Angelreaper can you make me a favour and try to run linx with problem size set at 25000? I want to check if it makes any difference at the vcore required to be stable. Nice job and great cpu you have there :up:

Sorry but 11500 problem size is very low to stress cpu. Try again with at least 25000 and post back.

From what I heard you claimed it to be 4,6ghz HT ON stable?
That's first point. Second point is, without using at least 4096MB of used ram don't even try, otherwise it's too easy. 7 minutes of testing is nothing, but :banana::banana::banana::banana:.
Try one hour, it will crash :) Don't blame us, you were the one claiming 4,6Ghz ht on stable on air.

Sure. But also sure about that it won't be so called "4,6GHz HT ON". Because that is the case.

yes, water cooled.
water chiller, i think...i cant remember. and like a dummy, i forgot to put a side note.

i never claimes i was stable 4.6 ht on ;) learn to read
cpu can prime like its nothin so go find yourself an i7 that will do 4.5 with ht on and try for yourself
maybe 1 day you will:rofl::rofl:
dont hate cause your i7 suks

Learn to not brag on the forums before you actually did something.
I never tried to have 4,5HT ON, and like I said before: 4,6 HT ON ON AIR is almost impossible. And you were the one claiming you've got that cpu capable of doing it. You failed m8, since I can't see 4600mhz ht on in the pictures.

Actually you don't want me to upload screenshots of an i7 doing 4,8GHz HT ON linx stable that my friend was running on SS. So better don't say "maybe 1 day you will". Instead of that upload your 4,6ghz ht on mr. fail.

i never stated i used ht
that was first time i even completed passes linx on ht
so dont start puttin words in my mouth and drop the crackpipe

and if i wanted to do 4.6 with ht i can all i need is proper coolin cause i know the cpu can do it

maybe i should ask god to gimme his linx pass @ 6.0 :rofl:

Very low, that is what I was thinking.

Started it up, been Folding ExtraLarge WU's for a few days so shouldn't have any issues passing LinX. I'll post when it finishes (if I remember to do it today :p:)

Apologies, but I wouldn't know what a high value is or what the problem is or if there is one. I just pressed the required buttons and waited. If there is another test required just let me know.
:up:

These are my settings. Maybe the answer is there (low bclk?, QPI?)

GFlops is very sensitive to memory timings. That looks about right for 8-9-8 or slower @ 1600mhz (or maybe 11/12 @ 2000mhz). I'm guessing you have some auto memory timings :). Check the memory tab on cpuz (or download cpu tweaker for more detailed readings) to see what your timings are at. Linx is much like SuperPi in terms of tweaking memory - higher memory performance can overcome cpu speed in terms of GFlops.

Can we post i3's here? I only ask as its a bit easy to get 4.5ghz on them - wonder if we need a 5ghz club for 32nm? Seen a fair few 6xx series at 5ghz even on air. A good 5xx series seems to top out at about 4.7-4.8ghz. Mine struggles past 4.5 and needs loads of voltage - guess that makes it about average?

Any chance we can get the i7 list divided into 'HT on' and 'HT off' groups, since there is a significant difference in the difficulty of one vs the other?

Here's my submission.

I don't think there is much point, is there? Would be splitting the list in waaay too many small parts... I'd have to do the same for Gulftown, i3, etc...
I could also add whether HT is on or off to each submission (in bold) as an option.
What do you guys think? Shall I bother doing either?

I didn't mean physically divide the list, just noting whether HT was on or off would be fine. I just think it's relevant since it's harder to have HT on. Thanks for your efforts with this club so far :up:

Sorry to post here in this prestigious thread without screen shots but I’m just curious if people in here have LLC enabled or disabled?

I’m currently at 4ghz, 920 d0, R2E,6gb 3x2 Corsair Dominator 1600.

Bios:
Vcore – 1.275 (1.31 load)
VTT – 1.275
LLC - enabled

Got custom water cooling with a Heatkiller copper (nickel-plated), tfc quad rad and 4870x2 in loop.

Temps at 4ghz under Linx, 67 66 66 62

I just want to know whether it’s better with LLC on or off

How far can I safely push the volts for 24/7? I always thought it was 1.35 for vcore but some of you go way passed that, lol!

I’d love to join this club!

Thanks,

RoEy

Certainly not the right thread to ask something like this. Better try at R2E thread. But your temps seems a little high for 4Ghz with 1.3v.

Hm, in fact, I don't mind, actually.

@ RoEy:
Pretty sure most people run with LLC enabled, but you have to test this by yourself.
Regarding the voltage... Don't be shy, up to 1.5V vCore and VTT should be fine. Just don't fry your chip with high temps.

I run without LLC, or if you will with Vdroop enabled. I actually found my clocks to be more stable with it on...don't ask me why lol

Thanks for the info guys. Apologies for asking here. I have a 4870x2 in the same loop hence the temps. Still ok from what I've seen others get anyway.

Got rid of my 860 rig...Just could not get 4.5 on it....plus the EVGA P55 SLI board was very flakey.....replaced it with 920 D0 rig....Here is my first run at 4.5...I am going to try to see if I can get a lower core voltage though...

...next up... 4.5 LinX on my 980X rig :)

All internal micro cooling with gpu on the same loop.

For daily use I go with @4.0 with HT on and all energy savings on, but going higher is just too much stress to handle for a single double rad in push.

Water. Apogee GTZ with MCR220 + MCR120 is all, I'll be using more radiator when I finish my build.

Working on higher bclk lower multi for 4.6Ghz, BIOS has some issues though. Can't set 24/25/26 multi, if I do it makes Turbo all messed up even with Turbo disabled :shrug: Also can't change uncore at all, it takes in the BIOS settings but doesn't change in Windows. Hopefully a non-BETA BIOS will be out that fixes some stuff with these newer chips.

