Memtest is only using one core.

Certainly not a good batch of RAM. From your earlier note >300 errors is a very large number, especially very early in the life of a chip. The reason for trying three passes is to see if there are any thermal issues, a fail on pass one is a bad fail, and could explain some of the issues you are having with booting from cold.

ops I need better glasses didn't read the screen shot properly thank rob for pointing that one out silly me

Actually for part of the tests it does use all 4 cores , and then for part of them it just uses 1 core... I kinda figured it knew what it was doing...
It should have been designed with multi cores in mind... !

Individual Test Descriptions

MemTest86 executes a series of numbered test sections to check for errors. These test sections consist of a combination of test algorithm, data pattern and cache setting. The execution order for these tests were arranged so that errors will be detected as rapidly as possible. A description of each of the test sections follows:

Test 0 [Address test, walking ones, no cache]

Tests all address bits in all memory banks by using a walking ones address pattern.
Test 1 [Address test, own address, Sequential]

Each address is written with its own address and then is checked for consistency. In theory previous tests should have caught any memory addressing problems. This test should catch any addressing errors that somehow were not previously detected. This test is done sequentially with each available CPU.
Test 2 [Address test, own address, Parallel]

Same as test 1 but the testing is done in parallel using all CPUs and using overlapping addresses.
Test 3 [Moving inversions, ones&zeros, Parallel]

This test uses the moving inversions algorithm with patterns of all ones and zeros. Cache is enabled even though it interferes to some degree with the test algorithm. With cache enabled this test does not take long and should quickly find all "hard" errors and some more subtle errors. This is done in parallel using all CPUs.
Test 4 [Moving inversions, 8 bit pattern]

This is the same as test 3 but uses a 8 bit wide pattern of "walking" ones and zeros. This test will better detect subtle errors in "wide" memory chips.
Test 5 [Moving inversions, random pattern]

Test 5 uses the same algorithm as test 4 but the data pattern is a random number and it's complement. This test is particularly effective in finding difficult to detect data sensitive errors. The random number sequence is different with each pass so multiple passes increase effectiveness.
Test 6 [Block move, 64 moves]

This test stresses memory by using block move (movsl) instructions and is based on Robert Redelmeier's burnBX test. Memory is initialized with shifting patterns that are inverted every 8 bytes. Then 4mb blocks of memory are moved around using the movsl instruction. After the moves are completed the data patterns are checked. Because the data is checked only after the memory moves are completed it is not possible to know where the error occurred. The addresses reported are only for where the bad pattern was found. Since the moves are constrained to a 8mb segment of memory the failing address will always be less than 8mb away from the reported address. Errors from this test are not used to calculate BadRAM patterns.
Test 7 [Moving inversions, 32 bit pattern]

This is a variation of the moving inversions algorithm that shifts the data pattern left one bit for each successive address. The starting bit position is shifted left for each pass. To use all possible data patterns 32 passes are required. This test is quite effective at detecting data sensitive errors but the execution time is long.
Test 8 [Random number sequence]

This test writes a series of random numbers into memory. By resetting the seed for the random number the same sequence of number can be created for a reference. The initial pattern is checked and then complemented and checked again on the next pass. However, unlike the moving inversions test writing and checking can only be done in the forward direction.
Test 9 [Modulo 20, Random pattern]

Using the Modulo-X algorithm should uncover errors that are not detected by moving inversions due to cache and buffering interference with the algorithm.
Test 10 [Bit fade test, 2 patterns]

The bit fade test initializes all of memory with a pattern and then sleeps for a few minutes. Then memory is examined to see if any memory bits have changed. All ones and all zero patterns are used.

So all your sticks are bad then ?
Let's hope they don't make you wait to long to replace them and refund your money.
Now you can relax a bit and not throw it out the window lololol

If they were My sticks I'd return them and get some G.Skill ram, I have two Asus motherboards, one lists G.Skill Ripjaws X DDR3 1333 ram(P7P55D Pro) and the other doesn't(a Rampage 3 Extreme), both run just fine with G.Skill, I looked in the thread and I couldn't find any mention of what Asus motherboard that you have Floyd(I'm not doubting you either), outside of the vague thread title that says 'ASUS MB Owners'...

Mind you Floyd since I don't know what ram beyond Corsair that you use, I can only mention what I've seen and know. Some ram operates as low as 1.25v and the motherboard needs to support this or the ram will have to accept a higher voltage, otherwise they'd be incompatible with each other. I could only find 2 lists, one at 1333 and the other at 1600.

From the list there, I found these two, one of which is what I use(2x4MB 1333):

I am curious about something , WHY , would legacy usb support have to be disabled , and the time driver be set to 2T , on this MB for this Ram to check out with NO errors ?
I just talked with Tech support again and he said to re-test with the conditions listed above.
Sure enough... The ram tested on 1st pass this time as good.
When I tested the OLD ram , I didn't disable anything and the timing was still set at 1T , It passed the test with 9 passes NO Errors. ?????

What is the difference?

---

Ok I run My timing at 9-9-9-24 and the voltage is at about 1.58v(It's been a while since I looked), but then I have 16GB of G.Skill Ripjaws X (2-G.SKILL F3-10666CL9D-8GBXL 8GB kits) installed and I can't go beyond 1.65v cause of the cpu being an Intel and having a limit of 1.65v to protect the cpu, not that I couldn't go beyond that in the bios, but I'd rather not. Oh and the ram is set at 2T, instead of the more aggressive 1T. I think I put one kit in one set of dimms slots and the other on the last pair of slots.

Well I don't know about the usb, since I'm all usb 2.0 here, even My R3E only has a few usb 3.0 ports, as to 2T vs 1T, 1T is aggressive and tighter, 2T is looser and generally works better, especially for overclocking ones ram, if one does that.

Yes , But the problems started before I put the GT 430 in the PC...

The thing is that that PSU has 2x 18amp 12v rails and if I remember rightly a GTX460 requires about 20-22amps (depending on the model) so you possibly have at least 1 of those rails over its maximum limit under full steam. Now the other rail with that processor would be getting pretty close as well and fitting that GT430 would be adding that much more load to it again.

Now even if that PSU can revert to single rail operation when 1 rail is overloaded, which I can't say that it can but even if it could the total output wouldn't be over 40amps, more likely around 38-39amps.

I've seen some strange behaviour from systems that are under powered and yours certainly fits the bill. Personally I would've gone with a PSU that will deliver at least 45amps on a single 12v rail (50amps would be better again).

Cheers.

Not shore if this will answer your post Floyd but give it a look . It does say something about command rate timing and something about 4x memory modules

Yeah that is cutting it close and could be the source of the problems, not enough power.
