Are these OCZ platinum good?

I bought a P5B because my ds3 would overclock my dual great and not my quad(was limited to stock).

The RAM I own now is a 4-4-4-12 ddr1000 g.skill set rated 2.2-2.3v. This board only seems to have auto, 1.8, 1.9, 2.0, and 2.1 for vdimm in the BIOS, rendering my current memory useless.

I was going to keep the memory I had now in the quad core and buy some cheap 1 gig set for my dual core. Instead, I want to put the 2.3v memory in the dual core with the ds3 and buy memory that will do at least ddr1000 at 2.1v so I can run it in the main board.

I am kind of skeptical since it works at 2.1v, but OCZ's reputation precedes them, so I want to buy. I was hoping for any opinions before I pull the trigger.

Thanks in advance. :)

They're using D9GMH ICs probably ( send a pm to RyderOCZ or AndyOCZ for confirmation ), so 2.1V DDR2-1000 5-5-5-x should be a "easy target".

[Thasp]

Ah, thanks. I will order a pair now. Although the urge to voltmod the P5B until these arrive before the g.skill gets put in the dual core ram-less system is quite strong. :D

Friend have one stick of 800mhz platinum, is Elpida (or PSC) and don't wanna do more than 960mhz 5-5-5 2.1V. More voltage or relaxed timings dont help.

You're probably talking about the PC2-6400 Platinum Edition, which use ProMOS chips or Elpida, that's why you're limited there.

Yes, elpida is trash - but by nature of these being rated to pc8500, I doubt they are elpida.

I've always read D9 as being 2.2v minimum for good overclocking results memory, I never knew there were different chips that'd go this high at 2.1. Thanks! :)

I heard somewhere that OCZ pc2 7200 and above have D9's of some sort.

I have 2x512 Platinum XTC DDR2 800 pc2 6400 bought last Feb that together can do 1100mhz and orthos stable 1080mhz. Now, recently I got another set of the same 2x512 and one of them can't do 32m Spi at 880mhz. That's 200mhz difference. I think the newer ones have different chips that, as you say, are 'trash'.:yepp:

thats weird cuz rev1 sticks were Elpida and the newer rev2 is ProMOS.
i would expect ProMOS to clock better than Elpida

The newer set I got are also rev.1, I think the newer batches of rev.1 have inferior chips, and does not OC as well as the older batch. That's from my own experience, good thing Ballistix have gone down in price, cuz the OCZ's are no good to me now.:shakes:

[Thasp]

I just bought them since I failed miserably soldering a vdimm mod onto this asus. I consider it an accomplishment I was able to get it back to the way it was before my resin spooge job on the board.

I will do extensive testing once I get them. :)

This info is correct. You have purchased Micron D9 based memory. You should do fine with it. Use the latest BIOS.

[Donkers]

andyOCZ why such a big performance gap from my older xtc's to the newer ones of same version? Were the older ones Elpida as zert mentioned, and newer ones some sort of value rams?:)

The 512mb PC2-6400 Modules have always been PSC (Powerchip) chips. According to my latest info they still are.

Understand that different batches of the same chips can be capable of faster speeds. Then you must consider that if one IC on a module is not as fast as the rest, you might get only 880mhz out of that module. These kits are tested at 800mhz plus some headroom to be sure they will run reliably. We would never test 800mhz ram at 1000mhz or higher; if we did we would sell it as PC2-8000 or PC2-8500.

The rules of overclocking have not changed; if you buy 800mhz RAM and it runs 1080mhz you are very lucky. If it runs 880mhz you still exceeded specs.

I'm sorry one of your sticks does 880mhz.

[Thasp]

I am still surprised at th idea of any D9 based chip doing a thing at 2.1v. I can't run two sticks at the same time at 2.1v and get anything done with the set I have now, 5-6-6-16 and the loosest of the rest timings is what I am using just so it'll work in the ddr900s-1000 range, since it's ddr1000 2.2-2.3v rated memory.

I should have these sticks tomorrow. I'll post back how great they are(if so, I'm expecting it with the specs and OCZ"s reputation :)) once I mess with them. :)

You should be greatfull for what you got the first time and dont think you got ripped off cos the 2nd set didnt overclock as high..... are you sure you tested them the same?.....:stick: it could be just user error cos my experience with OCZ has always been good and their rams has been very consistent

You've got to be kidding Luihed. :slapass:
My apologies to OP :off:

[BenchZowner]

Chill out.

[Thasp]

I enjoy the back and forth, it gives me an insight into what other people think from those with different/more experience. :)

If it's PSC or elpida, there's no way around it.. it's not going to overclock that great. It's not the manufacturer's fault that their memory performs at spec. I can't turn :banana::banana::banana::banana: into gold, and OCZ(or anyone else for that matter) can't turn elpida(or other lesser performing ICs) into D9, and that's fine because the memory isn't advertized as being DDR900, or an overclocker's dream.

Sorry about the noise, I was just having fun with an old friend, and I just can't resist trying out those new funny icons, especially this-> :slapass:

Anyway, I know that even D9GMH's don't all clock the same. I was just curious...as they say, knowledge is power. And from the answer I got above, we now know that there could be as much as 300mhz difference on a particular chip. I don't feel ripped off, I'm a good sport, just sold the duds, :) and keeping the monsters, playing with Ballistix, life goes on... :up:

[Thasp]

I bought the SLI ones by mistake, but they have the same bandwidth, voltage, timing spec, and price as the platinums. They do indeed kick ass. :)

[newls1]

The Crucial Ballistix PC8500 Ram can run @ 2.1v no problem. Im currently operating mine @ DDR1013 4/4/4/10/4/35/10/10/10/10 @ 2.1v (P5B-DLX) Really excellent RAM.

[Donkers]

Thasp, any numbers we can look at?

[Hutch]

Thasp upgrade your bios to the latest F11B. In the newer bios you can select up to 2.5V for the vdimm.

[lawrywild]

AndyOCZ, have the PC-7200 SLI 4-4-3-15 still got D9GKX?

[RyderOCZ]

Their may have been some sets that went out the door as GKX, but in general they have been GMH.
