PrimeGrid's Leonids challenge takes place 19-24th of Nov. And yes, it crashes with the WCG 10th Birthday Challenge so here we just have to follow our heart's. I have taken the liberty to start this thread, since I have made the hard decision of doing the Leonid thing. Basically I have no particular reason to do either this or that, I just decided. This Leonid challenge is a part of a Challenge series, which EVGA has participated in over the year. Here are our standings so far this year teamwise, and here are our user standings. The WU's are 321 Prime Search (LLR)I ran a batch of them just now to have a look, and they are considered as medium long wu's with a 10% credit bonus. One WU takes prox 33-35hrs on a i7-3970X @3,5Ghz (Stock) and it return 3300-3500 credits. Before downloading, remember to fill in the preferences correct so you don't accidently download a bunch of unwanted wu's. This is the only box you check in your pref's: And your settings should look like this: For those who might want to try this one out, remember, WU's downloaded outside the time of the challenge is not valid challengewise. Also, WU's must be uploaded before the time is out. The beauty of this is that PG credit the WU's immediately after upload, and it will be validated later. So if a wu is faulty, the credit will be substracted at a later time. Good luck everyone

Mr. Orange, I recommend you turn off Hyper-Threading in the BIOS before the challenge. Your time will improve dramatically. I'm running tests now and I'll post back. I don't think this would bee a good challenge for the 4P guys. Edit/Update On my 2500k that doesn't support Hyper-Threading looks to finish in the 15 hour range. On the 2600k, with Hyper-Treading disabled, similar or better. I may consider running 3/4 threads during the challenge but I've never been happier with my OC's so............

Yup, medium to long range wu's seem to perform slightly better With HT off. Also they are said to produce a little less heat. Besides, since this is a short time Challenge, faster batches will most likely benefit a higher amount of total done wu's. Since I mostly work With i7's I'll switch to HT/off for this one. devlin85 I'll be throwing a few cores at this one (at least)
Heh, according to Your stats, you are a card core PG cruncher. Good to have you in this one. Btw.. Nice Catch on the dashcam, I use this one one myself.

Yup, it's time to upgrade those bronze badges to something nicer . That's a cool cam, by the description I am assuming it's motion jpeg for the rear cam and h.264 for the front one? Mine is too.. I can't find a dual h.264.. I got one of those bar style ones with a corded rear cam.. but got it half off (so same price as yours) because they sent me generic one..

Mr Orange is right about that hyper threading thing.. on my i7-4820k it went from running 8 tasks at 1.5 days to 4 tasks at 12-13 hours. So this is definitely one of those times to disable hyper-threading!

So to start of with HT on start time was 35 hours and after about 3 hours it dropped to 13 hours. I stopped the Tasks restart my PC and Disabled HT and started back Run time was 4 Hours with 13 Hours Left. Do the Tasks have to Start Without HT to start with to see 12-13 Hours. i7-3970X CPU is OC to 4312MHz Running 6 Tasks and NO GPU TASKS. No real change on this rig. Update after about 50% i7-3930K CPU is OC to 4200MHz Running 4 Tasks and 2 GPU Folding Tasks. HT is Off. Still show a start time of 32+ Hours. Will snap a new image after about 42 minutes. On Both Rigs Temps are down by 5C when HT is not Enabled in the Bios.

I'm running non oc'd i7-4820k @ 3.7 (3.9 w/boost/turbo), hyper-threading off, maybe it just don't like overclocking. My last 4 all finished at 13.5 hours. They are only getting 85-90% cpu access due to GPU activity.

I wonder, but that is why we or I am testing for the most part. I do turn off HT on PRIMGRID on long 48+ hour tasks and if less than 24 I leave HT on to run more tasks and use the GPUs. I will run the next set with no CPU Overclocking and I will turn EIST back on. devlin85 Is your Bios set to Auto for vCore or are you setting it?

all the voltage settings are auto, i have set it manually in the past but never get long term stable results. I have DDR2133 memory but it's running at 1833, otherwise I have to step down the multiplier settings so it's not overclocked. I might try OC and some settings changes after this next set finishes.

Having run 100's of 1000's of prime tests through BOINC and stand alone LLR I can say without question it is best to leave HT off. Also if you overclock it should be kept to a minimal.

So even best not to Overclock the CPU or Memory? I Do know about HT. Thanks

Correct .... what will happen is the program will throw out a false positive (saying it is prime when it is not) or false negative (not prime when it is prime) without any error messages. It will not get caught until someone else runs the double check. /edit - One more thing, Intel cpu's out perform AMD's by 15% to 20%.

