It's up, it's running and it's friggin HOT!

Another D2OL cruncher up

Finally had the time to put the 3.06 Xeons in a board ( PC-DL, rev 1.05 ). It is producing candidates, been running for 8 or 10 hours.

I had to detune the chip to 2.66 til I get my shipment of Arctic Silver Adhesive and some other goodies, here.

Not sure if I needed to ( and may undo it, depending on results of improved VRM and MOSFET cooling ), but I did the 1.525V to 1.60V UWire and insulated pin VMod. This friggin system is just way hot right now.

Will be improving over time as I learn to tweak it ( and better cool it ).

My understanding is that with a multi of 23, it will always initially, for a split second, try ( and fail ) to boot at that if I was to drop the multi and raise the FSB?

So, ClockGen is my friend? Any thoughts or ideas?

How hot is it running?? I dont think the u-wire mod is necessary. As for the clockgen/multi thing, I am not sure what u mean.

Well, with the 2.0 Xeons that have a multi of 20, the machine will always attempt, briefly, to boot at 20 x nnn. So, even if you've lowered the multi in the BIOS ( and raised the FSB to say 200 ), the board will still try to boot at 20x. And fail, cause 4000 mHz ain't gonna happen.

Was wondering if the 23x multi of the 3.06 works with the PC-DL like that. If so, then, I can set the multi to 15 or so, leave the FSB at 133, let the chip/board go ahead and boot at 23x ( cause 133 x 23 will work, as it is the default ), and then have it actually boot all the way into Windows with the 15X multi. At which point I'd use ClockGen to increase FSB.

Can anybody confirm this is how it works, or is my understanding flawed?

I'm not sure how these chips with the higher multis work. That is why I was inquiring. Inquiring minds need to know! :)

Heat...

Right now, at 2.66 >> 61 VRM , 53-54 CPUs. At 3.06 >> 70-72 VRM

Put a delta on em :D

yep thats right

Yes clockgen is your friend indeed. :)

I think you are better off going back to stock Vcore and eliminate the heat problem. Just my two cents. Mine crunch in the low 40Cs(CPU) with that setting.

DDTUNG :cool:

Now we want to se some oc :) maybe time to put them under water?

[{PMS}fishy]

Maybe I missed it, but what HSFs are you using? The stock IWT aren't going to cut it for these CPUs with 1.6v. Maybe some of the copper Nocona ones, or better yet a pair of Swiftys or some water cooling.

I'm thinking these chips were was near the tale end of that "run", the "130" process. Guessing they just run hot, naturally. Then, I threw up to an extra .075V's on 'em.

I'm waiting to get my AS Adhesive to redo the VRM and put some sinks on some of the MOSFETs.I put brand new Sunons 39 CFM thinking they would do. Usually I use 50 CFM Sunons on HSs. I'm thinking I need to swap some stuff around; gonna put 80mm Tornados on 'em. And hopefully the mid Sunons will be alright on the AMD systems that the Tornados are on. I'm also thinking I need to order me some more 50 CFM Sunons.

Yes, olfen, I want to OC. I've never done water. Kinda figured with 20 plus machines, where do I start? Or end! :D

Start with the first one, and end with the last one.

Those sinks should be plenty for those chips even at 1.6v. I didn't start to notice any stability issues untill over 50c and then things started to get screwy. Also with power hungry chips like those, you deffinatly need to mod the VRM sink and probally add something to the rear VRMs as well. With my 1.6s @ 3.3 1.65v I was getting 65c+ on the VRMs.

Which rear VRM's? Can you post a picture and circle which IC's you sink. I know about the one between the NB and the AGP slot, that Jeff talks about and illustrated in his guide. But you are talking about something else. What rear VRM's? Can you post and mark up a picture so I can see?

Will have my adhesive Monday or Tuesday.

Also, I have some small sinks, certainly enough to do this job. But would like to do some more ICs on other systems. Where do you guys get your mini-sinks? Always good to have other sources, other resellers and vendors. feel free to chime in with suggestions, brands and URLs, please.

They are on the back of the PCB, right behind the VRMs on the front. Hard to miss, its the only thing back there.

I just cut up old heatsinks. I don't see the point in spending money on sinks when I have something that I can make work.

It is only with these Xeons that I've started to use Swiftechs. I'm not real fond of mounting them. Frigging pain in the keister!

These Xeons are my first Intel systems since my old BP-6. I use Thermalright sinks on my AMD systems ( should have bought stock! ). Have a veritable army of SLK-800, 900, 947, 948, XP90 and Xp90C's. And one or two AX-7's and xx-6's no longer in use or around.

Kinda wish Thermalright would make a series of sinks for Xeons. Yeah, I know it is a niche market, but Swiftech does alright, I'm sure, with theirs.

Think I'll send Thermalright a link to this thread...

...bastages, where are they when you need 'em! j/k :)

Ahh, gotcha. I'm thinking whatever you would put on those would have to be pretty short, not much clearance back there.

Or you can cut a hole in the back of the case. That seemed to work best for me.
