Haswell Overclocking Guide [With Statistics] - Page 992

post #9911 of 19539
Seems that adaptive mode on Asrock might be not the best idea either. Yes, voltage drops nicely during lower load, but I noticed that it does spike kind of randomly. It was fine during C3/BF4 gaming, but then Core 1 had jumped to 1.37 during light gaming (LoL) and browsing. Core 0 just now did the same ****, probably when scrolling a pdf in acrobat reader.

I will monitor it a bit more but I guess I am going back to override 1.29V (testing x45, seems to be stable on this voltage - but x46 was crashing everywhere even on 1.35V)

Core Multiplier: 43
CPU VID: 1.210 offset +.034
Vcore: 1.264
Uncore Multiplier: 38
Uncore Voltage: Auto
Cooling Solution: H105 closed water loop.
Stability Test: Prime95 25.11 smalls 1 cycle. 8k,10k,12k,14k,16k tests. 1 hour 17minutes: No bsod
Batch Number: 3314B754
Ram Speed: 2400 xmp enabled
Ram Voltage: auto
Input Voltage: 1.775(bios) 1.760(bios reading) 1.776(hw monitor) 1.728(under load hw monitor)
LLC Setting: 25%
Motherboard: Msi G45 Gaming

questions/input welcomed.

You mean to tell me things are actually in the OP? What is this? A guide or something?? I'm confused as to why all answers are in the OP.

Thanks Darkwizzie, I found it, I knew I had read it somewhere. Thanks for pointing me to where I read it(wasn't sure if it was affecting vccin or vcore. Also felt you guys would be a bit more friendly ;(....jameyscott. Anyway there you have it, edited my post to info i was unsure about. Thanks again for this great vat of information you have gathered.

I'm just messing man. A lot of people ask the same questions over and over. It's just easier if people read the OP and then ask questions. I'm more than willing to help you and anyone, but I prefer people read the OP so that can learn it themselves. Empower yourselves and rise above stock! gunner2.gif

OK, I can't get any voltage drop with not just C7 state enabled, but ALL C states enabled. My VCore is constant and also everything skips really bad with C7 enabled. Am I missing something here?

Edit: I only get the skipping with C7 and C6, not C3 or C2. Either way it's completely irrelevant if I can't get VCore to drop.

Check whether your PSU has DC-to-DC circuitry, otherwise you can't use C6 and C7. Also do you have EIST enabled?

Also check your power plan in windows to see what your max and min CPU usages are set to.

Do you get the same behavior when you set VID to Manual rather than Override?

Thanks for the reply. Yes it is a DC-DC PSU, a Corsair HX series. I also have EIST enabled. On the MSI board 'manual' is the same as 'override'. So I've got Ring voltage and VCore set to 'override'.

I've tried various power setting from 5% up to 100%.

I have a question regarding x264.

I tweaked my ram timings, was stable 200% memtest and wprime.

However, in x264 when i start a bench, it just stops after 20 to 40% in the first pass, first run.
The program is still active but the bench stops, nothing happens.

Is it my ram timings ?

Tried to revert back to before tweaking (where it was working last night), still same effect, will try to put back to stock...

Realbench seems to work fine
