Guide to RAM - Page 2

Well, my old Elixir stuff overclocked 20MHz, or 40MHz DDR, and that was pretty decent (for generic RAM anyway.) You'll just have to see how well yours will do, and if you hit a wall, give it more voltage or relax the timings.... or both

. I wouldn't expect anything amazing, but I think you know not to expect that kind of outcome already... Also remember your board has no PCI lock, but you knew that too.

Isn't the read and write speed of ddr400 ram at least 3gbps?
I mean is speeding up the latency at all noticeable... given that read time from a hard disk is 70mbps max and probably more likely 40-50mbps

Wildstyle... dumb question, in 2 2 2 6 T1, what does the T1
stand for and why is it so much faster than T2 ?
Thanks

It can't be a dumb question... I don't know the answer, LoL!

Yeah.. uhm I've never had to deal with those 1T, 2T things, though I know what you mean.. I just don't know exactly what they are and what they mean/do.

(That was hard for me to admit.

)

Thank you!

Well I know it's the Command Rate.... but what does it mean?

WildStyle · 08-05-2004, 00:32 | posts: 15,236 | Location: UK

Still nobody knows? I go away for 2 weeks... come back.. and the question still remains!? Hehe.

I've seen it a eveywhere, but never with some sort of explanation attached. Still waiting to know...

Google to the rescue:

A bit dated as far as the chipsets they're talking about, but I'm sure the principle remains the same.

Here's some newer info I found:

today i bought a set 2x512mb KHX3200ULK2
timing should be 2,2,2,5,1(http://www.valueram.com/datasheets/khx3200ul_512.pdf)
but it cannot even run stable at 2,5 3 3 6
i tried everything, to run at 166mhz, to give 2.8v
somehow the best settings are 2 4 4 8
can somebody help me or i have to write to kingstone

thx

I'd just RMA it because you seem to have tried everything I'd have suggested and it's still not working right...
Could also be an incompatibility with your board, perhaps.

I have bought the memory right ------> but it does not work at 200mhz speed because of incompatabilitys with nforce 2! DOHH!

Overclockers wont have it back as they say its "not faulty". Is there ANY way i can get this memory to run at 200mhz. I have tried changing from 7,3,3,2.5 to 8,3,3,2.5 and 8,4,4,3.0 and nothing.

I have options for aggressive, turbo and can change to 133,166,200 for mem speed.

Also i heard that 11 RAS is good for nforce2. Why?

I also have a stick of 133 ram (my current ram is going at 166)
I was wondering if i dont get to 200mhz could i pop that 133 stick in and work ok? Its not much of a difference is it? mmm.....

Thanks all!

Try increasing the vdimm.... upwards of 2.9v should be plenty safe. That's actually pretty popular RAM, I doubt there is a strict incompatability.

08-29-2004, 19:38 | posts: n/a

vdimm?

My motherboard manual says that i dont have to change any (read cant) voltages in anyway shape or form. Its says i dont have to, its automatic for everything!

Any suggestions? I can change everything else though i guess...

G L · 08-29-2004, 19:50 | posts: 10,261 | Location: San Ramon, California

In that case I don't see what you could do... I guess you could try switching the order of the two dimms, but that's not too likely to help of course... Dual-channel does virtually nothing for the XP, by the way, not worth losing sleep over.

And Ultra memory, which I have.

Hadn't heard of them at the time of writing.

just giving an update

G L · 09-27-2004, 02:35 | posts: 10,261 | Location: San Ramon, California

Ultra used to be a tigerdirect only brand, I believe... though whether they are owned by tigerdirect or just used to be an exclusive supplier I'm not sure.

Whether it is or not, I guess it doesn't really matter. I haven't had a single problem with it and it overclocks nicely, with good performance. Prime95 ran for several hours detected no errors.
