Will see if i go hypers at 2000ish 7-7-7, or psc at 2300 7-10-7
Hope to come not too far for global
I think G470 is better because of higher multiplier (if I'm not mistaken). The CPU needs to be fairly good on air/water in order to gain just a little bit on SS Mine benched x265 and XTU at 107.5 with aircooling and went to 109.5 on SS. You need to tune the BCLK skews in order to max it out, find what's best for your CPU. Also tune the voltages, for example mine doesn't like system agent voltage higher than 1.1V. For some reason VCCIO helped with stability when I set it at ~1.18V.

After 108 bclk I started encountering some problems with the 1:8 divider, no matter what RAM timings I was using. I spent a LOT of time and managed to get it stable for XTU @ 109 bclk, after looping XTU for 3 times though, system crashed again Geekbench for example was not ok with the 1:8 at 109 bclk, neither was x265.

That's why I switched to 1:7 for really high bclock. Had a small drop in performance but system is fully stable and you can practically just boot, fix your subtimings, and bench I believe if I had Hypers at ~1030MHz 7-8-7, my scores would be a bit better. No reason for 1:8 divider if you are going to use Hypers

Now regarding Globals, I tried so hard to go for the first place on x265 4k, mainly because the system has to be stable for 50 minutes, or 1h30m if you use overkill. It's so difficult to get 0.61 though I squeezed some runs at 109.5 bclk but again got 0.6 Same goes for XTU, it's incredibly difficult to get more than 80 marks. I tried RAMs at 6-10-6, 7-10-7, 7-11-7, 8-12-8, then dropped to 1:7 divider and tried 6-9-6 with super tight subs, always the same score, 80 marks... Must have seen 80 marks like 30 times, but still no 81 LOL.

Anyway, I only have Cinebench and wPrime left and then I'll stop torturing the G470 and move to i7 2600 (non-K model) and 2500K. I've already tried 2500K, on SS it maxes out at 54 x 100.5 but I can still get some hardware points so I'm cool with that.

Thanks a lot for the information and good luck with your benches too

I will read carefully Interesting about eh bclk skews. Familiar with P45 cpu and mch skews, but not on newer chipset, will have to dwelve into that to get higher bclk.
Ram ratio and bclk go opposite: lower ram multi = higher bclk, and lower timings, so a trade off to find.

I have done my 8.1 32 install, benching i3 4160 on XTU... will see if I can beat my previous score. On 7 64 I got stuck at the same values using cas7 instead although having a higher bclk...! hope I can take a few more xtu points


EDIT: baseline score identical between 7 6 and 8.1 32

OK confirmed. nonK Skylake scored same on old XTU 6.0 vs this new mandatory XTU 6.4.

Testing was z170 OC Formula ... 12-12-12-28 1T rams. My x3 bios saves all similar ... with slight difference on ram timings.
10x runs per 3x bios profile saves all scores " nothing below 738 XTU score" i3 6320

Then the new XTU tested same way 3x runs in each bios profile saves. Exactly same " nothing below 738 XTU score "
_______

If anything I may need slightly more V core on the latest XTU version ... as a restart can result machine switches off ... unrelated? PSU?

G470 is better but much harder (and expensive to find)
Your advise on VCCIO was excellent, thanks helped a lot to do 107+. I have not played with bclk skews. They are given form -19 .. 0 .. 19 I believe. Any tips were to start?
I also try to boot with bclk as high and close as possible than the target. so 106+, with ram almost all set to best values, and fine tuned few timings before starting.,

Sopmething else I noticed, trying to go to high bclk straight will bsod crash, but going +0.2, then bneching, then +0.2 then benching, helps to go higher. on G465, that takes a long time but eventually I could make 0.59 fps on 4K like others, and a decent 2.31 on 1080p.
Too much Vcore is useless too, actually counterproductive even, given the cpu runs at low frequency and never exceeds 40C on a small AIO 120mm.


I need to improve my scores of a G4160 now, not the best x2 cpu but fairly decent. Cpu is delidded/relidded, waiting top go on my new M7I

But I guess the most fun will be the next sempron 145 and AMD x2 -> x3, and x3 ...

I also get Switch OFF on XTU crash, which I didn't have before. No toher bench software does this.

Good to see that 6.0.x (and others) and 6.4.x bench the same scores. In my case, 7 64 = 8.1 32 in terms of score, probably but not sure yet because I minimise the services opened. will test once more on Haswells, and my latest 4790k doing 5 @ ~ 1.27 V

Older Antec Quattro. As they are multi 12V rail. Current draw? I'm uncertain ... so swapped psu for modern one.
But not same issue.

XTU would complete fine. Plenty of time ...1x minute even to save score + XTU file.
So then just do a restart of the motherboard & it would switch off completely. Volts too low on processor?
Yep I don't get it anyway ... unstable for sure.

Just doing the mandatory XTU 6.4 for now ... little point to the older ones with only 5-6 days remaining grace period.
Wish the 7350K here would stick x52 multi ... bugger!

Thanks for the thread, I was able to run xtu on my i5 3470 using the windows update.

Hello everyone. I am having a bit of an issue. I am noticing a common xtu score of 1300ish with the 6600k clocked between 4.3~4.5GHz. I have mine at 4.9GHz with RAM at 4000 MHz 16-18-18-35. I can only get at score of 1008 at the highest. I am using the ASRock Supercarrier motherboard and benching in Win7. Any help would be greatly appreciated!!

Do you have service pack 1 installed for avx?
