Windows 7: Memory_Management BSOD

Can you give some laptop hardware specs?

OEM computers are very limited when it comes to BIOS settings and adjustments.
Your manual has no reference to being able to adjust any settings or voltages in the BIOS.

When you get no errors in memtest86+ with one RAM card installed at a time in all the RAM slots, this tells you that the RAM is good.
If two RAM cards are installed and you get errors, this tells you that RAM needs setting and voltage adjustments to run stable, since you can't make any of those adjustments you need to RMA or replace the RAM.

Try running your laptop with one RAM card and see if you get any crashes.

If you decide to replace the RAM yourself, due to the expense and hassle to do it from where you are now, make sure the RAM has a good return policy (try PC HUB) and get the timings and voltages required from Sager.
The wrong RAM specs won't run on your laptop.


Let us know what you decide to do.

The thing is that it both happens for when BOTH kits are installed either in slot1/slot3 or slot2/slot4 config. It seems that it is less likely that all mobo slots are broken, right? I think it's compatibility?
If both kits were not from the same package it is the most likely cause.

Win 7 is very RAM sensitive.
Ok but they are the same package with the same serial number. I don't know.

Memtest86+ is not Win7 though. Oh and by the way, I heard that HCI Design MemTest is better than Memtest86+ and when I've tried running it it produces error for even just running it for 1 minute. And I've read that usually test#5 errors indicate frequency, timings, and voltage problems. Unfortuantely, my laptop BIOS is not flexible in changing those values.

Sorry for the double post. I take it that you are from the Philippines since you know PCHUB and tipidpc?

These are the specs of my laptop:

Sager NP8130
95% Gamut 1080P Glossy Screen
i7-2670QM
GTX 560M
2x4GB Kingston HyperX PnP 1600MHz RAM
128GB Crucial M4 SSD
Seagate 500GB 7200.4 HDD

And yes you are correct that my laptop's BIOS doesn't offer any options in changing timings, voltages, or frequencies for the RAM modules. So the real problem is the RAM then? The modules I have require 1.5V which is the standard for all Sandy Bridge platforms including mobile ones. They ran at 9-9-9-27 as well which is a very relax timing configuration.

Your motherboard won't run the two RAM cards, you need to RMA them.

CPUs and RAM all have different levels of quality, some 2x4GB RAM kits will run in your laptop and some won't.
Best voltage for all i-series CPUs is 1.5v.
All RAM chips are tested and rated, this is called binning, the better ones are used for tighter timings and higher frequencies.

If you could bump the DRAM and IMC voltage a little, that RAM would run stable.

Yes, I always do that for my desktop. So if I RMA the two sticks with the same brand and model, is there a chance that they would work?

Yes, a chance.

Probably 80% of a good brand of RAM will run 8GB at that frequency and timings.

Ok. I take it that the problem lies most probably with the RAM and not the CPU, right? Technically, the CPU I have is rated up to 1333MHz DDR3 only but I'm running a PnP RAM kit which automatically runs the kit at their JEDEC rating of 1600MHz.

Btw, I've tested with 2x2GB 1333MHz kit and there were no errors using HCI Design Memtest. Does this info mean something?

In my desktop I have an i5 2500K which is also rated up to 1600 MHz DDR3 only but I can run 4x2GB 1600MHz modules with no errors at all.

I would check the RAM first.
The JEDEC and XMP settings will adjust your CPU/RAM multiplier and run at 1600MHz.

I haven't used HCI, all the RAM, OC'ing and motherboard sites use Memtest86+, I would go with the information that it gave you.
RAM manufacturer sites will take a memtest86+ error report for a RMA approval.

Each computer system has different components that work together differently, just a fact of electronics.
Have seen many times that the same RAM kit will work in one system but not in another identical system, without some setting manipulation.

Ok. By the way, I just finished 15 passes of Memtest86+ with the 1333 MHz RAM and had no problems. I think it maybe the previous RAM then. I will have it RMA'd and see if something will improve. If not, I think it is compatibility that's the problem?

How many RAM cards and how many GB per card was the 1333MHz that you tested?

Best thing is to RMA the RAM, the new RAM should run stable.
Let us know the outcome.
