Do you call that an increase, 0.010 ? I give up... no idea why you run LLC off... just leave it on AUTO... try upping VCCIO to 1.15. The dimms are 100% okay ?

Because LLC is evil. It adds the unnecessary voltage on top of it. I've seen some crazy spikes with medium LLC, and turned that off since then.

I've no idea why should I increase the voltage if using manual mode I need V1.33 for 45x, but V1.35 isn't prime blend stable with offset. This basically concludes that the offset mode isn't working correctly as also the LLC.

[Sauron_Vie]

BSOD 124 means mostly "add/remove vcore or QPI/VTT voltage", and if ur sys errors on prime with that voltage than it´s not stable. It´s also not healthy for ur cpu to set llc off but pumping then more and more vcore into to geht it stable find the sweet spot between these settings my rig is passing prime for hours and and linx by 4,6ghz with a offset of 0,02 and a regular llc and no pll overvolting, so i think u should test a little more.

Well, I thought LLC on regular means it's off, isn't it?

I've been testing for days though and I keep doing that LOL. Bumped the RAM voltage to 1.55. Will see what happens.

[Sauron_Vie]

Regular means 0% more, but take a quick look for this short explanation: http://www.xtremesystems.org/forums/...&postcount=506

If I would run my ram at up to 1.75v, is there anything like the vtt-vddr correlation on s1366 I need to watch out for?

Just to clear things up I'd like to reuse old 1.65v DDR3 2000 9-9-9-27 Ripjaws that do react quite nice to a bit more vddr. (also they run good at 1.35 but that I won't run with sandy

I've seen that issue 5 times today, but it's because I'm pushing my Cpu and Gpu's to their limits and 3DMK 11 really stresses the card more than the cpu. Happens on my 980X rig as well so it's probably vid card related. Right now I'm using beta 270.51 drivers but any driver so far has done the same when pushed.

How are you keeping your temps so low? I'm running a custom water loop and at 1.36vcore it hits 73C. I've reseated the block 3 times and no difference. I have my setup at 4.7GHz with everything set at AUTO except for manual vcore and dimm. I found LLC is a must unless you want a 1.55vcore. I had set mine at HIGH until I found I needed almost 1.38v to run Prime95, but I currently have it set at Ultra High and running at 1.36v but like I said the temps are too high at 73C. I'm thinking of going to LLC = Extreme and dropping vcore to 1.35 or maybe 1.345 to get th temps down.

[PJD]

Besides, if Intel says not to go over 1.35v, who am I to argue?:-)

In fact I believe Intel never mentioned anything but the maximum voltage the new SVID encoding can express (1.52V, which is definitely not safe for daily usage).

The vtt vs. vddr correlation on 1366 is actually a myth. I've run well out of "spec" before, and I believe intel actually acknowledged the myth. With that said, I'm not sure if anything like it exists on SB.



To keep this post on topic, I will be getting a 2600k and P8P67 Deluxe in the mail next week. I'll post back with my results, or if I have any questions.

That was a quick bench and if I tried to run prime at that voltage it would overtemp within the first minute. Mine would probably be around or over your temps with 1.35 volts.

P8p67 Deluxe 1503 bios

[newls1]

Can someone PLEASE post a download link to the B3 P67 Sabertooth 1502 BIOS!! I cant find it anywhere, and this 1305 BIOS is horrible

[Leeghoofd]

In what sense is the Sabretooth 1302 horrible ? 1305 works pretty okayish here...

The vtt vs. vddr correlation on 1366 is actually a myth.

You sure about that ?

What happens with 1305, i have it and runs perfectly...

Well then maybe you're lucky but I didn't hear that Intel ever retracted the statement that VTT must be within .5 of vDDR. Thanks anyway. I'll wait for a few more comments on that topic.

You sure about that ?

Maybe didn't visit the graveyard...

Anyhow. So there are no such correlations on s1155, would that be correct?!

[Darkstormz]

I got this strange issue going on. If I run AS SSD Benchmark with Windows Aero on, I will get an error saying "nvlddmkm.sys stopped responding and has recovered".
If I disable Windows Aero the benchmark will run without any problems.
I get these issues whenever I run Crysis 2 also. Tried everything including format, drivercleaner, you name it...

System is @ stock clocks. Running Win7 Ultimate x64 SP1

Ok, getting a bit more idea of how SB overclocks. I've been trying to get 4.7GHz stable at 1.35v vcore. The best I was able to do this was set vcore at 1.40v vcore and LLC at HIGH, because the vdroop was too low and would lead to BSOD 124 error codes. But one thing I could do is set LLC to Extreme and then drop the vcore to 1.35v. Now there are a few here that see huge voltage spikes but the highest I saw was 1.368v. Prime 95 ran for 2 hours.

I didn't like the temps hitting 74C, so I tried to drop to 4.6GHz using 1.35v vcore and LLC = HIGH. Nope, still BSOD 124 error codes. I noticed that vcore would drop sometimes below 1.3v, so I'm thinking maybe the way to keep vcore stable and lower is to use a higher LLC. Is there anything that can record the max VID like RealTemp does with temps? Unless I sit there and stare at the vid on CPUID, I'll never really know what the highest spike is and that was less than .02 of the vcore.

You might want to try offset voltage at medium or high LLC instead. Lots off people have had success. I use it for my 4.7 settings. It supplies about 1.32 vcore and drops to 1.312 under load. Strange but it works.

i am using also offset 0,02 and a little bump at the add turbo vid for 4,6ghz. for 4,8ghz i need 0,03 V@offset and a little bump at the add turbo vid

[PJD]

Ok I understand the offsets, but what do you mean bump of the turbo vid? You mean vcore? So, if I'm looking good at 1.345vcore with LLC = Extreme although at a peak 74C on the 2nd core, what would I need if using offsets?

[Sauron_Vie]

u can add additional turbo voltage within the efi menu "CPU Power management". but be careful with this setting

I replied to the Myth claim too... there's a correlation on 1366... not only for reliability but also for stability...

1155 we are running the Gskill Flares for along time now at 1.7-1.72VDimm and IO at 1.175, nothing has happened or gone down yet...

Niiice, that mighty fine and exact the news I wanted to hear.

We'll see what those oldy Ripjaws will be capable of. Thanks man.

[PJD]

Ok, had some time at lunch to play with offsets. You all must have some nice procs because even at 0.07 offset and 0.04 add turbo volts, I didn't even get 5 minutes of Prime95. I started off with 0.02 and 0.01 and at first I couldn't even get to the welcome screen. Then I added a bit got in Windows, then crashed in Super Pi. Eventually, I got through Super Pi at 0.05 and 0.03 but immediate 124 BSOD running Prime 95. Add some more offset and add turbo volt and I got farther. I see 1.32vcore before it hangs. I'm thinking I'll end up needing 1.10 offset and 0.07 add turbo volt before I'm done. What do you think? Do you turn any of VRM settings on or leave everything at default?

[Sauron_Vie]

try for 4,6ghz offset 0,02 and about 0,15 v turbo vid.
