Thread Starter 

Well for starters, there are like double the amount of charted Malays vs Costa, just by luck alone Malay should have more in the top.

 

Cyro, I know.

As a Malaysian,
I apologise for the work of my fellow brothers.
We'll do better next time.

Username: Brutus090
CPU Model: 4770k
Core Multiplier:x 45
CPU VID: 1.280
Vcore: 1.296
Uncore Multiplier: x42
Uncore Voltage: 1.150
Cooling Solution: Phanteks TC14PE
Stability Test: Prime 27.9 Custom FFT 1344 1 hour, x264 for 60 passes
Batch Number: 3313B373
Ram Speed: Crucial Ballistix 1600 9-9-9-24
Input Voltage: 1.900
LLC Setting: Highest (can't remember, but definitely not auto)
Motherboard: Asus Hero

I'd like to just throw it out there, although this maybe an old discussion point and no longer on the table, that I would definitely be interested in a second version of the original chart with more "strict" rules about both stress tests and general methodology...while I know getting a vast amount of users to help mess around and record data with their chips is unlikely, even just a solid handful of us using some standardized methods might produce interesting results.

Also, picture verification: Warning: Spoiler! (Click to show)


I have the same motherboard and my settings are almost identical to yours. 45x 1.280v, 42x 1.150v. My Eventual is 1.780v though and I have LLC on Auto. Also the same CPU cooler. biggrin.gif

I have a costa rica 331 that will not pass 4.4 @ 1.36volts. My Malaysia chip does 4.8 @ 1.39. There is nothing constant about which ones are better.

And for a chip to be programmed as K, it must pass the stock clocks and volts + 10% extra. Just as that intel rep said in the newegg tv interview (that they don’t recommend you to go past 10 percent extra)

And you can imagine that when the K quota can’t be reached, they will program some chips that don’t make the cut, as K’s and then ship them to countries where there is a strong NO-RETURN policy (like where i live).

I believe in the newegg video he was talking about 10% in voltages was safe. But for a production line I think it must mean 10% in frequency.

Just to clarify,
I was just saying that it's "seems" like the Costa Rica's batches are better. Most of the users have Malaysian's and even with the vast amounts compare to the Rica's it still shows that they're are better. I was just asking a question. Cos to me it seems that way. smile.gif

I made the correction.
post #11008 of 19539
@Darkwizzie, can you change some values on my chart?

Uncore voltage 1.15v not 1.18v.
VCCIN 1.78v not 1.84v.
RAM voltage 1.65v not 1.7v.

Those are my BIOS settings. The voltages listed in the chart are HWInfo load settings. I think the chart is looking for the BIOS settings, right?

I don’t think he was talking about voltages since there are none specified for the stock/turbo in the spec sheet (and there won’t be since they vary from cpu to cpu). Whereas we already know the stock/turbo frequencies. I think i saw a mention somewhere that the maximum voltage under extreme cooling should not pass 1.5V.

On the video he actually was referring to voltage when he said keep it to within 10%. But I agree, since they haven't specified a voltage, within 10% of what? I would assume 10% of the default voltage at say 39 GHz.
I don't think Intel has specified any maximum voltage. Maybe but darkwizzie will biggrin.gif
