OT: CPU compatilbilty ...

[RJK]

My 2nd, (old), pride and joy has a Asrock Conroe 865pe motherboard in it,
and I just robbed it of its' Pentium D 935 cpu, !

....and put it into a friends HP Media Center PC, whose Pentium D 2.8ghz cpu
died - after it mysteriously cooked, just 3 days after being taken to a PC
shop where they replaced the PSU with the cheapest one they could find - by
the look of it ! Anyhow, after the cpu suspiciously fried, and they took it
back to that shop, and were told that it now needs a new motherboard, and
cpu, and possibly memory as well !
....then they remembered me - ...who has just sorted it out for them, and
they are now the proud owner of my D935 3.2ghz cpu ! (there was nothing
wrong with motherboard or ram btw

The "computer" shop referred to above, is located in Burnham-on-Sea,
Somerset, UK !!! ...let's hope there's more than one computer shop in B-O-S
, or people might guess which one I'm referring to, ...what a shame !

Anyhow, I digress, ...as usual !

Referring to http://www.asrock.com/mb/cpu.asp?Model=ConRoe865PE 's cpu
support list for my old board, it doesn't seem to support many of the
"newer"
Core 2 Duo's e.g.
http://www.ebuyer.com/search?limit=50&store=2&cat=22&subcat=1770&sort=pricelow&page=1...is it just that Asrock haven't bothered to update that list, or would oneof the 800fsb cpu's, (not on the Asrock list), simply not be recognised bymy old Conroe's bios ?any help appreciated,regards, Richard

Your board is likely limited to FSB800 or FSB1066 processors, so FSB1333 would be
out of the question. The chipsets of that era, were designed for FSB800, and
FSB1066 operation is via overclocking past the regular chipset speed limit
(it also messes up how the RAM works, and the requirements on the RAM, due
to the chipset divider issues). An FSB1333 processor would be a bit too much
for that. You could use an FSB800 processor and overclock it, or an FSB1066
processor at its stock speed.

I expect a number of newer processors would meet the FSB requirement. There
are still processors available with FSB800 or FSB1066. The problem is, that
Asrock has stopped putting the effort into shipping new BIOS files. The
last BIOS was released 4/27/2007. The BIOS may take a look at a newer processor,
and not complete POST. There is no way to predict what will happen, if you
use a processor which is not on the chart.

I suggest you use a search engine, plug in the name of your board, plus
the name of a newer processor. For example, I tried ConRoe865PE and E4700,
and found this. Notice the BIOS release is listed as 1.71A. And that
means, somewhere out there, someone has hacked the BIOS and is doing
stuff. (I got an "improved" BIOS from Germany, for my Asrock 4Core family
board, so there are people who do stuff like that.) The last official
release is 1.70, so when you see 1.71A, that means a hacker did it.

http://www.behardware.com/myocdb.com/fiche20256.html

So get out your search engine and go to work. You've got a
job ahead of you, to determine what the enthusiast community
has done with the board.

What you'd be looking for, is FSB800 or FSB1066 processors, so I
wouldn't bother searching for anything FSB1333 from this list.

http://processorfinder.intel.com/List.aspx?ParentRadio=All&ProcFam=2558

In this thread, someone is using ConRoe865PE and E5200. There is no
detail as to what BIOS they're using. That is a 45nm processor.

http://www.silentpcreview.com/forums/viewtopic.php?p=354183

The E5200 is in this list. The E5400 would be the most worthy of
those ones, in terms of a high stock clock.

http://processorfinder.intel.com/List.aspx?ParentRadio=All&ProcFam=2841

An E5400 is $90. But before you buy one, you're going to need to
find a private forum, where they're hacking the BIOS. I have
a suspicion that may help. Your project will have an element
of risk (not in terms of damaging the processor, but in terms
of not getting the board to POST and so on - so you may need
to do some BIOS work, using some other compatible LGA775 processor).

E5400 $90

To help you out, the BIOS may be at the link at the bottom of this
page. V1.71a. Good luck... If the BIOS chip is socketed, you
could go to badflash.com, and order a BIOS chip with that
burned into it (change out the old chip, plug in the new one).
Or, use some old cheesy Celeron LGA775, to help
you do the flashing, then install the new processor.

http://www.pctreiber.net/datei_download_2472.html

Fortunately for me, my processor already worked with a stock
BIOS, so I was able to flash in a hacked BIOS without a problem
on my Asrock board. My hacked BIOS, fixes EIST so it works on
my board. That makes the processor run cooler at idle.

