FWIW, I have found 20 loops of x264 and 5 hours of BF3 to be a great stress system. Nothing causes a cpu crash after validating with those and I've done IBT to folding.

it only runs for 4 times whenever i start it. so i have to start it again if i wanna test more.


woops. i found it. sorry.

I have a few questions about your overclocking guide because you don't hit all points. Do you recommend overclocking all cores the same multiplier or using and taking advantage of speed step or aka turbo boost frequencies. The second question I have is why do you not touch on ram that much. From what I see you suggest to set your ram to 1600 MHz and call it a day. I didn't buy expensive ram so I could lower its frequencies. I get core is kind and having a higher core clock vs high speed and ram timings is definitely better but you don't mention anything about going back into ram values or trying to find a balance. My chip right now got memtest errors and I believe it related to my overclock due to the integrated memory controller on the cpu and my overclock. I am using 1.2 voltage and have 42x,42x,41x,40x, as my boost frequencies. Now having 1.2 as vcore might be the cause of instability. That and Im running my ram at rated timings that I purchased them at. So either my CPU really is that bad that 4.2 ghz at 1.2 wont work, or 4.2 @ 1.2 and my ram timings don't mix well. Would that lead me to believe I can not run any overclock with my rated ram timings and i'm forced to lower my ram speeds ? All my other settings are put as you suggested such as keeping uncore and ring voltage to default. So this really has me confused that my chip would be unstable. I say it could be CPU and not ram because I tried each stick individually running failsafe mode on memtest which test with only one core on cpu and each stick passed individually on all slots. This really confused me. So I put the ram back where they were originally backed off overclock because I thought timings ( the regular default xmp values) were to aggressive for my CPU and NO ERRORS found. Also the other issue I have seen that you say is to not mess with LLC, but on gigabyte boards even check with SIN, any thing other than extreme on any overclocking scenario at least for me crashes and doesn't respond well. I have found if your overclocking to set LLC to extreme at least on gigabyte boards and you will be more successful. Even a mild 4.0 ghz overclock without LLC causes instability at least for me and my board on ud3h. Vdroop could be causing my instability for my ram and cpu. I also noticed power phases are important for overclocking especially on gigabyte boards.

HW Monitor @ idle
VIN3 = 0.864
Vcore = 0.720 (Max 1.312)
VIN5 = 1.760
VID = 0.790 (1.302)
IA = 1.331
GT Offset = 0.0
LLC/Ring = 1.306

CPU_Z
Core Voltage = 1.760

AiSuite 3
Core Voltage = 0.720

HWInfo64
Core Voltage = 0.717
VCCIN = 0.88
VIN 1 = 1.008
AVCC = 3.328
3VCC = 3.328
VIN0 = 1.008
VCOREREFIN = 1.976
VIN4 = 0.352 (0.648)
3VSB = 3.440
VBAT = 3.312
VTT = 1.120
VIN6 = 0.864 (0.872)
VIN2 = 0.352 (0.648)
VIN3 = 0.360 (0.648)
VIM 7= 0.360 (0.656)

What wud really be helpful is a table that list the terms used in this thread, with what we see in the various utilities, as well as how they show in the various BIOS from each manufacturer.

Taking a quick shot at it .... something like this

Voltage.XLS 10k .XLS file

If any posts data, expands the terms, I'd be happy to update the file.

1. Different multipliers has been discussed (admittedly hard to find in 700+ pages), its also in most of the vendor videos .... but yes its worth investigating..... the MSI video linked 'somewhere in this thread also touches on the subject in some detail.

2. Speed step etc. is discussed throughout the thread. Same logic applies with turning off things t rule out variable... But I decided to take a shot at it and made almost no changes to BIOS, leaving everything at defaults and climbing to 4.6 .... as that was my goal, and I had gotten there with minimal edits, I didn't go back and see what effect was disabling anything. Your mileage will vary" and I just pretty lucky.

3. Yes 1.2 vcore is kinda average.... i was stable on the 4770k on BIOS 0804 (all cores and cache same value) .... BIOS upgrade killed 4.6Ghz but haven't had tome to tweak it yet ... may roll back.

4.2 GHz - 1.152
4.4 Ghz - 1.275
4.5 Ghs - 1.320
4.6 Ghz - 1.375

3. For RAM, the historical recommendation has always been to OC with lowest RAM setting so when you run into a problem, one less variable to consider....after OC is locked in, then bring ya RAM up so if it trips, you know exactly what the problem is.

4. I'd suggest leaving RAM and cache at defaults and bringing up voltages to make ya system stable under temps ya willing to accept. Once that's done, bring up ya RAM .... once that's done, bring up ya cache....till something bombs.

In responses ... suggest breaking post into paragraphs as one big chunk can be hard to read.

I guess from what you said is strange. I get lowering it for testing. Then you say to bring rated values back up. That is my issue is the rated values are interfering. So if i'm stable at say 1.2 at 4.2 GHz and lowered ram to 1600, if I raise it back to 1866 u get instability. My point is even after testing if 1866 doesn't fly well and those are rated values and I paid for that but can't use it. I feel cheated. My point is your saying to up it back up but the issue is its more stable lower.

I thought you were trying to accomplish OC'ing your CPU.... so to my mind "getting that outta the way" and finding out what y a CPU limits are should be the 1st step....then worry about how to get DRAM to run at rated speed.

Step 1 - Determine your CPU OC adjusting CPU related voltages and other settings accordingly.

Step 2 - With step 1 out of the way, THEN determine how much extra DRAM voltage you need to make the RAM stable.....I needed 1.675

What is your DRAM voltage setting, mine is AUTO ..... I tried 1,65 and 1,66 and wasn't stable at higher OCs.

What RAM are you using ? I have had 0 issues with Mushkin RAM not maintaining XMP settings in almost 20 years. They use Hynix memory modules which are considered the best available. Corsair has been almost as good....they were using Hynix originally in their DDR3-2400 Vengeance Pro line but newer versions were not Hynix.

And while I will buy 2400 RAM in a heartbeat because I use programs that benefit from it and its almost the same cost .... RAM speed is secondary to core speed....if ya have to choose between one or the other, I'd go with CPU.

You haven't mentioned how you are controlling voltage (manual ? , Adaptive ?) , your temps or how you are cooling so we're a bit limited on how to respond.

Your right I get what your saying and that is my goal, but i guess I am past that i was stable at 4.2 before I upgraded ram. So now Im certain ram is the issue and my point that was confusing was memtest error were given, but when tested individually no errors found. So that is what lead me to believe my overclock is the issue, and that 1866 even though rated is to aggressive for 4.2. now that i'm at my overclock there is no figuring out how to get to 1866, I want to unless you know a few ways to accomplish this, I have not raised ram voltage yet because 1.5 is rated and i'm at rated speeds. So i'm running into issues getting the ram where I want it which is default speeds of 1866.
