Ballistix PC8500

[Zolly]

On my Crucial Ballistix pc6400 is "0728-25F" writen, any idea what it means?

don't worry, those are D9GHM's

Why so many crucial ballistix pc 6400 not stable 4-4-4-12, 1000mhz at 2.2 v ?

Mine too.

[BeardyMan]

because they only shine with cas 5 at high speeds. give them 2.45V or 2.5V and you will see what i mean

Wow, I know I ask hard questions but when you drop $150+ on RAM I would assume some people would know these numbers...

Well, I found the timings....Many of you guys don't realize your motherboards are OCing your RAM at default settings

You could probably get higher bandwidth if you knew what the values are suppose to be set at...

If I give 2.4 or more voltage the rams are damaged

not really, if we are talking about 24/7 use, chances ar high yes, but for benching purpose a good old 120mm fan wil do

sometimes you gotta dare to take risks

[vera]

Yes, I want to use 24/7

[BeardyMan]

Yes, I want to use 24/7

then you should be able to pump 2.3,2/35V trough them with active cooling

[LyP0]

I wouldent reccomend that, i had a set of gskill pc8500 2gbhk. Those where killed in like to weeks with a voltage of only 2.3v and cooled by ocz xtc memory cooler ( 2 fan's ). i'd stay on 2.25v to be sure cause some boards overvolt a little.

woah crazy mem clocks there 724mhz 6-5-5-15 at 2.7v

I was thinking of upgrading my memory to pc8500 from pc6400. These ram are the talk of the town. I was thinking; is there really a performance boost by going from pc6400 to pc8500? My pc6400 run 4-4-4-12 at stock and I have run them as high as 1077Mhz at 5-5-5-15, which is the 'stock' timings for this pc8500 ram running at 1066Mhz. So, it appears to me these are repackaged pc6400 with relaxed timings (5-5-5-15). Is this just a marketing ploy?

Don't bother, the performance benefit of increasing your RAM speed will be negligible (AT BEST).

And yes, these Ballistix are just repackaged PC2-6400 chips. But they've been tested to run at PC2-8500 speeds.

You see many show SuperPI benchmarks because that's the only program that shows a measurable difference in performance. So if you wanted maybe 2% gain at calculating pi to 1 million digits then go for it.

Otherwise, put that money into something more worthwhile like a graphics card/hard drive/CPU.

[Saturas]

As CoW]8(0) already said.

If you use them only at standard speeds you won't see or feel any difference,
only in Benchmarks like SuperPi oder Aquamark3 Memoryperformance makes a quite big diffrence.

The BallistiX 8500 seem to have the best selected Micron Chips,
cause they often are highly overclockable and reach better clocks and timings than any other DIMMs.

Upgrading from 6400 to 8500 is only useful for benching.

Real Voltage DMM 2.63~2.64V

[Kain665]

4v or 2.64v?

[h3x0r_1984]

These are my results with 6400 Ballistix:
Except the 1280Mhz 1M run(2.3V),all the rest were done at 2.2V DMM.I didn't know how to adjust the performance level when i was clocking with 4 4 4 4,so i got only 960 (4 4 4 4 ,2,25V).I'll try again,but the best deal for me is the 1066,cause i can keep my E4300@3200mhz.Look at he performance level at 1280,wich is lower than the cas,so i think there's more to be juiced out of them yet.

I found a really good deal on the Crucial Ballistix PC2-8500 DDR2 2GB 2X1GB DDR2-1066 CL5-5-5-15 240PIN DIMM Dual Channel Memory Kit in Canada and ordered a set. They were only $84.99 Canadian after mail in rebate. Is it all right to post a link to the sight? First post here and don't want to make it my last!!!

[Monstru]

Ok, so here are my sweet Crucial Ballistix 8500 tested on Dfi Infinity P965-S with an E6600 CPU, goal - Spi 1M stable

2.10v

3-3-3-9 ..................................... 407Mhz - DDR2 814
4-4-4-12 ................................... 541Mhz - DDR2 1082
5-5-5-12 ................................... 604Mhz - DDR2 1208


2.30v

3-3-3-9 ..................................... 435Mhz - DDR2 870
4-4-4-12 ................................... 566Mhz - DDR2 1132
5-5-5-12 ................................... 607Mhz - DDR2 1214


2.40v

3-3-3-3 ................................... 458 Mhz - DDR2 916
4-4-3-4 ................................... 500 Mhz - DDR2 1000
4-4-4-4 ................................... 600 Mhz - DDR2 1200

While it is obvious that I am limited at around 1200 due to the motherboard, good latencies at low volts are my favourite on this board, and this kit seems to be very happy with that

Hope that is ok with the pictures stored elsewhere, I have too many of them.

Hi everybody.
I am new here and a rookie so sorry for my bad english.
I have a same kit and they can do 1300ddr2 dc with 2.55 vdimm 1m pi stable.One of them can reach 1400mhz with 2.55 cas 5-6-6-18.

[kingfearon]

I got PC2 8500 on ip35E and E6750

I dont want to OC the CPU just mem looking to get, so should i lower the CPU multi then raise Bus Speed ?

Or in order to get a 1:1 ratio, do i have to set the bios mem ratio below 1:1, lower the CPU multi then raise the FSB ?

Or in this case a 1:1 ratio doesnt matter.

I am a noob.

[swiftex]

p/u 4 sticks of the PC2-8500 (sans bling), so easy to work with

[CERO]

I got a pretty new Batch it does 1167mhz 5-5-4-9, @ 2.05v memtest/prime stable 13h / 19 h respectively. these ram are top notch
