No problem.

A CPU socket issue can cause several different problems including memtest86+.
If you take the CPU out to check it, make sure you check the pins on the motherboard socket, use a magnifying glass and look for any bent pins.

I did pull out the whole motherboard yesterday, checked all pins on the CPU and they where fine.

What pins you mean on the motherboard socket? Do you mean the "holes" on the socket where one is supposed to fit in the CPU?

BTW, didn't see any damaged capacitor or any other visible damaged component on it.
Also, i did let Memtest run overnight again with both Ram Sticks in, and got 19 errors, one failing address:
0018439a004-6211.6MB
Which is the very same failing address that i got when running Memtest the first time with both Rams in. The only difference is the Good/Bad/ErrBits. Also, i always get this error in Test 6 or 7. The first time both Rams in, was Test 7, now the second time both Rams in it's Test 6. Ram#1 had the failing address 2 times in Test 7, and Ram#2 had the failing address two times in Test 6.

I will go now, and get me a new Mainboard and Ram. At the same time, i will build out my PSU, and i hope they have a PSU-Tester there.

Will post my further tests once i get to them. First one will be probably new Ram in old Mainboard.

Ok, the PSU is working fine, that at least told me the guy from Fry's, and that knowledge cost me 14$ ~.~" In Europe such a thing was for free, as the shop knew I'm a good customer.

Anyway, i will today's night, proceed to run Memtest with the brand new Ram. It's supposed to be the same one, but if i am not mistaken the back tells me it's "ver8.16", i belief the old one is ver7.something. Well i see tomorrow what Memtest think's of those two Sticks.

Post the CPUZ Memory and SPD tabs for the new RAM.

For AMD the pins are on the CPU.

Hi Dave76,

I let run Memtest86+ for 20:30 hours, 10 full Pass and the 11th was at test 8 or so. Error free. So it was the Ram, that just got damaged, or broke. The PSU is fine as is the rest (CPU, Graphic Card and HD's) as i tested through several Tests.

It it indeed the very same Ram as the old one, the only difference is the old Ram has ver2.12 on the back, and the new as i said ver8.16.

I attached the CPUZ for Memory, Slot#1 SPD and Slot#2 SPD.

The Ram is supposed to run with 1.50 volts, the Bios tells me that "DRam" is set at Auto = 1.50 volts. The CPUZ shows 1.50 volts also.
BTW, the "Channels" in CPUZ says "Dual", does that mean my ram runs in Dual Mode?
Also, one more thing. The Ram states 1333MHz, 9-9-9-24, whereas in Memtest i only see CAS 4-5-5-15 DDR1334. On my wife's PC, Memtest shows on the bottom the Ram Stats, Corsair also (DDR2), but for me i not see the Ram Stats on the bottom. Is it because i have more then 4Gig ram?

The RAM voltages in CPUZ/SPD are recommended not actual, which is why you need to check the voltages in your BIOS.
SPD tab is reading a file put on the RAM cards by the manufacturer, these are the recommended, tested, settings.
Only the CPUZ/CPU tab shows the actual CPU voltage.

Your RAM is in Dual channel mode, which is what you want it to be. With four RAM slots there are two slots per channel, with one RAM card in one slot in each of the two channels will give you the best performance, Dual channel.

It will depend on the RAM cards, I've seen that mis-information before and it doesn't seem to cause any bad effects.

Glad you got the system stable, congrats.
You can mark the thread 'Solved'.

Well, i not know if my system is Stable now, but since i checked the CPU, Video-card, HDs, PSU there is only one thing in there i didn't check : the Mainboard. But that seems to work, as the Memtest86+ with the new Ram proven.

Just to clear up the information. Where in the bios do i need to check for the Ram Voltage? I know it's on this bios in the Cell Menu, but is it CPU VDD Voltage, CPU-NB VDD Voltage or DRam Voltage? The DRam Voltage stands on Auto, which means 1.50Volts, and i read for AMD the Ram Controler is with the CPU.

Is it possible that the Ram got damaged by too low/high Voltage Settings?

Maybe the UEFI Bios on the New Mainboard is clearer in the presentation in this ^^.

Checking motherboards for defects is difficult, you have to check everything else, if everything checks out ok, that leaves the motherboard.
Note: sometimes you need to check your components in another computer to verify.

For the 'DRAM voltage' (this is the RAM voltage) and RAM controller which is (integrated in the CPU) called the IMC (Integrated Memory Controller) on your motherboard it's called 'CPU-NB Voltage', see post #44.
You may need to select 'Manual' and increase the voltage by a small amount to see the actual voltage number.

Damage to RAM can be from too high voltage, not from too low voltage, but they do wear out after some time from no real cause besides normal use.

The new UEFI motherboards have the basic same settings as the older motherboards, just the user interface looks different.
The DRAM and IMC will probably have different names in the new motherboard, all the manufacturers seem to change the name on a regular basis, even the same company changes the name with almost every release.

Well i didn't check the old Ram in a different PC, but i think it's enough, that the old Ram produces Errors(and always same addresses) and the new ram in the same system don't.
I am unsure did i get a power surge, or not as the problem arose very strangely sudden. But if i got one, the only other component that i could not check via tests was the Mainboard, so i'm gonna let the new Ram run some time in the Old Mainboard.

So that means in case i kick 16GB on the Mainboard, i need to increase the voltage towards the Northbridge also.

Anyway, i gave everyone rep that helped me in this thread, including you. Maybe you see it?

You can send me private messages also right? Then i close this Thread, i open another one if i get trouble again.

Yes, I replied on your profile page.

Did you get a surge protector?

You won't see any performance increase by going from 8GB RAM to 16GB.
Don't need that much RAM unless you are going to run Virtual Machines or graphics rendering, etc.

You have to be very careful when increasing voltage on RAM and especially the IMC (CPU-NB Voltage), too much will damage the RAM and CPU.

If you want a big performance upgrade consider getting a SSD.
Put you OS and programs on the SSD and all you personal data on the HDD (Hard Drive).
