Tracer PC2-8500

[Gautam]

Hmmm, this is my max at 4-4-4. Does it look okay to you guys?

Voltage ? ^^

Insane clocks Gautam, hope mine will get that high, will know when my new m/b arrives.

Those markings are used specifically on the Ballistix-line by Crucial.
In this case -18F means it's memory binned at 1.8ns, or 1.875ns to be precise.
1000 ÷ 1.875 = 533MHz or DDR2-1066 or PC2-8500.

For example, PC2-6400 Ballistix has -25F markings (1000 ÷ 2.5 = 400MHz or DDR2-800).

On mine they printed Ballistix higher so d9gmh can be seen.

Mine is printed over on my tracer but i have -18f and it says D9GMH you can faintly read it behind

Sure that PC8500 = D9GMH on your sticks too ?

[Rubiconx3]

yup i can make out D9GM the H i cant really make out but i assume its there

2.82v (2.775v BIOS set)

[jmax_oc]

Very very good for 2.82V !

[PanteraGSTK]

Just got mine. Will do some testing as soon as I can. Any requests for 650i and 965p chipset testing? Later...

[PanteraGSTK]

Here are my initial results. This is with 1.92v in BIOS using my p5n-e sli. 1m stable.

That's some useful information. So the only difference is the "bin" rating for latency; hence the chips become either an 800 or a 1066, depending how well they turn out after they are manufactured?? Is this right?

[jmax_oc]

After or before but you are right : same chips D9GMH in PC5300/6400/8000/8500 in Ballistix series

[PanteraGSTK]

1m pi stable at 2.013v

I tend to think that they are all the same chip, only the spd is different, the pc rating is only a gimmic. Micron d9gmh all start their life in Singapore, some of them get put in value ram, others go in uber expensive ram with fancy heatspreaders, and others with ott heatspreadrs like ocz and corsair and sell for much much more. At the end of the day they all had a hubble origin.

And yeh some do clock a little higher than others, but that's a luck of the draw, I think, no????

I got this memory on my QuadGT and I can't even hit 600 MHz Highest I've gotten so far is 562.5. Do the sub timings on the QuadGT affect it that much?

I've tried 600MHz at 2.4vdimm with 1.55vmch at 5-6-6-18 and it won't boot

[Rubiconx3]

I can boot 4-4-4-8 600mhz @ 2.4v and run dual 1m pi but thats about it

[Eldonko]

I can boot 4-4-4-8 600mhz @ 2.4v and run dual 1m pi but thats about it

Ditto, but my 8k kit does not scale much at all past 2.45v.

[PanteraGSTK]

Here is 2.178v 1m pi stable. This stuff is awesome.

[PanteraGSTK]

4-4-4-8 doesn't want to work on my 650i board at 600mhz. Kinda frustrating. I can't get past 650mhz for anything. No matter what voltage. I think my S3 will like this memory a lot better, but that is for another day. Voltage doesn't seem to help these dimms at all. Interesting.

could be the board or the memory controller holding you back if that's the case... who knows without testing ram you know can do higher mhz or using a different board

[Rubiconx3]

Im running memtest stable @ 4-4-4-8 1100mhz 2.3v

What are your subtimings?

That's what I was thinking. It will boot at 1300mhz at 2.1v but if I go 1mhz higher I get a memory error beeb. Subtimings may have something to do with. That or unstable vdimm from my motherboard. I wonder if a maximizer is compatible with this board. I'm thinking of getting an I9N, but who knows at this point. I'll see what it can do on my 965 board that is 2.37 vdimm limited. I need eva2000 or somebody else that knows these nvidia boards better than I do.
