A few days ago I bought a pair of Geil Ultra-X 2-2-2-5-1T (2x512MB in DC).
I installed them and the system boot without any problems.
Selecting optimized defaults in system bios, the memories recognized as 2-2-2-5-2T,
and read preamble value as 6ns instead of the 5 that the IC's support. At this point I want to say that in the beginning I didn't know what was the type of the IC's. Where they TCCD or BH-5;
So I set CL at 3 in system bios and the system couldn't boot, so I suppose I'm having
the Windbond BH-5 IC's.
After that I entered system bios and made some modifications:
I set manually command rate at 1T and read preamble value at 5ns.
I reboot and everything went fine.
After a time period at boot time I saw a message I should disable the overclocking features for system stability. Quite weird as the rams work at their
specifications 2-2-2-5-1T, 2.7v, read preable value at 5ns.
So I loaded again optimized defaults in system bios and ran a blend test in
prime 95.
After 1 hour and 14 minutes I saw the following message in prime 95:
"FATAL ERROR: Rounding was 0.49609375, expected less than 0.4
Hardware failure detected, consult stress.txt file".
Then I ran memtest86 v3.2 for 7 hours and 30 minutes without reporting any memory errors.
I did also some separate tests with test 5, test 6, and test 7 each of them for over
an hour, and again no errors were reported.
These tests are supposed to be very stressful.
Strange because memtest didn't report any errors instead of prime 95.
Could it be a compatibility issue between M/B and rams?
Till now I didn't have any issues in any applications, even at hard gaming where everything is at full load, video processing etc.
No crashes no problems at all.
So to sum up:
Is it a problem between the M/B and memories? I mean can this M/B drive these rams correctly?
Should I go for a DFI LanParty?
Could it be a bug of the prime 95? I ran it again for a second time and I got the above message again after 3 and a half hours.
Cpu is not overheated in any way.
What appication should I trust?
Memtest or prime 95?
I repeat that I don't have any problems with my rig.
I would appreciate any help.
