Hello All
This is my first post.
but i have a issue
i have a HP D530 SFF
its stock specs are
chipset I865G
P4 2.8ghz non HT 533mhz FSB northwood socket 478
512mb DDR533 (2x 256mb) dual channel mode
Geforce 6800 GT AGP 8x
WD 40gb ATA/100 HDD
i have migrated the hardware out from the SFF case and moved it into a Antec 300 case, bought a Antec Basic 500w (BP500U model) so i could use my 6800 GT on it. and all works well, had to slightly mod the Antecs front USB header connector to work on the HP mobo but it now works.
but here is where it all starts to go wrong. yes i know its a old system. i bought a P4 3.2ghz HT 800mhz FSB northwood CPU, and 2gb DDR400 (2x 1gb sticks) for dual channel mode.
i ran benchmarks on the stock setup so i could compare the difference once i installed the faster parts.
with the stock parts in sandra the memory bandwidth benchmark shows 3.5gb/s, and a latency of 140ms, i also used a software OC tool and used its benchmark, the ram tested the same, but also includes a L1 cache benchmark which showed 10.3gb/s read and 14gb/s write.
i put the new hardware in (3.2ghz HT 800mhz FSB, 2x 1gb DDR400) and ran the benchmarks, right off the bat i seen the system didn't boot as fast. i ran sandra and the memory bandwidth benchmark showed only 1.5gb/s , memory latency was 450ms +. i ran the OC programs benchmarks and the memory bandwidth test showed 1.5gb/s and showed the L1 cache read was 5gb/s and write was 6gb/s. i did the same with HT disabled and got about the same results. i even tried single sticks which resulted in almost identical scores as below.
i double checked in bios that the CPU was operating at 3.2ghz 800mhz FSB, and the ram was being seen as DDR400 in dual channel, also checked sandra and showed me hte same and also showed a low memory bandwidth warning saying the timings are set wrong or the memory was in safe mode.
figuring that it might be the Ram cause the low numbers and slower performance i put the DDR533 in it and gave it another run (knowing that the DDR533 will get under-clocked when paired with a 800mhz FSB CPU). but i ran all of the benchmarks and the memory bandwidth test showed 1.06gb/s and a latency of 500ms, and the same on the OC program and showing the L1 cache even slower at 4gb/s read and 5.3gb/s write.
so i removed the stock ram and put the new ram back in, and removed the 3.2ghz CPU and put the stock CPU back in. ran everything again it got the same benchmarks as the first time i ran it and was back to the same level of performance.
the mobo is suppose to support 400, 533, and 800 mhz FSB, DDR2100, DDR2700, DDR 3200 in single or dual channel mode.
i am not sure what happened. but i didn't expect to have a big performance loss like it did. can someone help shed some light i this. could the CPU be going bad or could the mobo not like running at 800mhz or needs better ram or what.
Thanks
Frank
