Corsair 5400UL & Asus P5WD2 DDR860 4-2-2-2

[The Stilt]

I got my Asus P5WD2 Premium board yesterday from one of our distributors. They had received their shipment from Asus just few hours earlier, so this is probably one of the firsts Glenwood boards seen in Finland.

Because my Corsair 5400UL sticks couldn´t meet their limits on any 925XE board, I was quite eager to find out how would they perform on 955X boards.

So I ripped the package open, and bolted my 660 chip and 5400UL sticks on.
I dropped the multiplier to 14x and yanked and yanked the fsb up with SetFSB program...

First time system failed at 14x308 clocks, when memory was operating at DDR820 speed. I was running them at 2.3V, which was the highest voltage that can be selected from the bios.

Naturally I wasn´t satisfied, so I made a DDR VDD mod for the board. Then I raised the voltage to 2.39V and booted up for the second run.

Now I was able to hit 322FSB. 322FSB with 3:4 memorydivider means 430FSB or DDR860 for the ram so here we go


Corsair 5400UL @ DDR860 4-2-2-2 (Verified)

P4 660 @ 4520MHz (1.35V, stock cooling)
Asus P5WD2 Premium (VDDR mod, active cooling on NB)
Corsair 5400UL 1GB Kit (4-2-2-2-5-Turbo-HyperPath3 enabled / 2.39V)
Matrox Millenium II PCI

Thanks for Franck Delattre for CPU-Z version with P5WD2 support, and abo for SetFSB program.

I´m currently held back by cpu, since 4.5GHz is pretty much maximum with stock cooling
I´m going to bolt on my Mach2 and see how these sticks really perform.

Get to the good stuff, and show us what them sticks can really do

[Twisted-net]

I want to see some sandra membench of that

[b|gf|sh]

Dude thats amazing like

Would love to see some Everest bandwidth screenies at those speeds

[Supertim0r]

beat this monster

[The Stilt]

Get to the good stuff, and show us what them sticks can really do

I will when someone sends me the bios that was used in the sample boards. It would allow use of 2:3 (1.5x) and 1:2 (2.0x) memory dividers

WoW

[LarsK]

Awesome stuff, just what I what to read about

Man now I really can't wait to get the P5WD2, I've got one waiting at the post-office but can't get it before tuesday because monday is a national holiday....

What rev. are your Corsair memory sticks? I've got at dual kit with the same rev. number as the ones Anandtech tested, ie. "XMS5400v1.2 0515017-2". Haven't tested them at all yet, just got them from Germany last week. Had to get the mainboard from Sweden as well....

Arrgh now I really can't wait to give the system a go in the Mach II GT...

Is the Vmod fairly easy on this board, and how much extra voltage can you potentially get from a Vmod, and what voltage is still "reasonably" safe for the memory? Hope you don't mind the questions, but that's what you get for running cutting edge hardware...

Here are some results:



Corsair 5400UL @ DDR900 4-2-2-2 - SuperPI 1M (Verified)

Corsair 5400UL @ DDR906 4-2-2-2 - Everest Write (Verified)

Corsair 5400UL @ DDR906 4-2-2-2 - Everest Read (Verified)

Corsair 5400UL @ DDR906 4-2-2-2 - Everest Latency (Verified)

Corsair 5400UL @ DDR906 4-2-2-2 - Sandra 2005 Buffered (Verified)

Corsair 5400UL @ DDR906 4-2-2-2 - Sandra 2005 Unbuffered (Verified)

With correct operating system, I would have hit 5000 in Sandra unbuffered with same clocks Unfortunately there isn´t SetFSB or Clockgen program that works in this OS.

P4 660 @ 4760MHz (1.43V)
Asus P5WD2 Premium (VDDR mod, active cooling on NB)
Corsair 5400UL 1GB Kit (2.49V / 4-2-2-2-5-Turbo-HyperPath3 on)
Matrox Millenium II PCI
Mach2 R404

These sticks seem to love voltage, so for next run I will bump it up to 2.55+

LOT code of my sticks are 017-5 v1.2.

VDDR mod for this board couldn´t be any easier. Simply solder 10k vr between sixth leg of RT9214 chip and ground. 8k resistance will give you stock voltage, and 2.49V will be achieved with 4.4k resistance when 2.3V is selected from the bios.

I assume that ~2.6V is the maximum voltage that should be used with these Micron BT-37E "Texas" chips. Japanese guys have used 2.8V with Samsung CD5 chips for benching.

