BH5 or TCCD????

[ben rogers]

Hi all,

i recently bought some RAM that is called Geil One and has a W after it on the box it came in...I am wondering if this is TCCD or BH5 chips. Ive read that it is BH5 but someone on another forum said the W ones were TCCD, but I cant get mine to clock well at all (tccd meant to clock a certain amount on not much vdimm) my board has a low vdimm limit of 2.8v and I cant even get 220 stable so I am wondering if this stuff is BH5 and needs a lot of voltage to perform well with tight timings.

thanks for any help.

Maybe micron 5b-g ??

Beauty chips (2,5-2-2-5 up to 26xMHz and 3-3-3 up to 30x MHz) and all with 2,9-3,05V
Like 2x512 Crucial Ballistix PC4000 -Micron 5B G

Mine did that (tested 32M Pi on DFI NF4):
264MHZ @ 2,5-2-2-6-7-14-2-2-2-2 @ 3,0+0,03V
285MHZ @ 2,5-3-3-7-7-14-3-2-2-2 @ 3,0V
304MHZ @ 3-3-3-8-7-14-3-3-2-3 @ 3,0+0,03V
Working great with intell and AMD :D

thanks mate.

time for a new mobo probably a dfi ultra d to fully test out this rams capabilities.

afaik GEIL One only used TCCD and UTT BH-5. The W stands for the Winbond series with BH-5.

Geil One W == BH-5. Geil One TCCD is the name of the TCCD variant. There are no other variants.

You can sell that on ebay real good.

I cant even find any on ebay so it must be rare, quite lucky to pick this up I think.

What kind of voltage does it require to clock to 229MHz 2-2-2-5 or even 1.5-2-2-5? and what is it likely to top out at assuming I get the DFI Ultra D that allows high vdimms,, also what is the max vdimm adviseable to set with the stock head spreaders?

They will do around 270 MHz 2-2-2-5 at 3.4-3.5V, at least mine did :)

thanks - is that kinda voltage going to shorten the chips life at all or will it be ok?

[BigJoe]

A friend of mine was going 3.4-3.6V about two years on Corsair XMS with Winbond BH-6 chips.

AFAIK Geil gives a lifetime warrenty up to 3.8V but the ONE W aren't listed anymore on the Geil homepage.

[uOpt]

Yeah, the warranty was for 3.8, maybe 3.6V.

Problem is that your board's power management might not be happy :)

[Desert Igel]

A DFI with the jumper in high-voltage configuration should be happy about it, because the mosfet has to fry the difference to 5V.

Two sticks of 512Meg required about 2.96V to run without error at 230 after a lot of burn-in, one required 3.15V and higher drive strength (at least before burning in). My Buffalo CH-5 also required 3.15V to do it. Been running all four sticks at 3.4V (255MHz 2-2-2-5-2t) with a quiet 92mm fan over them (they don't crack ~39 degrees) for the better part of a year so far. I'm hoping that if they actually do crap out, it happens before "RAMPEC" successfully turns on the DDR2 rape switch later this year so'z I can have good reason to grab a Q6600/P35 and 2-4Gigs of D9 :D

I think it violates some U.N. charta or another to run Geil One BH with just 3V and 230 MHz :mad:

Check DFI as is not recommended to use the high voltage setting on the ultra D... You are better off using one of those adapters like the OCZ that I cant recall the name although I still have one around from my BH5 days.

[uOpt]

Uh? The whole point about these boards is that you can run these voltages natively.

Whether it is really healthy is a different matter.

Desert Igel, the important question is how much power is flowing, not what the voltage differential on the mosfets is. These are not just resistors.
