Intel Saying Good-bye To RDRAM?
With COMDEX Fall
around the corner, mid-terms in full swing, and anticipation of new and exciting technology releases
in November this is a really exciting
time! I'm personally looking forward to Microsoft's Tablet PC on Nov. 7th; and
we're already sussing out a few devices to review. To get the
dirt on the new Tablet PC as it unfolds I recommend you check this.
For companies like Transmeta, the
Tablet PC should really emphasize the Crusoe's long battery times - but we
speaks about Intel & RDRAM this week along with some words on dual channel
DDR, so make sure you read The High Tech Low Down. Last time we promised you Radeon 9700 reviews, and in
today's PCstats.com Newsletter we have a Radeon 9700 Pro from
Crucial on the block. Actually, it seems we've gone a little bit heavy on
videocards this week, for we've also tested the MSI GF4MX440-8X and Prolink GF4 MX440-8X cards. I think a good tech
diet should consist of videocards and
memory; and with DDR firmly entrenched I've included an excellent review we first posted
about a year ago. The review covers PC2100 DDR and also contains a good synopsis
of the changeover, and explanation of what DDR really
means. Definitely worth the read!
Jumping back to the present, Corsair have just released
some very tasty XMS3500 DDR. We have the review right here, along side
a look at a new technology Kingston memory is calling EPOC. Be
sure to check out Colin's Weekly Tech Tips if you game on Windows XP.
Until next week, keep those email's coming and we'll do our best to answer
your questions. If you haven't yet tried out Intel's Tech Wire you might want to now.
Unlike the Radeon 8500LE which was a good
choice for value oriented users, Crucial is targeting high-end gamers with
their Radeon 9700 Pro, which retails for about $369USD. To top things off, anyone who has bought
memory from Crucial knows they have an excellent level of service and
support!The Crucial Radeon 9700 Pro has all the goodies
that come with the standard Radeon 9700 Pro. It uses the same ATI R300
core which has 107 million transistors built on the 0.15 micron
manufacturing process. The card is fully DirectX
9.0 compatible , as well as being
an 8X AGP part. The 128MB of memory on board uses a 256-bit memory
interface which gives an amazing peak bandwidth of over 20GB/s!
Like every new technology standard to arrive, "8X AGP"
has eagerly been picked up by videocard manufacturers; if your videocard
or motherboard isn't 8X AGP compatible you're using old tech - and who
really wants to have old technology? Today we're going to check out MSI's
newest addition to their family of video cards, the GeForce4 MX440-8X
based videocard. Will 8X AGP breath new life into the old DirectX 7 based
GPU? I think so.

RDRAM, DDRAM, SDRAM
is certainly the new catch phrase when it comes to motherboards and videocards these days. Since
SiS and ATI both enjoy the 8X AGP spotlight it would be a
little naive to expect Nvidia to sit back and stay out of the
party. Today we will be reviewing the Prolink PixelView GeForce4 MX440-8X; the videocard uses
the new tweaked NV18 (MX440, 8X AGP compatible) GPU, and is backed up by
TSOP-II 3.6ns Samsung DRAM.
Prolink is targeting the gamer on a budget with the PixelView GeForce4
MX440-8X because the card is probably one of the fastest
GeForce4 MX's out there. Prolink clocks the core of their card at a full
300 MHz up from the 270 MHz most other MX440/MX440-8X's are clocked at.
The memory is clocked at an
amazing 550 MHz, again up from the
usual 400 MHz of most other MX440/MX440-8X's!
Read the Review
[This review, originally posted June 2001 has a
very good synopsis of DDR, and how the switch from SDRAM came about. We've
been getting a few questions on the matter lately so I'm recommending it today.
In the last few months, the PC industry has been witness to some very
exciting developments. Processors that were once
considered fast (550-900MHz), have been
supplanted by small squares of silicon which can easily run well over the
'magical' threshold of 2.0GHz. Still newer processors are on the drawing
boards of chip designers which by the end of this year are expected to
break the 3.0GHz+ barrier!
DDR RAM timing for CAS2 DDRAM. Note
the vertical dashed lines which indicate an access of the memory.
There are two per clock cycle (T0-T1), whereas SDRAM has only
MEMORYCAS Latency (CL) is the delay between the
registration of a read command and the availability of the first
piece of output data. CAS latency is measured in clock cycles. This
particular timing diagram represents SDRAM with a CAS latency of 2.
In this example a read command which is registered at T0 (Time=0)
and will not be valid until T2 (Time=2). Essentially, the lower the
CAS latency the better - this holds true for both DDR and
DDRAM (Double Data Ram)
evolved from the need to search out an alternative to SDRAM to free up
this pressing bandwidth limitation.