What Incognito II says! PG llr will stress your cpu like no other project we run. I have never had a problem at stock or even +10% but after that, failure is quite possible. Having said that, I am currently extremely confident in one my 2600k's @ 4.4Ghz. I've run 2 full sets without problems. The 2500k @ 4.2Ghz, not so much. On my test runs above the 2500k restarted after 60% complete, just after midnight when I was asleep. I found it in the morning so I lost 6 hours. My solution was to drop it to running 3 threads and everything ran fine. I've since set the voltage to offset +.020 and we'll see if that works. If that has problems I'll just run 3 of 4 threads. My other 2600k runs great @ 4.0Ghz and I'll take that. It's been stated in the challenge forums (in previous llr challenges) that fast ram really makes a difference.

You don't have to tell me that, I would say 20% to 30% form what my 4P and 2P have shown me. Thanks

If you have thoroughly tested your OC it will be okay, I run my 3930k at 4.4GHz (not it's max though). PG is definitely a stressful project. On longer units like these I don't run my 4p 'cause it's sloooww. Intel cpus for this one.

Ah, ya beat me to the memory settings yodap! I just finished running through a couple LLR's after upping my memory from 1600-2133 in my i7-4820k (It was supposed to be at 1833 but eh, must've reset without me knowing) Anyway, set it to 2133Mhz and let it naturally raise the cpu speed to 3.9Ghz, left it alone. Voltage Auto, XMP Memory settings, no HT. Easy stuff. Knocked it down from 13.5 hours to less than 12.5 and that's at 90-93% CPU usage. My last 2 results were even better! Got an 11 hours 38 minutes! 96% cpu usage.

Nice devlin! How many threads of llr were you running? I picked up some 2133 just before the last challenge but could not get to run at that speed in the p67 board it was purchased for, despite the specs saying it would. I just swapped it into a z77 board and it's purring away full speed.

I'm running 4 on that. Wish it could get full access but the GPU's needs a little. You can see it would complete at 11.25 hours with 100% usage. So I went from 8 threads running at almost 1.5 days to 4 threads running at 11½ hours! Win Win Win!! Gonna try varying OC settings, right now it's just naturally boosted to 3.9Ghz from the memory running at 2133. (Block freq @100, memory set to 2133)

Since we talk about CPU's, memory speed and mobo's. I just got my little "speedkit" on my door. One must feed the upgrade bug right? My goal was to have this ready to go till the challenge, but I might struggle to get it rollin' in time. Anyways, here is the stuff: Intel i7-5960XASUS X99-DELUXECorsair Vengeance DDR4 2666Mhz 16Gb x2 I'll see if I find time to put it in, I'm really curious about how this performs with the WU's we are about to work with. I might scream for help via my laptop later

Damn Orange! Bring the Power! Nice picks all around!! and a 10GB/s Sata Express port, nice! Bet that would boot up fast On another note, doing more testing with OC settings,went to manual settings except for voltage, I think the trick is overclocking with no adjustment of the block freq (keeping it at 100Mhz), everytime the block freq was messed with my times went up, so I'm only using cpu core multipliers. Got my i7-4820k running at 4.2Ghz with the ddr @ 2133 and it's set to finish a batch in couple hours and will finish in the 10½ hour range! Air cooled running at 82C. Little warm for my liking but they can take much more anyway.

Wow thanks yodap, your offer of help is most appreciated Opolis Nice upgrade! In the name of science!
Thx Opolis. Exactly, my sacrifice is solely in the name of science (ehem....) devlin85 Damn Orange! Bring the Power! Nice picks all around!! and a 10GB/s Sata Express port, nice! Bet that would boot up fast
Da powah has been brought Had some second thoughts about begin to fiddle with this now, this close to the challenge, but all went swell. However, any OC'ing will have to wait. Have some bad experience with BSOD's and shutdowns before, so I'm more at ease with stock settings now, especially with those wu's we are about to grind.Edit.... Bleh.. could not help myself. Enabled XMP, the CPU is now upped to 3,5Ghz (Stock 3Ghz) Downed a batch of Asteroids, see how behaves before the Leonids. (Sorry WCG Guy's, this particular PC is not able to add WCG project, or I would of coarse ran those) As you know, the 5960X is a "Octo-Core". With HT/ On, the task manager looks like this: Nice yes? The build itself isn't too spectacular, but I hope it will deliver: Sorry for the crappy pic, but it was the best my phone could do, but atleast "Our Logo" on the GPU is visible. The DIMM's are darn tight, hope I won't have any temp issues here. The case is an Corsair Obsidian Big Tower, and it's a joy to work with, plenty of room to whatever and then some. Will take a look at some OC stuff after the Leonid. Now, turning HT/ Off, and wait some hours, then we'll se what it got.
