Well how does your theory work in relation to offset using Speedstep and c1e ?
It sort of becomes invalid doesn't it.

I can assure you that idle and random BSOD is IMC/Memory related. NOT vcore.
Because its only common intelligence to know that you need more Voltage on load than you do whilst idling.

You are increasing something, your increasing vcore. Now whether or not its producing heat on idle is besides the point, the chip is being fed more current.

I think we've highjacked the OP's thread, lets leave it (for now) shall we tongue.gif
Again to the OP, great fantastic OC thumb.gif
I wouldnt worry the slightest about those temps....theyre perfect.

Invalid? I was talking about Offset. C1E and Speedstep has nothing to do with it., there are usually on by default. What is that you mean when you say invalid? Regardless of offset or manual, reducing the LLC will require you to increase the voltaeg to get your load voltage again, but doing so increases your idle voltage. What is it that you're not getting?

Obviously load voltage will be higher than idle voltage, but you can control that idle voltage and like I have said it is one of those that can cause idle bsods, when your idle voltage is too low and when the overclock 'kick's in the voltage cannot compensate fast enough and can cause idle/random bsods.

I haven't said anything about heat or current, you go ahead thinking that but please don't make your opinion a fact.

Please do me a favour and read this: http://www.overclock.net/t/1120291/solving-fixing-bsod-124-on-sandybridge-read-op-first

Apologies to OP for derailing thread. Denim If you want we could continue this conversation in the thread linked above.

10 hours Prime

338



then BSOD with 124 code again, this time I was not browsing when it happened, so once again I'm inclined to think that I need to raise the vcore by 1 more notch, I think that will be at 1.41? not sure till I get back into BIOS.


@Denim-187 @munaim1 No worries guys, I appreciate your input, all is good. And there is nothing wrong with some healthy debate biggrin.gif And thankyou for the links.


@Snowmen @ robbo2 Thankyou


@viper12005 I agree, after previous overclocking excursions on two other motherboards, with different cpu's, I had come to a similar conclusion. This is why I purchased a solid mb this time around - you may be able to oc on a cheap mb, but if you want results a quality motherboard is a major factor and will allow to achieve the best possible results with the components you have.

@Aesir yeah I'm not sure, if I was idle when the crash happened, then I would be inclined to think that way, but I am not so sure as it happened again today after 10 hours Prime at full load.

If it would be stable at 1.41, you do not want to be just 0.01V away from unstability. Give it 1.43V.

Ok, so I ran another Prime Blend overnight with vcore at 1.41 and no BSOD wheee.gif

Also did a few passes with the Intel Burn Test to check for maximum heat.

5 ghz goodness. and it's stable. i want one! *drools*

I am not 0.01v away from instability, it was running BF3 for extended periods with no problems, it only failed on 2 instances - both 8+ hours into Prime tests.

Based on this I knew it was only a touch away from being 'officially' stable.

i agree on this. youd always want the lowest most efficient and stable vcore you can possibly get.
