definitive i7 temps?

Just looking at your screenshots and remarkably similar to the i7 920 I've just got stable at 4ghz. :)

I'm seeing 74-73-72-70 on my 4 cores under load, running Prime95 for 12hrs and 1hr+ of LinX - and 41-36-36-34 on idle.

Some more tweaking to do yet though :)
 
When I first applied the MX-3 my idle temps were sitting at 37 on the hottest core, but I have just put the heating on in my house as it was getting chilly, so the idle temps shot up as a result..

But my loads are fantastic now, much better than what they were prior to using MX3..

Which cooler are you using mate, TRUE?

::edit::

I don't like the fact that there is a 7c difference between my last core and the hottest one, I thought it was a bad mount that was causing this, but I have tried reseating the TRUE several times now, and it just doesn't change.. however it is better than it was with AS5, I was seeing a 10c difference between these cores before applying MX3.
 
I've put on a Megahalem with push/pull Apache's - and I've tried the TIM that came with the cooler - though I do have some AS5 and MX-3 lying around if I'm not satisfied -plenty to choose from, but so far so good :)

It's in the same room as a couple of other quad machines, so with the door closed last night ambient will have been reasonably warm as the other 2 were rendering.

Edit: In reply to your edit. I wouldn't worry about it too much - if you're happy the cooler is on correctly and the cores are within safe limits (which they are) - then no point worrying :D

Yeah you are right enough mate, I just found it a little strange that there is such a wide gap between the hottest and coolest core, my other 920 only has about a 4c difference.

Like I said, I thought I had a bad HSF mount, but I have tried reseating several times now and it doesn't make any difference at all..

I might try the TRUE washer mod to see if that makes any difference at all, though I very much doubt it will, I think that mod was only really to stop the TRUE from being able to be twisted, although when I tried it with my last 920 that was faulty it did knock like 2c off my temps, so it can't really hurt to try it again.
 
My first quad was a QX6700 and that had 7-8 degree difference no matter how many times I reseated the cooler.

It's still going strong almost 3 years later, although it has always been a poor overclocker due to the heat it puts out - a Q6600 G0 I've just sold was stronger for a fraction of the price lol - but it taught me to stop worrying about core temp differences :)
 
I wont lap my chip as that will void my warranty... I will just live with these differences in core temps.

I've managed to get my chip LinX stable at 4.2GHz tonight, I am well happy, and my temps are pretty good considering I'm just on air cooling.

These temps are lower than what bulldog posted with his Corsair H50 and his chip o/ced to 4.2GHz, so I am quite chuffed about that tbh, I didn't think the TRUE would be able to outperform the H50 but I was wrong obviously...

I have my Vcore set to 1.34500v or there abouts in the BIOS, and QPI is @ 1.395v, but I haven't tweaked this o/c yet, so I could probably get these voltages down a little bit tbh..
 
Very nice Davy :)

Going to run this one at 4ghz for a while - even though I've done full prime and linx stability tests - and see how it performs - on my render farm it's doing 2 to 3 times as many frames as the first gen quads @ 3.4ghz and barely anything in it with my C0 @3.6 as expected - though this isn't an accurate way of measuring it gives me an idea of relative performance.

I agree with you on the temps, I nearly went for a H50, but there seems to be a lot of mixed results with them, in the main no better than a good air cooler - but obviously neater.

Let us know how the 4.2 goes :)

Gaidin, you seem to have some of the best results I've seen with the H50.

At 4ghz you're running a little lower vCore than me, but your temps are almost identical to mine with a Megahalem.

I'm running 1.287vcore at 4Ghz, but I do not have Load Line Calibration enabled so I get a bigger vdroop, but this seems to give better load temps overall., also QPI is 1.215v, a lot of people are running 1.335v for some reason. Also my memory is running at 8,8,8,24,2T set manually in bios with 1.5v instead of 1.65v.

