I have 2x512 Mushkin XP4000 memory and a dfi ultra NF4 D woth a venice 3200, now i am having major and strange problems with my memory.

Stick one

Won't pass mem test at ddr400 in the top yellow slot, it will trhow up errors in seconds @2.8v, it is now however running at [email protected] for 5 mins and counting without any errors. Edit it is now showing errors after 50 mins, putting all back to stock and trying this stick again.

Stick two

Wont pass mem test at any speed in the top 3 slots, took it round to a friends it ran in his machine for 10 passes of mem test without problem @2.8v DDR400

Whats going on?

What test produces the errors?
What BIOS version are you using?

At the minute i am ignoring mem test, it is passing prime at 260mhz for 7 hours (without failing) runnig pi fine, running 3d mark fine and also playing games fine.

I suspect it is a problem with mem test rather than the ram. :confused:

Matty can it do 8+ hours of Prime95 Blend test (uses lots of memory)?


Have you tweaked any of the memory settings in the BIOS and also can you post an A64Tweaker screenshot of your overclocked setup please mate so I can see what settings you're using.

I ran the blend test for 7 hours yesterday and it passed fine, i will post a pic with A64 tweaker tomorrow when i am next on my rig. :)

An error in one of the first four tests means it is VCore or CPU FSB related, not memory related.

What you can do if you do't trust Memtest86+ is to run Prime95's Small FFT test as that stresses the CPU

Well i ran mem test at default settings ie stock straight from the box, and it still failed straight away, but the other stick passed at 3.4v with the ram @ 265mhz and the cpu at 2650mhz.

If there was a problem with the cpu would it pass the blend test for 7 hours, amd also pass pi and 3d mark without even a slight hiccup? :)

But the bottom line is that if you are happy with the stability of your machine it's fine, the only time you would want (need) a fully stable machine is if you do Distributed Computing.

I agree with you whole heartedly there, i mean there are people who will say it is not stable blah blah, but it is not used for distributed computing or anything else important. I have a laptop for general web surfing and a file server for storage, my desktop is only used for a few (2-4) hours at a time maybe a couple of times a week for when i need something more powerful for a task or to play a game on.

If the machine starts playnig funny buggers and crashing and blue screen of deathing, then yes of course i will look into it further to see what the problem is, but if it can run for the length of time i need it for without glitch how can i say it is not stable, because for me it is. :)

I will at some point run the test you suggested and see what the results are Dutch Guy, and thank you for your help, in a side note would sis soft sandra burn in test (cpu and memory tests only) be a good check for faults, as i thought that would really stress a system?

Thanks again.

I have no experience with that, perhaps that only heats up the CPU when Prime95 checks the calculations it is doing and reports it if it finds an error.

I think the burn in test keeps running the cpu and memory tests from sandra (or whatever tests you chose) and runs them on cycle over and over again. :)

Small fft's at priority 10. :)
 
I had my Mushkin running at this speed before but wasnt very stable (i think it was the cpu)

So yeah with some good memory, if your cpu can handle, it will fly.
