Intel 4.5GHz & 5GHz LinX Stable Club

[dejanh]

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

You misunderstood obviously. What i ment is that he will get better info from the R2E dedicated thread rather than this one

[RoEy]

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.

Thanks again,

RoEy

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.

Thanks for the submissions, guys! Great job!
Updated.

On air, good job!

Nice temps! What cooling do you use? And what can you say about OCing Gulfy so far?

Welcome, guys!

thats gr88 i needed around 1.49v to reach 4.6Ghz with my A0 i7 980x...

This is really good i am very impressed, a very nice chip you have there. I still did not get any retail i7 980x or a Xeon

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 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

I noticed some submissions with "HT off" so I had a go myself. I know the memory is slow and the griddle flaps low but, hey.............


I'm using different memory from my sig

[PiLsY]

Newhit whats your batch mate? Almost exactly the same clocks as me at samne volts - my bclk tops out at 203 for long term high load stability though.

I have updated your score.
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!

[newhit]

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.

[SteveRo]

Good morning,

Had this i7-980 for about 12 hours now.
My first 980 submit to you.
I think I can go higher.
Cooled via chilled water - 2x boreas in series to an apogee xt block, mcp pump with xspc top.
Pcie at 115 - can this cause low gflops?

[=[PULSAR]=]

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

Cheers, I will try that when I get back home

Sorry didn't read that bit.................

My bclk doesn't like to go high either, 204-205.

[zalbard]

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.



Thanx to "Pilsy" for reminding this old head how to get the startup correct. I also had a rethink about my bios settings.

[Sniper]

DDC, HK 3.0, PA120.3 + another 360, 21 ambient/air intake temp.

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.

[CryptiK]

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

[Sniper]

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