complete specs
cpu: intel Q9450 stock cooling
mobo: asus P5Q-E
memory: kingston hyperx (KHX8500D2K2/2G) 2.2v DDR2 1066MHz Non-ECC CL5 (4GB total)
graphics card: asus 8500GS
hard drive: 1x 80GB os drive fresh install of xp 3x 1TB storage drives
PSU: 500w coolmax

im using a ASUS P5Q-E mobo and im running memtest using kingston hyperx memory.

i had 4 sticks in each stick is 1gb and i would get errors after 20 seconds.

so i ran memtest over night with just 2 sticks in and i didnt get an error until pass 13.

so i took 2 sticks of crucial and put them in and i got an error in pass 2.

now im using one stick of the kingston and i ran 4 passes with no errors and i moved the ram to the next slot and am running the test.

have i just got a ton of bad ram or could the mother board be bad? should i continue testing one slot at a time then test each stick of ram?

what are your suggestions.

see post 3 for what im currently testing

here is some more info.
kingston hyperx (KHX8500D2K2/2G) 2.2v

memtest says the timing is 5-5-5-18


kingston.com says it is - 2GB kit DDR2 1066MHz Non-ECC CL5
(kit of 2 - 1GB) - 5-5-5-15

DRAM voltage is set for auto in BIOS standard is 1.8V

NB voltage is set for auto in BIOS standard is 1.10V

still having a problem with prime 95 im using the blended test.

error: rounding was 0.5 expected less then 0.4. hardware failure detected.

it starts with the logical core #2 every time. and i get the error in the first test.

then the logical core #3 gets the same error. it does that in the 4th test.

im running test #() 4,000 L-L iterations of M19374367 using FFT length 1024K

also keep in mind this system is all stock still except for the dram voltage is 2.2V and the NB voltage is 1.2V
also im using a Q9450


the answer

4 sticks with a dram voltage set to 2.0v, and NB set to 1.2V, CPU voltage 1.25v (updated bios and drivers)

RMA the sticks, it's most likely bad ram sticks. You shouldn't get any errors when running memtest for the ram to be okay, even one error is one to many.

Test each stick by it self and you should know whitch one are bad and whitch one that works fine. RMA the bad sticks.

4 kingston sticks in 4 slots- errors in 1st pass
2 kingston sticks in in slots a1,b1- errors on pass 13
2 crucial sticks in slots a1,b1- errors on pass 2
2 crucial sticks in slots b1,b2- errors in 1st pass

same stick for each test
1 kingston, stick (1) in slot a1- no errors after 4 passes
1 kingston, stick (1) in slot b2- errors in 1st pass
1 kingston, stick (1) in slot a2- no errors after 4 passes

1 kingston, stick (2) in slot a1- no errors after 4 passes

4 sticks with a dram voltage set to 2.0V, and NB set to 1.2V 1 pass no errors - prime 95 it errors after 2 minutes
4 sticks with a dram voltage set to 2.16V, and NB set to 1.2V prime 95 it errors after 2 minutes

4 sticks with a dram voltage set to 2.2v, and NB set to 1.2V no errors after 23 passes - ram is good - prime 95 errors in first test on #2 core and 4th test on #3 core.

prime 95 errors after 2 minutes.

4 sticks with a dram voltage set to 2.2v, and NB set to 1.24V, CPU voltage 1.25v other settings same - prime 95 errors after 2 minutes.
4 sticks with a dram voltage set to 2.2v, and NB set to 1.24V, CPU voltage 1.25v set memory frequency and timings back to auto - prime 95 errors after 2 minutes.
4 sticks with a dram voltage set to 2.2v, and NB set to 1.24V, CPU voltage 1.25v set everything else back to auto - prime 95 errors after 14 minutes.
4 sticks with a dram voltage set to 2.2v, and NB set to 1.24V, CPU voltage 1.3v - prime 95 errors after 49 minutes
4 sticks with a dram voltage set to 2.2v, and NB set to 1.24V, CPU voltage 1.3v Set DRAM frequency manually to 1066
Set timings manually: 5-5-5-15 - prime 95 errors after 10 minutes
4 sticks with a dram voltage set to 2.2v, and NB set to 1.24V, CPU voltage 1.3v Set DRAM frequency manually to 1066 - prime 95 errors after 5 minutes
4 sticks with a dram voltage set to 2.2v, and NB set to 1.24V, CPU voltage 1.3v Set timings manually: 5-5-5-15 - prime 95 errors after 5 minutes

