Some time ago I bought a new computer: AMD Phenom II X4 955, Geil DDR3 4GB PC1333 Value Series CL9, MSI 770-G45, ZOTAC GeForce GTX470 AMP, BeQuiet PurePower L7 530W.
Unfortunately, since the first use I have been dealing with some problems: blue screens, installation errors and above all CRC Errors with every downloaded large (~300MB) .RAR file. I've done many tests to find out what's wrong. For sure it's not software issue: OS is new with newest drivers etc.
So I tested my memory (with Memtest86+ among others) and it is 100% OK. HDD is 100% OK. Then I tried Prime95 - and after just a few seconds it showed "Hardware Failure Detected". But the error appeared only when I was doing "Blend" tests (lots of RAM tested), but not with "Small FTTs" tests (lots of CPU tested). I borrowed memory (Patriot DDR3 2x2048MB Viper Series 1600MHz CL 7.0) from my friend and I found out that it works perfect on my computer - no CRC Errors nor Prime95 error. But memtest showed my memory is fine too - so just to make sure it really is, I went back to the shop and replaced it with new modules (of the same Geil model), but it changed nothing.
Then I started some fun with BIOS - I set NB to 2200 MHz and memory voltage to 1,67 V. And Prime95 doesn't show any errors any more; BSODs also don't appear. But still I've got the problem with CRC Errors and I have no idea how to deal with it. Let's some up: 1)My memory is fine. 2) With Patriot memory mentioned above, the problem is solved. 3) So I assume the only way to solve the problem with my Geil memory is to go on with some changes in BIOS. Maybe I should deal with timings? Or with CPU-NB voltage? Could you guys give me some detailed instrucions what values should I try, or maybe you've got other ideas? I must add that I tried to slow the memory down to 1033MHz and 800 MHz but it didn't help. I also updated BIOS.
THX in advance!!
