GX22GB6400DC Labelled Wrong?

DCat · 18 Nov 2007 at 14:22

I just got an extra 2 sticks of GX22GB6400DC.

One stick is labelled PC2-6400, as I would expect. The other is labelled PC2-3400. But the rest of the labelling on each stick is identical (both say GX22GB6400DC. :confused:

Vista x64 reports 4GB of RAM. Is this just a labelling error ... I don't think PC2-3400 even exists?

Cheers

PC3200 DDR2 definitely exists. I have some. It overclocks nicely though

What about PC3400?

Any ideas on how could I verify whether the RAM stick is actually PC6400?

dcat you can look in cpu-z at it's SPD. And it's probably labeling error.

CPU-Z reports SPD:

Slot #1: PC2-5300 (333 MHz) :eek:

Slot #2: PC2-6400 (400 MHz)
Slot #3: PC2-5300 (333 MHz) :eek:

Slot #4: PC2-6400 (400 MHz)

I bought 2 x 1GB of 6400 initially and then a further 2 x 1GB of the same ... so I guess OC has duped me and I have to send some back? I don't know too much about memory ... is this going to cause me problems if I keep it (looking to overclock my e6600 soon).

Could CPU-Z be wrong?

Has been covered in a few posts on here if you can find them.

Aha, thanks. http://forums.overclockers.co.uk/showthread.php?t=17770397&highlight=geil+5300

I was thinking it was the new stuff which was reporting as 5300 but I'll have to confirm that as it sounds like it must be the other way round.

I have the same mobo as this guy too. Sounds strange to me that I have to do this but I'll have a play in BIOS over the next couple of days.
Thanks for your help.

Even after manually setting the BIOS to the rated speeds and voltage CPU-Z and all other programs that read the SPD chip directly will still show 1 set as 5300. It may be the newer set that is 5300, you don't really know where they came from in the 'pile' of chips that are kept in stock by OCuk or their suppliers.

So should I send it back to OC and request some with reports SPD 6400? In other words, have I got what I paid for or not? Excuse my ignorance.

No. Just configure the rated settings in the BIOS. I own a set that also says 5300 and run perfectly at the rated 6400 speeds. There was a note inside the box to this effect and saying that the memory needed to be configured to run at the rated speeds. I've done that and not had a problem.

Been away for a few days and just had time to do this. I have the DS4 board and did as follows:

- Changed RAM Timings to 4 4 4 12 (from 5 5 5 15 which defaulted in BIOS)

- Changed DDR2 Overvolt to +0.300V

After saving and booting, CPU-Z still reports SPD as 5300 :confused:

EDIT: and I didn't get any note with the RAM
