Building a dual 1.6GHz LV Xeon cruncher.

I just got my PC-DL today, are there any other mods suggested to run over 200fsb aside from the ones listed in Jeff's article?

there was a guy over at 2cpu.com who was working on a vdd mod but i dono if he worked it out yet, i cant remember now but there may be another vcore mod described over there.....its worth checking out

http://forums.2cpu.com/showthread.ph...highlight=pcdl

the thread is 329 pages long lol....might wanna grab a coffee first

[FDM]

thanks, book marked it, I will attempt to read at least part of it when I finish writing the couple of papers I need to finish.

Also, anyone who watercools dual cpu rigs: do you run the blocks in parallel or series?

[chipmonk010]

yeah im curious about that myself^ ive seen it in series but i would think paralell would be better, wouldnt it?

5. Connecting the water-block(s) to the cooling circuit: Carefully identify the direction of the flow in your circuit. For the MCW6000 to operate properly, the fitting located at the center of the water-block MUST BE USED AS THE INLET. In multi-processor environments, connect the two blocks in series: For example: pump discharge to inlet of processor 1, discharge of processor 1 to inlet of processor 2, and discharge of processor 2 to radiator.

thanks rod, interesting they say to do it series....

[Rodzilla]

I would have guessed parallel... but I'm not all knowing...

[matt9669]

It has to do with how powerful your pump is - if it can sustain good flow rates when used in parallel, the temp of the second processor will be lower. However, if the pump can't push enough volume, you're better off overall in series.

Water flow is fairly analogous to electrical connections: when connected in parallel, the flow rate is ~1/2 of that in series. Of course, there's less flow resistance through one block in parallel than two in series . . .

If you know you have a pump that performs above average and don't have a massive rad/long tubing lengths, I'd say parallel. If the water has to go longer distances and has a long trip through the rad, serial would probably bring lower overall temps.

w00t!! Just ordered 2 Swiftech MCX603-V's. The mobo is sitting here. Now I'm just waiting on the fricking CPU's and the PSU ( entered one of the #'s wrong, but fixed that today ).

I'm anxious to get this moving forward!

And owning all those people in the world. XS is moving higher and higher.

Hi Jeff,

Question, If we apply the new bios hack by FinalZero http://www.datamine.tk/ to the PC-DL board, all of these mods will no longer be necessary, right? That is, we'll be able to set the vCore, vDDR through the bios? That's what they claim at least...

Have you had the chance to try it? What do you think about the hack anyway? I'm trying to build a video-editing machine. Very new to all this mod'ing and bios changing. I don't mind going in and doing the changes you suggest, or I suppose the bios update to the FZ one. Only thing with the bios update is I'm a bit afraid that it will screw the board up somehow since it's probably not throughly tested. And then leave me completely lost!

Thanks,

WARNING: These are all very very very experimental, some barely work, others not at all. It is recommened that you have some form of backup BIOS chip for recovery (or a 'RD1 Bios Savior').

id say its probably not a good idea... form the looks of that

The BIOS is from a NCCH-DL mobo... I would be careful...

Site doesn’t seem too be all that impressive enough to attract reliable modders...

[Jeff]

Vddr is NOT adjustable through that BIOS and will never be through any BIOS. The board's hardware isn't capable of it so it's impossible. I mentioned that earlier in one of their threads and P4N came back a while later confirmed it wasn't changing.

Vcore... don't really know if the BIOS changes that... I have a feeling it doesn't to be honest. If the hardware could support that then I think Asus would have included it somewhere along the way.

I honestly haven't been keeping up with what they are doing with the PC-DL BIOS over at 2cpu.com. It's a neat attempt... but I wouldn't buy a PC-DL just because of it.

I'm really interested in getting one of these beasts. The PC-DL has no problem running stabily at 200FSB? I noticed some of your rigs were reset a few hours ago, was that a stability issue? Expect 1-2 of these from me in the next month or so

[shadowing]

Who wouldn't? I'm interested in it. But too bad, I'll go Opteron. Those two chipset solutions are .

16 SATA II!!!!

Yeah, stability of my hand to NOT turn off their power strip.

No stability problems here except when I try getting a few more GHz than I know is stable. I keep hoping for "burn-in" to help the chips go farther.

Will those be crunching for the D2OL team????

preface to make me unwanted in here

i haven't (ever) been in one of the folding forums i think and might not happen in here again, but this dual xeon thread caught my eye and immediately an idea pops up in my mind.
i'm admin at my workplace and besides that i am doing a good deal of graphics and lately some 3d-modelling and animating there now - which will probably be increasing over time percentagewise... doing this on a p3 933 - and a sketchy 640x480 testrender (not even tuning all the bling bling up to high or better) takes ~10mins to render. so has anyone in here ever done 3d-work with a monster like this? i'm asking because these 2x3.0 ghz just sound too tempting to get - and at $110 (which is even less in euro, about the price of a new xpm2600) it is a steal. so if these things are as powerful as they seem to be, i might build one such "render-slave" for the office - and maybe add one for my personal collection along the way
i found some numbers via a google search, but those were a pair of 3.06 ghz, 1mb, fsb 133 (???) xeons. how would these 1.6'ers at 3.0 ghz with 200mhz fsb and only 512k do? does anyone have a bench or numbers to show regarding this? if so please post (pm me?)

btw if this post is considered offtopic - as it has nothing to do with folding and would probably be more suited in the general intel forum, just tell me and i'll remove it.

I think its safe to assume that there will be a couple of xeon crunchers showing up as new d2ol nodes soon enough :banana4:

This is the 3rd or 1000000th time I have heard a cry for benchmarks...

I want to see some too!!!

Sky... your post was fine! Everyone is welcome here! One of the biggest things I liked about this thread is that I knew it would get a lot of attention! Nothing like this to get some new faces in here... maybe even get them to fire up a client or 2... or 30!

[STEvil]

on a side note, how well do P3 933's do at this? I picked up a pair of them (slot 1 chips) and need to find a motherboard for 'em now.

They should do alot better than your current P3. They should do very good. If your using it for work though they mite not let you mod the motherboard, but you can check. I think this is definetly an area where opterons are not what you are looking for.

[sky]

hey, i'm admin ... there's no one to stop me ...
and well i'd expect a dual 3ghz rig to beat my p3 933 in anything (maybe except bootup times, lol). but where would it be compared to a current (give or take a few months) technology single-cpu system, like maybe p4 3.2g, a64 3200, axp @2.6ghz. on some of the cg- & renderforums i frequent, people are using dual xeons, but they can't tell how much more (or less) performance this solution offers to anything else - after all they only have one system. so i'd think people around here, who are likely to have more than one current tech system know a bit about that.
oh and i'm totally neglecting the difference in pricing between current tech and dual xeon, because if that is taken into account, the duallie probably beats most anything - besides an amd xpm processor-based system.

btw thanks to you rodzilla and all the others for bearing with me here

Well,I've read yer posts and I got a couple 1.6's I'm gonna try on a PD-DL MB. Will be interesting to see how high it'll go.

So, Plum, want to join us with a few machines? Its a good program!
