Hmm, what's the reason that many of you go up as high as "ultra high" as LLC? Why not go "extreme"?

Extreme is going beyond llc and raises the voltage during vdroop.

anybody knows 1155 socket mounting holes distance mm x mm ? i gonna do new holes my heatkiller 3.0

There's plenty of information on Intel's LGA1155 Socket Manual, with all kinds of drawings and specs: it'd be the safest source for that kind of answer.

75 x 75 when I looked into it.

wow went from 1253 to 1204 and now the same settings that would cut power at 50x100 on superpi1m are now stable for superpi32m

EDIT: anyone else able to boot 1.5v+ but as soon as you start a bench it cuts power?

Manual is very buggy, I had 20x Intel Burn Test Max stable overclock with 46x100 1.270V, and got BSOD just listening to Winamp and browsing, upped voltage by 0.01, still BSOD while playing Dead Space 2, finally had to up it from 1.270 to 1.290 to get it 100% stable.

Offset mode on the other hand doesn't even require long stress testing, it is stable if it passes 3DMark 05/06/Vantage, if not I just up the voltage by 0.01V. On manual I had to use 1.350V (1.320-1.336 in CPU-Z) for 4.8GHz. With offset that would be +0.075V, but it is completely stable with just +0.045V (1.296-1.328 in CPU-Z).
Agree. Honestly, offset is the way to go on SB chips. I'm using a +0.020 with a Medium LLC and the system is stable with low volts and temps.

I must be doing something wrong. I'm on the 1053 bios with ultra high LLC. When I'm pushing my 2500k into the 4.8 to 5.0 ghz range, I can achieve stability using manual voltage only. I would like to use the offset for lower idle voltage. However, when I set the offset to match the vcore I observe under load with a manual vcore setting of a a given overclock speed, the system becomes terribly unstable (bluescreens galore). I could try adding more offset voltage, but then the vcore under load becomes higher than I would need for stability with a manual vcore setting.

hi splave, no probs here with the 1253 with voltages above 1.5
I'm still on air, waiting for some ln2 to test better.
As far as I can see until now, I can boot in windows with 1.58v, but nothing changes from 1,51... so I do all the benches@1,51v

I am experiencing the same behavior with offset voltage compared to manual voltage.

Played with Offset for about 4 hours last night, in none of my situations was it better than manual. That went for 4.0, 4.2, 4.5, 4.8 and 5.0 profiles.

[Praz]

The offset voltage can get tricky. The issue is the amount of applied voltage throughout the range of idle to full load. Dial in the necessary offset to achieve full stability. Then try different levels of LLC to bring the full load voltage down. You may have to use a fairly large offset to drop down to the next lower LLC setting. Also when using offset voltages it is best to monitor VCORE with a DMM or scope instead of software.

[Sevenz]

i think the issue with offset is the vcore given on low cpu usage which is too low.
try linx on 1 thread you will see what i mean.
for example me i normaly need about 1.38v for 4.8 ghz but when i was trying offset with ultra high llc with 1.41 on max vcore i was still not stable.
then i tryed linx on 1 thread and i noticed that my vcore could go at like 1.280v for 4.8 ghz
what worked for me to have a higher mini vcore on load but not too high max vcore is medium llc with higher offset.
Now my min vcore on load is 1.320v and my max on 8 thread is 1.4v.
yes its still a bit higher than my manual vcore,but i dont use apps fully loading my cpu like linx so im rarely at 1.4 v.
hope it helps

I picked up the Deluxe board just a few days before the Intel defect was announced. Now I'm not sure whether to install the board and wait for the replacement to be released or just return it.

Is the immaturity of the Bios enough to swing toward just returning it and waiting for the new release in April?

[Splave]

just use sata6 ports or the marvell until april

[Peter949]

Just use it. Asus has a replacement program which by that time you'll get a new board with a newer rev. and bios.

Thanks for all the information!

The great thing about using OFFSET mode is that the CPU will not have a constant high voltage applied even when the PC is idling, instead, only when really in use, or maxed, the high voltage will be applied.

@ first, I wanted to disable speedstep because the PC would still use 1.35V +/- even when idling @ 1.6ghz, which seemed pointless to me.
Now, with Offset I use speedstep since I know the voltage will go up as down when needed!

[Praz]

Hard to beat offset voltage for 24/7 use when dialed in properly. A little less the 0.375V difference in the screenshots below between idle and load.

Yea but just like that, you are using way too much voltage to be stable with offset. With manual, you could probably bring that about .05 further down.

[MaStA]

I would think the voltage would vary on each individual chip. I was using manual voltage, but yesterday I messed with the offset voltage and was able to stay stable at the same load voltage I had set on manual. I haven't messed with it further to see about getting it lower yet though because I haven't had the time.

If I was running the board fully loaded 27/7 manual would be a viable option. But since the majority of the time it is somewhere less then 100% loaded offset is a better option for me. For anyone that wants the CPU to be at loaded voltage when at 1600MHz the setting is in the BIOS to make it so.

You right. Set to manual the needed loaded voltage is not much different then what I show in the screenshot. Where the voltage really gets kicked up is if the configuration requires additional offset to stabilize from idle to a near loaded state. But that can be fixed somewhat with LLC.

[Leeghoofd]

Very nice to hear that Praz... asked Super Peter and Jack for that setting... glad it will be there in the new upcoming biosses.


@offtopic : Still got issues with the Sabretooth : cold boot issue, not resuming from S3, USB overvoltage error (with 1204 bios and only USB mouse connected), not being able to lower PCH voltage (stuck at 1.05)...

Which setting? Offset on the M4E? It should be there on the BIOS you are using.

[Darkstormz]

Got a strange problem here. When i put my Zotac GTX 480 in PCIe_x16_1 I get full x16 2.0 speed but as soon as I stress the gpu the system will freeze.
When i moved it to PCIe_x16_2 i got x8 2.0 speed, and the card works 100% fine when I put some stress on it...

Everything at stock, any suggestions?

Praz can you give as some bios offset settings for X48,X49 or higher ? ,i like to give that a try
thanks
