I don't know anything about MSI's bios but I always grab my stock vid from bios (gigabyte).

Just not much of a high clocker.

Tbh the difference in his 4.3 and my 4.7 is not noticable in any game. It translates to about 3% per 100mhz core. I am basing that percentage off what the asus software tells me when i move up or down 100mhz. That 12% is much less apparent in games though.

If somebody can convince me that I just have a terrible CPU and I'm not missing anything, I can deal with that. It's not my computer. I built this for somebody and wanted to become more familiar with Haswell. The owner isn't concerned about getting 4.6 out of it, I am haha. I've got a pretty stable 4.4 @ 1.38 setup for him with C3 enabled so it stays in the .2-.3 VCore range not under load.

Thanks, based on what you said I may not be the only one. I might just close the door on this project now.

from what i've seen on my amd asrock
they like to have the voltage set 0.1v higher then needed
so going by his asrock stock voltage may not be best.


none of that matters though because his haswell pc has an msi board.

That 4.4 oc will serve him well. Not single thing that chip cannot do at those clocks.

Except bench as high as one clocked higher. Which only matters to us on ocn.

Yeah sorry looked at the wrong build in your signature. I would say a stock vid of 1.03v is really good, above average for sure. At a stock vid of 1.07v I can do x45 @ 1.250v all day. There may very well be something else going on that's holding you back. WIsh I had some ideas to toss out but I got nothing atm.

my stock vid is 1.069
yet i cant touch 42x with anything less then 1.20-1.19 vid

I'm having problems with Prime95 v28.3 1334K.
For x45, x42 cache I have VCore=1.370, VRIN=1.950, VRing=1.260, VCCSA +0.270; CPU I/O Analog +0.200; CPU I/O Digital +0.200
RAM is on XMP (1.50 V, 1866 MHz)

It looks like I need a really high VCCSA, because at VCCSA +0.200 I got BSOD 0x0000009c in 15 minutes Prime95 v28.3 1334K.
At VCCSA +0.250 I got BSOD after 2 hours 1334K.
Right now I'm testing +0.270 (HWiNFO shows VCCSA = 1.128V).

What do you think about this high VCCSA. Is it dangerous?
Darkwizzie, you had some problems with BSOD 9c, did you try raising system agent voltage to this level?

You're right. I just get caught up in trying to get the most out of this thing. He couldn't care less about benchmarking scores. wink.gif

I wish it was obvious. I posted screenshots of all my BIOS settings last night. I'm getting the impression I don't have anything wrong. I thought maybe the fact I enabled C3 and not C7, but I have issues even if I leave them disabled.

I think it takes me 1.26 to be stable at 4.2. Of course I don't have a high dollar motherboard either. That might have something to do with it.

Long lost, Haswell brethren?

Yea these CPUs may be twins separated at birth. cheers.gif

I'm going to keep playing with it and when I'm ready to get charted I'll put in my final settings. Things were going really well up to 4.4GHz. 4.5GHz required a bigger voltage boost than the previous steps through the multipliers, but I was at 4.5 with 1.225 VID feeling pretty good about this CPU. Then I started playing BF4 and got a bunch of 124 BSODs. I kept upping VID by .025 until I got to 1.275 and still got a BSOD. I raised it to 1.280 and have been fine since.
