975X + E8400 = Works Fine, Fast Board Too.

[Kunaak]

Tonight I had about 3 hours to play with a Asus P5WDH that my friend has had laying around for a few months now.
I wonderd if it could run a 45 nm chip, as I was looking over Asus site today, and saw they had new bioses that hinted they might work.

heres a few results.

Hardware Used.

Asus P5WDH 975X - Bios 2504.
2 x 2 Gb Mushkin PC8500, and Corsair 2 x 1 Gb PC8888.
E8400.
Fresh Install of Windows XP - No Tweaks.

Board is completly unmodded, even my hints that the board severly needed it didnt help sway my friend into letting me do it, haha.

the results here are from 9 x 440, which the board handles just fine.
results are from both cas 3 and cas 5 tests.

Heres a Interesting one.

3960 mhz with cas 5-4-4 is slower the cas 3-3-3 and 3830 mhz.
weiiiiiiird.... I knew these old 975's are real sensitive to latency but this definatly had me grinning.

[Kunaak]

Heres some Max OC stuff.

I know its nothing amazing, but given the history of this board, I wouldnt say this is bad at all. I know these boards arent known for hitting the best FSB's. but the latency of the board is definatly fast.
I mean, check out the 40.3 results in the Everest Shot, thats definatly a hint at how fast this chipset can be.

4096 mhz.

My Thoughts.

Asus certainly made good on making this older stuff work well.
the 975 chipset reminded me just how fast it really was.
its definatly got limited OC potential, anything above 450 is very hard to maintain stable.
but if you have 1 of these laying around, a E8400 certainly isnt a bad choice for 1, given how easily they hit near 4 ghz at very low voltages.
sometimes just having a decent speed at low voltages is good enough.

I had fun playing with this board, I just wish I had longer to mess with it.

That's a pretty good OC for the 975. At least your temps look normal. Mine is 47C idle which totally doesn't make sense.

[rbsmontemor]

You need to do this test with Bad Axe 2. Mine did 475FSB on strap 266 for benchmark and 463 for normal use. No mods at all.

BTW, nice results...good old 975X

Rbs.

Nice seeing my board hasn't been totally written off yet

To bad fsb with quad is ty

[dinos22]

the SuperPi PP is not all that great Kunaak
~46.6K

[aoch88]

Super PI is just numbers. Anyway, we can't expect much from a 975, do we?

[Leopard*SEAL]

Preparing to build a PC around an E8500. I know where I can grab an ASUS Commando ROG board for nothing (box in buddies garage! ) Do you think I could get similar performance out of a 965 board with the new 45nm BIOS revision?

[Marvin_The_Martian]

Doesn't p965 always do better fsb then i975, it does afaik? And check Eva's thread about commando + 45nm wolfdale think that answers your question

Thanks!

i was never able to go higher than 425 FSB with my P5W. good work on yours, Kunaak. my P5W will finally get retired this week when my Bone Trail arrives.

[Eastcoasthandle]

A lot of people still use the P5W DH Deluxe and IMO the most popular board I've seen to date. Many come close to it's popularity though. This needs to be added into the P5W DH thread IMO, good work!

[BTK]

seems like these wolfdales are working good with the older chipsets too

p965 did over 600fsb
975 good but not great

particularly asus

It does not surprise me that 1333Mhz FSB chips can "unoffically" work with a 975X. Intel has not change the VRM specs for new chips since Conroe's introduction. The catch with 975X is that you have overclock the FSB to 333Mhz in order to run the 1333Mhz chips at full speed.

It all reminds me of how some users got P3 Coppermines to work on 440BX boards using a Socket 370/Slot I adapter and overclocking FSB to 133Mhz.

I think it is safe to say that 975X is modern incranation of 440BX.
