I honestly think my best strategy is to use the TCCD like it was intended

 

I think that may be a pretty good assessment as well. The Rev1.2 I have; when set to 2.5, 4, 8, 4, will do over 300FSB and you can bet that will pick up the band width. But again yours is not responding anywhere nearly as well as the two sticks I currently have and I am almost of the opinion that if you paid for 2, 2, 2, 5 that you should get it. Problem is you 'can' get it just not with 1T and BIE. Those are two items the 'ramguy' is saying to turn "off" to get the stuff to run the last time I looked at his postings their forum.

 

And then since you major on bandwidth > uh oh you have a rough trip. Not just a case of X jsp user trying to get hearty in a game but a serious affront to one's feelings.

 

You should try what Sharp shows since he does a heck of a lot of digging that I am time-limited against now days. I just happened to run the benches on the 3200XL they sent me and like I said it was 2 sticks against all the problems others have already had just like yourself. Hopefully if you treat them as TCCx stuff that you will get relief.

 

If not I have never forgotten what these 2 users have had to come to the conclusion of when using that brand and for them it was a hard fought lesson of sorts.

Good luck man.

Are you suggesting that if I can't get 2-2-2-5 reliably with BI:On and 1T that my overclocking potential is probably not very good?

 

http://www.dfi-street.com/forum/showpost.p...47&postcount=18 "pgamble's" post about Corsair tolerances.

 

That post really rang true with me. The other about just making sure you got the rated timings right... not as significant. This one is significant because the MB/s throughput is just crap. Sure, maybe people get this expensive working with BI:Off and 2T, and they think, gee I'm getting 2-2-2-5 finally on my $200 memory, so I must be in good shape! But they're wrong, the performance is crap - and yes it is an affront to my feelings. :) More so, I just feel I've been lied to by Corsair.

 

It seems like I have a problem with Corsair, they owe me some new memory. I wouldn't have considered this until I saw that page on their site where you can pick the DFI Ultra-D board, and this exact memory, and it returns a test report indicating everything is fine (except a comment about PCMark's memory test crashing, which they chalk up to a "software problem" whatever the hell THAT means. It's all very dodgy indeed.

 

(Here's that test report page for those interested:

http://memtest.corsairmemory.com/print_rep...-3200XL&id=5030 - they even blame the weather.)

 

What is the model of Corsair RAM you guys would recommend, if I do manage to get an exchange?

BIOS 510-2FIX would be a good BIOS to try.

Also clear the CMOS for 10mins after the BIOS flash.

And do not load any CMOS RELOADED SETTINGS.

hi again minsc. i was at work today and was discussing your problem with a friend who knows quite a bit too. im just wondering, if you ever tried upping your cpus vcore. i know its stupid but maybe the mem controlelr could use some extra juice.

 

Regards, WoL-Shiver

 

p.s. try sharps settings up there, but feed them 2.8 if you can. and add some extra vcore % to your cpu.

Thanks Wol, but I've realized something discussing with RGone - my goal is high memory bandwidth, because that is real. That is the "end", and low timings are just means to that end.

 

I can boot Windows with 1T, 2-2-2-5, and BI:On. It's just highly unstable, but stable enough to run benchmarks. The bandwidth is impressive, but I not extraordinarily so. I think I should use the TCCD as it was intended - overclock the crap out of it - at looser timings, and send my memory bandwidth through the roof.

 

I've started my schooling on overclocking and (possibly tonight) will start experimenting. Wish me luck. If I blow something up, I'll curse Corsair to my deathbed for forcing me into this position. :)

Hey, got about the same set up as you - SLI-DR instead though. Haven't installed the rig yet, I need to make sure that it's possible to use these RAM-modules @ pleasing timings and settings first. So, you've now loosened the timings but you still go 1T BI-On? Keep me updated and I'll post here as soon as I get my rig going (Waiting for a new CPU-cooler).

This is mine that use for winnie , venice and currently the X2.

vdimm will depends on bios version.

misthv I've tried every combo imaginable and just can't get 1T BI:On with my chips. But others have so don't let it discourage you.

Great thread everyone! I also have had trouble with my Corsair memory. After reading through this post and visiting the link in the topic starter by Minsc http://knepfler.com/DFI.htm, my memory issue have gone away. Ran Memtest for hours without a hickup. System no longer mysteriously reboots and games no longer freeze or dump to BSOD.

 

Thanks to every who contributed!
