PC3200 XMS failure

Recommended Posts

Okay, I bought this RAM about 4-5 months ago, and honestly, it didn't work the second i put it in. I could boot, but once i started running a program, it would crash. Give me the blue screen on xp (memory dump) with and without my other ram. I checked the timings, they are 6-3-3-2 (like the RAM specifies) and the clock on them is 400 mhz. I donno what is wrong, i tried in 3 different comps all with diff mobo's and CPU's so it has to be the stick. I haven't had time with school and my job (plus no car to mail back) so i'm past the date on Newegg to send back to them, but it says it's a lifetime warranty so I'm trying to send back to you guys so I can get a new stick.

CPU AMD Athlon 2600+ (2.06 ghz i think and a 333 FSB)

Mobo = Asus A7N8X Deluxe

Made sure the timings were at 6-3-3-2, however when I took out my old RAM and put in just the corsair stick, it worked at 8-4-4-3, which is much slower then advertised and i can't run my other RAM at that speed either for some reason.

 

Everything is at default in my BIOS for the most part, i know the RAM voltage hasnt' changed and neither has the CPU voltage

Please load setup defaults in the bios setup and then set the following timings with the modules in slots 2-3 then test the system with http://www.memtest.org

CPU Freq: 166 MHz

System Performance: User Define

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): 6T

K, I'm currently in windows with those settings....but that's underclocking all 3 of my sticks of RAM. I did run memtest and got 0 errors, but i didnt try with higher settings yet. I did try and up the voltage to 2.8 and I still can't get windows to even begin booting with 400 mhz, whether i have 2.5t or 2t for the cas latency.

This is a chipset limitation.

If the FSB of your CPU is 400 For Intel and 100 MHz for AMD, the memory speed supports only DDR 266.

If the FSB of your CPU is 533 For Intel and 133/166 MHz for AMD, the memory speed supports DDR 266/333

If the FSB of your CPU is 800 MHz for Intel and 200 MHz for AMD, the memory speed supports DDR 333/400

Um...how? My Golden Dragon has been running at 400 mhz steady at 5-3-3-2 for 2 years now. My friend has the same mobo and a piece of corsair xms at 400 mhz that is running at 5-2-3-2 just fine for a year now. I think it's something wrong with the stick.

My golden dragon is perfect, not a problem with them, the problem is with the corsair stick, i ran it in my friend's AMD 3200+ (400 mhz fsb) and it wouldn't even post. The only way i can get the corsair stick to run atm is with underclocked timings and speed. I tried keeping the 166 x 12.5 multiplier (i had 11 x 200 with my golden dragon) which is stock for the processor and setting the memory frequency at 120% giving it a 400 mhz clock and the thing still couldn't make it to the windows loading screen

I would suggest you run a memory bench mark on both settings and I think you will find when the memory is in sync you get much better performance even though it’s running at DDR333. I would try Everest 1.5.

But with my golden dragon (and i should've been able to do with this) i was able to put my processor at 200 mhz, so it was in sync anyways. Plus, the stick is advertised as 6-3-3-2, and i can't get it to run unless it's 6-3-3-2.5

Okay, that explains the cas timing, but not the clock speed. And here is a link for the Newegg website of which I bought the RAM. Ram The advertised speeds are 2-3-3-6 and when i talked to the customer service rep for Newegg.com he said that all the info they get is from you. So your company failed to tell me that because I have AMD my RAM would be a little bit slower. I don't think that's something I should have to pay for. I paid for 2-3-3-6 400mhz PC3200, not 2.5-3-3-6 333mhz PC2700.

I am sorry you would need to take that up with Newegg. And all of our modules are listed in XMS Qualification and Testing by part# and the make and model of MB we use along with the tested settings. And as I have said running at DDR400 would require you to have a 200 FSB CPU. If you are over clocking the CPU and getting errors that may be the CPU not the memory causing the problem, but I would need to know more detailed info to try and help you with that. In addition, I have no problem replacing your modules, but based on what you have posted that may not solve the problem.
