You referring to me or Grinchy? If you're referring to Grinchy there's no need to drop back into derisive statements, and if you are referring to my post, you obviously haven't read the thread, or cannot understand my post. Either way, some things are best kept to yourself ;)Quote:

Sorry for any offence.:)
More thought needed next time (by me :up:)
So as long as my cpuz reads 4.5ghz, I get in? It doesn't matter if my computer is detuned to the point that it performs like a 3.2ghz machine, but passes 20 loops of linx?Quote:

All this was, and is, for fun and only for fun.
If you have any grievances perhaps you should direct them to "Zalbard".

Read the 1st post. You must have Linx runing the 21st run when you take the screenshot.
Your gflops are low as sh*t even for non AVX windows.

It is better to turn HT off and then run 4c4t and 4t in LinX (for improved Gflops). :confused::)
Thanx

Desclaimer: I had to bump the volts from 1.420v to 1.44v ( in bios ) in order to run HT on without freezes/BSOD. 1.420v freezed after few seconds, 1.435 BSOD after the 2nd run. Also keep in mind that I'vent yet been working in to optimizations for HT on voltages, so what did was just work the vCore out until I got it stable, more can be done to bring vCore to around 1.435 at least, I'm sure.
well i got 4.5+ghz to start being stable. been working on 4.65ghz with full mem and 2x uncore with a 980x. i can get it to pass everything upto 8gigs of mem out of 12 and it's averaging around 101-105gFlops.
i'll post 4.5 here in a bit, but i'd rather show 4.65 with 100+gFlops :P
alright, here's my offering.
Cooling - Water
CPU - 980x BATCH: 3013A540
Motherboard - Rampage III Extreme
4.509ghz cpu / 3733 uncore (155x29)

1.709v DRAM / 1.815v PLL
6gb (4096 out of 4133 available) 1866 CL9 stock timings
hyperthread OFF
haven't been able to get 12 gigs to be stable yet still. i get through about 10 rounds and then it errors out. pretty sure it's wanting more VTT but i refuse to feed more than 1.41v to it.
don't mind the temps on GT. actual temps are between 83-84*c, GT's just reading off of bad internal sensors. i've checked a million times through bios, ROG and about a dozen thermal sensors i've swaped over the top of the cpu.

try increasing your uncore there Crossg, that'll boost your gFlops. if you can get it upto 2x you should be nearing 110gFlops at that speed and your temps look decent enough to try it.

Thanks mate, yeah seems like I got lucky. Had to look through a lot of results on the web with unconfirmed stability, just 'high MHz CPUZ only' shots and vantage runs and get a batch list together. Had 3 batches locally to choose from and went for what I thought would be the best one.
Very nice CPU! It looks like you can run it LinX stable at 4.8Ghz at least with Vcore less than 1.4!Quote:

assuming you're still running 12gb on that rig as shown in your sig. for me it's taking about 1.418 - 1.425v-ish VTT for stability with 2x uncore and data link around 7.4-ish i think (can't recall off the top of my head, away from home at the moment). as long as you can efficiently take the heat with no higher than about 85*c average temps between all 6 cores you should be fine at that high of VTT. also know 980x chips have crapy sensors from what i've been able to find so the high temps you're seeing on only a couple cores is directly related to these crapy sensors apparently. for mine i've had cores 1 and 5 on my RT-gt touch 98-99 yet PC probe, bios, rog and HWmonitor all show about 82-85*c on cpu temps.
Just tried the same settings on my 990X and bumped the uncore to double the ram speed and set the VTT a little higher to 1.3375. No desire to push the Vtt any higher as I don't think the gflops will increase and it does pass LinX. I don't run this 24/7 just test and bench. I use 12 Gb of ram in day to day use but when benching I use 6Gb. Less heat. My ram isn't the greatest for Ocing so this was just to see if i could get 100 gflops and were drifting off topic here.:)Quote:

A question here or there I think is fine, but I just hope this thread stays specific and on task rather than drifting. Most threads like this get forgotten about and never updated, Zalbard does an awesome job and I think it's the spirit of this thread to stay specific about 4.5+/20+ loops.
EDIT - I dunno, reading over my post I seem like some whinging old guy. Im all for helping each other out and stuff, just, I dunno it sounded ok in my head.. :shrug:

Getting over 90GFlops is dead easy if you are running with HT off zoson, as you have found out. But try running the same clock with HT on, you will then find a completely different result.Quote:

Were there any voltages and/or settings that were key in improving the Gflops for your processor? I start to loose performance in this respect right after 205bclk or it is intermittent and I have to try restarting LinX several times. I've messed with CPU PLL, IOH, vtt, memory timings and subtimings, round trip latency, DRAM ref volts, CPU/IOH clock skew, CPU diff amplitude and can't get consistant performance. I've also disabled a ton of windows services like superfetch to eliminate any program in the background.Quote:

