Intel Core I7 2600K - BSOD after 1 month of stability - Page 3

post #21 of 53
the 0.5 voltage difference has been confirmed by intel to be non issue with sandy bridge bro, im not sure where, but I saw it for sure, probably somewhere on these forums.

That said. 1.15 vccio should be fine for sandy bridge, but over that, I dont know.

I dont think there is reason for high vccio unless you have 2133 ram. My ram runs fine at 1.08 vccio.

also, Im pretty sure x124 can happen with too low vcore on these sandy bridge chips

i wouldnt go past 1.2vccio (or qpi on some boards) for 24/7 usage. and i completely forgot about ram speeds

generally for less than 2133 ram, you shouldnt need exorbitant amounts of vccio or dram voltage.

and, i find that the .5 difference helps a lot in temperatures and in stability. at least on my side.

MSI states not to go over 1.4V on the I/O, but I probably wouldn't go beyond 1.3V. I was able to reach 4.8 GHz stably just by upping the I/O to about 1.25V, and the SA voltage to about 1.125V.
I think I might try upping I/O to be honest. Tried to add some more Vcore and it seems more "stable" at the moment. Did about 70 runs on IntelBurnTest.

Thanks for the tip!

I doubt your chip degraded, you were just on the very fringe of stability

also, vccio is tricky, If youre not stable at 1.1 vccio, I doubt its a vccio issue.

1.05 is default

for a 4.5-4.7 overclock. you shouldnt have to raise vccio, if you have to raise it, it should only be a little bit.

vccio is for ram mostly, really high ram clocks like 2133 with 8 gb.

dont ever touch system agent voltage, anyone who tells you to raise it isnt very informed

also, prime 95 doesnt work well for sandy bridge processors, it just doesnt. You shouldnt have to run a test for 24 hours to check for stability.

Just run tf2 with 32 bots, if you can run that for 24 hours, youre stable, and you wont have to heat up cpu to 75c
My RAM speeds are set to 1600 MHz wich is the stock speeds, and even tried Memtest86 with no errors so yeah it's some of the other settings.

I will try adding some I/O voltage if it happends again. Ran 70 IntelBurnTest with no BSOD so I will keep testing!

Thanks for the tip

If I played BFBC2 over 1 month for hours with not BSOD at all that is stable for me.

Now it just randomly dying at idle or even doing anything really. Sounds like a degrading chip to me.

Degraded a bit is my guess. Mine sure did. I used to run 4.5ghz stable at 1.275v when it was new but now it takes almost 1.3v for 4.5ghz (IBT at max 20 runs). It's almost like these chips have to break in or something.

Anyway, now 4.8ghz requires so much vcore I've basically given up and settled for 4.7ghz 24/7...