4 sticks with a dram voltage set to 2.2v, and NB set to 1.24V, CPU voltage 1.3v (updated bios)- prime 95 ran all night no errors
4 sticks with a dram voltage set to auto, and NB set to auto, CPU voltage auto (updated bios)- prime 95 errors in 2 minutes
4 sticks with a dram voltage set to 2.0v, and NB set to 1.2V, CPU voltage 1.25v (updated bios)- ran 7 hours no errors.

currently testing

4 sticks with a dram voltage set to 2.0v, and NB set to 1.2V, CPU voltage 1.25v (updated bios) testing over night with the lower voltages.

What are you voltages and timings? That has a major impact.

To run 4 sticks you need a higher MCH/NB voltage.

i will check that when i am able to. im not O.C.ing the system so every thing is stock just to give you all that info too.

1 kingston stick in slot a2- no errors after 4 passes

i edited the above post with this info too.

i finished testing all 4 slots with the same stick of ram.
1 kingston, stick (1) in slot b1- no errors after 4 passes

i am now starting over with the second stick of ram.

here is some more info.
kingston hyperx (KHX8500D2K2/2G) 2.2v

memtest says the timing is 5-5-5-18


kingston.com says it is - 2GB kit DDR2 1066MHz Non-ECC CL5
(kit of 2 - 1GB) - 5-5-5-15

DRAM voltage is set for auto in BIOS standard is 1.8V so is that the current setting?

NB voltage is set for auto in BIOS standard is 1.10V

what is MCH?

No wonder they give errors at 1.8v, the sticks are rated for 2.2 (at overclock). They will probably run just fine at 2.15v when running stock.

When using 4 sticks, set your NB to 1.2v. And when using 2 sticks, the default option is ok.

I don't have the same board as you but I had a problem very similar to this on my p5n32e board. In the end I just got fed up and ran the board without a dual channel configuration.

I tried to run with just one stick and it failed then I tried two sticks, still failed. After doing every type of combo I went for a configuration that didn't allow for dual channel but it worked.

ok so you think that the sticks are under powered and that is what is causing this issue.

i think i will try all 4 sticks again and start with dram at 2.00v and NB at 1.2v then run memtest. how does that sound?

but why did the ram fail in the 4th slot and pass in the other 3?

here is what i have done now.

4 sticks with a dram voltage set to 2.0V, and NB set to 1.2V 1 pass with memtest no errors - prime 95 it errors after 2 minutes
4 sticks with a dram voltage set to 2.16V, and NB set to 1.2V prime 95 it errors after 2 minutes

im now testing all 4 sticks with memtest and will probably let it run through the night.

is there a chance im running prime 95 wrong. im using the blend test so that it will work the processor and the ram. it runs 4 tests at a time default because it is a quad core cpu.

If you are using 4 sticks, raise the DRAM voltage to 2.2v just to be sure. Are you mixing the Kingston and Crucial sticks?

no it is 4 kingston the crucial was when i thought i had 4 bad sticks of ram so i wanted to try different ram.

am i risking blowing my ram up at 2.2v and what about over heating. this will be running 24/7/365

No, because the manufacturer rated them for that voltage.

They would shoot themselves in the foot if they didn't work at that voltage.

well i let memtest run all night. and it made 23 passes with no errors so im guessing my ram is good. i might lower the voltage down a little and let it run all night again.

but im still having a problem with prime 95 im using the blended test.

error: rounding was 0.5 expected less then 0.4. hardware failure detected.

it starts with the logical core #2 every time. and i get the error in the first test.

then the logical core #3 gets the same error. it does that in the 4th test.

also keep in mind this system is all stock still except for the dram voltage is 2.2V and the NB voltage is 1.2V
also im using a Q9450

If memtest passes 23 times without errors, then the problem surely lies somewhere else. Try NB voltage 1.24v because you are using 4 sticks.

what does upping the NB voltage do for the system. just curios because i want to learn what it is im doing to the system.

The NB is the northbridge. The northbridge controls a lot of traffic between components such as the memory.

Here's a wiki page:

ran prime 95 for 14 minutes before i got an error so bumping up the NB voltage helped.

i have bumped it from 1.24 to 1.26 now.

Yeah then that seems to be the problem. You might need to set it up to 1.3v. Do you have any other DRAM settings that are still at "auto"?
