More voltage needed after BIOS update? (3770k)

post #1 of 3

(This is a wall of text. I apologize but I hope the story will give some more info)

Hey guys! I have a quick question with some possible help needed.

Here's the story. Recently, I added a second GTX 680 into my rig and wasn't able to SLI or even boot into my computer properly. So after some deliberation and thinking, I realized that I should maybe update my BIOS (F6 to F15"o" Beta on the Gigabyte Z77X-UD5H in my sig rig) so that it could detect my PCI slot in use. And voila! It worked. I reset my old voltages (1.24 with LLC set to Turbo) and settings back to my previous 4.5 Ghz clock, and I was set to go.

I never really encountered issues, other than a single BSOD in Witcher 2. However, as of late, I have been experiencing BSOD's very frequently. Now, I became extremely alarmed (as I always do) and decided to look into my issue. Well, I found that I had my RAM in the incorrect slots and placed them back in and my problem went away for quite some time. Until today.

I decided to refresh my Windows Index score just for fun and the program crashed on me! I then proceeded to run Prime95 and couldn't make it past Blend Test 4 of the 400k run. So, I thought that maybe it could be the RAM acting up again. But after readjusting, it didn't help one bit.

So I went to stock and enabled Prime95 again. I got through 45 minutes easy (it didn't crash, I just stopped it at 45). So, I went to redo my OC and raised voltage from 1.24 to 1.26 and boom. Hour and a half before I stopped it manually.

So, now for my question. Can a BIOS update change the required amount of voltage for a CPU? The BSOD's are a bit random, so I'll report back if it happens to occur again. But can a simple update really change that much about a mobo?

Thanks in advance, and please, any questions or info needed, just ask biggrin.gif

Sometimes it is possible that through updates the readings change slightly to be more accurate. But there are also other possibles:-
1- The OC wasn't stable from the scratch, but just you were lucky enough it didn't crash on you all that time.
2- The chip has degraded slightly.

Maybe I was lucky biggrin.gif

Thanks for the reply though! Should have considered the degradation factor. It still runs like a champ, but it has been in this rig for quite some time. Hopefully Broadwell or Ivy Bridge-E helps with that hehe
