DFI Lanparty 875P-T LGA775 Benchmark Adventures

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

SL7J8

Malaysia

 

DFI Lanparty 875P-T with 11/30 bios

2x 256MB KHX3200K2/512 BH-5

64MB Albatron MX480EL (for testing)

120GB WD 1200JB

Pioneer AO5 DVD Burner

580W Topower 686P6 Adjustable rail PSU

 

CPU cooled by:

 

Cathar's G4 Storm waterblock with revised stepped base addition for LGA775 cpus

Swiftec MCP650 Pump

Thermochill 120.3 with 3x 120x38mm Panaflo 103cfm fans on 3.5" Rheobus 13W per channel

Dangerden fill port

Clearflex 1/2" ID tubing

 

Stock benchmarks:

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

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 :D

 

Edit:

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

you shouldnt need a booster since the board will give 3.2v but then i suppose it depends on what memory you are using (since its not listed in your sig)

 

the overclocking should be good for default vcore up to 250FSB (about 700-ish Mhz overclock for me before I had to start raising vcore).

 

i've an xp90 on mine but now i have all this great DangerDen stuff so i will be heading back into the 875P-T one day soon...

Yeah i have piles of memory to test on 875P-T including OCZ Gold VX and several varieties of BH-5/6 ram which excel at 3.3-3.6v vdimm :D

 

Currently testing the lower vdimm capable stuff first i.e. 1GB OCZ PC3700 Gold rev3, then 1GB Centon PC3200 Advance Samsung TCCD, then see how 2x1GB OCZ PC3200 Performance DC kit does :)

that Centon would net me 260FSB @ 3-3-3-8 I think (cant remember since i tried a zillion DIMMs in it too).

 

the OCZ stuff should really excel without having to go extreme voltages, but with 3.2v my BH-5 will do very nicely (never did test it on the 875P-T, just going off my LPB/UI).

i can't get my 2x 512MB Centon past 248mhz 2.5-3-3-8 @ 14x multiplier heh

 

but so far i'm at 4097mhz priming

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

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 :)

Well I truly went and broke my personal best score of 14,813 with my new 3.4E 550 SL7J8 and same Powercolor X800XT PE stock heatsink and with room to move too (no place to put the zalman fan bracket so no extra 190cfm delta air cooling over card yet).

 

But @ 575/602 still managed 3dmark2003 score of = 15,014

 

P4 3.4E 550 SL7J8 @ 17x247FSB = 4199mhz
