sirugo Posted October 22, 2005 Share Posted October 22, 2005 Almost one year ago I bought a pair of VS512MB400 for my Apple G5 dual 1.8 GHz. they worked fine until about two weeks ago when strange things happened. I thought I had disk problems so I reformatted everything, zapped PRAM and installed system and apps from scratch. Still I had the same problems as before I decided to reinstall: applications crashed almost immediately after a while without any obvious reason. Never happened before. I realized i had to do a memory test so i ran Techtool (4.0.5) and it failed the test (-2) many times. Then I also an memtest and it failed almost every subtest. I removed the pair of Corsair modules and everything worked fine for days. I remounted the pair and the problems returned immediately. Is this good enough as a proof of bad modules or is there anything else I must do before aiming at the lifetime warranty. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 24, 2005 Corsair Employees Share Posted October 24, 2005 Please test the modules one at a time with memtest or some equivilent for MAC and you cannot mix Value Select with the memory that came with your system.

sirugo Posted October 25, 2005 Author Share Posted October 25, 2005 But they have worked fine for one year! No problems at all. And everyone has adviced me to choose these sticks together with my system. Even one of Sweden's largest retailer of Apple products has tested them and recommend them. Many others do as well. I have now tested my G5 with ONLY these sticks (Apple originals removed). First I didn't get the errors with memtest. I launched a few applications and most of them crashed on startup as they have not been doing for a week with the oroginal modules. So I did another memtest and WOW - all these errors are there again. Here's about one percent of the output given by memtest: Test sequence 1: Stuck Address : testing 0FAILURE: possible bad address line at offset 0x09a3c25b. Skipping to next test... Random Value : FAILURE: 0x77fd32d1 != 0x77ff32d1 at offset 0x04bd229b. FAILURE: 0xb3984a8a != 0xb39a4a8a at offset 0x04bd230b. FAILURE: 0x7f7c9b2a != 0x7f7e9b2a at offset 0x04bd231b.

My G5 requires modules set in pairs to boot at all. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 25, 2005 Corsair Employees Share Posted October 25, 2005 We can try replacing them if you like, but we would normally suggest our System Select for any OEM system for best compatibality.

sirugo Posted October 27, 2005 Author Share Posted October 27, 2005 Well over 24 hours have passed. Still no RMA # in my mailbox. Also: I don't think Systen Select existed as a Corsair product when I ordered Value Select last October. Link to comment Share on other sites More sharing options...

sirugo Posted October 30, 2005 Author Share Posted October 30, 2005 I have now filled out the online form and submitted it. After 48 hours I was told also to fill out the Excel-form (for RMA#) and send it via e-mail. I did that. No RMA! I really need my RAM. Link to comment Share on other sites More sharing options...
