Hi,
=20
I am researchng the parts for a new machine (AMD 2500+ ABT NF7-S) and ha=
ve
heard good things about TwinMOS. . . .
=20
But which sticks should I choose? I intend to try for a 400MHz FSB
overclock at
least,
=20
TwinMOS PC3200 DDR-DIMM 256MB w/Winbond
- 32M*8/16chip, 184-P (for DDR-PC400MHz)
=A344.17
=20
TwinMOS PC3200 DDR-DIMM 256MB CL2
- 32M*8/8chip, 184-P (for DDR-PC400MHz)
=A346.21
=20
TwinMOS PC3700 DDR-DIMM 256MB CL2.5
- Memory 184-P (for DDR-PC466MHz)
=A347.97
=20
People have spoken highly of the TwinMOS/Winbond but I can't tell what Ca=
s
it is?

I've just bought some new parts to upgrade my pc last weekend: a Barton=20
2500+, the Abit NF7-S and 2 sticks of Twinmos 256 MB PC3200 (they came=20
in 1 package and are tested together like the Corsair Twinx).

I've flashed my motherboard to the latest bios and overclocked the cpu=20
to 10x200 so that it runs in synch with the memory. After that I tried=20
to use some faster memory timings than the standard 8-3-3 and CAS 2.5,=20
but without success. As I'm new to the world of overclocking, I'm not=20
sure if there's something that I might have overlooked or if the sticks=20
can't be pushed any further. I didn't change the memory voltage though.

Maybe this answers part of your question?

Hi SyntaX,
yes that is good info. So you opted for the CAS 2.5 TwinMOS. I think you
need to *relax* the memory timings if you want to go higher than 3200 specs.
I'm kinda thinking that Cas2 (over 2.5) would give better results. What is
the XP rating of your Barton when overclocked?

Yep! that's the one [make sure it's CH5 and not CH6]
2.5 [stated] - decent makers always understate - ****e is usually
overstated

Hi,
CH5 and not CH6? what the heck is that, also where does it *state* the
TwinMOS/with Winbond s Cas2.5?

It's just the chipset CH5 is supposed to be a better performer than CH6
because the SPD timings were more aggressive.

Hi,
thanks for the reply and useful links. That twin pack looks cool and a good
price also. I'm left wondering about the PC3700 now. ..

I choose the Twinmos because they told me in the store that it has
Winbond chips and that these would allow the sticks to run at CAS 2
(which is of course faster than 2.5).

I'm not overclocking the memory, just the FSB and cpu (which at 10x200
gets identified as a 2600+) so the memory and FSB run in sync. Still I
cannot get the memory timings lower. I assume I can raise the voltage
for the memory, but that prolly wouldn't change the timings (and I'm a
little afraid of harming my new system).

There is almost always a benefit [overhead] in getting the higher
batch[s] if you can pay the xtra money!

Hi,
thanks for that link, just what I wanted to read. So then I figure that the
TwinMOS PC3200 (Winbond CH-5) is the DDR I will opt for. I didn't realise
that this PC3200 had so much *headroom*. . .cool. Now just need to find a
U.K supplier that lists CH-5 winbond twinMOS.

Thanks again all,

"" 10:50am [1st July] - Our Winbond major on 3rd memory just arrived and
the DDR400 modules are using Winbond's CH-5 chips which are highly
sought after by overclockers due to their ability to hit high front side
bus speeds whilst still using aggressive memory timings. Check out this
review by vr-zone who were able to achieve 244FSB with timings of 2-3-2-
5 with Winbond CH-5 based memory. In stock and ready to ship.""

Hi,

Doh! I checked OC.uk and had seen that a few days ago, but when I went back
to look again I was checking the TwinMOS page and couldn't see it (forgot
about new Winbond page). I thought OC.uk had *refreshed* their TwinMOS page
and removed the CH-5, CH-6 tags :P

Thanks again for the heads-up I thought I was going a bit loopy,
