OCZ FlexXLC PC9200 - spontaneously dying?

JorisS · 12-22-2007, 01:37 AM

Hi all,

recently bought 4 x 1Gb of the memory as per topic title, OCZ FlexXLC PC9200. Bought them second hand and according to seller in 100% working order, tested with memtest. Installed them here at my place and things went fine although I had some strange errors with winrar, as well as crc errors in downloaded files, occasionally. After a while I started wondering about this and downloaded memtest and checked the memory. Turned out one of the sticks generated MASSIVE errors, i.e. screen filling up with red in no time, and errors stacking up rapidly. An RMA is currently being processed for the memory pair of which this was one.

From that point I continued with the other 2 pairs, which didn't show any problems in memtest. Recently, however, I started getting new strange and random error messages, program failures etc. So just put the memory to the test again and now one of the other sticks is generating MASSIVE with failures.

What's going on?

I've read that the memory in question requires 2.3V to operate properly - initially I was running everything in AUTO and things worked (so I'm not sure if AUTO actually put the voltage to 2.3V, as indicated in the memory SPD? or not. If not, it's quite amazing the system worked as it did at 1.8V i think?). After the failure of the first stick and contact with the seller I put the BIOS settings to +0.5V, counting from the standard 1.8V. Been using it as such since, until the recent problems.

I might add that all the above spans about 1.5 week, and I have swapped a GFX in the process - so theoretically I guess there could've been a problem with statics or such. Quite odd though, never had any such problems before.

So now I have 2 defective sticks and 2 working ones. I'll send the 2 defective sticks on RMA (or is that a bad idea, as they originally weren't of the same pair?) - but I want to try and figure out what is killing the sticks, so I keep the 2 remaining ones in proper shape!

I'm running the following system:

GA-P35-DQ6
Intel C2D E6600
2 Gb OCZ FlexXLC PC9200
Asus X1950XTX
3x HD S-ATA
1x DVD-ROM
Fortron SP 700W PSU
Aquaduct XT 360 external water cooling

I'm currently not watercooling the memory, but there's a big 120mm fan blowing in cool air from the side and the memory doesn't even warm up the slightest. Running everything in AUTO/default in the bios, no clocking whatsoever.

Please help, this is silly!
Are these memory sticks so darn sensitive or am I systematically killing them off by 'underpowering' or so? Should I pick manual settings for CPU multiplier and FSB and adjust memory ratio?

Best regards,
Joris

2.3v

Thanks.

I was running +0.5V (on Gigabyte board this means 1.8V + 0.5V = 2.3V, if I'm not mistaken?) with the pair of 2x 1Gb though, then 1 broke down for some reason.