I have googled and found someone using a Core 2 Duo e7200, and whilst all

always wanted a D965 but, they're very rare), for the time being,
....and maybe ebay for a Core 2 duo that is on
http://www.asrock.com/mb/cpu.asp?Model=ConRoe865PE 's cpu support list, but,
even the "newer" older ones have already got too old !!

Oh my goodness, I've just bought a Stk 775 Intel Pentium Core2 Duo E6300 :-
http://www.cpu-world.com/CPUs/Core_2/Intel-Core 2 Duo E6300 HH80557PH0362M (BX80557E6300).html
...and am now confused by fsb frequencies, above specs. indicate that fsb on
board needs to be 266mhz, and then something gets quad-pumped up to 1066 !
....now does that mean that my lowly 4x512mb Corsair PC3200 will actually be
running at 133mhz/(266ddr),,,, and then it gets quad-pumped, or is the
actual frequency on the board 266mhz, and if so will my 4 old sticks of
ddr400/200mhz actual mhz, be able to cope ?

....haven't tried to fit cpu yet, it hasn't arrived yet, and haven't checked
bios revision you, ..mind you that'll be hard 'cause there's no cpu in it
atm !

The Conroe865PE manual says at FSB1066, the memory runs at DDR400.
By my math, I'd expect DDR354 (1066/800 * DDR266). Once you get
it running, you can use CPUZ to see what actually happened, and
whether the ratio is actually available to make it run at
exactly DDR400.

If you didn't keep track of the BIOS release, you'd just going
to have to give it a try. There are two different E6300 running
at 1.86GHz in the Asrock CPU table, each with a different minimum
BIOS release. (Check the top of the BIOS chip for a sticker. The
original release number may be noted there. If you've flashed
it, it would likely be at some higher release now.)

If it won't POST, then either you could use badflash.com or a similar
site, and purchase a replacement BIOS chip and plug that in. Or,
you could purchase a Celeron LGA775 of some sort, as a temporary
processor to use while you flash the BIOS to the latest release.
Then plug in the E6300. So there are a couple ways to update
the BIOS. And the badflash.com option, is only viable if the
BIOS chip is sitting in a socket and is removable. If the BIOS
chip is soldered to the motherboard, then replacing the chip
would require soldering skills. So the "cheap Celeron" for
flashing, is the safer alternative.

Many thanks again Paul,

Earlier today E6300-1.86ghz cpu arrived and I fitted it Conroe865pe
motherboard - to see what would happen ! ...Conroe865pe bios is v1.7
btw.
At boot, bios reported a 1.4ghz cpu, not the actual 1.86ghz.0.065
micron model that it is. So after playing with bios settings and
tweaking them several times. At one point, (perhaps stupidly), I set
the jumper "FSB1" motherboard jumper from short pins 1&2 (FSB
533/800mhz) to short pins 2&3 to select (FSB 1066mhz), and things went
steadily downhill, until it would not even boot to bios screen. I
even began suspecting that something had died, perhaps even AGP
card ! Even after clearing CMOS settings, ...still no sign of a bios
screen !

Suspecting that bios could not cope with E6300, even after clearing
CMOS, and that I would have to get a Pentium D (800mhz fsb) cpu back
in there to recover, I rummaged on ebay and just bought a Skt. 775 D
930 !
Then I sat for a while and pondered on having to wait for a day or so
for it to arrive by post, and just for something to do, I fitted the D
820 from a friends PC, (that I was sure had died - mentioned earlier
in this thread), and just before fitting it I gave that "dead" D 820
underside gold contacts a gentle wipe with a piece of black cotton,
(something of course one would never normally do), and was astonished
to notice a faint white residue came off onto the cloth !!! Now,
whilst working on the "friends" PC mentioned earlier, I had noticed
that a white coloured h/s compound had been carelessly, nay, slapdash-
edly - smeared onto to cpu lid - on top of previous "grey" coloured
heatsink compound that had obviously not been cleaned off. ...anyhow,
IT BOOTED UP without a glitch ! Now, whether that electrically
"insulating" effect of a very thin residue of heatsink compound had
been applied intentionally, or just carelessly, I suppose I'll never
know ! However, it means that I'm left in the annoying position of
knowing that I've lost my beloved D 935 cpu into a friends PC, and
I've bought an E6300 that I don't know how to get running properly,
and I've just bought a D 930 that I possibly don't need ! Or should
I console myself that the D 930 from ebay, that hasn't yet arrived
yet, has "Enhanced SpeedStep technology" on it, but the D 820 from my
friends PC does not !

