G.Skill F2-6400CL5D-4GBPQ does indeed use Powerchips...

I'm no guru, but there are some things i do know.

One of them is that Micron [rev. E] D9HNL doesn't clock worth crap; never has, never will. Usually you're lucky to get DDR2-900 5-5-5 with it, if that even.

It's nowhere remotely close to as good for OCing as the infamous Micron [rev. D] D9GMH or D9GKX.

Now everyone who has been getting the well regarded G.Skill F2-6400CL5D-4GBPQ has been getting good results, far better than you can achieve with D9HNL.

So i naturally assumed it was using the same Powerchips ICs (possibly just lower binned) as the DDR2-1000 kit G.Skill puts out, but apparently some don't, as witnessed by r00n's DDR2 RAM List: http://ramlist.ath.cx/ddr2/

I wouldn't normally care, but since we have Cheex posting in every RAM thread about how awesome this particular kit is because it uses [what's actually very average] D9HNL, i had to get to the bottom of this ;)

So i did: http://www.xtremesystems.org/f...howthread.php?t=173729

Obviously, some of the original kits did have Micron.
But as anyone who OCs would know, those kits won't get very far.
As the pics in that thread indicate, the newer better clocking kits are using Powerchips, just like their DDR2-1000 brother is.

Now Cheex, go check the DDR2 list & see what it lists under your kit for ICs ;)

Well first of all...
r00n's RAM List apparently has just been updated to show this information (Powerchip).

I will concede, and stand corrected, that that information is indeed correct.

I have never pulled off my heatspreaders to check the actual ICs.
However, that being the case, are you saying that the Powerchip ICs in this kit are better for overclocking than the Microns?

Hard to believe but I guess it is true.

I have run my kit @ 1000 @ 2.0V - some minor instabilities popped up after a while so I'm guessing 2.1V would fix that.

Same for 860 @ 1.8V - I bumped that up to 1.9V to fix that.

I will then also agree with Cordovader from XtremeSystems that I'm happy that these clock so well and are not Microns...:p

Its all good.
At least, nobody that I've recommended this memory to, will be disappointed...:thumbsup:

Thank you n7 for your constructive criticism...:beer:

Yes, you have been recommending great memory; so have I (it's a fantastic value).

I just hate when info gets mixed up, & even though i couldn't prove it till now, i knew there was no way the current kits were using D9HNL, since it doesn't OC well at all.

That's why i made the post there, since i know r00n hangs out there, & i knew all i needed was to find someone willing to pop off their heatspreaders to prove my theory.


If you followed the RAM IC scene a bit more closely, you'd have known that it couldn't be D9HNL, like i'd tried to tell you all along.
And you'd also know that the best clocking 2x2 GB stuff is Powerchips, aside from the older D9GSV, which Mushkin used in their older 2x2 GB kits.
Technically, if you can actually find a D9GSV kit in stock for a decent price somewhere, it'd likely clock better than the Powerchips do, but Mushkin has discontinued all those kits that used that IC, & it needed heavy vdimm to achieve really good results, which we all know isn't good for Micron (since it likes dying too fast then).

Right now, Powerchips actually do seem to be the best bang for the buck option right now, as they clock well, are cheap, & don't need much vdimm.

Perfect for those excellent G.Skill 2x2 GB kits :)

/let's just hope G.Skill doesn't switch back to using Micron though, or people won't be getting nearly the same success with OCing...

That's true. In fact, it might serve me well to get my other 4GB as soon as is possible for me...:p

He pointed me to this thread.

The point is, the information is still pretty valuable to all those concerned.
