David's Learning and Rambling Thread

[keny]

Where are you getting it from? We get it in from BOC, if I remember rightly, and the in-house price is £4/scoop or £16/bag. If I could steal you half a bag one Friday I would, but I don't think I could sneak it off-site.

I don't know when I'll go cold again - today was ideal: dry ice left over this week, the boss down in England for the weekend, no-one in the lab. today. I don't know that I'll get the same 'perfect storm' for a while again yet ...

Ideally I'd love to have an SSD set up with three O/Ss all tweaked for the appropriate tests but it'll have to wait until this summer when I can afford it.

Got the quote from here but it does seem pricey

I had a look on the web a while ago.

There's this place, which annoyingly doesn't specify weight:
http://www.chillistick.co.uk/dry-ice-products/dry-ice-packs-c-318_297.html

This place says £35/10 kg:

BOC have a depot near Glasgow:
http://www.boconline.co.uk/products/products_by_type/dry_ice_solid_co2.asp

This place does 10 kg for £35 or 23 kg for £50:
http://www.dioxice.com/home/16-mm-pellets-supplied-in-insulated-boxes.html

There's this place in Aberdeen:
http://www.highlandice.co.uk/product_range/dry_ice.htm

There's this place as well, but I don't know prices/delivery arrangements:
http://ice-cooling.co.uk/


EDIT: If I had such a thing as a free weekend I'd be really tempted to offer to split a 23 kg bag with you and bring my rig down! Unfortunately I've got 4 weeks to finish this damn thesis and I'm already mourning my lost Saturday morning

I would be willing to split a 23kg bag,and transporting it to glasgow would not be a problem as i drive a refrigerated artic @-27c up to glasgow every night

Also you may have saved me a quid or two with those links £35 plus vat, thats about £42 ish delivered for 10kg

 

[David]

A couple of those are incl. VAT I'm sure ...

I'll see how this thesis goes - there may need to be a weekend of beer and dry ice at some point this summer if you're up for it ...

Always up for a session of benching

 

[David]

Got the 531 to 4.4 GHz, but it's only just stable. Hoping I can run the benchmarks at >= 4.2 GHz because then I can keep the RAM at ~1100 MHz or higher and hopefully kick some arse in the wprime1024m and superpi32m tests...

 

[Woomack]

I was able to push most my P4 / 775 to ~4.4-4.5GHz but wprime and ucbench not much higher than 4.2GHz. About -30*C idle at 1.65-1.68V that was max in bios ... almost killed P5K WS so I didn't try any vmods especially that board wasn't mine.

Just got a email back of this place.

hi Mark,

Thank you for your email.

Yes £35.00 is for the 10 Kgs of dry ice - The total cost including delivery, polystyrene carton and 10 Kilos of dry ice would be £60.00 + Vat.

Please let me know if you require any other information.

holy moly....

 

[Woomack]

about the same price here ... LN2 is cheaper but you need dewar and at least in my country some contacts as noone will sell you LN2 in retail ... thats why I got SS, nothing special but at least I can use it everytime I want without spending ~£50 / weekend

 

[David]

MUST ... NOT... SPEND ... MONEY

How much did your SS cost you, if you don't mind me asking? Where did you get it from?

 

[Woomack]

looks like this ( well now there is some dust here and there ), I really needed something " small " as I have it in my quite small room ... friend sent me info from one polish forum that someone is selling it for ~£200 with shipping ... I was thinking like 10 minutes .
Should make -55*C idle but I haven't seen lower than ~-52*C. Good enough for most gear, maybe not as good as LN2 but with my budget its perfect for daily benching.

 

[David]

Oooh ... £200 is less than 2.5x the cost of an H100 ... I might need to look into a SS once I start my job

 

[David]

PS: E1200 appears to have an FSB wall around ~475 MHz. Trying to see if I can beat my frequency score so far but not having much luck :-\

Going for the silly volts option isn't working.

 

[Woomack]

It's hard to find good SS in this price. Most cost about £350+. I got info that 1st owner bought it for ~£650 , 2 years ago+.

About E1200 ... I had similar wall for E1600 and if I'm right most of these cpus have max fsb somewhere near 500MHz.

 

[David]

The 915 hits 4 GHz on stock voltages! I like these sorts of chips . I doubt I'll get close to Woomack's 5.2 GHz, but I'll get as high as I can and fill in the couple of tests we don't have scores for.

EDIT: It's making me work for 4.2 GHz, however

 

[David]

Got 4.66 GHz, which was getting hard to keep stable enough to boot. Going to try and get the longer benches done at 4.66 GHz before shooting for max valid. 1.5 V, and the thing is getting warm ...

 

[David]

One of my sodding threads keeps dying in wPrime ... at 1.56 V and going to hit the oh-so-familiar heat issues soon ...



EDIT: and there we are ... no 4.6 GHz wPrime-ness for David

Extra Edit: Did snag a 4.8 GHz valid though http://valid.canardpc.com/show_oc.php?id=2285641

 

[David]

I'm within THREE MPT of gaining some points back for the P-D 925 ucbench, but I just can't get there

Cheers Bobnova also sent me a PM with some advice.

A bit of tweaking and playing has upped what I get out of UCBench by ~10% after some playing. I've got the 820 back in now, and taking my time to properly play around with it. I've already got a score that'll see me move up one place. Aiming for at least one more
