That dreaded 0x101 BSOD

Hello,

I've been overclocking my 2500k since I bought it over half a year ago (I've run it @ stock for like 5 minutes). At first I OCd it to 4.6 GHz, but I've been getting a lot more 0x101s than I wished for and I didn't want to increase voltage any more (Ideally I'd want to run this rig at 1.35v max). Thus I downclocked it to 4.5 and started at 1.30v I think (it was a long time ago), but the 101s didn't go away. I progressively increased the voltage each time one appeared, and they were fewer and fewer of them (once a month or so, and only while playing Diablo 3), but the voltage went to about 1.36. I figured I'll redo the air cooling (I have a Mugen 2), buy new fans, chassis fans and airways, apply new paste and do the OC properly (with dynamic voltage etc.), since it was kind of a ghetto solution anyway - just one stock fan for the Mugen, no proper air channels, fixated on 4.5 GHz, when I could just downclock it to 4.4 etc.

Then my mobo got fried by static (P8P67 Deluxe) and I waited for its RMA for over a month. Now I have a Z77 Sabertooth and I figured that this is the best time to finally do the cooling properly. I haven't bought the new fans yet, so I've set everything to stock (bios -> load optimized values), put in the stock cooler I got with the 2500k (I really don't want to put in the Mugen twice :D) and didn't overclock a thing. I installed fresh Windows 7 x64 on a fresh disk, installed the drivers, updated the OS, installed Diablo 3, played a bit, installed Spec Ops: The Line, played a bit... and 0x101.

How is this possible when everything's on stock? Any hints on how to diagnose it? I always thought that 0x101 was only related to voltage and OC.

My rig:

i5 2500k @ stock
Z77 Sabertooth (latest BIOS)
Gainward GeForce GTX570 Phantom
Corsair 650HX
G.Skill DDR3 8GB(2x4GB) 1600MHz RipjawsX CL7
Corsair Carbide 400R
WD Caviar Blue 500GB (SATA3)

Any ideas?

Try your ram at 8-8-8-24 at 1.5v and see how that goes. Cas 7 ram is pretty tight timings, even though its spec'd for it. The first thing I look at when Im not stable at stock and I have already checked/changed my PSU is the ram. Especially when a fresh install doesn't solve the problem.
 
Oooh! Thanks! I didn't touch the RAM even once, because I wanted a rock solid CPU first. I didn't know that the manufacturer could put in defaults that were too tight. I'll try that.

I did the switch, but I also noticed the default voltage was 1.6. Won't 1.5 be more crash-prone, even with looser timings?

-- edit --

That 1.5v kept crashing Firefox, games and other things, so I upped it back to 1.6. Seems OK for now.

The BIGGEST and ONLY thing that helped me achieve 5.2ghz stable was changing loadline calibration from "EXTREME" to "VERY HIGH" on my Asus P8P67.

I had to increase the vcore offset by quite a scary amount to compensate for underload conditions in order to maintain 1.51v, but it completely fixed all random BSODS.

Been purring fully 100% stable for roughly half a year now both HT on or off, though I keep it off for game performance ~ 5% measurable improvement in high end games.

Hope that helps...
 
OK, since 8-8-8-24 didn't help I set the RAM to 11-11-11-25. Now it seems stable, two days without a single BSOD. I gotta check these sticks later, but so far it seems it really was them. Thanks! :)
