Problems with 1GB Corsair Valueselect and DFI LP UT250gb

[DarkCharisma]

I had a 1GB kit of Corsair Valueselect PC3200 (512x2) in my PC for about a month now, working smoothly. Just recently, I started getting BSODs that seemed to reference to the memory. :(: I got two of them today within an hour of each other. I ran Memtest86 when I first bought the memory and it came back pass without any errors. I am currently running the test and within 1 hour I have returned with 34 errors and possibly counting. :confused: What could have happened to make it do this? I do a lot of computer gaming, photo editing, and video editing on my PC, but I don't think that it would hurt it. I try to keep my PC in optimal conditions at all times, and most of the time it is, but for some reason it returns these errors now. :eek:

 

This is my system:

 

AMD Athlon64 2800+ (skt754)

DFI Lanparty UT 250gb

Corsair Valueselect 1GB Memory Module Kit (512x2)

Western Digital 120GB 7200RPM on Master IDE

CD-ROM and CD-RW on secondary IDE

Nvidia Geforce FX 5200 AGP 8x, 128MB.

 

Any help would be greatly appreciated.

 

Regards,

Chad :):

Someone here has got to know... and in the off-chance that no one does, is there any way to fix memory errors? Or are they permenant?

Can you tell me the bios settings you have set for both CPU and memory and any performance settings that you may have set?

[DarkCharisma]

Certainly. My CPU settings are all at default, my RAM settings were at DDR400, but then I set them back to auto, and all my voltages are default. Really the only thing I touched in BIOS was to disable sideband addressing and fastwrites on my video card and to change the boot sequence.

 

The only part in my PC that was ever overclocked was my video card, and that was through Nvidia's coolbits 2 clocking interface.

 

I hope this helps, please holler if you need more information...

Chad,

With a 2800+ CPU you would need to run the memory at DDR333 so its in sync with your CPU. Or it will cause a bottelneck in the chipset and may generate errors that are not the fault of the memory.

Example:

CPU Freq: 166 MHz

Memory Frequency: 100%

Dim Voltage to 2.7 Volts

Resulting Frequency: 166MHz

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 3T

SDRAM Active to Precharge Delay (tRAS): 7T

And then test the system with http://www.memtest.org to be sure its stable.

Oh okay, thanks a million Ram Guy!

[RAM GUY]

Please let me know if you still have problems, or any questions.

I was looking at those settings again in my BIOS, but now I'm confused. :confused: Isn't my CPU FSB supposed to be way higher than 166MHz on this 64-bit 2800+? And the same for this RAM, shouldn't it be able to run at 200MHz if my CPU FSB is at 200Mhz? And lastly, can this Valueselect run dual-channeled?

 

I did a little googling and realized that I don't know anything about my CPU. On a side note, is there an accurate resource out there for me to learn about what all those numbers in the bios mean?

[RAM GUY]

Please make sure you have the latest BIOS installed for your MB and load optimized defaults settings, and try the following BIOS settings;

VS512MB400 or VS1GBKIT400

Genie BIOS/DRAM Configuration

DRAM Frequency Set: 2:1 or 400MHz or 200 (if option are 133/166/200)

Command Per Clock: Disabled/2T

SDRAM CAS Latency: 2.5T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 3T

SDRAM Active to Precharge Delay (tRAS): 8T

Genie BIOS

Clock Spread Spectrum: Enabled

CPU/DRAM ratio: 1:1 or 100%

DRAM Voltage 2.75 volts

AGP Voltage: Default *unless you have ATI 9200 or 9600 then 1.6 Volts suggested!*

All other settings are motherboards defaults

Then please test them one at a time with http://www.memtest.org and let’s make sure it's not some other issue! I would run the test for at least 2-3 passes to be sure!
