max voltage OCZ EL Platinum Revision 2

[overclucker]

whats the max voltage i should be pushing though the OCZ EL Platinum Revision 2? when i get upto 3.0v the computer turns off when getting to the windows loading screen but it passes memtest on 3.0v, but if you try anything higher than 3.0v it will shutdown in 15min or less

heres my RAM

oh yeah and i have a fatilty board

That RAM is based on TCCD or TCC5 chips, so I think 2.9V is max you should go. This samsung chips doesnt like high voltage like Winbond ones do.
And how far did you managed to OC it?

[RedDragonXXX]

TCC5's like higher voltages then your standard TCCD's. I pushed mines all the way up to 3.2V and was running it for some time to stay stable.

However with TCCD's, 3.2V would kill it eventually. 3V is pushing it if you are using TCCD's.

To tell the difference between TCCD and TCC5 look at the label on the ram. If you see a v1.1 in very small print it is TCC5. v1.0 or no v1.x is TCCD. My guess would be you have the TCCD since you are having issues at 3.0v.

yep its tcc5 and i have clocked my fx57 at 3.0 428DDR and 214 core with 2-2-2-5 timings (-;

[overclucker]

do you think its shutting down from under voltage or over voltage? i just got this board so i dont know that much about it.

Just so peple don't always think it's necessarily a rule that TCC5s like voltage, I also have the 2x512mb OCZ Plat R2s with the little v1.1 in the corner. I'm currently running mine at 285mhz, 2.5-3-3-8 at 2.6v (MBM5 shows 2.61v). These are memtest and prime stable at these settings. I've tried 2.7, 2.8, 2.9 and 3.0v and 3.1v with this set and each setting has gotten me progressively more memtest errors. So 2.6v seems to be the sweet spot for me...

[overclucker]

hmm guess your setup drowns it in voltage, mine wont even boot at 2.60v

[Gorki]

tyson-chris that is VERRy good oc with TCC5 chips...Mine also detects 2.6v by bios default insted 2.7 as for TCCD ones... Have you tried push it more (FSB mhz)? Neverles it's nice to have 285 fsb at 2.6v lol! :-)

[tyson-chris]

Yah, I'm definitely pleased with it. I've tried bumping up the fsb and I get errors fairly quickly. My cpu is also a dog, it won't do 260x10 stable, even up to 1.6v. So I leave it at 285x9, at 1.45v on the cpu. I've even tried super loosening the mem timings to 2.5-4-4, and I don't get higher than 285. I actually think it might be the board that can't do the higher HTT, because I've tried higher HTT with a mem divider, and it's still not stable.

But yah, I'm not complaining, I don't really need the incremental speed.

I kept having problems with system stablity issues and Memtest errors with my 3200 EL Platinum Rev2's @ DDR444, 2-2-2-5 T1 (222Mhz FSB - 1:1). I noticed I got less and less errors I as I increased their voltage. They seem to be very stable at the those settings [knocks on wood] given 3.0 volts. I'm running them on a Asus A8N-SLI Premium.

A minor point. If you are running >2.8V, do you have active cooling i.e atleast 2 x 80mm fans blowing over the RAM? That is very important and necessary.

This is good advice but I wouldn't say it's always absolutely necessary. I don't have any fans directly on the modules but I do have a good air flow in my case. The memory is rated up to 2.9v. I'm only running them 1/10 of a volt higher. If I were going above that I would probably then up the cooling system a bit. Since over-heating usualy causes errors I would most likely know if it became a problem. Right now I get no errors in 2 passes in Memtest and the system is running smoothly.

[Super Nade]

Sorry to say, but 2 passes of test #5 means nothing. In my experience, a reasonable wall time would be 4 hours. I said 2.8V because I'm referring to TCCD in addition to TCC5. If it is warm to the touch during a memtest run, you are asking for trouble. Since warm is a relative term, I'd say >6C above ambient is not good. Plus, it doesn't hurt to slap in a few extra fans. :D

1/10th of a Volt doesn't mean the rise in temprature would be proportionate. The scaling beyond a certain point is not linear. I have found that this point is 2.85-2.9V for TCCD.

Just a heads up on the issues I have had to face due to insufficient Memory cooling. :)

Edit*
I forgot to add, that I had owned these very same modules and they do get very warm at 3.0V.

OK, understandable - but let me put it this way. XP used to crash/freeze a lot randomly. I ran some Memtests (min. 2 passes ~30min) and got lots of errors. Everytime I upped the memory voltage (the only changes I made at all) I would get less and less errors in Memtest. I finally got it to no errors in two passes when I changed to 3 volts. I also noticed Windows or games didn't act up like they used to.

So taking your advice I decided to run Memtest longer than my usual 2-3 passes. I started it last evening a little after 3 PM and came back to check on it at 8 PM. No errors :). I would also like to add that I can't remember the last time XP or any apps have crashed/froze since I put the vdimm @ 3v. I suppose my situation could be the exception but it doesn't really matter, I'm pleased with the results.

All that said I'll be picking up a few 80mm fans :p Have any suggestions on the most quiet models?
