A performance issue

I have come into possession of a 64MB PC100 DRAM. My computer currently has
128MB PC133 DRAM. Running W98SE.

Can I run both DRAMS at 100MZ without damaging anything? If I can't will I
see a performance boost or degradation by setting the bus to 100MZ and
running both DRAMS?


Thanks,
Dan Hacker

First: there isn't enough information to answer your question from what you
supplied.

Your processor [speed and type] and motherboard [model and BIOS or at least
the computer manufacturer and model] along with the actual attempted memory
manufacturer and IDs are necessary.

Pending that information:
The general recommendation is to not mix speeds /CAS of memory IF any chips
are made within the last three [to five] years without first checking to see
if they can support different clock speeds and at what CAS/RAS they support
that speed.

Likely you may not be able to lower your present FSB [front side bus speed]
due to your processor requirements unless you have a split/dual bus
configuration [not likely] though you may be able to downgrade your
processor through the BIOS, though that would defeat the purpose. You MAY
however, be able to overclock [per the module rating] the 100 to 133 if we
are supplied with the information.

Please post your information so we can help determine your potentials.

Hi Dan,

What motherboard is it, or if it is a major name computer what brand and model is
it?

Yes, you can usually do that.
However, why don't you try it and see if the performance really does increase.
Some motherboards do not work well with a processor (cpu) running at a different
freq than the DRAM.
ie: cpu on a 133MHz FSB and the SDRAM on a 100MHz FSB.
With ram so cheap, why not just buy what your motherboard mfg recommends?
PS: If you have to set your cpu FSB to 100MHz to use the ram, your performance
will be noticeably worse.

If your PC100 DRAM is high quality, it may run just fine at 133MHz.
Mine did.
PS: I used it in combo with a stick of PC133 DRAM.

I may be wrong, but I was told if you mix speeds, you were automatically
limited to the slowest speed. I'm mixing 133 and 100, and what is more
important to me is the added memory, not the speed. I don't believe one
could actually see the difference between 100MHz and 133MHz, but the
additional memory, yes. The biggest consideration in my opinion, is whether
or not the mis-matched memory will "play well" together.

Can your motherboard/chipset cache more than 128MB of RAM? If not,
then you may actually experience a slowdown when you add your 64MB
stick, even if you can get it to run at PC133 speeds.

Please remove one 'i' from my address when replying by email.

Not really true if you set the FSB speed to 133MHz for the ram.
If you let the system do it automatically, it will usually revert to the speed
of the slowest ram stick.
Some of the high quality 100MHz ram will easily run at 133MHz or higher.
Generally, mixing ram speeds and sometimes even CAS rating and brands is not
recommended for optimal success.
However, if he wants to try it, then he will have the answer.
If it gets into a non-boot scenerio, usually just removing the slower stick will
correct the problem.
If it does not and he cannot get into the BIOS to set the ram speed manually, he
will have to shut down and clear the BIOS using the 'jumper' to clear it and
then reboot.
If he has to run his cpu at the slower 100MHz FSB also, he will be slower, even
with the addition of more memory.
PS: running the memory at 133MHz or 100MHz would not show a major difference in
his system. The cpu FSB speed is much more important in terms of performance
improvement.

Along those lines; I have tried to address those potential issues
sufficiently through several discussions in this group:

Short, yes, the lowest "supported" CAS and/or speed:

Xref: TK2MSFTNGP01.phx.gbl microsoft.public.win98.gen_discussion:823421

Xref: TK2MSFTNGP01.phx.gbl microsoft.public.win98.gen_discussion:823473

Xref: TK2MSFTNGP01.phx.gbl microsoft.public.win98.gen_discussion:823477

tried PC133 memstix - DBLBUFF & IFSHLP went corrupt/missing 02-22-06

Xref: TK2MSFTNGP01.phx.gbl microsoft.public.win98.gen_discussion:807307

Xref: TK2MSFTNGP01.phx.gbl microsoft.public.win98.gen_discussion:807352

The summary is don't try this anymo

The days of switching "any old memory" with "any old memory" or mixing such
went the way of abilities to blindly overclock processors [though that
ability with memory lasted for several more years].

As memory manufacturers became more productive at module creation, and
specific processor/mother boards began to require specific and limited
modules; the ability to use that memory in the old fashion of "trial and
error" or reliance upon supposed new automatic BIOS recognition when
mix/matching went the way of the dinosaur when attempting to deal with newer
controller chips in a mixed environment.

New module "controller chip" designs coupled with better QC apparently
allowed the manufacturer to essentially lock the supported speeds and
CAS/RAS available/or for which they could be used [Think Intel's better
manufacturing and QC allowing them to lock processors. SEE NOTE * ]. Mixing
those essentially locked modules, has been found to cause corruption issues.
So the long held belief that CAS2 100 could easily replace or work with 133
CAS3 was/is no longer viable. Moreover, if CAS3 100 [which was/is the most
prevalent produced] is attempted at 133 at ANY CAS/RAS, numerous issues
pop-up. They may pass POST, but when actually used by the OS, the errors
abound. The same has been found true, at times, with 133 CAS2 attempted at
100.
All the major manufacturers openly supported, CAUTIONED, and specifically
noted on their websites and in their adverti$ing, that one must carefully
match the BIOS support, processor and the memory, as failing to do so,
likely would cause failures.
One can still find smaller manufacturers that create multi FSB/CAS support
modules, though that's likely due to the controller chip they used, rather
than any real intent.

*This change over related directly with the Asian memory crash and burning
of a memory chip manufacturing plant. The investors and the "BANKS" demanded
updated manufacturing techniques from the survivors. Siemans apparently
implemented this around the same time period.

First: there isn't enough information to answer your question from what
you
supplied.

Your processor [speed and type] and motherboard [model and BIOS or at
least
the computer manufacturer and model] along with the actual attempted
memory
manufacturer and IDs are necessary.

System
Processor
Model : AMD Athlon(tm) XP

1.5-1.65V
Speed : 1.25GHz
Manufacturer : MICRO-STAR INTERNATIONAL CO., LTD
Model : MS-6378
System BIOS : 01/17/2003-8361-686B-6A6LMM4SC-00
Chipset : VIA KT133/A
Bank 0 : 64MB SDRAM 2-2-2-0CL
Bank 2 : 128MB SDRAM 2-2-2-0CL
Shared Memory : 8MB

Memory Module 2 : SpecTek 128MB 4x(16Mx16) SDRAM PC133U-333-5412 (CL3 up to
133MHz) (CL2 up to 83MHz)

Likely you may not be able to lower your present FSB [front side bus

due to your processor requirements unless you have a split/dual bus
configuration [not likely] though you may be able to downgrade your
processor through the BIOS, though that would defeat the purpose. You MAY

Front Side Bus Speed : 2x 100MHz (200MHz data rate)
Maximum FSB Speed / Max Memory Speed : 2x 133MHz / 1x 133MHz

however, be able to overclock [per the module rating] the 100 to 133 if we
