There's a 5ghz Sandy beating him by >10GFlops at a lower clockspeed. Something isn't right with that submission. Maybe outdated linpack binaries.

I thought that as well when I posted it but there was not much 3770k 4c8t 5Ghz benches to compare with. I did look at the 2600k 4c8t benches from page 1 (see comments below) and p3gaz's 3770k 4c4t result (I get similar results when I do the same).
Yes, it does get better GFlops with HT Off. I mimicked the settings from p3gaz's 3770k 5Ghz 4t4c results and got very similar gflops (stopped at 3 iterations as the official 21-iteration submission is the one above):
Seems I'm on par at least with 4c4t 5Ghz.
I used the latest linx(0.64)_10.3.10.017 binaries. deachus' 135GFlops peak for 2600K 4c8t 5ghz result is something special, beating the other 2600k 4c8t results on page 1, even those with 5.1-5.3Ghz. It also beat by 20GFlops Dumo's 5.004Ghz results which had close but tighter tRP timing. I took out my hypers from storage and mimicked the settings (5Ghz 2133 c7-9-7-20) from deachus on my 3770k and was able to beat Dumo's results only by a couple of GFlops:
So there's some marginal IB gain from Dumo's SB results but still lagging like everyone else when compared to deachus.
Yup (ran it slack on purpose to make it easier to get stable results). But tightening CR and subtimings there would give only marginal improvement and still won't catch deachus' results.
So let's have more 3770k >= 5Ghz 4c8t results please ...

There are several of us that don't lag behind deachus. It's because we leave C states enabled, among other technologies that make it harder to overclock. But the end result is our performance at equivalent clockspeeds is better than everyone else. For example, my 108 almost 109 GFlop run at 5GHz vs kitfit's 5.1GHz run that netted him only 110GFlops. Where the response by others was 'wait, that seems low now that I've seen zoson's runs'. =P
In short, the only thing special about deachus's run is an obvious display of actual overclocking skill.

I may be in a wrong thread, but the new LinX with most up-to-date Linpack libraries just doesn't work anymore properly for me. Could some guru help? I was trying to shoot for 4.5 GHz HT on again after a while.
I am getting VERY low gflops with my 990X and Rampage III Black Edition. If I use older libraries version LinX 0.6.4, I get what I expect, but with the newest versions, no go. Here is a screen shot to describe the problem, OS has been installed just a while ago. Removing OC does nothing or running RAM at 1333MHz. I have tried to up and lower QPI voltage and fiddle around with uncore and nb frequency.
The most upper LinX showing 84.2438 GFlops run is an older library version of LinX 0.6.4. Run with max memory (12GB).
The middle LinX showing 56.2561 Gflops is the newest library LinX 0.6.4. Run with max memory (12GB). Very low GFlops. Lower temps reported by RealTemp GT.
The third LinX showing 82.3844 GFlops run is the newest linrary LinX 0.6.4. Run by usin 4096 MB only. GFlops are on the right track again.
Anyone else seen the same? Prime95 27.7 produces the same temps as older LinX.
My OC tested here is stable for 4 hours older LinX, 8 hours Prime95 27.7 and 8 hours Memtest86 without errors.

You must look at the Linx window downstair in the status Line. Here You see, that high GFlops show 4 Threads (even CPU-Z show HT is on) and lower GFlops show 8 Threads.

There is nothing special about my 5Ghz LinX 2600K run other than alot of tweaking which took alot of time. I still have that setup minus that CPU, have another 2600k in that rig batch# 3122C601.

Near 135Gflops peak with HT? Didn't see much of those in the list on page 1. I didn't scan the whole thread though so maybe there were HT results that didn't lag 135Gflops not yet listed on Page 1?
I don't disagree there but I still think it's special because few (none?) of the list on page 1 even came close with HT on. Those other SB 4c8t results and the single IB 4c8t submission (which was on par or better than most of those other submissions) were all "woefully low" in comparison. It may turn out to be low with respect to future IB with HT submissions but I wouldn't mind that at all.It's because we leave C states enabled, among other technologies that make it harder to overclock. But the end result is our performance at equivalent clockspeeds is better than everyone else. For example, my 108 almost 109 GFlop run at 5GHz vs kitfit's 5.1GHz run that netted him only 110GFlops.

Yes, that's what's special about it (and the other HT submissions not coming close).
edit: corrected mistyped 4c4t to 4c8t.

Zalbard hasn't updated the front page for many, many pages of results. He's been too busy, which is totally understandable.
I started a discussion in this thread about optimizing GFlops in LinX for the highest performance results. We ended up with a ton of really impressive GFlop/MHz ratios.

Ok, I got 144 GFlops on Ivy with 5Ghz 4c8T HT on in bios but not due to any special oc or tweaking skills:
Yup, it's by forcing Linx to run linpack with 4 threads even though the setting is hyper-threaded in bios. Which means it's really running with HT off despite the bios setting (and it's pretty much the same Gflops +/- as the 4C4T result I posted earlier). Which is actually how the 135GFlops run with SB was obtained. Should have seen that earlier but was only looking at the CPU-Z screen when checking for Hyper-threading. Should have checked the Linx screen first time round. Oh well.
Incidentally, fired up my old SB again (2600K batch 3101A482) using 4GB hypers with 4T on linx, 8T on bios and got 141GFlops at 5Ghz with 2133 7-9-7-20 with full stable run:
alex_tpc | Core i7 2600K [4C 4T*] @ 5000.7MHz | 1.512 | ASUS Maximus IV Extreme | Water | 3101A482
Also tried a bunch of tweaks (C-states, page file disable, real-time prio, background prio, LSC, most devices disabled in bios, etc.) but they didn't really help much on SB/IB (that I tested). Best tweak was still tightening mems of course but diagnostic mode did help with a couple of fractional GFlops.
BTW, the IB chip was getting only around 138GFlops with the same 4GB Hypers and OS at 5Ghz 2133 7-9-7-20, 3Gflops less than SB on same settings and OS. Could it be that the linpack binaries that came with linx(0.64)_10.3.10.017 could still use additional optimizations for IB? Or is it because the IB run was also on a P67 board instead of Z77? In any case, is that 119GFlops IB run with true hyper-threading still "woefully low"?

Not really. Got it from the Linx thread here at XS and crossed check the version at the Intel site: only 10.3.11.017 was available at that time. Have since tried .019, same result. I think I might have used a leaner OS install from my raid card on the 2600k run (just noticed the desktop background was different). have dismantled that array after getting a new board -- will try to get it back again later and try it if it indeed gives better linpack throughput.
decent indeed, if I could say so myself
