Damn, seems like a hell of a lot of volts for that clock speed, I'm currently doing 4.4GHz at 1.246v which seems stable for me over the past couple of days, I might be able to drop it a few 0.001.
Have you tried overclocking from your bios instead of Intel ETU, and what's your input voltage at?
^ Hah, you're telling me! Before I OC'ed the G3258 I was reading everyone else's results and I was sure I could hit 4.5-4.6 with an EVO212 at similar low voltages. Seems like my CPU and/or mobo disagree. My case has the left side open and I do have 5 case fans going on (2 cpu, 1 exhaust, 1 bottom case intake, 1 front intake) so I thought I had adequate air flow.
What's input voltage? I believe if I'm asking the question I just left it at the default (which may be a big no-no) setting.
The MSI OC interface isn't exactly intuitive - either that or I'm pretty slow - so I avoided that & their OC Genie (presets are disturbingly off-base).
Not saying the ETU is the best but I liked the ETU as I could switch over to teh internets quickly to search threads/posts for help. And when you're done making an OC profile that benchmarks/is stable on ETU, you can upload it to their website to cross-compare to other guys with the same CPU and/or mobo. I've seen and downloaded other guys' settings to see if they would work with mine (most do not unfortunately).
You're not alone. My chip needs about the same 1.38v for 4.5GHz to be fully stable or I get RSOD when gaming... anyone else had this with the G3258.

^ I am commiserating with you right now. Although you did get to 4.5 stable - I'm stuck at 4.4.
I'm sure if I went to 1.4 or above I could get to 4.5 but as seeing other people's results on the stock cooler and lower voltage......it's likely I've got a dud here. Or else user error which is probably the culprit.
I wish there was more consistency with CPU's. Every Sandy Bridge CPU I had (lots of them) were very consistent with their clock to voltage ratio. Ivy and Haswell are all over the place. The G3258 I had was rock solid 4.5 @ 1.252 (1.25 in bios) using the MSI PC Mate board from Microcenter.
^ Yes, I agree completely. I haven't bought a new computer since mid-2008 with my Q6600 and while reading/researching the past few months it blew my mind there's a silicon lottery when it comes to the intel cpu's nowadays......and I'm drooling at your OC stats. How are you OC'ing - BIOS, OC Genie, or Intel ETU?
Do you know your cpu batch # and where it was manufactured (found on the retail box UPC)?
I happened to have done Skyrim Benches the otherday, It was a slightly modded game but I can do a Vanilla one once I find the files, fortunately I had the Warzones mod enabled at the time so I came across a raging battle, and also took on a Dragon a few minutes after.
I've given Borderlands 2 a test, it ran well on max settings, however I feel PhysX may have had an impact on the performance, I'll try and get two videos up, with PhysX on High and PhysX on low. Update on games
Grand Theft Auto 4- Runs like crap, quite surprisingly
Max Payne 3 - Singleplayer runs great, Multiplayer too however I haven't found a full match yet to truly stress the CPU
Skyrim - Runs well
Borderlands 2 - Runs well
Sleeping Dogs - Runs great
Tomb Raider - Runs well
I've did a bit of Natural Selection 2 but I need to test it further.
State of Decay
Of most of the games I've tested and I'm yet to test I'll try and get videos up, alongside an FPS sheet.
