O/Cing Corsair PC2 8500 on a P5N32-E Sli Mobo - Help

[dipankarmohanty]

First,

 

I'm running these sticks at 5-4-4-12 at 2.125 stable at 1120 Mhz. Is it possible to get more out of these sticks?

 

I've tried increasing the voltages to 2.4 and loosening the timings and try to reach 1200 MHz but still it doesn't work

 

So my question was, is it worthwhile to increase its speed. I mean performance wise would it make a difference?

 

Any suggestions?

 

And Yes, I'm running a core 2 duo E6750 2.66 ghz at 3.2Ghz.

 

In this config all games are running smooth except crysis of course!!

Interesting Timmings.

I have 4 GIG of the Dominator PC2 8500 and at 5,5,5,15 I'm at 1066.

I've wondered how to get it running faster because it just seems to be lazy.

I've heard that if I lose 2 GIG the RAM will run faster but I paid all that money to have the headroom, now I'm being told it was a waste...

I'll have to try 5,4,4,12 and see what it does.

Sorry I can't help with your question.

 

I play allot and I really was looking forward to Crysis but hearing all the bad news I guess I'll save my money untill a patch comes out, LOL!

I think the Asus p5n32 board has allowed me the timings of 5-4-4-12 but I get the feeling that this is not stable at times. Crysis keeps crashing, but the other games have no problems. So now I've set them to 5-5-5-15 @1120. So lets see what happens. I'm not a guru in overclocking but the RAM is not that overclockable from what I've heard. Looks like I've wasted $50 dollars. Ah well

 

By the way, you've got a bad mother of a system. Did you sell an organ for it or what? With the kind of system you have Crysis, should be comfortable to play at decent framerates.

Do they really claim the ram itself oclocks anywhere? If so Id like to read it...(serious not being sarcastic just to be clear).

 

The way I understand it is, its Oclocker's ram. The diff being, its ram for oclockers NOT ram to be oclocked to x mhz.

 

WTH does that mean?

 

Simple, you have 800mhz jdec ram spec. You have a cpu and setup to run at 800mhz ram. You pop in this ram and NOW you can raise the cpu fsb up towards the 1066mhz ram mhz without bumping the divisor down.

 

 

Thats how I understood it anyways. WEll that and, they wont void warrenty for messing with timings/mhz aslong as you dont overvolt. Keep in mind this is alot more then other brands offer. Buffffalo ram for instance told me ANY setting in bios on cpu OR ram that is not auto will void warrenty. If ram doesnt work auto were sorry but its not defective persay however your stuck with it. Roseeeeeewill ram did the samething to us (system builder). Corsair has better warrenty and KNOWS their ram, the other guys couldnt even tell me timings other then set to auto or void warrenty.

LOL! Naaa, I didn't sell a Kidney, just 2 Kids and a Dog to the University of Kentucky Reaserch center... :O)

It's a long story but let's just say I was able for once in my Life to go all out and build a Rig with no restrictions. I did get a score of 15,888 on 3D Mark6 but I refuse to pay the $20 to make it official, LOL!

 

If you're running all kinds of other programs and everything is stable then I don't think your Timing is the issue. I've read that Crysis is a little quirky with Direct X10.

 

I started another post about overclocking and I think it's just the nature of the beast when it comes to competition between manufacturers.

Yes, you can O/C this RAM without worry of voiding the warranty if you don't over volt but the true meaning of O/C when it comes to Dominator RAM is its ability to match the CPU in performance to ballance everything out. That way you can keep it as close to 1:1 as possible, making data flow smothly with less chance of Bottlenecking. I/m no O/C expert but that's what I get out of everything I've read and my personal experience.

I guess what everyone is assuming is the fact that Dominator RAM is set up for SLI M/Boards, especially nVidia.

With the RAM matched to these M/Boards the SLI O/C option is oppened up but it's not really overclocking but just nVidia's way of getting the RAM and CPU in tune with each other so you can max out the specs of both with the smallest divisor. I just wish nVidia wouldn't call it O/C because it's not and yes, it states in the BIOS O/C enabled. You have the option of 0-5% O/C or Max O/C and expert O/C modes within the BIOS.

 

Even with that being said mine runs at 2:1 why? because the RAM is dual Chanel running at 533MHz and the CPU is running at 1066MHz 266.5MHz X4 so therefore you get 2:1...

It would be the same with the DDR3 at 1333MHz. You're actualy running at 666.5, ewww, I never ran the numbers but that's just not right, LOL! It's the Devils FSB...;O)

Anyway, with the new QX6850 running at 1333MHz 333.25MHz X4 you'll still get the 2:1 divisor.

Some People claim to get higher performance out of their systems by slowing the FSB of the RAM down to match the CPU's but I just don't know, my Rig seems to be running OK where it's at.

All I know is that I'm not going to over Volt my $500.00 Ram or my $1300.00 CPU for spits and giggles...

O.K. thanks for explaining. I can see where the confusion is from then. Not really wrong but ya misleading. Just like nvidia's "way its ment to be played" some actually think to see the game as the designer intended you MUST have a nvidia. It works- sound dumb I know but it does I have seen it in action! This coming from a long time nvidia owner (since geforce3 I payed $400 for). Bottom line, never trust marketing its the golden rule for any shopper.

 

Myself, I never bought into auto oclocking applications even at the bios level....My old asus had AI for auto clocking, this one has clocking engine v6 v8 and v10 modes. Never used them as they get gready with voltage and give little boost really for the heat it makes. Im old school-set it-know it-Clock it. I got 20% oclock on my cpu with stock vcore for example to get that auto Id need v-10 settings with a nice raise in vcore (1.20v to 1.35 I think) So with this ram, Im gonna guess (since I dont have any of it) that clocking manually goes much further then auto mode.
