BSOD/Freeze After Adding Ram

Post by goinundercover »

I've been running 4GB of DDR2 1066 ram for quite awhile, and decided to upgrade to 8GB. I found an identical set of sticks with the same part number as mine, and purchased them. Stuck them in my case yesterday and either won't boot, or will freeze up or BSOD within 3 minutes of booting.

Specs:
CPU: Intel Core 2 Duo E8600 Wolfdale 3.33GHz (stock cooler)
MOBO: Gigabyte GA-EP43-UD3L (rev. 1.0)
RAM: OCZ Reaper HPC 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)
GPU: Sapphire HD 7850 1GB
PSU: Tuniq Potency PSU-POT550-BK 550W
HDD: Some Western Digital HDD @5400rpm and not close to being 1/4 full

Links:
CPU: http://www.newegg.com/Product/Product.a ... 6819115054
MOBO: http://www.newegg.com/Product/Product.a ... 6813128380
RAM: http://www.newegg.com/Product/Product.a ... 6820227289
GPU: http://www.newegg.com/Product/Product.a ... 6814202004
PSU: http://www.newegg.com/Product/Product.a ... 6817611006

Only difference I see with the new sticks and my old ones is that my old ram's pcbs were black, and the new ones are green.

I tried booting with both of the new sticks only, and rarely got to login to windows, and ended up freezing or BSODing. I put them all together, with my ram in slots 1 and 3, and the new ram in slots 2 and 4, and the computer became significantly slower to boot and would freeze more often than BSODing.

I then ran memtest86 on the new sticks, one by one, and no errors came up (5 passes). I then put all my ram together, with the new sticks in 1 and 3, and my old ones in 2 and 4, and ran memtest86 overnight. No errors came up the next morning, and 5 passes had been made.

I'm extremely confused on why my computer is BSODing.

Try going into BIOS and putting your RAM settings to the recommended ones by the manufacturer.

800Mhz
2.1V
5-5-5-18

edit: I see you!

Tell me how that goes, if it doesn't work out PM me your Steam or Skype name so I can try to handle this more directly.

Changing the Mhz was more complicated than I thought, as it required the multiplier and something about the FSB. I ended up reinstalling Windows 7 as my rebooting/testing with the ram caused chkdsk to do something and essentially messed up my drive every time I attempted a boot up. Tell me if there's anything I need to change via this CPU-Z output:

Doesn't seem to be crashing now, not really sure what happened in the end.

Uh yeah, chkdsk can really fuck a hard drive if used incorrectly or if you fuck with it (turn off the PC) while it's working, which might've been caused by the RAM failing which is a shame.

I'm assuming that it's really picky about it's timing and voltage settings when being run at it's max 1066Mhz clock speed, whereas setting it down to 800Mhz should give it a little more leeway.

If it runs stable now I'd just leave it at 800Mhz, the fractional performance increase running it at 1066Mhz isn't worth constantly crashing or losing important data, I hope you had your stuff backed up before installing it. If you really want to take advantage of it's highest speed setting then I'd suggest doing some more research into what exact settings it should be running at.

edit: It seems that your module pairs seem to have different voltage requests for 1066Mhz as well (one is set for 2.1, the other 2.2), looks like they weren't as identical as they should've been. Though it seems you installed them into the correct (alternating) slots for dual channel, cheers.

Also a lot of people complained about it not running stably at 1066Mhz.

Yeah, when chkdsk ran, it started doing a bunch of "replacing invalid security file with default" or something. It ended, and I ended up with a black screen every time. So every time it did that, I'd just force shut it down.

So far running at 1066 for about 3 hours, ~45 minutes of tf2, and everything seems relatively stable.

I didn't have anything backed up. I have an external hard drive->usb dock so I plugged that into windows. Unfortunately, windows doesn't like the second partition, and kept denying access. I used my laptop and booted into linux via an old usb, and managed to transfer my vital files that way. Everything else I just downloaded and reinstalled.

Old ram in slots 1 and 3, new ones in 2 and 4. Never noticed the voltage difference, guess same part # ram isn't the same after all...

All hail the power of Linux and USB booting.

So very useful when recovering dead laptops' hdds. And hacking school computer passwords.

I think I found out why my computer kept crashing.

My settings for the CPU FSB was 353 using a x10 multiplier for a slight overclock.

My settings for ram was auto, which I think defaulted to 333. When I reset my BIOS to fail safe defaults and changed the timing manually, it made the cpu have no overclock at 3.33 ghz and my ram was set manually to 333.
