BH-5/6 in KHXPC2700

[moho]

I just got in some 512MB sticks of Hyper X PC2700, i pulled the spreaders and heres the markings:
1st stick

V56948
0306 P01
D328DW-50

2nd stick
V56547
0306 P01
D328DW-6

Are all DW-6's BH6, and DW-5's BH5?

According to folklore (and the linked article, among others), 0319 and prior "DW-50s" are BH-5 and post 0319 are CH-5.

If your concern is that you have two different chips, I suggest the following:

One very important point to keep in mind is that in reality, BH-5 and BH-6 are the same chips, just binned to different speeds. Contrary to early thought, they were built on the same process and are identical. At the time the first DDR333 or PC2700 modules were being produced, DDR400 was not an option. Winbond binned and rated their chips to DDR333 speeds and labeled them as such (BH-6). Subsequently, after the introduction of DDR400, the newer chips were binned and labeled to DDR400 speeds.

The point being that those two chips are in reality no different than having two BH-6 chips or two BH-5 chips...they are the same thing for all intents and purposes (which is, of course...overclocking, right?).

See the linked thread for more on the topic of the process size and speed ratings.

awesome, i just now need to try to see how to overclock memory on my epox 8npa-sli. Very nice to know that they are identical chips :) specially for the $40 i paid for them.

There are some people out there that swear by the Kingston rebranded Winbond chips. Their claim is that these modules, which use only 54 soldering points/legs, as opposed to the normal 66, will overclock better because of those fewer legs.

Let us know how yours do.

My last set of KHX pc2700 was indeed BH-5 and overclocked like mad:D

Nice! just did a SuperPI 1M run at 240MHZ so far with 3.2V 2-2-2-5 :)
but this epox board doesnt have Dual Channel, so the bandwidth is limited :(
