ripeto, nulla toglie che uno o entrambi i moduli possano avere un qualche problema: in ogni caso li dovrai rispedire entrambi in RMA, quindi non fa alcuna differenza.
Detto questo esistono delle versioni di MemTest86+ (hai indicato la v4.20), nel particolare quelle basate su una distro Ubuntu, che presentano proprio dei problemi (apparenti) al test 6 e 7.
codice:
Test 6 [Moving inversions, random pattern]Test 6 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 7 [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.
Quello che mi fa venire dei dubbi è il fatto che non esistano assolutamente errori al test 8:
codice:
Test 8 [Moving inversions, 32 bit pat]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.
A questo proposito, proprio per approfondire le prove del caso, esiste attualmente la v5.00beta1 di MemTest86+, scaricabile da QUI, che sembrerebbe non indurre problematiche analoghe.
Prima di inviare le Vengeance in RMA (e dovertene quindi privare per diverse settimane), provarla non sarebbe male.
