PC3500 DDR with 865/875PE Chipset Boards??

Great ... sounds good ... I called Mushkin and they said no problem using PC3500 ... BTW,
what voltage did you have to use on the memory and which P4 and CPU voltage are you using?

I set it to +.1 which it think is 2.75,and i used a 2.8C with default voltage
of 1.525.
I didnt really push it to the max because i'm not using it to just se how
high it will go. If i were to try to get the max i would set the cpu volts
higher and the mem volts higher,but then i would have to use a lower ranm
multiplier like 1.66 and then the the memory wouldn't be as good.<!-- ~MESSAGE_AFTER~ -->

Not only just fine, but even much better.
Believe it or not, but some DDR 400 cas 2 rated modules do not work at
specified speeds !!! I had the experience with the very expensive Corsair
that refuses to boot at the speed mentioned on the package. Later I
discovered o their site that the speed is automatically set at cas 3 for bus
speeds higher than 366 MHz.
If I had purchased DDR433, it would have worked at 400 MHz at cas 2.
Another important point is the purchase of twin modules. Not paired modules
will NOT work at rated speeds at double DDR. Will cost you a lot of dollars
more, but no way around.<!-- ~MESSAGE_AFTER~ -->

Mushkin's web site only shows dual packs for use at 800 rated speed on Intel 865/875 and
nforce2 chipsets. I called them and they said that Mushkin dual packs are twins in so much
as that they were picked from the same assembly line at the same time and came off the line
right next to each other. Then they are tested to ensure the quality. Is that what you
mean by 'Twins'?

Yes, indeed. Twin is in fact the name used by Corsair.
But the process is identical: it' s just a (electronic) selection of modules
that fit perfectly together.<!-- ~MESSAGE_AFTER~ -->

Absolutely. You can run that ram at lower than it's rated speed, and it will
be perfectly stable. On the other hand, you wouldn't be getting all the
performance you could get.

I'm using cheap Buffalo Tech PC3700, which uses the same Winbond BH-5 chips
as the Mushkin PC3500.

On an Abit IC-7, I'm overclocking a P4C 2.4g to 3.3g at 275 fsb. The ram is
running 5:4 at 220 mhz, 2,3,2,6. 1.55V on the cpu, 2.8v on the ram. System
is very quick, Sandra buffered memory scores of 5840, unbuffered 2760. CPU
10K+.

The ram will run at higher speeds, but only if I relax the timings. Because
my cpu can't go much higher, this seems the best overall performance setting
for me. It's completely stable at this speed in Prime95, MemTest86, Sandra
burn-in, looping 3DMark 2003, etc. YMMV.

Contrary to what another poster said, you do NOT need matched ram to run
dual-channel. Two sticks of the same stuff is preferred, but many people
have been able to run different brands and specs dual. Those who pay extra
for a tested pair are merely buying a fairly expensive guarantee.<!-- ~MESSAGE_AFTER~ -->
 >> Stay informed about: PC3500 DDR with 865/875PE Chipset Boards?? 

Actually the Mushkin dual packs save you a few bucks (unlike other
companies) ... Their top end PC3500 Level II Back 512mb modules run $209
individually and $192 x 2 =$384 if purchased as a 1Gb dual pack.

And Newegg sells that same identical Mushkin "retail" dual pack for only
$329.

I called Mushkin about this and they said they discount the dual packs for
competitive reasons ... nice!

I just some Kingston Hyper X 3500 1 gig kit-( 2- 512 sticks )in a Gigabyte
KNXP 875 chipset board a nd they worked very good. $283 from google if you
dont mind the slow service. I used a 2.4 800FSB cpu with the memory running
at1 to 1 with the FSB.
It overclocked to 225FSB- 450mg mem with cas 2.0,6,3,3 latencies. It will
probably run at higher FSB but thats all i went to because i built it for
somebody else and they werent going to overclock any way.

i say bollox!

i`m running run of the mill twinMOS pc3200 2x 256mb, non matched on amd
based nforce 2 in D-DDR format. not only can i run in D-DDR, and overlock
the fsb higher than DDR400 spec (upto ddr412), but i can run at 3-3-2-2.

i cant see how MODULES can be the problem when not running matched pair and
D-DDR. PC3200's are made for either amd or intel based, and all i can say is
that intel must be very picky about the ram if this is the case.

Yes this the case sometimes,you dont have to buy matched sticks of ram,but if
you are buying 2 new sticks why not?
When you buy a twin pack you are getting 2 of the same exact sticks of ram,
granted Corsair is high,but Kingston sells a twin pack ( meaning both sticks
are exactly alike ) and both are tested is a working motherboard to ensure they
will work as pair.<!-- ~MESSAGE_AFTER~ -->

And Buffalo Tech uses exactly the same Winbond BH-5 chips as the Mushkin
PC3500. Without the fancy heatsinks NewEgg sells a 512-meg stick of PC3700
for $99 -- less than half the price. It's nice that Mushkin discounts them
in pairs, and they have a great rep for reliability and service. But I
wouldn't call it a bargain.<!-- ~MESSAGE_AFTER~ -->

I did noy say that you need matched ram to run dual DDR, but only that you
will not be able to run them at optimum speed. What I mean is that you will
probably never succeed to run DDR400 cas 2 at those speeds if the modules
are not paired. Or the speed will automatically be lowered to less MHz, or
the modules will only run at cas 2.5 or 3, or your system will not boot. I
say probably, because you could always be (very) lucky and have paired
modules by accident.<!-- ~MESSAGE_AFTER~ -->

And once again, I say balderdash. Ram should run at it's rated speed,
whether or not you run in dual channel and whether or not somebody stuck a
label on it that says it's a matched pair. If you buy two sticks of PC3200
CAS 2 and it doesn't run DDR40 at CAS 2, you should return it.

I know that running one stick of PC2700 CAS 3 and one stick of PC3700 CAS
2.5 is not a great idea, as you will have to run at the slower speed if you
can get it stable at all.

But if you buy, say, two sticks of Crucial PC3200 CAS 2.5, you should have
no trouble running it dual-channel at its full rated speed. If you can't,
you've either misconfigured the system or gotten a bad stick of ram which
should be replaced.<!-- ~MESSAGE_AFTER~ -->
