RAM Performance loss (OCZ REV PLAT 2)

Recommended Posts

Has anyone ever heard of this happening?

 

I have OCZ Platinum El Rev 2 Sticks, 2 x 512.

 

I had my system at the settings in my sig and it was running fine for over 3 months. I then reduced my clock speed to 2.4ghz in order to lower my volts for longevity. Well this week I have been playing WOW and crashing a lot. So I initially ran Prime95 and found my system to be unstable. I have been gradually lowering my OC and the crashing has been increasing.

 

Today was the last straw. It wouldn't even boot.

 

So...

 

I started running diagnostics on my hardware. When I got to my RAM I found the culprit. I ran memtest and now my sticks will not pass test #5 unless I raised my DRAM voltage to 2.9 and I have the FSB at 240 or lower. I noticed when I have the sticks around the max they will take, they would error out at 95% pass or so. This was consistent.

 

Does anyone have an explanation for this? I have a hunch that my sticks are going south, but I thought I would check here before I bother Ryder or Andy.

 

Thanks everyone.

Try running 2,3,3,7 timings at 240 or so and see what happens. I have the same ram and after sometime they won't boot at 2.5cas but 2.0 cas will run fine up to 255-260.

 

Give it a shot and see what happens.

I tried your adjustment and it did help some. However, I am still interested in the fact that this crapped out after 6 months. Does anyone have any isight on this? My system was OC Database stable until now. (I have a 23 hr Prime screenie to prove it.)

 

Thank you everyone.

Ya know how it is when overclocking your running on the edge. It may be ram and maybe cpu sometimes hard to tell with out other ram or cpus laying around.

What kind of voltage are you running to the memory and also what WHERE you running before voltage wise?

I would update the bios also, to the 5/10-2. I'm sure thats not the problem but it might help some the 3/10 bios was not good at all for my system.

What's wrong with the current 623-3 or the common 704-2bta? Why recommending an old bios?

I was running the RAM at 2.8v. The system was running at 260 * 10 (1.55v) with timings of 2.5-4-3-8. Lately it has been running at 2.8v with the FSB at 240 * 10 at 1.44v.

 

Now in order to be stable I am running at 245 * 10 on a 3/4 Divider. Also the RAM needs 2.9v to stay stable.

 

I will update the BIOS as soon as I buy a new floppy drive. Those damn things burn out way too easily on me for some reason.

 

The biggest mystery to me is why this would happen out of the blue? I haven't been pushing my system to the edge. I was only running a fairly modest OC to narrow the risks olf something like this happening.

Why? I just recommended the 5/10 cuase it works very well with my set up which is simular to his. The 6/23 is also a good bios but the 704 wasn't to good for me really. There's not alot of difference from each bios really but the 5/10 just gave me more stabity at higher clocks then the others.

Thats the joy of electrical parts, they either quit working or degrade in performance. It sounds to me like the beginning of the memory taking a crap to me. There's a few threads around about TCCD getting to much voltage and them degrading performance wise or worse yet losing CAS 2.5 which has happened to me already.

How do they do with 2.9v's at CAS 2.0? Just for the hell of it try 245x10 with 2,3,3,7 with 2.9v's 1:1 Also what are your other timings set at?

Yup same here it will not do anything other than cas 2 every bios in the book and many many diffrent setting. Previously it would overclock to 270-300 FSB 1:1 with a lower CPU multi. I think it started doing this about 5-6 months after I got it and I bought it a year ago. It is not all that uncommon for TCCD I hear after a wile.

I seem to recall reading that the SPD gets corrupted after prolonged use of high voltage, causing the loss of the 2.5 CAS. Now this would normally require an RMA, but just recently someone has developed a way to revive dead BH5 through rewriting the SPD. I would suggest checking out this thread at XS. I do not know if it will work for TCCD, but this is a common enough problem.
