there have been 2 month since i've got this pc and there is this serious problem that is blowing up my mind: sometimes when i'm playing games the system crashes (that blue screen appears). after reporting the error, it tells me it's a "corrupted error" (something bad i guess). infrequently this happens even when the computer is idle.

here is my system:
cpu - intel dual core e2180 (with stock coller)
ram - 2 gb corsair xms2
mobo - ecs with integrated video chipset nVidia 7100
power supply - 350 W

i think what makes it unstable is the power supply (350 W is too low). maybe anyone has experienced similar problems or can guess what is going on here. what needs to be done to make clear what is causing this? can i do anything in the power options (control panel)?

any thought from you guys would be much appreciated, need to solve this.

thanks !

Driver issue...possibly...windows driver.

actually one of the errors said it was a usb driver error, but this happens even when i'm on ubuntu (linux). there is no blue screen but the system freezes and two of the tree lights above the numpad on the keyboard start to pulse. thanks for the link

do i need to remove the plastic cover from the ram? is it meant to be placed with that?

Reply to ichundu

I would check heat and drivers before you reformat your hard drive. Also don't remove the plastic (I assume you mean the plastic on either side of the ram). That plastic is fine.

the cpu temps vary from 35 to 45 C, don't think it is hot. i'm downloading the drivers from the site, maybe those on the cd are bad...

i did run the memtest86+ for 2+ hours and no error was found (the test didn't stop by default). so am i guaranteed now that ram is ok?

Reply to ichundu

Memtest86+ doesn't guarantee anything. What I mean by that is, you could have the wrong memory settings in the bios to produce errors on the program test, and think the memory was bad.

You mentioned USB device.

What device are you talking about?

Also was that device present on the system when your PC crashed?

Are you sure you have the most updated drivers for the MB chipset, which would be some what related to all integrated devices?

If you believe its the PSU, do you know anyone who could lend you one for testing?

the error report troubleshooting was about usb driver, not about any particular usb device. the memory settings in bios are set on auto. FSB : DRAM ratio is 1:2 (DRAM frequency is 400 MHz). ram clocks are 5, 4, 4, 17, 22. i'm not overclocking

i hope it is just a driver issue :pt1cable: , i used those found on the support cd. anyway i'm gonna try the drivers i got on the mobo site.

i took out the ram and reinstalled them. i played for an hour and nothing happened. i hope the problem is gone :wahoo:
i'll make some stress tests and i'll let you know if the problem continues

thanks

i made a stress test with orthos 2006. didn't get the blue screen of death this time but got my pc beeping and this message:

it tells me to consult stress.txt file, but it is nowere.

the temp of cpu during test was up to 56 C

Hmmmm.

Chances are the ratio your using, maybe the problem.

Can you do a validation link on CPU-Z? (like below)

i'm trying to link the cpuz screenshot but can't do that. how do i exactly do that?

i'm writing what i see on cpuz (memory tab):

General

Type - DDR2
Size - 2048 MBytes

Channels # - Single


Timings

DRAM frequency - 400 MHz
FSB: DRAM - 1:2
CAS# Latency (CL) - 5.0 clocks

RAS# Percharge (tRP) - 4 clocks
Cycle Time (tRAS) - 17 clocks

ok i got that grimmy.

here's my validation link:

Okay, your using CL 5 ram. The timings are 5-4-4-17. Try setting them 5-5-5-18 in your bios manually (leaving the rest on auto) but also manually set the memory voltage (guess its 1.9v). Once you done that, then try to run Orthos again to see how far it goes.

I did found a site that is perhaps similar to your MB, not totally sure. I did d/l a manual on the MB but it doesn't talk much about adjusting the timings. That is where I found another site that had similar bios settings:

 

ECS GF7100PVT-M Review

 

Edit:

 

Pic on the memory timing screen:

Hope that helps some.

yes my mobo is almost equal to that (except it is M3 at the end of the name and not jut M). bios is the same though

i did change the timings to 5-5-5-17 and stressed the system with orthos, like you said, and it run stable for 50 mins, then i got the same error. i was playing now to see how it goes and i got the blue screen. this time the windows error reporting said that the problem was most likely caused by the ram and that i should consider bios upgrade.

i'll try the 4-4-4-12 timing now.

grimmy, thank you so much for your posts

Reply to ichundu

Heh.. 4-4-4-12 is just how the guide shows you can set the timings. I didn't mean for ya to set it that way, but thats the timings for CL 4 memory, which you tightened, and might make things a lil worse.