[Bennah]

This is overclocking at its best

Get the board only a short time after Asus start to send them out. Try it out on air. Needs more vdimm so you figure out a vdimm mod. Still not happy so the Mach II gets dusted off and bolted on, then the fun begins. Produce a bunch of benchmarks and verified screenies

Great work The Stilt, Im impressed with his Intel stuff

[saaya]

very nice man! congrats

front page worthy!

[Supertim0r]

Do they get hot ?
How is DDR2 compared to DDR in term of heat ?

[5-Clicks]

with lower volts = cooler generally...

nice results Stilt!

Excellent, thank you very much Oh, and congrats on the results as well, simply awesome

[elec999]

You have an amazing system.
Very nice job with the ram
Thanks

[Xassius]

ddr2 = ultra cool compared to ddr.

[robberbaron]

Just imagine what kind of latency that would be getting on an AMD system! DDR2 is pretty nice.

[Astral7]

Very nice The Stilt! Looks like DDR2 has finally arrived. Those timings at those speeds are amazing.

[IluvIntel]

I got the same sticks as The stilt, but are limited by the 925X chipset and P5AD2 - MoBo.
I'm curious as to how they handle sustained bandwidth transfers at those 900 + speeds and with those timings, I mean its one thing to boot into windows and run Everest and Sandra. But can they handle the "Acid" test, eg: running 2 x distributed computing projects and net surfing and emailing at the same time with 100% cpu load without crashing or lockups? This is doing it for several hours or more.

But its really good to see someone doing great stuff anyway with this combo of MoBo and Corsair.

[FX Freak]

nice overclock, ddr2 forever

[blackjok3r]

Give us SuperPi 32m please. Stability will be proven then.

[kromosto]

unbuff scores are like buff scores of a 478 on 865 or 875 without pat

I know hey? that's flippin' sick.....congrats Stilt, truely amazing.

DDR960 4-2-2-2 is history

1GHz speed wouldn´t have been a problem, if I could get over 1.52V vcore out from the board...

Anyways here we go again:

Corsair 5400UL @ DDR960 4-2-2-2 - Everest Read (Verified)

Corsair 5400UL @ DDR960 4-2-2-2 - Everest Write (Verified)

Corsair 5400UL @ DDR960 - Sandra 2005 Buffered (Verified)

Corsair 5400UL @ DDR960 4-2-2-2 - Sandra 2005 Unbuffered (Verified)

System:

P4 660 @ 5.05GHz (14x360) 1.52V
Asus P5WD2 Premium (VDDR & Vnorth modded = 1.88V)
Corsair 5400UL 1GB Kit (2.65V VDD, 4-2-2-5-Turbo-HyperPath3 enabled)
Matrox Millenium II PCI
R404 Mach2 for cpu and Swifty MCX-159R for chipset.

Without Vnorth mod and Swifty on chipset the board was pretty much maxed out at 340FSB with 3:4 memory divider. After raising Vnorth voltage from 1.65V -> 1.88V and adding Swifty MCX-159R I was able to reach 360FSB.
Without vnorth mod and better chipset cooling I was limited to 343FSB no matter how much voltage I fed to those sticks.

With 2.65V VDD these sticks don´t even warm up that much, and they still seem to get advantage from higher voltage. Currently I´m limited by cpu, because I can´t get any higher vcore than 1.52V out from the board. If the bios wont solve the problem, atleast vcore mod does. With Abit AA8XE Fatal1ty this chip maxes out at 5.4GHz with same cooling

1GHz DDR with 4-2-2-2 settings is pretty close now

[jVIDIA]

It's so nice to see such a worderfull setup like yours, doing so good

I'm also waiting for a P5WD2 Premium and 1GB Corsair XMS2-5400UL

But I'm on air and still dont know wich cpu to buy : 630 or 640 ?! Any advice ?

I will when someone sends me the bios that was used in the sample boards. It would allow use of 2:3 (1.5x) and 1:2 (2.0x) memory dividers

The 2:3 and 1:2 divider don't come in the retail bioses ?

What do you think of the new OCZ EB PC2-6400 and the OCZ EL PC2-8000 !?? What's the use of the 8000's ?


edit:

In the Anandtech review of the Asus P5WD2 the used the Corsair 5400UL and the say :

We were amazed to find that the Corsair CM2X512A-5400UL could reach DDR2-1066. This yielded a Sandra standard bandwidth of just over 6400 MB/sec. To put this in perspective, this is the first motherboard and memory that we have ever tested capable of running at DDR2-1066. Frankly, 1066 required slower 5-5-5-15 timings at the maximum 2.3V available on the Asus. We also needed to push all chipset and bus voltages to the maximum and set CPU voltage at 1.60V to achieve this milestone.

Could it be the mem's were not common retail ones and where choosed ?
