they do 600mhz 5-4-4-12 at 2.575vQuote:

I have a Corsair Dominator PC2-6400 2GB ram and I am using it with Striker Extreme Mobo, E6600, 8800gtx.
I have specified the timings on the mobo to work at 4-4-4-12 (2T) timings and frequency to 800mhz. But when i run CPU-Z in windows it shows me frequency of 400.9 mhz only with fsb:dram 2:3. Could you tell me why does it not show me 800mhz...?
It is running at 800mhz......
its called DOUBLE data rate.
u gotta x2 it from the CPU-Z number.
thats great, thanks
Hmm I've been noticing a bit of a problem with my OC and was wondering if any1 of u guys had any insight on the situation.
I've used orthos Small FFT to test my CPU and it can go 18+ hours with no problem.
The problem is when I run Large or Blend FFT. It will only run about 30min to 1 hour before stopping. But when i go use Memtest it passes without a hitch for 10+ hours.
Well originally I figure its probably the ram but i tried various speeds, timings and voltages and no matter what large FFT's fail in about the same time.
I even set the ram back to stock speeds 800mhz 2t with everything at auto.
I'm a bit stumped so if anyone can shed some light on the situation that would b awsome.
The settings are in my sig.
Memtest is not strenuous enough to truly determine stability.
Orthos is indicating that there is an issue with the RAM stability, or perhaps too high of a FSB and you are running into chipset stability. Also, the large FFT and Blend test tend to toast the CPU a lot more than small FFTs, so perhaps we are running into a heat issue... hard to tell unless we have some more specifics about your rig.
For more accurate results out of memtest86+, run test 5 on constant loop... thats more accurate IMO than running the entire suite.
I don't think its a heat issue cuz I've tried lowering the CPU to 3.4ghz and i still get this issue but if that's the case I'm still waiting for these new thermalright coolers 2 come out. I'm also considering swapping out the huge array of heat pipes with thermalright coolers.
I did however manage 2 run my ram much longer on orthos when i put less than 2.0v in it.
BTW the ram just goes to hell whenever I put anything over 2.3v to it.
It seems really odd if my ram cannot even take over 2.0v.
I've also noticed that on Large FFT my Ram meter shows its only using about 30% of the ram whereas blend uses about 82%. Is it supposed to do that?
I'm just thinking maybe I just have some REALLY :banana::banana::banana::banana:ty sticks of ram. I see eva getting such nice results with the same sticks but mine won't break 1130 on 2t not to mention i'm getting these errors at 800mhz 2t....
It just really pisses me off that there are errors at reference speeds.
Another funny thing about the ram is that orthos takes the same amount of time to fail at 800mhz and 900mhz 1t or 2t which makes no sense to me
Hi , does the striker automatically see 4 gig of ram or do you need to enable something? thats 4 x 1 gig sticks , I will be trying it with vista 32bit , anyone already using that with 4 x 1 gig sticks
no probs with 4x1GB Gskill 6400PHU2 HZ D9GMH 629 batch @500mhz 4-4-4-12 at 2.25v vdimm http://i4memory.com/showthread.php?t=3744
automatically sees 4GB IIRC

Also, is that the lowest timings you found stable for 500mhz at 2.25v?
2T.. didn't test higher than 500mhz to be honest since i've sold 2 sets of the 6400 HZ only have 1 set left so no 4GB config for the moment
Thanks for that Eva , i have another question about E6750 cpu's and that is is it supported with current bios release for the striker
Eva, is it true that a BIOS can affect the memory command rate? I heard that some people using BIOS 1004 can run at 1T but when they tried the new BIOS 1102 they cannot run 1T anymore, only 2T.Quote:

As to E6750 no idea.. maybe 1102 beta updates the cpu codes for it ???
I run 1T and 2T the same on both 1004 and 1102.
BTW i figured out my instability issues, it wasn't the ram.
I knew different BIOs could change your OC results but I didnt know also affect the RAM. Thanks for the tip eva ;)
Hmmm, I cannot run 1T for some reason, it will give me error on 1102 but didnt give it enough testing on 1004.
Right now im running 1000mhz 4-4-4-10 at 2.250v which I think is pretty good ;) havent test it any further, I heard people running the same configuration but at 2.200v and others running 1000mhz with 4-3-3-6 at 2.35v. I will have to find out
Is it really hard to run 1T at 1000mhz? do I need a voltage pump to run 1T?
You have a nice E6600 in there ineedaname. Im about to get another CPU but still dont know if I should go for a E6600 or E6420...
all my high end micron d9xxx ram hit a ceiling at 440-450mhz 1T and need around 2.3-2.4+ vdimm which is normal for 680i chipset and 1T
Ill try 1000mhz 4-4-4-10 at 2.3v and see if that works with 1T, but I saw your results and 1T had really close results compared to 2T so if I cant run 1T Ill be happy with 2T since there is not that much difference on many tests.
I heard micron chips shouldnt get more than 2.3v or they will start to get damage, is this true? as far as I know 2.4 is the highest and safest voltage for the RAM.
It's been said micron d9 starts to get dangerous at 2.4v and above so keeping under 2.3v would for 24/7 would be better but i've only benched at 2.4-2.6v with no problems ... every day i'm happy with 500-533mhz 4-4-4-5 tight sub timings at 2.25v vdimm on 965/975 or 500-533mhz 4-3-3-4 2T with tight sub timings at 2.25v
Hey eva i was just wondering. What's the difference on your board between ur vmem and vcore using actual measure point compared to probe.
BTW Bios 1102 is official now http://support.asus.com/download/dow...%20Extreme
Yeah but is not what everybody was waiting for... looking for the next BIOS anciously
I really want to achieve something like 4-3-4-5 2T at 2.3v max, that would be pretty nice.
So far I love my G.Skill memory, dont know what IC I have but I know is some good micron.
My last corsair pair could only do 4-4-4-12 at 900mhz and needed 2.2v to work, from 900mhz and up it needed the latency to be increased to 5. A nightmare.
yea i heard that 1104 beta is in the works so hopefully that'll b out soon.
At least we know they didn't stop revising the bios yet.
That would piss me off so much.
what can we expect from 1104? better memory compatibility, better hard drive compatibility, more microcodes?? I dont want that! I want something like OC improvements or Quad-Core OC Improvement or Core 2 OC Improvements.
Never saw that in ASUS history.
well the earlier 0503 bios was utter crap so there was quite an improvement. So they do have some improvements for ocing.
But then again if they didn't make it so badly to begin with then...
Hi , just fitted a Q6600 in place of my old E6700 and all seems fine apart from temps are really low showing 18 degrees in bios and same using asus probe , cpu is at stock until i can trust the temps , any ideas , i am on 1102 bios