EPOC Technology for Memory
Corsair XMS3500 CAS2 DDR Memory
EPOC was developed with server memory in
mind. Servers are very crowded devices and there isn't much room in a 1U,
2U or even 3U rack mount system for many DIMM slots. DIMM slots are where
the DRAM gets clicked into place, and typically there are four on a
motherboard. Typically memory modules max
out at 1GB
- and since it
is very, very expensive to achieve this level of memory density using 16
individual TSOP-II chips (Thin-Small Outline Package), manufacturers use a few tricks.
is well known for producing some of the
highest quality DDR memory there is, and unlike some other
manufacturers which share the same distinction, Corsair's memory is
readily available and easy to get a hold of. Now, we recently looked
256MB XMS3200 CAS2 DDR memory module and were quite impressed
with what we saw. The question on the table today is whether the
just announced Corsair XMS3500 DDR memory would fill
the shoes, and offer even more.

Faster FPS Gaming with Windows XP!
WindowsXP is a great OS, but one problem I find
that bugs the hell out of me is Mouse Acceleration. It's especially
irritating when I play FPS games. Luckily there's a simple fix for
this. Click the Start Button, go to Run and type
From there go to HKEY_CURRENT_USER -> Control Panel -> Mouse folder. Find the SmoothMouseXCurve: and SmoothMouseYCurve: binary value's. Here under the binary SmoothMouseXCurve you'll want to change your value's to look like this...
00 00 00 00 00 00 00 00
00 a0 00 00 00 00 00 00
00 40 01 00 00 00 00 00
00 80 02 00 00 00 00 00
00 00 05 00 00 00 00 00
And change the
values to this...
00 00 00 00 00 00 00 00
66 a6 02 00 00 00 00 00
cd 4c 05 00 00 00 00 00
a0 99 0a 00 00 00 00 00
38 33 15 00 00 00 00 00
After making those changes, reboot your computer. Now load up your favorite FPS game and you should notice you can 'frag' a lot easier!

|The High Tech Low
Months after the introduction of
VIA's KT333 chipset (supporting DDR333),
Intel has decided to officially validate the memory
technology for its own i845 family. With the release of the i845PE
and i845GE chipsets, Intel also comes close to
eliminating any reason to pick up an i850E board with RDRAM memory.
Yes, SiS' R658 may breathe some life back into
Rambus' brainchild, but it would seem that RDRAM may very well be on the way out.
Having axed RDRAM from its roadmaps,
Intel is focused on moving from a single channel to
dual-channel DDR memory configurations. Beginning next year,
will offer the "Granite Bay" chipset with said dual-channel support, aimed at the workstation market.
Although DDR400 is available from many
manufactures, DDR333 remains the favorite. NVIDIA
claims that the nForce2 chipset performs best running synchronous
front side and memory busses (in other words, 333/333MHz).
Similarly, I've seen very little improvement moving from
VIA's KT333 to the newer KT400 chipset. In order to
achieve stability with DDR400 memory, many motherboard manufacturers
are having to soften memory timing, resulting in reduced
performance. Perhaps we'll have to wait for a JEDEC
memory standard before DDR400 becomes a more viable option.
Until next week…
Meet the Radeon 9700, motherboards galore, and.... oh we can't tell you yet ;-)