I digress again !

Now that I’ve been able to get my 2nd PC up and running again with
that D 820 in it, how do I prepare it for a E6300 ?
During my earlier failed attempts, the “Auto” fsb setting, in bios,
was showing a greyed out “266,” and the bios label for that setting
was “Actual FSB” so was this far too high for the ddr400/pc3200
modules (200mhz actual/on board) currently on the board ?
Do I really need to set that “FSB1” jumper to 1066mhz – and then
perhaps change that “Auto” fsb setting in bios to “Manual” so that I
can wind it back down from 266mhz to, say, 200mhz ?
Is there a PC-???? Model of 184 pin memory that actually runs at
266mhz ?

I don’t understand why the Conroe865pe motherboard manual says that I
must have DDR400 modules fitted, (which I have), in order to use the
1066mhz (overclock) function, when the bios Auto-detects the cpu fsb
as 1066 and sets a board fsb frequency of 266mhz – which must be too
high for the pc3200/ddr400 – 200mhz-on board, …modules ? !

…phew, ..about to rummage in Conroe bios again, and maybe refit
E6300 !

Land grid array pads, are not designed with contamination in mind.
They don't like heatsink paste smeared on them. Even sweaty fingerprints
may eventually cause problems, so you should never touch the gold
on the bottom of the chip. There is no guarantee, that if you use
solvents and cleaning clothes, that all residues will be removed.

That is one reason, the Intel installation video, shows the installer
using gloves during installation. The gloves help prevent salty
fingerprints on the gold. The gloves also happen to be antistatic.

http://www.intel.com/cd/channel/reseller/asmo-na/eng/100617.htm

The FSB1 jumper on the motherboard, is only to be used if you're
overclocking a lower FSB processor, to FSB1066. You don't need to
use if, if you want the processor to "Auto" detect. Set the jumper
to position 1-2, then the BSEL contacts on the processor, will tell
the motherboard what speed to use. Position 1-2 would seem to be
the "Auto" position, that lets the CPU logic signals, help set the
speed.

For the E6300, the normal multiplier is likely 7x. 1866MHz/266MHz = 7.
Now, you're seeing 1400. If the bus speed was incorrectly determined,
then 1400/200 = 7 makes sense. That tells you the FSB is FSB800
(CPU input clock = 200MHz, quad pumped bus runs FSB800). Once you
correct the FSB1 jumper, the processor should ask for 266MHz via
its BSEL contacts.

The 875/865 family of chipsets, has a number of memory ratios available.
The initial tables (like the table in my P4 motherboard manual), may
list three ratios available for an FSB800 processor. When the Asrock
design runs FSB1066, they could still have at least those three
ratios available to them. The lowest ratio, should cause the RAM to
run at DDR354 (it means the other two ratios, would result in the
RAM running too fast, so those other ratios are not offered). That is
the value I calculate, which your DDR400 RAM should handle with ease.
You can use CPUZ from cpuid.com, to verify the setting, once you've
booted into Windows again.

Have you verified the BIOS version yet ? Did you look on the screen
during POST ? If the board will POST with some processor present, you
may be able to flash upgrade the BIOS. If the BIOS is already up to
date, then nothing further needs to be done. You want a revision of
BIOS, meeting the minimum requirements listed in the Asrock CPU chart
for the stepping of E6300 you purchased. (The stepping can be determined
from the SLxxx code on the top of the processor. Plug the numbers
into processorfinder.intel.com for more info.)

At least you have *some* processor to work with, so you should be
able to finish this adventure now.

during POST ? If the board will POST with some processor present, you
may be able to flash upgrade the BIOS. If the BIOS is already up to
date, then nothing further needs to be done. You want a revision of
BIOS, meeting the minimum requirements listed in the Asrock CPU chart
for the stepping of E6300 you purchased. (The stepping can be determined
from the SLxxx code on the top of the processor. Plug the numbers
into processorfinder.intel.com for more info.)

At least you have *some* processor to work with, so you should be
able to finish this adventure now.

Many thanks, muchly again !

