As far as cool-n-quiet and EIST goes, some can run it, some can't. The ones that can't run 24/7 without a problem. I guess I'm just gifted.
Now why do you have to go and be like that? All penismeasury and stuff? The first system I put together was a 286, my first internet browser was a telnet window, and my first "online" system was a 4 node Celerity BBS running under Deskview in DOS (before windows FYI). I have probably forgotten more about IT and computers than you have ever known, so please, back off on this confrontational stuff, it's not really needed.

On top of that HT is ON, (and of course we don't throttle down even when idle) so we wonder why the chip could get stressed? (No, I am not saying HT is bad, just another potential factor)

EIST is your friend, it is NOT NOT NOT a bad thing.

There's nothing wrong with running your cpu at "full throttle" settings. A lot of OC'ers don't run their systems 24/7 so having them set to 4.2ghz/1.34Vcore (my settings) is not going to degrade the processor that much, if at all.

We're well within the Intel specs on our voltages and most of us (I think) use more than adequate cooling to compensate for the extra heat generated from the overclock. Besides, my system idles at 31c (hottest core) and doesn't get too much hotter even when gaming.

As an afterthought, if you're a tleilaxu ghola from ix, you must not be very well-liked! Last I read, the ixians hated the tleilaxu and especially gholas!

I ask so I don't have to debate with someone who built 3 systems and thinks they're an expert.

The only reason I said anything about EIST was because someone suggested to the OP, who has an unstable clock, that he turns on EIST. That's bad advice, and it needed to be pointed out.

Whether or not EIST should be used on a STABLE OC should be debated on another thread, and that's all on you so don't point any fingers at me.

And the only way you've forgotten more than I know would be all that hippie lettuce you've been smoking.

That's the thing about the internet, people say things and really don't have any clue as to what the actual truth is.

How do you know I have built only 3 systems? Where would you possibly get this information?

Dude, you do not have a clue. When you say "systems" are you talking actual production systems, or should I include testing and development too? Should I count servers AND end user, or can I split them up for you?


-TG

(on edit... let's just stop this now, I honestly cannot remember "exactly" how many systems I have built, ordered, spec'd.. it's in the dozens, ..close to a hundred would be my ballpark.)

I think my quote is pretty simple to understand. If you had only built 3 systems, I'd just ignore you.

You continue to ignore the OP's problem and how EIST applies his problem in order to have some kind of nerd knowledge battle with me. Sounds like you're the typical IT guy.

ugh..lol.. I think you're right, although you *did* kind of throw the gauntlet at my feet, it's difficult for me to resist the urge to pick it up...

back on topic: iirc the "quick and dirty" OC in the guide has settings that disable EIST, and yes it does get you to 4GHz, but it's not the kind of OC I would run 24/7. It was more of a commentary on how a lot of people seem to blindly follow the guide, adding in every suggested setting and tweak regardless if it actually is needed, or is applicable to them. If the overall concern is "degradation" then disabling EIST would most certainly be a contributing factor, if not THE contrinuting factor since we know his CPU has been running full-bore since he started overclocking.

If the issue is in fact degradation, then the fact that the CPU never "rests" or throttles down even when idle is relevant to the discussion. Enabling EIST should, in theory, extend the life of any CPU.

As I've said, relax mem timings (I see you did that and also the other things), try IBT again, at your previous stable Voltages/clock frequency. Run memtest for Windows, four sessions. Each session/windows with 2750MB RAM. See if they can run error free at least one round.

Bios settings (same EXACT settings as when things were stable, except ram set to 9-9-9-24)
  • LLC disabled
  • Ram timings set to 9-9-9-24 (from 8-8-8-24)
  • Intel Speedtech disabled
  • HT ON
  • CPU Voltage:1.28ish
  • CPU PLL Voltage:1.80 <--minimum voltage
  • QPI/DRAM Core Voltage:1.28ish
  • IOH Voltage:1.1 <--minimum voltage
  • IOH PCIE Voltage:1.5 <--minimum voltage
  • ICH Voltage:1.1 <--minimum voltage
  • ICH PCIE Voltage:1.5 <--minimum voltage
  • DRAM Bus Voltage:1.64
  • DRAM DATA REF Voltage on CHA:AUTO
  • DRAM DATA REF Voltage on CHA:AUTO
  • DRAM DATA REF Voltage on CHB:AUTO
  • DRAM DATA REF Voltage on CHB:AUTO
  • DRAM DATA REF Voltage on CHC:AUTO
  • DRAM DATA REF Voltage on CHC:AUTO

The test ran about 2 hours longer than usual but still failed



Memtest for windows, 4 windows open, 2750megs each, and I'm getting an error:



edit: Now I've got 4 total errors so far (2 windows have 2 errors each).

This may seem a dumb question, but did you add more RAM to your system since you OCed it the first time? Because more RAM might require more Vcore from your processor, meaning the thing hasn't degraded at all

Regardless, I'd try giving your QPI voltage a bump. Try 1.3.