My Megahalems were slightly higher temps than the H50, and the H50 looks better, takes up less room. I'm a big fan of the H50.
 
Gaidin, see how you are running your VDimm at 1.5v, have you tried setting it to 1.65v and then trying to tighten up your timings for better performance?

I should think your modules would run a good bit tighter than what they are currently, you could try have them at 8-7-7-21-1T, or even try 7-6-7-20-1T.. though you might need to use more than 1.215v uncore to get it stable, but it would be worth it.

The reason some people are using 1.335v uncore is because that's what their chip requires to be stable.. but you knew that, right??

The amount of Vdroop I get with LLC disabled is ridiculous, .9v or something like that, whereas with LLC enabled I only get about .2v.. and I find it much easier getting my system stable with it enabled to.

Do you still have your Megahalems?

p.s. you should set up your trust account here mate.. then you get access to MM..
 
I set the 8,8,8,24,2T timings as they are the XMP profile, tightenen up some more isnt going to improve performance that much, but raising the uncore is going to raise temps so its not worth the aggro. ( i also like the fact that the overvoltage lights are unlit on the Mobo.:)) I read an interesting article about the bandwidth supplied by DDR3 memory being more than the CPU can handle anyway. Anandtech i think.

What I meant with the 1.335v uncore is that, there is a lot of people who bought the bundles and that is what is set as default in the profile, and reducing it may be fine. There are people who concentrate on the vcore and nothing else.

my vdroop is 0.8v, but the 4ghz load needs 1.2v so thats ok. with the 4.2 profile that needs 1.312v in bios and 1.28v under load so 0.8v vdroop is too much so I enable LLC to compensate.

I have sold my Megahalems on now, the Fenrir I also had fell apart.

I dont use ICQ or MSN or anything like that so a trust account isnt worth it.

I have just updated the Gigabyte UD5 bios to F9e and it seems to have reduced the vdroop slightly, I have got to do some testing but preliminary IBT is about 2c-3c lower.

although ET6 now reports garbage in the BCLK and QPI speed boxes and thinks I have a Gainestown cpu.????

The update is supposed to fix cpu abnormal temperature according to the notes.
 
I downloaded that BIOS when stasio from XS first put them up, though I haven't bothered testing it out yet..

When you mentioned people using 1.335v uncore, I didn't realize you were referring to people who bought the bundles, I thought you were meaning i7 users in general.

Do OcUK just use the same BIOS settings for all of these 4GHz bundles do you know?

You are right about the RAM timings, you wont see a difference in day to day use, but if you are into benchmarking like 3d mark, Super PI etc etc then you will see improvements with those types of things, but if you don't run stuff like this to push your PC to get higher scores then there is no point in tweaking stuff like this.

::edit::

About the trust thing, I never mentioned it for anything to do with MSN or ICQ, I dont use those things neither, it was so you could gain access to the members market, for selling and buying stuff from people here, I have got loads of great deals from there, my 2nd UD5, G15 keyboard and MX518 mouse, EK GTX280 block, and pretty much all my other parts for my upcoming custom loop has came from there, it has saved me a fortune to be honest, I love buying stuff off MM!!!

I'm not sure, I know that they sent me a pretty generic profile which didnt show any evidence of tweaking whatsoever. It was way off what the CPU was capable of. I bought one for the quarantee of a 4ghz cpu, and luckily I got a good one. so it was worth the extra cash.

Thanx for telling me about MM, I didnt even know it existed tbh. I'm pretty new to OCUK forums. I'll get on that as soon as I qualify, (90days)

this is the one hour primeblend for the F9e bios, seems to be a couple of degrees lower, I was getting 72c-73c with similar ambient and case temps before the update.
 
I will give F9e a blast tomorrow mate.

About MM, it is amazing!! :D

I got about £150 worth of watercooling gear for less than £100!!!

I got my 2nd UD5 for £140 and it was unused to, this was when they were still like £209 plus postage.. can't grumble with deals like that!!!
