Ram SPD questions

[Spike]

Last night I installed my new OCZ Plat 2 x 1gb 2-3-2-5 in my Abit NF7-S v2 mobo with a AXP 2500+ @ 3200+. The auto-detect in the BIOS set the ram at a CL of 2.5 instead of 2. I manually corrected this and played about an hour of AOE 3 before it crashed. I have not had the game crash before so I am a little concerned which brings me to my actual questions.

What is the 2-3-2-5 actually referring to? I know that the first 2 is CL but what is the abbreviation for the last three? I want to make sure I have the correct value for the correct variables in the BIOS. Also, is there any reason why this ram would have issues running at these timings in a Socket A setup? All the info I have read is relating to a A64 setup...

Before someone mentions it, I do plan on running memtest tonight as I did not have enough time last night. I just want to make sure all my spd settings are correct before I do the tests. thanks!

How much vdimm are you using? Try using at least 2.7vdimm.

You should ask this in the OCZ support thread under CPUs/Overclocking forums for more detailed response.

Hmm, I did not know that thread existed, I will check it out.

I have no idea what the voltage is, I left everything stock except for changing the CL from 2.5 to 2.

search your bios some more for the vdimm.

pehaps you set the tRCD and tRP mixed up, ie your trying to run 2-2-3-5. Try loosening the timings to 2-3-3-6.

Do you have a link to your ram?
And are you saying that it was advertised as cas 2 but the spd said 2.5? Bumping up the voltage might help but its overclocking if the ram wasn't meant to be cas in the first place.

This is my ram, I know it is 2-3-2-5 as thats what newegg and OCZ tell me. I am going to play a little bit more tonight and see whats going on

What spd setting does the cpuz utiliy tell? The abbreviations will be given in cpuz.
And if its not stable at 2.6v, I wouldn't recommend bumping up the voltage since its failing at stock. Just rma if it doesn't work.

I am actually running memtest on it right now at 2.8v. As OCZ garuntees it up to 2.8 I figure it's ok. If it continues to fail (It had errors at 2.7v) I will RMA for another pair from newegg.

I did finally figure out the latency numbers and after changing the 2.5 to 2 it is where it's supposed to be. I just hope it passes at 2.8, I hate the hassel of RMA's.

EDIT I just noticed the stock voltage is 2.6v. After I finish memtest at 2.8 I am going to run it at 2.6 as I have not done that yet.

Why so eager to bump voltage? Should people bump up the voltages on an AMD cpu as well if it isn't working at stock?
Isn't the fact that the SPD is giving a CAS of 2.5 instead of 2 seem odd?
Running modules above 2.6v is shortening its lifespan imo which isn't exactly what you paid for.

In this case bumping the voltage means nothing to the rams life as if it EVER fails at 2.8 I can RMA it to OCZ for a replacement as it is covered in there lifetime warranty.

This particular board I have has never detected the ram I have had at the supposed stock timings so I am not real concerned that it did it again this time. And I did bump the voltage to my AMD cpu but thats because I overclocked it 😉

I did post this in the official ocz thread so I will probably stop updating this one but as of right now the ram is failing memtest at every voltage so I need to find out if the ram is bad or if something else does not like it in my system. thanks for the replies!