I think LinX isn't the best way to test your RAM, though, but you know that. Looks good nonetheless! :up:

Now that things are back on track and I have some free time I will think about updating the thread's formatting. Should look a lot nicer. Should be also able to get the results in within 1-2days, too. I actually keep thinking I need some software for simplified result input, lol.
Hi Zalbard,
Thanks for keeping up the thread. It's a really nice way to organize the community of extreme overclockers.
Might I suggest for the thread update that you sort by GFlops, rather than speed? It would simplify the maintenance of the thread by making it possible to remove the different sections for specific CPU's. It would also express the ranking as a performance level, rather than just a benchmark. The speed milestone would still be the barrier to entry, but competition would be based on performance!
It would also make it very easy to see the clock per clock comparisons between old and new generation cpu's. 'oh hey at 100Gflops, xx cpu is lower clockspeed'. The community could zero in on those people who know tricks that boost performance(to get their insight) without having to sort through every result to find who is actually performing well, vs who is just running at a high clock.
Thanks again!
Very nice chip! Would like to see what it can do with proper AVX LinX installed :up:Quote:

yup my 2500k at 4.8 maxes around 139.xx with SP1 installed, quite a difference from beforeQuote:

Hi, and thanks. :)Quote:

Another issue is memory performance. Linpack seems to be quite sensitive to that. It doesn't really translate into real-world advantage, though. For example, a 4GHz CPU with 2GHz RAM may be faster in LinX than a 4.5GHz CPU with 1GHz RAM, but it will be the other way around in pretty much all of the applications.
Not to mention that produced GFlops are often inconsistent.
I think it makes sense the way it is now. LinX is used to measure stability, not performance.
However, it's up to the members to decide. If I see many more people supporting your motion, I can rearrange everything.
I am going to have to pass as using gflops as a metric and as you were saying the numbers are inconsistent, and what really does matter is real world applications, I feel the current methodology is inline:up:Quote:

I also take issue to the memory remarks... I've tested all the way from 1333 cas5 to 2200 cas10. The difference in gflops when cpu speed is kept the same is very small, as long as the memory size/problem set size is consistent. 1-1.5Gflops tops.
Also, if you don't use enough memory, you cannot stress the cpu correctly! The problem set will not be large enough to engage all the execution units of the processor!!! That is why there is lower Gflops with lower memory. The stress test is not complete. It is also why we see lower temps with lower memory sizes, and also why we see lower temps if HT is on and memory size is > 9gb... It is not difficult at all!!! I can complete linx 21 loops at 4.9ghz with 512mb memory size! Gflops is less, but it completes! Is that stable? no!!!!
In summary, I think the reason for inconsistent gflops is they are doing it wrong!!!!!

well at the end of the day this is zalbard's rodeo so we will see what he wants to do, but I like having the list sorted by raw clockspeed:shrug:
IMHO this thread is about running at a certain clock speed while verifying stability with Linpack. If you really want a performance comparison of FLOP performance throughput it might be a good idea to start a new thread with it's own rules to achieve that. You'll have to decide what you want, max FLOPS overall, FLOPS per core, FLOPS per GHz or maybe even FLOPS per watt for efficiency (may be hard to achieve) etc. Perhaps also some distinction between FPU, SSE, AVX. :shrug:Quote:

I have an SS that I hope to get running soon and this thread gives me the ideal MHz targets to try to aim for without taking me to areas of o/c'ing that require too deep a knowledge of the wherewithal that a casual ocker like myself wont bother with. When I have problems with my setup I know there are plenty of knowledgeable ppl in this thread to answer my (hopefully) not too difficult questions, thus allowing me to enjoy the thread for what it is................
a challenging bit of fun :up:
OOPS! I hope my recently posted "challenging bit of fun" gets in Mr Zalbard :worship:.
Hi everybody!
A little bit old-fashioned, I know, but here is my application to the 4.5+ GHz club:
http://img859.imageshack.us/img859/9...214500136v.png
(Linx 20+ 64-bit maximum, E8500, 4503mhz, 1.36v, Gigabyte P35-DS4, Thermaltake Big Typhoon aircooling, 15 degrees Celsius ambient, OS Win7 SP1 64-bit in diagnostic mode)
The run finished successfully, in fact (all 25 iterations), and shortly after that I reran the test (also with success), just to make sure everything is OK; don"t want to waste space for the pictures, but they are available on demand.
(Gigabyte boards are Linx- and IBT-friendly, I guess.)