The thing is, you matched a CPU with memory that is way too fast for it.

If you look at the CPU-Z stats you can get a clear picture of it. Your CPU is a 800FSB rated CPU. (just like my E4400) And the memory is DDR2 800. For that CPU all you needed was DDR2 400 which would match your CPU better for a 1:1 ratio. I was looking for a bios section to where you could actually run the memory slower, but it doesn't seem to have that option.

But looking back at the CPU-Z validation, your FSB is 200. Your dram or RAM speed is 400. I'm guessing the bios is not exactly doing a good job running the ratio properly. Maybe one thing that could help, is to raise the memory voltage.

Try going back to 5-5-5-18, and putting the memory voltage to 1.95, if it fails again, then try 2v. Other then that, not sure what else you can do for it, execpt replace the ram with DDR2 400, and setting the timings again manually.

Hope that makes sense. :sweat:

back to 5-5-5-18 :D lol

You know after thinking about it, if you could save up some cash, just go with a better MB. That memory you have is better suited for OC'ing.

My E4400 for example ran great at 2.8ghz without raising the vcore on it:

http://valid.x86-secret.com/cache/banner/257267.png

I run it as my linux machine, but I do have it a 2.8ghz rather then 3ghz as the CPU-Z specifies.

So you could get something like:

GIGABYTE GA-EP43-DS3L LGA 775 Intel P43 ATX $90

Note that is a full ATX MB, but it can give you a better upgrade path, but you still can run the DDR2 with the E2180

Or if it has to be micro, the only one I found which is really nice for micro ATX:

DFI LP JR P45-T2RS LGA 775 Intel P45 Micro ATX $165 - price will come down in time though.

I recently went to a DFI MB, but full ATX for $130 bucks.

But just trying to give ya alternatives with your current ram and cpu, that offer better bios features. It would prolly be more of a waste to buy DDR2 400.

Although if raising the memory voltage helped out, then great. :D

i don't know if i can get a new mobo right now, maybe some months later. it wasn't me who bought the parts. i would have never got a mATX mobo, even more from this OEM. there is little space to OC with my current one, there are only options available for 900 (?), 1066 and 1333 MHz FSB, but still need better cooler and PSU. and what to overclock for when you're using an integrated video chipset ?! :kaola: so i'll have to consider not a small change to my system. even if i do so i'm never gonna be sure i'll have no problem then (maybe one of the remaining parts is defective, i.e. ram)

PS: i'm now running test with 2V , not stable at 1.95V :cry:

Whelp.. all I can say is, I would not say the memory is defective. I'd say the ECS MB just won't work well with that ram, unfortunately.

I forgot your using integrated video card. I guess you have to even save more for PCI-E video card. :oops:

NewEgg does have DDR2 400 memory, 2GB kit:

Kingston 2GB (2 x 1GB) 240-Pin DDR2 SDRAM ECC Unbuffered DDR2 400 (PC2 3200) $43 bucks

Although I don't know if that's a store you can use.

definitively not stable even with 2 V. :cry:

i think i read a thread today saying that there are known issues with nvidia motherboard chips that affect ram.

Reply to ichundu

Whelp.. have you tried 4-4-4-12?

Might as well give it a shot, perhaps the timing could be too loose. Should perhaps leave the memory voltage at 2v, which shouldn't hurt it.

Reply to Grimmy

i tried that (with 1.9 V) but came back to 5-5-5-18. don't remember if i tested that but i think i didn't.

so you say to try it, so it'll be easier to decide for the ddr2 400 after killing my current ddr2 800. (just kidding lol :lol: )

Reply to ichundu

Heh, well the DDR2400 ram I listed use CL3, so why not.

And as a last resort, try 1 stick at a time.

Other then that I'm all out of fresh ideas for you to try. :cry:
