DFI Lanparty 875P-T LGA775 Benchmark Adventures

[eva2000]

I was lucky enough to grab a P4 3.4E 550 cpu on Christmas Eve to go with my 2nd hand DFI Lanparty 875P-T motherboard that I bought off Oppainter at xtremesystems.org forums Had a few initial problems in that the system didn't boot up but loosening the G4 Storm waterblock's mounting screws a bit on the DFI Lanparty 875P-T allowed it to boot.

System:

P4 3.4E 550

Overclocking:

I still haven't found my way around the bios options and not sure how well this memory performs on the 875P-T yet but I was able to boot and take this screenie at stock vcore - not stable

http://www.fileshosts.com/DFI/875P_...0-2226-15.6-FTM-CPC-SCPC-1.4-3.2-1.7/cpuz.jpg

Not bad temperature wise which was my main concern. I just have to test all my memory on this setup and see what works. I haven't installed my OCZ DDR Booster yet but I know it works with this motherboard so can pump more vdimm into my memory

So having a 875P chipset, does it also have the same affect in that 2x 512MB will result in more bandwidth than 2x 256MB memory modules ? I'll find out soon

Note: Seems the Winbond Hardware doctor's reported 12v rail is off off a bit, it shows 12.24-12.38v but from multimeter it says 11.98v idle and 11.94v load. So i'v raised it to 12.20v idle and see if that helps

Time for some overclocked benchmarks This 875P-T is very aggressive on memory and really puts out some nice memory bandwidth!

3.4E 550 SL7J8 @ 4097mhz at 1.5-1.53v vcore load
DFI Lanparty 875P-T 11/30 bios
2x 512MB OCZ PC3700EB Singles @ 241mhz 3-2-2-6 at 3.2v vdimm

dropping to 14x multiplier for some bandwidth benchies @ 251mhz 3-2-2-8 at 3.2v

Warning folks with this board, you have a high chance of frying your OCZ DDR Boosters if you use it with this board it seems. Fugger and another member on Xtremesystems.org forums between then have fried 3x Boosters.

I just tried my OCZ DDR Booster at 3.3v vdimm which is 0.1v above this board's max bios 3.2v vdimm. And I fried the exact same trace that Fugger did

The booster can still display what vdimm is set in bios, but can't be dialed higher than 3.2v.

Okay swapped out my MX480EL card and put in my Powercolor X800XT PE for some fun at stock cpu speed

P4 3.4E 550 SL7J8 @ stock
Powercolor X800XT PE stock cooling
2x512MB OCZ PC3700EB Singles @200mhz 2.5-2-2-6

X800XTPE @520/560

3Dmark2001 = 19,855
3Dmark2003 = 13,298
3Dmark05 = 5,982
Aquamark3 = 70,543
PCMark04 = 5,510

X800XT PE @575/599

3Dmark2001 = 24,268
3Dmark2003 = 14,177
3Dmark05 = 6,435
Aquamark3 = 73,192
PCMark04 = 5,500

 

[eva2000]

Anyway cracked 15k 3dmark2003

P4 3.4E 550 SL7J8 @ 17x247FSB = 4199mhz
Powercolor X800XT PE stock cooling @575/602
2x512MB OCZ PC3700EB Singles @247mhz 3-2-2-6

3Dmark2003 = 15,014

New Aquamark3 record @579/603 = 84,881

Well last benchie for tonight

P4 3.4E 550 SL7J8 @ 17x248FSB = 4216mhz
Powercolor X800XT PE stock cooling
2x512MB OCZ PC3700EB Singles @248mhz 3-2-2-6

3Dmark2003 = 15,035
Aquamark3 @579/603 = 85,165

Very nice score. Damn now I have to go push mine to see what I can sqeeze out of it. You have to be right at the 7k mark for 05 as well. Nothing to sneeze at thats for sure. Keep it up.

Will see if this new PSU does anything for me. I know you mentioned you got a little more OC with the shielded power cable, I hope that works for me as well.

Nice man, I have really considered this board as I'm seriously thinking about going back to Intel and I don't want to get rid of my X800XT PE, but want the Socket T CPU.

 

[eva2000]

thanks guys.. yup if you have a good AGP card and DDR1 ram already this board is just the right thing to get

Broke my previous PCMark04 high score of 6,360 with my 3.2EE@245fsb = 3920mhz.

P4 3.4E 550 SL7J8 @ 17x245FSB = 4165mhz
Powercolor X800XT PE stock cooling @575/602
2x512MB OCZ PC3700EB Singles @245mhz 3-2-2-6 at 3.2v

PCMark04 = 6,526

seems the clock generator on the board is a bit wacky

set FSB to
240 = 241 real
244 = 245 real
245 = 246 real
246 = 247 real
250 = 251 real

heh

My 875P-T arrived yesterday, and I just placed an order for a 540J CPU. Looking forward to getting it up and running.

 

[thelostrican]

is it me or this mobo has some issues with huge and i mean huge vcore drops and some issues with 5:4 div?

 

[mattspalace]

5:4 ratio!! Ewwww!!! I've heard nothing but good things about this motherboard which is why I bought one for my 540J.
