eshbach and Evil_Spork suck at Overclocking a Diego

[eshbach]

For about 3 hours we couldn't get the system to boot. Then it turned out that i had screwed up the mod on my 6600, so we put an X850XT in and it started working.

but for another few hours we couldn't get past 2.6ghz on my water cooling. nothing we tried seemed to work, and temperatures were very good (always below 30C).

finally we tried the diego in spork's board with stock winchester heatsink and stock voltage, and it easily did 2.8ghz. then we put on the water cooling and sure enough, 3ghz fell easily. max screenshot was a little over 3100mhz at 40C on water.

tomorrow this chip is going under dry ice, but here are some screens of tonight's action.

Wow, seems very weird. Were you both on DFI nF4?

[eshbach]

Wow, seems very weird. Were you both on DFI nF4?

yep, both DFI NF4 Ultra-D's.

we even hotflashed the bios on mine, got it a little better but not much.

[Evil_Spork]

eshbachs mobo just wouldnt clock anything.

even my winchester in his board under water with high volts wouldnt do what i can do on stock air. with 1.55v and water on his board it wouldnt do 2.5. i can do 2.6 on stock air.

the diego wouldnt do 2600 on water either... with high vcore even. with my mobo it went right to 2.8 on stock voltage seemingly with ease.

well investigate it tomorow more.

[MaxxxRacer]

nice clocks there guys.. i got to get me a san diego...

[(sin)morpheus]

Yeah, good stuff. Clock it high and get me interested in getting a sandiego again! :D

[afireinside]

So is this what was poping around on my AIM this morning spork? Nice :D

[SIOUX]

damn...that sounds very weird about your mobo:( But cant wait to see some results:)

[perry_78]

Yeah, the mobo part seems rather screwed. Now I know whats holding me back :D

Nah, its still fine. Nice results on SD. What gains are there at max bench speeds compared to 2610mhz Winchester?

well find out tonight. gunna try for somethin like 34k with my x850 stock.

well try both chips at the same settings to see as well.

[STEvil]

check board capacitors :P

[eshbach]

well find out tonight. gunna try for somethin like 34k with my x850 stock.

i think we'll be going for something like 43k with the diego at ~3400 and ice water on your X850 ;)

[Nanobot]

Well done !

Could the lower OC on Eshbash's board be caused by the power supply ?

I find it very interesting that this SD has good results above 1.6v since most of the new Venice & SD cores dont seem to respond to voltage above that level.Another bug maybe?

[Bennah]

Nice clocks there guys :toast:

Always good to see teamwork :D

Good luck with the Dry Ice tomorrow. Trying to beat Charlie's 3306MHz 4000+ SD w/ DI :D ?

same powersupply used each time, my OCZ 520w.

tonight we will be trying with spork's OCZ 600w.

and yes, we hope to get a bit higher than charlie... a 70C swing in temperatures should net us more than 200mhz I would think. we'll see.

[skate2snow]

Its probably the board power supplies.... Not the PSU....

What most doesnt really understand is that the motherboard IS THE MOTHER, some overclocks better then others.... With most of the boards I got, I got 3, all overclocked differently....

[fatfreepork]

how'd you get 2-2-2-2 ram timings?

[eva2000]

nice i should have OPB's 4000+ sandy by next week coming to OZ :D

[skate2snow]

how'd you get 2-2-2-2 ram timings? Depends on the RAM's man;).... TCCD and BH5 can do that...

[eshbach]

just got back from benching with spork.

he has all the pictures and stuff so i have to wait for him to upload those, but just a brief overview of the diego on dry ice:

3300mhz stable, super pi runs done.

we got through all but one test of 3dmark01 we started having problems. we may have two dead motherboards at this point. we have one thoroughly corrupted bios for sure.

volts beyond 1.7 don't help at all, but it could easily have been our cooling since our temps were climbing into the positives with about 1.77v

i'll have a cascade from PC ICE tuned for San Diego temps in about 2 weeks and 3500+ should be benchable at that time.

well also have 2 more single stage units for...... gpu?

ill post pics ASAP, screenshots and the like will have to wait a bit.. the bench bench is a total disaster zone after 5 mobo switches and as many cpu swaps. but for now its nearly 5am, so im gunna catch a few Z's. hopfully ill have time to post a few pics tomorow morning. ill at least try to upload them. :)

something went wrong... not too sure what but i think its this blasted DI tube. we need phase change. :slap:

superpi got weird and messed up. strange huh?

http://www.evilspork.net/es/comppics/diego/small/IMG_2612.jpg
another shot, and you can see our superpi times at 3300mhz. we later got down to the mid to low 25s range.

http://www.evilspork.net/es/comppics/diego/small/IMG_2616.jpg
this is where it started going downhill... condensation, small puddles!

http://www.evilspork.net/es/comppics/diego/small/IMG_2625.jpg
so we moved to eshbachs board. he insulated it this time :rolleyes: :p:

http://www.evilspork.net/es/comppics/diego/small/IMG_2627.jpg
the back

after this point we didnt really have any success to speak of and we spent most of our time trying to get the stuff to work. condensation got both out boards shorted and unwilling to boot. the sandiego might be dead, or we might have hosed all 3 bios chips.

