ICE ICE baby :) (low temperature topic)

Re: ICE ICE baby (low temperature topic)

The purpose is to OC a DUAL CPU system

Even a dual athlon xp board would be faster. They make dual opteron boards too and dual pentiums.

Re: ICE ICE baby (low temperature topic)

Yes, definitely it would be, and even will ...but I want some serious brand mobo, not just like tyan and supermicro, which I have, but no OCing ...And doing this isn't about havin superior performance, it's just about comparison: how it is not necessary to buy new hardware at all time, even this dinosaur can perform well in certain games, such as BF2, Serious SAM 2, Flatout 2, Rainbow Six: Las vegas 2 and many more...

Re: ICE ICE baby (low temperature topic)

I guess I'm gonna stick with the 173,5MHz FSB/DIMM and leave it just like that - it is reasonable, because it usually is true that an aggressive timing setup is more than squeezing some extra raw power. At 175,5 , the machine can withstand only medium settings, which is not a good offer at all, but more importantly it runs! So the clocking achievement is finally reached, now just tu tweak out some stuff and leave it, no more torture for this board.

In the end I cannot know for sure if it is the caps that cannot fulfill my desire to be stable at the most extreme clock settings, so I'm gonna take one of my VP6s and give 'em some rubycon MBZ lytic caps all over the VRM and Vcore output, to see how it performs...then will try some polys, but I have no idea which I should use - this problem is to be solved by you guys, since you got more experience. Any thoughts?

Re: ICE ICE baby (low temperature topic)

One simple, and easy "OC Helper" I have found is a 80mm-90mm hole saw. Put an extra fan on the side of your case, and help blow nice cool outside air into and ontop of the motherboard. I do this a lot with mobo's that come with good sized heatsinks on the NB, but no fan. Fan grills are easy to get, and you can make it look pro. Just always check the angle of air flow on a fan (without ducting, the fans don't blow straight down, they blow at an outward angle), and place it accordingly.

Re: ICE ICE baby (low temperature topic)

Nope, 175,5 is proven unstable, stress test for 30 min passed, but immediate run of BF2 made it freeze, again repeated - same thing. So now, i'm testing 174,5MHz at most aggressive timing, this time it runs, I play the game, but when exiting the game, it freezes. OK, so what's causing this - I blame the RAM, coz making an ECC SDR module to run over 40MHz off their spec is quite an impudence. But maybe its the caps that cannost withstand the pressure bestowed upon them, so my last resort of all this effort is to recap it either with some polys or my Rubycons MBZ...both will be tested, but no idea when, will post.

Re: ICE ICE baby (low temperature topic)

But I loveeee to have MCZ series due to their lower ESR...

Re: ICE ICE baby (low temperature topic)

too much heat and too much cold for the the computer is bad.

Where are you getting at? the BCS (Balcony Cooling Systems) setup is over, now I use the Cooler Master's HAF 932, see for yourself:

Re: ICE ICE baby (low temperature topic)

Seems the board/CPU are not fond of high voltage settings at higher frequencies - the computer runs stable at 173,5MHz at 1.85v, but not at 2.05v...same counts for 174,6MHz, which can stand only 1.90v...very interesting...Still performing some test, then the final test will be the 24h Prime95 - when all my grand tweakings are done.

Re: ICE ICE baby (low temperature topic)

The case is worth more than the CPUs/Mobo.

Re: ICE ICE baby (low temperature topic)

Everybody says that when they see it - got used to hear this already. Iwill MPX2, as mentioned, is going to be placed in my second one .

But don't worry, I do have contemporary desires, such as this, and exactly in the same case:



I just love big things

Re: ICE ICE baby (low temperature topic)

So option 174,6MHz is out, 173 remains still good, will update.

Re: ICE ICE baby (low temperature topic)

Gotta quote myself: I really don't know this time what it could be: It's like settings above 173,5MHz are stable (I get into the OS, can do whatever) till the moment I run the BF2 and play it for about 10-15 min, sometimes even 30min. The thing is it won't freeze (like when using the original chipset heatsink), but eleganlty jumps to the OS' desktop...then again, I can go all the way again, and again, smooth desktop fall ...never reboots, never freezes...so what is it? It definitely is not a cooling issue using that case, I tested all possible heat emitters by my fingertips (MOSFETs on the mobo have tall heatsinks, also the two near the AGP slot & the VGA's regulators are breezed quite well, just warm), each temperature readings are within nominal specs (CPU 35 max, VGA 50 max - counting in celsius). The VGA's clocked up high though, need to put it back to be sure...but do you folks have any other ideas?

Re: ICE ICE baby (low temperature topic)

let prime95 run in torture mode for a while (hours)

if it stops bc. of wrong results, the CPUs are calculating wrong (they're waay past the rating already), maybe causing those BF2 crashes

[Shodan486]

Re: ICE ICE baby (low temperature topic)

yup, I agree...but i still suspect the caps - they've really been put through some stress under my command, probably can't catch the breath like before. Will have one recapped and have the same HW setup and we'll see. Still any more ideas are welcome...

[Shodan486]

Re: ICE ICE baby (low temperature topic)

in our local shop...but I saw it on ebay too. It's HAF 932, look it up on Cooler Master webpage, great photos, amazing cooling performance...

[Shodan486]

Re: ICE ICE baby (low temperature topic)

Ending my OC challenge with this board, now the results:

At FSB 173MHz (everest reports 173,5MHz)
DIMMs at 173 (+everest reading), timings @ 2-2-2-5 CL2

Vcore - 1.85v
VCC3.3 - 3.5v (right now testing 3.4v, minor glitches, but OK)

I guess the Sanyos are quite stressed, the only thing I need to do at last is to recap one of the others I have with the rubys Ultra Low ESR and try something more (and maybe less voltage too)...

So this is my stable setup, reached those 1300MHz !!!! Yeah, that was my primary goal . ROCK SOLID (let's see for how long )

Re: ICE ICE baby (low temperature topic)

Seems to me they should be able to come up with a well cooled case that doesn't become butt ugly in the process.

[Shodan486]

Re: ICE ICE baby (low temperature topic)

I have swapped the 7600GS for the 7950GT I ordered on ebay...It looks nice, even the perfrormance has increased - LightsMark 2008 jumped from 40.1FPS to 56.9FPS...BF2 runs smoother, will test more...Rite now I'm just adjusting the lowest voltage possible for it... will update in an hour or two.

Re: ICE ICE baby (low temperature topic)

Heh, atleast your dual CPU setup is faster than a dual core Atom.

Re: ICE ICE baby (low temperature topic)

I love dual P3s. Last pentium/intel desktop I owned
I only had a cheap VIA chipset gigabyte board and it died. It's a shame, because I had spire whisperrock HSFs on it and it looked pretty good, tried to GIS them, but all reviews and pics I could find were just the plain wire grille, can't find a pic of the the domed cutout grille mine had.

Now I have a hex core 1090T though
