I guess it's time to play the haswell lottery then.

Thanks for the help.

And XTU's memory stress test heated up the CPU more than CPU stress test. I mean, WHAT THE HECK???

Finally got some time to setup my pc yesterday night. Installed cpu, ram, mobo and cpu block. Boot pc, enter bios and omg, i see stock vcore 1.198v. Set mem at 1600/1.65v/auto, vcore at 1.3v and cpu at x45. BSOD (124), get back to bios, set x44, boot fine, start boinc bsod (124) after 5 min. Back to bios again, x43. Start boinc, bsod (124). Set x42, vcore 1.285v, mem 2133/auto, running boinc for 9 hours, max temps 80c (ambient 27c), now at work, hope it doesnt crash while i m away, lol. Regreted i sold my ivy. This chip is going for sale today, i ll try my luck again.

You didn't even set VRIN properly or manually specify uncore etc

Like you said VRIN is at stock and uncore is at 4Ghz. But honestly how much difference will this make? I dont think this chip is able to run at more than 4.4Ghz@1.3v. This was my first look at this chip and i never said its a solid oc, i ll work with it later today. But if it cant even enter win at 4.5 with 1.3v, i dont think changing every setting in the world will help me to achieve this. Correct me if i m wrong though.

VRIN is freaking huge in Haswell.

It probably won't. I have the exact same problem. I've run RAM at stock to 2400, cache down to 35, etc. I've slowly tweaked and worked with VCORE, Input Volt and Cache Volt, X-Talk Cancellation, etc. It made little difference. Tweaking it since launch and 3 BIOS iterations later, I got the "reverse lottery" on Haswell and anything above 43 multi requires voltage above 1.3 volts (silly) and even then I get x124 BSOD and my temps are well in check. I would say even at 43 it's barely stable. 42 @1.23v, rock solid. LAME. So I guess I was unlucky and struck out. (oh and I tried it on two seperate boards as well. A Giga and Asus. The ASUS being my primary board.)

I'm going to keep it though and hand it down to the family as a good general use computer as their computer needs replacing anyway. It's a fine CPU for this, but it's no enthusiast proc K or no K.. I may even go AMD just for kicks, who knows; it's been a while since I've trried the "red team" (Athlon FX-53) and I don't care about the loss in IPC. Video and gaming is about all I do and again, I must admit, I'm kind of irritated with this Haswell as an enthusiast. The variation between samples and retail is, I believe, unprecedented. It a fine proc, but as we all knew, this is no enthusiast proc, but I grew anxious to build since I was a 920 C0 guy and hadn't built anything new since 2008 / 2009. I kinda wish I still hadn't .

re-seated , applied new TIM instead of standard on my corsair h80i , stress tested cpu to get it heated up and now back at idle between 32-33 which is hella lot better than 40

mind you its OC'd to 4.0 @ 1.050vcore with Vrin Override at 1.5

It might be corsair uses shin etsu on their coolers, but god knows how long that h80i has been on that warehouse before it got sold to me etc.

It is well known that attached thermal paste is a piece of ****. I never used paste coming with cpu or gpu cooler. Aftermarket are hell way better.

True true, but "supposedly" Corsair is using Shin Etsu on all their coolers which is supposed to be among the top TIM's in the world, but i like my MX products way more ill admit.
