Upgrading Ram: Need Answers and Advice: 2-2-2-x @2.8V - Page 3

I have been searching for three days now and I still have some unanswered questions, and don't know which ram I need.

I see that most high end PC4000 can run 2-2-2-X timing at high voltages, but my mobo only support a max of 2.8V, so is it possible to under-clock the PC4000 to around 220MHz (DDR440) @2.8v while still running 2-2-2-x timing? If so, Who has done it? Link?

The other end of the table is the PC3500, that can run 2-2-2-x at 2.8v, but I'm afraid it won't be able to run anything higher then that while still keeping timing at 2-2-2-x. Who knows of any PC3500 that are able to run 2-2-2-x @2.8V around 220MHz-230MHz

Lastly, can anyone recommend a ram that meets the following specs:

1GB x2 or 512MB x2
DDR 184pin DIMM
2-2-2-x @ 2.8v
Capable of PC3700 speeds
Cost is not an issue.

I have in one of my systmes OCZ EL DDR PC-3200 Dual Channel Platinum Rev 2
http://www.ocztechnology.com/product...platinum_rev_2
which is running at 215MHz 2-2-2-5.
It's only another 5MHz to 220. If it couldn't do it at 2-2-2-5 I'm sure I would at 2-2-2-6.

Any help?

since my mobo uses NF2 chip they run faster when timing is x-x-x-11

they can run 2-2-2-x until 218Mhz and 2.5-3-3 above that, its good memory but then again that’s what I’m running my Kingston at. The corsair is able to go up to 225 with 2-3-2 which is right on the money.

Asus mobos and corsair RAM is like a match from heaven. That’s why I’m leaning towards it.


I’m getting really frustrated with this memory search isn't there a chip that’s a good medium between high frequency and tight timing.

The board I'm using those OCZ modules in is an Asus A7N8X-E Deluxe.
I haven't actually tried putting the FSB up any higher, but if you like, I can try it for you and report back with the results.

It's a sad, sad day when you are putting more weight on reviews people leave on newegg than what people on a forum such as this say.

And as far as rating RAM to do something... yeah, it does mean something. While not all RAM will do rated timings on all motherboards, that is why there are RAM compatability charts put out by both mobo and RAM manufactures. That is why some RAM runs better on some boards than it does others.
And when manufacturs rate their RAM modules to run specific timings at specific frequencies it is because they were speed binned at that speed. So they were tested and passed testing... so yes it does mean something. That is also why we spend so much more money on specific memory instead of buying value.

that is another noobish statement. what is more important than the manufacture is the specific IC the RAM uses. while in a general sense some motherboards tend to like certain brands better than others the most important thing is what IC's the RAM uses. That is why I said the Corsair RAM you want is extremely overpriced... because it uses the same IC's that the g.skill and OCZ use... so you can complain about OCZ and g.skill all you want and throw your money away... but in the end you will get very similar performance.

On another note... I do have an Asus motherboard and I ran Corsair RAM in it for some time (actually I have some Corsair RAM in it right now!) and my OCZ platinum rev. 2 works much much better than the Corsair. in fact the Corsair has been a horrible match with the board as I have had numerous problems with getting it to run at advertised timings and I had to RMA it 3 times!

Please do not pride this forum as the ultimate knowledge data base, where every member is the ultimate all knowing overclocker, it is a public forum and that’s it. The same people that leave review on newegg or any other site are the same people that post here.
What I look for is patterns and consistency if 3 or more reviews report similar results they can be taken at a greater weight then an anomaly review.

You just rephrased what I said, I can rate one ram on one motherboard and it has nothing to do with it performing the same on a different motherboard.

A noobish statement it may be but no an incorrect one, see what YOU SAID in BOLD

Corsair and Asus have a business partnership, which in terms their memory and mobo work well together that’s all. Yes I’m leaning towards the corsair but haven’t excluded the OCZ or a TCCD based RAM. I’ll do more research call up a few people and manufactures.
