As what many have mentioned here, it's the chipset that matters on how far the rams can go basically.
The other factors would be the PCB Layer count. Many value rams tend to use less layer PCBs while HP Rams have higher number of PCB layers.
I'm not too sure specifically how will it help in overclocking, but from what i heard, the higher the number of layers, the better the rams will withstand extra voltage pumped into it.

FP-Y5 doing 1300, thats only 1 revision of it if i've not mistaken. Used to know the specific revision when i was still selling rams.
While for the team values, yes i can confirm such rams do exist. I have a pair which can do 1200Mhz at 5-5-5-15 2.1v.
The team values were relabeled, so no way of telling what chips are those under the disguise, but best bet will be either D9 or Promos. From the shape of the chips, they do resemble D9, but the pain it causes when i try to run it on CL4 indicates the other way round.

There are many D9s out there.
Stating only D9 is very general.
D9DPN will not clock as good as a D9GCT/D9GMH/D9GKX.
Only D9Gs are known to be good at clocking.

So please beware when you try to purchase rams and only ask if they are D9s. D9s are everywhere, but not GMH,GKX and GCT.
Please also take note that the current Crucial Ballistix and Ballistix Tracers which are available for a good price does not use D9G. D9Gs will not come at such a price.


Ya, Rm300 per pair confirmed D9GMH.
Slap HR-07s on them and they fly.
Some will be willing to pay for them considering the fact that, it's guaranteed D9GMH and you won't need to void your warranty to check it out.
While for other HP rams, you'll need to rip off your Ram Sink which in most cases will void the warranty.

Well, it very much depends on the ram chip itself rather than value rams or performance rams.
I had a pair of Team Value Rams which did 1200Mhz 5-5-5-18@2.1v.
And i've seen a lot of Crucial Values which comes with D9GMH chipsets doing pretty well.
It takes a lot of effort in finding a good pair of VR though. Those Kingstons which come with D9GMH/D9GKX are no longer seen on the market.
There are gems everywhere actually, just how u manage to discover it and unleash. Dun be surprised that under the relabellings, some of those are actually GMH/GKX.
