Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

As for your temps, I think you applied too little TIM or you have some air bubbles there... 10C difference between cores is too much. Plus hitting 81C on 1.26v with decent cooler doesn't look right. With 25C ambient (2-3weeks ago was 30C+, hrrrr...) and 1.3v vcore 4ghz, I'am in the very low 60s (prime95 small fft) using EVO 212.

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Woo! Small FTTs passed also! Here's hoping blend will be ok!!!

Smoger I think you're right, I will do some TIM re-application soon!

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Well blend had passed 5 hours when I had to leave... 72 hours later it turns out worker 2 failed after 12 hours - there was a popup notification from my printer so I'm wondering if something like that may have affected the test?

Repeat the test or change settings?

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

• 8 hour small FFT test: 8 hours with no errors
• 8 hour large FFT test: 8 hours with no errors
• Blend test: one worker error after 12 hours & no errors after 72 hours for the remaining worker threads

Call it good and move on.

TIM application
Too little or too much TIM can cause higher cpu temperatures.
A cpu cooler that is improperly tightened can also cause excessive temperatures.
TIM coverage that is inadequate can cause one or more cores to run hotter.

The top picture shows your cpu cooler orientation earlier in the thread.
The bottom picture shows the orientation of my cpu cooler using a single, 2000 prm pull fan setup.
The cooler's hot air is exhausted out the rear of my case and I removed the 1200 rpm fan from the rear of my CM 690 case.
There is about 23mm of clearance from my cooler to the tall heat spreader's of my HyperX T1 memory.

You might have better cooling results if you rotate your NH-U12P cooler so that it exhausts hot air out of the top of your case.
You might need to remove the current exhaust fan at the top, rear of your case.

I've had excellent results recently by spreading the TIM with my finger in a small plastic bag.
I spread the TIM as thin as possible and don't go to the edges of the cpu.

Some TIM's do not spread evenly no matter how much you try.

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Thanks Jim! I tried to mount the cooler rotated 90 degrees but it didn't fit :/ I think it was blocked by the Northbridge cooler - can't quite remember... I will definitely have a go with the 'plastic bag over finger' TIM application method.

Next up, let's try 3.85GHz :) Start with a few clicks of vcore?

[profJim]

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

With a 50MHz cpu speed increase, I would set vcore up one click to 1.40000.
If you are manually setting DRAM Voltage (2.10 volts) and MCH Core (1.24 volts) you might want to try the AUTO setting and see how that works out.
With Cpu Core voltage = 1.40 you might need to increase VTT from 1.34 to 1.36 volts.

You might not be able to rotate your cpu cooler.
Based on my cooler's 100mm width and only 23mm of clearance, your NH-U12P's 126mm length might not fit with your Hyper T1 memory's heat spreader.

In one of your earlier TIM photos, the "dot" of TIM was off center and this could cause higher cpu core temperatures.

[lukevega]

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

I'll get on it! Do I want to try auto settings for both DRAM Voltage and MCH core or should I try single changes at a time and see what happens with just vcore/vcore+VTT?

Here is a picture of my current TIM (taken a while ago but never uploaded):



Hopefully it will explain some high temperatures and be easily improved upon!

[profJim]

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Your TIM photo looks good, but try the finger in a bag spreading method using a similar amount of TIM.

I've found that using the AUTO setting for DRAM voltage and MCH Core gives values that appear to be too low but they work OK.
I would change both of these settings to AUTO and then test.
It will be best if you note these specific AUTO settings in your detailed posted settings screen-shots.

As stated earlier, never use the AUTO settings with Cpu PLL or VTT (Cpu Termination) when overclocking.

It might save you some time if you run three separate preliminary 2 hour Prime95 stress tests assuming that none of the tests generates errors.

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Hm.. I don't think that line of TIM is right.



It's either a dot, spread or horizontal line slightly above the center.

BTW, I'am thinking about delidding one of my X5460's,
so I might be able to see the die alignment with my own eyes and take some photos.

Golly gee, now I feel bad that my quad core cpu doesn't look as pretty as the stylized Intel marketing drawing.



Arctic Silver has recommended TIM application methods for different Intel and AMD processors:

If you go with the finger in a bag spread method, you're covered if your TIM spreads easily.

Years ago I gave up on using a credit card or razor blade to spread TIM evenly with an ultra thin coating.

Delidding a cpu where the die is soldered to the cpu heat spreader?

[SmOgER]

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

Yeah I got an mixed opinions on as to whether it's soldered in or not. Apparently some of these Xeons aren't soldered, but not all. So I sacrificed my extra X5460 (c0) for the sake of science. :D

Looks like the cores of X5460 are BELOW the caches, not on top like in previous pic from Q9550. Also, there is no caps like in some of C2Qs.





I've got a feeling that E0s are not soldered, since the temps seem to be volt-for-volt higher on them than on C0s, at least on my particular chips the difference was some 10C, it's just that E0 typically needs less vcore by almost 0.1v, so it still runs cooler clock-for-clock.
And no, I'am definitely not delidding my main E0 X5460 nor trying to do so. :D

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

lukevega, how much you paid for GA-EP45-UD3P? That's arguably the best overlocking mobo for LGA775 ever made, I'am surprised you are having such a hard time with it.
I was today looking for a mobo replacement myself, it was either GA-EP45-UD3P or a good DDR3 board. I just couldn't find this Gigabyte at acceptable price, so I bought MSI x38 Diamond instead. I hope I will at least break that 421FSB which I had with P5QC. That ASUS board wasn't terrible, in fact it could post and somewhat boot at 500FSB, but memory controller was just going bananas with both Kingston HyperX Genesis (2x 2GB DDR3-1333 CL7 1.65v) and Corsair Vengeance (2x 4GB DDR3-1600 CL9 1.5v) kits and anything above 421FSB. I loosened the timings so much that the memory bandwidth dropped from 10 000MBps to 4500MBps but it was still unstable even then (prime95 blend failed after 1 hour) Using only 1 RAM stick didn't help neither.

Re: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

OK it looks like I made a rookie mistake... X38 is not compatible with X54x0. Damn! I knew that, but totally forgot since it was irrelevant for me at the time... I hope the seller will kindly cancel my order before shipping so that I wouldn't have to wait just to ship back...
