Windows 7: BSOD during Macrium Image creation

30 Oct 2011   #11

Windows 7 Pro-x64

It appears to me that your memory is running a bit under speed. I wonder if the modules are really 1.6v. Mfgs will sometimes report specs at 1.6v. That or your FSB is drooping too far below 100MHz. Memory speed on 667MHz module shouldn't vary by more than a couple of MHz. Yours is about 5MHz Also, the Command Rate seems high for 9,9,9,24 modules. CR for these is typically "1".

Thanks for jumping in Ken. I got some of that, but the rest is all pretty much gibbersih to my frail brain :) Is there anything you recommend I might try? I'm guessing making some sort of adjustment to RAM voltages in the CMOS?

I've never done anything like that before, so I understand I need to be pretty darn careful. What do you recommend?

In AWARD BIOS the Turbo setting under DRAM Timing Control reduces the CAS access time (latency) by 1 clock tick. Some RAM modules have some overhead in their timings and some do not (this is due to the industry practice of binning). So your first course of action should be to disable all performance boosters and set everything related to CPU and RAM in BIOS to normal, or default.

Time and again we have seen the condition where someone populates all 4 RAM slots on a motherboard and the board cannot maintain a constant voltage to all 4 modules simultaneously. Some people report success with increasing the overall RAM voltage which seems to correct the condition. Others have no luck with this but can get results by adjusting the timings (usually lowering them).

Both settings are adjusted incrementally in very small increases or decreases. It is usually 0.05v or 0.1v at a time for voltage, and you should not have to increase the voltage very much above spec. It is a tedious process. You make the change then run the system to see if the condition returns.

Some BIOS settings have voltage settings that increase by percentages. I'd avoid those and look for the voltage settings that let you enter the exact voltage.

And then there is always the possibility that one stick of RAM is too far out of spec compared to the other modules to operate smoothly with them. This is most frustrating because these sticks will easily pass memory tests like Memtest, which is just looking for bad registers.

Curious: were all 4 sticks sold as a matched set?

Hope that helps.

If your BIOS allows it, drop the CR down to "1". When four modules are installed, the BIOS may default to 2T but I don't think your modules are fast enough for that. The BIOS may allow you to set the memory voltage too but I would like to see what it's set at now.

If you have any other machine monitoring programs running (temp, voltage, fan, etc.), STOP all of them, remove them from your startup and don't allow them to add drivers. Reboot. Then download and run HWiNOF64 (64-bit). On the Sensor window, scroll down and take a snip of the motherboard sensors and post it. This will show temps and voltages at various locations. This is the ONLY one I trust to give valid readings.

If you'd like, go ahead and post a snip of the System Summary window also. This will show current timings.

Here's a screen snip of one I just ran.

Forgot to mention: You don't need the Driver and BIOS Agents. I prefer to get my updates directly from Intel when I want them. The Agents just add another level of "openness" to your system.

@TVeblen : thanks for the detailed description, I have defaulted back to the "Standard" DRAM setting from "Turbo". So far the system has not yet BSOD'ed, but that could be luck more than anything else. The RAM was sold in invidual sticks, not as matching pairs.

@Carwiz (Ken) : I have no other monitoring software in startup, and have uninstalled Speccy. Here is the screencapture from HWInfo64 as requested. I haven't yet tinkered with the BIOS : I thought I would just paste the info before doing anything more so we have a base to work from.

In HWInfo64, I see the CR = 2T value, but I don't see a DRAM voltage setting in the sensor I missing something? I also captured the Memory information in case that is of use to you:

Hi Golden,

When using 4GB or more RAM, more than 2 RAM cards, you might need to bump the CPU integrated memory controller voltage. Sometimes you might have to bump the DRAM voltage.

You will have to get your CPU integrated memory controller and DRAM voltage from the BIOS.
Check in your motherboard manual: GA-P55A-UD3R (rev. 1.0)
MB Intelligent Tweaker(M.I.T.) > Advanced Voltage Settings, page 43.

Bump your CPU integrated memory controller voltage, qpi/vtt voltage in your BIOS, to 1.20v. Default setting is 1.10v and is aimed at standard users with 4GB RAM or less.
If you still get BSoDs then bump you DRAM voltage to 1.55v.
Be sure to keep the DRAM voltage and the qpi/vtt voltage within 0.50v of each other, this is the Intel CPU (Integrated memory controller) requirement. This will keep you from damaging the CPU integrated memory controller.

I would leave your frequency at 1333MHz, 667MHz in the HWInfo64 snip.

The CR (Command Rate) of 2T is better when using more than 2 DIMMs or more than 4GB RAM.
The 1T setting is faster, but not as stable as 2T when you have lots of RAM, more than 4GB.
CMD: Command Rate. The time it takes between the memory chip having been activated and when the first command may be sent to the memory. Sometimes this value is not announced. It usually is T1 (1 clock cycle) or T2 (2 clock cycles).
With DDR3, which is very fast RAM, the difference between 1600MHz and 1333MHz is not very noticeable to the average user. Same with the CR (Command Rate) of 1T vs 2T.
It was recommended to use 1T with DDR RAM and somewhat with DDR2 RAM, but is only a small fractional speed increase for DDR3 RAM.

Try the above settings and let us know the results.
They should let your system run stable, if not then a little more tweaking.

Hi Colin, I agree you may need to bump up the CPU Memory Controller volts along with the DRAM volts too. Very small increments.
The CPU at 40C sounds too hot. I would have a look at the thermal paste, a pea-sized glop is too much and may have squished out on to other circuits. Use a good paste cleaner on the Noctua and the CPU completing with a good rub of 91% isopropyl alcohol. Use a rice-grain glop of paste. Lower the cooler and twist and press to spread the paste before tightening it.
I'm unsure how that cooler attaches, but if with screws or nuts, don't over-tighten it. It can warp the motherboard and cause BSOD.

The 40c was the maximum on Core-3. That's really not out of line. It's common for the individual core temps to be higher than the base temp. If you look at the CPU base, it ranged from 28-31c. That would indicate a good thermal transfer is already occurring.

The voltages look pretty rock steady. (Vcore will change.) The Memory voltage is listed as "DIMM" at 1.584v across the board. You can see that the processor was drawing from 2.758W to 83.125W and the voltages stayed solid so there doesn't appear to be any sag.

Oh yes, I had a "memory fault" and had CR backward. Dave is correct about 2T versus 1T.

Wow, thanks for all the great input guys.

I've done the following:

QPI/vvt = 1.190v (1.200v wasn't available - the next available was 1.210v, so I opted for the safer? lower setting)
I left DRAM = 1.500v (next increment available is 1.560v)

I guess its a case of monitoring now and see what there any other recommendations you can make?
