How well do the Winbond CH-6 chips oc?(updated)

[bgeh]

i just got 2 sticks of Kingston Value RAM 512mb PC2700 woth these chips
i do know that they are rated at 6ns, or 166mhz
but i do hope they'll oc like the BH-5 chips
so what are you guys getting with this chip?

 

[bgeh]

bump

 

[bgeh]

so does anyone know about these chips?

 

[LastRide]

Thugsrook thinks the BH-6 chips are the ones to get.All you can do is check it out and see for yourself unless someone that has the same as yours can testify.Since the memory varies its good to just try it and see what yours is capable of.

I got my Kingston-Winbond BH6 overclocked to PC3200 2-3-3-6 rock stable, at 2.5 or 2.6vdimm. It overclocks like a charm for a PC2700.

And now I'm testing it at 429MHz 2-3-3-6, seem almost reaching the limit.

 

[bgeh]

i can't test them currently
my KT266A board doesn't have a PCI lock, so i won't know how good the chip is
running them currently at 133MHz using aggresive timings
but tried Memtest86 and returned errors
and re-checked and they're actually Winbond CH-6 chips on it
so do these chips oc well?

 

[bgeh]

and 1 more question
what's the difference between the BH-6 and CH-6?

 

[LastRide]

I get the feeling the CH-6 probably isn't that good.

i know.
but on my mobo, all perfectly good RAM(0 errors in 24 hours in memtest86) get lots of errors

 

[LastRide]

I don't know what to say.Wait until your new mobo comes in I guess and check if you still having the same problem.Some people don't even memtest86 their ram and just assume its good.Running at tight timings with no errors is a hard accomplishment.You have to be fortunate to get a stck that does.Up your Vdimm voltage one and try again on memtest.If it fails bump it up another notch.I wouldn't go over 2.8vdimm myself,but 2.8 should be ok.Try 2.6,2,7 and 2.8 at tight timings.

so does anyone actually own these chips?

I've studied a lot about Winbond memory chips.

It seems that for first Winbond introduced AH chips, marqued as AH-6 for 6ns, after they introduced BH chips in 6ns and 5ns grade, the BH-6 and BH-5 chips.
As the BH-6 and BH-5 are very similar in overclocking, and as CH chips were introduced at the end of February in the Winbond datasheed, the "Revision C" of the Winbond memory chips could be the new king of the hill ! In 6ns and 5ns grade for now, we can assume that they will the new chip for the 4ns grade as the BH was for the 5ns.

So, just test by yourself. I'll tell my result for the Winbond AH-6 chips in 256Mo PC2700 Single Sided Memory Module :
184MHz at 2-2-3-6 - Idle Timer at Infinite - Refresh Rate 7.8us at 2.5V

damn.......that sounds very nice!!!
now i'm really excited to see how this chip will oc
merci!(thanks in french to english speaking people, like me, grabbed it from the dictionary)

Hum, I read again datasheets :
Winbond BH chips are manufactured in a 0.175um process technology
Winbond CH chips are manufactured in a 0.13um process technology

So, test quickly these modules !

but mine might have been the first batch of .13um, so maybe all problems might not have been resolved
anyway, can you pass me the datasheet

 

[bgeh]

does anyone have these chips
if so please tell me how they oc
i won't be able to use it till 2-3 weeks time, which is when i get all the other components

TIA

 

[Shimmishim]

sheesh... posting before you have parts

 

[Lizardman]

give it time and try it out for your self dude.

was too impatient. now the question is how can i last 3 weeks with watching the two sticks stare at me and begging me to torture them with a high oc?

never mind. i'm sending it to my friend tomorrow

 

[Mei]

Is there some news about real performance of these chips ?

 

[bgeh]

none yet
i'll get the results out most probably in 2 weeks time

My Corsair XMS PC2700 uses the CH-6 chips. It passes memtest86 11 passes, 10 loops clocked to 200MHz, 2-2-2-5 @ 2.7 Vdimm. Peace.

at last, some one finally posts results.
looks good to me