the results and such will have to wait for a bit. i need to get my setup back up and running or the hdd on another system to extract the screenshots and cpu-z validations. :(

[esdee]

come on you guys ... use some more insulation!!!
i use 3 times more unsulation than this on both sides of the CPU

heh... well once we get phasechange setup we definatly will use better insulation. this tube makes it very hard to insulate due to the shape, size, and mouting.

we should have 3 phase change units within 2 weeks. 2 single stage and a cascade. at that point we'll have my x850 under phase change, and the san diego on the cascade. (and the third single stage to cool our drinks :D)

i think a 70 degree temp shift down should help the diego. our top clocks were between -5 and +5*c, the cascade form PC_ICE will be tuneable and ready to hold loads at about -70. were hoping the diego will work at -70.

the pic was from my dry ice run, but i used the same insulation on the phase too.no condesation after 10 (!) hours of dry ice.

good luck with the sandy under the cascade!

thanks!

if this tube had a differant mount and a smaller base we could have insulated it to last virtually forever. just how its shaped theres air gaps we cant fully cover without compromising contact and such.with the phase were using a totally differant mount that will be about 2 inches off the mobo and allow for massive insulation with basically a hole cut for the evap and the screws.

in other words, when we get the phase units we should have this down to a science and put out some fantastic scores.

i think we have enough for about 37k with stock x850. eshbach says 40k will fall. i hope he's right!

we were getting around 100fps better(in each test) than my 31.2k score on the winchester. we might have my single stage expirimental unit ready by sunday(if everything goes well and we get the parts)

cliff notes for post:
1. our insulation wasnt very good
2. this tube is too hard to insulate
3. once we get phasechange(2 week-ish) we'll insulate better and make a run for front page 01.
4. profit?

[perry_78]

Nice setup :D

Still what bugs me more than anything else is eshbach's board's inability to overclock anything at all :(

[Evil_Spork]

were thinking its the bios. or possibly the actual bios chip itself. with his bios in my board it wouldnt boot at 3300mhz anymore. after that everything got totally borked. :slap:

SOOOOOOOOOOOOOOOOO, maybe his bios chip is bad? or that bios doesnt like our setup? who knows!

give us 2 weeks and well be back with 40k in the bag. ;)(and hopfully a WR or two)

[esdee]

waiting to see your results then ;) good luck!

[Jort]

yeah insulation is a big problem, yesterday we spent 30 min on insulate our mobo.

because we used a container with a big base, insulating the dfi is hard.
http://users.telenet.be/jortcollijn/project%20dry%20ice/base_polisched.JPG

capasitors gets wet :p: and the mobo itself just conducts the cold.

3 layers of insulation isn't enough to keep the cold

oke it was with ln² but still, after a wile the mobo wasn't booting so 30min in oven and it was back oke.

hope you get that cpu and mobo work out and put some good score's here:)

[eva2000]

what about stuff like pcb lacquer spay + liquid electrical tape application before using neoprene for insulation ???

its all lathered with dielectric grease. ;)

[mrlobber]

Wow, some impressive plans described here :D Hopefully, equally glorious benches will follow :up:

[JDizzle]

What do you think it actually was that was causing you guys to not get a good overclock at first? I'm sort of having trouble with my Venice also. I cannot get it to even boot into Windows at anything above 2.6GHZ and it's no where stable at around those speeds. My motherboard isn't in a case and is just sitting on an anti-static bag, could that be it?

no, all of our runs were done like that. try different bios.

With my first A64 setup I have a really strange problem...
I was waiting for a new case to mount up all the hardware, and I mounted it on the table until the case arrived...
I mounted the mobo laying on an anti-static bag, and it didnt boot up. If I remove the antistatic bag and put the mobo over its box it booted perfectly, so trying removing the bag...
Its weird, but I have suffered it... :confused: :confused: :stick:

P.D.
The mobo was an Abit KV8 Pro with a 3200+ NC, now I have had my DFI NF4 on a bag too, and it worked perfectly... :confused:

[saaya]

you should throw in some tp or kitchen paper to soak up the condensed humidity :)

with a couple of layers more armaflex tape nothing like this is needed with dry ice ...

[s7e9h3n]

Ummm........static bags are made to repel static from something which is inside the bag. Therefore, anything which is placed on top of the outside of the bag........... ;)

[Evil_Spork]

ooo good idea!

thats similar to th guys who put a towel under the gpu with phase change on it incase it drips :)

[eshbach]

bad news, motherboards might be ok. got a new DFI and still no boot...

dead san diegos + 1.

[JDizzle]

no, all of our runs were done like that. try different bios.

I've tried 3 different bios and prime failes after 2 hours at 2.34GHZ. When I was using the original bios I couldn't even get this thing to boot at 240FSB.

I'm sorry to hear that man...Hope you have more luck with the next one.

Weird...So you had it just sitting on the box w/o the bag and then you could post? Maybe I'll try that. Don't I need the bag though so nothing will short out?

Read what I said above. You're just as likely to short something out when you place your mobo on top of the outside surface of an anti-static bag. It's the inside of an anti-static bag which is protected from static.

[JDizzle]

Alrite, I'll try to change a few things up and see if I get anymore of an overclock.
