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

DDR2 OverVoltage Control__ [+0.3V] might be part of the problem.

Your memory is rated up to 2.30 volts and I'm able to run my 8GB of HyperX T1 memory at 2.20 volts using the +0.4V dram voltage setting.

It's possible that your memory might require up to 2.30V using the +0.5V setting.

Ignore Gigabyte's memory voltage warning.

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

Darn I wasn't noting the details :(

I'm not sure, the cold boots might have been before or after the Memtest86+ - might well have been both!

After I finished the test I changed the BIOS to turn off legacy USB detect (which was for running Memtest86+) and re-ordered my Boot priorities.

I had EIST and C1E both running during all the passed tests

I was also hasty in reporting the new BIOS settings. I just took photos of the screens so here is the updated and 100% accurate version of my current BIOS settings:

Should I change DDR2 OverVoltage Control to +0.5V and report back with a screenshot of CPU-Z, MemSet and RealTemp?

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

Changed the timings, Windows just booted fine. Now comes the fun (we wish) part.

snip

PCI-E OverVoltage Control_ [+0.1V]
FSB OverVoltage Control___ [+0.1V]
(G)MCH OverVoltage Control [+0.1V]

I'm fairly sure these are all set to +0.1V but I will double check...

Am I right to keep EIST and C1E enabled for the 8-12 hour HCi Memtest?

On a positive note, I think I can feel a better responsiveness from the system! :D

Yes, keep EIST and C1E enabled.

It's possible that (G)MCH OverVoltage Control [+0.2V] might be needed.

I don't know if increasing FSB OverVoltage Control will help.

Using the 4-4-4-12 timings is putting more demands on your system compared with 5-5-5-18 timings at 1.80 volts.


We really need to stop cross-posting at the same time.

Note: I was just about to post this reply but I took a quick look-see and lo and behold you slipped in another post.

DETAILS ARE ALWAYS IMPORTANT!!!

You need to type this statement 500 times and you're not allowed to use copy and paste.

100% accurate? Are you willing to bet your life on it?

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

I apologise for the lack and inaccuracy of some of the recent details. I think I get caught up in things sometimes!

I even keep a little booklet with the changes I make but I guess the timings of the cold boots was one of the recordings that you would make that I hadn't realised previously...

I will be extra stringent in looking for details and taking note of them from now! (500 lines would be torture!)

I'm going for a run but will increase the DDR2 OverVoltage Control to +0.5V when I get back.

Should I wait before increasing (G)MCH OverVoltage Control to +0.2V?

Thanks!

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

You can also prove some of your voltage settings using EasyTune5 or EasyTune5Pro.

Never have any version of ET5 running while you are running stress tests.

I have ET5 Pro set so that it never starts with windows, it only runs if I manually start it.



P35-DS3L + E6300 (R0), 3.50GHz [8 x 437MHz] + 8GB Hyperx T1 memory @ 874MHz 4-4-4-10 timings

note the common program bug where the reported cpu speed is 10.5 x 437MHz where 10.5X is the maximum cpu multiplier for my cpu.

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

patient must you be

Apology accepted, but....next time --> <-- 50 lashes with a wet noodle

I'm not into publicly humiliating anyone, but I can't stress strongly enough how important details can be.

If your enthusiasm and/or impatience gets the better of you, you'll end up wasting time and effort.

If you change too many variables at one time you won't know which one(s) hurt or helped.

[lukevega]

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

Ok. Back from my run, EasyTune 5 downloaded.

About to restart, change DDR2 OverVoltage Control to +0.5V and hopefully boot into Windows.

All other settings will remain unchanged! :)

[lukevega]

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

Well it seems to still be playing nice :)

I changed DDR2 OverVoltage Control to +0.5V and noted in the PC Health status menu that DDR18V = 2.096V (I don't know if this is important but I thought I would write it down anyways)

Here is a screenshot including EasyTune 5, CPU-Z, RealTemp and MemSet:



How are we looking?

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

2.3 volts for your memory might be too high, even though it is within spec.