Edit: I see F12 is up on Gigabyte's site now, I'll give that a shot in the morning when I get off work :up:

However, there is something wrong with either your run or your overclock, your GFlops value is really low. Should be nearly twice higher.
Get to tinkering! :D

Need help please

This is where my knowledge parts company with the necessary adjustments needed. I have two sets of memory...............

G.Skill F3-16000CL9T-6GBTD (DDR3 -2000 CL9-9-9-24 1.65v)
Corsair TR3X6G1600C7 (DDR3-1600-CL7-7-7-20 1.65v)

The G.Skill is on the recommended list but the Corsair isn't. I have loaded up "Cpu tweaker" and "cpu-z" and put in the values listed but get lockups unless I relax the settings to 99924 (x8.0) with "Auto" set in Vtt/IOH/CPU PLL, on either set of sticks. The best I did was with bios F3h and the Corsair set to 88824 for my original 4.6GHz run.

I have tried various combinations of Vtt/IOH/CPU PLL and obviously Vcore but nothing gets me through. I think that it's this area that's holding me back. If it's acceptable I will go to the "UD7" thread and post this up for advice.

newhit - use diagnostic mode see if that helps.

Start menu > type msconfig. Choose diagnostic mode and restart.

Set memory size to 5120 and make sure your page file is enabled.

Good morning,

Had this i7-980 for about 12 hours now.
My first 980 submit to you.
I think I can go higher.

It is usually a sign that the vcore it just a hair too low.

No, I doubt that.
Things I can think of: 1) just 4GB of memory used, it would be higher if you used 5GB, 2) Gulftown has lower L3 frequency, 3) Classified motherboards got some kind of Turbo Performance option for Gulftown, perhaps Gigabyte is yet to come up with that, 4) Linpack library could use an update for Gulftown.

Sorry to get in the way of all the "Gulphie" posts, but talking of "Girggly blops", I've redone my LinX 20 run to show that my setup is functioning correctly.

Working on a higher 20 run, but seems linx doesnt like more than 226 bclk for now.

newhit: Still think your gflops is a bit low. Usually on my setup I get low gflops if vcore is a tad low, or some other process takes up to much cpu time.

Really nice run Sniper. Temps are great too for 21*C ambient.

Thanks. Yes temps are good up too this point, going higher on vcore/mhz soon gives temps in the low 80's.

Still too low :eek:..........Not sure I can strip out any more dross :shrug:. A lot better than it was though :).

Nice run there Sniper, maybe you can put an SS on and go for LowFat's run :up:.

Well, 4.7+ ht on is not gone happen on water with my chip. But I'v had SS before, not doing that again.

LowFat's run is also with very low gflops, looks almost like throtling.

I quess it is time to go 32nm, just wish they didnt cost so much.

Your Gflops are really low i got around 6x Gflops with 4.6Ghz, i dont think the PCIe is the culprit. In any case the voltage is quite nice :clap:

Try a higher clock and see where your Gflops go even if it means i will be taken out of my no. 2 position lol

Newhit's gflops looks bang on to me for 8x me and 16x uncore... Could add another 5-8 gflops by going to 2000mhz 8-9-8 and 20x uncore.

Glad I could help dude :up:.

Yeah, I guess the different mp/bclk/timings etc can add up too the difference I see when I test linx gflops at the same speed.

I'm peaking at 66.xx Gflops on the X5677 at 4.65Ghz, more clock = less Gflops and tighter RAM/faster RAM = less Gflops :confused:

I figured LinX would be a 100% linear scale with cores and clocks, but guess not :shrug:

On my 980, if I drop Linx from using 4 to 1GB memory my gflops increases from 53.xx to 69.xx, seems like it should be decreasing not increasing?

Agreed. I'll give it a shot when I get home, no that Gflops matter all that much. I still love LinX to do a quick 10 pass test and if it passes that, I haven't had an OC fail at F@H that made 10 passes (fastest way to find a quick stable OC for me)

I find linx very sensitive to L3 cache speed. Higher uncore = much higher gflops. TRCD timing makes a big difference too.

The 980x L3 cache also has a higher latency than quad cores. Which I think is where the decrease of gflops is coming from.

That could be, the 32nm Xeons seem to be locked at 20x uncore so can't crank it up too much.

66 is too low? Just fine if you ask me...

SS yes or no

Have to ask Sniper,
You don't seem too keen on SS. I notice you talk from past experience. What is your dislike of it (I haven't been around for a while)? Also, is this "bclk mod" easy to do (I'm ok with a soldering iron)? What does it involve?:confused:
Not to try to get ahead of you of course :rolleyes:

The bclk mod is for "old" GB X58 non A mb's wich is limited to max 103 pci bus without the mod.

I'v had 2 SS back in the good old Athlon XP/P4 days, a VapoChill and a Prom. Both worked ok for a while I guess, but there where several disadvanteges for me:
- They produce more nois than my water cooling setups.
- There's allways a risk of condensation.
- Greasy sockets, cpu's and mb's.

The last one is the worst. I like to test out different cpu's and mb's all the time, and with a SS all your parts will be greasy and full of goofy stuff.

You also need to refill and tune a SS to match your cpu's power draw for max performance.

I'm not saying a SS is bad, just not for me and my use.

Ohh, and please do ;)

I can do 69.xx gflops with the 980x but it has to be with 1GB memory used.
If I go to higher memory the gflps drop to 53.xx at 4GB, odd.
The proc seems to be doing fine otherwise - pcmark vantage numbers are very good.
