and old A rig from the dust bins at goodwill.
NO OS stated, nor BIOS version stated at BIOS info page.
I'll assume there is no OS and just BIOS fails.
Leave bios in auto on DDR2. for sure.
getting good ram for old PC is not easy
you do know the old MMC (mem manager controllors)
stuck then right,> on density and type not just simple speed and fits slot. very complex that.
the sticks have ID chips that the BIOS uses to set them up
if the BIOS dont like your mem sticks it will never work.
The BIOS will run at the slowest speed of the slowed stick installed.
first ill attempt to read you PC full spec.
HP dont have it now , its gone to dead legacy mode. deleted the books.
looks like its 11 years old.
2006 made, oops not good
Athlon 64 X2 (W) 3800+ 2.0 GHz
The Atholon sets these rule(unlike pentium 4s)
if you read the data sheet on it its very restrictive.
it does support 4x1gb,
Kingston memory pages i bet fails to help you , i bet.
they dont make them now. so..... leaving only fleabay used mem.
not good that.
240 pin, DDR2 SDRAM
430 rules next , the HP pages are gone and the qualifed DDR pages with it... making , help on any Legacy box very hard.
but I do have facts on MMC
The BIOS rules ARE HPs and are now lost in the sands of time.
in most cases if you try each stick 1 by 1, on bank 0
if any stick fails in BIOS that stick is bad or not for the
Athlon 64 X2
The Athlon like all old processors even i3 and i5
have rules on max size per stick
max for all banks.
and chip density rules per stick
and even some can not run sticks with chips on both sides.
this is due to data bus capacitance rules too (limits)
why mess with this old air box.
why not get a modern 2 core mobo, say and I7 or
FX amd 2 core.
off hardware secrets page. (oxymoron)
Used by Athlon 64, Athlon 64 FX, Athlon 64 X2 and Sempron (some models) processors. On these models the embedded memory controller supports DDR2-533, DDR2-667 and DDR2-800 memories at dual channel configuration, meaning that the CPU accesses the memory at 128-bit rate if an even number of memory modules is used. Keep in mind that the memory controller found on socket 754, 939 and 940 CPUs supports only DDR memories.
you are running at
2.0 GHz 10x 5div = 800 MHz memory rate.
if we had the missing HP manual on memory
you would see a complex set of rules for population.
1 or 2 channel mode.
the Athlon chip maker and the mobo designer sets these rules.
try these,. they have a warranty
with 32bit os, the memory will show as 3GB (or tad more
