But never got to beeping or displaying anything. Those times the only thing that works is the screwdriver to reset the CMOS.
Lets see, settings...
CPU: 5000Mhz (x25)
NB: 2200Mhz (x11)
HT: 2600Mhz (x13)
RAM: 1600 (x8)
RAM timings: 10-10-10-27 1T
What kind of cooler are you using ?
1.5V seems a bit high for my air.
Though your settings do work and let me boot windows. Just can't run P95 stable with them.
My RAM timings are 9-9-9-24 as per Corsair.
CPU PLL: 2.695v
RAM: 1.515v (theres some vdroop, the extra .015 compensates for it)
OK, will play with those 3.
Why do you keep the CnQ on but turn off all the other power saving features ?
For OC testing don't you want to have all power saving features off ?
Want something more complete, I'll give you a copy of my BIOS, and you'll get my profiles with it.
Any other questions?
This was what I was looking for, thank you !
