I had a perfectly stable 2180 (OC'd to 3.2 GHz), and upgraded to a new 8400. The 8400 is OC'd to 3.8 GHz, but I am having some stability problems, and haven't pushed the OC any further. 4.05 GHz would be nice eventually though. I am now trying to narrow down potential problems.
Does the OS affect system stability after switching processors? Would a fresh install help with stability?
Symptoms:
■no BSOD
■either the system spontaneously turns off (then reboots) or
■the system freezes for a second or two, then turns off and reboots (e.g., happens during BF2 videogame, where screen freezes, sound effects distort/freeze)
■more frequently BF2 simply crashes in the middle of the game (i.e., spontaneously turns off), but without otherwise affecting the rest of the computer (applications). I think this issue may be more BF2-related as it has happened (but very rarely) prior to the 8400, but it now has happened about half a dozen times in the last month or so.
I let memtest run a couple of hours, as did Prime95. No trouble.
Heat doesn't seem to be a problem. (One core is about 5 degrees warmer than the other. They average around 37 and 42 degrees respectively, but don't go much over low 50s during stress testing). Temps are consistent, via RealTemp, CoreTemp, and SpeedFan, adjusted for conservative TXMaxx of 100 degrees).
Temp1 is pretty high though. I thought that was my Northbridge temp, but don't know for sure. With the e2180 it hung between 34 and 38 degrees, and never much higher. Now it idles around 40, and goes up to the low 50s during stress testing. Temp2 is about the same as before, idling at 32-33 degrees, and not changing regardless of stress testing. See from my stats below, that the system is well cooled.
■9 x 423 MHz = 3806 MHz
■VID 1.15 (via RealTemp)
■VCore at 1.32, 1.31 after VDroop.
■VTT at 1.37.
■NB at 1.5.
■SBI/O 1.7.
■VMem 2.2 (2.16 with droop).
■2x2 GB RAM, with timings on Auto for now.
■Bios v.1.8
I have played with about every parameter I know, except for reinstalling the OS. From a previous experience with a single core FX55 to a dual core X2 4200, the reinstall was the ticket. Could that be the case here, or am I missing somthing else? Let me know if you need more info.
Thanks for your help!