With my 2 x 2GB of Mushkin Blackline 1066MHz memory (now retired) the maximum rated voltage was 2.1 volts but I found that the system "felt better" with 2.00 volts.

So you think that your system boots faster with the new memory, I call that the placebo effect.

I use a free program called Boot Racer that posts a screen every time you boot your system and it shows how many seconds from the start of windows to the desktop.



I completed a Memtest86+ 2-pass test with my 8GB of memory, and the elapsed time for the test was 2 hours, 15 minutes which is somewhat less than half the time for your 2-pass test with 4GB to complete.

Homework: What are the 3 primary reasons why my elapsed time wasn't twice as long as your elapsed time.
There are 4 primary reasons, but I'm not including my karma as an answer.

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

That sounds like a tough assignment!

You must excuse me if I'm mistaken but I thought my 2 pass test took 1 hour and 23 minutes... :/

Other than that do I need to go back to the BIOS and change DDR2 OverVoltage Control to +0.4V?

[lukevega]

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

... and the system just froze :(

Bluescreenview didn't have an entry though :/

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

Your screen-shot looks good.

With EIST and C1E enabled, the cpu speed should be lower, possibly as low as 6 x 411 = 2.466GHz when there is a low load on your system.

The RealTemp elapsed time shows 18 seconds, but that is from the time you started RealTemp or reset RealTemp's statistics.

In post #200 I replaced the original ET5 screen-shot from the web with an older screen-shot from my P35-DS3L system.

Right now I'm one hour into a four hour HCI Memtest run with my cpu vcore = 1.36250 and so far, so good.

I think that my system will fail the LinX using all available memory, about 5500MB.

It's not helping things with my ambient temperature = 27^o(C).



Arrrg, you just snuck in another post.

Leave the dram voltage at 2.30 volts for now.

Yes your 2-pass test took 1:23 so with twice as much memory, shouldn't my test have taken 2:46 to complete.

I just did some quick math where my 2:15 test took 135 minutes to complete and your 83 minute 4GB test would have taken 166 minutes to complete with 8GB. According to my math, 166 divided by 135 = 1.23 (rounded) so my system was about 23% faster.

Need I repeat my question?

[lukevega]

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

Oh man my brain is NOT working today

I will change DDR2 OverVoltage Control back to +0.5V and then I will try and research the answer to my assignment.

[lukevega]

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

Not sure if this is the correct answer but here's my first attempt:

"The time necessary to complete the testing process can vary greatly, depending on the capacity and speed of the RAM that has been loaded, the FSB (Front Side Bus) speed of the CPU or other factors specific to the test board"

Reference: RAM Testing - FreekiWiki

I got confused with the question as you said that your test completed in "somewhat less than half the time" than my test - I hope I don't sound pedantic here, I just mean to explain why I was unsure.

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

Bluescreenview didn't have an entry though :/

I changed DDR2 OverVoltage Control to +0.4V...

....GRUMBLE, GRUMBLE, GRUMBLE.....

Where did it freeze? While booting? At the desktop? While running a test? !!!DETAILS !!!

There might be some useful information in the HWiNFO log file if you start it shortly after booting, including how long your system had been running and if there were any excessive cpu loads or temperatures that were too high.

It might also help to save a screen-shot shortly after booting that displays voltages and other information before you start testing. This way we might see something that doesn't look right.


This reminds of question I sometimes post in the forum; would you ever do this?

Hey doc, I've got a headache! What's causing it?

Homework Assignment

We have similar memory, similar motherboards and cpu speeds that that are within 100MHz.
Hint: It has something to do with the different FSB's; 411MHz vs 445MHz even though the overall cpu speeds differ by only 2.6%.

• Do you think that your looser 5-5-5-18 timings might have hurt your performance compared with my somewhat tighter 5-4-4-12 timings?
• Memory speed 822MHz vs 890MHz.
• Using Performance Enhance = Standard vs Extreme?

Hey, maybe my karma does have something to do with my faster performance.