1). This morning I fitted D820 to get PC to boot, then, set "CPU Host
Frequency" to Manual | and wound the 266 "Actual Frequency setting (Mhz)"
back to 200.
2). Set Jumper FSB1 to short pins 2&3 1066 fsb, checked that "Actual
Frequency (Mhz)" was Manual | 200. It has booted up ok like this before,
....boot-up is ok, ...CPU-Z | Memory tab shows that "DRAM Frequency is
133mhz. ....also a greyed out "7" 'multiplier' is showing.
( If I toggle "CPU Host Frequency" to "Auto," "Actual Frequency (Mhz)"
changes to a 'greyed out' 266',
....and if I let it boot up like that, i.e. with a 'greyed out' 266' ,XP gets
into trouble.)
("Advanced" | "Chipset Configuration" bios screen always shows a greyed out
"DRAM Frequency [200MHz (DDR400)] btw)

3) Took out D820 and put in E6300, , oh blow it! ...I've set "CPU Host
Frequency" to Manual | and set it to 233, ...afraid to leave it on the Auto
greyed out 266 or manual 266, booted up, and CPU-Z | Memory tab shows DRAM
Frequency at 155.3 | FSBDRAM 3:2 ...boot-up/XP load OK.

4). Just set "CPU Host Frequency" to "Auto" | grey 266 showing, and Windows
cannot load - DOS screen with "* missing or corrupt" type message (feels
like corrupted RAM),

....will now wait until Kingston 2x1gb pc4000 / 500mhz 184 pin memory modules
arrive

....will post result.

....thanks again,

regards, Richard

ps

....I did mention a while ago that bios is version 1.7

 

[RJK]

....have been trying to gradually increase bus speed from 200mhz upwards.
260 is a no booter !
250 is working, though strangely CPU-Z "Memory" tab says DRAM Frequency is
166.3mhz | FSBDRAM 3:2, and cpu speed is showing 1746.4/5 MHz
CPU-Z | CPU tab Bus Speed is reflecting the 250 set in bios - 249.5 MHz

lets' try a few more mhz ! ...oh how I wish my pc4000 would arrive !

regards, Richard

Well, HOORAH ...at last !
2 x 1gb "Kingston HyperX" KHX4000LLK22G arrived from ebay seller this
morning, so I removed
4x512mb Corsair CMX512-3200L, and fitted the 2 HyperX 184 pin (500mhz
LOLmodules, to Conroe865PE/e6300
( http://www.cpu-world.com/sspec/SL/SL9SA.html )
....and all seems lovely.
It booted up fine with 'Auto' | greyed out "266" showing in bios cpu
settings, and despite all I can throw at it, it seems stable and robust.
CPU-Z reports "DRAM Frequency 177.9" and "FSBDRAM 3:2" so a divider is being
implemented somehow ?, and is annoyingly not visible anywhere in bios P1.70

Memtest is trunnding along nicely atm - looks like it'll complete with no
errors, and it displays:-
"Settings: RAM : 177MHz (DDR354) / CAS 2.5-4-4-8 Dual Channel (128 bits)"

I don't pretend to understand why CPU-Z | CPU tab shows
Bus Speed 266.8 MHZ, Rated FSB 1067.3, and under the Memory tab -
"DRAM Frequency 177.9" ...something to do with that invisible divider I
guess !

Anyhow, my old Conroe865PE is up and running, now with a slightly higher
spec. cpu than the D935 that was in it, and old "Hot CPU Tester Pro (Lite
Edition) 4.4.1" benchmarks it (e6300 etc.) at "Total Score 8148 | MetaMark
to MHz ratio 4.36
last 2 benchmark runs give worsening figures - so rebooting ! ...av/malware
scanners etc. paused btw.

Main pc M3N78|x6000 2x1gb pc2-6400 / Hot Cpu 4.4.1 benchmark yields,
Total Score 11365, MetaMark to MHz ratio 3.79
(I think it was the "MetaMark to MHz ratio" that can be used to loosely
compare wildly differing PC hardware/software environments, though I may be
quite wrong !)

Anyhow, many thanks to Paul for very useful help.

regards, Richard

Sounds like it is doing what it is supposed to.

FSB1066 is for the quad pumped Intel front side bus. Dividing
by four, gives the CPU input clock frequency of 266Mhz. So 266MHz
is the correct value for the clock. You multiply 266MHz times
the "multiplier value" for the processor, to get the "core speed".
So, for example 266 * 7 = 1866MHz is a possible core speed, if
the multiplier was fixed at 7.

Using the 266MHz value, and multiplying by 2/3, gives the DRAM clock
rate. That is 177MHz, fed to some pins on the DIMM. That is
multiplied by two, to get the bus transfer rate. The RAM is,
after all, DDR, or double data rate, so you'd expect a factor
of two to be involved. If we take 177MHz * 2, we get DDR354. And
that is the value I predicted your motherboard would be using.
