post #9501 of 19637
Hey guys,I'm having issues with my RAM that I wasn't having back on my 3930k. DDR3 2400 booted just fine on the 3930k, but after replacing it with a 4930k, it won't post at all. It hands me an Error Code 67 on the mobo, but thats it. Any ideas?

I tried upping VCCSA to 1.2v and VTT to 1.1v, but no luck.

I just did a little searching for that error code. Are you sure that the error code is showing a "67" and not a "b7"? Code 67 is apparently CPU-related, whereas "b7" is RAM-related.

Positive that its 67 and yet the CPU is just fine. It's been in two computers so I'm sure its not faulty.

Have you tried using just one stick of RAM and testing each of the ram slots individually? It could be that one of the slots went bad somehow.....

Thats possible and I'll have to try it out in the morning. If that doesn't work, then the guy I bought it from is going to RMA it, send the 3930k back as a temporary, and then we'll trade back CPUs when the new chip comes back.

Large post. If you re-start a war I will re-block you. I don't mind you being critical, there's a difference.. so that said, I'll play "let's give Prime an opportunity" to try and help, version I'll be using is 27.9.

Current stable settings are (brackets is what HWInfo reports, latest beta version):

VCCIN: 1.95v (1.968v)
VCORE: 1.34v (original start values: 1.344v - 1.36v, set to manual for this exercise)
CACHE: 1.23v (1.274v)
RAM: 1.65v (1.662v - 1.665v)
BCLK: 101.0

= Multi x45 and Cache x42 and RAM 2400MHz @ CAS10 1.65v + BCLK 101 with HT obviously kept on. I won't use "in-place" as I want to ensure there is at least 1GB of free RAM (I'm setting it to 5.5GB)

Results: (Click to show)
Prime 1344 FFT: Instant 101 BSOD.

Dropped RAM to 1333MHz, kept BCLK @ 101

Prime 1344 FFT: WHEA BSOD within Test 1. No BSOD code recorded, assumed 124.

Raised vcore up by 0.02v to 1.36v (1.376v)

Prime 1344 FFT: BSOD 124 in Test 4.

Raised vcore up by 0.01v to 1.37v (1.392v)

Prime 1344 FFT: 1 thread fell over in Test 4, 5 seconds later BSOD 101 in Test 4.

Raised VCCIN up by 0.05v to 2.0v (2.016v - 2.032v)

Prime 1344 FFT: 1 thread fell over in Test 4. No BSOD, stopped the test after 11 mins.

Raised vcore up by 0.01v to 1.38v (1.408v)

Prime 1344 FFT: Prime executable fell over. Rebooting, trying again. Prime passed 10mins
.

Raised RAM speed to 1866MHz, kept BCLK @ 101

Prime 1344 FFT: BSOD 101 in Test 4. HWInfo reported +20W more power usage (~158W), temps went up >5 degrees.

Raised SA, IOA/D by 0.2v

Prime 1344 FFT: BSOD 124 in Test 4.

Raised vcore up by 0.01v to 1.39v (1.408v, one core running 1.428v)

Prime 1344 FFT: Prime executable fell over in Test 8. Rebooting, trying again. Computer rebooted in Test 8, no BSOD Code. Temperatures are out of control.

Unable to continue further as inside ambient temps are now @ 32 degrees and CPU cores are reaching 98 degrees. RAM speeds are still far below 2400MHz and each step will make Prime run hotter.

Screenshot of the pass when RAM was still @ 1333MHz + BCLK 101.0. As per spoiler, this required: 1.38v vcore and 2.0v VCCIN (refer screenshot for actuals):


What did I learn or what can anyone else gain from this, little to nothing IMO. Prime runs hot, already known. That's a 10min run and that's it, change the FFTs and it will run hotter, already known. So if I based my whole OC experience on Prime I'd either have to sacrifice RAM speed so it runs cooler or use a lower Multi (in either case, I will have to obviously run higher vcore).

Question I have is, where's the benefit? If my starting values at the top were stable for the use I demand, then someone will have to show a benefit in increasing from that. If you ask, are you Prime stable the real question is: what do I gain from that; show me how my CPU is failing calculations and therefore being restricted/throttled by my lack of volts.

I personally don't advocate or fall under the group who believes x264 is the bees-knees, I don't use it. It doesn't make you BF4 stable for example and it takes too long to run overnight etc. I do however trust few other programs which are fast, such as multiple runs of XTU Bench (not Stress) and ROG RealBench.

Anyway, as I said.. long post. I do hope it helps you in some way but for me, being thermally limited and not seeing the benefit, I still believe Prime is not the tool for HW. That's my opinion and like x264, I don't mind if others disagree.

Yeah, it's stupid that Intel didn't stick with one numbering convention.

I know there were reports previously of BF4 being crash-happy. Has that been sufficiently addressed for BF4 to be relied on for judging 'game-stable' OCs? I'm contrasting this using something like say BF3/Crysis for testing 3D-stable settings.
